Five more industry-sponsored studies with results favorable to the sponsor. The score since mid-March: 95:9

Systematic Review of Pears and Health. Holly Reiland, BS Joanne Slavin, PhD, RD.  Nutrition Today November/December 2015 – Volume 50 – Issue 6 – p 301–305.  doi: 10.1097/NT.0000000000000112.  

  • Conclusions: Animal studies with pears suggest that pears may regulate alcohol metabolism, protect against ulcers, and lower plasma lipids. Human feeding studies with pears have not been conducted. In epidemiological studies, pears are combined with all fresh fruits or with apples, because they are most similar in composition. The high content of dietary fiber in pears and their effects on gut health set pears apart from other fruit and deserves study.
  • Funding: The authors received a grant from USA Pears in the past. The authors provided their own funding to allow this article to publish as Open Access.
  • Comment: Pears are a great fruit but the marketing purpose of this study is evident from this press release from the Pear Bureau Northwest: “While the body of evidence connecting pear intake and health outcomes is still limited, USA Pears has been contributing to research efforts by commissioning independent studies to learn and affirm the heath attributes of pears. Visit www.usapears.org for additional pear research, nutrition resources and recipes.”

Whole Grain Intakes in the Diets Of Malaysian Children and Adolescents – Findings from the MyBreakfast Study.  Norimah AK , H. C. Koo, Hamid Jan JM, Mohd Nasir MT, S. Y. Tan, Mahendran Appukutty, Nurliyana AR, Frank Thielecke, Sinead Hopkins, M. K. Ong, C. Ning, E. S. Tee.  PLoS ONE 10(10): e0138247. doi:10.1371/journal.pone.0138247

  • Conclusion: Whole grain is consumed by only a minority of Malaysian children and adolescents and even among consumers, intakes are well below recommendations. Efforts are needed to firstly understand the barriers to whole grain consumption among Malaysian children in order to design effective health promotion initiatives to promote an increase in whole grain consumption.
  • Funding: The Nutrition Society of Malaysia received an unrestricted research grant from Cereal Partners Worldwide, Switzerland and Nestleé R&D Center, Singapore. This financial support was provided in the form of salaries for authors but the funders did not have any additional role in the study design, data collection and analysis or decision to publish. Frank Thielecke was an employee of Cereal Partners Worldwide at the time this study was conducted. He now works for Nestec SA. Sinead Hopkins is employed by Cereal Partners Worldwide (CPW), Switzerland and Moi Kim Ong and Celila Ning are employed by Nestleé R&D Center, Singapore….Nestlé and Cereal Partners Worldwide have a commercial interest in breakfast cereals.
  • Comment: I learned about this study from a comment on Retraction Watch, which reported that PLoS One had filed a correction to the funding section.  The correction says that the salaries were for research assistants, not authors.

Walnuts Consumed by Healthy Adults Provide Less Available Energy than Predicted by the Atwater Factors.  David J Baer*, Sarah K Gebauer, and Janet A Novotny. J Nutrition First published November 18, 2015, doi: 10.3945/​jn.115.217372.

  • Conclusion: Consistent with other tree nuts, Atwater factors overestimate the metabolizable energy value of walnuts. These results could help explain the observations that consumers of nuts do not gain excessive weight and could improve the accuracy of food labeling.
  • Funding: This research was funded by the USDA and the California Walnut Commission… DJ Baer was funded by the USDA and the California Walnut Commission.

Cardiorespiratory Fitness, Body Fatness, and Submaximal Systolic Blood Pressure Among Young Adult WomenPrasad Vivek Kumar, Drenowatz Clemens, Hand Gregory A., Lavie Carl J., Sui Xuemei, Demello Madison, and Blair Steven N.  Journal of Women’s Health, 2015 ahead of print. doi:10.1089/jwh.2015.5307.

  • Conclusion: CRF, BF%, and BMI seem to have critical roles in determining SSBP with CRF and BF% being more potent at lower intensity exercise, whereas BMI was more strongly associated at higher intensity exercise.
  • Funding for this project was provided through an unrestricted grant from The Coca-Cola Company. The sponsor played no role in the study design, data collection, analysis, and interpretation, or preparation and submission of this article. The authors thank the Energy Balance staff and study participants for their contributions. No competing financial interests exist. 
  • Comment: This is one of the papers produced by participants in the now defunct Global Energy Balance Network formerly sponsored by Coca-Cola.

