Protein is a vital nutrient made of amino acids, often called the building blocks of the body, and includes nine essential amino acids that the body cannot produce and must obtain through dietary protein. The recommended dietary allowance (RDA) for protein intake for an average sedentary adult is 0.8 grams per kilogram of body weight, which translates to about 60 grams of protein per day for a person weighing 165 pounds (75 kilograms).

For minimal/light activity, the recommendation is 1.0 gram of protein per kilogram of body weight. (1) Active individuals, including athletes, may require 1.2 to 2 grams of protein per kilogram of body weight per day, depending on their level of activity. (2)
Protein provides amino acids that help build and repair muscle, skin, hair, and other tissues, while also supporting muscle recovery, immune system function, and overall health. Animal-based protein sources include dairy products, eggs, fish, poultry, and red meat, while plant-based sources include beans, lentils, nuts, seeds, whole grains, and soy products.
