Adventist Health Study‑2, a large U.S. cohort of Seventh‑Day Adventists, linked its diet data to Medicare records to track Alzheimer’s diagnoses. Researchers examined egg consumption across 39,498 participants over an average 15.3‑year follow‑up. Findings show a clear inverse trend: higher egg intake aligns with lower Alzheimer’s risk. This pattern held after adjusting for demographics, lifestyle, and comorbidities, underscoring diet’s role today.

Participants eating eggs once a week had a hazard ratio of 0.83, while those consuming five or more times weekly saw a ratio of 0.73. A restricted cubic spline revealed a curvilinear drop: zero egg intake carried an adjusted HR of 1.22 versus 10 g/d. These numbers suggest a dose‑response link between eggs and neuroprotection for future research strategies that target.

These results reinforce the value of moderate egg consumption as part of a balanced diet for cognitive health. Nutritionists can cite the study to advocate eggs as a nutrient‑dense option, while public health guidelines may consider incorporating egg intake thresholds. Ultimately, the research offers a concrete dietary lever that could help curb Alzheimer’s incidence in health‑conscious populations for lifetime well‑being.
