Necessary for tissue formation, cell reparation, and hormone and enzyme production. Micronutrients play many essential roles in the body. There are three classes of macronutrients: carbohydrates, lipids, and proteins. At their most basic, carbohydrates are made of building blocks of sugars, and can be classified according to how many sugar units are combined in their molecule.

Foods also contain non-nutrients that may be harmful (such as natural toxins common in plant foods and additives like some dyes and preservatives) or beneficial (such as antioxidants). Without it, nothing could be transported in or out of the body, chemical reactions would not occur, organs would not be cushioned, and body temperature would fluctuate widely. This chemical energy is converted into cellular energy that is then utilized to perform work, allowing our bodies to conduct their basic functions. Glucose is then transported to all our cells where it is stored, used to make energy, or used to build macromolecules. European Journal of Clinical Nutrition 61:S5-S18.
