Among the 31 soy foods in the database, tofu (silken) ranks 22nd by protein per serving, and 444th out of all 796 foods on the site. Set against meatless deli slices, another soy food entry in the database, a serving carries about 0.8 g more protein (meatless deli slices has 5 g per 1 slice).
It is a complete protein - it supplies all nine essential amino acids in adequate amounts, so it can carry a meal's protein on its own. The serving above is counted by piece at 84 g. Because pieces vary, the per-100 g figure is the one to use when comparing this against a food measured a different way.
One of the few plant foods that is a complete protein, with all nine essential amino acids.
