I suffered with IBS since I can remember, I'm now 34 years old. IBS is not a disease, and it can be fixed. The problem is that we eat a lot of processed food that our bodies can't handle. Since I went paleo (only natural foods, no processed food, no dairy, no wheat, no grains) IBS went away. I was amazed at this as the doctors told me that it was anxiety related. They also told me to eat more grains and fibre, however this had the opposite effect.

I would recommend anyone with IBS to elimate certain foods from the diet starting with wheat, dairy and grains and see if that helps.
