Serving Sizes and Diabetes

Watching your serving sizes can help you keep the complications of diabetes in check. A dietitian can advise you on how many servings from each food group you should eat per day. But how much is a "serving size?"

The amount of food that is counted as one serving is listed below. If you eat a larger portion, count it as more than one serving. For example, a dinner portion of rice using the chart below is 1/3 cup. The amount you eat may be 1 cup. This would count as three servings from the breads and starch group.
