Public health nutrition is any organized measure to promote health, prevent disease and prolong the life of a population according to the World Health Organization 1. Public health was established to protect the well-being of a whole population rather than a single individual. Public health nutritionists focus on eliminating a disease or health issue among a community by educating communities through nutrition education 1.

Mission of Public Health Nutrition
