Try PHGG or acacia fiber for sensitive guts
4
What to Do
If standard fiber sources cause excessive gas or bloating (common with inulin and FOS), try partially hydrolyzed guar gum (PHGG) or acacia fiber. Both are well-tolerated, slow-fermenting prebiotic fibers.
Why It Works
PHGG improves IBS symptoms and increases Bifidobacteria while being FODMAP-friendly. Acacia fiber is 100% soluble and ferments slowly, producing significantly less gas than fast-fermenting fibers like inulin. Both dissolve easily in liquids with minimal taste or texture change.
Tips
- PHGG (brand: Sunfiber) dissolves completely and is virtually tasteless
- Acacia fiber (brand: Heather's Tummy Fiber) is popular in the IBS community for its gentleness
- Ideal for people following a low-FODMAP diet who still want prebiotic benefits
- These are supplements — they complement but do not replace whole food fiber sources
