The lungs are always healthy.

Traditional Chinese medicine believes that the lungs are particularly delicate and vulnerable to exogenous pathogens, which are called "wind, cold, heat, dampness, dryness and heat", and Chinese medicine calls them six evils. Therefore, the lungs are afraid of both cold and dryness, and even more afraid of heat. Once attacked by external evils, diseases will take advantage of it, and pulmonary nodules are one of them. Therefore, it is necessary to moisten the lungs as early as possible, especially in autumn and winter.

The so-called five colors enter the five internal organs, and white corresponds to the lungs. Therefore, if you want to moisten and nourish your lungs, you should eat more white food, and lotus root is one of them. Autumn is the season when lotus root is abundant, which is suitable for cooking or stewing soup, such as lotus root ribs soup, three fresh sweet soup (lotus root, lotus seed and lily) or glutinous rice lotus root. However, it should be noted that lotus root can be divided into crisp lotus root and powder lotus root, which is more suitable for cooking because of its high starch content. To sum up, the value of lotus root is still very high. It can not only clear and moisten the lungs, but also strengthen the spleen and nourish the stomach.

Lotus root is also called Miao Yin cuisine. Li Shizhen once said in Compendium of Materia Medica that "Lotus root is sweet, delicious and nontoxic, which can relieve vexation, relieve fever, promote blood circulation and remove blood stasis. Lotus root is crisp and tender, which can be fried, mixed, steamed and fried, and is deeply loved by Hubei people and Anhui people. In addition, it also contains a variety of protein, vitamins and crude fiber, and has high nutritional value.

Euryale ferox, also known as "chicken head rice", belongs to a kind of food that grows on the water. The chicken's head rice is grayish white, and its fruit and stem are edible, which can be used for soup or porridge. However, it should be noted that the fruit of chicken head rice is hard, and it is best to crush it with a pressure cooker. In addition, the chicken's head rice can strengthen the spleen and nourish the stomach, and it also helps to eliminate dampness.

Zizania latifolia is a kind of Chinese herbal medicine and a vegetable growing in water. It is recorded in Compendium of Materia Medica that Zizania latifolia can clear away heat and quench thirst, remove yellow eyes, facilitate defecation, stop dysentery and relieve alcoholism. It can be seen that Zizania latifolia has extremely high medicinal value. In addition, the fresh water bamboo is very fresh and tender when fried.

Water chestnut is one of the less common fruits because of its crisp and sweet taste and high nutritional value. Compendium of Materia Medica holds that water chestnut is sweet, slightly cold, slippery and non-toxic, and has the functions of "quenching thirst, relieving summer heat, warming the middle warmer, invigorating qi, releasing the heart, expelling wind and detoxifying, and removing excess heat in the chest, which can be used as powdery food. In addition, its starch content is extremely high, which can be used for making vermicelli and brewing wine, and can relieve cough, eliminate phlegm, induce diuresis and relieve sore throat.
