Eating Eggs at Least 5x a Week Could Cut Alzheimer's Risk by 27 Percent, Study Says
If eggs are a regular part of your weekly diet, don't feel like you need to alter your favorite breakfast plate just yet. Beyond being a tasty and high-protein option, eggs may offer health benefits that extend further than most people realize. In fact, new research suggests that regular egg consumption could be associated with a lower risk of developing Alzheimer's disease.
The research followed nearly 40,000 adults over an average of 15 years, tracking dietary habits and health outcomes through food questionnaires and Medicare records. Published in the Journal of Nutrition, the study analyzed data from the Adventist Health Study-2, which tracked a large cohort of Seventh-day Adventists in the United States. Over the follow-up period, 2,858 of the 39,498 participants were diagnosed with Alzheimer's disease.
Researchers found that people who ate eggs more frequently tended to have a lower risk of developing the condition. Compared with those who rarely or never consumed eggs, individuals who ate them one to three times a month had a 17 percent lower risk, while those eating them once per week showed a similar reduction.
Higher egg consumption was linked with even greater differences. People consuming eggs two to four times a week displayed a 20 percent lower risk, and those eating them at least five times a week showed as much as a 27 percent lower risk of Alzheimer's.

Researchers point to eggs' nutrition profile as a possible explanation. Eggs contain compounds like choline, B vitamins, and omega-3s, which may help support cognitive health over time.
Eggs alone may not necessarily be a protective treatment, but they prove to be a simple food that fits into a diet that supports long-term brain health. And with over 7 million Americans currently living with Alzheimer's disease, a number projected to reach 13 million by 2050, it's worth paying attention to any potential links between daily diet choices and brain health.
"Research supports eggs as part of a healthy diet," said Jisoo Oh, DrPH, MPH, lead author of the study, per a news release. "Seventh-day Adventists do eat a healthier diet than the general public, and we want people to focus on overall health along with this knowledge about the benefit of eggs."
