Chicken Soup
Why it’s a cold/flu fighter: When you have a cold or the flu, a major symptom includes congestion in the nose, chest, and throat. Chicken soup has specifically been shown in studies to thin mucus secretions. Broth and noodles provide carbohydrates for maintaining your energy levels, potentially helping you feel less lethargic. If you add vegetables, you’ll boost the level of nutrients in the soup, which will help support immune function. Slurp away on low- sodium soups that contain 30% less salt. You want the soup to contain some salt, though, because sodium helps regulate the amount of fluid in the body. Basically, the saltiness in soup may help encourage hydration, says Lawrence D. Rosen, MD, chair of the Integrative Pediatrics Council, and author of The Whole Child blog. This is important because fevers can contribute to dehydration.
鸡汤
普通感冒和流感都有鼻塞、咽部不适的感觉，其实这是病毒引起上呼吸道炎症的表现。很多研究已经验证了鸡汤的抗感冒作用：鸡汤能够减少呼吸道分泌炎性液体；肉汤和面条内含有碳水化合物，为患者提供能量，患者才不会总是昏昏欲睡；如果在鸡汤里加点蔬菜，营养会更丰富，对提高自身免疫力很有帮助；鸡汤里含有少量的盐，这对感冒病人也是有益的。因为盐里的钠离子可以促进水合作用，而感冒病人发烧时身体往往会脱水。
