Here’s a shocker: the average person takes in 22 teaspoons of sugar daily—more than three times the amount suggested by the American Heart Association. And although it has never been considered a health food, new evidence shows sugar can do even more damage than previously thought, setting you up for obesity, diabetes, and heart disease. But weaning yourself off sugar can be daunting.

Still, slashing sugar is one food trend worth trying. Find out all about sugar rehab, plus tactics to make your commitment stick.
