Minerals play an important role in every bodily function and are present in every human cell. Although the amount needed may be small, without even the trace of the mineral, dysfunction is bound to occur at some level in the body. A zinc deficiency may show up in ridged fingernails with white spots. Lack of sulphur can cause lack-lustre hair and dull-looking skin. Less obvious deficiencies may surface as fatigue, irritability, loss of memory, nervousness, depression and weakness.
Minerals also interact with vitamins. Magnesium, for instance, must be present in the body for utilization of B-complex, C and E vitamins. Sulphur also works with the B-complex vitamins. The body needs all the trace minerals in proper balance.
Coffee, tea, alcohol, excess salt and many drugs can rob the body of minerals or make them ineffective. Industrial pollutants cause toxic minerals to enter the body. Minerals at toxic levels also have the effect of destroying the usefulness of other vitamins and minerals. Exercise improves the activity of certain vitamins and minerals while stress and fatigue work against them.
A well-balanced diet provides as abundance of minerals and vitamins. In refining cereals, grains and sugar, we have robbed them of their natural vitamins and minerals. The dietary sources of these nutrients are whole grains, cereals, bran and germ. It is the bran and germ which are removed in processing. To obtain a balance of nutrients, it’s necessary to avoid refined and processed foods and eat adequate amounts of green leafy vegetables which are an excellent source of many nutrients.
Food medicines are the most powerful way of building health. These basic elements are the 90 minerals and trace elements that make up the earth’s crust. Minerals are vital to health. Like vitamins and amino acids, minerals are essential for regulating and building the trillions of living cells which make up the body. Minerals help maintain the volume of water necessary to life processes in the body. They help draw chemical substances into and out of the cells and they keep the blood and tissue fluid from becoming either too acidic or too alkaline.
The importance of minerals, like vitamins, is illustrated by the fact that there are over 50,000 enzymes in the body which direct growth and energy and each enzyme has minerals and vitamins associated with it. Each of the essential food minerals does a specific job in the body and some of them do extra work, in teams, to keep body cells healthy. The mineral elements which are needed by the body in substantial amounts are calcium, phosphorous, iron, sulphur, magnesium, sodium, potassium and chlorine. In addition the body needs minute (trace) amounts of iodine, copper, cobalt, manganese, zinc, selenium, silicon, fluorine and some others.
The human body needs calcium more than any other mineral. A man weighing 70 kg. contains one kg. of calcium. About 99% of the quantity in the body is used for building strong bones and teeth and the remaining one per cent is used by the blood, muscles and nerves. Calcium performs many important functions. Without this mineral , the contractions of the heart would be faulty, the muscles would not contract properly to make the limbs move and blood would not clot. Calcium stimulates enzymes in the digestive process and coordinates the functions of all other minerals in the body.
Deficiency may cause porous and fragile bones, tooth decay, heart palpitations, muscle cramps, insomnia and irritability. A large increase in the dietary supply of calcium is needed in tetany and when the bones are decalcified due to poor calcium absorption, as in rickets, oesteomalacia and the mal-absorption syndrome. Liberal quantity of calcium is also necessary when excessive calcium has been lost from the body as in hyperparathyroidism or chronic renal disease.
Sources & Daily Requirements of Calcium
Calcium is found in milk and milk products, whole wheat, leafy vegetables such as lettuce, spinach, and cabbage , carrots, watercress, oranges, lemons, almonds, figs and walnuts.
A daily intake of about 0.4 to 0.6 grams of calcium is considered desirable for an adult. The requirement is larger for growing children and pregnant and lactating women.
In the human body, chlorine is liberated by the interaction of common salt, taken along with food, and hydrochloric acid liberated in the stomach during the process of digestion. It is essential for the proper distribution of carbon dioxide and the maintenance of osmotic pressure in the tissues. This food element is necessary for the manufacture of glandular hormone secretions. It prevents the building of excessive fat and auto-intoxication. Chlorine regulates the blood’s alkaline -acid balance and works with Potassium in a compound form. It aids in the cleaning out of body waste by helping the liver to function.
Deficiency of this mineral can cause loss of hair and teeth.
Sources & Daily Requirements of Chlorine
Chlorine is found in cheese and other milk products, green leafy vegetables, tomatoes, all berries, rice, radishes, lentils, coconuts and egg yolk.
Cobalt is a component of vitamin B12, a nutritional factor necessary for the formation of red blood cells. The presence of this mineral in foods helps the synthesis of hemoglobin and the absorption of food iron.
Sources & Daily Requirements of Cobalt
The best dietary sources of cobalt are meat, kidney and liver. All green leafy vegetables contain some amount of this mineral.
No daily allowance has been set. Only a very small amount up to 8 mcg. is considered necessary.
