Here’s the latest collection of 5 studies funded by food companies or trade associations, all with results that favor the sponsor’s interests.  I’ve just reviewed them and found a couple of duplicates, so this is a corrected score.  The correct score is 55 industry-funded studies with positive results vs. 3 with results unfavorable to industry—since mid-March.

I’m particularly interested in the unfavorable category.  If you run across any, please send.

Jejunal Casein Feeding Is Followed by More Rapid Protein Digestion and Amino Acid Absorption When Compared with Gastric Feeding in Healthy Young Men. Joanna Luttikhold, Klaske van Norren, Nikki Buijs, Marjolein Ankersmit, Annemieke C Heijboer, Jeannette Gootjes, Herman Rijna, Paul AM van Leeuwen, and Luc JC van Loon. J. Nutr. 2015; 145:2033-2038 doi:10.3945/jn.115.211615.

• Conclusions: Jejunal feeding of intact casein is followed by more rapid protein digestion and AA absorption when compared with gastric feeding in healthy young men. The greater postprandial increase in circulating EAA concentrations may allow a more robust increase in muscle protein synthesis rate after jejunal vs. gastric casein feeding.
• Funding: Supported by Nutricia Research, Utrecht, Netherlands. J Luttikhold was employed by Nutricia Research; K van Norren is a guest employee of Nutricia Research; and LJC van Loon has served as a consultant for Nutricia Research.  [Note: Nutricia Research is a subsidiary of Danone].

Higher Total Protein Intake and Change in Total Protein Intake Affect Body Composition but Not Metabolic Syndrome Indexes in Middle-Aged Overweight and Obese Adults Who Perform Resistance and Aerobic Exercise for 36 Weeks. Wayne W Campbell, Jung Eun Kim, Akua F Amankwaah, Susannah L Gordon, and Eileen M Weinheimer-Haus. J. Nutr. 2015; 145:2076-2083 doi:10.3945/jn.115.213595.

• Conclusions: In conjunction with exercise training, higher TPro [total protein] promoted positive changes in BC [body composition] but not in MetS [metabolic syndrome] indexes in overweight and obese middle-aged adults. Changes in TPro from before to during the intervention also influenced BC responses and should be considered in future research when different TPro is achieved via diet or supplements.
• Funding:  Supported by the US Whey Protein Research Consortium (to WWC) among others.  WW Campbell was a member of the National Dairy Council Whey Protein Advisory Panel while the research was being conducted.

Intense Sweeteners, Appetite for the Sweet Taste, and Relationship to Weight Management.  France Bellisle.  Current Obesity Reports March 2015, Volume 4, Issue 1, pp 106-110 10.1007/s13679-014-0133-8

• Conclusion: While many of the existing studies cannot identify any causal links between use of LES [artificial, low-energy sweeteners] and appetite for sweetness, randomized trials in children and adults suggest that use of LES tends to reduce rather than increase the intake of sugar-containing foods and to facilitate, rather than impair, weight loss.
• Conflict: Parts of [this study] are extracted from a non-published document for which the author received an honorarium from the International Sweeteners Association (ISA).  France Bellisle is a member of the Scientific Advisory Board for General Mills and has received travel reimbursement and honoraria for contributions in scientific congresses from Mondelez, ISA, and General Mills.

Impact of cocoa flavanol intake on age-dependent vascular stiffness in healthy men: a randomized, controlled, double-masked trial.  Christian Heiss & Roberto Sansone & Hakima Karimi & Moritz Krabbe & Dominik Schuler & Ana Rodriguez-Mateos & Thomas Kraemer & Miriam Margherita Cortese-Krott & Gunter G. C. Kuhnle & Jeremy P. E. Spencer & Hagen Schroeter & Marc W. Merx & Malte Kelm & for the FLAVIOLA Consortium, European Union 7th Framework Program.  AGE (2015) 37: 56 DOI 10.1007/s11357-015-9794-9

• Conclusion: CF [cocoa flavanol] intake reverses age-related burden of cardiovascular risk in healthy elderly, highlighting the potential of dietary flavanols to maintain cardiovascular health.
• Funding: …Additional funding was provided by an unrestricted grant by MARS, Inc…MARS, Inc. provided the standardized test drinks used in this investigation. HS is employed by MARS, Inc., a member of the FLAVIOLA research consortium and a company engaged in flavanol research and flavanol-related commercial activities.

