Low FODMAP
Low FODMAP is a temporary elimination protocol designed to identify which fermentable carbohydrates trigger digestive distress in people with IBS. FODMAP stands for Fermentable Oligosaccharides, Disaccharides, Monosaccharides, And Polyols.
Why It Matters
Many common protein powder ingredients are high-FODMAP and can trigger bloating, gas, or diarrhea in sensitive people. Lactose (in whey concentrate), inulin, chicory root fiber, polyols like sorbitol and maltitol, and beans-derived proteins are common offenders.
Whey isolate is generally low-FODMAP because most lactose has been removed. Egg white protein and rice protein also tolerate well. Pea protein is medium; some tolerate it, others react. The Monash University FODMAP app has tested specific products.
How to Spot It on a Label
Few protein products carry an official Monash low-FODMAP certification. Instead, scan the deck for the usual triggers: lactose, inulin, chicory, fructooligosaccharides (FOS), and sugar alcohols other than erythritol. If you tolerate dairy fine but bloat on bars, polyols are often the culprit.
