Danger of Post-meal Blood Sugar to Brain

[kit_hung]

A large genetic study has shown that a spike in blood sugar after eating may be more harmful to the brain than previously thought. People with higher postprandial sugar levels were found to have a higher risk of developing Alzheimer's disease.

Surprisingly, this effect could not be explained by direct damage to the brain, suggesting that there are hidden biological mechanisms involved. The researchers say that controlling postprandial sugar could be an important strategy to reduce the risk of dementia.
