Human nutrition
The protein requirement for each individual differs, as do opinions about whether and to what extent physically active people require more protein. The 2005 Recommended Dietary Allowances (RDA), aimed at the general healthy adult population, provide for an intake of 0.8 grams of protein per kilogram of body weight. A review panel stating that "no additional dietary protein is suggested for healthy adults undertaking resistance or endurance exercise."
High-protein diet
A high-protein diet is low in fat or carbohydrate consumption, and is not the same as a low-carbohydrate diet which may not be food-energy–controlled and may include fat. Example foods in a high-protein diet include lean beef, chicken or poultry, pork, salmon and tuna, eggs, and soy. A diet is considered "high in protein" if daily protein consumption exceeds 15% of total energy intake.
