Search results: a life in food

I am increasingly concerned about the proliferation of research studies sponsored and funded by food, beverage, or supplement companies with a vested interested in the outcome.  These almost invariably come to conclusions in favor of the sponsor’s food product.

You must understand that I am not searching for sponsored studies in any systematic way.  They just appear in the tables of contents of journals I typically read and are easily identified by their titles.

My plan is to post a list of sponsored research studies every time I accumulate 5 examples.  My first post in this series appeared March 16.

Recent examples

1.  Purified palmitoleic acid for the reduction of high-sensitivity C-reactive protein and serum lipids: A double-blinded, randomized, placebo controlled study, by Adam M. Bernstein, MD, ScD, Michael F. Roizen, MD, Luis Martinez, MD, MPH.  Journal of Clinical Lipidology 2014;8:612–617.

• Conclusion: Purified palmitoleic acid may be useful in the treatment of hypertriglyceridemia with the beneficial added effects of decreasing LDL and hs-CRP and raising HDL.
• Sponsor: Tersus Pharmaceuticals (maker of Provinal palmitoleic acid).  Dr. Roizen is chair of the Scientific Advisory Board of Tersus Pharmaceuticals and chair of the Cleveland Clinic Wellness Institute.

2.  Whey Protein Supplementation Preserves Postprandial Myofibrillar Protein Synthesis during Short-Term Energy Restriction in Overweight and Obese Adults, by Amy J Hector, George R Marcotte, Tyler A Churchward-Venne, Caoileann H Murphy, Leigh Breen,Mark von Allmen, Steven K Baker, and Stuart M Phillips.  J Nutrition 2015;145:246–52.

• Conclusion: We conclude that whey protein supplementation attenuated the decline in postprandial rates of MPS [Myofibrillar Protein Synthesis] after weight loss, which may be of importance in the preservation of lean mass during longer-term weight loss interventions.
• Sponsor: The Dairy Research Institute through the Whey Protein Research Consortium.

3.  Natural cocoa consumption: Potential to reduce atherogenic factors? By Brian K. McFarlin, Adam S. Venable, Andrea L. Henning, Eric A. Prado, Jill N. Best Sampson, Jakob L. Vingren, David W. Hill.  J Nutritional Biochemistry 2015: in press.

• Conclusion: Collectively, these findings indicate that acute natural cocoa consumption was associated with decreased obesity-related disease risk.
• Sponsor: The Hershey Company

4.  The effect of a high-egg diet on cardiovascular risk factors in people with type 2 diabetes: the Diabetes and Egg (DIABEGG) study—a 3-mo randomized controlled trial, by Nicholas R Fuller, Ian D Caterson, Amanda Sainsbury, Gareth Denyer, Mackenzie Fong, James Gerofi, Katherine Baqleh, Kathryn H Williams, Namson S Lau, and Tania P Markovic.  Am J Clin Nutr 2015; 101:705-713.

• Conclusion: High egg consumption did not have an adverse effect on the lipid profile of people with T2D [type 2 diabetes] in the context of increased MUFA [monounsaturated fatty acid] and PUFA [polyunsaturated fatty acid] consumption. This study suggests that a high-egg diet can be included safely as part of the dietary management of T2D, and it may provide greater satiety.
• Sponsor: Australian Egg Corporation

5.  Dietary Flaxseed Independently Lowers Circulating Cholesterol and Lowers It beyond the Effects of Cholesterol-Lowering Medications Alone in Patients with Peripheral Artery Disease.  Andrea L Edel, Delfin Rodriguez-Leyva, Thane G Maddaford, Stephanie PB Caligiuri, J Alejandro Austria, Wendy Weighell, Randolph Guzman, Michel Aliani, and Grant N Pierce.  J. Nutr. 2015; 145:749-757.

• Conclusion: Milled flaxseed lowers total and LDL cholesterol in patients with PAD [peripheral artery disease] and has additional LDL-cholesterol–lowering capabilities when used in conjunction with CLMs [cholesterol-lowering medications].
• Sponsor: Flax2015, the Canola Council of Canada, and others.

The Wall Street Journal, hoping to generate some controversy, got me involved in a point/counterpoint about the Paleo Diet: “Is a Paleo diet healthy?”

It can be, but this is a point/counterpoint.  Hence, I took the position “NO: You Lose Too Much Pleasure for Dubious Benefits.”  

Here’s what I said:

Nutritionist that I am, the first questions I have about any diet are: What is it? Is the rationale behind it logical? And does it promote health?

