British scientists have found a brain mechanism they think may drive our desire for glucose-rich food and say the discovery could one day lead to better treatments for obesity.
In experiments using rats, researchers at Imperial College London found a mechanism that appears to sense how much glucose is reaching the brain and prompts animals to seek more if it detects a shortfall. In people, the scientists said, it may play a role in driving our preference for sweet and starchy foods.
Glucose, a component of carbohydrates, is the main energy source used by brain cells.
