After beginning of autumn, Yang declined and Yin rose, and nature began to change from growth to collection. According to the principle of four seasons, yin qi is nourished in autumn and winter. Autumn is dry, qi dryness hurts the lungs, and lung qi deficiency reduces the body's tolerance to bad stimuli and is prone to diseases, so it is necessary to moisten dryness, nourish yin and moisten the lungs.
Eat more sour food, less spicy food, help liver qi, and eat more foods that calm the liver and moisten the lungs, such as lily, lotus root, potato, radish, fungus, yam, lentil, medlar, tremella, pork, duck, chicken, rabbit, peanut, eel, crucian carp, yellow croaker, grapefruit, pear, apple and so on.
Autumn is a season suitable for tonic, but we should choose products that are "dry and not greasy", such as pumpkin, lotus seeds, longan, black sesame, red dates and walnuts.
