What are the six major nutrients required by the human body?

The six major nutrients required by the human body are carbohydrates, proteins, fats, vitamins, minerals, and water. These nutrients play essential roles in various bodily functions.

Carbohydrates are a primary source of energy for the body, providing fuel for brain function and physical activity. Proteins are crucial for building and repairing tissues, and they serve as the body's structural components and enzymes. Fats provide a concentrated source of energy and are important for hormone production and the absorption of certain vitamins.

Vitamins and minerals are essential for numerous biochemical reactions; they support immunity, bone health, and overall cellular function. Water, while often overlooked, is vital as it facilitates various bodily processes including temperature regulation, nutrient transport, and waste elimination.

While the other options present different combinations of these nutrients, they inaccurately list others that are not classified as essential nutrients. For instance, sugars and fiber are types of carbohydrates but do not encompass the full range of required nutrients listed in the correct answer. Similarly, while amino acids are critical components of proteins, they do not stand alone as a separate nutrient category. Recognition of all six major nutrients is key to understanding a balanced and healthy diet.
