Sure but I don't think current subsidy structure is all that great.

It makes food cheap to everything. Not every person, everything. Including corporations making "bad" foods

It also subsidizes per area of crop, or volume of that crop which means any "sustainable" practices get by percentage less of them per kg.

I think it would be far better if the subsidies were just directly to the people - drop food tax completely (maybe aside "truly unhealthy food") and subsidize the poorest so still everyone can eat, instead of subsidizing essentially John Deeres and fertilizer manufacturers
