When choosing a juice be VERY CAUTIOUS! The recommendations of juice consumption for children is 4-6 ounces per day. Most household cups are 16 ounces in size. Lots of empty calories are consumed just in juice consumption.
For example, if you were to drink a tall glass of the regular cran-grape juice shown above (thinking that cranberry is really healthy for you), you would be consuming 240 calories & 62 grams of sugar--> equivalent to almost a small meal!
