Question

which of the following dietary modifications should an adolescent who participates in sports implement?
increase fats to 30% to 40% of daily kilocalories.
drink water before and after sports activities.
keep protein intake at the same level.
decrease carbohydrates to 30% to 40% of daily kilocalories.

Explanation:

• For the option "Increase fats to 30% to 40% of daily kilocalories": The recommended fat intake for adolescents (and generally) is around 25 - 35% of daily calories, so increasing to 30 - 40% is not a standard recommendation for sports - participating adolescents.
• For the option "Drink water before and after sports activities": Hydration is crucial for athletes (including adolescent athletes) before, during, and after sports to prevent dehydration, maintain performance, and support recovery. This is a valid and important dietary (hydration) modification.
• For the option "Keep protein intake at the same level": Adolescents involved in sports typically have increased protein needs for muscle growth, repair, and energy during exercise, so keeping protein intake the same is not appropriate.
• For the option "Decrease carbohydrates to 30% to 40% of daily kilocalories": Carbohydrates are the main source of energy for sports and physical activity. A decrease to 30 - 40% is too low as athletes (including adolescent athletes) need a higher proportion of carbohydrates (usually 45 - 65% of daily calories) to fuel their activity.

Answer:

B. Drink water before and after sports activities.
