Every 100 kcal of canned pinto beans brings 6 g of protein. On that measure it ranks 30th of the 54 legumes in this database and 411th of all 796 foods on the site. Measured by weight instead, its 7.04 g per 100 g ranks 42nd in its group.
Around 24% of the calories in canned pinto beans come from protein, so it is moderately protein-dense. It contributes to a day's protein total, but the bulk of what it delivers is energy rather than amino acids - treat it as a contributor alongside a denser source, not as the protein in a meal.
Weight for weight, canned pinto beans has 7.3 g of protein for each gram of fat (7.04 g against 0.97 g per 100 g).
Set against canned black-eyed peas, another legume entry in the database, a serving carries about 0.5 g more protein (canned black-eyed peas has 11.4 g per 1 cup).
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 quoted here is measured by volume at 169 g, and it covers about 24% of the 50 g FDA Daily Value for protein.
