I’m keynoting the workship on Food, Ethics, Politics at 4:00 with a reception to follow. My talk, “”Food, Ethics, Politics: The View from 2022,” will be in the Andlinger Center for Energy and the Environment, Maeder Hall, Room 002. This event is part of the University Center for Human Values (UCHV) Conferences, Workshops & Special Events. To register to attend, click here.
Five more sponsored studies with expected results. The score: 80:6
In case you haven’t been following this saga, I’ve been collecting studies funded by food companies since last March and posting them according to whether the results do or do not favor the sponsor’s interests. So far, I’ve reported 80 that do, versus 6 that don’t (although I have a couple more saved up for posting soon).
The point of this exercise is to demonstrate that sponsored studies are far more likely to favor the interests of the sponsor than are studies funded by government agencies or foundations, and to argue for more independent funding of food and nutrition research (see my recent Viewpoint on this topic in JAMA Internal Medicine).
Here are five more examples.
Is consuming yoghurt associated with weight management outcomes? Results from a systematic review. J Eales, I Lenoir-Wijnkoop, S King, H Wood, F J Kok, R Shamir, A Prentice, M Edwards, J Glanville, R L Atkinson. Int’l J Obesity 2015 ahead of print.
- Conclusions: Yoghurt consumption is associated with lower BMI, lower body weight/weight gain, smaller waist circumference and lower body fat in epidemiological studies. RCTs [randomized controlled trials] suggest weight reduction effects, but do not permit determination of a cause/effect relationship. Well-controlled, adequately powered trials in research and community settings appear likely to identify a modest but beneficial effect of yoghurt consumption for prevention of weight gain and management of obesity. The ready availability of yoghurt (a nutrient dense food) and its ease of introduction to most diets, suggests that educating the public to eat yoghurt as part of a balanced and healthy diet may potentially contribute to improved public health.

Red Meat and Colorectal Cancer: A Quantitative Update on the State of the Epidemiologic Science. Dominik D. Alexander PhD, MSPHab*, Douglas L. Weed MD, PhDc, Paula E. Miller MPHb & Muhima A. Mohamed M PHd. J Am College Nutrition 2015;34: 521-43. DOI:10.1080/07315724.2014.992553
- Conclusion: The state of the epidemiologic science on red meat consumption and CRC [colorectal cancer] is best described in terms of weak associations, heterogeneity, an inability to disentangle effects from other dietary and lifestyle factors, lack of a clear dose-response effect, and weakening evidence over time.
- Funding: This manuscript was partially funded by Meat & Livestock Australia (MLA). MLA did not contribute to the writing, analysis, or interpretation of study findings.
- Comment: The conclusion of this industry-funded study contradicts the findings of the WHO International Agency for Research on Cancer, which finds processed meats to be carcinogenic, and red meat to be a probable carcinogen.
The challenges of nutrition policymaking. Joanne Slavin. Nutrition Journal (2015) 14:15 DOI 10.1186/s12937-015-0001-8.
- Thrust of paper: As every DGAC [Dietary Guidelines Advisory Committee] wants to be bold and set new direction, nutrition science would support that first we must do no harm with our dietary guidance. Moderation and variety must be kept front and center…A suggestion that all Americans should reduce sodium intakes is not sound and is potentially dangerous. Targeting certain foods and beverages, including chocolate milk, processed meats, added sugars, and even the noble potato as villains in the nutrition wars is not a science-based strategy and may need to be countered on the political front if appointed scientific review committees continue to take this approach.

Does low-energy sweetener consumption affect energy intake and body weight? A systematic review, including meta-analyses, of the evidence from human and animal studies PJ Rogers, PS Hogenkam , C de Graaf, S Higgs, A Lluch, AR Ness, C Penfold, R Perry, P Putz, MR Yeomansand DJ Mela.International Journal of Obesity (2015), 1–14 10 November 2015; doi:10.1038/ijo.2015.177
- Conclusions: Overall, the balance of evidence indicates that use of LES [low-energy sweeteners] in place of sugar, in children and adults, leads to reduced EI [energy intake] and BW [body weight], and possibly also when compared with water.
- Conflict of interest: Peter J Rogers has received grants from Sugar Nutrition, UK in support of research on the effects of sugar on human appetite. Cees de Graaf has received grants from the Dutch Sugar Bureau in support of a study on brain responses to sugars and low energy sweeteners. Suzanne Higgs has received a grant from Canderel in support of research on the effects of low-energy sweeteners on human appetite. Anne Lluch and David J Mela are employees and shareholders of companies that manufacture products containing sugars and low-energy sweeteners. Peter Putz is an employee of ILSI Europe.
Walnut ingestion in adults at risk for diabetes: effects on body composition, diet quality, and cardiac risk measures Valentine Yanchou Njike, Rockiy Ayettey, Paul Petraro, Judith A Treu, David L Katz. . BMJ Open Diabetes Research and Care 2015;3:e000115. doi:10.1136/bmjdrc-2015- 000115.
- Conclusions: The inclusion of walnuts in an ad libitum diet for 6 months, with or without dietary counseling to adjust calorie intake, significantly improved diet quality, endothelial function, total and LDL cholesterol, but had no effects on anthropometric measures, blood glucose level, and blood pressure.
- Funding: Funding for this study has been provided by the California Walnut Commission.
