evidence: If chicken feeds flu viruses, should you eat the go-to cold-and-flu-meal of chicken soup? The answer is, unfortunately, no. You don't have to scrap the soup altogether though. Remove the chicken and fill the soup with a hearty amount of antiviral and anti-flu foods, including onion, garlic, herbs (thyme, rosemary, and oregano), and veggies (celery, carrots, cabbage, broccoli, cauliflower, zucchini, and bell peppers), and mushrooms. Or, if you really want to keep the chicken in, add even more onion, garlic, herbs, and vegetables to boost the nutritional and antiviral properties. Try this mineral-rich Healing Broth recipe.