A paleo diet is based on the premise that our genes govern what’s best for us to eat. We evolved to eat whatever could be hunted or gathered. This makes it OK to eat leaves, shoots, roots, seeds, eggs, animals, birds and fish, but not OK to eat grains, legumes, dairy or processed foods.

Why do paleo proponents think the ills of modern society stem from a mismatch between our genetics and today’s typical diets? The cave men, some argue, didn’t suffer from diseases such as obesity, heart disease and diabetes.

The problem with that theory is that we really don’t know what our Paleolithic ancestors ate. As I often argue, determining what people eat is the single most intellectually challenging question in nutrition science. It is extraordinarily difficult to get an accurate idea of what people ate yesterday, let alone 10,000 to a million or more years ago.

In reality, scientists are nowhere near being able to match genes to specific kinds of diets. The reason cave men didn’t have chronic diseases like diabetes is more likely because they didn’t live long enough and lacked antibiotics, rather than because they didn’t eat carbohydrates.

Variety is key

What we know for sure is that the fundamental tenets of nutrition are variety, balance and moderation. The fewer kinds of foods consumed, the greater the chance of nutrient deficiencies. So while it is certainly possible to eat healthfully on a paleo diet, restricting whole groups of relatively unprocessed foods can make this more challenging. It also can take some of the joy out of eating by forcing people to give up foods that they love or that are part of their cultural heritage.

While there is no doubt that highly processed “junk” foods are unhealthy and should be kept to a minimum, grains and legumes are hardly the enemy. Diets that vary enormously—from the traditional high carbohydrate, rice-based cuisines of Asia to those of the Mediterranean rich in grains and olive oil—have been shown to promote health and longevity.

Yes, grains contain glutens, and bread and pasta are caloric, but such foods are also delicious and part of traditional diets in nearly every culture. Yes, legumes contain unpleasant phytochemicals, but these are mostly destroyed by cooking, and beans and peas are excellent sources of vegetable protein. If you eat foods from animal sources, why restrict dairy? Cheese and yogurt are lovely foods, and I, for one, cannot imagine life without an occasional serving of ice cream.

Eating less works

Any restrictive diet helps to reduce calorie intake, so it isn’t surprising that there are studies linking paleo to weight loss, lower blood sugar and a reduced risk of cancers for which obesity is a risk factor. Eating less works every time.

So does eating a largely plant-based diet. Research suggests that we can reduce risks for today’s diseases of affluence by eating more foods from plant sources and balancing calorie intake with expenditure. To the extent the paleo diet achieves these goals, it is a reasonable choice.

But food is so much more than bundles of nutrients. What we eat also nourishes us psychologically and culturally. So while a paleo diet isn’t necessarily bad, why bother? I’d be sad to miss all those delicious forbidden foods.

My e-mail inbox is filled with items about the Academy of Nutrition and Dietetics (AND, formerly the American Dietetic Association).  Its “seal of approval” on Kraft cheese singles (as discussed in an earlier post) was embarrassing—so embarrassing that it was discussed by Jon Stewart: “The Academy is an Academy in the same way this [Kraft Singles] is cheese” (the clip starts at 4:37).

The Onion also had some fun with this.

But now there is even more about how food companies buy the opinions of dietitians.

Candice Choi writes about how Coca-Cola pays dietitians to promote its drinks as healthy snacks (for an example of one of the paid posts, click here).  She explains that the dietitians

wrote online posts for American Heart Month, with each including a mini-can of Coke or soda as a snack idea. The pieces — which appeared on nutrition blogs and other sites including those of major newspapers — offer a window into the many ways food companies work behind the scenes to cast their products in a positive light, often with the help of third parties who are seen as trusted authorities.

Ms. Choi quotes a Coca-Cola spokesman:

“We have a network of dietitians we work with,” said Sheidler, who declined to say how much the company pays experts. “Every big brand works with bloggers or has paid talent.”

Other companies including Kellogg and General Mills have used strategies like providing continuing education classes for dietitians, funding studies that burnish the nutritional images of their products and offering newsletters for health experts. PepsiCo Inc. has also worked with dietitians who suggest its Frito-Lay and Tostito chips in local TV segments on healthy eating.

These are individual actions.  But at last the dietetic membership is objecting to the Academy’s partnership with Kraft.

1. They have started a Change.org petition to #RepealTheSeal.
2. The President of the New York State AND chapter (NYSAND), Molly Morgan, sent out a note in support of the petition.

