Are Plant-Based “Milks” The Margarine of the 21st Century?

Full fat dairy doesn’t make you fat or give you heart disease. But nutritional guidelines still continue to recommend the substitution of non-fat or low-fat dairy for full fat, something that flies in the face of an overall movement to consume less processed foods.

The rise of plant-based milks resembles in many ways the rise of margarine as a substitute for butter. In both cases, industry and misguided scientists collaborated to produce an industrial product to substitute for a natural food, based on an unproven projection of health benefits. Subsequent studies have shown that this was an unmitigated health disaster, as the trans fats created in the production of margarine substantially increase the risk of heart disease.

Anti-Dairy Propaganda

Vegan/vegetarian sources of nutritional information like one green planet make unsubstantiated claims about the benefits of plant-based milks and the dangers of traditional milk:

the consumption of dairy products has been linked to everything from increased risk of ovarian and prostate cancers to ear infections and diabetes. Fortunately, plant-based milks provide a convenient and healthful alternative to cow’s milk. And if you are currently making the transition to a dairy-free diet, you will find that going dairy-free has never been easier. Soy, almond, hemp, coconut, and rice milks, among others, are taking over the dairy case—and claiming supermarket aisles all their own.

Growth of Plant-Based “Milks”

In response to consumers desire for healthier alternatives to dairy, non-dairy liquid milk-like substitutes  have been thriving. Almond milk, the current darling of plant-based milks (PMB) , sales have grown 250% in the last 5 years during which time,  the total milk market has shrunk by more  than $1 billion.

In western Europe, sales of almond, coconut, rice and oat milks doubled in the five years to 2014; in Australia they rose threefold, and in North America sales shot up ninefold, according to Euromonitor.

Big global beverage food and drinks companies have been entering the PBM market recognizing that American consumers have become aware of the unhealthiness of sugar-sweetened beverages.

Coca-Cola, for example, recently purchased Unilever’s AdeS soya brand. and believes that PBM consumption will grow faster than any other segment of the beverage industry over the next 5 to 10 years. Coca-Cola also recently purchased the China Green brand of plant-based protein drinks.

What’s in Soy Milk and Why It’s Not Real Food

The plant-based milks are a mixed bag of highly processed liquids. Let’s look at soy milk which has been widely promoted as a healthy substitute for dairy. Empowered Sustenance points out that there is reason to be concerned about all the added ingredients found in Silk, a popular soy milk.

Soymilk (Filtered Water, Whole Soybeans), Cane Sugar, Sea Salt, Carrageenan, Natural Flavor, Calcium Carbonate, Vitamin A Palmitate, Vitamin D2, Riboflavin (B2), Vitamin B12.

The long list of ingredients give you an idea of how much processing is needed to approximate the nutritional components of real dairy. Whether adding back synthetic Vitamin D2, synthetic Vitamin A and calcium carbonate simulates the nutritional benefits of the naturally occurring vitamins in a naturally fatty milieu, is anyone’s guess.

Variable Nutritional  Content of Plant-Based “Milks”

Bestfoodfacts.org asked 3 academic nutritional PhD’s how they would advise consumers on substituting nondairy “milk:”

Dr. Macrina: Plant-based milks are quite variable in what they contain while cow’s milk is pretty standard. We know where cow’s milk comes from. Plant-based milks are manufactured and can have a variety of additives. I urge consumers to read the label to determine what’s best for them.

Dr. Savaiano: Yes, consumers should read the label very carefully. Plant-based drinks certainly can be a healthy choice depending on how they’re formulated.

Dr. Weaver: The plant-based beverages all cost a good deal more than cow’s milk. So, one needs to determine how much they want to pay for the nutrients and determine which nutrients you need to get from other foods. A main nutrient expected from milk is calcium. Only soy milk has been tested for calcium bioavailability (by my lab) which was determined to be as good as from cow’s milk. But none of the other plant beverages have been tested and they should be.

Is There Scientific Evidence To Support Replacing Milk and Dairy Products with Plant-based Drinks?

A recent review paper from Danish researchers attempted to answer the question:

Milk and dairy products: good or bad for human health? An assessment of the totality of scientific evidence. 

They concluded:

The most recent evidence suggested that intake of milk and dairy products was associated with reduced risk of childhood obesity. In adults, intake of dairy products was shown to improve body composition and facilitate weight loss during energy restriction. In addition, intake of milk and dairy products was associated with a neutral or reduced risk of type 2 diabetes and a reduced risk of cardiovascular disease, particularly stroke. Furthermore, the evidence suggested a beneficial effect of milk and dairy intake on bone mineral density but no association with risk of bone fracture. Among cancers, milk and dairy intake was inversely associated with colorectal cancer, bladder cancer, gastric cancer, and breast cancer, and not associated with risk of pancreatic cancer, ovarian cancer, or lung cancer, while the evidence for prostate cancer risk was inconsistent. Finally, consumption of milk and dairy products was not associated with all-cause mortality.

They went on to examine the question: Is there scientific evidence to substantiate that replacing milk and dairy products with plant-based drinks will improve health?

They noted the marked variation in nutritional content of the plant-based milks:

the nutrient density of plant-based milk substitutes varies considerably between and within types, and their nutritional properties depend on the raw material used, the processing, the fortification with vitamins and minerals, and the addition of other ingredients such as sugar and oil. Soy drink is the only plant-based milk substitute that approximates the protein content of cow’s milk, whereas the protein contents of the drinks based on oat, rice, and almonds are extremely low,

and their similarity to sugar-sweetened beverages:

Despite the fact that most of the plant-based drinks are low in saturated fat and cholesterol, some of these products have higher energy contents than whole milk due to a high content of oil and added sugar.

Some plant-based drinks have a sugar content equal to that of sugar-sweetened beverages, which have been linked to obesity, reduced insulin sensitivity , increased liver, muscle, and visceral fat content as well as increased blood pressure, and increased concentrations of triglyceride and cholesterol in the blood

PBM and real milk also differ with respect to important electrolytes and elements:

Analyses of several commercially available plant-based drinks carried out at the Technical University of Denmark showed a generally higher energy content and lower contents of iodine, potassium, phosphorus, and selenium in the plant-based drinks compared to semi-skimmed milk

and some PBM contain potentially dangerous components:

Also, rice drinks are known to have a high content of inorganic arsenic, and soy drinks are known to contain isoflavones with oestrogen-like effects. Consequently, The Danish Veterinary and Food Administration concluded that the plant-based drinks cannot be recommended as full worthy alternatives to cow’s milk which is consistent with the conclusions drawn by the Swedish National Food Agency

Finally, the authors emphasize the importance of the health effects of whole foods rather than individual nutrients. Plant-based milks are not whole or real foods:

The importance of studying whole foods instead of single nutrients is becoming clear as potential nutrient–nutrient interactions may affect the metabolic response to the whole food compared to its isolated nutrients. As the plant-based drinks have undergone processing and fortification, any health effects of natural soy, rice, oats, and almonds cannot be directly transferred to the drinks, but need to be studied directly.

