About these values

The record is black beans boiled without salt, not canned. The USDA record is "Beans, black, mature seeds, cooked, boiled, without salt" (SR Legacy, FDC ID 173735). It gives 8.86 g of protein and 132 kcal per 100 g.

Protein in a portion is its weight times the protein per 100 g, divided by 100. For 1 cup of cooked black beans: 172 × 8.86 ÷ 100 = 15.2 g. Values on this page are rounded to 0.1 g.

A packaged food's own label can differ from the USDA average. When you have the label, its numbers are the ones for that product.
