Improving the overall quality of one's diet helps to prevent type 2 diabetes, independent of other lifestyle changes.
This is according to a study presented at the American Diabetes Association's 74th Scientific Sessions®. The study, by researchers at the Harvard School of Public Health, 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. Dietary quality was measured using the 110-point Alternate Healthy Eating Index 2010.
The study also examined whether improved diet was a marker of other lifestyle changes, such as weight loss or increased physical activity, or if it could independently reduce a person's risk for developing type 2 diabetes.
The study also showed that it didn't matter how good or poor a person's diet was when they started out, she said. "Regardless of where participants started, improving diet quality was beneficial for all."
