What is the Recommended Dietary Allowance (RDA) for protein in sedentary individuals?

The Recommended Dietary Allowance (RDA) for protein in sedentary individuals is set at 0.8 grams per kilogram of body weight. This RDA is established based on the amount of protein that is deemed sufficient to meet the nutritional requirements of most healthy individuals and to prevent deficiency.

Protein plays a critical role in various bodily functions, including the maintenance of muscle mass, tissue repair, and enzyme production. The 0.8g/kg figure is based on research that has determined this amount supports nitrogen balance and overall health for those who are not physically active. It's important to note that this recommendation is specific to sedentary individuals, meaning that those who engage in regular physical activity or have higher protein needs, such as athletes or individuals with higher muscle mass, may require a greater intake.

This standard is widely recognized in nutrition guidelines and underscores the importance of protein in the diet while also indicating a baseline requirement for maintaining health in the average adult population.
