Is this common in people with IBS? Does anyone know if it similar to fructose malabsortion in that a cumulative amount of corn products can cause problems? thanks

What kind of corn products are you having difficulty with? There isn't a corn intolerances similar to fructose malabsorption. However, some corn products can be high in IF.

I dont know for sure if it is the corn or what. But it seems that some products that should be safe to eat for IBS make me sick. Im noticing too much cornmeal (which may be bc of IF right?) But also baking any goods seems to cause some trouble and Im wondering if maybe its the baking powder. I hear that corn intolerances are often misdiagnosed and pretty common.

Cornmeal is a whole grain. Heather says "Oatmeal, brown rice, and corn meal (polenta) tend to be the best-tolerated whole grains for IBS". I cannot eat cornmeal -- too much IF for me.
Baking powder shouldn't give any problems - it is a mixture of baking soda and cream of tartar (a mild acid).
Except for the IF corn per se is not a known IBS trigger. Do you have difficulties with corn starch?

I have been predicting that corn allergies and intolerances (pets have these) would be starting soon. Soy allergies are much more prevalent now due to GMO soy, and corn is almost all GMO now plus it is in everything due to government subsidies of corn. That is why corn sweeteners have become so common and food with no nutritional value is so cheap. Anyway I haven't heard of corn allergies yet but am just waiting for it!

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!

I totally agree with you on this....I heard high fructose corn syrup has been banned in Europe for years now...it's so sad what has become of our food...

Plus the fact that corn is universally contaminated with mycotoxins. Now THAT can't be good for the body.

Yea, the only thing that has cornmeal that I sometimes eat are breads and it usually is one of the last ingredients. THomas' bagels have cornmeal in them, would you be able to eat those? And im not sure yet about the cornstarch,. I think it may cause me problems. The reason I am wondering about this is becase I had these candies made of cornsyrup (it didnt say HFCS but could it have been?), modified corn starch, and artificial colorings. Not the best choice I know but I've never been so sick in my life. I felt the effects the next day as I would with excess fructans.
Another question, why is it that many foods like bananas dont give me gas when I eat them, but when it comes time to have a bowel movement, it feels like I have so much air and gas. This must be a problem with the large intestine right? Is that common, and would taking beano help eliminate this? It seems that before starting this diet, I would feel most of my pain directly after eating but now my pain is delayed, usually in the mornings when I need to have a bowel mvmt. Anyone else have this?

Corn syrup contains glucose. It is safe. I have not had problems with modified corn starch. It is composed mostly of glucoe. I have had troubles with artificial colors and flavors.
Gas is generated in the colon by colonic bacteria which ferment the soluble fiber and resistant starch in bananas and other foods. It is common. It usually occurs many hours after eating. Beano may help with some foods.

I had testing done that showed I had a corn intolerance. Since I starting avoiding all corn and corn by-products (which is NOT easy, let me tell you!) I have felt much better. This may or may not be your problem - if you can't get tested it certainly wouldn't hurt to try avoiding it and see what happens.

High fructose corn syrup is alive and well throughout Europe but there it is called isoglucose or glucose-fructose syrup like in Canada. Unlike North America, Europe has a production quota. Only high fructose corn syrup from genetically modified corn is banned.

I had some bad gas after some corn chips a few days in a row. These were baked and no fiber. I've noticed a trend with corn based snacks so I'm not ruling it out. My symptoms are gas, bloating, cramping. It usually starts later after 8pm and lasts sometimes until 4 am. I often have IBS-C (not chronic), and sometimes D every few weeks.
I'm trying some elimination diets with wheat/eggs/dairy and will try fructose if all else fails. Can allergy testing help me with this?? Has anyone had success with allergy tests?

I checked with the manufacturer. The product does contain fiber but since they are using a serving size of 32 grams the fiber content is just less than 0.5 grams. The labeling regulations let them say it contains 0 grams per serving. The product contains about 1.5 grams of fiber per 100 grams. The fiber is mostly insoluble fiber.

I've got corn-intolerance (?) too!! 
From eating corn starch I get nausea and diarrea.
I've got fructose malabsorption too (lucky me). I get very bad stomach pain/cramps from it.
I get the same reaction from eating sucrose (table sugar) as from corn.
I see Syl writes that corn starch is just glucose...
So perhaps my problem is (ao) glucose ánd fructose??? 
I cán eat rice syrup, no problem. (and wheat!)
But not: agave syrup (stomach pain), maple syrup (nausea), dextrose (stomach pain), fructose (stomach pain), sucrose (nausea)
Can anyone make any sense out of this??!

