My husband has diarrhea, sometimes violent, shortly after eating some foods. This used to happen to him only after eating out somewhere with a salad bar, or if he had homemade ice cream with raw eggs. Recently it also occurs with onions, jalapenos and some spicy foods. I garden and cook most meals. He is under a HUGE amount of stress with his occupation. His brother and dad also have this condition. I would appreciate any thoughts. Thank you.
