Blueberries and Insulin

A new study published in the Journal of Nutrition (August 19, 2010) showed that subjects who consumed blueberries twice/day for 6 weeks had an improvement in insulin sensitivity. The participants were all obese and insulin-resistant, but not diabetic.

Blueberries have long been considered a “super-food” because of their high antioxidant and fiber content, and are often recommended for diabetic or insulin-resistant patients due to their negligible affect on blood sugar (as opposed to other fruits). However, the fact that they are now proven to actually reverse insulin-resistance makes it even more important for doctors to emphasize that all patients who are pre-diabetic and/or obese consume blueberries on a daily basis.
