Final answer:
The RDA for protein is based on preventing protein deficiency, and eating below the RDA can lead to protein deficiency.
Step-by-step explanation:
The RDA for protein is based on the rationale of preventing protein deficiency. Protein is one of the essential nutrients that provide the raw materials for producing new cells, and it plays a crucial role in growth and development. The RDA ensures that individuals consume enough protein to meet their body's needs for growth, maintenance, and repair of muscles and other tissues.
If you eat below the RDA for protein, it can lead to protein deficiency. Protein deficiency can result in various health problems, such as muscle loss, weakened immune system, delayed growth in children, and impaired wound healing. It is important to consume an adequate amount of protein to support optimal health and well-being.
