Hello Jeanne! It's really interesting you picked up on that - I know in the case of certain food groups there is certainly a spectrum of nutritional benefits (for example choosing brazil nuts and walnuts over peanuts for the highest antioxident and omega-3 content), however, I can't find anything in the cited research that would suggest red beans wouldn't be interchangeable nutritionally with any of the other beans! If you happen to recall where else you have seen them neglected, I would be interested to look into it! Thanks for your comment and I'm very glad you enjoyed the article :)
