The concept of meat alternatives is interesting, but there are of course some possible issues. First, with soy: the jury is still on the effects on men. Maybe it's fine, maybe it's not. Until the full effects are known, I'm not comfortable risking growing breasts. It might not even effect most people, but if it does for some, I want to make sure I'm not one.[0] Also, it's possible that some chemicals in it cause cancer.[1] Though with that said, I've started to wonder if everything causes cancer in one way or another. Second, we don't know if some people are better/worse equipped to process soy. I'd analogize this to japanese having special gut bacteria to process sushi and seaweed.[2][3] Maybe those races which have eaten more can process better? Who knows. Maybe it could cause injuries to liver or kidney in people not as well equipped to process it? Large quantities of many things can do this.[4] Again, if we want to tell everyone to replace meat, further research is undoubtedly necessary. Lastly, thinking you ate something can make your body do certain things it normally does, even if you didn't. This is called the cephalic response.[5] If you've ever heard that looking at pictures of dessert can raise your blood sugar, this is the explanation. This is down to total guesswork, but who knows what could happen? Cephalic response means more hcl is secreted. Let's say we're calibrated to release 10 arbitrary units for meat, but 4 for veggie (meat takes more to break down). So you smell and taste meat, and release 10 units. But you eat veggie, so where does the rest go? What if it contributed to an ulcer or heartburn? And could this extend to the delicate balance of enzymes in the rest of the body? Sustainability is a laudable goal, but we shouldn't try to radically alter people's diets without being really, really sure that we're correct. I view anything less as irresponsible. Go back to when people thought fat was evil and sugar was fine, and so people got fat and diabetic. Let's all try to be more responsible this time.
