Final answer:
A child with AIDS requires a diet that is high in both calories and protein to support their immune system and repair body tissues. Carbohydrates are also essential as they serve as the primary energy source for the body and support various critical functions.
Step-by-step explanation:
A child with AIDS needs a high-calorie and high-protein intake. Proteins are essential for repairing and building body tissues, supporting immune function, and maintaining lean body mass — critical factors for individuals with compromised immune systems, such as those with AIDS. In contrast, a high-protein diet provides the essential amino acids necessary for these processes. Moreover, while carbohydrates are often associated with weight gain when overconsumed, they play a significant role in maintaining good health. Carbohydrates are the body's primary energy source and are crucial for the functioning of the brain, kidneys, heart muscles, and central nervous system. Additionally, they are involved in intestinal health and waste elimination.
