Mikrotähteet

Mikrotähteet, also known as trace elements, are chemical elements that are essential for the growth and development of living organisms, but are required in very small amounts. Despite their low concentrations, they play crucial roles in various biological processes. For humans, these include functions like enzyme activity, hormone synthesis, and oxygen transport.

Common examples of mikrotähteet in human nutrition include iron, zinc, copper, manganese, iodine, selenium, and molybdenum. Iron is vital for hemoglobin production, which carries oxygen in the blood. Zinc is important for immune function and wound healing. Iodine is essential for thyroid hormone production, which regulates metabolism.

These elements are typically obtained through a balanced diet, with different foods containing varying amounts of specific mikrotähteet. Deficiencies can lead to a range of health problems. For instance, iron deficiency causes anemia, while iodine deficiency can result in goiter and developmental issues. Conversely, excessive intake of certain mikrotähteet can also be harmful, leading to toxicity. Therefore, maintaining an appropriate balance is key for health. In agriculture, mikrotähteet are also important for plant growth, and their absence in soil can limit crop yields.
