> The problem is to some people sugar is also more addictive than alcohol or their favorite recreational drug.

That's not a sugar problem, that's a consumption problem. It's also a necessary nutrient to function, so it's addictive somewhat by definition, like water is addictive, or oxygen is.

This is taking the argument to extreme limits, you have to admit? I'm aware of no widespread instances of people self-reporting craving more oxygen than they need to function. There's probably a reason why there isn't an equally prevalent term like "sweet tooth" for many of the other daily required nutrients. It's probably because there aren't that many nutrients that illict an addiction that causes excessive consumption of said nutrient in a single day.

So is classifying foods as "unhealthy" or "healthy" but people do that all the time.
