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

The recommended minimum protein intake for sedentary, generally healthy individuals is 0.8 grams per kilogram of body mass. This guideline is established to ensure that individuals receive adequate protein for maintaining muscle mass, supporting bodily functions, and promoting overall health.

The rationale behind this recommendation is based on research that indicates this level of protein intake is sufficient for meeting the nutritional needs of most adults, particularly those who are not engaging in regular physical activity or strenuous exercise. In this context, protein plays a critical role in various physiological processes, including tissue repair, enzyme production, and the synthesis of hormones.

Using kilograms as the unit for measuring body mass provides a clearer standard for dietary recommendations, as it is consistent with global nutritional guidelines. This makes it easier for health professionals and individuals to understand and apply the recommendations in practical settings.

The other choices suggest higher amounts of protein, which may be more relevant for active individuals or athletes whose protein requirements are increased to support muscle repair and growth. However, for sedentary individuals, the 0.8 grams per kilogram figure is recognized as adequate to maintain health without unnecessary excess.
