Myth #3: The idea that eating chicken soup can zap a cold is just an old wives' tale.

Your mom or grandmother may have raised you to believe that there’s something magical about chicken soup when it comes to treating a cold or flu, but is it true? Yes, says Dr. Sharp. “Turns out, there’s some real science behind this,” he says, explaining that chicken soup may have a positive effect on the immune system with something called neutrophil aggregation—which means “bringing white blood cells together.” White blood cells help fight off infection in your body and are integral to helping you feel better faster. While it’s not clear if other broths or hot beverages have similar immune system benefits, Dr. Sharp says hot liquids like tea and broth can help reduce the symptoms of a cold or flu virus, relieving sinus and throat pain.
