Pollan touches on this in The Omnivore's Dilemma. The low price of a burger is an illusion because the real costs to the environment and public health are externalized, making fast food artificially cheap due to indirect subsidies on corn byproducts and other animal feed. Healthy food competes on a totally different cost base.
There's also the split between eating with agency and just consuming which requires a top down solution. Unless the government stops subsidizing meat and corn subproducts linked to health issues the majority of people will always gravitate towards the cheapest calories available.
