A study presented at the 2014 American Diabetes Association Scientific Session reported that improving the overall quality of one’s diet helps to prevent type 2 diabetes apart from other lifestyle changes.
Researchers at the Harvard School of Public Health found that a 10% improvement in one’s diet quality index score reduced the risk for type 2 diabetes by about 20% compared to those who made no changes to their diets. Dietary quality was measured by the 110-point Alternate Healthy Eating Index 2010. Also, the study assessed whether an improved diet was an indicator of other lifestyle changes such as weight loss or increased physical activity, or if it could independently reduce one’s risk for developing type 2 diabetes.
Diet was associated with diabetes independent of weight loss and increased physical activity. Improvement in the diet quality alone had significant benefits in reducing the risk for type 2 diabetes. Results from the study also showed the diet quality at baseline did not affect the overall benefit of improving diet quality.
