Indeed yes, soy can cause bloating and gas. We have long discussed that and it is no secret. I avoid drinking soy milk and certain soy products lead to a full, gassy feeling. However, soy products do not cause the health problems some people out there claim. My IBS has not gotten worse the more soy I add. Transferring to vegetarian, I have increased my soy intake without increasing bloating or gas. My bloating and gas almost disappear in summer. My diet is similar but probably less cals in summer. Therefore I conclude that non-diet reasons are partly to mostly to blame for my bloating.
This thread was not started to talk about whether soy is safe for IBS but from a claim that milk is soothing and not a trigger. Not eating milk and eating soy are not necessarily related. One can cut out milk but not include soy. To put it another way, when you cut out milk you don't have to add in soy. So don't listen to anyone who tells you soy is bad so you better drink dairy instead. That makes no sense.
-------------------- 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!
