I got through my Celiac Disease and horrible leaky gut (sensitive to about 30 different foods) on the SCD Diet. You really can get a handle on all it through diet, but it takes a strong committment to want to get better.
Check into both, both diets are really effective at healing your gut. Pick one and run with it with 100% commitment and you will see results pretty quickly.
If you want some more help I have a free guide about how to properly start the SCD Diet based on how I did it. You can get it at http://www.scdlifestylebook.com/free.php
Send me a PM if you need anything or have any questions about my experiences with the diet.
