If a product boasts "100% juice" on the bottle, this means that it was made entirely from fruits and vegetables. However, this doesn't mean that it was made solely from the fruits or vegetables mentioned on the package. Apple, pear, and white grape juice are often added to other fruit juices because they're among the most affordable options.  Check the label to find out what fruits and vegetables are in your drink. Ingredients are listed in order of weight, so those listed first have the greatest weight in the final product. A 100% fruit juice doesn't contain any added ingredients, so you'll only find natural sugars, vitamins, and minerals that come from the fruit itself.
