Post-Meal Sugar Surges Linked to Higher Alzheimer's Risk, Study Suggests
UK researchers using Mendelian randomization found that higher post-meal glucose levels within two hours after eating are associated with a 69% higher risk of Alzheimer's disease, while standard glucose/insulin measures and brain MRI changes showed no clear link. The finding requires replication in more diverse populations, but could influence future dementia prevention approaches for people with diabetes.
