Some foods naturally contain sugar—fruits, 100% fruit juices, milk and other dairy products, and even vegetables. This sugar, perhaps because it is combined with other nutrients (fiber, protein, fat), seems to be processed differently in the body. We know this because gastric bypass patients who get sick (dumping syndrome) from added sugars generally tolerate these naturally-occurring sugars. These foods also contribute important nutrients to the diet and, in the right balance, are part of a healthy diet.
