What percentage of daily calories should proteins account for in a balanced diet?

Proteins should account for 10-35% of daily calorie intake in a balanced diet, making this range the correct response. This recommendation is based on guidelines from reputable health organizations that emphasize the importance of protein as a macronutrient necessary for growth, repair, and overall function of the body.

Protein plays several critical roles, including building and repairing tissues, producing enzymes and hormones, and supporting immune function. Consuming an adequate amount of protein is essential for maintaining muscle mass, especially during weight management or aging.

The suggested range of 10-35% ensures that individuals receive enough protein while allowing for adequate intake of carbohydrates and fats, which are also vital for health. A diet that is too low in protein may not provide sufficient building blocks for maintaining bodily functions, while excessively high protein consumption beyond this range may lead to health issues, particularly affecting kidney function over time.

In contrast, the other options do not accurately reflect the recommended range for protein intake within a balanced diet, either being too low, which may lead to deficiencies, or too high, which can pose health risks.
