For all the people McDonalds uses the ass part of the cow to feed burgers, and there fries are fried in the oil from the meat.
The oil is a special oil that hardens quickly and is very bad for you.
Which is why America is fat, Im 200 pounds and in Middle school, McDonalds forgeted me over, don't make my mistake.
The only fast food I ever visit is Subway (if considered fast food) and In & Out.In & Out is the healthiest fast food you will ever know. They make their fries on the spot from fresh potatoes. I've seen them making it before.
They have the window in the drive thru where you can see them chop the potatos and such. :D
I love In And Out. :D
