Also, salt. I cooked lunch + dinner for myself for like a month, and now all processed food is just too damned salty.

There was an international agreement to cut salt in processed foods by a few percent a year for a few decades, and all stakeholders emphatically agreed to do it, since there's no real downside.

Of course, nothing happened after that.

The problem is that increasing salt a few percent gives processed food manufacturers a marginal advantage over their competitors since by desensitizes them to salt, and also tastes slightly better in side-by-side comparisons. This leads to a prisoner's dilemma type situation everyone is incentivized to work against their own long term best interests.

Regulation could trivially fix the problem by stopping the arms race, and doing it slowly wouldn't lead to people noticing the reduction.
