Black beans (cooked) vs Kidney beans (cooked)
Two cooked beans, very close on calories, protein and fibre. Black beans are softer with an earthy taste; kidney beans are firmer and hold their shape in chilli and stews. Near-interchangeable — pick by the dish and the texture you want.
Black beans (cooked) and Kidney beans (cooked), per 100 g and per portion. A gap means USDA has no value for it — not zero.

Generic USDA foods (not brands), so both carry micronutrients. Numbers are per 100 g unless the portion toggle is on. USDA FoodData Central, as of 2026-08-12.
Is Black beans (cooked) or Kidney beans (cooked) better?
Neither is “better” on its own — it depends what you want from it. The table shows where each is higher; the short answer says when each one fits. Compare on the same basis (per 100 g) and pick for your dish and your goal.
How were these numbers worked out?
Straight from USDA FoodData Central for the generic form of each food, per 100 g. We show the portion view too, but portion sizes differ between foods, so per 100 g is the fair comparison.
Why does one column say “no data”?
Because USDA has no value for that nutrient in that food — so we leave it blank rather than print a 0 that would read as “none”. A real zero from USDA still shows as 0.
