Four dietary knowledge of spring health preservation
Spring is coming. We know that the weather in spring is changeable, sometimes cold and sometimes hot. Health care in spring is particularly important. If you don't pay attention, there will be various minor health problems. I remind MM not to eat fruit blindly, and don't forget the balance of diet and nutrition.

The first expert said: it is not advisable to eat fruit blindly in spring.

Fruit is everyone's favorite food, but there are certain stresses on eating fruit. Eating fruit blindly will do harm to your health. Let me tell you what to pay attention to when eating fruit. Excessive consumption of fruit will lead to copper deficiency in human body, increase cholesterol in blood and cause coronary heart disease. Therefore, it is not advisable to eat too much fruit in a short time. Some people think that the vitamin content in the peel is higher than that in the pulp, so when eating fruit, eat it with the skin. As we all know, when fruit is damaged by diseases and insect pests, pesticides are often sprayed, which will soak and remain in the wax of the peel, so the pesticide residue in the peel is much higher than that in the pulp.

The second expert suggested that the diet should raise yang.

Yang refers to the yang of the human body, which one does Chinese medicine think? Yang is the spirit, who is outside? In other words, yang plays a defensive role in the human body, which can make the human body strong and avoid the invasion of six evils in nature. In spring, in terms of diet, we should follow the advice of Huangdi Neijing? Make up yang in spring and summer? The principle is to eat more foods that warm and tonify the yang, so as to enrich the yang, enhance the body's resistance, and resist the invasion of pathogenic factors dominated by wind and evil. Li Shizhen also advocated in Compendium of Materia Medica? Eat a mixture of tender vegetables, such as onion, garlic, leek, Polygonum hydropiper, Artemisia, mustard, etc. . On the other hand, because kidney yang is the foundation of human yang, supplementing yang in diet should also include warming and tonifying kidney yang. In spring, the yang of the human body is sufficient on the body surface, but insufficient in the body, so we should eat more things that nourish kidney yang in our diet. At present, in addition to Polygonum hydropiper, Artemisia annua and other wild vegetables have been rarely eaten, onions, garlic, leeks and so on are all good yang-nourishing products.

The third expert said: Drink more water at ordinary times.

Drinking water can increase the circulating blood volume, which is beneficial to nourishing the liver and excreting metabolic waste, and can reduce the damage of poisons to the liver. In addition, hydration is also beneficial to gland secretion, especially the secretion of digestive juice such as bile. Drinking scented tea in spring is helpful to dispel the cold evil accumulated in the body in winter, promote the hair growth of human yang, and stagnate and evacuate. Moderate drinking tea can also refresh you, but don't be greedy for cold drinks in spring.

The fourth expert stressed: eat more sweets and eat less sour.

Sun Simiao, a famous doctor in Tang Dynasty, said? In spring, you should keep sour, sweeten and nourish your temper. ? It means that when spring comes, people should eat less sour and more sweet, which has the benefits of strengthening the spleen and stomach. Traditional Chinese medicine believes that the spleen and stomach are the foundation of the day after tomorrow and the source of qi and blood metaplasia. Spleen and stomach are vigorous and can prolong life. However, spring is a season of vigorous liver qi. According to the theory of five elements in traditional Chinese medicine, liver belongs to wood, spleen belongs to soil, and wood and soil coexist, that is, liver depression can hurt spleen and affect its digestion and absorption function. Chinese medicine also believes that five flavors enter the five internal organs, such as sour taste into the liver, sweet taste into the spleen and salty taste into the kidney. Therefore, eating more sour food will strengthen the function of the liver, make the hyperactive liver qi more vigorous and hurt the spleen and stomach. In view of this, people should eat less sour food in spring to prevent excessive liver qi. And sweets into the spleen, can make up the temper, so you can eat more, such as jujube, yam, crispy rice and so on.
