Diabetes has become a major epidemic in the United States. In 2012, 29.1 million Americans had type 2 diabetes and it is projected that there will be 1.4 million new cases each year. Having diabetes is a major risk factor for cardiovascular disease, renal disease, blindness and limb amputation. Due to the debilitating effects and complications diabetes can have on one's body, research has been conducted to find the best ways to prevent this chronic illness.Diet tends to be a primary focus around diabetes prevention. A Mediterranean-style diet has been suggested as a good diet plan to prevent type 2 diabetes. A Mediterranean diet consists of high consumption of fruits and vegetables, whole grains, legumes and nuts, moderate intake of seafood and poultry with very minimal intake of red meat. Olive oil is the primary source of fat as well as a moderate intake of wine with meals. The diet suggests avoiding foods with added sugars, refined grains, Tran's fats and anything highly processed. According to the literature, this diet can be used to prevent and also help control already diagnosed diabetics.A review of the literature was performed to determine if there is enough evidence to support recommending a Mediterranean diet as a method of preventing and managing type 2diabetes. The literature shows an overwhelming trend that following a Mediterranean diet can help lower the incidence of type 2 diabetes and reduce haemoglobin A1C in those already diagnosed.
