Why do we find dessert and eat it when we feel like our stomachs are about to explode? [사진=게티이미지뱅크]“Second is a donut?” There are people who go looking for sweet desserts, saying that there is a separate ‘dessert stomach’ even after eating a full meal. Why do we find dessert and eat it when we feel like our stomachs are about to explode?
This is because of ‘sensory-specific satiety’. When you keep eating certain foods, you get bored and lose interest, but you find new foods attractive. When you eat a variety of new foods, your stomach is overcome and you feel interested again.
LiveScience, an American science media outlet, explained this phenomenon by citing the results of two studies published by Professor Epstein at the University of Buffalo School of Medicine in New York, USA, at the National Center for Biotechnology Information (NCBI).
In the first study, 32 women were given mac and cheese five times a week to one group and once a week over five weeks. They found that women who ate mac and cheese every day ate less than women who ate mac and cheese once a week.
In a study conducted in 2013, 31 children were divided into three groups. For five days, the subjects were divided into groups that received the same brand of mac and cheese, a group that received multiple brands of mac and cheese, and a group that received a variety of high-calorie foods, including chicken nuggets and cheeseburgers. The results of the study showed that children who received a variety of foods ate significantly more food than those who received only mac and cheese.
The food intake patterns shown in the two studies can explain both the tendency to eat a sweet dessert after eating salty food or to overeat at a buffet with a variety of dishes. “When new foods are continuously offered, people tend to keep eating until they can eat no more,” Epstein said.
According to the researchers, once a sweet dessert is consumed, the brain secretes dopamine, a chemical that makes us feel rewarded and happy. If you always eat dessert, the release of dopamine changes from after eating to anticipation of other foods. In this way, a craving for dessert is formed, and the possibility of eating a piece of pie or donut increases even after eating all the rice.
Some experts explain that the desire for variety in the diet is also an evolutionary response acquired to obtain essential nutrients that our body needs, such as vitamins and proteins. The problem is that this diet can ruin your health. It is helpful to redefine the dessert routine by utilizing the sense of satiety for each sense. Having sweet, healthy snacks around you, like fruits and nuts, is a way to enjoy your diet in a healthier way while maintaining variety.
Rawls, director of the Institute of Human Eating and Behavior at Pennsylvania State University, USA, advised that it is good to have a variety of low-calorie and nutrient-rich diets to meet the need for variety in the diet while preventing overeating and obesity.
