Minerals are components of inorganic food that cannot be produced by the body itself. Minerals are essential (vital) components of all living cells and are involved in the metabolism.
The proportion of minerals in the human body is about 4% of body weight.
Minerals are differentiated according to the amount in which they occur in the body. Volume elements are minerals that are contained in the human body at more than 50 mg per kg of body weight. Trace elements are minerals that make up less than 50 mg per kg of body weight. The quantity elements are often referred to as minerals (as on this page) also in contrast to the trace elements.
Humans need minerals for many functions, eg. As for the build-up of body substance (bones, muscles) and the maintenance of enzyme activities.
Purpose of minerals in the body:
- Minerals are part of the skeleton and teeth. They give the bones the strength.
- Minerals affect in dissolved form, as electrolytes, vital properties of body fluids, eg. B. Maintenance of osmotic pressure.
- Minerals are essential components of organic compounds in the body. Iodine is part of the thyroid hormone, cobalt of vitamin B12, iron of hemoglobin, etc.
Minerals in food:
How high the mineral content of various foods depends not least on how many minerals contained the soil on which the plant grew or what the animal got to eat. It should also be noted that some nutrients may have a beneficial or inhibiting effect on mineral intake.
