The climate in late autumn is getting drier and drier. Therefore, the diet in late autumn should be clean and moist, avoid spicy and fragrant products such as ginger, raw onion, raw garlic, pepper and mustard, and eat more foods that moisten the lungs and produce saliva, such as sesame, walnut, honey, pear, sugarcane, persimmon, banana and water chestnut. Although sugar cane and pear can clear lung and moisten dryness, they are not suitable for people with spleen and stomach deficiency and stomachache because of their cold nature.
