The reason you cannot stop eating Pringles chips is because Pringles contains ingredients that make them so addicting that you want to eat more and more Pringles.
pringles contain fat, sugar and other addicting ingredients as well as the flavor of them that make them so tasty that you want more and more.
I know that when I open a can of Pringles I can eat one can of pringles in just about 10 minutes because I usually want one after another and cannot leave any flavor of pringles chips sitting for too long.
Even when I buy some Pringles I immediately have to open at least one can of Pringles and eat them while in the car.
It's normal to be addicted to eating Pringles but they can be unhealthy and fattening when eating too many Pringles.
Also Pringles are high in fat and sodium which is not healthy.