Thank you to the many of you that have expressed your concern and disappointment about the Academy of Nutrition and Dietetics partnership with Kraft. This issue has been reviewed carefully by the NYSAND Board of Directors and the entire board is in support of actively taking steps to share our members concerns. Below are the action steps that NYSAND is taking:

–       Last week (March 11, 2015) the NYSAND Sponsorship Task Force recommendations were received and yesterday (March 16, 2015) at the March NYSAND Board of Directors meeting the Sponsorship Task Force recommendations were reviewed. Please stay tuned for more updates and note that a motion will be forth coming this week for the board to take the next step in addressing sponsorship for NYSAND.

–       Today (March 17, 2015) a letter was sent to the Academy president and emailed to several Academy leaders expressing the views that our members have shared and that as an Affiliate we are not comfortable responding with the talking points provided by the Academy on this issue.

–       Dietitians have started a petition, “Repeal the Seal”; NYSAND will be sharing this on our Affiliate Facebook and Twitter pages and encourages all members who share the concern to sign the petition as well. CLICK HERE to sign the petition.

3.  The AND national CEO, Patricia M. Babjak, sent out this letter to members, also on March 17:

Let me begin by apologizing for the concerns caused by the education initiative with Kraft. The Academy and the Foundation are listening. As a member-driven organization, the Academy’s staff and leadership hear your concerns and welcome your input.

Unfortunately, recent news articles misstated a collaboration as a Kids Eat Right “endorsement” of Kraft Singles, and that it represents a “seal of approval” from Kids Eat Right, the Foundation, or the Academy. It is not an endorsement. It is not a seal of approval. We understand this distinction is of little consequence to many Academy members who are concerned with the perception. We are working on a solution.

In addition, we are working to establish a joint, member-driven Member Advisory Panel. This Panel will work closely with both Boards to:

• Establish dialogue with members
• Gather input and give feedback on member issues
• Make specific recommendations

Recognizing sponsorship as a significant issue of concern among members, the House of Delegates leadership team, who also serve on the Board of Directors, scheduled a dialogue on sponsorship for the upcoming virtual House of Delegates meeting, May 3. We encourage all members to reach out to your delegates and share your thoughts on the benefits of, concerns about and suggestions for the sponsorship program. The Academy and Foundation Boards are looking forward to your input.

Applause to members who are speaking out.

As I said in an interview with TakePart:

The food companies have learned from tobacco and drugs and other industries like that how to play this game…Let’s confuse the science, let’s cast doubt on the science, let’s shoot the messenger, let’s sow confusion.

But since everyone has to eat, the food industry has been given a pass on its pay-to-play practices….

The capital N news…is that dietitians are fighting back at last.

I hope they join Dietitians for Professional Integrity and insist that the leadership respond to their concerns.

Addition: A dietitian sends this communication from the Executive Board of the California Dietetic Association to members about the Kraft situation:

We would like to direct your attention to what the California Dietetic Association (CDA) has done to address our own issues surrounding sponsorship. We heard your concerns regarding CDA Annual Conference sponsorship and we have listened. We voted and McDonalds was not invited as a sponsor in 2015. This decision has impacted our finances; however, we believe it was important to respond to our member feedback. In addition, an ad hoc committee approved by the CDA executive board, reevaluated the sponsorship guidelines. The new sponsorship policy will be posted soon on www.dietitian.org.

As reported in today’s New York Times, the Academy of Nutrition and Dietetics (AND, formerly the American Dietetic Association) has licensed its Kids Eat Right seal to—get this— Kraft Singles.

But no, AND says, this is not an endorsement.  Kraft is merely a “proud supporter of” AND’s Kids Eat Right program.

As the Times understates the matter,

Over the last few years, the academy been criticized from some of its members and health advocates over what they contend are its overly cozy ties to industry.

Kraft is well known as a sponsor of AND.  Such seals are usually money-raising gimmicks.

I’m wondering if “proud supporter of” means that Kraft pays AND for use of this seal. If so, I’d like to know what the seal costs.

AND members: do any of you know?

Recall the debacle over the Smart Choices logo some years ago.

The press had a field day with the Smart Choices logo on Froot Loops.  As Rebecca Ruiz at Forbes puts it, “the uproar over the program has conveyed a definitive message to industry: Don’t try to disguise a nutritional sin with a stamp of approval.”

Somehow, Kraft and AND seem to have missed this lesson.

Additions: Andy Bellatti sends these links to a statement from Sonja Connor, AND’s president and the website describing the program.

Thanks to Yoni Freedhoff for sending this explanation:

And this enlightening note from ABC News:

The academy…said the appearance of the logo on the processed cheese product is not an endorsement or seal of approval. It’s more like an ad for Kids Eat Right, according to the academy, though, in a reversal of how most ads work, Kraft paid the advertiser — the academy — an undisclosed amount to place the logo.

