What is the current Recommended Dietary Allowance (RDA) for protein for the average adult?

The Recommended Dietary Allowance (RDA) for protein for the average adult is indeed around 0.8 grams per kilogram of body weight. For most adults, this translates to approximately 56 grams per day for men and around 46 grams per day for women. However, dietary guidelines often round these figures, and for practical recommendations, the RDA is often cited as about 60 to 80 grams for an average adult. This means that choosing 80 grams as a guideline represents a generally accepted amount that provides adequate protein intake for maintaining muscle mass, supporting metabolic functions, and overall health.

The other values mentioned, such as 40 grams and 60 grams, may fall short of adequately meeting the protein needs for many individuals, especially in adulthood, where maintaining muscle mass and overall health is crucial. Similarly, while 100 grams may be beneficial for active individuals or specific groups with higher protein needs, it is not considered the general requirement for the average adult population. Therefore, recognizing 80 grams as a suitable standard aligns well with current dietary recommendations for protein intake.
