4. Blueberries
A recent study found that blueberries can help to increase sensitivity to insulin and may actually reduce the risk of developing diabetes in those who are predisposed to the condition. Why? – Because blueberries naturally contain a bioactive ingredient that combats high blood sugar and aids those who have insulin resistance.
In addition to being a great food for managing blood sugar levels, blueberries are also full of antioxidants, which fight the damage that is caused by free radicals, thus preventing the onset of a variety of health conditions.
