If you put sugar water on a newborn's tongue, he or she will look happy. If you let your newborn lick a bitter-tasting substance, he or she will grimace. This shows that the newborn's response to sugar water is genetically programmed rather than learned. Sweets stimulate the dopamine reward circuit in the brain, making you feel happy. It is difficult to change something that is based on genetics. This desire for sweetness is causing the problem of obesity. The challenge for countries with mature economies is how to reduce obesity.
However, there are ways to make your child less prone to obesity. The idea comes from an experiment in which pregnant mice under germ-free conditions were given a high amount of dietary fiber. Divide the pregnant mice into two groups. One group is fed a diet low in dietary fiber. The other animal was fed a diet high in dietary fiber. Mice offspring from these two groups were fed a high-fat diet. In the intestines of mother mice fed a diet high in dietary fiber, short-chain fatty acids were produced in large amounts. The results showed that mice born to mothers who ate a diet high in dietary fiber were clearly less obese. On the other hand, mice born to mothers who were fed a diet low in dietary fiber became obese as they grew up. It has been found that the mother's intestinal bacteria are involved in the way a child grows and their future body shape. The key to suppressing obesity in mouse offspring was short-chain fatty acids produced by the mother's intestinal bacteria. This suggests that using foods high in dietary fiber can help prevent your child from becoming obese, even in human children. Individuals, families, companies, and even the nation are beginning to consider such rational measures to prevent obesity.
If you want to live a good life, the ideal diet is one that provides a certain amount of nutrients and is also enjoyable. Of course, you want to make sure you get a certain amount of exercise, but also make it fun. And sleep not only relieves fatigue, but if you can get sleep that secretes a large amount of growth hormone, you will have more energy for the next time. Furthermore, if we can achieve total optimization of life satisfaction, rather than partial optimization of exercise and diet, we will enter a realm of happiness. You want to find a prescription that suits you and live a happy life. It seems that wisdom and reason are required to live this enjoyable life.
