Thank you so much! It really helps to hear this. Why do you avoid pears? You eat apples and peaches and everything? That is awesome! If you have time, could you post a daily sample diet you follow for your IBS. If that's too time consuming, I completely understand!

Have you done the hypno tapes? How about exercise every day. I know it is more than the food. I tend to forget that!

I avoid the fruits that I have found are triggers for me. Too many grapes, too much melon and sometimes pears lead to yuckiness. My husband gets gassy from pears. I eat them, peeled, just not a lot at one time.
Here is my diet this time of year on a workday
2 oatmeal with stevia (one a flavored packet) and smart balance - now I am starting to do a soy fruit and protein smoothie for breakfast
acacia in 24 oz water throughout morning
luna bar
banana then grapefruit
maybe some other tidbit like a cereal bar or almonds
lunch: maybe tofu noodles, veggies and sauce, or a healthy choice mixer (spaghetti one) or a frozen meal like Amy's, or a boca burger, maybe a sweet potato, or leftovers
banana, orange
24oz acacia and water for afternoon
dinner: there are so many different options here, we eat a lot of fish, jasmine rice and broccoli; tofu or shrimp stirfry, homemade pizza or calzone with soy cheese, chicken once a week; I just eat some protein made somewhat lean but not FF, rice, pasta, bread or potato but try to keep that small due to weight, and lots of veggies
dessert: a bowl of cereal and rice milk or homemade soy banana/PB ice cream
I only make fen/pep tea when I don't feel well.

IBS-A for 20 years with terrible bloating and gas. On the diet since April 2004. Remember this from Heather's information pages:
"You absolutely must eat insoluble fiber foods, and as much as safely possible, but within the IBS dietary guidelines. Treat insoluble fiber foods with suitable caution, and you'll be able to enjoy a wide variety of them, in very healthy quantities, without problem." Please eat IF foods!

"IBS-A is a distinct subtype from IBS-C and IBS-D there is no reason to expect that the mechanism underlying the three different subtypes need to be related."
Hold on a second though, there is very strong evidence they are relateed to a problem with serotonin or at least it is involved in causing the c/d or A and motility problems as well as the signals to the brain.
I don't think its likely fructose will end up being a cause of IBS, just like at first they thought lactose was, but now they know it isn't, but having commorbid issues are important.
Increasingly our understanding of IBS is that it is a heterogeneous disorder – that is, multiple factors contribute to the well defined symptoms of the disorder. One of these suspected underlying dysfunctions involves serotonin, which is a neurotransmitter or messenger to nerves. Most serotonin in the body is in cells that line the gut where it senses what is going on and through receptors signals nerves that stimulate a response. The serotonin must then be reabsorbed (a process called re-uptake) into cells. This process appears to be disrupted in people with IBS.
Serotonin and SERT
How does serotonin affect gut function? An interview with Gary M. Mawe, PhD, Professor of Anatomy and Neurobiology, University of Vermont, Burlington, VT. Dr. Mawe is a basic scientist.

I think in some studies they have issues with testing at first and complexities of the issues, for example.

I believe they are related only through the brain-gut misconnection but the precise mechanisms need not be related. For example, methane gas produced by methogans in the colon is physiologically active and known to modulate GI motility in IBS-C. The higher the concentration of methane the more C (see references below). A similar thing does not occur in IBS-D or IBS-A. How methane might modulate serotonin or other neurotransmitters and hormones is unknown. So while IBS-D and IBS-C are related via the brain-gut misconnection they are unrelated via the physiological effects of methane on GI motility.
I don't believe I ever said fructose is the cause of IBS. It certainly isn't. Similarly caffeine, alcohol, fat, etc are not causes of IBS. The byproducts of fructose/fructans and other short chained carbohydrate (lactose, sorbitol, etc) fermentation in the colon are GI irritants and motility modulators like other GI irritants. Excess fructose is an IBS trigger. Since anywhere from 1/3 to 1/2 of IBSers exhibit fructose malabsorption then just like it makes sense to eliminate or reduce dairy, fat, etc it makes good sense to eliminate or reduce fructose/fructan consumption. And it make sense to include it on the EFI IBS trigger lists.

I got ya Syl, just the last post on the d/c and a IBS connection made it sound slightly like fructose was the reason. Even normal people who eat to much can have d.
just fyi
Just some compilations on serotonin and ibs.

Thanks for the links. I will definitely read them.
One thing that puzzled me for awhile was how fructose might play a role in C given that in high quantities it is known to be an osmotic laxative producing D. Now we know methane gas in the colon increases C for those with IBS-C and fructose can be fermented by methogens to produce methane. It is quite possible that excess fructose that passes to the colon in IBS-Cers with fructose malabsorption might be fermented by methogens increasing C. Just speculation on my part
Have a great weekend.

Ah - yea - that is the group that thinks they might be able to develop an enzyme that can be ingested with fructose just like lactase can be with milk. That would be wonderful if they can do it.
