Discovery of the day
Using a target trial emulation design with 21 years of follow-up from the Framingham Heart Study, researchers found no clear long-term protective effect of sustained fish intake on Alzheimer’s disease risk. The 21-year risk ranged from 10.33% with no fish intake to 9.98% with ≥3 servings per week, with risk ratios and risk differences near zero. For you, as a nurse and psychologist focused on chronic disease prevention and health behavior, this finding underscores the need to re-evaluate dietary recommendations for cognitive health and to communicate realistic expectations to patients about the modest impact of isolated nutritional changes.
