You’ve probably heard of clean eating, but you may not know what it is exactly or how to go about cleaning up your diet. Eating clean is a good way to refresh your eating habits: it’s about eating more of the best and healthiest options in each of the food groups—and eating less of the not-so-healthy ones.
