There’s no cure for Alzheimer’s. None.
Science just chips away. Slowly. Looking for things that lower the risk. The latest guess? Eggs.
New data from The Journal of Nutrition suggests regular egg-eaters face a smaller threat from the disease. Big deal. Eggs are cheap. They’re in every grocery store. You can get them for next to nothing.
Does this mean eating an omelet will magically erase your chance of dementia? No. Not really. It adds context to diet research though. Also, keep an eye on who paid for this. The American Egg Board provided a grant. They didn’t touch the study design or the analysis. They just wrote the check.
“Moderate egg consumption as part of a healthy diet… may support brain health.” — Jisoo Oh
Who is talking?
Jisoo Oh is the lead author. She’s at Loma Linda University. Clifford Segil is a neurologist in Santa Monica. Davide Cappon runs Neuropsychology at Tufts. They’re looking at the numbers.
The data doesn’t lie. Mostly.
They watched nearly 40,00 people. Part of the Adventist Health Study-2. Long term. USA and Canada. Diet. Lifestyle. Disease.
Over 15 years.
2,858 people got Alzheimer’s. The researchers split them up by egg habits.
Eats eggs one to three times a month? Your risk drops by 17 percent compared to non-eaters.
Eats eggs two to four times a week? The drop is bigger. 20 percent.
Eats eggs more than five times a weekly cycle? The risk plummets. Up to 27 percent lower.
The pattern holds. More eggs, less disease. At least in this group.
Why eggs?
Correlation is not causation. That’s the disclaimer. Oh is clear about this. We found a link. We didn’t prove eggs save brains directly. But it fits with older ideas.
Another 2024 study in the same journal showed similar results. Over 1,00 older adults. Those eating over one egg a week had 47 percent less risk. Two authors of that piece got past money from the Egg Nutrition Center again. The funding sources stayed out of the analysis. NIH was there too. They didn’t interfere.
So what’s inside the egg?
Nutrients.
Choline. Omega-3s. Lutein. Zeaxanthin. Vitamin B12.
“These nutrients support memory… and protection against oxidative stress.” — Oh
Segil adds protein. It’s an excellent source. Prior hints suggest protein shields the brain. It’s still being studied though.
Choline specifically? It helps acetylcholine. That neurotransmitter matters for Alzheimer’s drugs. Some meds try to boost it. Eggs naturally support it.
Cappon at Tufts puts it bluntly. Small, consistent diet changes shift the odds.
How many?
No prescription exists. You can’t just buy a fix.
But the tiers are there. One to three a month helps. Two to four a week helps more. Five-plus? Best stats in the cohort.
It’s a sliding scale of protection.
Don’t just eat eggs
If you want brain health, look wider. Cappon points to the Mediterranean diet. The MIND diet. Both include eggs. Obviously.
But don’t treat the egg as the primary weapon.
Oh warns against it. It’s part of a strategy. Not the whole strategy.
Exercise.
Cardiovascular health.
Sleep.
General diet patterns.
Eggs fit in there. They might help. But you can’t eat your way to immortality on protein and cholesterol alone.
The study is observational. It watches. It doesn’t pull the trigger.
What does that mean for your breakfast tomorrow?
Who knows. But the data looks nice on paper.
