Because the fineness and delicacy of food need not only processing, but also chewing slowly to get food nutrition. More importantly, in the process of chewing this body "processing", people who are willing to spend time will certainly not be greedy. The "satiety center" of the brain has enough time to complete the nerve reflex, so it is enough to produce satiety, so it will send out a nerve instruction not to eat any more.

Therefore, a major element of modern health care is to chew slowly. According to the law of nutrition, it is best to chew 30 times per bite. This kind of chewing certainly avoids overeating caused by overeating, but it is estimated that few people can do it.

The importance of chewing slowly

If a person has been eating flour and rice, he should increase the proportion of coarse grains and change his diet structure. On the contrary, if you always eat coarse grains, you may get enough cellulose, but protein is not enough, so he needs to eat more flour and rice, and even lean meat.

The same was true in the Confucius era. The reason why he put forward "food is not tired of essence" is because the food at that time was not exquisite enough, and "not tired" belongs to a kind of life pursuit. On the contrary, if we were surrounded by exquisite food like ours, we would have been tired of it.

Then in a life dominated by coarse grains, eating a few meals of flour and rice lean meat is absolutely in line with the nutritional ratio. This law still applies today, but our balance cycle is not a lifetime, but a week, and it is best to find it within this week, whether it is plain or rough.

For example, eating and drinking in the first half of the week or at noon, then going home for dinner in the second half of the week or at night, eating coarse grains and vegetarian food, is more conducive to a balanced nutrition.