The Skeptical Cardiologist Recommendation

Consumers should be very cautious in their consumption of plant-based milks. Eerily reminiscent of the push to switch from butter to margarine in the past, these drinks cannot be considered as healthier than dairy products.

They are creations of industry, promoted and produced by large companies like Coca-Cola and Unilever, whose goal is profit, not consumer’s health.

The PBMs are not true whole or real foods and their nutritional content varies wildly. Some resemble sugar-sweetened beverages like Coca-Cola.

If one of the synthetic ingredients added to these beverages turns out to have the markedly negative health effect that trans fats had, the analogy to margarine will be complete.

My  Eternal Fiancee’ has true lactose intolerance and has baristas substitute almond or soy milk when ordering a latte’.  I understand that but I’ve been trying to convince her (with increasing success lately!)  to drink my Chemex pour-over coffee and adulterate it with nothing, butter, cream or coconut oil.

Skeptically Yours,

Beware Of More Misinformation From The American Heart Association On Coconut Oil and Saturated Fats

In a “presidential advisory” to the American Heart Association (AHA)  a panel of experts last week  strongly endorsed the heart healthy benefits of replacing any and all saturated fats in our diet with vegetable oils (like corn , soy, and canola oil) which contain predominantly poly  or mono unsaturated fats.

Examining the metrics of this article it appears that the vast majority of news media reporting on it have lead with a headline that reads:

  Coconut oil isn’t actually good for you, the American Heart Association says     

Given this brazen attempt by the AHA to smear coconut oil’s reputation I felt compelled to revisit my analysis of coconut oil from a year ago. I’ve included new discussion on a key paper referenced by the AHA advisory and some words of wisdom from Gary Taubes.

Coconut Oil: Poster Child for Dietary Fat Confusion

Coconut oil (CO) is a microcosm of the dietary confusion present in the U.S. On one hand a CO Google search yields a plethora of glowing testimonials to diverse benefits: Wellness Mama lists “101 Uses for Coconut Oil,” Authority Nutrition lists “10 Proven Health Benefits.”

On the other hand, the  American Heart Association (AHA) and the USDA’s Dietary Guidelines For Americans warn us to avoid consuming coconut oil  because it contains about 90% saturated fat (SFA) which is a higher percentage than butter (about 64% saturated fat), beef fat (40%), or even lard (also 40%)

In many respects, the vilification of coconut oil by federal dietary guidelines and the AHA resembles the inappropriate attack on dairy fat and is emblematic of the whole misguided war on dietary fat. In fact, the new AHA advisory  after singling out coconut oil goes on to cherry-pick the data on dairy fat and cardiovascular disease in order to  support their faulty recommendations for choosing low or nonfat dairy..

The AHAs simple message to replace all saturated fats in your diet with poly unsaturated fats (PUFAs) or monounsaturated fats (MUFAs) is flawed because:

  1. All saturated fats are not created equal :the kinds of saturated fats in coconut oil differs markedly from both dairy SFAs and beef SFAs . Some  SFAs may have beneficial effects on blood lipids, weight, and cardiovascular health.

  2. The types of nonSFAs in vegetable oils differ markedly and may have differential effects on cardiovascular health.

All Saturated Fats Are Not Created Equal!

Saturated fats are divided into various types based on the number of carbon atoms in the molecule. Depending on length, they differ markedly in their metabolism, absorption and effects on lipid profiles.

The major SFA in coconut oil, lauric acid, has a 12 carbon chain and is thus considered a medium chain fatty acid (MCFA).

The AHA advisory makes a cursory attempt to address the huge hole in their logic primarily relying on a meta-regression analysis published in 2003 by Mensink, et al., and concludes:

The Mensink meta-regression analysis determined the effects on blood lipids of replacing carbohydrates with the individual saturated fatty acids that are in common foods, including lauric, myristic, palmitic, and stearic ac- ids. Lauric, myristic, and palmitic acids all had similar effects in increasing LDL cholesterol and HDL cholesterol and decreasing triglycerides when replacing carbohydrates

In summary, the common individual saturated fats raise LDL cholesterol. Their replacement with monounsaturated or polyunsaturated fats lowers LDL cholesterol. Differences in the effects of the individual fatty acids are small and should not affect dietary recommendations to lower saturated fat intake.

But if we examine what the actual paper by Mensink et al (available in full here) we find their conclusions are the exact opposite of the AHA:

Lauric acid greatly increased total cholesterol, but much of its effect was on HDL cholesterol. Consequently, oils rich in lauric acid decreased the ratio of total to HDL cholesterol. Myristic and palmitic acids had little effect on the ratio, and stearic acid reduced the ratio slightly.

The differences in the effects of the individual fatty acids are not small they are quite significant if we look at the totality of the effects on lipids relevant to cardiovascular disease. In their discussion, Mensink, et al go on to say:

Our results emphasize the risk of relying on cholesterol alone as a marker of CAD risk. Replacement of carbohydrates with tropical oils markedly raises total cholesterol, which is unfavorable, but the picture changes if effects on HDL and apo B are taken into account.

What’s more :

The picture may change again once we know how to interpret the effects of diet on postprandial lipemia, thrombogenic factors, and other, newer markers. However, as long as information directly linking the consumption of certain fats and oils with CAD is lacking, we can never be sure what such fats and oils do to CAD risk.

This graph from Mensink, et al. shows what would happen to the total/HDL cholesterol ratio if we substituted various foods in place of 10% mixed fat. Theoretically a lower ratio is more heart healthy. Look at the drastic differences between palm oil, coconut oil and butter, all of which are condemned by the AHA

 

Misguided Dietary Fat Recommendations

The  AHA experts have doubled down on their recommendation to use cooking oils that have less saturated fat such as canola and corn oil. They advise, in general, to “choose oils with less than 4 grams of saturated fat per tablespoon.”

Screen Shot 2016-05-07 at 12.28.40 PMCanola and corn oil, the products of extensive factory processing techniques, contain mostly mono or polyunsaturated fats which have been deemed “heart-healthy” on the flimsiest of evidence.

The most recent data we have on replacing saturated fat in the diet with polyunsaturated fat comes from the Minnesota Coronary Experiment performed from 1968 to 1973, but published in 2016 in the BMJ.

Data from this study, which substituted liquid corn oil in place of the usual hospital cooking fats, and corn oil margarine in place of butter and added corn oil to numerous food items, showed no overall benefit in reducing mortality. In fact, individuals over age 65 were more likely to die from cardiovascular disease if they got the corn oil diet.

Cherry-Picking Data

The new AHA presidential advisory doesn’t include this study or  data from the Sydney Heart Study, another study with negative results for substituting PUFAs for SFAs.

As Gary Taubes pointed out in a post for Larry Husten’s cardiobrief.org blog, the AHA experts cherry-picked four “core trials” that  agreed with their hypothesis and excluded the ones that don’t agree:

They do this for every trial but the four, including among the rejections the largest trials ever done: the Minnesota Coronary Survey, the Sydney Heart Study, and, most notably, the Women’s Health Initiative, which was the single largest and most expensive clinical trial ever done. All of these resulted in evidence that refuted the hypothesis. All are rejected from the analysis. And the AHA experts have good reasons for all of these decisions, but when other organizations – most notably the Cochrane Collaboration – did this exercise correctly, deciding on a strict methodology in advance that would determine which studies to use and which not, without knowing the results, these trials were typically included.

