Spurenmineralien

Spurenmineralien, also known as trace minerals, are chemical elements that are essential for the proper functioning of living organisms, but are required in very small quantities. Despite their low concentrations, they play crucial roles in a wide array of biological processes. These include acting as cofactors for enzymes, participating in metabolic pathways, facilitating oxygen transport, and contributing to the structural integrity of tissues.

The definition of a trace mineral is based on the amount required by an organism, rather than their abundance in the Earth's crust. For example, iron, while relatively abundant in the Earth's crust, is considered a trace mineral for humans because the body only needs a small amount, yet it is vital for oxygen transport in red blood cells. Other examples of trace minerals include zinc, copper, manganese, iodine, selenium, and chromium.

Deficiencies in trace minerals can lead to a variety of health problems. For instance, a lack of iodine can result in goiter and impaired thyroid function, while iron deficiency causes anemia. Conversely, excessive intake of some trace minerals can also be toxic. Therefore, maintaining a balanced intake through diet is essential. Many foods contain trace minerals, and their bioavailability can vary depending on the food matrix and the individual's digestive system. Understanding the importance and dietary sources of these essential micronutrients is key to overall health.
