Currently browsing posts about: Sponsored-research

I’ve managed to collect another five industry-sponsored studies with results that the funder must love, bringing the total to 75 since mid-March.  As always, please keep your eye out for industry-funded studies that are contrary to the sponsor’s interests.  I’ve only managed to find 6 so far.

Dairy products consumption and metabolic syndrome in adults: systematic review and meta-analysis of observational studies.  Guo-Chong Chen, Ignatius M. Y. Szeto, Li-Hua Chen, Shu-Fen Han, Yan-Jie Li, Rina van Hekezen, and Li-Qiang Qin^.. Science Reports. 2015; 5: 14606. Published online 2015 Sep 29. doi:  10.1038/srep14606

• Conclusions: Higher dairy consumption significantly reduced MetS [metabolic syndrome] by 17% in the cross-sectional/case-control studies…and by 14%…in cohort studies….Our findings suggest an inverse dose-response relationship between dairy consumption and risk of MetS.
• Funding: This study was supported by Yili Innovation Center, Inner Mongolia Yili Industrial Group Co., Ltd. The funding source had no role in the design or conduct of the study; collection, management, analysis, or interpretation of the data; or preparation, review, or approval of the manuscript.
• Comment: The Yili Group is a privately owned Chinese company headquartered in Hohhot, Inner Mongolia, engaged in processing and manufacturing milk products, including ice-cream, powdered milk, milk tea powder, sterilized milk and fresh milk.

Energy compensation following consumption of sugar‑reduced products: a randomized controlled trial.  Oonagh Markey · Julia Le Jeune · Julie A. Lovegrove  Eur J Nutr First online: 09 September 2015 DOI 10.1007/s00394-015-1028-5.

• Conclusion: Consumption of sugar-reduced products, as part of a blinded dietary exchange for an 8-week period, resulted in a significant reduction in sugar intake. Body weight did not change significantly, which we propose was due to energy compensation.
• Conflict of interest. This work was supported by Sugar Nutrition UK; however, the sponsor had no input into the study hypothesis and design, data analysis and interpretation.
• Comment: It is in the interest of sugar trade associations to demonstrate that eating less sugar has no effect on body weight. 

Trends in Sugar-Sweetened Beverages: Are Public Health and the Market Aligned or in Conflict?  William Shrapnel.  Nutrients 2015, 7(9), 8189-8198; doi:10.3390/nu7095390.

• Conclusions: drinks containing non-nutritive sweeteners enable the “small change” in health behaviour that individuals are willing to consider…Among those who currently consume carbonated beverages, the “small change” involved in moving from a sugar-sweetened beverage to a similar sugar-free beverage appears to be one that some consumers are willing to accept.  Facilitating this change may be a more productive public health strategy than advocacy for taxation of sugar-sweetened beverages.
• Author disclosure: William Shrapnel was paid a consultancy fee by the Australian Beverage Council Ltd. to prepare this paper…The authors declare no conflict of interest.

Dietary Intervention for Overweight and Obese Adults: Comparison of Low-Carbohydrate and Low-Fat Diets. A Meta-Analysis.  Jonathan Sackner-Bernstein, David Kanter,  Sanjay Kaul.  PLoS One, October 20, 2015.  DOI: 10.1371/journal.pone.0139817.

• Conclusions: In conclusion, this trial-level meta-analysis of 17 randomized controlled trials shows that both LoCHO and LoFAT diets are effective in reducing weight. However, LoCHO diet appears to achieve greater weight loss and reduction in predicted risk of ASCVD [atherosclerotic cardiovascular disease] events compared with LoFAT diet. On the basis of these results, we suggest that dietary recommendations for weight loss should be revisited to consider this additional evidence of the benefits of LoCHO diets.
• Funding: The study was supported by Atkins Nutritionals….Jonathan Sackner-Bernstein owns and may receive compensation from ExVivos, LLC. ExVivos, LLC provided payment to authors (DK and SK) for their role as contractors to ExVivos, LLC.
• Comment: ExVivos, LLC has one employee—Jonathan Sackner-Bernstein.  Atkins Nutritionals markets a low-carbohydrate diet plan.

Breast-feeding and postpartum maternal weight trajectories.  Laura Mullaney, Amy C O’Higgins, Shona Cawley, Rachel Kennedy, Daniel McCartney and Michael J Turner.

• Conclusions: There are many reasons why breast-feeding should be strongly promoted but we found no evidence to support postpartum weight management as an advantage of breast-feeding.
• Financial support: This project was supported by the UCD Centre for Human Reproduction and was partially funded by an unlimited educational grant from Danone Nutricia Early Life Nutrition for the first author.
• Comment: Food companies often provide scholarships for doctoral research.  This particular arrangement raises some tough questions: Should dissertation research supervisors allow their students to accept such funding?  Or does accepting such an award run the risk of compromising the integrity of the student’s work?

