- Ban some of the ingredients like they did for trans fat
- Force better labeling, like the Nutri-Score in France and EU
- Tax the more unhealthy choices so they don't become the cheapest solution - and maybe use that tax money to subsidize healthier alternatives
This site looks like they're just shaming the consumers for falling for the tricks the government allows the food industry to pull off.
I remember a European MEP who was fighting the food industry to impose Nutri-Score saying on TV that no constituent comes to them saying "help me, I'm too fat". However many expect politicians to boost the job market. The food industry knows that, so each time you try to impose some regulation they'll say "if you do that, we're be forced to do so many layoffs!"
