There are some good posts going on right now with food allergies/insensitivities/intolerances, etc. causing some or most of our digestive problems (see Joe and Laney's posts). As an addition to these, I would like to recommend the least complex elimination diet book I've found to date, "The False Fat Diet" by Elson M. Haas, MD.I've been meaning to try it, got busy and forgot about until I_H8_IBS posted his site on a thread 4 or 5 days ago. I didn't realize he had a computer site. Anyway the premise of the book:1) Food intolerances, allergies, etc. contributes to many digestive problems.The most common 7 offenders being: dairy products, wheat, corn, eggs, soy, peanuts and sugar.2) He does an in-depth discussion of the problems and symptoms of eating these foods.3) The best of the book: He offers the simplest 7 day menus (3 main meals and 3 snacks) for a total elimination diet of these 7 offenders. These are simple food found in the grocery stores. There's not alot of new ingredients, hard to find foods, etc. In addition, he outlines a juice elimination diet (which I personally don't recommend), another 7 day of menus for a limited elimination diet, and then a 7 day of menus for mainenance once you've determined your sensitivities.4) Last, he includes the general vitamin supplement recommendations, good list of reactive food families, stress management, and more. I got the paperback for $6.99 at Barnes & Noble. Unfortunately, I haven't tried the diet yet,but for anybody looking for an easy diet plan I strongly recommend it.
