What are the three macronutrients?

The three macronutrients are carbohydrates, proteins, and fats. These macronutrients are essential components of our diet that provide the energy needed for the body to function.

Carbohydrates are the body's primary source of energy. They are broken down into glucose, which is used to fuel bodily functions and physical activity. Proteins play a vital role in building and repairing tissues, as well as in producing enzymes and hormones necessary for various bodily processes. Fats are also an important energy source and are crucial for absorbing certain vitamins (A, D, E, and K), cushioning organs, and regulating body temperature.

Other options listed, such as vitamins, minerals, and fiber, are important for health but are classified as micronutrients or non-caloric components of the diet, rather than macronutrients. Therefore, while they contribute to overall nutrition, they do not serve the same energy-providing role as carbohydrates, proteins, and fats.
