In contrast are the micronutrients, which are not themselves energy sources but facilitate metabolic processes throughout the body: vitamins, of which humans need about 300 milligrams per day in the diet, and minerals, of which about 20 grams per day are needed. The last nutrient category is water, which provides the medium in which all the bodys metabolic processes occur. Most other countries use the kilojoule (kJ) as their standard unit of energy.

Sugars in the diet are monosaccharides, which contain one sugar or saccharide unit, and disaccharides, which contain two saccharide units linked together. The thirteen vitamins are categorized as either water-soluble or fat-soluble. These macronutrients provide raw materials for tissue building and maintenance as well as fuel to run the myriad of physiological and metabolic activities that sustain life. As they digest it, these fecal matter-loving bacteria release gases like hydrogen and methane, and your flatulence may originate from their digestions. Micronutrients are nutrients required by the body in lesser amounts, but are still essential for carrying out bodily functions. Boiled potato During digestion, carbohydrates that consist of more than one sugar get broken down into their monosaccharides by digestive enzymes, and then get directly absorbed causing a glycaemic response (see below). (a disaccharide) and more. In much of the worlds population, lactase activity declines during childhood and adolescence, which leads to an inability to digest lactose adequately. The energy from macronutrients comes from their chemical bonds.
