Which of the following is a recommended source of protein for growing adolescents?

Lean meats are considered a recommended source of protein for growing adolescents due to their high-quality protein content, which is essential for growth, muscle development, and overall health during this critical stage of life. Protein plays a vital role in building and repairing tissues, making it especially important for adolescents who are experiencing rapid physical changes and increased activity levels.

In addition to providing necessary protein, lean meats are rich in other important nutrients such as iron and B vitamins. Iron is crucial for the formation of red blood cells and energy production, while B vitamins support metabolic processes. Including lean meats in a balanced diet can help ensure that adolescents meet their increased nutritional needs during growth spurts.

Other options, while having their benefits, do not provide the same level of protein necessary for adolescents. Chips are generally high in unhealthy fats and low in nutritional value, whole grain bread contains some protein but lacks the complete amino acid profile found in animal sources, and fruit juices provide sugars and vitamins but minimal protein. Therefore, lean meats are the most appropriate choice for supporting the dietary needs of growing adolescents.
