What is a commonly accepted range of daily protein intake for healthy adults?

The commonly accepted range of daily protein intake for healthy adults is approximately 0.8 grams per kilogram of body weight. This recommendation is based on the average needs of sedentary adults to maintain health and support bodily functions, including the repair and maintenance of muscle tissues, hormone production, and immune function. This value is derived from extensive research and guidelines from health organizations that focus on the nutritional requirements necessary to sustain physical health in the general population.

Those who lead a more active lifestyle or are involved in endurance sports may require higher protein intake levels to support muscle repair and recovery, which is why values like 1.0 or 1.2 grams per kilogram might be referenced in specific contexts; however, for the average adult, 0.8 grams remains the baseline recommendation. This makes it essential to understand the general nutrient requirements and how they can vary based on individual lifestyle factors, activity levels, and overall health goals.
