IV. Life Stages
Changes with age: Adolescence
Adolescence is associated with intense anabolism (growth spurt, increased lean body mass).
Data on which to base recommendations for adolescents are sparse. The following are clearly important, and risk of deficiency is real:
- Energy -- for growth and development (total caloric need is maximum here, since fairly large individuals are growing rapidly).
- Protein -- for growth and development.
- Iron and zinc -- to support increasing red cell, muscle and skeletal mass.
- Calcium, to support increasing skeletal mass.
Obesity and eating disorders can be serious problems. These will be discussed later in the course.
