. After eating several dishes, I found myself so full that I couldn't eat anymore.
I suddenly felt lighter and enjoyed the tasty cake. But wait, why do I always have room for dessert?
What's your favorite food? And would you like to eat it every day? Imagine that you could eat your favorite food for two days in a row. Sounds good, doesn't it? Now, let's have the food for five days, and then ten days. You might get tired or this food.
Dessert is usually the last dish served. After you've eaten many different kinds of foods, you gradually begin to lose interest in them. At this point, a dessert comes in as a different kind of food. The novelty (新颖性) makes your brain want to try it out.
When you eat dessert, your brain gives out dopamine (多巴胺). This chemical will make you want more sweet things. So the dopamine "creates" new space for more dessert.
Of course, because desserts are so delicious, we must be careful not to overeat. Too much of anything can be bad for your health!
