The best and most natural way to fight infections and to avoid getting sick during cold and flu season is to let your immune system do the work. Your body’s natural defenses are equipped to recognize, attack, and eliminate a number of foreign invaders like bacteria and viruses.
Although your immune system is elegantly designed to fight off sickness, it is not perfect. You can keep it in top fighting form and boost its effectiveness by eating certain foods. When you add those foods to your smoothies, you can make a potent recipe for staying healthy.
