Studies have shown that sweetness is the first taste that humans come into contact with after birth. Babies eat breast milk first after birth. Breast milk is sweet, so loving sweets is an instinctive reaction. And people who often eat sweets will be more and more enthusiastic about sweets, and the more they eat, the more they love to eat.
2. Dopamine neurons are activated.
When people eat sweets, dopamine neurons in the brain will be activated, and then it will release a chemical called opioid, which is similar to morphine. When the brain feels the excitement brought by this substance, it will have more desires for it, so people will want to eat it again after eating sweets.

Extended data:
Sweet food has a long history in China. According to "Poetry Wandering in July", "The second day, breaking the ice, the third day, closed in Lingyin." It shows that in the Shang Dynasty as far back as 3000 years ago, people stored ice cubes in the dead of winter for summer use.
There are many kinds of sweets in China's food, and the exquisite eating method is probably one of the best in the world. Foreigners usually make sweets with cakes such as cloth spots or cream eggs, but every place in China has different characteristics. Besides candy cakes, there are all kinds of sweet soups. Guangfu people call it "sugar water"; Outsiders collectively call it "dessert"; Chaozhou people call it "sweet soup".
The existence of sweets is always a temptation for us. The World Health Organization (WHO) investigated the causes of death in 23 countries, and concluded that sugar addiction is more harmful than smoking. Long-term consumption of food with high sugar content will obviously shorten people's life span, and put forward the slogan of "giving up sugar". China people's consumption of sugar remains high, and the harm of eating sugar has not been recognized by more people.
Eating too much polysaccharide can lead to fractures.
The purity of refined sugar is very high, which can reach more than 99%, that is to say, it contains almost no other nutrients and only a lot of energy. If you eat too much sweets, you will feel full, because too much energy will affect the intake of other foods rich in protein, vitamins, minerals and dietary fiber. In the long run, it will lead to diseases such as nutritional deficiency, developmental disorder and obesity.
On the other hand, the metabolism of sugar in the body needs to consume a variety of vitamins and minerals. Therefore, eating sugar often will cause nutritional problems such as vitamin deficiency, calcium deficiency and potassium deficiency. Japanese nutritionists believe that children eating too much sweets is an important reason for the increase in fracture rate; American nutritionists also pointed out that children who love sweets have a higher fracture rate.
Nutrition survey also found that although eating sugar may not directly lead to diabetes, long-term consumption of sweets will lead to excessive insulin secretion, disorder of carbohydrate and fat metabolism, resulting in imbalance of human internal environment, which will further promote the occurrence of various chronic diseases, such as cardiovascular and cerebrovascular diseases, diabetes, obesity, senile cataracts, dental caries, myopia, rickets and so on. Eating more sweets will also make human blood tend to be acidic, which is not conducive to blood circulation and weakens the defense function of the immune system.
