Why are we subsidizing soy crops anyways? Soy is terrible for your health. It contains loads of phytoestrogen and allergens. We are reliant on exporting the crop because it's not a part of the typical american diet. It's just bad news altogether.
However, I am skeptical of all of the claims about soy particularly if you eat it as only part of your diet.
That said Beyond Meat doesn't contain soy. Impossible does though.
I'm not proposing all production in the US switch to soy crops, and your argument seems pretty disingenuous to me
Impossible Foods is a drop in the bucket compared to tofu, but, there are too many calories of soy grown in the US to feed them all to humans. That's also true for corn.
