If you have a hard time saying no to a slice of Pizza you are not alone.

Yes there is a reason it takes every last bit of willpower not to eat that fifth slice of pizza. SO hard not to eat it, right? Which is why I just usually go for it.

A new study out of the University of Michigan figured out which foods are the most and least addictive.

Here's what they came up with:

The ten most addictive foods are:

Pizza
Chocolate
Chips
Cookies
Ice cream
French fries
Cheeseburgers
Soda
Cake
Cheese

Here are the ten least addictive:

Cucumbers
Carrots
Beans
Apples
Brown rice
Broccoli
Bananas
Salmon
Corn
Strawberries

The researchers say almost all of the most addictive foods have two things in common: They're processed and they're high in fat.

They say pizza is number one because of a protein in the milk called casein. When the casein breaks down in your system, it can actually trigger the same parts of your brain as drugs.
