Researchers have spent years investigating how diet affects the brain.
Eggs contain nutrients such as vitamin B12, omega-3 fatty acids, and choline, all of which are important for brain function.
A new study from Loma Linda University Health, published in The Journal of Nutrition and reported by Medical News Today, highlights that eggs should be included as part of a healthy and varied diet.
Researchers urge caution
The study is based on data from more than 39,000 Americans.

Many of the participants already followed healthy lifestyles, including lower rates of smoking and alcohol consumption, as well as a more plant-based diet.
Because of this, experts say caution is needed before concluding that eggs alone protect against dementia.
The study can only show an association and cannot prove causation.
Dietitian Michelle Routhenstein also points out that foods such as beans, soy, and green vegetables contain many of the same nutrients.

Eat eggs at least five times a week
The researchers found that people who ate eggs at least five times a week had up to a 27 percent lower risk of receiving an Alzheimer’s diagnosis compared to people who did not eat eggs.
Previous research has shown similar results. A 2024 study, also published in The Journal of Nutrition, found that people who ate one egg per week had a lower risk of developing the disease.
However, the researchers emphasize that more studies are still needed before it can be determined whether eggs can directly protect the brain.
