Study Links Egg Consumption to Lower Alzheimer’s Risk
A recent study has found a connection between eating eggs and a reduced risk of Alzheimer’s disease. Conducted by researchers at Loma Linda University in California, the findings were published in the Journal of Nutrition.
The study investigated how dietary habits could influence the chances of developing Alzheimer’s. Researchers noted that eggs are packed with important nutrients beneficial for brain health.
To conduct the study, nearly 40,000 adults aged 65 and older were analyzed, using data connected to Medicare records. Over a span of 15 years, 2,858 participants were diagnosed with Alzheimer’s. Their eating habits and lifestyles were evaluated through questionnaires.
The researchers categorized egg consumption as either “visible”—like boiled or scrambled eggs—and “hidden,” which refers to eggs used in processed foods or baked goods. Those who ate eggs five or more times a week had a 27% lower risk of developing Alzheimer’s, while those who had them just once to three times a month had a 17% lower risk. In contrast, individuals who did not consume eggs had a higher risk compared to those who ate around 10 grams a day.
The findings of this study indicate that moderate egg consumption may play a role in lowering Alzheimer’s risk. “These results suggest that the nutrients in eggs could help protect the brain when part of a healthy diet,” the researchers noted.
Dr. Joel Salinas, a neurologist at NYU Langone, described the study as “well-designed” and noted that the connection aligns with earlier research. He highlighted that eggs are rich in choline, DHA, and B12, nutrients essential for an aging brain. However, he mentioned that since the study is observational, it cannot definitively prove causation—just that there is a potential link.
Nutrition expert Lauri Wright emphasized a cautious approach in interpreting the study’s findings. She pointed out that people who regularly consume eggs often have healthier lifestyles, which may influence the outcomes. Nonetheless, she believes there are valid reasons to consider eggs part of a brain-healthy diet due to their high choline content and other nutrients linked to healthy aging.
Wright remarked that while eggs can certainly fit into a balanced diet, how they are prepared matters. Pairing eggs with vegetables, whole grains, or other wholesome foods is much healthier than serving them with processed meats or high-sodium dishes.
Ultimately, health experts agree that maintaining a well-rounded eating pattern is key to overall wellness. What’s good for the heart often benefits the brain as well, making it essential to focus on a diverse and balanced diet.
