Eggs for Brain Health: New 2026 Study Shows How They Protect Against Alzheimer’s and Boost Cognitive Performance

A major 2026 Loma Linda University study of nearly 40,000 older adults found that eating eggs is linked to a significantly lower risk of Alzheimer’s disease in a clear dose-response pattern—up to 27% reduction for those eating them 5+ times per week. Eggs deliver powerhouse nutrients like choline for memory neurotransmitters, lutein and zeaxanthin for brain antioxidant protection, and bioavailable DHA for neuron health. While observational and not definitive proof of causation, this research challenges old cholesterol fears and offers practical, tasty advice for supporting long-term cognitive health.
