Public health nutrition focuses on the promotion of good health through nutrition and the primary prevention of nutrition-related illness in the population.
The goal is to safeguard and improve the nutritional status of populations via interventions and policies that address the broader social and environmental determinants of health.
Public health nutrition encompasses a variety of strategies, including health promotion, disease prevention, and intervention programs that are designed to improve dietary practices and nutritional status at the community, national, or global level.
