Exercise May Boost Beta Cell Function
The high blood glucose levels in type 2 diabetes are triggered by the body's resistance to insulin and the failure of the beta cells in the pancreas to make enough insulin to overcome this resistance. A study found that exercise may help stave off type 2 diabetes by improving beta cell function. Researchers asked 1,152 Mexican Americans about their physical activity, and took blood samples to analyze their beta cell function and levels of glucose and insulin. They found that people who said they exercised more had better beta cell function, independent of weight, diet, and body fat.