Coconut Oil: The Bottom Line

After all is said and done, it would appear that coconut oil, despite coming from a vegetable, resembles dairy fat in many ways.

It is more likely than not that coconut oil, like dairy fat, reduces your chances of obesity and heart disease, especially when compared to the typical American diet of highly processed and high carbohydrate foods.

Although containing lots of saturated fat, the SFAs in coconut oil are drastically different from other dietary sources of SFA.  The medium chain fatty acids like lauric acid which make up the coconut are absorbed and metabolized differently from long chain fatty acids found in animal fat.

The only explanation for dietary guidelines advising against coconut oil and dairy fat is the need to stay “on message” and simplify food choices for consumers, thus continuing the vilification of all saturated fats.

Substituting corn oil (or other vegetable oils with lots of linoleic acid) for foods containing saturated fats does not lower risk of heart disease and may promote atherosclerotic outcomes like heart attack and stroke.

Finally, I agree with Taubes that we deserve good scientific studies proving without a doubt that these drastic changes in diet are truly helping:

“telling people to eat something new to the environment — an unnatural factor, à la virtually any vegetable oil (other than olive oil if your ancestor happen to come from the Mediterranean or mid-East), …..is an entirely different proposition. Now you’re assuming that this unnatural factor is protective, just like we assume a drug can be protective say by lowering our blood pressure or cholesterol. And so the situation is little different than it would be if these AHA authorities were concluding that we should all take statins prophylactically or beta blockers. The point is that no one would ever accept such a proposal for a drug without large-scale clinical trials demonstrating that the benefits far outweigh the risks. So even if the AHA hypothesis is as reasonable and compelling as the AHA authors clearly believe it is, it has to be tested. They are literally saying (not figuratively, literally) that vegetable oils — soy, canola, etc — are as beneficial as statins and so we should all consume them. Maybe so, but before we do (or at least before I do), they have a moral and ethical obligation to rigorously test that hypothesis, just as they would if they were advising us all to take a drug.”

Cocovorically Yours,

-ACP

For those seeking more information.

This graph is from the BMJ paper which also included a meta-analysis of all randomized studies substituting linoleic acid for saturated fat.  The data do not favor substituting corn oil for saturated fat

Unsure About Taking A Statin For High Cholesterol? Consider A Compromise Approach

In an earlier post the skeptical cardiologist introduced Geo, a 61 year old male with no risk factors for heart attack or stroke other than a high cholesterol. His total cholesterol was 249, LDL (bad) 154, HDL (good) 72 and triglycerides 116.

His doctor had recommended that he take a statin drug but Geo balked at taking one due to concerns about side effects and requested my input. My first steps were to gather more information.

-I calculated his 10 year risk of stroke or heart attack at 8.4% (treatment with statin typically felt to benefit individuals with 10 year risk >7.5%) and as I have previously noted, this is not unusual for a man over age 60.

-I assessed him for any hidden  or subclinical atherosclerosis and found

The vascular ultrasound showed below normal carotid thickness and no plaque and his coronary calcium score was 18,  putting him at the 63rd  percentile. This is slightly higher than average white men his age.

So Geo definitely has atherosclerotic plaque in his coronary arteries. This puts him at risk for heart attack and stroke but not a lot higher risk than most men his age.

Strictly speaking, since he hasn’t already had a heart attack or stroke, treating him with a statin is a form of primary prevention. However, we know that atherosclerotic plaque has already developed in his arteries and at some point, perhaps years from now it will have consequences.

What is the best approach to reduce Geo’s risk?

It’s essential  to look closely at lifestyle changes in everyone to reduce cardiac risk.

The lifestyle components that influence risk are

  1. Cigarette Smoking (by far the strongest)
  2. Diet
  3. Exercise
  4. Obesity (Obviously related to #1 and #2)
  5. Stress
  6. Sleep

Patients who try to change to what they perceive as a heart healthy diet by switching to non-fat dairy and eliminating all red meat will not substantially lower risk (see here.) Even if you are possess the rock-hard discipline to stay on a radically low fat diet like the Esselstyn diet or the Pritikin diet there are no good data supporting their  efficacy in preventing cardiac disease.

Geo was not far from theMediterranean diet I recommend but would probably benefit from increased veggie and nut consumption. He was not overweight and he doesn’t smoke. I encouraged him to engage in 150 minutes of moderate exercise weekly.

Low Dose, Intermittent Rosuvastatin

I engaged in shared decision-making with Geo.  Informing him, as best I could, of the potential side effects and benefits of statin therapy.

After a long discussion we decided to try a compromise between no therapy and the guideline recommended moderate intensive dose statin therapy.

This approach utilizes a low dose of rosuvastatin taken intermittently with the goal of minimizing any statin side effect but obtaining some of the benefits of statin drugs on  cardiovascular risk reduction.

I have many patients who have been unable to tolerate other statin drugs in any dosage due to statin related muscle aches but who tolerate this particular  treatment and I  see substantial reductions in the LDL (bad) cholesterol with this approach.

Studies have shown that rosuvastatin 5–10 mg or atorvastatin 10–20 mg given every other day produce LDL-C reduction of 20–40 %

Studies have also shown that In patients with previous statin intolerance, rosuvastatin administered once or twice weekly (at a mean dose of 10 mg per week) achieved an LDL-C reduction of 23–29% and was well tolerated by 74–80 % of patients.

In a recent report from a specialized lipid clinic, 90 % of patients referred for intolerance to multiple statins were actually able to tolerate statin therapy, although the majority was at a reduced dose and less-than-daily dosing.

Results in Geo

After several months of taking 5 mg rosuvastatin twice weekly Geo felt fine with no discernible side effects. He obtained repeat cholesterol  levels:

His LDL had dropped 52% from 140 to 92.

Hopefully, this LDL reduction plus the non-cholesterol lowering beneficial properties of statins (see here) will substantially lower Geo’s risk of heart attack and stroke.

We need randomized studies testing long-term outcomes using this approach to make it evidence-based. But in medicine we frequently don’t have studies that apply to  specific patient situations. In these cases shared decision-making in order to find solutions that fit the individual patient’s concerns and experience becomes paramount.

Faithfully Yours,

Dear Kaldi’s, Please Stop Serving Candied Bacon: It Is A Health And Gastronomic Abomination

The skeptical cardiologist enjoys bacon (in moderation), often with quiche, despite the fact that The Who (World Health Organization, not the band that John Entwhistle played for) classifies it as a carcinogen.

Enjoying bacon has become more difficult these days due to the development of a most disturbing fad: the adulteration of bacon  with sugar in some way, shape, or form.

The Eternal Fiancee’ recently ordered a bacon, egg and cheddar on croissant sandwich at my favorite St. Louis coffee spot, Kaldi’s when to our horror, candied bacon was served.

An inquiry at the serving counter  revealed that Kaldi’s only serves candied bacon; you can’t get any that hasn’t been turned into a monstrosity!

