No it is a personal preference , just like in China not everyone likes tofu.

I can't say that I never eat fast food because, living in America, it is inevitable. But I do not prefer it because I like to stay fit and it doesn't taste great.

Not every single one, of course. But it is very popular. It's especially popular with lower-income people because it's cheap and there are a lot of fast food restaurants in poorer neighborhoods, where there are fewer grocery stores. Still, I know some wealthy people who eat fast food too and feed it to their children. More than income level I think education level has a lot to do with who eats fast food and who doesn't. I avoid it like plague. Even if I'm really hungry and in a hurry, I won't eat it. It's unhealthy, it tastes horribly (usually too salty / fatty), and somebody is making a lot of money off of other people's bad health and damage to the environment. Here are some nice vocabulary words that I would use for fast food and fast food companies: despicable insidious deleterious detrimental : )

Sometimes we really need fast food.If I am waiting for my flight in the airport but nothing good to eat.So I would choose fast food.Actually I can't tell what is fast food or what is real food.Many food is becoming fast food in these days.Maybe the world is not that serene anymore?
