Eggs May Shield Older Brains From Alzheimer's, Study Finds

A long-term study of about 40,000 adults aged 65+ found that regular egg consumption (at least five eggs per week, including daily) is associated with up to a 27% lower risk of developing Alzheimer's disease, with even smaller amounts offering brain benefits. Eggs provide choline, lutein/zeaxanthin, and omega-3s that may support brain health; researchers caution that eggs should be part of an overall healthy diet. The findings come from the Adventist Health Study-2 cohort linked with Medicare data and were published in the Journal of Nutrition.
