Kidney Beans or Black Beans – Which is Healthier?

Our Verdict

When comparing kidney beans to black beans, we picked the black beans.

Why?

First, do note that black beans are also known as turtle beans, or if one wants to hedge one’s bets, black turtle beans. It’s all the same bean. As a small linguistic note, kidney beans are known as “red beans” in many languages, so we could have called this “red beans vs black beans”, but that wouldn’t have landed so well with our largely anglophone readership. So, kidney beans vs black beans it is!

They’re certainly both great, and this is a close one today…

In terms of macros, they’re equal on protein and black beans have more carbs and/but also more fiber. So far, so equal—or rather, if one pulls ahead of the other here, it’s a matter of subjective priorities.

In the category of vitamins, they’re equal on vitamins B2, B3, and choline, while kidney beans have more of vitamins B6, B9, C, and K, and black beans have more of vitamins A, B1, B5, and E. In other words, the two beans are still tied with a 4:4 split, unless we want to take into account that that vitamin E difference is that black beans have 29x more vitamin E, in which case, black beans move ahead.

When it comes to minerals, finally the winner becomes apparent; while kidney beans have a little more manganese and zinc, on the other hand black beans have more calcium, copper, iron, magnesium, phosphorus, potassium, and selenium. However, it should be noted that honestly, the margins aren’t huge here and kidney beans are almost as good for all of these minerals.

In short, black beans win the day, but kidney beans are very close behind, so enjoy whichever you prefer, or better yet, both! They go great together in tacos, burritos, or similar, by the way.
