Adding fiber to your diet when you have IBS sounds straightforward — but the type of fiber makes all the difference between feeling better and feeling worse.
The most common offenders in conventional bars are chicory root fiber and inulin, both added cheaply to boost fiber counts on a nutrition label. Also watch for sorbitol, mannitol, xylitol, honey, agave, and high-fructose corn syrup. These ingredients ferment rapidly in the gut — which is exactly what drives the bloating, cramping, and urgency that make people distrust fiber bars entirely. This pattern is especially common in products marketed directly at digestive health.
Terms like natural, gut-friendly, or high fiber are marketing language, not clinical standards. FODMAP Friendly certified is a meaningfully different claim — it means the complete product, at the actual serving size, has been independently laboratory-tested and validated to meet established FODMAP thresholds. That's the signal worth looking for.
Fiber That Works With Your IBS Diet
When you’re managing a diet for IBS, fiber isn’t the enemy. The wrong fiber type is. Slower-fermenting fibers are better tolerated by sensitive digestion than rapidly fermented varieties, and that distinction is what makes Fody’s High Fiber Snack Bars different. Each bar is made with Solnul® prebiotic fiber (a resistant starch), which feeds beneficial gut bacteria and supports regularity without the fermentation discomfort that makes most people with IBS avoid high-fiber foods entirely.
Gentle Prebiotic Fiber for Gut Health
Most gut health supplements rely on fibers that ferment quickly and can be hard on sensitive digestion. Fody’s High Fiber Snack Bars take a different approach. Each bar is made with Solnul® prebiotic fiber (a slower-fermenting resistant starch) that feeds beneficial gut bacteria and supports regularity without triggering the discomfort faster-fermenting fibers can cause. Tested and certified Low FODMAP and available as a certified Low FODMAP snack bar, these gentle fiber bars deliver prebiotic fiber for gut health the way a daily snack should.
