What percentage of carbohydrates is recommended in a balanced diet?

Carbohydrates are a crucial macronutrient and serve as the body's primary source of energy. In a balanced diet, it is recommended that carbohydrates make up 45-65% of total daily caloric intake. This range is endorsed by various health organizations, including the Dietary Guidelines for Americans, as it supports adequate energy levels for optimal health and functioning.

Within this percentage, a variety of carbohydrate sources should be emphasized, including whole grains, fruits, vegetables, and legumes, which provide not just energy but also essential nutrients and dietary fiber that contribute to overall health. Maintaining this percentage helps in managing weight, blood sugar levels, and overall nutrition, making it essential for a well-rounded diet.

Other ranges provided in the options are inappropriate as they either under-represent the role of carbohydrates in a healthy diet or encompass excessive amounts that may lead to health issues such as increased fat intake or nutrient imbalances.
