Veg*n Sick after eating veggie burger

Hmm. That is odd. Have you gotten sick from any other soy products? I've never gotten sick from any soy based products. Perhaps it was a fluke, or maybe you are allergic/intolerant.

My first assumption would be that it was coincidence; if you have the same brand of veggie burgers several times and the same thing happens, then I might think it was an intolerance/allergy.

I've noticed that if I haven't eaten a lot of soy products in a while, then eat a lot of them all in one day, my stomach will be rumbly, and it can make me gassy. Soy is a bean, so if beans affect you a lot, soy products mught too. I noticed it the other day when I ate a lot of soy yogurt, soy cheese, soy milk, and soy ice cream. Actually, come to think of it, it might just be the soy yogurt, because tofu doesn't seem to have the same effect. Anyway, it could just be the way a certain brand is processed, maybe a different brand would be better. It is also possible to find veggie patties that aren't soy based - I know President's Choice makes one available in Canada, but I don't know about in the US.
