It's a common misconception that fruit juice is a healthy option, when it is mostly sugar with little nutritional value. The further away from a natural product you get - through processing, storing, preserving, etc - the less nutrition it will have.
An apple gets an A on this site because it provides nutrients and fiber, with no fat and a reasonable amount of calories: bit.ly/Zgaica
Compare that with 100% Apple juice, which gets a D because it has as much sugar and calories as a serving of regular cola soda, with almost no nutritional benefit: bit.ly/13dCbWa
Foodfacts.com Suggests: try a slice of fruit, like a lemon, in a bottle of water for a healthy and delicious refreshment; juice should be in the same category as soda - an occasional treat!
