Chicken soup: Chicken contains carnosine, which is anti-inflammatory. Plus, the broth keeps you hydrated, while the steam can relieve symptoms of congestion. Pumpkin and sesame seeds: They’re high in zinc, which is known to boost immune function. Banana: High in vitamin B6, which boosts the immune system, bananas are full of loads of other nutrients as well to help your body fight a cold. Fish: Fish may not be the first thing you crave with a cold, but the omega-3 fatty acid found in mackerel, tuna, sardines, and salmon can reduce inflammation and potentially relieve pain brought on by your cold. Yogurt & kefir: While you want to avoid most dairy when you have a cold, yogurt and kefir are the exception, as both contain immune-boosting nutrients. Foods high in vitamin C: Try bell peppers, strawberries, pineapple, and broccoli, in addition to the ubiquitous citrus fruits. Vitamin C–rich foods boost immune function, helping you recover faster. Foods high in vitamin E: Vitamin E also helps your immune system run efficiently, so try these E-rich foods: broccoli, spinach, almonds, and blueberries. Foods high in selenium: Selenium is another important immune-boosting nutrient. Find it in shrimp, tuna, turkey, lamb, beef, chicken, eggs, and brazil nuts.
