Essential vitamins for the eye .. Deficiency may cause visual problems!




Are topics of food and nutrition of important topics and knock on the door, especially if vitamins, because the body's integrity depends on the food safety and nutritional value; Since the eye is part of the body they need to be food for its functions to the desired shape.

Vitamins can be defined as an organic compounds work as an organizer for the metabolic processes (metabolism) that occurs within the body. Due Balosacip label vitamins because they are not manufactured in the body, but are obtained from food or additions of Foreign Affairs (synthetic vitamins). The vitamins of the nutrients the body needs in very small quantities to maintain life and to assist in growth.


Subdivision

Vitamins are divided depending on the type of media which melt into two parts, vitamins soluble in fat and soluble in water

Vitamins are soluble in fat
1 -


A soluble vitamins in the middle of greasy before it is absorbed in the blood to carry out its functions, and the surplus stores in the liver; for this reason, the body does not need to supply these vitamins every day. This section is vitamin:

(A) - a, (D) - d, (E) - e, and vitamin K (K)

Vitamins are soluble in water: 2 -

A soluble vitamins in aqueous medium before it is absorbed and the surplus is not stored in the body, but presents with urine. Therefore, the body needs to supply on an ongoing basis through food.


Vitamin group

(B) - b and (C) - c


Under this section.

Vitamins are soluble in water easily lost during storage or food preparation; still have to use special means during storage or preparation of foods rich in these vitamins to reduce the loss, including the cooling of fresh produce, put milk and cereal (maize and wheat) away from strong light also address water resulting from cooking vegetables (broth) soup.

Free radicals

Is a highly reactive molecules that cause significant damage in the tissues of the brain and other body tissues; is a natural result from chemical reactions that occur in the cells of the body.

Produce free radicals, also from sources outside the human body to the sun Kaltard significantly, environmental pollution, unhealthy foods (Kalojbat highways), smoking, drinking alcohol, exposure to radiation and psychological pressure.

Vitamins work with the assistance of enzymes assistance for antioxidants. This in combination with the free radicals within cells, thus reducing the destructive power caused by these roots. It also helps vitamins also used in the restoration of cells from damage caused by oxidation processes.

What are the essential vitamins for the eye?

Essential vitamins for eye health include vitamin A, E, C, B 2, lutein, b 1 and b 12.


Vitamin A (A)

Vitamin "A" of the most important vitamins for the eye

Functions:

Manufacture of dye 1 - a purple pigment found in the optical receptors of the retina called the Rods, composed character is a result of a protein called Opsin with a vitamin. The importance of this dye in the eye as it allows for adjustment during the dark (dark adaptation)


Therefore, any deficiency in this vitamin will adversely affect this adjustment process and, accordingly, will be affected by vision in dim light.

2 - Maintaining the integrity of the tissue lining the surface of the parts of the body (epithelial tissues) and constitute one of the tissue layers of the cornea of the eye.

3 - Since the vitamin "A" is the antioxidant it works to reduce the incidence of cataract in the lens of the eye, especially in the elderly, because the white water is a result of oxidation processes inside the lens, which cause the loss of lens transparency, and thus gradually to consider.

Shortage

1 - the inability to see in dim light is known as the evening night

2 - severe drought for an eye

This includes the emergence of white tissue collected in the part of the conjunctiva

This results in cirrhosis of the tissue cells and surface-called Bitot's spots in addition to dryness, corneal ulceration and eventually lead to blindness

Sources.

- Vitamin "A" only in animal sources such as eggs, liver, meat and dairy products (margarine, butter, yogurt, milk, cheese).


Some plant tissue on the vanguard of vitamin A -

Called carotenoids, beta-carotene are carotenoids of the most effective in giving vitamin "A" and found in most fruits, green leafy vegetables and yellow fruits such as apricots and carrots.

Vitamin E (E)

The importance of vitamin E because it protects all the vitamins are soluble in fat oxidation, by preventing the union with oxygen that leads to a loss of effectiveness. Because this vitamin is an antioxidant, the synthetic forms of it are used to reduce the incidence of white water.

