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.

I was invited by CNN to comment on the announcement by Nestlé that it is removing artificial colors from its chocolates.

Here’s what I said:

(CNN) When food giant Nestle USA (to which I am, alas, not related) last month announced plans to remove all artificial flavors and colors from its chocolate candies, it understandably made headlines. According to the company, by the end of 2015, none of a group of 250 chocolate products including Butterfinger and Baby Ruth will contain artificial flavors or colors such as Red #40 or Yellow #5.

With the expectation that these chemicals will also disappear from the company’s other candies, it looks like the end of the use of artificial flavors and colors in anything but the cheapest food products. If that proves to be the case, it will be a welcome shift.

Nestle USA intends to advertise the reformulated products with a “No artificial flavors or colors” claim on package labels. If sales of the “no artificial” candies grow as expected, the company will surely extend the removal to all of its other colored and flavored food products. After all, Nestle’s international parent company — and the company’s competitors — will have to take notice and find ways to remove these chemicals from all their product lines.

Nestle USA has undeniable clout. It accounts for a quarter of the $100 billion in annual revenues of the more than century-old, privately held parent corporation, which itself is the largest food company in the world. This move surely will not only reverberate through the candy industry, but also affect every other major food company.

In substituting natural for artificial flavors and colors, Nestle USA is responding to what its customers are saying. The company’s own research indicates that Americans prefer their beloved candy brands to be free of artificial flavors and colors, while other surveys find majorities of respondents saying that artificial chemical additives negatively influence their buying decisions.

Nestle is also responding to decades of complaints from consumer advocates about the potential health risks of these chemicals, especially the dyes. Studies in experimental animals have linked high doses of food dyes to health problems, among them organ damage, cancer, birth defects, and allergic reactions. In humans, studies link food dyes to hyperactivity and other behavioral problems in young children.

The credibility of these studies and their implications for human health remain hotly debated. In the 1970s, for example, Ben Feingold, a physician in California, suggested that food additives caused children to become hyperactive. Much of the evidence for the “Feingold hypothesis” rested on anecdotal reports by parents, whereas double-blind, controlled clinical trials produced contradictory results.

On the basis of current evidence, some artificial food dyes have been banned, while others remain in use despite suggestions that they too might be harmful. But the makers and users of food dyes argue that the chemicals are safe at current levels of usage. As a result of all this, and in the absence of convincing evidence of their safety, the advocacy group Center for Science in the Public Interest has campaigned since the 1970s to remove food dyes and other chemicals from foods, and has continued to petition the Food and Drug Administration to ban them.

The opposing views complicate the regulatory status of food dyes. But after one clinical trial reported that dyes induce hyperactivity in half the children studied, the British government asked companies to stop using most food colors; the European Union requires a warning notice on many foods made with them.

In the United States, the FDA does not permit artificial food dyes to be used unless the manufacturers can meet safety requirements. But the amounts of these substances in the country’s food supply have greatly increased in recent years — soft drinks, breakfast cereals, frozen desserts and even salad dressings all contain artificial coloring agents. True, the FDA considers a dye to be safe if there is a reasonable certainty that no harm will result from its intended use. But that standard is vague enough to cause concern.

Given the unresolved scientific questions, it is reasonable to ask why artificial colors have to be in foods at all. From the standpoint of manufacturers, such additives are essential for covering up and hiding unattractive colors in processed foods. To the public, red candy seems to taste better than the drab variety. And while natural colors exist, they are less stable or more expensive to produce. But for Nestle to have taken the action that it has, the company must have found substitutes it can live with. And appealing to consumers’ preference for “natural” makes good business sense.

The truth is that whether artificial colors do or do not cause health problems in adults or children, they are there strictly for cosmetic purposes. For that reason alone, getting rid of them is a good idea.

I gave a talk last week at Hastings College in Hastings, Nebraska.

Before I left, Michael Moss, who wrote the New York Times investigative report about Hasting’s USDA animal research facility, mentioned the Kool-Aid museum.

The Kool-Aid museum?

As it happens, I adore museum exhibits devoted to single food items.  The Hastings Museum houses a permanent collection of Kool-Aid historical materials and artifacts.

