Is a glass of fruit juice equivalent to a piece of fruit

No. Whole fruit is always the better option: A medium orange contains just 62 calories and 12 grams of sugar, and it has 3 grams of belly-filling fiber. By comparison, an 8-ounce glass of Minute Maid OJ has 110 calories, 24 grams of sugar, and no fiber. What’s more, so-called juices contain not only the natural sugar from the fruit but also copious amounts of added sugars, so that they aren’t as tart. (Cranberry juice, in fact, is too sour to drink when it hasn’t been sweetened.) Plus, even drinks labeled 100 percent pure juice aren’t necessarily made exclusively with the advertised juice.
