Whole fruit in general is an important part of a healthy diet for people with diabetes, but citrus fruits, apples, grapes and blueberries are particularly helpful, according to Everyday Health. Fruit does have sugar in it, but it also has anti-oxidants and fiber in it, both of which aid health.
While whole fruits are good for diabetics, fruit juices elevate sugar. A piece of whole fruit has the same sugar as about 4 ounces of fruit juice, on average, which is a healthy amount in most cases. However, a 12-ounce glass of fruit juice often has too much sugar for the typical diabetic, as stated by Everyday Health.
Anti-oxidants present in fruits help fight cell damage. When oxidation hits cells, the damage can spread quickly and contributes to some of the complications of diabetes. Anti-oxidants fight this damage and are most common in fruits with bright colors. Fiber is important because it helps people feel full without contributing additional sugar to the diet. Fiber is impossible to digest, but it still adds bulk to the digestive tract, sating hunger. Maximizing fiber from fruit requires eating fruit while the peel or skin is still on it, when possible, reports Everyday Health.