Does low-energy sweetener consumption affect energy intake and body weight? A systematic review, including metaanalyses, of the evidence from human and animal studies. PJ Rogers, PS Hogenkamp, C de Graaf , S Higgs , A Lluch , AR Ness , C Penfold , R Perry , P Putz , MR Yeomans and DJ Mela.  International Journal of Obesity advance online publication, 10 November 2015; doi:10.1038/ijo.2015.177

  • Conclusion¨The preponderance of evidence from all human randomized controlled trials indicates that LES [low-energy sweeteners] do not increase EI [energy intake] or BW [body weight], whether compared with caloric or non-caloric (for example, water) control conditions. Overall, the balance of evidence indicates that use of LES in place of sugar, in children and adults, leads to reduced EI and BW, and possibly also when compared with water.
  • Conflict: This work was conducted by an expert group of the European branch of the International Life Science Institute (ILSI Europe). The expert group received funding from the ILSI Europe Eating Behaviour and Energy Balance Task Force. Industry members of this task force are listed on the ILSI Europe website at www.ilsi.eu.
  • Comment: ILSI is funded by food companies.

Arsenic in rice: another food safety worry?

I am often asked about the potential dangers of arsenic in rice.  As with all such questions, I start with the FDA.

The FDA says the amounts of arsenic it finds in foods do not pose a risk at current levels of consumption.  Brown rice, it finds, has levels of arsenic much higher than those in white rice.

Consumer Reports also tested rice samples.  It recommends against feeding rice cereals to children.  It calls on the FDA to set standards for arsenic levels in rice products.  These, according to the tests, vary widely.  Basmati rice from California, India and Pakistan and U.S.-grown sushi rice are “better choices.”  Just one serving of rice cereal or rice pasta could put a child over CR’s recommended weekly limit

On this basis, Congresswoman Rosa DeLauro (D-CT) introduced legislation— The R.I.C.E (Reducing food-based Inorganic Compounds Exposure) Act— to limit the amount of inorganic arsenic, the most toxic form of arsenic in rice foods.  The act would require the FDA to set limits on arsenic in rice.

Politico reported that the US Rice Federation questioned the science behind the Consumer Reports story:

Arsenic in our food supply is a challenging, yet unavoidable, situation which is why we support the FDA studying the issue carefully,” said Betsy Ward, president and CEO of the USA Rice Federation.  “But CR’s new consumption recommendations aren’t supported by any science that we’ve seen.”

How does arsenic get into rice?  Lots of ways, apparently: naturally occurring, but also from arsenic pesticides that persist in soil.  The flooding makes rice especially susceptible.

What to do while waiting for a resolution to safety questions?  Prepare rice in a coffee percolator says a recent study.  This flushes out a lot of the arsenic.

And everything in moderation, of course.

Catching up on food nanotechology

Every now and then something reminds me about food nanotechnology, the use of molecular size nanoparticles to whiten or improve the safety or shelf life of processed foods (see previous posts on the topic).

What brought this on is a recent report from Australia that sounds all too familiar.  Friends of the Earth commissioned tests and found “nanoparticles of titanium dioxide and silica in 14 popular products, including Mars’ M&Ms, Woolworths white sauce and Praise salad dressing.”  Australian regulators, however, have denied that nanoparticles are in use “because no company had applied for approval.”

Last year, Friends of the Earth did the same in America.  Its report, “Tiny Ingredients Big Risks,” documents nanomaterials in more than 90 food products, among them Jet Puffed Marshmallows, Trix Cereal and Nestle Original Coffee Creamer.

Nanoparticles are really small (10-9 meters, or one millionth of a millimeter).  How they work and what they might do to the human body is greatly in need of research.

The FDA’s guidance to industry—nonbinding and, in my opinion, not particularly helpful—says nanoparticles are safe in foods but that companies using them should let the FDA know about it.

It is prudent practice for you to do so, particularly when the manufacturing process change involves emerging technologies, such as nanotechnology…The consequences (to consumers and to the food industry) of broadly distributing a food substance that is later recognized to present a safety concern have the potential to be significant…FDA does not categorically judge all products containing nanomaterials or otherwise involving application of nanotechnology as intrinsically benign or harmful. Rather, for nanotechnology-derived and conventionally-manufactured food products alike, FDA considers the characteristics of the finished product and the safety of its intended use.

Are they really safe?  Nobody knows, leaving much room for unease, as Twilight Greenaway pointed out in Grist in 2012.  Her Grist colleague Tom Philpott wrote about this question even earlier—in 2010: “The strategy seems to be: release into the food supply en masse first; assess risks later (if ever).”

