A new research study has suggested that regular egg consumption may be associated with a reduced risk of dementia, including Alzheimer’s disease, particularly among older adults.
The findings, based on long-term observational research, indicate that individuals who consume eggs frequently may have lower chances of developing cognitive decline compared to those who avoid them entirely.
According to researchers at Loma Linda University, older adults who eat eggs five or more times per week showed up to a 27% lower risk of Alzheimer’s disease. Those consuming eggs two to four times weekly experienced around a 20% reduction in risk, while even occasional consumers showed a 17% lower risk compared to non-consumers.
The study followed approximately 40,000 participants over a 15-year period. During this time, 2,858 individuals were diagnosed with Alzheimer’s disease, which is the most common form of dementia worldwide.
Researchers observed that participants who did not consume eggs at all had the highest recorded risk of developing Alzheimer’s disease, suggesting a potential link between dietary habits and long-term brain health outcomes.
Experts highlighted that eggs contain several nutrients considered beneficial for brain function, including choline, vitamin B12, vitamin D, selenium, iodine, and omega-3 fatty acids. These nutrients are believed to support memory, cognitive performance, and overall neurological health.
However, scientists emphasized that the research is observational in nature, meaning it cannot establish a direct cause-and-effect relationship between egg consumption and reduced dementia risk. Instead, it identifies a correlation that requires further clinical investigation.
Previous studies on the role of eggs in brain health have produced mixed results, and health experts continue to recommend moderation as part of a balanced diet rather than relying on a single food for disease prevention.
Nutrition specialists also note that the overall health impact of eggs often depends on preparation methods and accompanying foods, such as excessive use of unhealthy fats or processed ingredients.
Despite ongoing debate, eggs remain widely regarded as a nutrient-rich and accessible food that can contribute positively to a balanced dietary pattern.
As research continues, scientists aim to better understand how long-term dietary habits influence brain aging and whether specific nutrients can help reduce the risk of neurodegenerative diseases.
