Turns out there's more than just those 6 people in America.

The American diet is uniquely awful. Your social group is likely to include people in a similar socioeconomic position to you. If that means those people are eating lots of vegetables and clean fats then congratulations, you're doing pretty well.

That does not describe the diet of most Americans. It's rich in refined carbohydrates, "dirty" fats, processed meat, and very few vegetables, and the primary vegetable is the potato,, which is also essentially just another carbohydrate. It's better than deep fried flour, but not by much.

Pizza, all things considered, is fine, practically healthy, compared to the cheeseburger and fries that makes up the typical lunch for many Americans.

Most of the food we have easy, cheap access to is arguably addictive, high carbohydrate, low in nutrient, and generally just bad for you.

Which is why we have an obesity crisis and some of the worst rates of diabetes in the world.
