What is the recommended dietary allowance (RDA) for protein for sedentary adults?

The recommended dietary allowance (RDA) for protein for sedentary adults is set at 0.8 grams of protein per kilogram of body weight. This guideline is based on data showing the amount needed to meet the nutritional needs of most healthy individuals and to maintain basic physiological functions, muscle mass, and overall health.

This amount takes into account the average protein synthesis rates and the minimum necessary to prevent deficiency in a sedentary population, which includes non-active individuals who do not engage in regular intense physical activity. It provides a benchmark for dietary planning and is critical for understanding the protein needs of the general population, especially in formulating a balanced diet.

Higher protein recommendations apply to specific populations or individuals with increased physical demands, including athletes or those involved in regular intense training, but for the average sedentary adult, 0.8 g/kg is sufficient to support metabolic health and maintain muscle tissue without the risk of excess intake that could occur at higher levels.
