Blood Sugar Spikes Linked To Alzheimer’s Disease

Blood Sugar Spikes Linked To Alzheimer’s Disease | Dr. Weil
30 seconds

A recent investigation from the University of Liverpool suggests that sharp spikes in blood sugar after meals may significantly increase the risk of Alzheimer’s disease. Using genetic and health data from over 350,000 UK Biobank participants ages 40 to 69, researchers examined different measures of blood sugar control, including fasting glucose, insulin levels, and post-meal blood sugar.

Using a type of genetic analysis, the team found that people who tended to have higher post-meal (postprandial) blood sugar levels also had a 69 percent higher risk of developing Alzheimer’s disease. This link was not explained by general brain shrinkage or white-matter damage, indicating that elevated after-meal glucose may harm the brain through more subtle mechanisms. The findings build on existing evidence connecting diabetes and insulin resistance to cognitive decline and suggest that managing blood sugar spikes after eating could be important for long-term brain health.
