My uncle translated Huangdi Neijing into his own words: "Everything is born on the earth, and the stomach is the stomach of the human body." In order to nourish the stomach, my uncle asked Zhang Zi to cook a pot of wet porridge every morning, sometimes sweet potato porridge, sometimes coix seed porridge, sometimes red date porridge and millet porridge. My uncle doesn't appreciate the rice porridge that people often drink. In his mind, rice is a cold food, so it is better not to drink it often.
Compared with boiled water, porridge will form a warm protective film in the stomach because of putting a little porridge to prevent the food eaten in one day from damaging the gastric mucosa and stomach wall. So you ate a little today. After eating some oily, spicy and sour food, the stomach will not feel so uncomfortable because of this protective film. Over time, your stomach trouble will be very painful. Grandpa's family has many children, but it is because of this health care method that none of their children get stomach trouble. Because I had a good stomach and good health when I was a child. People with good health will have good jobs.
Similarly, Cantonese people like to cook porridge. When you go to their food market every morning, you will find that bones there are more expensive than meat, and you like to hit bones with axes, and even like to eat fish intestines. When I was in the south, my favorite food was preserved egg and lean meat porridge made by them, which was a typical stomach-nourishing porridge, because preserved egg porridge itself strengthened the digestive function of the stomach. Drinking hot porridge and soup often to keep your stomach healthy is better than anything else.
