For example, vegetables are generally healthier than meat because they contain more nutrients, less fats e.t.c. Why do certain food categories have properties that make them healthier than others?

Calling foods healthy or unhealthy isn’t a particularly good way to look at them.
There are a bunch of things you need, nearly all of which you can have too much of.
Calories for example; to little or too much is bad. Both directions will literally kill you if taken to extremes.
So in the midst of an obesity epidemic, high calorie density foods are a problem. But in a famine they’re a lifesaver.
In the correct amounts, every food is healthy. Except trans fats and alcohol. And there some things added to food; preservatives, combustion products, etc that aren’t good.
“Unhealthy” is foods that have too much of what people in our society get too much of, and “healthy” is foods that contain more of what we don’t get enough of.
