There was this art experiment suggesting that McDonald's food doesn't decay, this of course sent people into a panic, asking, exactly what's in that food?
A New York photographer left a McDonald's hamburger Happy Meal, complete with a small side order of french fries, sitting on a shelf in her home for more than 18 weeks.
Every three days, Sally Davies took a photo of the food.
As day 137 rolled around, the food looked pretty much the same.(photo above)
So, the assumption was, McDonald's must be using dangerous preservatives to make the food look fresh.
But scientists argue that preservatives aren't the main reason why McDonald's food doesn't decay -- it's the fat.
Those delicious fries and burgers at McDonald's have a lot of fat and
"Anything that is high in fat will be low in moisture," says Washington State University Professor Barry Swanson.
Low moisture on a surface means mold can't grow, which means the food can't decay.
And then there's the salt.
A McDonald's double cheeseburger contains 1,150 milligrams of sodium, while a large order of fries contains 350 milligrams.
Sodium acts as a preservative, contributing to a low decay rate.
We know there's probably some point with an agenda trying to be made here, but to us, it's not important.
We just want to super size it.
