The Low FODMAP diet might be what your referring to. I know I have found it helpful in many ways.

I've been trying to do the diet mentioned in the "Endometriosis Health and Diet Program" - it's a book written by an Endometriosis clinic owner and it not only answered a load of questions i had, from whether a hysterectomy would help to beneficial supplements, but it also details an extreme diet he puts every patient on that lowers the inflammatory state every Endo patient is in. Even if the diet doesn't sound good, the info contained within was AMAZING!

The Mediterranean diet is good and Turmeric for the whole body has been a huge help for me.

Try to avoid really fatty foods and too much salt. Fatty foods do not agree with me most days and salty foods can make me bloated.

This cookbook has really helped! I've noticed the anti inflammatory diet really helps tone down my IBS symptoms and inflammation overall. Still in pain but it helps.
