Clean eating
Clean eating is an informal way of describing a diet built mainly around minimally processed, nutrient-dense foods. It has no standardized scientific definition: one person may simply mean eating more vegetables and home-cooked meals, while another may use the label for a long list of prohibited ingredients.
Processing alone does not determine whether a food is nutritious. Frozen vegetables, canned beans, pasteurized milk, tofu, whole-grain bread, and protein powder are all processed to some degree and can fit a balanced diet. Conversely, a food marketed as natural or "clean" can still be low in fiber, protein, or important micronutrients. Food safety, nutritional value, convenience, and degree of processing are related questions, but they are not interchangeable.
For strength training, the useful part of the idea is usually its emphasis on a varied dietary pattern. Meals that provide enough energy, protein, carbohydrates, fats, fruit, vegetables, and fluids can support training and recovery. Results do not depend on making every ingredient fit a purity rule. The World Health Organization's healthy-diet principles focus on adequacy, balance, moderation, and diversity rather than a clean-versus-dirty classification.
A practical interpretation is to make nutrient-rich foods convenient and frequent while leaving room for foods chosen for taste, culture, price, or social occasions. Calling foods clean, dirty, good, or bad can turn a flexible pattern into moral judgment. If the label produces anxiety, guilt, compulsive checking, or cycles between restriction and a cheat day, dropping the label may be more helpful than tightening the rules. A sustainable meal plan is defined by what it supplies and whether it works in real life, not by a purity standard.
