I'm not a vegan or even a vegetarian, but I often aim for having meat- or animal product-free meals. Recently I tried replacing dairy milk for soy milk, but I found out that it doesn't agree with me. Same for soy yogurt in place of dairy yogurt. I end up getting minor stomach cramps, a ton of bloating, and really nasty-smelling gas. Has anyone else ever experienced this?
My understanding is that this is due to certain oligosaccharides found in soy products. I can eat legumes easily (like, I can literally eat a can of black beans without any discomfort), it seems like soy milk, soy yogurt, and Soylent get me badly though. Would Beano be helpful, perhaps? My two major reasons for choosing more vegan/vegetarian options are 1) I feel bad for animals and 2) to be more environmentally-friendly... but I have no way of determining whether the process to make and produce Beano is relatively harmful towards the environment, which makes me question if replacing soy milk and a Beano tablet in place of dairy milk is really a net gain in that regard.
