google “microscopic colitis support” for a well established online support group related to MC. The url is http://www.perskyfarms.com. They encourage gluten-free diet and have lots of recipes and information regarding what is gluten-free and what is not.

IMHO soy is more prevalent and hidden in our foods and therefore more difficult to eliminate from the diet than gluten.
Some people have good results controlling their flares using Pepto Bismol and/or Immodium. Some take Entocort.

I went gluten free about 6 mos ago and it was a big adjustment, but you get used to it. And the results for me have been dramatic so I’m not tempted by bread anymore.
Best of luck. You can get your life back.
