The word "Pigu" comes from the Taoist method of keeping in good health. In the Tang Dynasty, our ancestors used hunger strike and breathing adjustment to avoid the valley. We can also see from some TV dramas that some hermits often "cross the valley". Our ancestors paid attention to lightness, simplicity and quietness during the valley crossing period. In the process of crossing the valley, you can exercise your will through hunger strike and calm your mind through crossing the valley. This ideal is very good.
However, in recent years, it has been used by many organizations or individuals as a means to seek benefits. Through publicity, more and more people begin to get involved, but many people often find it difficult to stick to it. On the one hand, because they don't eat for a long time, only drink a little water or don't drink at all, the human body can't take in the nutrients needed for life, and it is difficult to maintain a healthy state. Many people get weak when they are hungry, which leads to giving up halfway. There are also many people who worry that eating in the valley is harmful to their health. In fact, this idea is wrong. In the process of crossing the valley, you can eat some fruits and vegetables and drink some light soup, and the intake of staple food can be reduced appropriately. This will not cause harm to the human body.
In addition, not everyone is suitable for health preservation. Inadvertent "fasting" can easily lead to nutritional imbalance in our body, such as low cholesterol and blood lipid, which will affect our central nervous system and cause insufficient nutrition supply in our brain. In the long run, the brain will be sleepy and distracted, which will seriously affect the operation of the brain. Fasting can also stimulate the gastrointestinal tract, which is easy to cause digestive system dysfunction. Some female friends hope to get rid of toxins and lose weight by crossing the valley, but after crossing the valley, with the recovery of our diet, our weight will rebound quickly.
The above are the hazards of broken grain and the edible quality after broken grain. There are various ways to keep healthy now. We can choose other healthier ways to stay healthy, and we don't have to focus on breaking the valley. If some friends insist on keeping healthy, they can break the valley for a day or two first, and then break the valley for a day or two after resuming their diet, or eat more fruits and vegetables and less staple food every day. This is less harmful to the body.
