suddenly we are living in a society where 'junk food' is banned and ideally everyone is a vegan.
Vegans have a high incidence of disease, particularly heart disease. TBH, the whole anti-fat things is contraversial. Health science is often nebulous at best. Recent evidence suggest a completely different "smoking gun" for heart disease, and that prior assumptions are wrong.
IMO the only "unhealthy food" that isn't all that up for scientific or logical questioning is large amounts of refined sucrose (table sugar). But TBH, before we went down any track of regulating "unhealthy food", the public should demand a 100% "smoking gun" on it. I doubt that will even manifest with fat, if anything I think the opposite is already true, its already being disproven. Give it some time, i reckon that house of cards will have fallen.
Sugar, well we have some good direct evidence, but not enough to call it a smoking gun.
So, yeah, anyone that introduces regulation on "unhealthy food" should be seriously questioned, and the general public should not be so gullible as to buy into mere statistical associations.
That said, I think, addiction wise, if one was to entirely forgo _sugar_, that it would be harder than forgoing nicotine, and comparable/close but not quite as hard as smoking. Theres proven evidence sugar is addictive, and ive tried cutting it out. It is damned hard - serial, id compare eliminating all sugar to cutting out smoking (the same sugar which we ironically feed to children when they have no defense against physical addiction)
I doubt the same is true of fat. We might enjoy it, but its nothing like as hard to surrender as sugar.
So, actually "junk food" is not a bad counter example. High refined sugar are highly addictive, seem by the science to cause a large amount of disease and we not only recommend it, but we offer it to young children. That kind of puts the whole, less addictive and probably less harmful nicotine into perspective, lol (not that we should offer that to adults or children either).
Cultural bias and moral panic, is an interesting phenomena.
