What percentage of the daily recommended intake of protein do adults need?

Adults are generally required to consume a specific percentage of their daily caloric intake from protein to support essential bodily functions, including muscle repair, enzyme production, and overall health. The recommended dietary allowance (RDA) for protein varies based on several factors such as age, sex, and level of physical activity, but a common guideline suggests that protein should make up about 10% to 35% of total daily calories.

The response indicating 20% of protein aligns well with various dietary guidelines suggesting that aiming for around 15-25% can be beneficial for most adults, particularly for those engaged in regular physical activity or muscle-building practices. This range helps ensure that individuals get adequate protein to maintain health while also allowing for a balanced intake of carbohydrates and fats.

While 10% is lower than generally recommended and may not sufficiently support the needs of individuals, especially those with higher physical demands, 35% may be excessively high for many adults and could lead to imbalances in nutrient intake if not properly managed.

Therefore, maintaining a protein intake of approximately 20% balances the need for adequate protein while allowing for other macronutrient sources in one's diet.
