For sure. But one of the biggest effects will be on the development and sale of fake meat - which is worse than even no meat. It is very highly processed and so lots of value added (i.e., $$$) to Big Carb - and they will certainly push back, and push back very hard. Going to an interesting ride.
Old-School Butchers may come back into demand as people will scrutinize the quality of the meat they buy, instead of trusting the Grocery Stores.
