Nutrition intervention refers to strategies designed to improve the nutritional status of individuals or populations through targeted actions such as dietary counseling, food supplementation, education, and policy changes. This research area focuses on identifying effective interventions to address malnutrition, prevent chronic diseases, improve overall health outcomes, and promote healthy eating habits. Nutrition intervention studies often involve monitoring dietary intake, analyzing nutritional biomarkers, and evaluating the impact of interventions on health metrics such as weight, blood pressure, and cholesterol levels. The goal of nutrition intervention research is to inform evidence-based recommendations and public health policies that support optimal nutrition and well-being.