A Hastings resident, Edwin Perkins, invented this product in 1927.

Kool-Aid, in case this isn’t on your usual shopping list, is a flavored and colored powder that comes in small packets.  You add the 4.6 gram contents—plus one full cup of sugar—to two quarts of water.

What’s in the packets?  I was given a cherry limeade flavor: contains citric acid, maltodextrin, calcium phosphate, vitamin C, natural and artificial flavor, salt, artificial color, red 40, tocopherol [a form of vitamin E], BHA, and BHT (preservatives).

The less said about nutritional value, the better.

But take a look at its corporate history:

• 1953   General Foods buys Kool-Aid
• 1985  Philip Morris buys General Foods and, therefore, Kool-Aid
• 1988  Philip Morris buys Kraft
• 1989  Philip Morris combines Kraft and General Foods to create Kraft General Foods (Kool-Aid is now owned by a cigarette company)
• 1995  Philip Morris names the combined entity Kraft Foods
• 2003  Philip Morris changes its name to Altria (Kool-Aid is still owned by a cigarette company)
• 2007  Philip Morris splits Kraft—and, therefore, Kool-Aid—off as a separate company
• 2012  Kraft splits into two companies, Kraft Foods Group (with Kool-Aid) and Mondelez International
• 2012  Kraft Foods Group cuts a deal with SodaStream International to use Kool-Aid with SodaStream devices

I loved the exhibit, even though you have to go through rooms full of guns to get to it.

The exhibit didn’t mention the Jonestown massacre, the source of the phrase “drinking the Kool-Aid” because Kool-Aid was not involved.

The 2015 Dietary Guidelines Advisory Committee is meeting today by teleconference.

One issue, no doubt, will be the House directive in the appropriations bill (page 50 of this draft):

Dietary Guidelines.—The Committee is concerned that the advisory committee for the 2015 Dietary Guidelines for Americans is considering issues outside of the nutritional focus of the panel. Specifically, the advisory committee is showing an interest in incorporating sustainability, climate change, and other environmental factors and production practices into their criteria for establishing the next dietary recommendations, which is clearly outside of the scope of the panel. The Committee directs the Secretary to ensure that the advisory committee focuses only on nutrient and dietary recommendations based upon sound nutrition science and not pursue an environmental agenda. Should environmental or production factors be included in the panel’s recommendations to USDA and
the Department of Health and Human Services, the Committee expects the Secretary to reject their inclusion in the final 2015 Dietary Guidelines for Americans.

Amazing, how Congress thinks it knows more about nutrition thank nutrition scientists.

Let’s grant that Congress knows what the political fallout will be from these guidelines.

NPR interviewed Kate Clancy, who has been arguing for the need to include environmental considerations in dietary guidelines for years.

In 1986, nutritionist Kate Clancy, then teaching at Syracuse University, co-authored [with Joan Gussow] an article called “Dietary Guidelines for Sustainability.” It was addressed to her colleagues, Clancy says. She wanted them “to take a broader view of what they were advising people to do, with regard to their diet. It wasn’t just nutrients.” She urged them to consider not just what foods contribute to personal health, but also what types of food “contribute to the protection of our natural resources.”

Makes sense, no?

Too bad politics trumps science in this Congress.

NutraIngredients-USA has a special edition on functional foods, those that have something supposedly healthy—vitamins, probiotics, antioxidants, omega-3s, etc—added above and beyond the nutrients naturally present.

I think functional foods are about marketing, not health, but that’s why food companies love them.

From the industry’s perspective, “getting nutritional ingredients into foods requires tackling regulatory hurdles, but food offers a mass market that dwarfs anything possible with supplements.

Here are some of NutrIngredients’ latest developments:

Brazil has just released the final version of its Dietary Guidelines for the Brazilian population in English as well as in Portuguese (I wrote about the draft version in an earlier post).

