If you focus on FODMAPs and take Beano whenever you eat an complex carbohydrate on the CCI list you should have almost all of the carbohydrate intolerance covered

Well now I'm a little confused as I thought we established that polysaccharides (the starch foods like rice, pasta, potatoes) should not be considered in CCI as they are different than oligasaccharides?
I already started looking into glucose polymers (starches) and Amylase. And low and behold, the role of the pancreas comes up again. I don't expect you to know/remember everything about me or that I've posted but I have documented my very puzzling experience with Cholestyramine being the one treatment I've tried over the years that has actually worked. Unfortunately, it was short lived and abandoned by my GI.

Correct.
Starch is digested in two steps. Amylase in the saliva and pancreatic juice breaks the starch into molecules called maltose. Then an enzyme in the lining of the small intestine splits the maltose into glucose molecules that can be absorbed into the blood.
As I recall cholestyramine is a resin belongs known as bile acid sequestrants that binds to bile acids from the gall bladder in the intestine. While, the pancreas and the gall bladder share a common duct they do different things. The pancreas produces digestive enzymes and the gall bladder stores bile produced in the liver. Bile emulsifies fat so pancreatic enzymes can digest it easily. Bile is not an enzyme and it is not involved in carbohydrate metabolism.
Problems with starch digestion is something you would have to talk to a specialist about as this involves problems with other organs not just the intestine.

My last post was a bit rushed and what I was trying to get at was if the foods I'm questioning aren't triggers for CCI (because they are polysaccharides - not oligosaccharides) then Beano would be a waste of time? And in fact, I can probably move on from considering CCI as I already avoid eating foods/carbohydrates that are oligossachrides?
Like I've said before, it's easier for me to list what I do eat rather than what I don't eat which incidentally helps me to rule out other causes but at the same time is frustrating not only because I'm down to such a small diet but when you are eating so few foods, how can it be so hard to find the problem? So, as I mentioned, I looked for the common denominator between the foods in question (rice, potatoes, oatmeal, bananas etc.) which lead to...
Starches produced by all green plants as an energy store. It is the most important carbohydrate in the human diet and is contained in such staple foods as potatoes, wheat, maize (corn), rice, and cassava.
...and...
Amylase... an enzyme that breaks starch down into sugar. Amylase is present in human saliva, where it begins the chemical process of digestion. Foods that contain much starch but little sugar, such as rice and potato, taste slightly sweet as they are chewed because amylase turns some of their starch into sugar in the mouth.
So, of course the next step is to look at Amylase deficiency and it's symptoms. There are plenty like sinus congestion, itchy watery eyes, fatigue, blood sugar imbalance and frequent headaches but nothing relating to IBS like symptoms.

In traditional Chinese medicine, the spleen (includes stomach and pancreas) is the major organ that controls digestion. Digestion, digestive fire transforms and transports food, nutrients into blood. Blood (nutrients) build, thicken, fuel, heat, cleanse, cool and moisten. Weak digestion transforms and transports less, decreasing nutrient absorption, blood, while increasing waste, as whatever food not digested, absorbed becomes waste sent directly to the large intestine for temporary storage and eventual elimination. Long-term low protein, low fat and high carbohydrate diets, in addition to drugs, surgery, chronic disease, etc. weaken the spleen, digestion, blood (deficiency), structure and function.

Allisonmary, thanks for sharing. It is so nice to have an holistic view.

The experts are in the process of figuring out if the carbohydrates which break down to amino acids and to tryptophan and then create serotonin, effect serotonin in the gut and hence symptoms.

I am friends with the doctor who did this study.
This is an email from Him to me about it.
Dr Drossman
"These are reasonable comments, however the study was not a clinical trial, nor is it meant to be a recommendation as much as to understand whether CHO restriction might have clinical benefits in IBS. To uncerstand the role of CHO, fructans, serotonin, etc. requires a larger, methodologically different and more complex study, rather than a case series of a few patients;. This is only preliminary and readers should be cautious about what to conclude from this.

I guess it wouldn't hurt to experiment with such a diet, even though it is preliminary. A benefit is a benefit, especially when IBS symptoms are concerned.

Agreed, Kim. It certainly isn't going to hurt.
