With food the issue is how our body is tricked to not feel full when in fact through more sugar and fat he got way too much calories. Then getting addiced to sugar and fat. While of course very problematic, that's a different matter, not directly comparable.

In general though, by nature's design, people start to consume everything unknown slow and increase the amount/dosage. That is how we function.

The fact some people do not know moderation, for various reasons, is not a sound argument for prohibition. Some will always abuse anything.

You can die of drinking too much water, and certainly people did in the past. Can you prevent that from happening, by controlling the access to water somehow? No.

In my opinion the more nonsensical idea is to try to forcefully protect people from doing harm to themselfes, when common sense and normal behavior will do on its own. There is free will and autonomy over the own body. That's the limit of regulation.

The better aproach is education in a honest, factual way.