Cocoa flavanol intake improves endothelial function and Framingham Risk Score in healthy men and women: a randomised, controlled, double-masked trial: the Flaviola Health Study.  Roberto Sansone, Ana Rodriguez-Mateos , Jan Heuel, David Falk, Dominik Schuler, Rabea Wagstaff, Gunter G. C. Kuhnle, Jeremy P. E. Spencer, Hagen Schroeter, Marc W. Merx, Malte Kelm and Christian Heiss for the Flaviola Consortium, European Union 7th Framework Program.  British Journal of Nutrition, September 9, 2015. doi:10.1017/S0007114515002822.

• Conclusion: In healthy individuals, regular CF [cocoa flavanol] intake improved accredited cardiovascular surrogates of cardiovascular risk, demonstrating that dietary flavanols have the potential to maintain cardiovascular health even in low-risk subjects.
• Funding: Additional funding was provided…through an unrestricted grant by MARS Inc. MARS Inc. also provided the standardised test drinks used in this investigation… H. S. provided test drinks on behalf of Mars Inc… H. S. is employed by MARS Inc., a member of the Flaviola research consortium and a company engaged in flavanol research and flavanol-related commercial activities. [The conflict statement also discloses that MARS employee H.S. shared responsibility for designing the study, writing the paper, and approving the final content].
• Comment: Lest the implicit (but never stated directly) “eat more chocolate” message of these studies be missed, Mars sent out a press release: “Cocoa flavanols lower blood pressure and increase blood vessel function in healthy people.”

On Fridays, I often post books I’ve blurbed or liked.

Today, it’s my turn.  I can’t resist posting the blurbs for Soda Politics: Taking on Big Soda (and Winning).   

The blurbs:

• “The soda industry is a powerful economic operator. Economic power readily translates into political power. Soda Politics is exactly the kind of carefully-researched investigative reporting needed to open the eyes of the public and parliamentarians to the health hazards of what is, as the author rightly notes, essentially liquid candy in a bottle.” –Dr. Margaret Chan, Director-General, World Health Organization
• “No book in history has so completely laid bare the soda scourge that touches every corner of the world. Marion Nestle shows how this happened, its impact on human health and well-being, who the players are, and, most importantly, what might be done. This is the right book at the right time.” –Dr. Kelly Brownell, Dean, Sanford School of Public Policy, Duke University
• “Marion Nestle is one of the greatest muckrakers of our time, and what she does is vitally important-for our health, our environment, and for future generations. Here, she wages war against the soda titans with such piercing clarity and so many irrefutable truths that all other arguments crumble.” –Alice Waters, Founder and Proprietor of Chez Panisse
• “Comprehensive and well-written, this book will help frame a thoughtful public policy debate about nutrition and the societal impacts and costs of obesity.” –Ann M. Veneman, Former US Secretary of Agriculture and Former Executive Director of UNICEF
• “What happens when the food industry’s most insightful critic turns her sights on soda? This razor-sharp, fun to read, plan-of-battle for one of the greatest public health fights of our time. Big soda may have all the money, but those who would enter this fray, as we all should, now have their champion.” –Michael Moss, Author of Salt Sugar Fat: How the Food Giants Hooked Us
• “For decades, soda companies have amassed fortunes off drinks that are making us sick. It took someone like Marion Nestle to cut through the spin and uncover the high cost of cheap sodas.” –Robert Kenner, Director/Producer, Food Inc. and Merchants of Doubt
• “Long recognized as an important and informed voice in our national and international discussions on nutrition and health, Marion Nestle has written another book that will keep us talking. With an impressive combination of scholarship and advocacy, Dr Nestle takes an unflinching look at the soda industry, its products and the impact on health. Soda Politics deserves the attention of the public and policy makers, and should make us all think more carefully about choices we can make to improve health and well-being.”–Margaret Hamburg, M.D., Former Commissioner, U.S. Food and Drug Administration 

The book officially comes out October 5, but Oxford University Press is already shipping it to preorders and Amazon starts shipping it next week.

Enjoy!

Since mid-March, I’ve been collecting research studies funded by food companies or trade associations, and dividing them into those that come out with results favorable to the sponsor (50 so far–this is a corrected number) and those that do not (as of today, 3).

As always, if you run across others, please send.

A reader, Cole Adam, sent me this study on dark chocolate funded by a Finnish company that makes chocolate products.

