Essential nutrients are substances the body must get from foods because it cannot manufacture them at all or fast enough to meets its needs. Nonessential nutrients are substances the body can make in sufficient quantities (e. g. cholesterol) Non-energy-producing nutrients assist in releasing energy from energy-producing nutrients. 1kcal = amount of energy needed to heat 1l of water by 1 c. We almost always say calorie, even though a calorie is 1,000x smaller than a kcal. 3 of the 6 essential nutrients supply energy.
