Published in Nature Medicine on March 24, 2025, this research by Anne-Julie Tessier and her team examines the long-term effects of dietary habits on healthy aging.For 30 years, over 100,000 participants—nurses, doctors, and other health professionals—recorded their diets. The results? Some dietary patterns dramatically improved the odds of reaching 70, or even 75, in peak cognitive, physical, and mental health. Others, particularly those heavy in ultraprocessed foods, were linked to poorer aging outcomes.So, is there a best diet for longevity? Can what’s on your plate today determine your quality of life decades from now?Stay tuned—because the answers might change the way you think about food forever.ReferenceTessier, AJ., Wang, F., Korat, A.A. et al.