Dark chocolate and reduced snack consumption in mildly hypertensive adults: an intervention study.  Raika Koli, Klaus Köhler, Elina Tonteri, Juha Peltonen, Heikki Tikkanen and Mikael Fogelholm.  Nutrition Journal 2015, 14:84  doi:10.1186/s12937-015-0075-3

• Results: Daily consumption of dark chocolate had no effects on 24 h blood pressure, resting blood pressure…or arterial stiffness.  Weight was reduced by 1.0 ± 2.2 kg during the control (reduced snack only) period, but was unchanged while eating chocolate (p < 0.027 between the treatments).
• Conclusion:  …inclusion of 49 g dark chocolate daily as part of a diet of mildly hypertensive participants had no significant effects on cardiovascular risk factors during 8 wks.  Apart from a small effect on body weight (dark chocolate seemingly prevented a slight decrease in body weight during the control period), no other negative effects were observed.
• Funding:  This work was funded by Oy Karl Fazer Ab. Authors declare no competing interests regarding this study.  [Oy Karl Fazer Ab sells bakery, biscuit, and confectionery products in Finland, Sweden, Estonia, Latvia, Lithuania, Norway, Denmark, Russia, and internationally]

Several points to note about this study:

• Eating 49 grams (just under 2 ounces) of dark chocolate a day may be fun, but it is not going to reduce your blood pressure.
• Eating 49 grams of dark chocolate a day makes weight loss more difficult.
• The authors do not view corporate funding as introducing competing interests.  OK.  Maybe not in this case, but this is a rare exception.

Another reader, who prefers to remain anonymous, sent this one:

Milk intake is not associated with low risk of diabetes or overweight-obesity: a Mendelian randomization study in 97,811 Danish individuals.  Helle KM Bergholdt, Børge G Nordestgaard, and Christina Ellervik.  Am J Clin Nutr 2015;102:487–96. 

• Conclusions: High milk intake is not associated with a low risk of type 2 diabetes or overweight-obesity, observationally or genetically via lactase persistence.  The higher risk of type 2 diabetes in   individuals without milk intake likely is explained by collider stratification bias.
• Conflict: HKMB’s PhD project was partly funded by the Research Unit at Naestved Hospital, the Danish Dairy Research Foundation, and the Regional Research Unit in Region Zealand. [The population studies were funded by a long list of government agencies, health organizations, and foundations].
• Comment: This study says that high milk intake is associated with a higher risk of type 2 diabetes, although it explains it away.  The Danish dairy industry paid for part of the first author’s dissertation research.  It looks like most of the funding came from independent sources, so this one is a bit of a stretch, but to be super scrupulous let’s count it as industry-funded.

NOTE: All three “negative” studies I’ve posted since March were funded by international food companies (the previous one was funded by the Danish Dairy Research Foundation).

I thought we all needed a break from the debates over funding of science by the GMO industry and the organic industry.

How’s this for supermarket creativity!

Maybe if the Soviets had used a Tomahawk instead of a sickle?

Sunday’s New York Times story on academic conflicts of interest focused on scientists with financial ties to Monsanto.  The ties were revealed by open-records requests for e-mails and other information.

The Times was not the only one to make these requests.  U.S. Right to Know, a group devoted to investigating Big Food and its front groups had already done so.  U.S. Right to Know is funded primarily by the Organic Consumers Association, a national grassroots network advocating for organics, sustainability, and food safety—but against GMOs.

U.S. Right to Know rightfully takes credit for establishing the basis of the Times’ story.  It sent open-records requests to scientists working for public institutions who seemed likely to have financial ties to Monsanto.  Bingo.  Some of the e-mails revealed such ties.*

But should government-funded scientists be subjected to open records requests?  Couldn’t these requests amount to open season on academics—a modern-day version of witchhunts?  This question is now under active debate (and see comments on my previous post).

While these debates are raging, here is one aspect of this story that the New York Times did not tell.

Earlier this month, Paul Thacker and my NYU colleague Charles Seife, wrote a piece for PLoS [Public Library of Science] Blogs arguing that Freedom of Information Act (FOIA) requests “for personal correspondence are not just appropriate, but crucial to ensuring transparency.”   They argue that the benefits of transparency outweigh the costs.

But transparency laws remain a fundamental tool for monitoring possible scientific misbehavior. And it would be a mistake to believe that scientists should not be subject to a high level of outside scrutiny. So long as scientists receive government money, they are subject to government oversight; so long as their work affects the public, journalists and other watchdogs are simply doing their jobs when they seek out possible misconduct and questionable practices that could threaten the public interest.

Thacker and Seife explain:

Last week, Nature reported that the University of Florida had provided them with emails that U.S. Right to Know had FOIA’d on one of their researchers…the [Nature] story noted that the researcher has received money from Monsanto to fund expenses incurred while giving educational talks on GMOs.  The article also noted that the PR Firm Ketchum had provided the scientist with canned answers to respond to GMO critics, although it is unclear if he used them [the Times story says he did but now regrets it].

