Final answer:
The Institute of Medicine recommends that 10-35% of an adult's daily caloric intake should come from protein. This accounts for the essential role protein plays in growth, cell repair, and metabolic processes, and varies with the level of athletic training and energy requirements.
Step-by-step explanation:
The Institute of Medicine's Acceptable Macronutrient Distribution Range for protein is 10-35% of daily caloric intake for adults, which aligns with the notion that dietary protein is crucial for growth, cellular repair, and various metabolic processes. This range accommodates for periods of growth, such as infancy and adolescence, and is based on the essential role that protein plays in building new cells and providing amino acids post-digestion. It's especially important for individuals experiencing growth spurts to consume adequate protein for optimal health.
A balanced diet, according to the Institute of Medicine, includes not only protein but also carbohydrates, fats, vitamins, and minerals to meet the body's needs. The institute's guidelines of 10-15% calories from protein, 20-30% from fat, and 50-70% from carbohydrates present a framework for constructing a nutritious eating plan. This composition ensures the provision of energy, support for metabolic reactions, and the maintenance, growth, and repair of muscles, especially during periods of intense training or exercise. The recommended daily intake of protein for general health and for athletes varies, supporting different bodily functions and training requirements.
