Fruit Juice (All Types) Overview

Fruit juice (including orange, apple, grape, cranberry blends, and “juice cocktails”) is a concentrated source of sugar with little fiber. Even 100% juice can deliver a large carbohydrate load quickly, making it unsuitable for low-carb, keto, and generally not diabetic-friendly in typical servings.
