What is the recommended intake range for protein?

The recommended intake range for protein is typically around 10% to 35% of total daily calories, but the most commonly cited guidelines for a balanced diet suggest that protein is best maintained within the 15% to 25% range. This level supports the body's protein needs for maintenance, growth, and repair, especially in populations with varying requirements, such as athletes and growing children. Consuming protein within this range helps ensure an adequate intake of essential amino acids while also allowing for a balanced intake of carbohydrates and fats, which are also vital for overall health.

The selected range strikes a balance that supports muscle synthesis, hormonal production, and immune function without excessive intake that might lead to negative health outcomes. Protein is an essential macronutrient, and adhering to these recommendations helps people meet their nutritional needs effectively while reducing the risk of potential side effects associated with both inadequate and excessive protein consumption.
