if you can eat pasta, you have no trouble with gluten. it's the same wheat based product as bread.
IBS doesn't normally happen after eating two specific kinds of foods.
there are triggers and if you eat them you can have symptoms even 2 or 3 days after too, when they reach a specific type of the colon.
Do you suffer from IBS? Here below you find a definition and it's important for your doctor to rule out other conditions before diagnosing you with IBS. IBS is a functional disorder. This means that there is nothing physically wrong but for whatever reason your gut responds to digestive stimuli more acutely than a normal person's digestive tract does. This results in constipation or diarrhoea or both, and bloating/gas and spasms/pain.)
Through dietary changes (be prepared for certain, perhaps many restrictions) you can lead a normal life with regular bowel movements and without pain. I as a fellow sufferer certainly do now, without ever looking back.
You may very well also have problems with FODMAPs so please see this first:
And the four main digestive stimulants (which our bowels are sensitive to) and we have to be careful about
1. No alcohol or only in small amounts and not on an empty stomach.
2. No caffeine.
3. Fat limited. Calories coming from fat should only be around a maximum of 25% of calories within any one meal. 1g of fat has 9kcal, 1g of carb/protein has 4kcal. A meal containing 400kcal should only have 100kcal coming from fat, 100/9=11g fat. Just how much fat you may be able to tolerate depends on the individual.
4. Cut out wholegrains and limit your insoluble fibre intake. Always eat more soluble fibre within a meal than insoluble fibre. You may have to limit overall insoluble fibre intake within a meal too.
A rough guide to help determine the soluble and insoluble contents of foods: http://huhs.harvard.edu/assets/File/...tion_Fiber.pdf
(the available soluble fibre content of a fruit/vegetable is greatly increased by cooking. almost always the seeds/peel/roughage in a fruit or vegetable is the insoluble part).
Something called resistant starch also acts as soluble fibre.
You would perhaps like to supplement meals with a soluble fibre supplement: I use Benefiber (containing nothing but wheat dextrin here in Britain)
(To dispel the myth that wholegrains get things going for those suffering from IBS constipation:
That is for IBS, if you have it. I'm an expert I have it, and can lead a normal life as long as I eat according to the rules.
