Vitamin A

The various functions of common vitamins, their deficiency symptoms, natural sources, daily requirements and their therapeutic uses are discussed in brief as follows:

Vitamin A

Known as anti-opathalmic, vitamin A is essential for growth and vitality. It builds up resistance to respiratory and other infections and works mainly on the eyes, lungs, stomach and intestines. It prevents eye diseases and plays a vital role in nourishing the skin and hair. It helps to prevent premature ageing, increases life expectancy and extends youthfulness. The main sources of this vitamin are fish liver oil, liver, whole milk, curds, pure ghee, butter, cheese, cream and egg yolk, green leafy and certain yellow root vegetables such as spinach, lettuce, turnip, carrot, cabbage and tomato and ripe fruits such as prunes, mangoes, papaya, apricots, peaches, almonds and other dry fruits. A prolonged deficiency of vitamin A may result in inflammation of the eyes, poor vision frequent colds, night blindness and increased susceptibility to infections, lack of appetite and vigour, defective teeth and gums and skin disorders.

Importance of Vitamins, Indian Naturopathy

       

In Naturopathy, there is a great importance of Vitamins. Vitamins are potent organic compounds which are found in small concentrations in foods.

            Vitamine` meaning a vital amine, is of great importance in Naturopathy. Vitamins are potent organic compounds which are found in small concentrations in foods and perform specific and vital functions in the body chemistry. Except for a few exceptions, they cannot be manufactured or synthesised by the organism and their absence or improper absorption results in specific deficiency disease. It is not possible to sustain life without all the essential vitamins. In their natural state they are found in minute quantities in organic foods. Vitamins, which are of several kinds, differ from each other in physiological function, in chemical structure and in their distribution in food.

            Vitamins are broadly divided into two categories, namely, fat-soluble and water-soluble. Vitamins A, D, E and K are all soluble in fat and fat solvents and are therefore, known as fat-soluble. They are not easily lost by ordinary cooking methods and they can be stored in the body to some extent, mostly in the liver. They are measured in international units. Vitamin B Complex and C are water soluble. They are dissolved easily in cooking water. A portion of these vitamins may actually be destroyed by heating. They cannot be stored in body and hence they have to be taken daily in foods. Any extra quantity taken in any one day is eliminated as waste.

Fluorine

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. Fluorine is found in goat`s milk, watercress, garlic, cauliflower, beets, cabbage, spinach and pistachio.

Minerals thus 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.

Silicon

Silicon is indispensable for the growth of skin, hair shafts, nails and other outer coverings of the body. It also makes the eyes bright and helps in hardening the enamel of the teeth. It is advantageous in all healing process and protects body against many diseases such as tuberculosis, irritations in mucous membranes and skin disorders. Silicon is found in apples, cherries, honey, grapes, asparagus, beets, onions, almonds, peanuts and the juices of the green leaves of most other vegetables. Deficiency can lead to soft brittle nails, ageing symptoms of skin such as wrinkles, thinning or loss of hair, poor bone development, insomnia and osteoporosis.

Zinc & Selenium

Zinc
There are about two grams of zinc in the body where it is extremely concentrated in the eyes, nails, hair, skin and testes. Zinc is a precious mineral. 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. The main dietary sources of zinc are beans, meat, whole grains, milk, liver, nuts, and seeds. Deficiency can result in weight loss, skin diseases, and loss of hair, poor appetite, Diarrhoea and frequent infection. Those suffering from rheumatoid arthritis may have a zinc deficit.

Selenium
Selenium and vitamin E are synergistic and the two together are stronger than the sum of the equal parts. Selenium slows down ageing and hardening of tissues through oxidation. 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. This mineral is found in Brewer`s yeast, garlic, onions, tomatoes, eggs, milk and sea food. Deficiency of this mineral can cause premature loss of stamina.

Cobalt & Manganese

Cobalt
Cobalt is a component of vitamin B12, a nutritional factor required for the formation of red blood cells. The presence of this mineral in foods helps the synthesis of haemoglobin and the absorption of food- iron. The best dietary sources of cobalt are meat, kidney and liver. All green leafy vegetables contain some amount of this mineral.

Manganese
The human body contains 30 to 35 mg. of manganese, widely distributed throughout the tissues. It is found in the pancreas, kidney, liver, pituitary glands. This mineral helps nurture the nerves and brain and aids in the coordination of nerve impulses and muscular actions. It helps get rid of fatigue and reduces nervous irritability. Manganese is found in citrus fruits, the outer covering of nuts, grains, in the green leaves of edible plants, fish and raw egg yolk. A deficiency of this mineral can lead to poor elasticity in the muscles, confused thinking, dizziness, and poor memory.

Copper

                 There are approximately 75 to 150 mg. of copper in the adult human body. Newborn infants have higher concentrations than adults. This mineral helps in the conversion of iron into haemoglobin. It stimulates the growth of red blood cells. It is also a fundamental 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 necessary for the utilisation of vitamin C. Copper is found in most foods containing iron, particularly in almonds, peas, lentils, whole wheat, dried beans, prunes and egg yolk. A copper insufficiency may result in bodily weakness, digestive disturbances and impaired respiration.
