You know what would be way better than a symbol for "healthy" food would be requiring manufacturers to label food that fails to meet standards as "unhealthy." Bonus points if you tax it to death so it's no longer economically viable to sell garbage and label it "food"
Like, shit, the public perception is that I can't afford healthy food anyway. But at least if the unhealthy food was also labelled it'd be easier to avoid
We're burning the wrong Amazon
