Question: what is the difference between nonfat and skim milk?
Answer: According to the U.S. Food and Drug Administration, the term nonfat milk means skim milk, nonfat dry milk, concentrated skim milk, or reconstituted skim milk. Therefore, nonfat milk and skim milk are the same thing. In fact, some brands of nonfat milk list both "fat-free" and "skim milk" on the nutrition label.
