The kind of fruit you choose to enjoy matters little in terms of blood glucose control. Rather, it is how much fruit you choose to enjoy. Each serving of fruit contains about 15 grams of carbohydrate. For example, a serving would be one small apple, 1/2 cup canned fruit, 1/4 cup dried fruit, or 4 ounces of fruit juice.
It is how you fit fruit into your daily meal plan that will provide the best control. As a general rule, you should get about 3 servings of carb (or 45 grams of carbohydrate) at each meal. This carb number may be more or less depending on your weight goals and drug regimen.
Fruit is a source of carbohydrate so it will affect your blood glucose; the trick is to eat it in moderation.
