If your pouch is misbehaving due to sugar/carbohydrates in your diet then all sources of sugar are equally problematic: sweetened beverages, fruits, desserts, starches, etc. There’s not a special exemption for “good” sugar. I tried a *very* (close to zero) low carbohydrate diet for a while, and didn’t see any benefit, but others here have had much better results. It takes a while to help, if it’s going to help.
