Irritable Bowel Syndrome (IBS) “is a functional disorder of the large intestine (colon)” (Light, 2006, p. 187).  When food is introduced, the colon contracts and expands rhythmically in order to move the food along.  When the colon is irritated, the contractions are longer and stronger producing bloating, gas, abdominal pain, cramps, and bowel changes.  Although diet is not thought to cause IBS, certain food can irritate IBS.

According to Carolyn Dean, “a Canadian medical and naturopathic doctor, herbalist, acupuncturist, and nutritionist, and the author of Irritable Bowel for Dummies,” (p. 192) IBS is a result of an over-growth of yeast in the intestines.  Foods that contribute to an over-growth of yeast include, “sugars from milk, fruit, and honey as well as refined sugars and industrial sweeteners in commercial foods and drinks” (p. 193).  Furthermore, certain foods may trigger IBS.  They include:  aspartame (artificial sweetener), sorbitol, fatty foods, coffee, gluten, fructose, and dairy products.  Keeping a food dairy may help you uncover the foods that are triggering your irritable bowel.  Also, eating smaller amounts at a time, more frequently, and a fiber-rich diet may be helpful.