The article does not report that the scientist has repeatedly denied having a financial relationship with Monsanto. The article also does not report on an email titled “CONFIDENTIAL: Coalition Update” from the researcher to Monsanto in which the scientist advised Monsanto on ways to defeat a political campaign in California to require labeling of GMO products.

Some readers of PLoS were outraged that this online journal would publish an article supporting open-records requests of scientists (see, for example, this from the American Council on Science and Health).

Here’s where things get interesting.

PLoS responded to the criticism by, of all things, retracting the article.

Seife and Thacker explained their views in an op-ed in the Los Angeles Times.

If the public pays your salary, citizens have the right — within limits — to see what you’re doing. That’s the principle at the core of the federal Freedom of Information Act and of the many similar state freedom of information laws… “snooping” on scientists’ inboxes by journalists, watchdogs and government officials has revealed significant problems that would never have come to light via other means.

That, of course, is the basis of the New York Times’ exposé of Monsanto’s funding of scientists to testify on the company’s behalf to reporters, Congress, and the public.

Bottom line: Because industry-funded science and scientists almost invariably provide data and testimony that favors the sponsors interests, the press and public need to know about sponsorship.

One more comment:  A substantial body of literature exists on industry sponsorship of science, particularly on the effects of pharmaceutical industry funding of medical professionals.  Conflicts-of-interest researchers conclude that such conflicts are generally unconscious, unintentional, and unrecognized by participants.  The remedy is increased government spending for research, an unlikely possibility these days.  This means journalists will be kept busy exposing the many problems that arise when scientists take industry funding.

*The documents collected by the New York Times

• David Shaw
• Bruce Chassy
• Kevin Folta

Additions:

• Note: My previous post on organic-industry funding gives the link to the e-mails for Charles Benbrook
• Jonathan Latham provides further details on GMO public relations efforts

Today’s New York Times has another front-page (and on the inside, full-page) story on the food industry’s financial relationships with academic scientists.

The article describes how Monsanto funded scientists to lobby for GMOs in Washington (I will say more about this in a subsequent post).

But, as is clear from this report, the organic industry is doing much the same.

The Times based the story on e-mails it collected through open records law requests (the equivalent of Freedom of Information Act requests for federal documents).

And surprise!  I turn up in Charles Benbrook’s.  I learned this from checking Twitter yesterday.

I’m only on the B-list for influencing public opinion?  Alas.

It seems that Charles Benbrook, a strong proponent of organics (as am I), was working with (for?) the Organic Valley Cooperative on a public relations campaign to promote his organics-funded study demonstrating that organic milk has a healthier fatty acid profile than conventional milk.

I vaguely remember him contacting me about the study, but I didn’t write anything about it.  It appeared to be an industry-funded study with results favoring the sponsor’s interests—much as, in this case, I sympathize with those interests.

A few months later, I did write write about another conflicted organic study:

The study is not independently funded….This study is another example of how the outcome of sponsored research invariably favors the sponsor’s interests.  The paper says “the  [Sheepdrove] Trust  had  no  influence  on  the  design  and management of the  research  project  and  the  preparation  of publications  from the project,” but that’s exactly what studies funded by Coca-Cola say.  It’s an amazing coincidence how the results of sponsored studies almost invariably favor the sponsor’s interests.  And that’s true of results I like just as it is of results that I don’t like.

Benbrook has been criticized recently for not fully disclosing his ties to the organic industry.  Even if he had, disclosure is not enough.

The bottom line: Conflicted studies are conflicted, no matter who pays for them.

Leanne Brown.  Good and Cheap: Eat Well on $4 / Day.  Workman, 2015.

Leanne Brown is a graduate of our food studies program at New York University who, while in graduate school, became concerned about the plight of SNAP (food stamp) recipients who must feed their families on an average of $4 per day.

She wrote this book for them, first as a class project, then as an online gift, free for the taking.

It was downloaded 700,000 times.

Then she went to a Kickstarter campaign to self-publish the book.  At some point Workman picked it up.

It’s won an award from the International Association of Culinary Professionals and a place for Leanne in Forbes 30 under 30 for 2015.

The book has truly delicious recipes.  It starts with tips useful for anyone on a food budget.

I’m proud of what she’s accomplished.  The book is beautifully photographed, the recipes are terrific, and every time a copy is sold, Workman will donate another one to someone who needs it.

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 Trial.  Hannah 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.
