According to a new study published in the U.S. National Library of Medicine, we crave food that's addictive. Foods that are processed. Foods with added fat, sugars and salt made the top 10.

A team from the University of Michigan surveyed 120 undergrads and 400 more adults using the Yale Food Addiction Scale to determine which foods, from a list of 35, have them hooked and which they can resist.

Yahoo reports that it’s the processing that seems to be key to addiction:

“In a similar manner that drugs are processed to increase their addictive potential, this study provides insight that highly processed foods may be intentionally manufactured to be particularly rewarding through the addition of fat and refined carbohydrates, like white flour and sugar.”

Here are the top 20 on the list.

1. Pizza

2. Chocolate

3. Chips

4. Cookie

5. Ice Cream

6. French Fries

7. Cheeseburger

8. Non-Diet Soda
