It's a known fact that those fast food or fringe food are bad for us; however, many people still buy from them. Look at McDonald. It is even a worldwide food chain organization. Who doesn't know about that big golden arch. To compete with McDonald, different type of fast food restaurants open their store right by them. Before we know it, it's a whole street of fast food restaurant.
We are living in food deserts today.
Generally, food desert appeals where the low-income urban neighborhoods are and where supermarkets are rare, understocked and overpriced. As other articles have pointed out, the main reason contributed to that fashion is because of people's inability of spending excessive money, time of travlling, no vehicle for going to grocery, and inability of getting around (elderlies and disabled people). However, to take a step further, perhaps we have allowed the situation to happen? People may mentally realize they need healthy food but actually emotionally choose junk food simply because it taste good. "I mean... It's 'healthy food'", people may think and don't want to be bothered with it.
It's interesting to think about.
