What is the function of minerals in the human body?

Mineral nutrients (dietary minerals) are the chemical elements present in all body tissues and fluids, their presence being necessary for the maintenance of certain physicochemical processes which are essential to life. The mineral elements are separate entities from the other essential nutrients like proteins, fats, carbohydrates, and vitamins and they represent approximately 4% of the body’s mass.  minerals

There are 103 known minerals and at least 18 are necessary for good health.

 Minerals may be broadly classified as macrominerals (calcium, phosphorus, sodium, potassium, magnesium, sulfur and chloride), trace minerals or microminerals (iron, copper, cobalt, iodine, zinc, molybdenum, fluoride, selenium) and ultra trace elements (boron, chromium, arsenic, silicon and nickel).

 What is the function of minerals in the human body?

Though small, minerals are important for a balanced diet. The human body requires minerals to convert food into energy, to prevent dehydration and to regulate the function of the heart and skeletal, muscular and nervous systems.

Macrominerals are needed for proper fluid balance, nerve transmission, muscle contraction; they prevent blood clotting, regulate blood pressure and interfere in the protein metabolism. They ensure the health of teeth, bones and connective tissue.

Trace minerals are essential for growth and development because they are involved in oxygen transport and various metabolic functions. Minerals, like vitamins, function as coenzymes. They participate in all enzyme reactions in the body and help in the assimilation and use of vitamins and other nutrients. Here can help you the keto diet pills.

Minerals deficiencies. Minerals in excess

Mineral deficiency is a reduced level of any of the minerals essential to human health. An abnormally low mineral concentration is usually defined as a level that may impair a function dependent on that mineral. Laboratory studies with animals have revealed that severe deficiencies in any one of the inorganic nutrients can result in very specific symptoms, and finally in losing life, due to the failure of functions associated with that nutrient. In humans, deficiency in one nutrient may occur less often than deficiency in several nutrients. A patient suffering from malnutrition is deficient in a variety of nutrients. The mineral content of the body may be measured by testing samples of blood plasma, red blood cells, or urine or hair.

Minerals deficiencies can occur because the food is not so rich in minerals as it used to be. Fruits, vegetables, and grains grown in mineral deficient soils are mineral deficient. The depletion of minerals from soils has resulted from over farming, overuse of pesticides, herbicides, and fertilizers.

Most common disorders causes by mineral deficiencies are: hypocalcaemia and osteoporosis (calcium deficiency), low calcium in blood (severe magnesium deficiency), anaemia (iron deficiency), poor immune system and increased susceptibility to illness (poor selenium status), goitre (iodine deficiency), hypophosphatemia (low phosphorus levels).

Consuming too many dietary minerals can also harm.

Too much calcium in the blood may cause vomiting, loss of appetite, increased urination, kidney toxicity and irregular heart rhythm. High levels of magnesium in the blood can lead to heart problems or difficulty breathing. Copper poisoning causes vomiting and diarrhea. Toxic levels of selenium are rare but can result in gastrointestinal upset, hair loss, fatigue, irritability and mild nerve damage.

Sources of minerals

Minerals cannot be created by living things, such as plants and animals. They originate in the soil. Minerals are absorbed by plants from the soil and they get into the human organism through diet, directly, when plants containing minerals are eaten, or indirectly from animal sources. Minerals may also be present in drinking water, but the content in these micro nutrients vary from place to place (soil composition is not the same in different locations) and what kind of water used (bottled, tap).

Minerals are best absorbed when taken from in the foods eaten, rather than as a supplement. Good food sources for a number of important minerals are: beans, carrots, pecans, raisins, brown rice, apricots, garlic, spinach, sesame seeds, celery, mushrooms, spinach, apples, tomatoes, strawberries, bananas, lemons, oranges, pineapple, cucumbers, Brussels sprouts, red beets, eggs, tuna, honey, brewers yeast, seafood.

essential minerals and their functions

What are the most important minerals and what they do?

Magnesium. The human body contains about 30 mg of magnesium. It is essentially found in the bones, kidneys, liver, muscles and heart. The normal diet usually provides very little magnesium.

Magnesium is essential for:

  • the transmission of the nervous impulse to the muscles
  • the regulation of the heart’s contractions
  • the efficiency of the immune system
  • the maintenance of the alkalinity of the body
  • the elasticity of the arteries
  • the balance of the nervous system

A deficiency in magnesium causes: tremors, muscles spasms, acidification of the system, hypertension, irritability, nervous tension, stress, infectious diseases, allergies.

The taking of a good supplement of magnesium is recommended as a preventive measure, in the form of a daily basic supplement. You will also profit from taking a supplement of magnesium if you are suffering from one of the following health problems: allergies, anaemia, anxiety, arthritis, cellulite, fracture, gout, hyperactivity, hypertension, infections, insomnia, premenstrual syndrome, sinusitis, stress.

Foods that are a source of magnesium:

Almonds, soybeans, peanuts, hazel nuts, string beans, whole grain bread, peas, whole grain rice, onion, lentils, spinach, pears, peaches, corn, cherries, cabbage, grapes, apples, lettuce, dandelion, plums. Limes, tangerines, grapefruit.

Zinc. The human body contains about three grams of zinc. It is essentially found in the liver, brain, muscles, reproductive organs, pancreas and pituitary gland.

Zinc is essential for:

  • the health of the skin, hair and nails
  • the good functioning of the immune system
  • the production of many enzymes
  • a complete pancreatic action
  • the metabolism of sugars, fats and proteins
  • a complete antioxidant action

A deficiency in zinc causes: weakening of the immune system, problems in healing wounds, prostate disorders, sterility, skin disorders, pituitary gland disorders.

The taking of a good supplement of zinc is recommended as a preventive measure, in the form of a daily basic supplement. You will also profit from taking a supplement of zinc  if you are suffering from one of the following health problems: acne, athlete’s foot, cancer (prevention), eczema, fertility (to improve it), infections, liver spots, prostatitis, psoriasis, sexual impotence. It is beneficial to combine zinc with other substances completing the antioxidant and stimulating action of the immune system.

Foods that are good source of zinc:

oysters, calf liver, lentils, string beans, whole grain bread, whole grain flour, eggs, oat flakes, cod, nuts, mussels, carrot, crab, cabbage, pumpkin, almonds, hazel nuts and garlic.

Some minerals (chlorine, copper, fluorine, iodine and sulphur) do not need to be taken in the form of supplements. They are usually found in sufficient quantities in our normal diet, even sometimes in excess (sodium). However, some particular cases may possibly require that one of these minerals be taken in the form of a supplement.

Copper is essential for: the formation of haemoglobin, the transformations made by liver, the immune system.

Iodine is essential for: the functioning of the thyroid gland, mental growth and development.

Manganese is essential for: the good functioning of the immune system, the metabolism of fats and sugars.

Phosphorus is essential for: the strength of the bone structure, the nervous system.

Potassium is essential for: the balance of the water content of each cell, the maintenance of the alkalinity of the body, the muscles, the heart, the nervous system, the metabolism of protein and fats.

Sodium is essential for: the maintenance of the alkalinity of the body, the water balance throughout the body, the contractions of muscles, the glands producing sweat and saliva.

Sulphur is essential for: the neutralization of toxins (wastes) in the cells, the oxygenation of the cells.
