NCBI Bookshelf. Trace elements or trace metals are minerals present in living tissues in small amounts. Some of them are known to be nutritionally essential, others may be essential although the evidence is only suggestive or incomplete , and the remainder are considered to be nonessential.

Minerals: Their Functions and Sources

Human body requires certain essential elements in small quantities and their absence or excess may result in severe malfunctioning of the body and even death in extreme cases because these essential trace elements directly influence the metabolic and physiologic processes of the organism. Rapid urbanization and economic development have resulted in drastic changes in diets with developing preference towards refined diet and nutritionally deprived junk food. Poor nutrition can lead to reduced immunity, augmented vulnerability to various oral and systemic diseases, impaired physical and mental growth, and reduced efficiency. Diet and nutrition affect oral health in a variety of ways with influence on craniofacial development and growth and maintenance of dental and oral soft tissues. Oral potentially malignant disorders OPMD are treated with antioxidants containing essential trace elements like selenium but even increased dietary intake of trace elements like copper could lead to oral submucous fibrosis. The deficiency or excess of other trace elements like iodine, iron, zinc, and so forth has a profound effect on the body and such conditions are often diagnosed through their early oral manifestations. This review appraises the biological functions of significant trace elements and their role in preservation of oral health and progression of various oral diseases.

The dietary requirement for an essential trace element is an intake level which meets a specified criterion for adequacy and thereby minimizes risk of nutrient deficiency or excess. Disturbances in trace element homeostasis may result in the development of pathologic states and diseases. Although various classifications for trace elements have been proposed and may be controversial, this review will use World Health Organization WHO classification as previously done. The results indicated that for the known essential elements, essentiality and toxicity are unrelated and toxicity is a matter of dose or exposure. Little is known about the essentiality of some of the probably essential elements. In regard to toxic heavy metals, a toxic element may nevertheless be essential. In addition, the early pathological manifestations of trace elements deficiency or excess are difficult to detect until more specific pathologically relevant indicators become available.


Deficiencies or excess states of semi-major elements often result in water and electrolyte abnormalities. Essential trace elements of the human body include zinc .


Trace Elements in Human Nutrition (II) – An Update

Trace elements analysis is a fundamental challenge in environmental sciences. Scientists measure trace elements in environmental media in order to assess the quality and safety of ecosystems and to quantify the burden of anthropogenic pollution. Among the available analytical techniques, X-ray based methods are particularly powerful, as they can quantify trace elements in situ.

Jump to content. 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.

Body composition may be analyzed in various ways. This can be done in terms of the chemical elements present, or by molecular type e. In terms of tissue type, the body may be analyzed into water, fat, connective tissue , muscle , bone, etc. In terms of cell type, the body contains hundreds of different types of cells, but notably, the largest number of cells contained in a human body though not the largest mass of cells are not human cells, but bacteria residing in the normal human gastrointestinal tract. Only about 0.

Composition of the human body

Models that describe the trace element status formation in the human organism are essential for a correction of micromineral trace elements deficiency.

Trace elements are naturally occurring inorganic substance required in humans in amounts < mg/day. They are essential components of.

Elements are present in different forms in the nature, and these elements are very essential for the body to perform different functions.
