Beans are high in fiber so I'm thinking adding all that. I think the part of slippery elm that helps is fiber like compound. Let me check. http://www.1001herbs.com/slipperyelm/
they use words like mucilage and long chain polysaccharides which at least is fiber like (think guar gum that is in benefiber) I'm not sure how much of that fiberous inner bark (one other site used fiberous) you break down before it gets to the colon so it might count as fiber, but they mostly describe it as a gel, but I'd guess you are getting a lot more fiber from the beans. The stuff in slippery elm is supposed to help things slide along smoothly so it might be OK even if other fiber bothers you, but if you can't have any fiber at all it might not be good for you. But I'd see how it is without the beans.Let me see if I can get a comparison. OK, I can't get a how many mgs of slippery elm that makes a gel (like guar gum does) but most of the pills have like 0.3 grams of the the slippery elme so we are not talking a whole lot you might check the labels of what you are taking.. A 1/2 cup of cooked kidney beans has about 7 grams of fiber. That was where I wondered about maybe adding too much fiber all at once. You said a lot of beans, didn't you?I use www.fitday.com
to track my diet (where I checked the kidney beans) it has a lot of foods in there and will tell you how much fiber is in a serving as well as calories and fat and all that and it is a free account to get all that info.Checked on there and a brown rice cake has just under half a gram of fiber. Most foods have to put the fiber grams on the label so you might want to check those if you don't tolerate fiber very well.Whole grains (like brown rice), legumes (like beans and dried peas) are both pretty good sources of fiber in the diet.K.
