5 Principles of Clean Eating
1. Limit Processed Food
Some packaged foods—like yogurt or bagged greens—are "clean." To pick healthy processed foods, look for whole foods in ingredient lists. If an ingredient sounds suited for a chemical lab, think twice. Another benefit to limiting processed food: in a study in Food & Nutrition Research, people who ate a "whole food" sandwich (Cheddar on multigrain bread) burned about 64 more calories per meal than those who ate a "processed" sandwich (processed cheese on white bread). The energy needed to digest a less-refined, more nutrient-dense sandwich may explain the extra calorie burn.
