A fiber question


#1

In my DIY, i have 28 grams of fiber. 10 of which are insoluble and 3.5 of which are soluble. my question is, what makes up the other 14.5 g of fiber? is this some sort of error in the DIY tool/USDA database, or is there a third kind of fiber, and should this third kind be taken into account when considering the optimum ratio of fibers?

I tried looking around on the forum, but didn’t see this specific question so forgive me if I missed someone already answering this.

From what I remember the problem lies with the database. The USDA only tracks the total fiber not what kind of fiber. It also doesn’t track a number of other micronutrients.
