Science Sphere repost 🍳 Could eating just one egg a week protect your brain? A new study of over 1,000 older adults suggests it might. Researchers found that people who ate at least one egg per week had a 47% lower risk of developing Alzheimer’s disease compared to those who ate eggs less than once a month. And brain autopsies revealed something remarkable: regular egg-eaters had less buildup of the toxic proteins linked to Alzheimer’s.What’s behind this? Eggs are rich in choline and omega-3 fatty acids, two nutrients essential for brain health. Choline supports memory and learning by fueling the neurotransmitter acetylcholine and regulating gene expression tied to cognition. Omega-3s have long been known for their anti-inflammatory and neuroprotective properties. Together, they may act synergistically to protect the aging brain.The findings, published in The Journal of Nutrition, offer a promising, low-cost dietary strategy for supporting cognitive health. While more studies are needed to confirm the effect, experts agree: eggs can be a smart addition to a balanced diet—especially in later life.No single food prevents dementia, but one egg a week might be a brain-friendly start.Follow Science Sphere for regular scientific updates.RESEARCH PAPER 📄Yongyi Pan et al, "Association of Egg Intake With Alzheimer’s Dementia Risk in Older Adults: The Rush Memory and Aging Project.", The Journal of Nutrition (2025)
