Orange juice is a popular beverage produced from the juice extracted from oranges. It is a good source of vitamin C and has a refreshing, sweet-tart taste. While orange juice can be a healthful beverage due to its vitamin C concentration, it is also heavy in natural carbohydrates. Moderation is essential with any meal or beverage. Choosing 100% pure orange juice with no added sugars or preservatives is also a healthier alternative.
