Adolescence, spanning from ages 13 to 18 years, is a crucial period of physical development and growth. During this time, the body undergoes significant changes in composition, metabolism, hormones, and organ system maturation, as well as nutrient deposit establishment. These changes may impact future health. In terms of nutrition, adolescence is also a critical time for establishing a lifelong relationship with food, particularly with regards to the connection between diet, exercise, and body image. During adolescence, individuals face challenges related to time management due to school, training, work, and social commitments.
