Food labels and nutrition facts: What do they really mean?
Nutrition Facts panel: Calories = 40
The manufacturer diluted the calories in this juice with water (and didn’t add refined sweeteners, which is a plus). So, a single-serve pouch contains only 40 calories, versus about 125 calories that you’d get in the same amount of 100 percent grape juice. Although you could accomplish the same thing by diluting grape juice yourself, it’s not as convenient.