There are approximately 75 to 150 mg. of copper in the adult human body. Newborn infants have higher concentrations than adults. Liver, brain, kidney, heart, and hair contain relatively high concentration. Average serum copper levels are higher in adult females than in males. Serum copper levels also increase significantly in women both during pregnancy and when taking oral contraceptives. This mineral helps in the conversion of iron into haemoglobin. It stimulates the growth of red blood cells. It is also an integral part of certain digestive enzymes. It makes the amino acid tyrosine usable, enabling it to work as the pigmenting factor for hair and skin. It is also essential for the utilisation of vitamin C.
A copper deficiency may result in bodily weakness, digestive disturbances and impaired respiration.
Sources & Daily Requirements of Copper
Copper is found in most foods containing iron, especially in almonds, dried beans, peas, lentils, whole wheat, prunes and egg yolk.
The recommended dietary allowance has not been established but 2 mg. is considered adequate for adults.
Fluorine is the element that prevents diseases from decaying the body. It is a germicide, and acts as an antidote to poison, sickness and disease. There is a strong affinity between calcium and fluorine. These two elements , when combined, work particularly in the outer parts of bones. They are found in the enamel of the teeth and the shiny, highly polished bone surface.
Sources & Daily Requirements of Fluorine
Fluorine is found in goat’s milk, cauliflower, watercress, garlic, beets, cabbage, spinach and pistachio nuts. .
No official dietary allowance has been established for this mineral.
The chief store-house of iodine in the body is the thyroid gland. The essential thyroxin, which is secreted by this gland, is made by the circulating iodine. Thyroxin is a wonder chemical which controls the basic metabolism and oxygen consumption of tissues. It increases the heart rate as well as urinary calcium excretion. Iodine regulates the rate of energy production and body weight and promotes proper growth. It promotes healthy hair, nails, skin and teeth.
Deficiency can cause enlargement of the thyroid glands. Small doses of iodine are of great value in the prevention of goitre in areas where it is endemic and are of value in treatments, at least in the early stages. Larger doses have a temporary value in the preparation of patients with hyperthyroidism for surgical operation.
Sources & Daily Requirements of Iodine
The best dietary sources of iodine are kelp and other seaweeds. Other good sources are turnip greens, garlic, watercress, pineapples, pears, artichokes, citrus fruits, egg yolk and sea foods and fish liver oils.
The recommended dietary allowances are 130 mcg. per day for adult males and 100 mcg. per day for adult females. An increase to 125 mcg. per day during pregnancy and to 150 mcg. per day during lactation has been recommended.
Iron is an important mineral which enters into the vital activity of the blood and glands. Iron exists chiefly as hemoglobin in the blood. It distributes the oxygen inhaled into the lungs to all the cells. It is the master mineral which creates vitality and stamina. It is required for the healthy complexion and for building up resistance in the body.
Iron deficiency is generally caused by severe blood loss, malnutrition , infections and by excessive use of drugs and chemicals. Deficiency of dietary iron may cause nutritional-anemia, lowered resistance to disease, a general run down condition, pale complexion, shortness of breath on manual exertion and loss of interest in sex. Iron is the classic remedy for anemia. However, there are several forms of anemia, and iron deficiency anemia is only one. If one is taking iron pills due to insufficient intake of iron in the normal diet, one should also take at least 40 mg. of folic acid or foliate every day, along with 10 to 25 mg. of vitamin B12. Both these vitamins are essential in building healthy blood cells.
Sources & Daily Requirements of Iron
The chief sources of iron are grapes, raisins, spinach, all green vegetables, whole grain, cereals, dried beans, dark coloured fruits, beets, dates, liver and egg yolk.
An allowance of 20 to 30 mg. of iron in a balanced diet is recommended for an adult.
The human body contains 30 to 35 mg. of manganese, widely distributed throughout the tissues. It is found in the liver , pancreas, kidney, pituitary glands. This mineral helps nourish the nerves and brain and aids in the coordination of nerve impulses and muscular actions. It helps eliminate fatigue and reduces nervous irritability.
A deficiency of this mineral can lead to dizziness, poor elasticity in the muscles, confused thinking and poor memory.
Sources & Daily Requirements of Manganese
Manganese is found in citrus fruits, the outer covering of nuts, grains, in the green leaves of edible plants, fish and raw egg yolk.
No official daily allowance of manganese has been established, but 2 1/2 to 7 mg is generally accepted to be the average adult requirement.
All human tissues contain small amounts of magnesium. The adult human body contains about 25 gms of this mineral. The greater part of this amount is present in bones in combination with phosphate and carbonate. Bone ashes contain less than one per cent magnesium. The bones seem to provide a reserve supply of this mineral in case of shortage elsewhere in the body.
