In the United States, 23.6 million children and adults — 7.8% of the population — have diabetes and one-third of U.S. adults are obese [1-2]. Obesity is associated with an increased risk of developing type 2 diabetes as well as insulin resistance, a condition that precedes the development of type 2 diabetes. New research published in the Journal of Nutrition now suggests that blueberries can help improve insulin sensitivity in obese, non-diabetic and insulin-resistant people [3].
