Due to the enormous amount of sugar and / or fat, our human organism demands more and more food, because junk food doesn't make us full for a long time or at all. Through the addition of the flavoring substances and flavor enhancers, as well as other artificial additives, the consumption of this food can also lead to a limited or pronounced addiction.
