Who should avoid foods containing inulin?

Ms. Ashley Koff, RD
Nutrition & Dietetics
Inulin is a polyfructose (meaning several fructose chain) or fructan carbohydrate, and from a nutrition standpoint is known for its fiber and prebiotic benefits.

Based on inulin's ability to cause digestive distress in some, I would recommend avoiding inulin (in its food sources and as an ingredient) if you suffer from gastrointestinal issues -- celiac disease, Irritable Bowel Syndrome (IBS), candida (no sugar), SIBO (small intestinal bacterial overgrowth).

It has been speculated that people fall into one of three categories regarding sensitivity to inulin:
1) nonsensitive persons can consume 30 g/d (grams per day) or more of the compound with little or no symptoms as described;

2) sensitive persons can consume 10 g/d of the compound without discomfort but might experience undesirable reactions with doses of 20 g/d;

3) very sensitive persons can experience symptoms of intolerance at doses as small as of 10 g/d.