It aids in keeping nerves relaxed and normally balanced. It is necessary for all muscular activity. This mineral is in activator for most of the enzyme system involving carbohydrate, fat and protein in energy-producing reactions. It is involved in the production of lecithin which prevents building up of cholesterol and consequent atheros-clerosis. Magnesium promotes a healthier cardiovascular system and aids in fighting depression. It helps prevent calcium deposits in kidneys and gallstones and also brings relief from indigestion.
Deficiency can lead to kidney damage and kidney stones, muscle cramps, arteriosclerosis, heart attack, epileptic seizures, nervous irritability, marked depression and confusion, impaired protein metabolism and premature wrinkles. Chronic alcoholics often show a low plasma magnesium concentration and a high urinary output. They may, therefore, require magnesium therapy especially in an acute attack of delirium tremens. Magnesium has also proved useful in bladder and urinary problems and in epileptic seizure. This mineral together with vitamin B6 or pyridoxine has also been found effective in the prevention and treatment of kidney stones. Magnesium can be taken in therapeutic doses up to 700 mg a day.
Sources & Daily Requirements of Magnesium
Magnesium is widely distributed in foods. It is a part of the chlorophyll in green vegetables. Other good sources of this mineral are nuts, soya beans, alfalfa, apples, figs, lemons, peaches, almonds, whole grains, brown rice, sunflower seeds and sesame seeds.
The recommended dietary allowances for magnesium are 350 mg. per day for adult man, 300 mg for women and 450 mg during pregnancy and lactation.
It combines with calcium to create the calcium-phosphorus balance necessary for the growth of bones and teeth and in the formation of nerve cells. This mineral is also essential for the assimilation of carbohydrates and fats. It is a stimulant to the nerves and brain. A phosphorous deficiency may bring about loss of weight, retarded growth, reduced sexual powers and general weakness. It may result in poor mineralization of bones, deficient nerve and brain function. While taking calcium in therapeutic doses for calcium deficiency conditions or for treating ailments, it is advisable to take the calcium supplement in which phosphorous has been added in the correct proportions. This is necessary as calcium cannot achieve its objectives unless phosphorous is present in a proper balance.
Sources & Daily Requirements of Phosphorus
Phosphorous is found in abundance in cereals, pulses (lentil), nuts, egg yolk, fruit juices, milk and legumes.
Usually about one gram of phosphorous is considered necessary in the daily diet.
Potassium is essential to the life of every cell of a living being and is among the most generously and widely distributed of all the tissue minerals. It is found principally in the intracellular fluid where it plays an important role as a catalyst in energy metabolism and in the synthesis of glycogen and protein. The average adult human body contains 120 g of potassium and 245 g of potassium chloride. Out of this body potassium, 117 g is found in the cells and 3 g in the extra cellular compartment. Potassium is important as an alkalizing agent in keeping a proper acid-alkaline balance in the blood and tissues. It is essential for muscle contraction and therefore, important for proper heart function. It promotes the secretion of hormones and helps the kidneys in detoxification of blood. Potassium prevents female disorders by stimulating the endocrine hormone production. It is involved in the proper functioning of the nervous system and helps overcome fatigue. It also aids in clear thinking by sending oxygen to the brain and assists in reducing blood pressure. Potassium is also a mineral required for producing healthy sperm in males.
Potassium deficiency may occur during gastrointestinal disturbances with severe vomiting and diarrhoea, diabetic acidosis and potassium-losing nephritis. It causes undue nervous and body tiredness, palpitation of the heart, cloudiness of the mind, nervous shaking of the hands and feet, great sensitivity of the nerves to cold, and excessive perspiration of the feet and hands. In simple cases of potassium deficiency, drinking plenty of tender coconut water daily can make up for it. It is advisable to consume plenty of figs, apricots, prunes, almonds and tomatoes during the use of oral diuretics. Potassium-rich foods should be restricted during acute renal failure and Addison’s disease.
Sources & Daily Requirements of Potassium
Potassium is widely distributed in foods. All vegetables, especially green, leafy vegetables, grapes, oranges, lemons, raisins, whole grains, lentils, sunflower seeds, nuts, milk, cottage cheese and butter milk are rich sources. Potatoes, especially potato peelings, and bananas are especially good sources.
Potassium requirements have not been established but an intake of 0.8 to 1.3 g per day is estimated as approximately the minimum need.
Selenium and vitamin E are synergistic. Selenium slows down aging and hardening of tissues through oxidation. Males seem to have a greater need for this mineral. Nearly half of the total supply in the body is concentrated in the testicles and in the seminal ducts adjacent to the prostate gland. Selenium is useful in keeping youthful elasticity in tissues. It alleviates hot flushes and menopausal distress. It also helps in the prevention and treatment of dandruff.
Deficiency of this mineral can cause premature loss of stamina.
Sources & Daily Requirements of Selenium
This mineral is found in Brewer’s yeast, garlic, onions, tomatoes, eggs, milk and sea food.
