Most of the time when people try to define healthy food vs. junk food in a fair and unbiased way, the line gets drawn at "whole foods" vs "processed foods".
A typical burger meal is definitely processed food because the meat is processed mechanically and mixed from different sources (usually with added fat); the bun is made from refined flour and refined oils; and the fries are thinly-cut potatoes blanched and fried in more refined oils. (Not to mention a whole bunch of chemical additives which are the norm rather than the exception; and "hyperpalatability" tweaks which means the food is formulated to taste unnaturally good.)
You could perhaps argue that a home-made burger meal made using whole cuts of meat, a lean wholemeal bread dough, and potatoes roasted in animal fat could count as a healthy/whole food meal, but it would taste different to the typical hamburger meal we all associate with fast food.
Fast food also has an enormous marketing industry behind it which pushes it in unhealthy volume, with maximum convenience, and at (until recently, at least) affordable prices.
Why does grinding the meat at home make a huge difference vs grinding it in a factory? Depending on the cut you choose, the condiments you add, and the portion size, a hamburger at home could be Lot less healthy than a McDonald’s burger. McDonald’s patties don’t have any fillers afaict.
The point is that “junk food” is a pretty amorphous and vague category. If you want to enforce portion or calorie restrictions you can do that, but it would have to be way more encompassing of a regulation than targeting “junk food”
The additives to the meat. Has to retain its color, be preserved, and they also add pink slime to it. McDonald’s adds soy, I believe, and there are all kinds of other things that go into it. If you grind your meat at home you’re going to get some delicious burger.
Heh, grind your meat
