Juice drinks contain fruit juice, but at levels less than 100%. Some contain 50% fruit juice or more, while others contain 5% or less. Manufacturers are required to label the percent of real fruit juice in the product.
The nutrient content of juice drinks depends on how much 100% juice is used in the product and on whether any nutrients are added. In the U.S., the nutrition facts panel on juice drink packages provides information on juice content, calories, vitamins and minerals, and other nutrients.
