SACRAMENTO, Oct. 12 (UPI) -- Hand washing and cough covering are important in avoiding the flu but some foods also help fight flu, a U.S. dietitian advises.
"It's important to eat a variety of healthy foods from all food groups throughout the year, but it's particularly significant during flu season," Andrea Garen, a registered dietitian says in a statement. "Adding flu-fighting foods like yogurt, garlic, citrus and chicken to your diet can boost your body's immune system and help you to avoid getting sick."
