The beneficial effect of the dietary pattern on diabetes mellitus and glucose metabolism in general and traditional food pattern was associated with a significant reduction in the risk of developing type-2 diabetes. The dietary pattern emphasizes a consumption of fat primarily from foods high in unsaturated fatty acids, and encourages daily consumption of fruits, vegetables, low fat dairy products and whole grains, low consumption of fish, poultry, tree nuts, legumes, very less consumption of red meat.[18,19,20] The composition of diet is one of the best known dietary patterns for its beneficial effects on human health that may act beneficially against the development of type-2 diabetes, including reduced oxidative stress and insulin resistance. High consumption of vegetables, fruits, legumes, nuts, fish, cereals and oil leads to a high ratio of monounsaturated fatty acids to saturated fatty acids, a low intake of trans fatty acids, and high ingestion of dietary fiber, antioxidants, polyphenols. The diets are characterized by a low degree of energy density overall; such diet prevent weight gain and exert a protective effect on the development of type-2 diabetes, a condition that is partially mediated through weight maintenance. Greater adherence to the diet in combination with light physical activity was associated with lower odds of having diabetes after adjustment for various factors.[21,22,23,24,25] On the other hand, a paleolithic diet (i.e., a diet consisting of lean meat, fish, shellfish, fruits and vegetables, roots, eggs and nuts, but not grains, dairy products, salt or refined fats, and sugar) was associated with marked improvement of glucose tolerance while control subjects who were advised to follow a diet did not significantly improve their glucose tolerance despite decreases in weight and waist circumference.[26,27,28] People most likely to get diabetes are: People who are overweight, upper-body obesity, have a family history of diabetes, age 40 or older, and women (50% more often than men).
Getting to—and staying at—a healthy weight: Being overweight (BMI greater than 25 kg/m2) increases your risk of developing type 2 diabetes, so if you’re overweight, you should take steps to lose weight. By losing 5% to 10% of your body weight, you can reduce your risk. You can do this by eating smaller portions and being more physically active, which, conveniently enough, are two other ways to prevent type 2 diabetes.
Foods might sometimes appear to be packaged into individual serving sizes even though they contain two or more servings per package. To determine that, look at "serving size" and "servings per container" at the top of any food label. For example, if a serving size is 1 and there are 2 servings per container, you will need to double all of the nutrient values on the label in order to get a clear picture of the value of the entire container.
