Most soluble fibers are fermentable. However, some fibers such as inulin ferment quickly while others like acacia ferment slowly. The FODMAP diet focuses more on carbs and fibers that ferment rapidly which are the short-chained carbs and fibers.
Only a few soluble fibers like inulin are FODMAP unfriendly and these ferment rapidly. Given that most FODMAPs ferment rapidly in the colon and acacia is not a rapidly fermenting soluble fiber it is likely considered FODMAP friendly.

I noticed that my probiotic actually includes inulin - probably as a binding agent. I suspect I should avoid this during the FODMAP elimination diet, even though it's a small amount.
