On the topic "What one do you think is more of a major trigger to IBS?"the key word is "trigger"...a "trigger" is an event be it emotional or tangible, like a food or additive, which will provoke symptoms rapidly. Nomencalture is very important in this area as there is variance and so the specific words used need to be defined to avoid confusing one physiologic event for another, or thinking one is synonymous with another when it is not.So, using that specific and correct definition of "triggers", broccoli is occassionally a trigger food based on statistical probability.In the case of the chronically upregulated gut of the diarrheic-subclasses, either one, stress from worry or some other source, or broccoli can be a "trigger"...some thing which elicits rapid onset of symptoms.But these two facts don't reveal much about the physiology of the underlying problems with IBS, especially diarrheics, as 'triggers' often do not lie at the root of the physiology of IBS as it is now better understood in total.The upregulated gut, for example, is often in this state as a consequence of the chronic release of proinflammatory and proalgesic mediators both in the upper and lower gut within the mucosa and the lamina propria, even at the root ganglia of sensory and motro nerves, as well as mediators which are relased into the plasma and effect the entire body systemically including the structures of the Brain Gut Axis and the HPA axis as an example.This is why people experience "triggers"...which may have nothing at all to do with the underlying upregulation rather simply amplify or provoke it.rarely a food allergy is involved...maybe 8%...and this to can appear to be a 'trigger' due to nthe low dose and rapid onset. Broccoli is also rarely implicated.The normal stress responses of the B-G axis and the gut tissue itself autonomously are merely amplified by and underlying process.IF you can isolate what is provoking the underlyinf peristent cell mediated inflammtory process, thus causing chronic mediator release, you can avoid it and thus return the condition towards normal homeostasis. This can be done with oligoantigenic diet therapy which is designed to isolate end eliminate the specific foods or additives which provoke chronic cell mediated reactions, thus chronic mediator release, and chronic uprgulation making the entire sor called 'trigger' process even possible. This is why for example some folks can even get symptoms from eating too big a meal, too cold a drink, to fatty a meal, or other such general insukts as spicy foods...etc.If you remove the underlying provocation you elimionate the conditions which kae the secondary or "trigger" events into "trigger events"...so even if "stress or borccoli" were so called "triggers", they will be tolerated again and no longer be triggers.Case in point both certin types of stress events AND eating broccoli would "trigger" symptoms of my sever IBS. However, careful examination of what foods or additives were provoking mediator release revealed that broccoli was not reactive.So, after following my patient specific oligoantigenic diet, stress tolerance increased dramatically and brocolli, while still unpleasign to the palate and still a gassy veggie, can also be tolerated quite well.Several other food that I ate regularly were at fault, due to delayed onset hypersensitivity reactions which wer dose dependent so all the dietary logging in thr world never revealed the true underlying foods and additives provoking the mediator release actually responsible for my condition.This is very common.Some examples and discussions can be found here, which will make the true meaning of "STRESS OR BROCCOLI" questions and answers much clearer for the effected sufferers... http://www.ibsgroup.org/ubb/ultimatebb.php...ic;f=1;t=033220 http://www.ibsgroup.org/ubb/ultimatebb.php...ic;f=4;t=000616 http://www.ibsgroup.org/cgi-local/ubbcgi/u...t=035352#000009 http://www.ibsgroup.org/cgi-local/ubbcgi/u...ic&f=5&t=000470 http://www.ibsgroup.org/cgi-local/ubbcgi/u...c&f=10&t=000826 http://www.ibsgroup.org/cgi-local/ubbcgi/u...t=000667#000005 http://www.ibsgroup.org/cgi-local/ubbcgi/u...t=000659#000008 There is also a good scheamtic diagram in nthis article which illustrates the relative dual roles of the CNS and immune response in lost oral trolerance to foods in the generation of IBS symptomology:Alimentary Pharmacology and Therapeutics Vol. 15 Issue 4 Page 439 April 2001 Food Hypersensitivity and Irritable Bowel Syndrome S.
