Essential mineral constituents: trace elements and macrominerals in human nutrition

To maintain full physiological functionality, the human organism requires not only fundamental nutritional components such as amino acids, lipids, polysaccharides, or vitamin compounds, but also a range of supplementary chemical substances. These essential constituents enter our system through consumed liquids—primarily drinking water—as well as food products, and may occur in either organic or inorganic compound forms, fulfilling pivotal roles in metabolic processes.

The physiological role of copper in humans: implications of deficiency and excess – biochemical characteristics and functional properties of this trace mineral

Copper represents an indispensable constituent for the proper functioning of all living organisms, playing a pivotal role in growth processes, developmental progression, and the maintenance of systemic homeostasis. Despite being classified as a trace element—present in minute quantities—it participates in critical metabolic, enzymatic, and structural reactions within the body. Both its chronic deficiency and excessive accumulation beyond physiological thresholds can precipitate severe physiological disruptions, thereby emphasizing the necessity of precise regulatory mechanisms governing its systemic balance.

Ingestion and Absorption of Heme and Non-Heme Iron from Food

Iron is a microelement that plays a pivotal role in the supply and transportation of sufficient oxygen to all body tissues. Disruptions in iron provision can result in symptoms such as pale skin, redness of mucous membranes, overall fatigue, and weakness of the body, despite adequate sleep. Iron is characterized by low absorptive capacity from the digestive tract due to numerous factors that decrease its absorption through the digestive system.

Calcium – its function in the body, requirement, and sources

Calcium is one of the essential macrominerals for the body that should be supplied with the daily portion of food. The average required level of this element is around 1000 mg per day and increases with age. Despite the fact that calcium is mainly found in milk and dairy products as well as in green vegetables, there is a persistent deficiency of this element in Poland.
