Latest from Food Politics: Industry funded study of of the week: raspberries

Who knew raspberries were an industry.   As it happens, every food has its own industry, each more desperate than the next to prove it is a superfood so you will buy it and not its competing foods. Here’s how I heard about this one: Red raspberries ...

By Marion Nestle June 22 2026 Industry funded study of of the week: raspberries Who knew raspberries were an industry.  As it happens, every food has its own industry, each more desperate than the next to prove it is a superfood so you will buy it and not its competing foods. Here’s how I heard about this one: Red raspberries linked to better blood sugar control and memory in older adults:  Adding a cup of red raspberries to a carbohydrate‑rich meal may help curb post‑meal glucose and insulin spikes while supporting short-term cognitive performance in older obese or overweight adults…. Read more As always, I went right to it: The study: Xiao D, Shukitt-Hale B, Rutledge GA, Fisher DR, Edirisinghe I, Burton-Freeman B. Red raspberry improves postprandial metabolic indices and cognitive function in older adults who are overweight or have obesity. British Journal of Nutrition. Published online 2026:1-13. doi:10.1017/S0007114525105497 Method:“This randomised, single-blinded, controlled crossover study evaluated the acute metabolic and cognitive effects of RRB intake in older adults (55–70 years) with overweight/obesity. Conclusion: “These findings suggest that acute RRB supplementation attenuated postprandial metabolic stress, reduced markers of neuroinflammation and improved cognitive performance, supporting RRB’s potential role in a dietary strategy for ageing populations.” Acknowledgments: “This work was supported by the National Processed Raspberry Council and the Washington Red Raspberry Commission (WA, USA). The authors thank Van Drunen Farms (Momence, IL, USA) for providing the freeze-dried red raspberry powder used in this project…The authors declare no conflicts of interest. Comment: Et tu, raspberries?  They are coming into season on my Manhattan terrace and I do love to go out in the morning and pick them for breakfast in the week or so that they produce fruit.  I’ll take whatever short-term cognitive benefit they convey.  But c’mon.  Can one fruit, no matter how delicious, organically grown, local, and seasonal deliver on such promises?  Seems like a lot to ask.  And I continue to be amazed that the researchers see no conflict of interest in having their study funded by raspberry trade groups, when so much evidence demonstrates commercial funding to influence research outcome.  This is one of those studies where I could predict the funder from the title, and predict the outcome from knowing the funder.   The post Industry funded study of of the week: raspberries appeared first on Food Politics by Marion Nestle      Related Posts Industry funded study of the week: beef again A rare exception: an industry-funded study with negative results Industry-funded study of the week: Full-fat dairy and body weight   Now Available: What to Eat Now My new book, What to Eat Now, is officially out!
