White Potato Pain Dairy Replacements?

Dairy replacements? - white potato pain

I have been with IBS and gave me some good advice in yaws antispasmodic, but there are certain foods trigger the pain. I had dairy products, pasta and rice, bread and potatoes, sliced

I'm OK deal, without bread, potatoes, milk and cheese, which I miss

Is there anything that will be used as a substitute, which can taste bad or have the same taste. Soy milk is not just right.

Elce nothing that I can be used for bread making as a replacement, etc. would also be good, I rice and pasta that works well use
