The word "fiber" on a snack bar label doesn't tell you much on its own. For people with IBS, the type of fiber matters as much as the amount — because the most common fiber additives in conventional bars are well-documented IBS triggers.

Inulin, chicory root fiber, and FOS are classified as prebiotics, but for a sensitive gut, the fermentation they cause is too fast and too aggressive — producing the gas, bloating, and cramping that define a bad fiber bar experience. Many people assume all fiber bars will cause symptoms. That assumption is fair, but it's sourced-specific, not category-wide.

Fody's bars are built around a slower-fermenting prebiotic fiber blend — whole grains, seeds, and nut butter — that delivers 6g of fiber per bar without the fermentation cascade. For IBS-C, that supports regularity. For IBS-D, it avoids the rapid motility trigger. FODMAP Friendly certified and safe during elimination, these bars work for both types without the guesswork.