I find candied bacon to be an abomination.  All I can taste is sugar and any subtleties of the bacon or its preparation are eclipsed by the saccharine bulk of the sugar.

If this graphic (from my fitness pal.org) is to be believed, the three slices in her sandwich added 40 grams of sugar. This is the equivalent of 10 teaspoons of sugar and the amount of sugar in a bottle of Coke.

 

 

 

 

Readers of this blog know that I consider sugar, not fat, as the major toxin in our diet, contributing to obesity, diabetes and ultimately heart attack and stroke. I’ve also pointed out that huge amounts of added sugar are hidden in smoothiescoffee drinks, and non fat yogurt.

The massive amount of sugar in this candied bacon is not exactly stealth: you can tell it from the first bite. However, there is nothing in the description of the croissant sandwich that alerts you to the fact that your bacon will be transmogrified into candy.

Serving only candied bacon in my opinion is the equivalent of only serving coffee that has had sugar added to it and Kaldi’s should know better.

Kaldi’s is proud of their community commitment which includes support for the Juvenile Diabetes Research Foundation. What about supporting healthier food choices (with no added sugar)  for kids so they are less likely to get diabetes and if they have diabetes will be  less likely to be poorly controlled?

I implore Kaldi’s to stop this madness.

Antisucroporcinely Yours,

-ACP

N.B. The Eternal Fiancee’ just tried to order a smoothie at the Clayton Kaldi’s and discovered to her horror that their peanut butter contains hydrogenated oils and added sugar. Yikes!

More Incredibly Bad Science From Dr. Esselstyn’s Plant-Based (Vegan) Diet Study

A while back the skeptical cardiologist exposed “The incredibly bad science behind Dr. Esselstyn’s plant-based diet.

The diet has the catchy slogan “eat nothing with a face or a mother” and Esselstyn was featured in the vegan propaganda film “Forks Over Knives.”

After detailing the lack of science I concluded:

Any patients who were not intensely motivated to radically change their diet would have avoided this crazy "study" like the plague.

This "study" is merely a collection of 18 anecdotes, none of which would be worthy of publication in any current legitimate medical journal.

Three of the 18 patients have died, one from pulmonary fibrosis, one presumably from a GI bleed, and one from depression. Could these deaths be related to the diet in some way? We can't know because there is no comparison group.

The post garned little attention initially but in the last few months several hundred visitors per day apparently read it and Essesltyn followers have started leaving me testimonials to the diet along with nasty comments.

Here’s are some typical ones (with my comments in red)

“If your (sic) not backed by some meat industry or cardiac bypass group I would be much surprised.”

I am completely free of bias. Nobody is paying me anything to do the research and writing I do. My only purpose is to find the truth about diet in order to educate my patients properly. I have  saved many more patients from bypass surgery than I have referred for the procedure.

“it is so arrogant to think the only science could come from clinical studies which may be funded by an interested party.”

Doctors like randomized (and preferably blinded) clinical studies because they minimize the bias introduced by interested parties like patients and zealous investigators (like Dr. E)  motivated to see positive outcomes. Small, non-randomized studies can only generate ideas and hypotheses which larger, randomized studies can prove with a greater degree of certainty.

“the entire nentire western medical system is skewed due to the big pharma influence…unfortunately western medicine believes the only science is the pen and the scalpel..whereas …history is the best teacher of all…”

By pen I assume you mean medications. If we examine history as  you suggest we see that life expectancy was 50 years in 1945  but today in developed countries it is around 80 years. This advance corresponds to (among other things) advances in vaccines, antibiotics, anti-cancer drugs, cardiac and blood pressure medications and surgery: the pen and the scalpel. It does not correspond to following a vegan diet.

“Your foolishness is the embarrassment.”

Thank you for this insightful comment! I’m considering it as my epitaph.

One man felt that changing to the Esselstyn diet dramatically improved his cardiac situation and commented:

“Nothing like bashing something that works just because you want to eat meat. .”

I do enjoy meat in moderation but I also really enjoy vegetables, nuts, fish, legumes, olive oil and avocados. I looked into Esselstyn’s diet in detail because it stands out as particularly misguided in banning nuts, avocados, fish and olive oil to heart patients.

..”.So sicking (sic) to see people talk trash about something that works so well… It saved my life…”

I’m happy you are doing well with your cardiac condition but it is impossible to know what would have happened to you on a more reasonable diet such as the Mediterranean diet (which actually has legitimate scientific studies supporting it). And again criticizing Esselstyn’s ideas and “study” can hardly be considered trash talk.

“I personally have followed dr. esselstyn’s program for what will be 5 years in 11/17 and have made tremendous gains in my cardio pulmonary function….my cardiologist looks at me in wonder…why are you here? and often says , if everyone did what you have…Id be out of business…so…isnt that telling and sad?”

I’m glad you’re doing well with the program, most patients can’t follow this kind of diet for more than a few months.  But perhaps we shouldn’t judge its effectiveness until  we make sure you don’t suffer a heart attack next week. Your cardiologist is wrong: see what I wrote about “dealing with the cardiovascular cards you’ve been dealt.” Some individuals inherit genes that guarantee progressive and accelerated atherosclerosis that will kill them at an early age despite the best lifestyle.

“…the phrase “follow the money” comes to mind…and since theres no big money to be made….science will attempt to dispell the results and thousands of years of history that proves this dietary system works…”

Using a scientific approach to analyze Esselstyn’s diet (which tries to claim a scientific basis) seemed appropriate to me but I wasn’t motivated by money. I’m looking for what is best for my patients, pure and simple.

The Plural of Anecdote Is Not Data

One man wrote:

“But since this is only anecdotal evidence – it must be junk science…”

Esseslstyn devotees like to post what their personal experience is with the diet but as skeptical medicine has pointed out “the plural of anecdote is not data.” 

One woman described in detail a good response her husband had after starting the diet following a heart attack:

I’m concerned about the skeptical cardiologist going after the person of dr. Esselstyn versus the science, such as quoting how you States dr. Esselstyn came up with the diet. So there may be a personal bias there. I’m sure there are more people out there on the esselstyn diet that are not noted in the study years ago. I hope there is another book coming out

I’ve reviewed in detail my comments about how Esselstyn came up with the diet but I am at a loss to find any ad hominem attack.

This woman went on to say

We will keep you posted, as my husband is willing to get another cardiac Cath and 12 months to visually see the difference after the diet.

I have to point out that if his cardiologist performs a cardiac cath (which carries risks of stroke, heart attack and death) for the sole purpose of checking the effect of the diet he is engaging in unethical medical behavior and likely insurance fraud. By the way, I hope that your husband is on a statin like most of Dr. Esselstyn’s are!:)

and a man wrote

Calling Essylstein ilk shows a little too much biased hatred on your part

Please note the definition of ilk “a type of people or things similar to those already referred to.” No pejorative there. And no ad hominem attack.  I wrote:

 It is possible that the type of vegan/ultra-low fat diets espoused by Esselstyn and his ilk have some beneficial effects on preventing CAD, but there is nothing in the scientific literature which proves it.

