Food sources of carbohydrates should always be eaten WITH a source of protein and or unsaturated (“healthy”) fat. Fat and protein digest more slowly which helps prevent blood sugar spikes. Examples of balanced snacks that combine carbohydrate foods with protein/fat include, apple with peanut butter; berries with plain Greek yogurt; whole wheat toast with almond butter; baked potato with cottage cheese.
There is much you can do with lifestyle alone to prevent diabetes. In a landmark study, the NIH-sponsored Diabetes Prevention Program, scientists tracked 3,234 pre-diabetic men and women for three years. A third of them adopted lifestyle changes. Another third took a drug – metformin (Glucophage®). The remaining third, the control group, took a placebo. Those on the lifestyle-change plan reduced the progression to full-blown Type 2 diabetes by 58% compared to the control group. The reduction was even greater – 71% – among adults aged 60 and older. Treatment with the drug metformin reduced the progression of Type 2 diabetes by just 31%.

Although sugar does not cause the blood sugar to rise any higher than other carbohydrates, it should be eaten along with other healthy foods. If you choose to drink a 12-ounce can of a sugar-sweetened soft drink, that would use up about 45 grams of carba, and you wouldn't have gotten any nutrition (protein, vitamins, or minerals). What a waste of calories!
Other than gestational (which occurs in pregnant women and usually disappears after giving birth), there are two types of diabetes: Type 1 and Type 2. Type 1 diabetes accounts for only 5 percent of all instances in the United States, according to the Centers for Disease Control and Prevention. Type 2 diabetes is the most common, clocking in as the seventh leading cause of death in the United States. Type 2 diabetes is also the only one that’s considered preventable. It generally develops later in life, sometimes as a consequence of lifestyle or other health factors.
Choose lean sources of protein. Lean sources of protein include: eggs, egg whites, chicken breast, turkey breast, lean beef, pork tenderloin, fish (e.g., cod, tilapia, orange roughy), beans, or tofu. Adding protein to your daily intake helps to control spikes in blood sugar and helps with fullness to prevent unnecessary snacking on poor choices later.
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.
