New data from the Adventist Health Study-2 quantifies a striking relationship between egg consumption and cognitive protection: one large egg supplies 33% of daily choline intake, and consuming eggs five or more times weekly correlates with a 27% lower Alzheimer’s incidence over 15 years of follow-up.
The study enrolled 39,498 adults aged 65 and older, with Medicare diagnoses confirming 2,858 Alzheimer’s cases during the observation period. The dose-response relationship was consistent across consumption categories: monthly egg consumption showed a 17% risk reduction, while twice-weekly consumption demonstrated a 20% reduction.
Choline’s role as the biochemical precursor for acetylcholine—the neurotransmitter deficient in Alzheimer’s disease—provides a mechanistic explanation for these epidemiological findings. This evidence-based association suggests egg consumption may represent a modifiable dietary factor in cognitive aging. Read the full article on GMJ Newsroom.
