The broadest factor is US food politics. And that's far easier to fix than trying to cure cancer - end market manipulation that keep the costs of some goods artificially high and the others artificially low. Somehow instead we've created a food economy where the absolute worst food for you, even though it's not very economical to grow, is far cheaper because of the disincentive to produce things like cheese and non-bovine livestock and the incentive to grow corn.
