Each and every person needs a different kind of diet and generalized advices are not applicable here. IBS generally affects the digestive tract and both men and women suffer from this problem. By making some small dietary changes, a person can get huge benefits. Smaller meals should be preferred and offending foods must be avoided. Some people suffer from constipation and in their case the breakfast becomes hugely important as it initiates bowel movement. Insoluble fiber, nuts, coffee and chocolate can cause problems and this is why they are not included in IBS diet. Milk is extremely problematic and the fat present in it can cause diarrhea. Beans are capable of giving bathroom nightmares too and they should be totally avoided.
