Most people know eggs are a good source of protein. What they might not know is that eating them regularly may be one of the simplest things you can do to protect your brain as you age.
A 2024 study from Rush University Medical Center and Tufts University followed over 1,000 adults for nearly seven years. People who ate more than one egg per week had about a 47% lower risk of developing Alzheimer’s dementia compared to those who rarely ate them. The same association showed up in brain autopsy data, where higher egg intake was linked to lower levels of Alzheimer’s disease pathology in the brain itself.
Researchers believe one key reason is choline, a nutrient found in egg yolks that supports brain function and the production of acetylcholine, a neurotransmitter involved in memory. Eggs also provide omega-3 fatty acids and lutein, both linked to cognitive health.
It was an observational study, so it shows association rather than direct cause. But it adds to a growing body of evidence that what you eat influences your long-term brain health. And eggs are one of the most accessible, affordable places to start.
Here are three easy ways to get more of them on your plate…
1. Spinach Egg and Cheese Breakfast Pita
A quick, satisfying breakfast with scrambled eggs and spinach tucked into a warm pita.
Spinach is one of the most nutrient-dense leafy greens there is, packed with folate, iron, calcium, and vitamins A, C, and K. What makes this recipe particularly smart is that the eggs actually help your body absorb spinach’s nutrients more effectively. Two brain-healthy superfoods working together in one easy meal.

2. Baked Eggs in Avocado
A simple, nourishing dish with eggs baked directly into ripe avocado halves.
Avocados are rich in healthy monounsaturated fats and folate, both of which support blood flow to the brain. Research has linked folate to a reduced risk of the brain tangles associated with Alzheimer’s disease. Paired with the choline in eggs, this is one of the most brain-friendly combinations you can put on the breakfast table.
