I recommend using black beans instead.
Finding out your secretor status will help you determine if pintos are acceptable, but I serve black beans to my type O friends since they seem to do better with them (& I do not have to know their secretor status)
I do well on pinto beans, but I second C_sharp's recommendation of black beans. However they might turn a rice & beans casserole into an unappetizing grey color. Adzuki beans (if you can find them) are excellent. I also do well with black-eyed peas. Good luck!
My SWAMI diet is a blend of BTD and GTD Explorer, but I'm not totally compliant. Also I try to choose foods that have a Low Glycemic index. DW and DD are A+, probably also Explorer.
