Eggs Reduce Alzheimer’s Risk By 47% (Here’s What They Don’t Tell You)
In a Nutshell
Eggs supply critical brain nutrients—choline, lutein, high-quality protein, and cholesterol—that support acetylcholine production and myelin protection, which are often deficient in Alzheimer's. The 47% risk reduction claim stems from comparing healthy egg eaters to an unhealthy group, not a guaranteed personal benefit. Pasture-raised eggs deliver far more lutein and a better omega-3 balance than conventional eggs, while ketones from low-carb eating provide an insulin-independent fuel source when glucose uptake fails in the brain.

There's a study making headlines that eggs reduce Alzheimer's risk by 47%. This does not mean that consuming eggs will lower your personal risk for Alzheimer's by 47%. The 47% decrease comes from comparing a group that consumes eggs in a relatively healthy manner to a very unhealthy group. The percentage does not guarantee the same result when an individual begins consuming eggs.
The Egg Nutrition Center is funded through the American Egg Board, a governmental program created in 1976. The single largest egg producer in the US sits on that board.
An egg is very different from meat. An egg has evolved to build an entire organism. Researchers have cataloged over 854 different proteins in a single egg.
One protein is lysozyme, a natural antibacterial that has been found in trials to lower blood pressure by nearly eight points. The IGY antibody has been shown in randomized controlled trials to reduce H. pylori by 39%. Cystatin is a protein studied in Alzheimer's animal models that improves memory. Another protein was studied in perimenopausal women and shown to help maintain bone density.
Choline is a major benefit of eggs for brain health. The brain communicates using acetylcholine. In Alzheimer's disease, the neurons that produce acetylcholine are the first ones to die. Consuming two eggs provides 300 mg of choline, more than almost any other food except liver. People who do not eat eggs or liver are likely deficient in choline. The most widely prescribed Alzheimer's drugs work by preventing the breakdown of acetylcholine rather than increasing it.
