Chicken Soup

Believe it or not, your grandmother was right: Chicken soup is the perfect snack when you've got a cold! Not only is the warm broth comforting and soothing (essential when you're feeling run down and uncomfortable), research at the Nebraska Medical Center in Omaha showed that chicken soup helps control the production and spread of inflammation and congestion-causing neutrophils (white blood cells). A cup of this soup gives you the perfect "dose."
