>>213749496Corn syrup and sugar in literally everything thanks to lax food regulations+greedy giant corpos who suffer no consequences (partially due to low social cohesion) +lack of decentralised local agriculture and weird settlement patterns over much of the country after the east coast meaning theres little choice.
