Study finds inverse link between egg consumption and Alzheimer's disease
Key points
- Study involved 39,498 participants over 15 years
- Higher egg consumption linked to lower Alzheimer's risk
- Consumption categories ranged from never to ≥5 times per week
Study Overview
The research examined the relationship between egg consumption and Alzheimer's disease within a large cohort from the Adventist Health Study-2. Following participants over an average of 15.3 years, the study linked dietary habits to Medicare records to identify diagnoses of Alzheimer's disease.
Methodology
Participants completed validated food frequency questionnaires assessing dietary and lifestyle factors. Egg consumption was categorized from never/rarely to five or more times per week. Cox proportional hazards models analyzed the hazard ratios for developing Alzheimer's based on egg intake.
Key Findings
The results indicated an inverse association between egg consumption and Alzheimer's risk. Hazard ratios revealed that individuals consuming eggs 1-3 times per month had a risk reduction of 17%, while those consuming eggs 2-4 times per week saw a 20% reduction, and those consuming eggs five or more times per week had a 27% lower risk compared to non-consumers.
According to the spline model analysis, zero egg intake corresponded to a higher risk of Alzheimer's (HR: 1.22), emphasizing the potential benefits of moderate consumption.
Implications
These findings highlight that incorporating eggs, which are nutrient-dense, into a balanced diet may offer neuroprotective benefits against Alzheimer’s disease. The results can inform dietary guidelines, particularly regarding modifiable risk factors for brain health.