This is not reassuring

Web MD suggests that “while researchers are still sorting it out, avoid heavily processed foods, and read labels if you’re concerned.”

Good advice, and another reason to avoid heavily processed foods.

Five more industry-funded studies with predictable results. Score since March: 52:1

Energy flux: staying in energy balance at a high level is necessary to prevent weight gain for most people.  Gregory A Hand, Robin P Shook, James O Hill, Peter R Giacobbi, and Steven N Blair.   Expert Rev. Endocrinol. Metab.  Early online, 1–7 (2015)

  • Conclusion: Maintaining energy balance at a higher caloric intake and expenditure should be a more successful long-term strategy for weight maintenance than reduced consumption or extreme caloric restriction at a low level of energy expenditure (a low energy flux) and improve intervention effectiveness for sustainable methods for body weight stability. [Implication: eat more to lose weight?]
  • Funding: GA Hand received non-restricted research funding and travel grant from The Coca Cola Company and a travel grant from International Life Sciences Institute. RP Shook received a travel grant from the Coca Cola Company. JO Hill received research support from the Coca Cola Company and the American Beverage Association. JO Hill is on the advisory board for McDonalds, General Mills, Curves, Consumer Goods Association, Calorie Control Council, International Food Information Council and McCormick Science Institute. JO Hill is a consultant for Walt Disney, has equity in Gelesis and Active Planet and is on the Board of Directors for International Life Sciences Institute and Livewell Colarado. SN Blair is the principal investigator on projects supported by unrestricted research grants from The Coca Cola Company to the University of South Carolina.
  • Comment: Some of these investigators were among those highlighted in the New York Times article revealing Coca-Cola’s funding of research demonstrating that physical activity is more important than diet in weight maintenance.

Reducing obesity will require involvement of all sectors of society. James O. Hill, John C. Peters and Steven N. Blair. Obesity Volume 23, Issue 2, February 2015, Page: 255.

  • Conclusion: If the physical inactivity industry could commit to increasing physical activity by 78 calories a day per person, we would begin seeing some real success…we need innovative thinking, recognition that both food and physical activity are important, and open minds about how to engage all of society in making changes.
  • Disclosure: Dr. Hill reports personal fees from Coca-Cola, personal fees from McDonald’s, grants from American Beverage Association, personal fees from Walt Disney Company, personal fees from General Mills, personal fees from Calorie Control Council, other from International Life Sciences Institute, and other from Retrofit outside the submitted work. In addition, Dr. Hill has a patent Energy Gap issued. Dr. Blair reports grants from Technogym and grants from Coca-Cola. Dr. Peters has no competing interests to disclose.
  • Comment: same investigators as in previous example.

Instant Oatmeal Increases Satiety and Reduces Energy Intake Compared to a Ready-to-Eat Oat-Based Breakfast Cereal: A Randomized Crossover Trial. Candida J. Rebello MS, RD, William D. Johnson PhD, Corby K. Martin PhD, Hongmei Han MS, Yi-Fang Chu PhD, Nicolas Bordenave PhD, B. Jan Willem van Klinken MD, PhD, Marianne O’Shea PhD & Frank L. Greenway MD.  Journal of the American College of Nutrition Published online: 14 Aug 2015.  DOI:10.1080/07315724.2015.1032442

  • Conclusion: Oatmeal suppresses appetite, increases satiety, and reduces energy intake compared to the RTEC [ready-to-eat cereal].
  • Funding: The trial was funded by Quaker Oats Center of Excellence and PepsiCo R&D Nutrition….

Impact of equol-producing capacity and soy-isoflavone profiles of supplements on bone calcium retention in postmenopausal women: a randomized crossover trial.  Jessica W Pawlowski, Berdine R Martin, George P McCabe, Linda McCabe, George S Jackson, Munro Peacock, Stephen Barnes, and Connie M Weaver. Am J Clin Nutr September 2015 vol. 102 no. 3 695-703.

  • Conclusion: Soy isoflavones, although not as potent as risedronate [a drug used to treat osteoporosis], are effective bone-preserving agents in postmenopausal women regardless of their equol-producing status, and mixed isoflavones in their natural ratios are more effective than enriched genistein.  [Equol is an isoflavone produced by intestinal bacteria]
  • Conflicts: CMW is on the scientific advisory board of Pharmavite [the maker of SoyJoy]. SB has a US patent on the use of conjugated isoflavones and the prevention of osteoporosis.

