Nope, a government that aims to prevent fraud produces the healthiest society. See my comments on the FDA/USDA discussion -- it would be best if they advised the public, but did not outright block products/services.
Their advice means precisely zero when your choices are the cheap, processed, unhealthy food you can afford or the more expensive, healthy option that you can't.
The parent commenter is right, the free market optimizes for cheap and addictive because it's what sells and what will continue producing sales for many years. There's absolutely no incentive for companies to produce even cheap healthy food because the addictive qualities are a much more secure bet that your customer will come back to your food in the future.
The incentive is that many people will pay a premium for healthy foods, which is why companies like Whole Foods exist and do quite well. Certainly not all, especially those who would have previously been facing hunger, so the industry will always exist. I agree there. So you can tax it and make it more expensive and inaccessible for poor people, but that does nothing to make producing healthy foods any easier. That's my point.
