My mother has diabetes and she has been managing it for years.Up till now,researchers don't fully understand the cause of diabetes but it is clear that some factors increases the risk. Being overweight is a risk factor for diabetes.If your body store fat in your abdomen, then you are at risk.The less active you are in exercising, the higher your risk.Also,your risk of diabetes increases if your parents or siblings have it.It is still unclear why some race have more people with diabetes than other race.Your risk of diabetes increase as you grow older. Now to your question, the fact is that new studies are accessing the effect of anthcyanine on diabetes.Fruits rich in anthocyanine were used in conducting the research and it was discovered that higher consumption of anthocyanine and anthocyanine rich fruit lowers the risk of type 2 diabetes.The findings showed an association but did not prove that the fruits themselves prevent diabetes. I suggest you talk to a qualified medical personnel. Of all the risk factors mentioned above,almost two third of them can be minimised by making healthy eating decisions and exercising.Balanced eating diet low in fat,saturated fat,simple sugar and cholesterol combined with an active lifestyle can decrease your chance of developing type 2 diabetes Bottom line- Continue filling half your plate with tasty,beautiful, nutrient packed fruits with veggies.
