What's your opinion on fast food say McDonald's

How often do you eat at McDonald's? I go there maybe 3 times per month. Some people say they are stuffed after eating there and don't need anything for the rest of the day. I feel like I could eat more with no problem and I'm not fat. About the health part of discussion I think you can eat anything as long as you eat versatile and what is really healthy these days. Even if you take bio food for example chances are it will grow from polluted ground and same goes for private gardens if you decide to grow your own. I know some kids that were especially cared after for example they weren't aloud to play outside on the ground and ate only certain products and they were even sicker than those that played in the dirt. It's strange everything is basically slowly killing us and yet we can't live without those things. I like Coca Cola despite the wide known fact it desolves teeth and so on. Sometimes worst things are the most desirable don't you agree?
