Blood Sugar Spikes May Increase Alzheimer's Risk

A new study from the University of Liverpool suggests that sudden spikes in blood sugar after meals may increase the risk of developing Alzheimer's disease. The research, published in the journal «Diabetes, Obesity and Metabolism», analyzed genetic data from over 350,000 people and found that individuals with higher post-meal blood sugar levels had a 69% increased risk of Alzheimer's. This association does not appear to be due to changes in overall brain size or damage to white matter, suggesting more subtle mechanisms. Researchers emphasize the need for further investigation, but the finding highlights the importance of managing blood sugar, especially after meals, as a potential prevention strategy.
