Micronutrients: Types, Functions, Benefits and More
Micronutrients are one of the major groups of nutrients your body needs. They include vitamins and minerals. Vitamins are necessary for energy production, immune function, blood clotting and other functions. Meanwhile, minerals play an important role in growth, bone health, fluid balance and several other processes. This article provides a detailed overview of micronutrients, their functions and implications of excess consumption or deficiency. Your body needs smaller amounts of micronutrients relative to macronutrients.

Water-soluble vitamins travel freely through the body, and excess amounts usually are excreted by the kidneys. The body needs water-soluble vitamins in frequent, small doses. These vitamins are not as likely as fat-soluble vitamins to reach toxic levels. But niacin, vitamin B6, folate, choline, and vitamin C have upper consumption limits.

What are the 6 essential nutrients?
Vitamin , any of several organic substances that are necessary in small quantities for normal health and growth in higher forms of animal life. Vitamins are distinct in several ways from other biologically important compounds such as protein s, carbohydrate s, and lipid s. Although these latter substances also are indispensable for proper bodily functions, almost all of them can be synthesized by animals in adequate quantities. Vitamins, on the other hand, generally cannot be synthesized in amounts sufficient to meet bodily needs and therefore must be obtained from the diet or from some synthetic source. For this reason, vitamins are called essential nutrients.
In the context of nutrition, a mineral is a chemical element required as an essential nutrient by organisms to perform functions necessary for life. Nutrient minerals, being elements, cannot be synthesized biochemically by living organisms. The trace elements that have a specific biochemical function in the human body are sulfur , iron , chlorine , cobalt , copper , zinc , manganese , molybdenum , iodine , and selenium. Most chemical elements that are ingested by organisms are in the form of simple compounds. Plants absorb dissolved elements in soils, which are subsequently ingested by the herbivores and omnivores that eat them, and the elements move up the food chain.
The body needs many minerals; these are called essential minerals. Essential minerals are sometimes divided up into major minerals macrominerals and trace minerals microminerals. These two groups of minerals are equally important, but trace minerals are needed in smaller amounts than major minerals. The amounts needed in the body are not an indication of their importance. A balanced diet usually provides all of the essential minerals. The two tables below list minerals, what they do in the body their functions , and their sources in food.

Minerals are specific kinds of nutrients that your body needs in order to function properly. The human body requires different amounts of each mineral to stay healthy. Specific needs are outlined in recommended daily allowances RDA. The RDA is the average amount that meets the needs of about 97 percent of healthy people.
There are six essential nutrients that people need to consume through dietary sources to maintain optimal health. The WHO divide these essential nutrients into two categories: micronutrients and macronutrients. Micronutrients are nutrients that a person needs in small doses.

Я знаю, - услышала Сьюзан собственный едва слышный голос. - Нам нужна ваша помощь. Она с трудом сдерживала слезы. - Стратмор… он… - Мы знаем, - не дал ей договорить Бринкерхофф.
Черт возьми! - Он отшвырнул паяльник и едва не подавился портативным фонариком. - Дьявольщина. Джабба начал яростно отдирать каплю остывшего металла. Она отвалилась вместе с содранной кожей. Чип, который он должен был припаять, упал ему на голову.
