Public health is the ability to use organized community action to achieve a life of good condition by preventing disease, promoting health, and extending lifespan. It is achieved through effective citizen action, diagnosis, and treatment (Winslow 1920). Public health promotes good health, which can be accomplished by preventing diet-related diseases in the population. It is about applying knowledge to solving nutrition-related health problems. Nutrient scientists emphasize that nutrition is not solely a research topic but also an issue that requires resolution. Therefore, the solution to nutritional problems requires a multidisciplinary approach. The public health nutritionist’s knowledge base has developed over time and incorporated insights from various fields such as physiology, biology, biochemistry, national basic sciences, and social anthropology to comprehend the eating habits of diverse societies worldwide. Scientific research is crucial in addressing nutritional problems as it highlights the importance of understanding the basic mechanisms of nutritional metabolism and how this problem can be solved. A strategy that focuses on community engagement in combating malnutrition emphasizes enabling local community to take an active role in creating and executing strategies to resolve malnutrition challenges. biochemistry, national basic sciences, and social anthropology to comprehend the eating habits of diverse societies worldwide.
