List of macronutrients

This list is a categorization of the most common food components based on their macronutrients. Macronutrients can refer to the chemical elements that humans consume in the largest quantities (See Nutrient)

There are three primary macronutrients: carbohydrate, protein, fat, [[]]. Macronutrients are defined as a class of chemical compounds which humans consume in the largest quantities (must be above a threshold amount) and which provide humans with the bulk of energy. While water does make up a large proportion of the total mass ingested as part of a normal diet, it does not provide any nutritional value. Alcohol is a calorically dense compound that can provide large amounts of bioavailable energy although it is not a necessary dietary component.

These 2 essential fatty acids are the starting point for other important omega-acids (e.g. DHA, EPA)

Water is perhaps the most important substance for life on Earth. It provides the medium in which all metabolic processes proceed. As such it is necessary for the absorption of macronutrients, but it provides no nutritional value in and of itself. Water often contains naturally occurring micronutrients such as calcium and salts, and others can be introduced to the water supply such as chlorine and fluoride for various purposes such as sanitation or dental health.

In sports, fitness and bodybuilding the term Macros is used extensively to refer to proteins, carbs and fats. Almost all diet plans are based on judicious distribution of these three elements in required ratios. For example a 2000 calorie diet could consist of 800 calories from 200 grams of protein(1 gram protein = 4 calories), 800 calories from 200 grams of carbs(1 gram carbs = 4 calories) and 400 calories from 44 grams of fats (1 gram fat = 9 calories). This is also called counting or tracking macros.
