Looking for causes still... About 2 years ago, when I first started seeing symptoms of IBS, G and D. I was on a very high fiber diet and high calorie diet too. I was working out a lot, running lifting weights, was very fit but heavy.By high fiber I mean tons of cabbage, veggies of all kind, huge salads, stuff like that. I still ate healthy meals too, but the high fiber was everyday for months. Now from research, I hear that bad bacteria feeds on undigestible foods (fiber) and there are studies saying that high bacteria count is linked with IBS. Also, is it possible I could have damaged my digestive tract with too much fiber? I had some pretty explosive "movements" at the time. I thought it was great, very cleansing, but looking back maybe it wasn't all that good. Any thoughts?
