Which of the following is considered an element of balanced nutrition?

Balanced nutrition encompasses a variety of essential nutrients that the body needs to function properly and maintain health. The correct choice includes proteins, fats, carbohydrates, fibers, vitamins, and minerals, all of which play unique and critical roles in bodily functions.

Proteins are vital for growth, repair, and maintenance of body tissues; fats provide energy and aid in the absorption of fat-soluble vitamins; carbohydrates are the body’s primary energy source; fibers support digestive health and can help regulate blood sugar levels; vitamins are necessary for various biochemical processes; and minerals are essential for bone health, nerve function, and hydration, among other functions.

This combination ensures that the body receives a wide array of nutrients necessary for optimal health, making option C the comprehensive choice that truly reflects what constitutes balanced nutrition. In contrast, the other options emphasize only single types of nutrients, which cannot adequately support the body's diverse dietary needs.