There is no official dietary allowance for selenium but, 50 to 100 mcg is considered adequate.
This is known as the ” beauty mineral ” as it is essential for the growth of skin, hair shafts, nails and other outer coverings of the body. It also makes the eyes bright and assists in hardening the enamel of the teeth. It’s beneficial in all healing processes and protects the body against many diseases such as tuberculosis, irritations in mucous membranes and skin disorders.
Deficiency can lead to soft brittle nails, aging symptoms of skin such as wrinkles, thinning or loss of hair, poor bone development, insomnia, osteoporosis.
Sources & Daily Requirements of Silicon
Silicon is found in apples, cherries, grapes, asparagus, beets, onions, almonds, honey, peanuts and the juices of the green leaves of most other vegetables.
No official dietary allowance has been established for this mineral.
Sodium Chloride , the chemical name for common salt, contains 39 per cent of sodium, an element which never occurs in free form in nature. It is found in an associated form with many minerals especially in plentiful amounts with chlorine. It acts with other electrolytes, especially potassium, in the intracellular fluid, to regulate the osmotic pressure and maintain a proper water balance within the body. It is a major factor in maintaining acid-base equilibrium, in transmitting nerve impulses, and in relaxing muscles. It is also required for glucose absorption and for the transport of other nutrients across cell membranes. Sodium can help prevent catarrh. It promotes a clear brain, resulting in a better disposition and less mental fatigue. Because of its influence on calcium, sodium can also help dissolve any stones forming within the body. It is also essential for the production of hydrochloric acid in the stomach and plays a part in many other glandular secretions. There is some natural salt in every food we eat.
Both deficiency and excess of salt may produce adverse effects to the human body. Deficiencies of sodium are, however, rare and may be caused by excessive sweating, prolonged use of diuretics, or chronic diarrhoea. Deficiency may lead to nausea, muscular weakness, heat exhaustion, mental apathy and respiratory failure. Over-supply of sodium is a more common problem because of overuse of dietary sodium chloride or common salt. Too much sodium may lead to water retention, high blood pressure, stomach ulcers, stomach cancer, hardening of arteries and heart disease. In case of mild deficiency of sodium chloride, taking a teaspoon of common salt in one half litre of water or any fruit juice quickly restores the health. In severe conditions, however, administration of sodium chloride in the form of normal saline by intravenous drip may be restored to. The adverse effects of excessive use of sodium chloride can be rectified by avoiding the use of common salt.
Cramps in the limbs can sometimes be due to lack of salt due to sweating from intense exercise. A small teaspoon of salt in water or a fruit juice can bring almost instant relief.
Sources & Daily Requirements of Sodium
Vegetable foods rich in sodium are celery, cucumbers, watermelon, lemons, oranges, grapefruit, beet-tops, cabbage, lettuce, corn, apple, berries, pears, squash, pumpkin, peaches, lentils, almonds and walnuts. Animal food sources include shell fish, lean beef, kidney, bacon and cheese.
All living matter contains some sulphur ; this element is therefore essential for life. The greater part of the sulphur in the human body is present in the two sulphur-containing amino acids, methionine and cysteine, or in the double form of the latter cystine. The main purpose of sulphur is to dissolve waste materials. It helps to eject some of the waste and poisons from the system. It helps keep the skin clear of blemishes and makes hair glossy. It is also valuable in rheumatic conditions.
Deficiency of sulphur may cause eczema and imperfect development of hair and nails. Sulphur creams and ointments have been remarkably successful in treating a variety of skin problems.
Sources & Daily Requirements of Sulphur
The main sulphur-containing foods are radishes, carrots, cabbage, cheese, dried beans, fish and eggs.
There is no recommended dietary allowance but a diet sufficient in protein will generally be adequate in sulphur.
There are about two grams of zinc in the body where it is highly concentrated in the hair, skin, eyes, nails and testes. It is a constituent of many enzymes involved in metabolism. Zinc is a precious mineral. Our need for this mineral is small but its role in growth and well-being is enormous, starting before birth. It is needed for healthy skin and hair, proper healing of wounds, successful pregnancies and male virility. It plays a vital role in guarding against diseases and infection. It is needed to transport vitamin A to the retina. There are 156 enzymes that require zinc for their functioning. Growth and sexual maturity depend on zinc.
Deficiency can result in weight loss, skin diseases, loss of hair, poor appetite, diarrhea and frequent infection. Those suffering from rheumatoid arthritis may have a zinc deficiency. Heavy drinkers lose a lot of zinc in their urine.
Sources & Daily Requirements of Zinc
The main dietary sources of zinc are milk, liver, beans, meat, whole grains, nuts, and seeds. The recommended dietary allowance of zinc is 15 mg daily.
