Adolescent nutrition is a specialized field within nutritional science dedicated to understanding the unique physiological, metabolic, and behavioral aspects of dietary intake and nutritional status during the adolescent period (typically ages 10-19 years). This research area investigates the specific nutrient requirements for rapid growth, pubertal development, and maturation, analyzes prevalent dietary patterns and their determinants, and evaluates the impact of nutritional status on physical health, cognitive function, and long-term disease risk, recognizing adolescence as a critical window for establishing lifelong health trajectories.
