Keep in mind that, in its most basic form, fruit juice is water and sugar. And sugar is sugar, regardless of its source. Additionally, as nutrition facts labels show, the difference in percent juice does not always significantly affect the actual sugar content of the beverage. But not all juice drinks are created equal. Don't assume one brand of juice is just like another, no matter how similar they seem.
Fruits vary in their nutritional contents, and fortification practices vary from company to company.
Never judge a juice solely by its cover because the front of the product rarely tells the whole story. For example, unfortified 100 percent apple juice may contain only 2 percent of the daily recommended amount of vitamin C, while many fortified juice drinks contain 100 percent of the daily allowance in just one serving. Considering that natural sugars from fruit juices are not nutritionally superior to added sugar in juice drinks, look for juices with the least amount of sugar and 100 percent of the recommended daily amount for vitamin C per serving. The FDA does not have a regulation regarding this term. But many manufacturers use it when they sweeten with a fruit juice rather than with sugar.
