Improving diet quality reduces risk for type 2 diabetes

Improving the overall quality of one's diet helps to prevent type 2 diabetes, independent of other lifestyle changes, according to a new study. The study found that those who improved their diet quality index scores by 10 percent over four years -- by eating more whole grains, fruits and vegetables, and less sweetened beverages and saturated fats, for example -- reduced their risk for type 2 diabetes by about 20 percent, compared to those who made no changes to their diets.
