Putting nutrition numbers in context

Energy estimates, protein references and food patterns describe different parts of nutrition. A calorie calculation estimates energy use; a protein conversion applies a published reference to body weight; a macro calculation converts a chosen percentage split to grams. Read the source labels and assumptions before comparing results.