Do sugar-sweetened beverages increase the risk of high blood pressure?

Yes, says this study, which was conducted by investigators who accept research funding from Coca-Cola and the Calorie Control Council (a trade association for companies that make or use artificial sweeteners).  But the study itself was funded by independent government agencies or health associations in Canada.

I’m counting it in the category of studies with results unfavorable to the food industry sponsors.

This brings the score to 70 industry-funded studies since mid-March with results favorable to the sponsor, to 6 with unfavorable results.

Sugar-sweetened beverage consumption and incident hypertension: a systematic review and meta-analysis of prospective cohorts.  Viranda H Jayalath, Russell J de Souza, Vanessa Ha, Arash Mirrahimi, Sonia Blanco-Mejia, Marco Di Buono, Alexandra L Jenkins, Lawrence A Leiter, Thomas MS Wolever, Joseph Beyene, Cyril WC Kendall, David JA Jenkins, and John L Sievenpiper.  Am J Clin Nutr 2015; 102:914-921 doi:10.3945/ajcn.115.107243.

• Conclusions: SSBs were associated with a modest risk of developing hypertension in 6 cohorts. There is a need for high-quality randomized trials to assess the role of SSBs in the development of hypertension and its complications.
• Funding: “The Canadian Institutes of Health Research…through the Canada-wide Human Nutrition Trialists’ Network and by the Diet, Digestive Tract, and Disease (3D) Centre, which is funded through the Canada Foundation for Innovation.  The Ministry of Research and Innovation’s Ontario Research Fund provided the infrastructure for the conduct of this project.”  Some of the investigators also received funds from Canadian government agencies or health associations.
• Authors’ funding disclosures: RJdS has received research support from the Calorie Control Council and the Coca-Cola Company…ALJ is a part owner, vice president, and director of research of Glycemic Index Laboratories, Toronto, Canada….JB has received research support from the Calorie Control Council and The Coca-Cola Company…CWCK has received research support from the Calorie Control Council, the Coca-Cola Company (investigator initiated, unrestricted grant), Hain Celestial, Kellogg, Kraft, Loblaw Companies Ltd., Solae, and Unilever…DJAJ has received research grants from Loblaw Companies Ltd., Unilever, the Coca-Cola Company… JLS has received research support from the Calorie Control Council and the Coca-Cola Company…travel funding, speaker fees, or honoraria from the Calorie Control Council, the Canadian Sugar Institute, World Sugar Research Organization, White Wave Foods, Abbott Laboratories, Dairy Farmers of Canada, Dr. Pepper Snapple Group, The Coca-Cola Company, and the Corn Refiners Association….

Comment

This is an exception that proves the rule.  In this study, a group of investigators, some—but not all— of whom typically receive funding from food companies, participated in a study funded by Canadian government and health agencies.

One possible explanation is that when investigators typically funded by soda companies are funded independently,  they design and conduct independent research.

If nothing else, this study is evidence for the need for and value of independent funding of nutrition research.

A reminder that since mid-March I’ve been collecting studies funding by food companies.  These greatly tend to produce results favorable to the sponsor’s interests.  Today’s group makes 70.  I have an ongoing call out for sponsored studies that don’t.  So far I’ve found 5 .  If you run across either kind, please send.

Breakfasts Higher in Protein Increase Postprandial Energy Expenditure, Increase Fat Oxidation, and Reduce Hunger in Overweight Children from 8 to 12 Years of Age. Jamie I Baum, Michelle Gray, and Ashley Binns.  J Nutr 2015;145:2229–35.

• Conclusion: This study indicates that breakfast macronutrient composition affects postprandial responses in both NW [normal weight] and OW [overweight] children. A PRO [high protein breakfast] increases postprandial EE [energy expenditure] and fat oxidation, reduces hunger, and increases satiety when compared with a carbohydrate-based breakfast.
• Funding: Supported by a grant from the Egg Nutrition Center/American Egg Board, Chicago, IL.
• Added note: this one is a repeat of one posted earlier.

Dietary Whey and Casein Differentially Affect Energy Balance, Gut Hormones, Glucose Metabolism, and Taste Preference in Diet-Induced Obese Rats.  Adel Pezeshki, Andrew Fahim, and Prasanth K Chelikani. J. Nutr. 2015; 145:2236-2244 doi:10.3945/jn.115.213843

• Conclusion: Together, these data demonstrate that in obese rats, whey, casein, and their combination improve energy balance through differential effects on food intake, taste preference, energy expenditure, glucose tolerance, and gut hormone secretion.
• Funding: Supported by operating grants from the Alberta Livestock and Meat Agency, Alberta Innovates Bio-Solutions, Alberta Milk…Whey protein isolate for this study was donated by Agropur Dairy Cooperative (Canada).

