I am a retired female and in my early 70's. Have always been very active and healthy. Eating healthy is a priority with me. Exercising and staying fit. My gut problem started about five years ago and I had my gallbladder removed. Shortly after that, about 4 months I started having severe runs with every thing I ate. I started eliminating foods while the Dr. took all the necessary test. I ended up eating only rice and drinking rice milk. Dairy and soy were two of the bad guys. Lost a lot of weight. Since then I have added back more foods. Dairy, soy, beans, pumpkin, banana, squash, some nuts, fatty meat to mention a few are the ones I stay away from. My gut is not back to where it used to be but I am getting used to a new normal. Probiotic supplements is important to me. I have found it confusing to say the least to try to pick one that's going to work for me. So happy that I signed up with the Mayo Clinic Web and I will be reading all of your inputs.
