She bought a happy meal in 2010 and was shocked when she opened it years later

It's no secret that fast food isn't good fuel for your body. But, after seeing how long it takes for a McDonald's meal to decompose, you won't want to eat it ever again!

An experiment

Jennifer Lovdahl's viral post may have revealed something rather gross about one of our favourite fast-food burger chains. The Alaskan chiropractor posted a photo on her Facebook. In it: a McDonald’s Happy Meal from January 2010!

Jennifer's husband spoke to the Huffington Post stating that the pair decided to make the purchase in order to teach their patients at the chiropractic practice about nutrition. But, years after the purchase remained untouched, the young woman opened the box. And to her surprise, all the food remained... perfectly intact. In her post on Facebook, which has since been shared hundreds of thousands of times, she said:

It has been in our office since the day that I bought it and hasn’t gone mouldy, rotten, or decomposed at all. It just smells of the box.

Jennifer's husband told the Huffington Post:

I showed [the Happy Meal] to a junior high class about three years ago. But it's been over a year since I last looked.

Some have doubts

Tons of similar experiments have taken place over time which demonstrates the incredibly slow decomposition rate of McDonald's food. However, this could be due to many reasons such as the amount of preservatives and salt, some even believe that the shape of the nuggets and patties help them to dry out quickly. McDonald’s responded to the post in a statement:

While not knowing the conditions in which the food was kept in this specific claim, what is scientifically known is that decomposition of food happens under certain conditions. Without sufficient moisture–either in the food itself or the environment in which it is held–decomposition is unlikely. This is not unique to McDonald’s food. Any food–whether homemade, store-bought or from a restaurant—can dehydrate in a dry environment, therefore not decompose.

Makes you want to go pick up a box of McNuggets, doesn't it?
