What is the recommended minimum protein intake for sedentary, generally healthy individuals?

  1. 0.5g per kilogram of body mass

  2. 0.8g per kilogram of body mass

  3. 1.0g per kilogram of body mass

  4. 1.2g per kilogram of body mass

The correct answer is: 0.8g per kilogram of body mass

The recommended minimum protein intake for sedentary, generally healthy individuals is 0.8 grams per kilogram of body mass. This guideline is based on nutritional studies that have established the amount of protein necessary to maintain overall health and prevent deficiency in this population. This intake level is sufficient to support the maintenance of muscle mass, enzyme production, and numerous other bodily functions without the need for excessive protein, which can be unnecessary for those who are not highly active. Individuals with higher activity levels, such as athletes or those engaged in intense training, typically require more protein to support muscle repair and growth, which is why other options suggest higher amounts. However, for the average sedentary person, 0.8 grams per kilogram strikes a balance between adequate nutrition and practicality, aligning with dietary recommendations from health organizations. This ensures that individuals meet their protein needs without the risk of accumulating excess that can burden the body.
