Where are you getting price controls? The "answer" is a bunch of stuff that tbh will impact prices. For example, ending corn subsidies would make food more expensive on average, but you personally would save money because the healthy choices you make would have better economies of scale.
It's not like everyone in the world has this problem. It's concentrated on the USA; the food here is less healthy. I don't know you or what strengths or weakness you have, but everyone responds to incentives.
