Select the correct answer. When comparing requirements per pound of weight, which nutrient do infants need more of as compared to adults? A. vitamins B. protein C. fats D. minerals E. carbohydrates

Infants have a higher protein requirement per pound of body weight than adults, primarily because they are in a rapid growth phase that demands ample building blocks for new tissues. They need about 1.52 grams of protein per kilogram of body weight, compared to around 0.8 grams for adults. This protein is crucial for muscle development and overall growth, which is why infant formulas are often enriched with this nutrient. Additionally, protein plays a vital role in the production of enzymes and hormones, making it essential for healthy physiological functions. Without adequate protein intake, infants risk stunted growth and developmental delays, emphasizing the importance of meeting their unique dietary needs during these early stages of life.