Consumption of Yogurt, Low-Fat Milk, and Other Low-Fat Dairy Products Is Associated with Lower Risk of Metabolic Syndrome Incidence in an Elderly Mediterranean Population.  Nancy Babio, Nerea Becerra-Tomás, Miguel Ángel Martínez-González, Dolores Corella, Ramon Estruch, Emilio Ros, Carmen Sayón-Orea, Montserrat Fitó, Lluís Serra-Majem, Fernando Arós, Rosa M Lamuela-Raventós, José Lapetra, Enrique Gómez-Gracia, Miguel Fiol, Andrés Díaz-López, José V Sorlí, J Alfredo Martínez, Jordi Salas-Salvadó, on behalf of the PREDIMED Investigators.  J. Nutr. 2015; 145:2308-2316 doi:10.3945/jn.115.214593

• Conclusions: Higher consumption of low-fat dairy products, yogurt (total, low-fat, and whole-fat yogurt) and low-fat milk was associated with a reduced risk of MetS [metabolic syndrome] in individuals at high cardiovascular disease risk from a Mediterranean population. Conversely, higher consumption of cheese was related to a higher risk of MetS.
• Funding: This study was funded in part by the Spanish Ministry of Health…Thematic Network…the European Regional Development Fund, and the Catalan Nutrition Center of the Institute of Catalan Studies.
• Author disclosures: N Babio received consulting fees from Danone. R Estruch served on the board of, and received lecture fees from, the Research Foundation on Wine and Nutrition…E Ros served on the board of, and received travel support and grant support through his institution from the California Walnut Commission; served on the board of the Flora Foundation (Unilever)… L Serra-Majem is a member of the Scientific Advisory Board and received consulting fees and grant support from the European Hydratation Institute, received lecture fees from the International Nut Council, and received travel support from Nestle. F Arós received payment for the development of educational presentations from Menarini and Astra Zeneca. RM Lamuela-Raventós serves on the board of, and received lecture fees from, the Research Foundation on Wine and Nutrition; received lecture fees from Cerveceros de España; and received lecture fees and travel support from PepsiCo. J Salas-Salvadó served on the board of, and received grant support through his institution from the International Nut and Dried Fruit Council; received consulting fees from Danone; and received grant support through his institution from Eroski and Nestlé. N Becerra-Tomás, MÁ Martínez-González, D Corella, C Sayón-Orea, M Fitó, J Lapetra, E Gómez-Gracia, M Fiol, A Díaz-López, JV Sorlí, and JA Martínez, no conflicts of interest.
• Comment: This study was funded by independent agencies but the authors report many financial connections to food companies.

Type and amount of dietary protein in the treatment of metabolic syndrome: a randomized controlled trial.  Alison M Hill, Kristina A Harris Jackson, Michael A Roussell, Sheila G West, and Penny M Kris-Etherton.  Am J Clin Nutr 2015; 102:757-770 doi:10.3945/ajcn.114.104026

• Conclusions: Weight loss was the primary modifier of MetS [metabolic syndrome] resolution in our study population regardless of protein source or amount. Our findings demonstrate that heart-healthy weight-loss dietary patterns that emphasize either animal or plant protein improve MetS criteria similarly.
• Funding: Supported by The Beef Checkoff and the General Clinical Research Center, The Pennsylvania State University.
• Comment: The point of this study was to demonstrate that animal protein is not harmful.

Oral Vitamin D Supplements Increase Serum 25-Hydroxyvitamin D in Postmenopausal Women and Reduce Bone Calcium Flux Measured by ⁴¹Ca Skeletal Labeling.  Andreas Schild, Isabelle Herter-Aeberli, Karin Fattinger, Sarah Anderegg, Tim Schulze-König, Christof Vockenhuber, Hans-Arno Synal, Heike Bischoff-Ferrari, Peter Weber, Arnold von Eckardstein, and Michael B Zimmermann.  J. Nutr. 2015; 145:2333-2340 doi:10.3945/jn.115.215004

• Conclusion: In healthy postmenopausal women, increasing serum 25(OH)D primarily affects calcium transfer from the central compartment to a fast exchanging compartment…A serum 25(OH)D concentration of ∼40 μg/L achieves ∼90% of the expected maximal effect on this transfer rate.
• Funding: This study was supported by DSM Nutritional Products Ltd. and the ETH Zurich, Switzerland.
• Author disclosures: P Weber is employed by DSM Nutritional Products.
• Comment: Although this study addresses a basic research question, its results favor the use of vitamin D supplements and, therefore, the interests of this supplement company.

