People who eat more leafy greens like spinach and kale tend to have a lower chance of getting type 2 diabetes, according to studies tracking thousands of adults over many years.

Even when researchers looked at different groups of people, different ways of measuring diet, or different countries, eating more leafy greens still seemed to be linked to lower diabetes risk, which makes the finding more reliable.

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.

Leafy greens might help prevent diabetes because they contain good nutrients like magnesium and antioxidants that help your body use insulin better and fight cell damage.

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.

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.
