Eating 5+ Eggs Weekly Linked to 27% Lower Alzheimer's Risk

Scientists just discovered another reason to feel good about eggs at breakfast.

A new study published in The Journal of Nutrition found that people who ate eggs more than five times a week had up to a 27% lower risk of developing Alzheimer's disease compared to those who rarely or never ate them. Even eating just one to three eggs a month showed benefits, with a 17% lower risk.

The research followed nearly 40,000 people in the U.S. and Canada for almost 15 years. During that time, 2,858 participants were diagnosed with Alzheimer's, giving researchers a large dataset to identify meaningful patterns.

This isn't the first time eggs have shown promise for brain health. A 2024 study found that adults who ate more than one egg per week had a 47% lower risk of developing Alzheimer's disease, adding weight to these latest findings.

So what makes eggs potentially protective? They're packed with nutrients that support brain function, including choline, omega-3 fatty acids, lutein, zeaxanthin, and vitamin B12. These nutrients work together to support memory, protect against inflammation, and keep neurotransmitters functioning properly.

Dr. Jisoo Oh, the study's lead author and epidemiology professor at Loma Linda University, emphasizes that eggs should be part of a bigger picture. "Moderate egg consumption as part of a healthy diet may support brain health," she says, noting that established prevention strategies like regular exercise and cardiovascular care remain essential.

The good news gets better when you consider accessibility. At roughly $2 per dozen in many areas, eggs are one of the most affordable sources of high-quality protein and brain-supporting nutrients available at any grocery store.

The Bright Side

While we don't yet have a cure for Alzheimer's, research like this shows we're not powerless against it. Small, consistent dietary choices appear to make a real difference in reducing risk.

Experts recommend pairing egg consumption with proven brain-healthy eating patterns like the Mediterranean diet or MIND diet, both of which already include eggs as part of their framework. Combined with regular physical activity and good cardiovascular health, these simple steps give people concrete ways to invest in their future brain health today.

Every new piece of the Alzheimer's prevention puzzle brings us closer to a future where fewer families face this devastating disease.
