It's the yeast. Perhaps you could filter. At least make sure you aren't drawing loads of it from the bottom of your keg.

My grandpa used to eat a teaspoon of yeast every morning. Helps with regularity. Too much of course can make you really really regular, to the point (loosely speaking) of irregular.

Nice.

I brewed one beer, a sweet(ish) stout (no lactose added, just high FG), that just rocked my GI tract every time I drank it. I could handle one pint, max. SWMBO experienced no ill effects, so she ended up drinking most of the keg.

At first I chalked it up to the yeast, S04. I convinced myself that my S04 brews had done the same thing to me in the past. But when I brewed later batches with S04, I imbibed without trouble.

So I thought it might be the roasted grains, but ditched that idea when I realized I had been drinking very dark beers for 15 years with no problems.

All I can come up with is the high FG. I guess my stomach just doesn't dig the excess sugars, which I think was mentioned earlier in this thread. Anyway, if I have a point here, it's that everyone's body is different, so it's hard to put your finger on why you're reacting to a particular brew in a particular way.

Why don't you serve hot dogs, then if they all get sick you've got something else to blame it on.

EDIT: Wait, how old is this damn thread?

My hombrew has made me regular and I am glad. No toilet soup, just appropriate passage.

...everything else I want to say seems like TMi

If the banana is any indication of your constitution, then it definitely is TMI (God I hate that acronym... I feel like a teenage girl using it).

Anyone mention if your buddy might have a little IBS or Celiac Disease? I have met some gluten free brewers who have to make beer because of Celiac. They might have a slight irritation to gluten or yeast.

My vote goes to something they ate as well.
