A new study shows that eating eggs may be good for your brain. The research looked at over 1,000 adults in the United States and found that people who ate more than one egg a week had a lower chance of getting Alzheimer’s disease.

Alzheimer’s is a condition that causes short-term memory loss and changes how the brain works. It usually affects older adults and can make daily life harder over time for the individual and their family. Scientists are always looking for ways to help prevent this disease—and diet may be one of them.

In this study, people were followed for almost seven years. During that time, 280 people—about 27%—were diagnosed with Alzheimer’s dementia. But the people who ate eggs regularly had a 47% lower risk of getting the disease compared to those who didn’t eat eggs as often.

One of the reasons eggs might help is because of a nutrient called choline. Choline is mostly found in egg yolks and helps with memory and brain function. The study found that 39% of the protective effect of eggs came from choline. This means that choline could play a big role in helping the brain stay healthy.

So, what does this mean for your diet? It’s simple: eating a few eggs each week, especially with the yolk, may be a small step toward protecting your brain. Eggs are also affordable, easy to cook, and packed with other good nutrients like protein and vitamins.

As family doctors, we know that no single food can prevent a disease. But adding healthy foods like eggs to a balanced diet can make a big difference over time. If you’re already eating eggs a few times a week, you’re likely doing your brain a favor!

Of course, everyone’s health is different. If you have high cholesterol or other health concerns, talk to your doctor before making big changes to your diet.

In summary:

• Eating more than one egg per week may lower your risk of Alzheimer’s disease.
• Eggs are rich in choline, which helps support memory and brain health.
• This benefit is linked mostly to the egg yolk, so don’t skip it.
• A healthy diet, including eggs in moderation, can be part of a brain-smart lifestyle.
