A lot of people simply don't know how to shop or cook. I used to be a big sister with Big Brothers Big Sisters in a super poor neighborhood in Philadelphia. We'd often go meet our littles during lunch so we could hang out at recess, meaning sometimes we'd bring lunches with us and eat with the kids.

Coming from a wealthy background, I was stunned at how many of these kids didn't even recognize a lot of the foods we brought with us. Quite a few of them had never seen plums or raspberries before and virtually none of them had ever heard of an avocado (not a lot of Latinos in this particular neighborhood). Growing up eating mostly fast foods, public school lunches, and things you can buy at a corner store had only exposed them to really basic fruits and vegetables like baby carrots, apples, oranges and bananas. School lunch fruits and vegetables are usually either underripe or horribly flavorless too, so if that's your main exposure to produce you're not going to end up liking it.

People love to point out that cooking healthy foods is cheaper than buying fast foods and while that's certainly true I think many people just aren't aware of how a lot of people in the US live. People need access to fresh foods but they also need to be exposed to them from a young age and taught to cook them properly - soooo many kids aren't going to learn this when their parents don't even know it themselves.