The New England Journal of Medicine has a new study that suggests the need to rethink whether to feed peanuts to babies.

As the Wall Street Journal explains, peanut allergies can be life-threatening and they are increasing among the population.

Dr. Gideon Lack and his colleagues randomly assigned infants to be fed peanuts (really, peanut butter) until they were five years old.  The children fed peanuts had far fewer peanut allergies than those who were not exposed to peanuts.

Of the more than 500 infants who showed no signs of peanut allergies at the start of the trial, the prevalence of peanut allergies at age 5 was 13.7% in the avoidance group and only 1.9% in the consumption group (see the journal’s video for an easy explanation).

A result like this is extremely unlikely to have occurred by chance.

Dr. Lack got the idea for the study when he noticed that peanut allergies were rare in Israel.  Israeli infants are routinely offered foods made with peanuts, whereas British and American parents have been told not to feed peanuts to young children.

The authors conclude:

Our findings showed that early, sustained consumption of peanut products was associated with a substantial and significant decrease in the development of peanut allergy in high-risk infants. Conversely, peanut avoidance was associated with a greater frequency of clinical peanut allergy than was peanut consumption, which raises questions about the usefulness of deliberate avoidance of peanuts as a strategy to prevent allergy.

The implications are clear: expose young children to peanut butter (the accompanying editorial explains how to do this safely).  And to prevent choking, don’t give them peanuts until they can chew.

Other newspaper articles on this topic:

• USA Today
• Washington Post
• New York Times

The 2015 Dietary Guidelines Advisory Committee (DGAC) issued its more than 500-page report yesterday.

Before I say anything about it, please note that this report informs, but does not constitute, the Dietary Guidelines. The agencies—USDA and HHS—write the actual Guidelines and are not expected to do so until the end of this year.

Here are what I see as the highlights (these are direct quotes)

• A healthy dietary pattern is higher in vegetables, fruits, whole grains, low- or non-fat dairy, seafood, legumes, and nuts; moderate in alcohol (among adults); lower in red and processed meat; and low in sugar-sweetened foods and drinks and refined grains.
• A diet higher in plant-based foods…and lower in calories and animal-based foods is more health promoting and is associated with less environmental impact than is the current U.S. diet.
• It will take concerted, bold actions…to achieve and maintain the healthy diet patterns, and the levels of physical activity needed to promote the health of the U.S. population. These actions will require a paradigm shift to an environment in which population health is a national priority and where individuals and organizations, private business, and communities work together to achieve a population-wide “culture of health” in which healthy lifestyle choices are easy, accessible, affordable, and normative.

Some facts and statements from the report (not direct quotes).

• Half the energy intake in U.S. diets comes from a combination of burgers and sandwiches (~14%), desserts and sweet snacks (8.5%), sugary beverages (6.5%), mixed dished made with rice, pasta, and other grains (5.5%, savory snacks (~5%), pizza (4.3%), and meat, poultry and seafood mixed dishes (~4%).
• Nearly half of total sugar intake comes from beverages other than milk and 100% fruit juice

The report comments on issues under current debate.

• Saturated fat: “replacing SFA with unsaturated fats…significantly reduces total and LDL cholesterol…Strong and consistent evidence…shows that replacing SFA [saturated fatty acids] with PUFA [polyunsaturated fatty acids] reduces the risk of CVD [cardiovascular] events and coronary mortality…For every 1 percent of energy intake from SFA replaced with PUFA, incidence of CHD [coronary heart disease] is reduced by 2 to 3 percent. However, reducing total fat (replacing total fat with overall carbohydrates) does not lower CVD risk.”
• Sugars: “Strong and consistent evidence shows that intake of added sugars from food and/or sugar sweetened beverages are associated with excess body weight in children and adults…Strong evidence shows that higher consumption of added sugars, especially sugar-sweetened beverages, increases the risk of type 2 diabetes among adults and this relationship is not fully explained by body weight.[Theae findings are] compatible with a recommendation to keep added sugars intake below 10 percent of total energy intake.”
• Food labels: “Consumers would benefit from a standardized, easily understood front-of-package (FOP) label on all food and beverage products to give clear guidance about a food’s healthfulness.” [This refers to the recommendations of the Institute of Medicine that I’ve written about previously; they disappeared without a trace.]
• Soda taxes: “Economic and pricing approaches, using incentives and disincentives should be explored to promote the purchase of healthier foods and beverages. For example, higher sugar-sweetened beverage taxes may encourage consumers to reduce sugar-sweetened beverage consumption.”
• SNAP: “Policy changes within the federal Supplemental Nutrition Assistance Program (SNAP), similar to policies in place for the WIC program, should be considered to encourage purchase of healthier options, including foods and beverages low in added sugars. Pilot studies using incentives and restrictions should be tested and evaluated.”

