Almost any diet that contains mostly real food rather than artificial food-like substances will produce substantial improvements in health. Contents are hugely secondary to actually consuming real food.
Only because they don't focus on micronutrients.
> where organic food tends to be better because soil health is actually looked at.
You don't think large scale farmers look at soil health? Every single large scale farmer knows about soil health.
Maybe governments should set up production of healthy convenient packaged food and give it away for free. Then gradually ban businesses from selling the worst products.
Besides, I don't advocate for nationalising entire food production. Just carving out small segment that by design operates at a loss because it acts altruistically not with market ruthlesness towards consumers.
It about quality food being vital for everybody, not about importance. A public “default food package“ could have a big impact for many families health. The private options can stay , regulated, as well as for water, electricity and safety.