As explained in the press release (also in English), the guidelines include ten steps to healthy diets:

1. Make natural or minimally processed foods the basis of your diet
2. Use oils, fats, salt, and sugar in small amounts when seasoning and cooking natural or minimally processed foods and to create culinary preparations
3. Limit consumption of processed foods
4. Avoid consumption of ultra-processed products
5. Eat regularly and carefully in appropriate environments and, whenever possible, in company
6. Shop in places that offer a variety of natural or minimally processed foods
7. Develop, exercise and share culinary skills
8. Plan your time to make food and eating important in your life
9. Out of home, prefer places that serve freshly made meals
10. Be wary of food advertising and marketing

Traditionally, families based their diets on natural and minimally processed foods.  The guidelines are based on the actual, traditional dietary patterns of a substantial proportion of the Brazilian population of all ages and classes throughout the country.

Carlos Monteiro, the Brazilian nutrition professor listed as the technical formulator of the guidelines, was in Washington DC last week to speak at a conference on the 2015 Dietary Guidelines.   Monteiro’s speech is here.  Tweets sent during the meeting are here.

I hope everybody listened.

The annual meeting of the Academy for Nutrition and Dietetics, formerly the American Dietetic Association, always provides an incredible exhibit of products from food companies—the latest in dietetic junk food and food company nutritional spin.

Knowing how much I enjoy these things, and that I am working on a book about food advocates and the soft drink industry (Oxford University Press, September 2015), several of my colleagues brought back souvenirs.

Functional foods (with “healthy” ingredients above and beyond what occurs naturally)

• For Keurig brewing machines, a container of Fibersol Cran-Raspberry flavored instant tea mix, with soluble fiber added (is tea really a significant source of soluble fiber?).
• MealEnders.com’s chocolate mint signaling lozenges, “an antidote to overeating.”  If you feel that you are overeating, suck on one: “take control, curb appetite, get results” (if only).
• A 6-ounce can of Kao Nutrition’s black coffee with 270 mg polyphenol (coffee chlorogenic acid), naturally present because the coffee was not brewed at high temperature (well, coffee is a plant extract, after all).

Swag

• A pen with a pull-out section that gives the potassium content of commonly consumed foods (these come in other versions too, apparently).

Soda company propaganda

• A brochure from PepsiCo’s Nutrition Team, HydrateNow.  Gatorade, it points out, is 93% water (and the other 7%, pray tell?.
• A pamphlet from PepsiCo on Calorie Balance: “many things influence your everyday nutrition.  For maintaining a healthy weight, the most important factors are how many calories you eat and the total calories you use up”  (but if those calories happen to be empty?).
• A PepsiCo brochure on Diet Beverages for People with Diabetes (but it still is advertising Pepsi).
• A list of PepsiCo drinks that meet the USDA’s nutrition standards for schools (a long list, alas).
• A scientific paper, “What is causing the worldwide rise in body weight,” sponsored by Coca-Cola (Coke’s answer: lack of physical activity, of course.)
• A poster from the American College of Cardiology, “Striking an energy balance,” sponsored in part by Coca-Cola.   It says: “Drink water or no- or low-calorie beverages” (it does not say you should “Drink less soda”).
• A pamphlet on National School Beverage Guidelines sponsored by Coca-Cola, PepsiCo, Dr Pepper Snapple, and the American Beverage Association:  “The beverage industry committed to bold change and then made it happen.  Working with our school partners, we transformed the beverages available to students” (yes, but it doesn’t explain that public pressure forced them to do this).
• A Coca-Cola pamphlet, Balancing Act.  This gives five easy ways to burn 100 calories: playing soccer 13 minutes, briskly walking 15 minutes, climbing stairs 10 minutes, jumping rope 9 minutes, gardening 19 minutes (based on a 150 lb person).  Funny, it doesn’t mention that one 12-ounce Coke is 140 calories.
• A FamilyDoctor.org pamphlet, Healthy Eating for Kids, from the American Academy of Family Physicians and the American Dietetic Association, distributed with a grant from Coca-Cola.  It lists healthy eating habits—family meals, be active, limit screen time, stay positive, etc (but—surprise—does not suggest that your kid might be healthier not drinking sugar-sweetened beverages).

Treasures, all.  I really love this stuff.  Thanks.