Consumption of Honey, Sucrose, and High-Fructose Corn Syrup Produces Similar Metabolic Effects in Glucose-Tolerant and -Intolerant Individuals.  Susan K Raatz, LuAnn K Johnson, and Matthew J Picklo.  J. Nutr. 2015; 145:2265-2272 doi:10.3945/jn.115.218016 

• Conclusions: Daily intake of 50 g carbohydrate from honey, sucrose, or HFCS55 for 14 d resulted in similar effects on measures of glycemia, lipid metabolism, and inflammation. All 3 increased TG [triglyceride] concentrations in both GT [glucose tolerant] and IGT [glucose intolerant] individuals and elevated glycemic and inflammatory responses in the latter.
• Funding: Supported by a grant from the National Honey Board and by the USDA Agricultural Research Service.
• Comment.  The authors hypothesized that honey would result in improved glycemia and insulin sensitivity compared with sucrose and HFCS.  But they found that their “data do not support the contention that the consumption of honey vs. HFCS or sucrose provides an added health benefit for maintenance of glucose homeostasis and other cardiometabolic outcomes because all 3 sugars evaluated exerted similar metabolic effects.”

Sugar-sweetened beverage consumption and incident hypertension: a systematic review and meta-analysis of prospective cohorts.  Viranda H Jayalath, Russell J de Souza, Vanessa Ha, Arash Mirrahimi, Sonia Blanco-Mejia, Marco Di Buono, Alexandra L Jenkins, Lawrence A Leiter, Thomas MS Wolever, Joseph Beyene, Cyril WC Kendall, David JA Jenkins, and John L Sievenpiper.  Am J Clin Nutr 2015; 102:914-921 doi:10.3945/ajcn.115.107243.

• Conclusions: SSBs were associated with a modest risk of developing hypertension in 6 cohorts. There is a need for high-quality randomized trials to assess the role of SSBs in the development of hypertension and its complications.
• Funding: “The Canadian Institutes of Health Research…through the Canada-wide Human Nutrition Trialists’ Network and by the Diet, Digestive Tract, and Disease (3D) Centre, which is funded through the Canada Foundation for Innovation.  The Ministry of Research and Innovation’s Ontario Research Fund provided the infrastructure for the conduct of this project.”  Some of the investigators also received funds from other Canadian government agencies or health associations.  This, therefore is actually an independently funded study.
• Authors’ funding disclosures: RJdS has received research support from the Calorie Control Council and the Coca-Cola Company…ALJ is a part owner, vice president, and director of research of Glycemic Index Laboratories, Toronto, Canada….JB has received research support from the Calorie Control Council and The Coca-Cola Company…CWCK has received research support from the Calorie Control Council, the Coca-Cola Company (investigator initiated, unrestricted grant), Hain Celestial, Kellogg, Kraft, Loblaw Companies Ltd., Solae, and Unilever…DJAJ has received research grants from Loblaw Companies Ltd., Unilever, the Coca-Cola Company… JLS has received research support from the Calorie Control Council and the Coca-Cola Company…travel funding, speaker fees, or honoraria from the Calorie Control Council, the Canadian Sugar Institute, World Sugar Research Organization, White Wave Foods, Abbott Laboratories, Dairy Farmers of Canada, Dr. Pepper Snapple Group, The Coca-Cola Company, and the Corn Refiners Association….
• Comment: In this study, a group of investigators, some—but not all— of whom typically receive funding from food companies, participated in a study funded by Canadian government and health agencies.  If nothing else, this study is evidence for the importance of independent funding of nutrition research.

The score, for those of you following this saga, is now 65 studies with results favoring the sponsor to 5 with unfavorable results.  But I will soon be posting another 5 of the former kind.

Sugars item #2 for this week (about half of the sugars in US diets come from sugar-sweetened beverages)

As promised in his op-ed in the Wall Street Journal in August, Muhtar Kent, the CEO of Coca-Cola, is making its funding transparent.  He said he “directed Sandy Douglas, president of Coca-Cola North America, to”

Publish on our website a list of our efforts to reduce calories and market responsibly, along with a list of health and well-being partnerships and research activities we have funded in the past five years, which we will continue to update every six months.

True to his word, here is Coca-Cola’s commitment to transparency:

• The company’s transparency website
• A list of the organizations it funds
• A list of the scientific experts and researchers it funds (but some declined to be listed)
• Answers to frequently asked questions

This makes interesting reading, to say the least.  Enjoy!

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.”

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).

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.
