Will that achieve anything?

People know the effects, people see the effects, people don’t care.

Just seems like a silly outdated idea. Isn’t it well established that the best way to stop people from buying stuff like this is plain white packaging and advertising restrictions?

Will that achieve anything?

Yes! Various countries implement a “traffic light” style health meter that is legally required to be on the front of packaging that also gives a little subtext to say what causes it to be yellow or red (least healthy). So it will say stuff like “excess sodium” or “too much sugar” which actually does work. People don’t even realize that some staples are considered UPFs because of preservatives (Tortillas), or are otherwise unhealthy (too much sugar and preservatives in ‘health’ cereals and yogurts).

This allows people to find staples that do not contain shocking amounts of sugar, preservatives, or highly processed options within the same category. It’s worked when implemented well :)

In the case of tortillas I imagine the label would do more harm than good. Because what are people going to do, stop buying tortillas? They’d just learn to disregard the label. The only way I could imagine it working is if some tortillas had the label and others were safe, then you could buy the safe ones.

On the other hand, why not just ban the dangerous preservatives and let them all be safe?

Unless we are saying that it’s ok for poor people to eat dangerous food if they can’t afford the good kind
