A new study suggests that eating eggs regularly may be linked to a lower risk of developing Alzheimer’s disease in older adults.
Researchers followed nearly 40,000 adults aged 65 and above for more than 15 years. They found that people who consumed eggs more often had a lower chance of being diagnosed with Alzheimer’s disease compared with those who rarely or never ate eggs.
The study reported that adults who ate eggs five or more times a week had a 27 per cent lower risk of Alzheimer’s disease. Even moderate intake appeared to offer benefits. Eating eggs one to three times a month was associated with a 17 per cent lower risk, while consuming eggs two to four times a week was linked to a 20 per cent lower risk.
Why eggs may support brain health
Researchers say eggs contain several nutrients that may support healthy brain ageing. One of the key nutrients is choline, which the body uses to produce acetylcholine, a chemical messenger that plays an important role in memory and learning.
Eggs also contain vitamin B12, lutein, and omega-3 fatty acids. These nutrients have been linked to cognitive function and may help support brain health as people grow older.
An important point to remember
Although the findings are promising, the study does not prove that eggs directly prevent Alzheimer’s disease.
This was an observational study, meaning it only found an association between egg consumption and lower risk. It is possible that people who eat eggs regularly may also have healthier lifestyles overall, including better diets, more physical activity, or other habits that contribute to brain health.
What this means for daily diet
The findings add to growing evidence that diet can play an important role in healthy ageing and cognitive well-being.
Including eggs as part of a balanced diet may be one simple way to support long-term brain health. However, experts say no single food can prevent Alzheimer’s disease on its own.
A healthy lifestyle remains essential. Regular exercise, good sleep, stress management, and a diet rich in fruits, vegetables, whole grains, legumes, and healthy fats all continue to play an important role in lowering the risk of cognitive decline.
