WHO INVENTED A HAMBURGER

Hamburger was found by american people.
Ingredients for hamburger are:
-grounded beef
-onion
-leaves of lettuce
-dressing
-you can add something on your own too
And you need to put all of that ingredients in round bun. Hamburger is important because it's good and cheap but it's unhealthy fast food so people are  fat because of that. My advice for that is to STOP EATING THAT UNHEALTHY FOOD. I personally don't like fast food because i'm afraid of being fat as those who eat that. You just need to listen to me and STOP going to Mcdonald's. Hamburgers could be healthy if we'll make fruit ones or hamburgers without much callories. Even if we'll eat them we will need to burn the callories with exercising, if not maybe one day hamburgers will be eating us.
