Final answer:
The recommended percentage of macronutrient intake for protein is generally 15% of total daily calories, but individual needs may vary, especially for athletes.
Step-by-step explanation:
The recommended percentage of macronutrient intake for protein is 15% of your total daily calories. Protein is an essential nutrient, especially during periods of rapid growth, such as infancy and adolescence. While these figures are general guidelines, it is important to note that everyone's dietary needs may vary, especially for athletes or individuals with special dietary considerations. For athletes, the amount of protein needed can range from 1.2 to 2.0 g/kg/day depending on the level of training and specific bodily requirements.
