How many times have we not seen it or done it ourselves, or our parents did it with us, that when a child cries, they are offered a candy, a sweet, something sweet to make them stop crying; after an injection with the doctor, the nurse gives you a lollipop, you fall at school and they take you to the office and offer you a sweet. From a young age, we begin to associate "sadness is relieved with something sweet," or with food, and so we continue until adulthood, still using that formula, "I get depressed - I eat," because it is something already learned. We even see it in movies, someone who is sad due to a problem or a breakup, to comfort themselves, takes a gallon of ice cream from the freezer and sits down to cry and eat until it's finished. As we learned this from adults when we were children, we now apply the same formula to our children.