I should be able to criticize the methods and ideas of Dr. E without it being considered an attack on his person

Completely wrong. Esselstyn has saved my life. His book explains it all, how the endothelium cells get ruined, inflammation … heart attack proof (his words). One does not continue as head of the Cleveland Wellness Center if one is a quack.

Words are easy to come by on the interweb but Dr. E’s are not supported by science and as for the “Cleveland Wellness Center” it is probably not wise to get me started. Dr. E ‘s program is listed as being part of the Cleveland Clinic Wellness Center which is an attempt to capitalize on the market for pseudoscientific enterprises. He is not the director. The director recently came under intense criticism for promoting anti vaccine quackery. (See here).

The Wellness Center promotes so-called functional, integrative, complementary and alternative approaches. (Functional medicine is fake medicine!) These are approaches that have not been proven to work and could arguably be called quackery. (Let me be clear, however, I am not calling Dr. Esselstyn a quack but the fact that he is part of the Wellness Center does not add any scientific validity to his work.)

“I’m sure there are more people out there on the esselstyn diet that are not noted in the study years ago. I hope there is another book coming out”

Fake News, Fake Science

As a matter of fact, Dr. E has been hard at work over the last 30 years and has added a grand total of 176 patients who are considered “adherent” to the diet: about 6 per year. The “original research” was published in The Journal of Family Practice in 2014. Unfortunately the bad science present in the original publication has only been amplified.

In addition to any randomization or suitable control group for comparison, the data collection techniques are unacceptable:

“In 2011 and 2012 we contacted all participants by telephone to gather data. If a participant had died, we obtained follow-up medical and dietary information from the spouse, sibling, off-spring or responsible representative.”

In other words, there was no actual systematic review of medical records, autopsies or death certificates, just word of mouth from whomever answered the phone.

“Patients who avoided all meat, fish, dairy, and knowingly, any added oils throughout the program were considered adherent.”

Imagine, if you will, that your husband died 10 years ago and you received a call from Dr. E’s office or perhaps Dr. E himself and he asks you if your husband “avoided all meat, fish, dairy and added oils.”  For one thing, it would be very difficult for you to answer that question with any degree of accuracy: was your husband cheating on Dr. E’s diet when you weren’t looking, do you remember his entire diet from 10 years ago?

For another thing, you know that the caller has an agenda. If your husband died of a heart problem the caller is not going to be happy until he/she gets you to admit that your husband had some guacamole on Cinco de Mayo in 2002. If he’s alive and doing well, the caller is likely to be satisfied with a simple answer that , yes, he’s following the diet.

Yes, we have more data from Dr. E but it turns out to be even more incredibly bad than the first lot.

Let the anecdotes and ad hominem attacks begin!

Dr. P’s Heart Nuts: Preventing Death In Multiple Ways

The skeptical cardiologist has finally prepared Dr. P’s Heart Nuts for distribution. IMG_8339The major stumbling block in preparing them was finding almonds which were raw (see here), but not gassed with proplyene oxide (see here), and which did not contain potentially toxic levels of cyanide (see here).

During this search I learned a lot about almonds and cyanide toxicity, and ended up using raw organic almonds from nuts.com, which come from Spain.

I’ll be giving out these packets (containing 15 grams of almonds, 15 grams of hazelnuts and 30 grams of walnuts) to my patients because there is really good scientific evidence that consuming 1/2 packet of these per day will reduce their risk of dying from heart attacks, strokes, and cancer.

IMG_7965The exact components are based on the landmark randomized trial of the Mediterranean diet, enhanced by either extra-virgin olive oil or nuts (PREDIMED, in which participants in the two Mediterranean-diet groups received either extra-virgin olive oil (approximately 1 liter per week) or 30g of mixed nuts per day (15g of walnuts, 7.5g of hazelnuts, and 7.5g of almonds) at no cost, and those in the control group received small nonfood gifts).

After 5 years, those on the Mediterranean diet had about a 30% lower rate of heart attack, stroke or cardiovascular death than the control group.

It’s fantastic to have a randomized trial (the strongest form of scientific evidence) supporting nuts, as it buttresses consistent (weaker, but easier to obtain), observational data.

Trademark

I applied for a trademark for my Heart Nuts, not because I plan to market them, but because I thought it would be interesting to possess a trademark of some kind.

The response from a lawyer at the federal trademark and patent office is hilariously full of mind-numbing and needlessly complicated legalese.

Heres one example:

"DISCLAIMER REQUIRED
Applicant must disclaim the wording “NUTS” because it merely describes an ingredient of applicant’s goods, and thus is an unregistrable component of the mark.  See 15 U.S.C. §§1052(e)(1), 1056(a); DuoProSS Meditech Corp. v. Inviro Med. Devices, Ltd., 695 F.3d 1247, 1251, 103 USPQ2d 1753, 1755 (Fed. Cir. 2012) (quoting In re Oppedahl & Larson LLP, 373 F.3d 1171, 1173, 71 USPQ2d 1370, 1371 (Fed. Cir. 2004)); TMEP §§1213, 1213.03(a).

The attached evidence from The American Heritage Dictionary of the English Language shows this wording means “[a]n indehiscent fruit having a single seed enclosed in a hard shell, such as an acorn or hazelnut”, or “[a]ny of various other usually edible seeds enclosed in a hard covering such as a seed coat or the stone of a drupe, as in a pine nut, peanut, almond, or walnut.”  Therefore, the wording merely describes applicant’s goods, in that they consist exclusively of nuts identified as hazelnuts, almonds, and walnuts.

An applicant may not claim exclusive rights to terms that others may need to use to describe their goods and/or services in the marketplace.  See Dena Corp. v. Belvedere Int’l, Inc., 950 F.2d 1555, 1560, 21 USPQ2d 1047, 1051 (Fed. Cir. 1991); In re Aug. Storck KG, 218 USPQ 823, 825 (TTAB 1983).  A disclaimer of unregistrable matter does not affect the appearance of the mark; that is, a disclaimer does not physically remove the disclaimed matter from the mark.  See Schwarzkopf v. John H. Breck, Inc., 340 F.2d 978, 978, 144 USPQ 433, 433 (C.C.P.A. 1965); TMEP §1213.

If applicant does not provide the required disclaimer, the USPTO may refuse to register the entire mark.  SeeIn re Stereotaxis Inc., 429 F.3d 1039, 1040-41, 77 USPQ2d 1087, 1088-89 (Fed. Cir. 2005); TMEP §1213.01(b).

Applicant should submit a disclaimer in the following standardized format:

No claim is made to the exclusive right to use “NUTS” apart from the mark as shown."

I’ve gotten dozens of emails from trademark attorneys offering to help me respond to the denial of my trademark request. Is this a conspiracy amongst lawyers to gin up business?

Nuts Reduce Mortality From Lots of Different Diseases

The most recent examination of observational data performed a meta-analysis of 20 prospective studies of nut consumption and risk of cardiovascular disease, total cancer, and all-cause and cause-specific mortality in adult populations published up to July 19, 2016.

