The researchers point out several benefits from eating fruits and vegetables, which may also decrease the risk for diabetes. Soluble fiber in the stomach and small intestine can slow down absorption of nutrients and therefore may prevent the rise in blood glucose levels and subsequent insulin levels. Fruits and vegetables contain minerals, including magnesium.
Magnesium plays a role in the production of insulin.
Other components of fruits and vegetables, including antioxidants, vitamin C, and vitamin E also appear to lower the risk for diabetes. According to the American Diabetes Association, people with diabetes should increase their intake of vegetables. Not only are vegetables full of vitamins and minerals, but they also are low in calories. The proper amount of daily fruit intake depends on the individual. The body's response to fruit and fruit juice varies from person to person.
