New Study Finds Eggs May Help Lower Alzheimer’s Risk

Eggs may be getting a surprising brain-health boost.

A new study from Loma Linda University Health found that adults age 65 and older who ate eggs five or more times per week had up to a 27% lower risk of developing Alzheimer’s disease compared with those who never ate eggs.

That is an attention-grabbing finding, especially at a time when more than 7 million Americans are currently living with Alzheimer’s disease. For families, caregivers, and communities, any research pointing toward everyday prevention is worth paying attention to.

So why eggs?

One key reason may be choline, a nutrient found in egg yolks. Choline helps the body produce acetylcholine, a brain chemical involved in memory, learning, and communication between nerve cells. Eggs also contain other nutrients that support healthy aging, including protein, vitamin B12, lutein, and zeaxanthin.

That does not mean eggs are a magic shield against Alzheimer’s. The study shows an association, not a guarantee. People who eat eggs regularly may also have other habits that support brain health, such as eating a balanced diet, staying active, sleeping well, and managing chronic health conditions.

Still, the findings are encouraging because eggs are affordable, familiar, and easy to work into everyday meals.

A hard-boiled egg with breakfast. A veggie omelet. Eggs on whole-grain toast. A simple frittata for dinner. These small choices can fit into a broader brain-friendly lifestyle without feeling complicated or expensive.

Experts continue to point to the bigger picture when it comes to reducing dementia risk: regular movement, quality sleep, managing blood pressure and diabetes, staying socially connected, not smoking, and eating a nutrient-rich diet.

But studies like this are a helpful reminder that brain health is not only shaped by big medical breakthroughs. It can also be influenced by the simple habits we build into daily life.

Eggs will not prevent Alzheimer’s on their own. But they may be one smart, accessible piece of a larger brain-health puzzle.

And that makes breakfast feel a little more powerful.
