While kidney beans also contain antioxidants, the amount is generally lower compared to black beans.
Can I use kidney and black beans interchangeably in recipes?

If you’re substituting kidney beans for black beans in a recipe, you may need to adjust the cooking time and liquid accordingly. Kidney beans tend to absorb more liquid and cook more quickly than black beans, so you may need to reduce the cooking time and liquid to prevent them from becoming mushy. On the other hand, if you’re substituting black beans for kidney beans, you may need to increase the cooking time and liquid to ensure they’re tender.
