Study finds that eating eggs is associated with a lower risk of developing Alzheimer’s disease

Eggs for brain health are getting fresh attention as a new study finds a strong link between egg consumption and a lower risk of Alzheimer’s disease.

Though often debated in the past, eggs are once again seen as a valuable part of a balanced diet—especially for older adults concerned about brain health.

The research, published in The Journal of Nutrition, points to nutrients in eggs that may play a key role in protecting memory as we age.

A fresh look at eggs for brain health

Eggs have been part of human diets for thousands of years. They’re affordable, easy to prepare, and full of nutrients.

However, eggs have faced criticism over the past few decades due to their cholesterol content.

Today, that view is changing. Nutrition science shows that dietary cholesterol doesn’t raise blood cholesterol levels as much as once believed.

As a result, many experts are now looking at eggs through a different lens—especially when it comes to supporting cognitive health and lowering Alzheimer’s risk.

Study finds link between eggs and Alzheimer’s risk

In this recent study, researchers followed 1,024 older adults in Illinois for nearly seven years.

All participants were part of retirement communities or residential facilities, with an average age of 81. They completed annual checkups and food questionnaires during the study period.

The results were promising. People who ate at least one egg per week had a 47% lower risk of developing Alzheimer’s compared to those who ate fewer than one egg per month.

Even more, researchers studied the brain tissue of 578 participants who passed away during the study.

They found that regular egg eaters had less buildup of harmful proteins linked to Alzheimer’s.

Nutrients in eggs may be key

So why might eggs help protect the brain? Scientists say the answer may lie in two powerful nutrients: choline and omega‑3 fatty acids.

Choline is essential for brain health. It helps with memory, learning, and overall brain function. Omega‑3s are known for their anti-inflammatory and protective effects, especially as the brain ages.

“About 39–40% of the protective effect was explained by higher dietary choline intake,” Christopher U. Missling, PhD, president and CEO of Anavex Life Sciences, who was not involved in the study, told MNT.

“Egg yolks also contain omega-3 fatty acids, which have known neuroprotective properties. The combination of choline and omega-3s may be particularly beneficial for brain health,” he added.

This natural pairing found in eggs could explain why egg consumption is tied to reduced Alzheimer’s risk.

Eggs support older adults’ nutrition

For seniors, eggs offer more than just nutrients. They’re soft, easy to chew, quick to cook, and comforting—making them a go-to food in many homes.

As registered dietitian Maddie Gallivan noted, “Eggs are often a go-to food for older adults, as they’re soft in texture, which can be helpful for those with dentures, quick to prepare, and packed with key nutrients. So it’s great to see a study focussing on how they may support cognitive health in later life.”

This added benefit makes eggs a practical, everyday option for those caring for their minds and bodies.

Future of research on eggs and brain health

Although the study showed strong results, the authors stress that more research is needed. The data came from a specific group of older adults in the U.S., and their findings must be tested in other populations and through clinical trials.

Still, the researchers remain hopeful about what this study could mean for the future.

They explained that if the results are repeated in other long-term studies and confirmed through clinical trials, eggs could have a meaningful impact on public health—possibly helping to lower the number of people at risk for Alzheimer’s disease.

If future studies confirm these results, eggs could become an essential tool in preventing cognitive decline—an affordable, accessible food with brain-boosting potential.

Balanced eating still matters most

While focusing on eggs for brain health is exciting, experts agree on one crucial point: it’s not just about one food. A healthy brain depends on the overall pattern of what we eat.

Gallivan reminds us, “It’s important to remember that no single food acts in isolation, and our overall dietary pattern really counts. A varied, nutrient-dense diet rich in whole foods supports brain health and reduces dementia risk.”

In other words, eggs can be helpful—but they work best alongside fruits, vegetables, whole grains, nuts, and other nutrient-packed foods.

Why eggs for brain health may be a wise everyday choice

This new study adds to growing interest in how everyday foods like eggs can impact Alzheimer’s risk and brain health.

Thanks to the natural pairing of choline and omega‑3, eggs may offer a simple way to support the mind—especially in later years.

Whether scrambled, boiled, or poached, including eggs in a balanced diet could be one small step toward better memory, clearer thinking, and a healthier brain for life.
