The Color Code is also the title of a book (References, Joseph et al., 2002) combined with a nutritional practice by the same name in another book publication (Heber, 2001). The Color Code combines food science, medical knowledge and nutritional practices to encourage consumer intake of colorful plant foods for achieving optimal health.
