Doctors reviewed three large studies that measured diabetes and anthocyanins in the diets of 200,894 people, and five large studies that measured diabetes and berries in the diets of 194,019 people.
For anthocyanins overall, compared to men and women who got the least, men and women who consumed the most anthocyanins were 15 percent less likely to have developed type 2 diabetes over the several study periods. For every 7.5 mg increase in anthocyanins per day, chances for diabetes declined by 5 percent.
For berries, while there were no effects seen in men, women who got the most berries in the diet were 18 percent less likely to have developed type 2 diabetes compared to women who got the least. Each 17 gram increase in berries per day lowered chances for type 2 diabetes by 5 percent.

Additional Comments from Don Goldberg
Anthocyanins are a type of flavonoid usually associated with plant pigments. Thus, those fruits, berries and vegetables that are highly colored can be expected to have a high content of anthocyanins or their precursors. Examples you are familiar with would include blueberry, pomegranate, grape skin and grape seed, etc. Supplements containing high concentrations of anthocyanin are readily available. Ask the pharmacists or nutritionists at Willner Chemists for guidance in selecting the product that is right for you.
