Why do people always want to eat to fill the pain when they are unhappy?

When you are unhappy, everyone has their own healing methods, such as talking, crying, traveling or sleeping ... In short, there are many methods, but a large part of them choose to eat to fill the pain. Eating, eating goods is the favorite. For a foodie, healing with food is his first choice, after all, there is this foundation. Anyway, as long as you see food, eating food will naturally be impossible. Eat when you are happy, and eat more when you are unhappy. Therefore, it can be said that among unhappy people, it is "nature" for these foodies to fill their pain with food. However, there are still a group of people who are not foodies, and their diet is normal at ordinary times. Even some people who have dieting habits will eat a big meal when they are unhappy. Why is this?

actually, I remember seeing this question there. It seems that there is a saying that food stimulates people's taste buds, fills people's stomachs, thinks about food in their heads, and eats in their stomachs, and their sadness is squeezed to nowhere. Maybe that's the same reason. I have a friend around me, and her solution to sadness is to eat. That time she was lovelorn, so she called me at night and asked me to accompany her to have supper. Knowing her temper, I hurried over. There were two plates of crayfish, a fish, an eggplant and a large plate of leeks in front of her ... I only saw her stuffing her mouth. I didn't comfort her, because the more comforting she is, the more counterproductive she is. Sit down and eat with her. At about ten o'clock in the evening, we swept away everything. When eating, she seems to have never experienced lovelorn. A string of mutton skewers in one hand, and even called "Mmm, it smells good, much more delicious than the one in front of my house". It seems that eating made her forget the lovelorn. On the way home, she said to me: food is so satisfying that men are not as good as food. So there's still this truth?
