Among the 54 legumes in the database, pork and beans ranks 29th by protein per serving, and 275th out of all 796 foods on the site. Set against black gram (urad dal), another legume entry in the database, a serving carries about 0.5 g less protein (black gram (urad dal) has 13.6 g per 1 cup cooked).
It is an incomplete protein on its own; pairing it with other plant foods across the day covers the full range of essential amino acids. The serving above is measured by volume at 253 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
