A study shows that being an “egg head” may actually be a smart way to go: Eggs are good for brain health.
Research from Loma Linda University Health suggests that eggs — be they in the form of scrambled, salad or deviled — may be linked to long-term brain health, particularly when it comes to Alzheimer’s disease risk in older adults.
A Possible Link Between Egg Consumption and Lower Alzheimer’s Risk
The study found an association between regular egg intake and a reduced risk of Alzheimer’s disease in adults aged 65 and older.
People who ate at least five eggs per week were reported to have up to a 27% lower risk of being diagnosed with Alzheimer’s compared to those who never ate eggs.
Even lower levels of consumption showed differences. Eating eggs just a few times per month was linked to about a 17% reduction in risk, while two to four servings per week were associated with roughly a 20% lower risk.
Eggs are especially rich in choline, a nutrient the body uses to produce compounds like acetylcholine, which is important for memory and signaling between brain cells.
Eggs also contain antioxidants such as lutein and zeaxanthin, which can accumulate in brain tissue and have been linked in other research to cognitive performance and reduced oxidative stress.
On top of that, eggs provide omega-3 fatty acids and phospholipids found in the yolk, which are involved in how brain cell receptors function.
How the Study Was Conducted
The research, published in the Journal of Nutrition, drew from the Adventist Health Study-2 cohort and included around 40,000 participants.
Egg intake was measured in detail, including both direct consumption (like boiled, scrambled or fried) and indirect sources, such as eggs used in baked goods and processed foods.
Participants were then tracked for an average of over 15 years, with Alzheimer’s diagnoses identified using Medicare health records and physician reporting data.
This long follow-up period allowed researchers to look at dietary patterns and later-life health outcomes in a large population group.
Despite the findings, researchers emphasize that eggs are not being presented as a standalone solution for preventing Alzheimer’s disease.
Instead, they are seen as one part of a broader dietary pattern that can support healthy aging.
Seventh-day Adventists — who were part of this study — tend to have generally healthier diets overall, which makes it important to interpret the results in context.
The main takeaway of the research is that overall eating patterns are more important than any single food, even one that shows promising associations like eggs.
