Study Links Eggs to Lower Alzheimer’s Risk
A long-term study suggests that eating eggs regularly may be associated with a lower risk of developing Alzheimer’s disease in older adults. Researchers analyzed data from nearly 40,000 participants, tracking their dietary habits and health outcomes over time. During the study period, about 2,800 participants developed Alzheimer’s disease, a progressive condition and a leading cause of death in the United States.
People who consumed eggs had a lower risk of developing Alzheimer’s compared to those who rarely or never ate them. Participants who ate eggs two to four times per week had about a 20% lower risk. Those who ate eggs five or more times weekly had about a 27% lower risk. In contrast, people who did not eat eggs had a higher risk compared to those with moderate intake.
Nutrients in Eggs May Support Brain Health
Eggs contain several nutrients linked to brain health, including choline, omega-3 fatty acids, and vitamin B12. These compounds are known to play roles in cognitive function and neural protection. However, the study does not prove that eating eggs prevents Alzheimer’s disease. The authors emphasize that the research identifies an association, and other factors could play a role.
The study focused on a health-conscious population, which may limit the extent to which the findings apply to the general public. Researchers say identifying lifestyle factors that could influence risk remains an important area of study. The authors say further research is needed to better understand how diet, including egg consumption, may affect long-term brain health.
As always, individuals should consult a healthcare professional before making significant dietary changes. This study adds to the growing body of evidence linking diet to brain health, but more work is needed to confirm causal relationships.
