Ruling out gluten sensitivity is really important, as the symptoms are typically identical to IBS. Unfortunately, unless you do a small intestine biopsy the antibody tests for gluten sensitivity can be unreliable. If the standard antibody test is positive, you indeed have it, but if it’s negative you may still be gluten sensitive. Only by strictly eliminating all gluten containing foods for 4 to 6 weeks can you determine whether you are sensitive to gluten or not.
If you are not gluten sensitive, one suggestion Ms. Hupston makes is that, through the process of elimination, you should find foods to which you are sensitive and remove them from your diet. She points out that for some people eating more raw fruits and vegetables helps, for others eating cooked vegetables helps. For some people, eating yogurt is beneficial because of the probiotics it contains, for others avoiding dairy is key.
In practice, identifying foods to eliminate can be very difficult because people are often sensitive to more than one thing. I had a patient who had eliminated everything in her diet except three foods but was still suffering with debilitating IBS symptoms. I did a Qi Balance Constitution Analysis for her and found that all three foods were not right for her body constitution. When she switched to foods that were right for her constitution, not only could she eat many more foods than she imagined, but her symptoms disappeared and she has had no IBS issues whatsoever for over 2 years.