It found that for every 28 grams/day increase in nut intake, risk was reduced by:

29% for coronary heart disease

7% for stroke (not significant)

21% for cardiovascular disease

15% for cancer

22% for all-cause mortality

Surprisingly, death from diseases, other than heart disease or cancer, were also significantly reduced:

52% for respiratory disease

35% for neurodenerative disease

75% for infectious disease

74% for kidney disease

The authors concluded:

If the associations are causal, an estimated 4.4 million premature deaths in the America, Europe, Southeast Asia, and Western Pacific would be attributable to a nut intake below 20 grams per day in 2013.

If everybody consumed Dr. P’s Heart Nuts, we could save 4.4 million lives!

Meditativeterraneanly Yours,

If you’re curious about why nuts are so healthy, check out this recent meta-analysis, a discussion of possible mechanisms of the health benefits of nuts complete with references:

Nuts are good sources of unsaturated fatty acids, protein, fiber, vitamin E, potassium, magnesium, and phytochemicals. Intervention studies have shown that nut consumption reduces total cholesterol, low-density lipoprotein cholesterol, and the ratio of low- to high-density lipoprotein cholesterol, and ratio of total to high-density lipoprotein cholesterol, apolipoprotein B, and triglyceride levels in a dose–response manner [4, 65]. In addition, studies have shown reduced endothelial dysfunction [8], lipid peroxidation [7], and insulin resistance [6, 66] with a higher intake of nuts. Oxidative damage and insulin resistance are important pathogenic drivers of cancer [67, 68] and a number of specific causes of death [69]. Nuts and seeds and particularly walnuts, pecans, and sunflower seeds have a high antioxidant content [70], and could prevent cancer by reducing oxidative DNA damage [9], cell proliferation [71, 72], inflammation [73, 74], and circulating insulin-like growth factor 1 concentrations [75] and by inducing apoptosis [71], suppressing angiogenesis [76], and altering the gut microbiota [77]. Although nuts are high in total fat, they have been associated with lower weight gain [78, 79, 80] and lower risk of overweight and obesity [79] in observational studies and some randomized controlled trials [80].

What Can We Learn About Heart-Healthy Lifestyle From The Tsimane People of the Amazon Rainforest ?

The skeptical cardiologist has been in Washington, DC attending the Scientific Sessions of the American College of Cardiology for the last three days in an attempt to upgrade his cardiology knowledge and obtain CMEs for all the various areas he needs CME (echo/nuclear/CT/vascular).

I’ve written some posts for SERMO, a physician social media site,  on interesting presentations from the meeting.

Here’s my take on one paper (published simultaneously in The Lancet) that is of general interest:

I’m a big advocate of coronary artery calcium (CAC) scans for helping make decisions on individual patients with intemediate risk for CAD. Several speakers at this year’s American College of Cardiology Meetings presented convincing data supporting this approach, providing more information to get patients off the fence about taking statins.

However, CAC apparently would be a useless test in the Tsimane (pronounced chee-MAH-nay) people according to a study presented at  the ACC meeting and published simultaneously in The Lancet.

Researchers performed CT scans on 700 of  these “forager-horticulturalist”  people, indigenous to the Bolivian Amazon Rainforest and found very little calcium suggesting that they have an amazingly low rate of atherosclerosis compared to we who have to live in the industrialized world.

Obviously CT scanners are not portable so the Tsimane traveled by river and jeep from the Amazon rainforest to Trinidad, a city in Bolivia and the nearest city with a CT scanner. It took tribe members one to two days to reach the nearest market town by river, and then another six hours driving to reach Trinidad.

85% of the Tsimane people studied had CAC scores of 0. In those over age 75 years, 65% had CAC scores of 0, and just four individuals in their 80s had moderately elevated CAC (> 100). The incidence of CAC > 100 in the entire Tsimane population was 3%, which is about one tenth the prevalence in a matched industrialized population. In addition, incidences of obesity, hypertension, high glucose concentrations, and cigarette smoking were rare overall.

The Tsimane live a subsistence lifestyle that includes hunting, gathering, fishing, and farming. They don’t eat at McDonalds and the men spend almost 7 hours pers day on physical labor. Their diet consists mostly of unprocessed fiber-rich carbohydrates with rice, plantain, manioc, corn, wild nuts, and fruit composing their staples. Fat consumption is 9% of calories versus 23% in the U.S.

Supporters of plant-based diets, of course, seized on these data to support the unsubstantiated claim that meat and dairy consumption is the main cause of atherosclerosis in western civilization.

Hillard Kaplan, one of the authors and a Professor of anthropology at the University of New Mexico said:

 “Their lifestyle suggests that a diet low in saturated fats and high in non-processed fibre-rich carbohydrates, along with wild game and fish, not smoking and being active throughout the day could help prevent hardening in the arteries of the heart. The loss of subsistence diets and lifestyles could be classed as a new risk factor for vascular aging and we believe that components of this way of life could benefit contemporary sedentary populations.”

However, the real cause of the low levels of coronary artery calcification in the Tsimane remains a mystery because this kind of observational study cannot establish causality. Perhaps it is the 17,000 steps a day that they walk  engaging in foraging and horticulturalism. Could it be due to the absence of processed food and added sugar? The Tsimane have high levels of parasitic infections: perhaps that is protecting them.

Of two things I am certain:

-The Tsimane don’t need statins.

-I prefer my lifestyle to munching on manioc and foraging all day.

Beware The Bitter Almond

As part of the Health Nuts Project, the skeptical cardiologist has been evaluating walnuts, hazelnuts and almonds which he plans to put in packets and distribute to patients and readers.

Previously, we discovered that most raw almonds from the US have been fumigated with a chemical called propylene oxide and that roasting almonds creates potentially carcinogenic chemicals.

Consequently, after considerable searching, I purchased raw organic almonds from a company called NutsinBulk. These turn out to be from Spain (where pasteurization of almonds is not required) and are quite tasty.

As I was munching on one of these almonds I suddenly noticed an incredibly bitter taste causing me to spit the chewed almond out. My first thought was that this almond had gone “bad” in some way. Perhaps a mold had crept into it. Looking at the pieces I had spit out, however, I could see no discoloration or other visible difference from the “normal” almonds.

Subsequent experimentation has revealed that about one in ten of these almonds is incredibly bitter and there is no way to predict this from  the external appearance of the almond.

The Source of Bitter Almonds

The sweet almond  that we are used to eating in the US is produced from one type of almond tree (Prunus amygdalus var. dulcis) and does not contain poisonous chemicals. However, the bitter almond that I encountered comes from a different type of almond tree (Prunus amygdalus var. amara).

Prunus amara trees were likely the original almond trees but over time the sweet almond trees have been selected for and now dominate. According to the LA Times and Paul Schrade, who provides bitter almonds to restaurants:

Until recent decades, most Mediterranean almond orchards were grown from seed, and the shuffling of genes resulted in a mix of bitter almond trees among the sweet. Growers liked to keep a few bitter trees around because they helped to pollinize the sweet varieties. The inclusion of bitter nuts gave snackers occasional unpleasant surprises, but they deepened the flavor of marzipan, almond milk and glazes for cakes. In Italy, bitter almond paste was traditionally used to make crisp amaretti cookies, and bitter almond extract flavored amaretto liqueur. In Greece, bitter almonds are used in soumada, a sweet syrup. (apparently cooking or adding alcohol eliminates the toxic cyanide)

There’s little large-scale cultivation of bitter almonds left in Spain and Italy, mostly just scattered trees remain, but it is still possible to buy raw bitter almonds at European specialty markets. Morocco and Iran now lead in commercial production of bitter almonds.

