Minerals in the body: role, balance and importance for health
Minerals are inorganic substances that enter the human body with food and water and are involved in most vital processes. They are not produced by the body on their own, so they must come from outside.
The importance of minerals is difficult to overestimate: they are part of bones and teeth, participate in muscle contraction, heart rate regulation, nervous system function, metabolism, and hormonal balance.
Main groups of minerals
It is customary to distinguish two large groups:
Macronutrients — needed in relatively large quantities (calcium, magnesium, potassium, sodium, phosphorus).
Micronutrients (trace elements) — needed in small doses, but are important (iron, zinc, copper, iodine, selenium, manganese, chromium).
The role of essential minerals
| Mineral | Main function | Sources | Consequences of the deficit |
|---|---|---|---|
| Calcium (Ca) | Formation of bones and teeth, blood clotting, heart function | Dairy products, broccoli, almonds | Osteoporosis, cramps, brittle nails |
| Magnesium (Mg) | Regulation of the nervous system, energy metabolism | Nuts, cocoa, legumes, whole grains | Convulsions, insomnia, increased anxiety |
| Potassium (K) | Control of water-salt balance, muscle and heart function | Bananas, potatoes, legumes | Heart rhythm disturbances, weakness |
| Iron (Fe) | Hemoglobin formation, oxygen transport | Meat, liver, spinach, legumes | Anemia, weakness, decreased immunity |
| Iodine (I) | Synthesis of thyroid hormones | Seafood, iodized salt | Hypothyroidism, goiter, decreased intelligence in children |
| Zinc (Zn) | Immunity, wound healing, hormone synthesis | Pumpkin seeds, seafood, meat | Growth retardation, skin problems, infertility |
| Selenium (Se) | Antioxidant protection, thyroid support | Brazil nuts, fish, eggs | Weakened immunity, risk of cancer |
Mineral balance in the body
A lack or excess of minerals is equally dangerous. For example:
excess calcium can lead to kidney stones;
excessive sodium (salt) consumption causes hypertension;
Excess iron causes liver and heart damage.
Therefore, it is important to support balance through a balanced diet, and take supplements only on the recommendation of a doctor after examinations.
When to check mineral levels
The doctor may advise you to take tests in cases of:
chronic fatigue;
seizures, sleep problems;
frequent colds and weakened immunity;
impaired hair and nail growth;
thyroid problems;
cardiac arrhythmias.
Among the tests used: a complete blood count, biochemical analysis, ionogram, and analysis of the mineral composition of hair.
How to maintain adequate mineral levels
eat a variety of foods - vegetables, fruits, dairy products, meat, seafood, nuts, cereals;
limit excess salt and sugar;
follow a sufficient drinking regimen;
monitor the condition of the intestine, because it is there that digestion takes place;
If necessary, use vitamin and mineral complexes under the supervision of a doctor.
Minerals are the invisible "builders" of health. They are responsible for bones, heart, brain, hormones, and even mood. Proper nutrition and regular checking of trace element levels are an easy way to strong immunity and longevity.
