Smoothie King's Peanut Power Plus Grape Smoothie

Smoothie King combines peanut butter, banana, sugar, and grape juice in its Peanut Power Plus Grape Smoothie. A 40-oz. order of the smoothie contains 1,460 calories and three-and-a-half days' worth of added sugar (22 teaspoons). However, some experts believe it might actually be closer to six-and-a-half days' worth, since the 17 teaspoons of naturally occurring sugar in the grape juice aren't any healthier than added sugar. There's also an additional 12 teaspoons of sugar coming from the banana and nonfat milk.
