Diabetics can include fruit and fruit juices in their diets but must pay attention to the glycemic index of fruits because of their high carbohydrate count. When drinking juice, those with diabetes must watch out for added sugars and pay attention to portion size, states the American Diabetes Association.
Berries, apples, pears and oranges are all good choices for diabetics because they have a low glycemic index, meaning they affect blood sugar levels slowly. Fruits with a low glycemic index provide plenty of fiber and nutrients, particularly vitamins A and C, Everyday Health explains. Fruit juices don't provide any fiber and consequently tend to cause blood sugar to spike. This can be dangerous for people with diabetes, who should consume fruit juices in small quantities of 4 ounces or less.
Fresh and frozen fruits are good choices for diabetics, per the American Diabetes Association. Those who count carbohydrates should keep to 15 grams of fruit per serving; this is the equivalent of 3/4 to 1 cup of fresh berries or cut melons, 1 small piece of whole fruit, 1/2 cup of cut fruit, or 2 tablespoons of dried fruit. Those who keep track of the glycemic index of foods they eat should be aware that melons, pineapples and many dried fruits don't have a low glycemic index.
