Micronutrient requirements generally increase during the transition from childhood to adolescence primarily due to the significant physical and physiological changes that occur during this period. Adolescence is marked by growth spurts, increased muscle mass, and the initiation of sexual maturation, all of which demand a higher intake of essential vitamins and minerals to support these processes.
For instance, calcium and vitamin D are crucial during adolescence to optimize bone growth and peak bone mass, which is vital for long-term skeletal health. Likewise, iron needs also rise, particularly in adolescent girls due to menstrual blood loss and the overall increased demand during periods of rapid growth.
Additionally, other micronutrients such as zinc, magnesium, and various B vitamins play important roles in supporting metabolic processes, energy levels, and overall well-being during adolescence. Therefore, the increased requirement for these micronutrients highlights the importance of a balanced diet that can meet the needs of the growing adolescent body.