What Makes The Almonds Bitter: Amygdalin

The source of the bitterness is amygdalin:

A recessive gene causes bitter almond trees to produce in their shoots, leaves and kernels a toxic compound called amygdalin, which serves as a chemical defense against being eaten. When amygdalin is moistened, it splits into edible benzaldehyde, which provides an intense almond aroma and flavor, and deadly hydrocyanic acid, a fast-acting inhibitor of the respiratory system.

A variety of sources confirm that:

The lethal dose of raw bitter almonds depends on the size of the nuts, their concentration of amygdalin and the consumer’s sensitivity. But scientists estimate that a 150-pound adult might die from eating between 10 and 70 raw nuts, and a child from ingesting just a few.

YIKES!!!When I read this I was shocked. Could it be that consuming 10 of these raw  biter almonds would kill me.? How could I distribute these potentially lethal edibles to my patients?

Amygdalin (Laetrile) , Alternative Cancer Therapy and Quackery

In addition to bitter almonds, significant amounts of amygdalin are found in the stone fruit kernels of apricots, peaches and plums. A synthetic form of amygdalin called Laetrile achieved great notoriety in the 1980s as a cancer treatment. Although research had shown the chemical to be ineffective, it was embraced by “alternative” healers who claimed it was a “natural” cure for cancer which was being suppressed by a conspiracy between the US FDA, big pharma, and the the medical community.

Steve McQueen, suffering from pleural mesothelioma sought the care of a delisted American holistic orthodontist practicing in Mexico, William Kelley. The NY Times reported:

In July 1980, McQueen secretly traveled to Rosarita Beach, Mexico, to be treated by Mexican and American doctors using Dr. Kelley’s regimen. He received not only pancreatic enzymes but 50 daily vitamins and minerals, massages, prayer sessions, psychotherapy, coffee enemas and injections of a cell preparation made from sheep and cattle fetuses. McQueen was also given laetrile, a controversial alternative treatment made from apricot pits.

Although we hear little about Laetrile these days, like most snake oil it is still promoted by alternative medicine. For example, The notorious quack Dr. Mercola still promotes the idea that laetrile is a safe and effective treatment of cancer on his web site with a post that has been viewed over 700,000 times.

You Can Die From Eating Bitter Almonds

Certainly, there is considerable evidence that Laetrile can be toxic or lethal but bitter almonds can also cause lethal cyanide poisoning. A case report describes a woman with colon cancer who turned down potentially curative surgery/chemotherapy and turned to alternative treatments including Laetrile.  A helpful friend gave her a bag of bitter almonds for their “medicinal properties”, whereupon the woman consumed a slurry composed of 12 ground up almonds with water. Within 30 minutes she developed  severe cyanide poisoning with vomiting, abdominal pain, pulmonary edema, severe lactic acidosis and  loss of  consciousness.
Analysis of the bitter almonds showed they contained on average 6.2 mg of cyanide per almond. It is estimated that a lethal dosage of cyanide is 50 mg or 0.5 mg per kg body weight, thus the calculation that 10 almonds could kill someone weighing  60 kg or 132 pounds.
My  Search For Healthy Almonds Continues
The small amount of cyanide one gets from consuming a single bitter almond seems to have little effect. (Although the Mediterranean diet nutritionist Conner Middelman-Whitney , who spent time in Europe and encountered bitter almonds occasionally says that she does remember a weird, numb sensation in the mouth when they were consumed.)  It’s extremely unlikely that one of my patients would consume 10 of the bitter almonds (without reflexively spitting them out as I did) in a short period of time.
When I have consumed them I noticed no adverse effects but after such an encounter I stopped eating the almonds for the day.
However, I’m not interested in testing that theory. (Ability to taste amygdalin or smell cyanide varies between individuals, thus I can’t be certain that the bitter taste would serve as a reliable warning.)
Therefore,  I’ve concluded that I’m not going to distribute these potentially lethal almonds to my patients and will be removing them from the Dr. Pearson Health Nuts Packages.
My search for non-fumigated, non-cyanide-laced , non-carcinogenic almonds continues!
Cyanogenically Yours,

The Impact of Organic Foods On Human Health: European Perspective

The skeptical cardiologist obtains most of his groceries from Whole Foods, something the eternal fiancée insists on.  At least part of my preference is related to Whole Foods’ focus on organic produce and part to their focus on sustainable and healthier meat and fish.

A recent report from the European Parliament reviews the existing scientific evidence regarding the impact of organic food on human health. I think this document, (eu-organic-food) is a reasonable summary of the science in this area. The summary can be broken down into 4 key points:

  1. Very few studies have directly addressed the effect of organic food on human health. They indicate that organic food may reduce the risk of allergic disease and obesity, but this evidence is not conclusive. Consumers of organic food tend to have healthier dietary patterns overall. Animal experiments suggest that identically composed feed from organic or conventional production has different impacts on early development and physiology, but the significance of these findings for human health is unclear.

Meaning: We just don’t have good evidence to support routine use of organic foods.

2. In organic agriculture, the use of pesticides is restricted. Epidemiological studies point to the negative effects of certain insecticides on children’s cognitive development at current levels of exposure. Such risks can be minimised with organic food, especially during pregnancy and in infancy, and by introducing non-pesticidal plant protection in conventional agriculture. There are few known compositional differences between organic and conventional crops. Perhaps most importantly, there are indications that organic crops have a lower cadmium content than conventional crops due to differences in fertiliser usage and soil organic matter, an issue that is highly relevant to human health

My take. A 2014 review concluded that “the frequency of occurrence of pesticide residues was found to be four times higher in conventional crops, which also contained significantly higher concentrations of the toxic metal Cadmium

The review also concluded that ” the concentrations of a range of antioxidants such as polyphenolics were found to be substantially higher in organic crops/crop-based foods…… phenolic acids, flavanones, stilbenes, flavones, flavonols and anthocyanin.

3. Organic milk, and probably also meat, have a higher content of omega-3 fatty acids compared to conventional products, but this is not likely to be nutritionally significant in light of other dietary sources.

My take. I disagree. I wrote about why I only consume full-fat dairy products that are “organic” and come from grass-fed cows here. There are a lot of benefits, beyond increased omega-3 fatty acids, in consuming dairy that comes from cows that eat grass versus corn and are treated properly.

4. The prevalent use of antibiotics in conventional animal production is a key driver of antibiotic resistance. The prevention of animal disease and more restrictive use of antibiotics, as practiced in organic production, could minimise this risk, with potentially considerable benefits for public health.

My take. I agree. Cut out the antibiotics. Other countries seem to be able to do this.

I would also agree with the conclusion of  The Lancet’s editorial comment (Organic Food: Panacea for Health?)  on the EU paper:

Large, prospective, long-term studies are needed as well as deeper examination of agricultural policy and health. Much still rests on the provision of robust multidisciplinary research to guide future food choices for health.

