magnesium
The human body needs a healthy, balanced and integrated diet so that it can live a healthy lifestyle, resist the pressures of daily life, reduce the risk of chronic diseases and maintain overall health. To be healthy, the diet should contain all the nutrients including carbohydrates, proteins, Vitamins, and mineral salts, and magnesium is one of the basic elements needed by the human body.
Magnesium is one of the mineral salts that must be present in the diet. Magnesium is the fifth mineral element in terms of the amount of its presence in the human body. The adult body contains 20 to 28 g of magnesium, which is the second mineral salts in terms of its quantity. In cells, and present in all cells of the body, concentrated in bones containing 60% of the magnesium in the body, then in the muscles containing 26%, and the rest is in the soft tissues and body fluids, and works magnesium in the bones as a reserve store To maintain its rate in the blood.
Daily needs of magnesium by age group
The recommended daily needs are based on the intake of food, while the upper limit is based on non-nutritive sources such as dietary supplements:

Symptoms of magnesium deficiency in the body
Magnesium deficiency is rare due to its wide spread in food, and it usually appears only with the presence of diseases such as alcoholism, protein malnutrition, kidney disorders, vomiting, long-term diarrhea, dyspepsia and absorption. They eat diuretics, and lead to the lack of severe symptoms of the following on the human:
- Muscle spasm (contractions and cramps in muscles).,
- Dysfunction in the work of the central nervous system, which can explain the hallucinations that occur as a withdrawal of alcohol.
- Differences in personality.
- Nausea, vomiting and loss of appetite.
- May cause coma.
- Hypothyroidism and hypothyroidism in response to bone and kidneys of this hormone.
- Lack of calcitriol hormone (active form of vitamin D) and resistance to vitamin D.
- Bone dysfunction in young people or osteoporosis in older persons.
- Magnesium deficiency increases the risk of high blood pressure and cardiovascular disease.
Magnesium functions in the body
- There is 60% of the body’s magnesium in the bones, it plays an important role in its composition, and increases the high intake of magnesium from bone density.
- It plays a key role in the energy representation processes, as it adds another phosphate atom to AT. It therefore plays a key role in the body’s ability to use glucose, fat synthesis, proteins, nucleic acids, and transport systems in cell membranes.
- He works as an adjunct to more than 300 enzymes involved in the representation of food components and the formation of many compounds resulting from metabolism.
- Is very important in protein synthesis processes within soft tissue cells.
- Calcium co-regulates the work of muscle contractions and blood clotting, as calcium stimulates these processes while magnesium inhibits them and thus relaxes the muscles.
- Magnesium in its functions with calcium also maintain blood pressure and in the functioning of the lungs.
- Works to prevent tooth decay by keeping calcium in the teeth.
- It has a role in supporting the work of the immune system.
- It has a role in transmitting nerve impulses and normal functioning of the nervous system.
- It may have a role in preventing atherosclerosis and heart disease but this use needs more scientific research to prove it.
- Studies have found an effective role for magnesium in lowering blood pressure in people with high blood pressure.
- Helps to support the work of insulin, and magnesium is one of the reasons for the positive effect of eating whole grains on the work of insulin.
- Magnesium is used to treat high blood pressure in pregnant women with preeclampsia, and is used to treat pre-eclampsia.
Magnesium absorption and transfer and put
Approximately 35% to 45% of the magnesium intake in the small intestine is absorbed, especially in the fasting part, by both simple diffusion and transport diffusion. The body’s effectiveness in magnesium absorption varies according to its state of the body, the quantity of the diet and the composition of the diet. The level of magnesium in the blood is controlled by absorption in the intestines and subtraction in the kidneys and the entry and exit of tissue cells, and there is no effect of any hormone it, and the kidneys to reduce the drop of magnesium in the urine when it is low, while rising in the case of high intake as in the case Dietary supplements, and also less in cases of breastfeeding for the high need of the body.
Sources of magnesium
Magnesium is found in good quantities in legumes, seeds, cashews, peanuts, whole grains, and green vegetables as part of chlorophyll, such as spinach, broccoli, cocoa, and some fish. Milk is a medium source of magnesium. It is a good source of diet, and fruits other than bananas are considered to be low sources of magnesium as well as meat.
Magnesium toxicity
Magnesium poisoning is very rare, especially when taken from food sources. However, if it occurs, it is very dangerous and may cause death. Therefore, the maximum limit of intake of non-food sources such as supplements has been determined and toxicity has been shown only in smelters exposed to inhalation or ingestion of high amounts of Magnesium dust.
