Sure, I'm in favour of moving subsidies away from these too. Corn is largely used for animal feed (and also unhealthy stuff like HFCS) and the modern diet is much too overloaded on corn, wheat and soy and its making us unhealthy. Wheat or wheat derivatives are also added as a filler to many foods, which, as someone who has family members who have celiac disease, is pretty frustrating. There are plenty of non-animal products that it might make sense to encourage. As I said, I'm not against subsidising animal products, but I suggested reducing it because the UN said we should eat less meat.