Until we get such studies, I will be erring on the side of caution and consuming food with the least amount of pesticides, cadmium and antibiotics possible.

Nutella: Healthy and Natural Spread or Highly Processed, Slickly Marketed Junk Food?

It’s World Nutella day according to Ferrero, the Italian confectonery company and manufacturer of the globally beloved hazelnut-based spread.screen-shot-2017-02-05-at-6-28-42-am

“With Nutella we spread positive energy to families to bring more happiness to the world” we are informed. On this day, apparently, the world should be spreading Nutella on as many food products as possible, ramping up positive energy levels to unprecedented levels.

Here are some of the other products Ferrero sells:screen-shot-2017-02-05-at-9-08-21-am

Three of them are clearly recognized by consumers as candy.

Should Nutella be in the same category as tic-tacs?

 

 

Nutella Ingredients

Perhaps in anticipation of World Nutella Day, a graphic has been appearing on Twitter:

nutella-englisy

detailing the ingredients of Nutella. The English version of this was posted on Reddit on a subreddit that I can’t mention on my family-friendly blog. It is a translation of a graphic that was published in German originally.

screen-shot-2017-02-05-at-8-18-31-am
If you thought you were getting mostly hazelnuts under the lid as this Nutella website graphic implies, you will be disappointed.

I’m not sure where the original data for the graphic came from but it seems to be a reasonable illustration of how much of Nutella is made up of palm oil and sugar. A 2 tbsp serving of Nutella (37 grams) contains 12 grams of fat, 21 grams of sugar and 2 grams of protein. Only about 12% of Nutella comes from actual hazelnuts.

I don’t have any concerns from a cardiovascular risk standpoint with the fat content of either the palm oil or the hazelnuts in Nutella.

But the 5 teaspoons of sugar per serving screen-shot-2017-02-05-at-8-44-16-am

are just still another source of empty
sugar calories adding to the daily dietary glut of sugar consumers face when consuming highly processed foods.

Nutella definitely is a highly processed, highly sugared product that shouldn’t be a regular part of a healthy Mediterranean diet. Most of the ingredients have gone through  complex sourcing and factory processing although their marketing material strains to emphasize the freshness and naturalness of these ingredients.

screen-shot-2017-02-05-at-6-30-27-am

One ingredient not depicted on the now viral graphic of Nutella is vanillin. From Nutella’s ingredient graphic one might think the screen-shot-2017-02-05-at-6-34-38-amvanillin is being extracted from (per wikipedia)

“the seed pods of Vanilla planifolia, a vining orchid native to Mexico, but now grown in tropical areas around the globe.”

In reality, however, the Nutella people,  ” use synthetic vanillin, an aroma identical to the one naturally present in the vanilla pod.”

Is the Palm OIl In Nutella Carcinogenic?

Some question the healthiness of the palm oil in nutella, either due to its high saturated fat content or its carcinogenic potential. A european food safety authority paper in May, 2016 declared certain toxins found in palm oil in particular to be “genotoxic and carcinogenic”

EFSA assessed the risks for public health of the substances: glycidyl fatty acid esters (GE), 3-monochloropropanediol (3-MCPD), and 2-monochloropropanediol (2-MCPD) and their fatty acid esters. The substances form during food processing, in particular, when refining vegetable oils at high temperatures (approx. 200°C)

The highest levels of GE, as well as 3-MCPD and 2-MCPD (including esters) were found in palm oils and palm fats, followed by other oils and fats. For consumers aged three and above, margarines and ‘pastries and cakes’ were the main sources of exposure to all substances.

As a result, According to Reuters, In Italy, some products containing palm oil have been removed from grocer’s shelves and one pastry company has eliminated palm oil from it products, labeling them as “palm oil free.”

High temperatures are used to remove palm oil’s natural red color and neutralize its smell, but Ferrero says it uses an industrial process that combines a temperature of just below 200C and extremely low pressure to minimize contaminants.

Nutella has fought back, defending its use of palm oil, with television and print advertisements.

Healthier Alternatives To Nutella

Conner Middleman, nutritionist , cooking instructor and author of Zest For Life, has shared with me her recipe for Nutritella, a healthier version of Nutella you can make at home. She points out in her intro to the recipe:

Nutella was invented in the 1940s in the Piedmont region of northern Italy, where hazelnuts grow plentifully. Alas, modern, store-bought Nutella contains a mere 13% hazelnut and only a hint of cocoa; the rest is made up of sugar, palm oil and artificial vanilla flavoring. My home-made version of Nutella, on the other hand, contains very little sweetener (in the form of raw honey), 3 tablespoons of flavonoid-rich dark cocoa, and about 90% hazelnuts, which boast a particularly high concentration of antioxidants and healthy fats (mostly monounsaturated). This is not to say that you should eat this spread by the tablespoonful; its high fat content means it’s high in calories and it should be enjoyed in sensible amounts (1-2 tbsp/day). The good news is that a high-fat food such as this one keeps you sated for longer, and because it is made from whole, real foods, it’s not only rich in calories, but also in nutrients! 

Here’s the recipe:

1 cup/125g toasted hazelnuts (Trader Joe’s roasted Oregon hazelnuts work great here; alternatively buy plain, raw hazelnuts and roast them yourself as described below)

½ oz/2 tbsp/15g unsweetened cocoa

3 tbsp hazelnut oil (La Tourangelle is my favorite brand – available in the oils section of good supermarkets or online)

3 tbsp honey or maple syrup

2 tsp alcohol-free vanilla extract (e.g., Trader Joe’s)

6-8 tbsp milk/plant milk/water

If you are roasting the hazelnuts from scratch, preheat oven to 350F. Place nuts on a dry, clean baking sheet and roast for 8 minutes (set timer). Remove and tip hot nuts onto a clean kitchen towel (pictured here).

As they cool, the skins will loosen, crack and flake off. Gather up the towel by its corners and scoop together into a tight bundle. Hold the bundle with one hand and knead the nuts with the other through the cloth to rub the skins off them. Place bundle back on a flat surface and open; lift out the nuts and lightly shake off the skins. (Leave some skin on the nuts – it’s where most of the antioxidants reside.)

If using pre-roasted nuts, start here.

Place the hazelnuts in an electric blender with the cocoa, oil, honey/maple syrup and vanilla extract. Process on “high” for about 30-40 seconds until all the ingredients come together in a coarse paste.

With the motor running, add milk or water (whichever using), a tablespoon at a time, and keep processing until the mixture reaches the desired consistency.

Transfer to a clean glass jar and refrigerate. Keeps for at least 2 weeks.

You can check out Conner’s excellent website, Modern Mediterranean, replete with more recipes and information on the cancer-fighting benefits of the Mediterranean diet,  here. and her You-tube channel here.

Of course, the skeptical cardiologist Heart Nuts project advocates just eating  heartnutsunadulterated hazelnuts along with other healthy drupes, nuts and legumes for snacking and soon we will be distributing these to you using our trademark-pending walnut-auscultating squirrel, Sparky.
