When planning care for an adolescent who plays sports, which modification should the nurse include in the care plan?

A) Increasing carbohydrates to 55% to 60% of total intake
B) Providing vitamin and mineral supplements
C) Decreasing protein intake to 0.75 g/kg/day
D) Limiting water before and after exercise

Sports and regular moderate to intense exercise necessitate dietary modification to meet increased energy needs for adolescents. Carbohydrates, both simple and complex, are the main source of energy, providing 55% to 60% of total daily kilocalories. Protein needs increase to 1 to 1.5 g/kg/day. Fat needs do not increase. Adequate hydration is very important. Adolescents need to ingest water before and after exercise to prevent dehydration, especially in hot, humid environments. Vitamin and mineral supplements are not required, but intake of iron-rich foods is required to prevent anemia.
