albumin, raw or half-cooked meat is said to be more digestible than cooked meat; but meat that is not thoroughly cooked is dangerous because it may contain trichinæ ("Animal Biology," p. 50) and other parasites. Lean meats contain much proteid. Some persons who cannot easily digest starch and sugar because of fermentation eat fat for a fuel food. Beef tea and beef extracts contain but a small part of the proteid in meat and all of the waste matter, including urea.
