A common cold is a viral infection of the upper respiratory system; the nose and throat. Since there is no treatment, the body’s immune system is responsible for making antibodies to fight the infection. Somebody with low immune function will be more prone to catching colds.
Supporting the immune system involves stress management, exercise and a healthy diet. Nutrients can help fight infection and prevent illness. The ‘immune boosting’ diet consists of brightly colored foods high in antioxidants.
