I don't know, I wouldn't say the downsides of the old ways were that the food was non-local, low quality, or unhealthy. A lot of the food regulations were necessary because when you try to do things on a large scale you run into quality and health problems. The downsides are more like people ate way less meat because it was too expensive, there was much less international variety, and there were a lot more farmers, like 25x more. It's really hard to be a farmer. That said, I think the typical person nowadays can afford to eat much better than your typical peasant in the past, at a lower total percentage of income. It's just that because there's so much to spend money on in life now, today's typical peasant chooses not to eat better and ends up romanticizing the past.
