Which of the following are classified as macronutrients?

Macronutrients are essential nutrients that provide the energy necessary for the body's functions and are needed in larger quantities compared to micronutrients, which include vitamins and minerals. The classification of macronutrients typically includes carbohydrates, lipids (fats), proteins, and water.

Carbohydrates serve as the body's primary source of energy. They are broken down into glucose, which is utilized by cells. Lipids are another vital source of energy and are crucial for the absorption of certain vitamins and the production of hormones. Proteins play a key role in the structure, function, and regulation of body tissues and organs and are made up of amino acids. Water, while often overlooked in dietary discussions, is essential for many physiological processes, including digestion and temperature regulation.

In contrast, vitamins and minerals are classified as micronutrients, which support various bodily functions but are required in smaller amounts. Additionally, while fibers are a type of carbohydrate and can contribute to health, they are not typically classified as a macronutrient in the same way that carbohydrates, proteins, and fats are. Amino acids are the building blocks of proteins and nucleic acids are fundamental to genetic information, but they do not represent macronutrient categories on their own.

Thus, the classification
