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: protein, fat, and carbohydrate. 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.
These 2 essential fatty acids are the starting point for other important omega-acids (e.g. DHA, EPA)
Though a provider of energy, alcohol is not necessary for survival, so it is not a macronutrient.
