The number of servings of fruit that a diabetic can eat depends on the person's diet, according to Diabetes.org. Those who are using the glycemic index method are encouraged to eat a lot of fruit, because most fruit has a low glycemic index.
Those people, who are counting carbohydrates should be more careful about fruits, as a small piece of fruit or 1/2 cup of frozen or canned fruit has about 15 grams of carbohydrate. Therefore, in this diet a diabetic should eat fruits in exchange for other sources of carbohydrate in the meal plan, says Diabetes.org.
Overall, it is important to include fruits in the diet, as they are an important source of vitamins and minerals, and most of the sugar in them is in the form of fructose.
