Are you part of the "cheese team"? To the point of ordering only pasta blue, to eat more than 40 raclettes each winter and change regularly your desserts in the restaurant against a plate of cheese? Do not worry, your love cheese is nothing strange: according to an American study of the University of Michigan, there is a real addiction to cheese, almost stronger than some drugs.

The study, published in the US National Library of Medicine , looked at the dependence of 500 students on certain foods, to complete the scale of food dependency established by Yale researchers who calculates food addiction. If the pizza arrives without much surprise in first place, the explanation is more surprising: it is because it is covered with cheese that many people crack for pizza.

Indeed, the cheese has a highly addictive character according to the researchers, because of an ingredient called casein, a protein found in all dairy products. During digestion, casein releases opiates called casomorphins that make you completely addicted!
