N: 1. From word-forming element macro- and word nutrient:

  • macro-: word-forming element meaning «long, abnormally large, on a large scale,» taken into English via French and Medieval Latin from Greek makros «long, large,» from PIE root *mak- «long, thin.»
  • nutrient (n.): “a nutritious substance,” 1828, noun use of adjective (1640s) meaning “providing nourishment,” which is from Latin nutrientem (nominative nutriens), present participle of nutrire “to nourish, suckle, feed,” from PIE nu-tri-, suffixed form (with feminine agent suffix) of (s)nau– “to swim, flow, let flow,” hence “to suckle,” extended form of root sna- “to swim.”
  1. A necessary nutrient required in relatively large amounts (in grams) by the body.
  2. Macronutrients are nutrients that provide calories or energy and are required in large amounts to maintain body functions and carry out the activities of daily life. There are three broad classes of macronutrients: proteins, carbohydrates and fats.

In nutrition, macronutrients are those nutrients that together provide the vast majority of metabolic energy to an organism. The three main macronutrients are carbohydrates, proteins, and fat. Others include alcohol and organic acids. They are distinguished from micronutrients such as vitamins and minerals necessary in small amounts to maintain health but not to provide energy.

  1. The energy consumed in food is supplied by three macronutrients: carbohydrates, proteins, and fats. Under- or overconsumption of individual macronutrients may increase a person’s risk of chronic diseases such as obesity, coronary heart disease, type 2 diabetes, and cancer. 

Macronutrients provide the body with energy, help prevent disease, and allow the body to function correctly. Macronutrients are available in many food sources, but it can be difficult to determine the right amount to consume. There are also a number of factors that can influence the quantity of macronutrients people may need.
