Nutrtion Science Q & A

While fruit juice is often touted as being a healthy, natural food, it has both positive and negative effects in terms of bodybuilding. On the negative side, fruit juice is a refind carbohydrate, which relates to the fact that most fruit juices lack fiber. As a result, they have higher glycemic-index ratings than their whole fruit counterparts, which do contain some fiber. The fiber in whole fruits, coupled with their fructose content, usually leads to slower carbohydrate absorption and, subsequently, lower glycemic-index ratings than juices have.
