How were these foods ranked?
Basis: protein in one serving of each food, in the portion its USDA record is quoted in. Those portions are not a common unit - a cup of dry milk powder is not the same amount of food as a chicken breast - so every row prints its serving and its weight, and the per-100 g list compares the same foods on equal weight. 11 of the 796 foods in the ProteinTally database are protein supplements. Figures come from each food's USDA record.
