A simple eating habit could have a significant impact in preventing Alzheimer's: eating one egg a week. This is what emerges from research conducted by Rush University in Chicago, which found a link between regular egg consumption and a reduced risk of developing dementia and neurodegenerative diseases.
Eggs and Alzheimer's: Choline's Role in Brain Health
Egg yolk is rich in choline, a nutrient essential for the functioning of the nervous system and the production of acetylcholine, the key neurotransmitter for memory and cognitive function. According to the researchers, supplementing choline into the diet through the consumption of eggs may represent a simple and effective dietary strategy for preserving memory as we age.
The study: eating eggs reduces the risk of Alzheimer's by 47%
The research, published in the Journal of Nutrition, followed over 1,000 elderly people without symptoms of dementia for seven years. The results show that those who consumed at least one egg per week had a 47% lower risk of developing Alzheimer's disease than those who ate less than one per month.
Fewer beta-amyloid plaques and pathological signs
Post-mortem analysis of the participants' brains revealed that those who regularly consumed eggs showed less presence of beta-amyloid plaques and neurofibrillary tangles, two hallmarks of Alzheimer's disease. According to the researchers, about 40% of the observed benefit was attributable to the high choline intake.
Choline and omega-3: a neuroprotective combination
In addition to choline, eggs also contain omega-3 fatty acids, which are known for their protective effects on the brain. This combination of nutrients makes eggs a complete food for supporting cognitive function.
Expert conclusions
"Our findings confirm that food choices can impact cognitive health and Alzheimer's prevention," said Dr. Taylor Wallace, lead author of the study. "Even a simple habit like eating eggs at least once a week can offer significant protection against cognitive decline."