Agave Inulin Supplementation Affects the Fecal Microbiota of Healthy Adults Participating in a Randomized, Double-Blind, Placebo-Controlled, Crossover TrialHannah D Holscher, Laura L Bauer, Vishnupriya Gourineni, Christine L Pelkman, George C Fahey, Jr., and Kelly S Swanson. J. Nutr. 2015; 145:2025-2032 doi:10.3945/jn.115.217331

  • Conclusions: Agave inulin supplementation shifted the gastrointestinal microbiota composition and activity in healthy adults. Further investigation is warranted to determine whether the observed changes translate into health benefits in human populations.  [Note: Agave inulin is a prebiotic, a fiber that can be metabolized by intestinal bacteria.  The study reports enrichment of fecal Bifidobacterium (the good kind)].
  • Funding: Supported in part by Global Nutrition R&D, Ingredion Incorporated, Bridgewater, NJ.  V Gourineni and CL Pelkman are employees of Global Nutrition R&D, Ingredion, Incorporated.  [Ingredion manufactures prebiotic fibers]

As always, please send examples, particularly of industry-funded studies that do not produce results in the sponsor’s interest.

The food industry’s undue influence on the American Society for Nutrition

I’m catching up with events I missed while offline in Cuba.  Here’s one: Michele Simon’s new report:

The American Society for Nutrition (ASN) is the leading organization for physicians and scientists who conduct nutrition research.  I’ve been a member for years and have long fretted about the ASN’s too-cozy relationships with food company sponsors (for example, see my posts on the ill-fated Smart Choices campaign and on a recent ASN annual meeting).

Simon has now done for the ASN what she previously did for the American Academy of Dietetics.

A few of her findings:

  • Of the 34 scientific sessions at ASN’s annual meeting, 6 were supported by PepsiCo, and others were supported by the Egg Nutrition Center, Kellogg, DuPont Nutrition and Health, Ajinomoto, and the National Dairy Council.
  • The International Life Sciences Institute (a front group for Big Food and Big Pharma) sponsored a session on low-calorie sweeteners; speakers included a scientific consultant for Ajinomoto, which produces aspartame.
  • For $35,000, junk food companies can sponsor the hospitality suite at the annual meeting, where corporate executives socialize with nutrition researchers.
  • ASN published an 18- page defense of processed food that consists of numerous talking points for the junk food industry, such as “There are no differences between the processing of foods at home or at a factory.”
  • ASN opposes an FDA proposed policy to include added sugars on the Nutrition Facts panel, at a time when excessive sugar consumption is causing a national public health epidemic.

I’m quoted in the report:

I think it’s important that professional societies like ASN promote rigorous science and maintain the highest possible standards of scientific integrity. Research and education about food and nutrition are easily influenced by funding from food companies but such influence often goes unrecognized. This means that special efforts must be taken to avoid, account for, and counter food industry influence, and organizations like ASN should take the lead in doing so.

The report has been well covered by the media:

Relations between nutrition scientists and food companies worry me.  Here’s another example: Portuguese nutritionists have produced an e-book extolling the virtues of cereal-based drinks.  The book is sponsored by Nestlé (the company, not me).  Nestlé, no surprise, is the market leader for these products in Portugal.  I thank Vladimir Pekic of BeverageDaily.com for finding this one.

Is breakfast necessary?

With apologies for how silly this question might sound, Whitney Kimball of Hopes&Fears asked, “Is breakfast the most important meal of the day?”

Here’s what I told her:

The question isn’t silly at all, although I always laugh when I hear it. That is because I am publicly outed as not a breakfast eater—at least not first thing in the morning. I don’t usually start getting hungry until 11 or so and rarely eat before then. Coffee, yes. Solid food, later please. The idea that early eating is essential makes perfect sense for farm laborers and small children. Whether it matters for normal, sedentary adults is a different question.

Many—if not most—studies demonstrating that breakfast eaters are healthier and manage weight better than non-breakfast eaters were sponsored by Kellogg or other breakfast cereal companies whose businesses depend on people believing that breakfast means ready-to-eat cereal.  Independently funded studies tend to show that any eating pattern can promote health if it provides vegetables and fruits, balances calories, and does not include much junk food. For most people, when you eat matters far less than how much you eat.  If you wake up starving, by all means eat an early breakfast. If not, eat when you are hungry and don’t worry about it.   Kids who won’t have access to decent food in school may well be better off fed breakfast at home and surely will learn better if their stomachs aren’t growling.
