Thanks for your suggestion Winterberry.
Before my low potassium results, I didn't necessarily eat a potassium enriched diet, but when taking a closer look at the everyday food I do eat, they are certainly not lacking potassium.
I actually eat well and other than porridge oats, no food aggregates my J pouch, in fact, neither does the porridge, it just affects my output
I eat more bananas now, otherwise my diet is very much the same as always.
