Eating more fruit and vegetables together doesn't seem to lower the risk of type 2 diabetes, according to a review of four large studies tracking thousands of adults over many years.

Eating more vegetables like carrots or broccoli doesn't appear to lower the risk of type 2 diabetes, according to a review of five large studies tracking thousands of adults over many years.

People who eat at least five servings of fruits and vegetables a day — as estimated by blood tests — have about a one-third lower risk of developing type 2 diabetes than those who eat less.

Blood tests for fruit and vegetable nutrients are better at predicting diabetes risk than asking people what they ate, because people often misremember or misreport their diet.

The benefit of eating more fruits and vegetables for preventing diabetes is less strong in older people than in younger ones, possibly because aging changes how the body responds to nutrients.