Just a bit of background information first and then a comment.
Rice syrup contains 45% maltose, 3% glucose, and 52% maltotriose
Agave syrup contains 56-92% fructose and 8-20% glucose
Maple syrup contains about 97% sucrose (glucose + fructose) and 3% glucose and 1% fructose
Dextrose is 100% glucose
Glucose is the most important source of energy for the human body. Usually problems with glucose are related to blood sugar levels which is indicative of problems like diabetes and hypoglycemia. Diabetes effects the GI tract producing some of the symptoms you mentioned. Have you been checked for diabetes and/or hypoglycemia?

Agave syrup is high in fructose. Maple syrup has a high sugar content per serving. The bacteria likes to feed off of sugar and create the stomach problems. You may want to go without added sugars for a while and eat more plain potatoes/rice/protein,etc until you feel better.
I'm not an expert on this, I'm about to do a diet to check on the same problems. Hope you get better!

Have you been checked for Small Intestine Bacterial Overgrowth? You may have a sensitivity to sugar. It's possible. I have the same problem. Fructose is definetely worse but too much sugar (like more than 10-15 grams Id say) will give me an immediate stomach ache.

Thanx for the info!
That explains the agave and maple syrup.
Apparently sucrose (1:1 fructose-glucose) is too much for me..? But I cán tolerate carrots, which also contains 1:1 gl-fr, I thought.
My bloodsugar has been tested a couple of times, it was just fine (like 5.2-5.5 after a meal or so). Hypoglycemia my doc doesn't really 'believe' in to be a real disease. But my bloodsugar is always around 5 when tested, so I don't think that really is my problem..(?) Also normal when I was sober one time (don't know the exact value anymore, but around 5).
It absolutely seemes to be my stomach/intestines that's giving me symptoms.. (all symptoms started after GI-infection)
But I still don't understand how I cán eat as much rice syrup as I'd like and not dextrose (only tried that once in a larger quantity, but I can eat small quantities of it in processed food).. And no corn starch!?
Maltose/maltotriose will also be converted to glucose by maltase I guess? Just as corn starch, which I cannot tolerate..

I haven't been tested specifically for SIBO I guess...
I did had 'advanced' stool tests done by an naturopath, a doc specialised in intestinal bacteria. She couldn't find anything abnormal.
I'm not sure small intestinal bacteria where tested too, but I think they would have found them too then?
When I get the nausea symptom it starts in about 1-15 minutes after eating something 'wrong' (glucose/corn starch, but also red meat for example). The D starts in about 1-2 days (otherwise C) if I continue eating it.
The gastric pain after fructose starts in about 2 days (after being symptom-free).

I do eat as little as possible sugar/fructose, to avoid problems. I've been on the diet since January, since March I really started to find out what works for me. My symptoms are about 80% reduced now when I stick to the diet (but I still need medication).
But I'm still trying to find out what I cán eat, because my diet is really really restricted right now.
First of all, that's really frustrating to me, but secondly I think it's really unhealthy too (vitamins etc).
Everyting I try seems to give me trouble, but there's still a lot to try I guess. Hopefully I can eventually create a somewhat less restricted and healthier diet...

Yeah I know what you mean, it is frustrating. I'm sort of searching for similar answers as you. You're doing the right thing though with your research. I suppose a vitamin (with out sugar additives) and fiber supplements would be the best way to get some of that extra goodness missing from fruit.

High fructose corn syrup is known as isoglucose or glucose-fructose syrup in Europe and it is not banned. However, it is under a production quota first implemented in 2005. In 2007 and 2011 the quota was increased due to increased demand.

I have a corn allergy. Corn, corn flour, corn syrup, corn starch, etc. And corn actually comes in many, many different forms. A lot of the things that are IBS no-no's are also things that are at their base made from corn (ie MSG). This is a good list of corn derivatives: http://www.cornallergysymptoms.com/corn-derivitives.aspx - Some I can have, some I can't. It depends on how sensitive you are to it.
I, of course, have no idea if you have it but I can't eat hardly any. If I do you'll know within a couple hours because I'm just really angry. This crazy aggression comes over me and suddenly everyone and everything is on my nerves.
Other people get excema, or IBS type symptoms, or a million other things.
If that ever happens to anyone else that reads here: I can take a good size dose of a liquid vitamin B complex and about 20 minutes later I'll be okay. More relaxed, etc. Sometimes it happens to me on accident. It gets pretty frustrating to eat for IBS, Corn Allergy, and Diabetes!
Good luck!
