Amino acids are essential to a person's well-being, and there are certain amino acids that can only be obtained through diet. Proteins are organic compounds comprised of amino acids, and are one of the types of macronutrients. While macronutrients are necessary daily in amounts on the order of grams, humans typically only need fewer than 100 milligrams of micronutrients each day. Micronutrients are another essential part of human nutrition and consist of vitamins and dietary minerals such as Vitamin A, copper, iron, and iodine. In this calculator, we only calculate daily carbohydrate, protein, and fat needs. Some definitions also include water, air, calcium, sodium, chloride ions, and some other substances, along with more typical macronutrients, since they are needed in large quantities by the human body. Specifically, they refer to carbohydrates, proteins, and fats. In the context of health and fitness, macronutrients are most often defined to be the chemical compounds that humans consume in large quantities that provide bulk energy.