Sources

Often contain most of the food on vitamin E and is cottonseed oil, margarine (vegetable ghee factory) and peanut oil are good sources of this vitamin. Vitamin E is also in the corn, nuts, olives, vegetable oils and green leafy vegetables.


Vitamin C (C)

The level of vitamin C in the eye decrease with aging; but the supply of food rich in this vitamin reduces this shortfall, also vitamin C, vitamin A, as have is he is working to reduce the incidence of white water as an anti-oxidant. It is worth mentioning that the effectiveness of vitamin C a maximum When combined with vitamin E.

Sources

The different kinds of oranges and lemons are excellent sources of vitamin C, as well as tomatoes, strawberries, sweet potatoes, white, green peppers, broccoli, peas, spinach and lettuce.


Vitamin B-2 (B2)

Involving vitamin B-2 enzymes in the installation of two types of escorts enzymes and help escort role in the redox processes that occur within cells; also release energy from carbohydrates, proteins and fats of all these processes to protect the eye as it may help reduce the risk of cataract.

Shortage

- Conjunctivitis


With the appearance of blood vessels around the cornea

- Opacity in the lens of the eye

Sources

Milk and eggs.


Legumes and cereals.

Lean meat and fish.

Green vegetables

Lutein

The list falls under the carotenoids lutein, is present in high concentrations in the center of vision.

Function

Lutein works on the nomination of the blue wavelengths of light coming from the visible light spectrum (the sun). This blue light to cause damage in the cells of the body, which resulted from being one of the productive resources of free radicals within the body and which is characterized by its activity destructive to tissues of the body as we mentioned earlier. Studies have shown that lutein can reduce the development of disease morbidity status of vision associated with aging a disease usually become infected by persons aged 50 years and above, the advantage of being a chronic disease which passes through several development stages, during which various changes of the Centre for Vision ending blindness. Lutein can be considered more useful and effective in reducing the risk of cataract of beta-carotene and lutein, however, that already exists in the lens of the eye, while beta-carotene does not exist within the components of the lens.

Sources

There lutein in broccoli, corn, pumpkins (Humeirra), peas, spinach and green vegetables


Vitamin B-1 and by 12 (B1 & B12)

Is vitamin B 1 (thiamine) and vitamin B-12 vitamins essential for healthy nervous system in addition to vitamin B 12 is important in the formation of red blood cells.

Vitamin B-1 thiamine))

Lack of vitamin B-1 to beriberi and symptoms of this disease occurs in the eye nystagmus, one of the early symptoms of neurological function of the disease, accompanied by microcephaly disorders in other parts of the body.

Vitamin B-1 displays people and alcohol addicts alcohol their bodies to a significant lack of vitamin B 1, because the alcohol to discourage the uptake and storage of this vitamin is good in the body were exposed, personal injury, b

Wernicke-Korsakoff syndrome

Paralysis of the movements Compatibility -

. Eye

The stability of the movement of the pupil - lazy eye food

It occurs in countries that lack her diet of vitamin B-1, and 12 and the disease is characterized by severely impaired vision in the center, which brings attention to the less than 60 / 6 in both eyes with a black spot in the central visual field

In addition to atrophy of the optic nerve with a lack of ability to distinguish colors. It should be noted that smoking prevents improvement of the situation with this disease because it works to discourage the absorption of vitamin B-1, and 12 through the body tissues.

Their sources

Vitamin B-1 in whole grains but vegetables and whole grains, especially rice can also be obtained from meat, fish, legumes, peanuts, fenugreek, mint and parsley. The vitamin B 12 existent, meat, eggs, milk and milk products. So you might suffer vegetarians (those who rely on vegetables and plant foods as food to them) from a lack of vitamin B-12, and that the lack of plants for this vitamin.


Finally

- Although the body to vitamin deficiency may cause serious diseases, however, that the exaggeration in their approach may lead to the most serious diseases threatening human life

- The body needs vitamins supplied in very small quantities need to reverse the carbohydrates, proteins and fats.

- Yes, from God, we say goodbye to these vitamins in most of the creation of the food, so you rarely find these diseases are prevalent only in countries Alradkp under the yoke of poverty.