The DGAC recommends (these are direct quotes but not necessarily complete):

• Establish local, state, and Federal policies to make healthy foods accessible and affordable and to limit access to high-calorie, nutrient-poor foods and sugar-sweetened beverages in public buildings and facilities.
• Set nutrition standards for foods and beverages offered in public places.
• Improve retail food environments and make healthy foods accessible and affordable in underserved neighborhoods and communities.
• Implement the comprehensive school meal guidelines (National School Lunch Program) from the USDA that increase intakes of vegetables (without added salt), fruits (without added sugars), and whole grains.
• Limit marketing unhealthy foods to children.
• Make drinking water freely available to students throughout the day.
• Ensure competitive foods meet the national nutrition standards (e.g., Dietary Guidelines for Americans).
• Eliminate sugar-sweetened beverages [from schools].
• Nutrition Facts label should include added sugars (in grams and teaspoons).

And for all federal nutrition programs, the DGAC recommends:

• Align program standards with the Dietary Guidelines for Americans so as to achieve the 2015 DGAC recommendations and promote a “culture of health.”

Congratulations to this committee for its courageous recommendations.

Why courageous?  See my previous comments on the objections to such advice.

The next step: public comment:

The public is encouraged to view the independent advisory group’s report and provide written comments at www.DietaryGuidelines.gov for a period of 45 days after publication in the Federal Register. The public will also have an opportunity to offer oral comments at a public meeting in Bethesda, Maryland, on March 24, 2015. Those interested in providing oral comments at the March 24, 2015, public meeting can register at www.DietaryGuidelines.gov. Capacity is limited, so participants will be accepted on a first-come, first-served basis.

Here’s your chance to support this committee’s excellent ideas and demonstrate public approval for diets that promote the health of people and the planet.

Note: the reactions to the report are pouring in and I will deal with them next week.  Enjoy the weekend!

The World Health Organization (WHO) released two reports within the last week aimed at preventing noncommunicable diseases.  Although the second is all about reducing sugar intake, the first report is about everything but.

1.  The Global Status Report on Noncommunicable Diseases, 2014.* 

The WHO press release points out that the report calls for:

more action to be taken to curb the epidemic, particularly in low- and middle-income countries, where deaths due to NCDs are overtaking those from infectious diseases. Almost three quarters of all NCD deaths (28 million), and 82% of the 16 million premature deaths, occur in low- and middle-income countries.

How?  By working to achieve 9 targets:

• Target 1: A 25% relative reduction in risk of premature mortality from CVDs, cancer, diabetes, chronic respiratory diseases.
• Target 2: At least 10% relative reduction in the harmful use of alcohol, as appropriate, within the national context.
• Target 3: A 10% relative reduction in prevalence of insufficient physical activity.
• Target 4: A 30% relative reduction in mean population intake of salt/sodium.
• Target 5: A 30% relative reduction in prevalence of current tobacco use in persons aged 15+ years.
• Target 6: A 25% relative reduction in the prevalence of raised blood pressure or contain the prevalence of raised blood pressure, according to national circumstances.
• Target 7: Halt the rise in diabetes and obesity.
• Target 8: At least 50% of eligible people receive drug therapy and counselling (including glycaemic control) to prevent heart attacks and strokes.
• Target 9: An 80% availability of the affordable basic technologies and essential medicines, including generics, required to treat major NCDs in both public and private facilities.

Don’t dietary sugars have something to do with diabetes and obesity?  How come no specific target?  This is especially odd in light of the second report.

2. Guideline: Sugars Intake for Adults and Children [see updated, revised publication released March 2015]

The WHO makes three recommendations about intake of added (“free”) sugars:

• A reduced intake of free sugars throughout the lifecourse (strong recommendation).
• Reducing the intake of free sugars to less than 10% of total energy intake (strong recommendation).
• A further reduction of the intake of free sugars to below 5% of total energy intake (conditional recommendation)

Why no target for sugar reduction to 10% of energy  in the first report?

The omission is glaring.  Could politics be involved?  It’s hard to think of any other explanation.

WHO needs to speak with one voice on NCD targets, guidelines, and recommendations.

* Along with the NCD target report, WHO also released:

• Noncommunicable diseases country profiles 2014
• Fact sheet on noncommunicable diseases
• More on noncommunicable diseases

**Thanks to Dr. Karen Sokal-Gutierrez for alerting me to the lack of a sugar target.
