I posted this on the Research/News/Abstracts section at this board site, but realize a lot of you don't always look there, but may be concerned about the possibility of Malabsorption and Carbs. Some of you are at a loss eliminating everything and anything you think might be the culprits when the list might be a little narrower than you might think. Processed/packaged foods/beverages/dressings/sauces may contain these components or other irritants that we are not cognizant of. (Benzoic and Citric acid, plus whey was found to be irritating to my gut in provocative sublingual testing). Therefore, it is best to start this elimination process out without including packaged/processed foods/beverages, and be careful about not adding dairy, fruit, and possible vinegar and tomato to your sauces/salad dressings.I have narrowed both fruit and dairy in my diet as being the greatest offenders and virtually eliminating them has helped tremendously with my bloating and gas. I must say that acid foods like tomatoes and items with vinegar seem to be a problem for me too. This could be because acid foods/beverages/sauces are more irritating to the gut.Dr. Lamar Gibbons has written books, (I reviewed/replied to in the Book section here)which explains more about siting the reasons behind why it might work. I don't know if all his thinking is totally correct on it, but he does proclaim that much the same type of diet is very successful with his patients. He also gives other conditions to consider if this diet doesn't work, such as the possibility of Celiac Disease in which you would have to eliminate wheat/gluten additives. A separate grain elimination could be done. The grain I seem to be sensitive to is Soy.Of course Dr. Gibbons also states that there is the matter of ruling out and treating other conditions for your problems developing, such as gall bladder disease (fats being a problem in that case), and infections from microbes that have been ingested or from some microbes just over-taking the bowels healthy flora as a result of taking some drugs such as antibiotics. In the latter cases of infections, however, he also believes the diet can be helpful.I think it would be great for those who have tried this already and found it has been successful to post about it, and for those who are at a loss as to what dietary changes might help, to consider trying this method of eliminating dairy and fruit items in their diet for a week or two and supplementing with Calcium supplements and buffered Vit. C (both taken with their food). Then they could come back and tell us how it went. Gradually, it can be tested again by adding small amounts back in, one at a time. You may be able to tolerate only small amounts like one fruit/dairy item per day in the end, which seems to be my limit. Let me know if you are willing to try this out because I would be interested in seeing the results.Don't forget the purity of your testing is a factor, and if it doesn't work, think about the other suggestions mentioned (such as treating a possible infection, and trying grain and fat elimination). Of course things to help with your diarrhea like calcium carbonate, and with constipation like fiber, filtered water, magnesium supplements, and heart healthy oils might be useful as well. Much of this is Rome Criteria suggested, but many doctors don't include the diet recommendations when they tell you that you have IBS. You may find in the end if the dietary changes work, you don't need the antispasmodic drugs anymore which doctors are often quicker to prescribe for patients than the diet. Good luck and please report back!M.
