Smokers tend to weigh less than non-smokers, and heroin addicts tend to weigh less than everyone. If the only standard here is “lack of obesity”, then those groups would be considered “healthier” than the pleasantly plump.
How does anyone (especially a government) determine that a food is really “healthy”? Spinach is “healthy”, but if you were locked in a room with nothing but spinach, you’d be dead within a month. Pizza is “junk”, but you could eat nothing but pizza every day of your life and live to be 100.
Pizza is actually a fairly nutritious food. It is comprised of items from all the food groups — grains (the crust), fruit (tomatoes are a fruit), vegetables (e.g. onions), dairy and protein (cheese and meat), and fat (olive oil). The herbs used to season pizza are also full of important vitamins and minerals.
Of course, we’re talking real pizza here, the kind made with thin crust and fresh ingredients. Chicago-style deep-dish pizza, stadium slices, and other forms of pseudo-pie are truly junk food.
I don’t know anyone who uses heroin so I can’t speak to that, but I sure as heck know a lot of “pleasantly plump” smokers.
I don’t want the government telling me what is “healthy” food, as you point out they don’t get it right.
BTW, I don’t consider pizza “junk.”
