Vitamin E Deficiency Impacts
Who may require a higher dose intake or to prevent vitamin E?
There is rarely a lack of vitamin E. If this happens, it manifests itself in specific cases primarily are distinguished three situations:
* Individuals who have difficulty absorbing fat or secrete bile or suffering from some disorder in the metabolism of fats (celiac disease and cystic fibrosis)
* Premature babies (with very low birth weight) weighing less than 1500 grams
* Individuals with genetic abnormalities in transporter proteins of alpha tocopherol
Also vitamin E levels may drop due to a lack of zinc.
Symptoms of vitamin E deficiency
* Irritability
* Fluid retention
* Hemolytic anemia (destruction of red blood cells)
* Eye disorders
* Nervous system damage Read the rest of this entry »
The Benefits of Vitamin E
* Antioxidant: Vitamin E is a natural antioxidant that reacts with lipid-soluble free radicals in the cell membrane. Thus maintaining the integrity of the cells to provide protection to the presence of toxic compounds, heavy metals (silver, mercury, lead), drugs and radiation.
The toxicity of these foreign substances is given by the free radicals that are generated during the detoxification (detox) in the body.
* Immune system, plays an important role in maintaining healthy immune system, especially during oxidative stress and chronic viral diseases. Induces cell proliferation and increases defense cellular response to damage or infection.
* Oxidative Stress: Oxygen can sometimes be harmful because it acts on the molecules of the body making them very reactive. When these molecules become so reactive begin to damage cellular structures around them.
The cells do not use all the oxygen that enters them but a small portion of that oxygen is converted into forms harmful chemicals called free radicals are very unstable and react with nearby cells causing great damage, altered function, aging and destroying them.
It is caused by an imbalance between production of free radicals and the body’s ability to remove excess. His knowledge is the foundation of all antioxidant therapies, including ozone therapy. Read the rest of this entry »
Nutriotion Foods: Vitamin E
Brief definition
Also called tocopherol, fat-soluble vitamin essential for the organism is an antioxidant that helps protect the fatty acids. So the body takes care of the formation of toxic molecules resulting from normal metabolism as entered by the respiratory or oral. Avoid abnormal destruction of red blood cells, prevents eye disorders, anemia and heart attacks.
It is mainly found in egg yolk, vegetable oils germ (soybean, peanut, rice, cotton and coconut). Green leafy vegetables and cereals and breads.
Are not customary excesses or defects of this vitamin in the body if their use tends to be proportional to fatty acids. Since its presence removes toxins, helps remove body entered by smokers. The daily required dose for children is 10 IU and 25 IU for adults. Read the rest of this entry »
Nutrition Foods: Vitamins
Vitamins are essential for the various species, since they can not be synthesized in the body that is precisely what defines it as such: the need for their presence in the diet.
Between 1906 and 1912 the great English biochemist Sir Frederick Hopkins, who proposed to unknown substances we call vitamins called “accessory food factors.”
Everything started when they began to study why certain diseases were produced and came to the conclusion that the various complaints are generated by the lack of certain substances: shortcomings.
In those years did not know the chemical structure of vitamins, but if they knew that some were associated with fatty food components (fat-soluble vitamins), and others to the aqueous (water-soluble vitamins).
The discovery of vitamins has written one of the most brilliant of modern science and has been the result of close collaboration between different scientific disciplines.
Toxicity of Vitamin A
Toxic effects of excessive intake of vitamin A
Hypervitaminosis A refers to an abnormal deposition in the body in large amounts of vitamin A (retinol).
Normally this is given by the excessive intake of vitamin supplements.
There are several side effects among which are:
* Birth defects: is when the supplement that has high doses of retinol ingested for a while, several days or weeks and especially during the first trimester of pregnancy.
* Abnormalities in the liver.
* Reduced bone mineral density.
* Central nervous system disorders.
Signs and symptoms of toxicity or hypervitaminosis (excess of vitamin A) can be:
Anorexia, weight loss, vomiting and nausea, blurred vision, irritability, hepatomegaly, alopecia, headaches, insomnia, weakness, poor muscle strength amenorrhea (cessation of menstrual period), hydrocephalus and cranial hypertension in children. Read the rest of this entry »
The Main Sources of Vitamin A
The main sources of vitamin A are:
In the animal kingdom: dairy products, egg yolks and fish liver oil.
In plants: All plants yellow to red, or dark greens, carrots, sweet potatoes, pumpkins, squash, peppers, spinach, radicchio, lettuce, broccoli, Brussels sprouts, tomatoes, asparagus
In fruit: Damascus, peach, melon, papaya, mango, papaya
Consequences of lack or deficiency of vitamin A
Lack of vitamin A enters brings several consequences which are:
* Eye disorders: Twilight may cause blindness, ie visual acuity decreases at night, extreme sensitivity to light as well as dryness, opacity of the cornea ulcers, called xerophthalmia, which can lead to blindness
* Low immunity (low defenses) increases susceptibility to bacterial, parasitic or viral infections and vitamin A contributes to the maintenance of mucosal integrity. Lacking she disappears barrier against infections. Immune system cells are also affected which may lead to an increase in pre-cancerous cells of epithelial tissues of the mouth, throat and lungs.

Vitamin A Benefit for The Body
Brief definition
Belongs to a group of fat soluble vitamins (soluble in fat) is essential for the body.
This vitamin is present in foods of animal origin as a pre-formed vitamin A and retinol is called while the plant appears as provitamin A, also known as carotenoids (or carotenoids) among which stands out the beta carotene.
Beta carotene are natural pigments that are found in fruits and vegetables red, orange and yellow, or in dark green vegetables. Beta-carotene is a chemical form required by the body for the formation of vitamin-A.
Approximately 80 to 90% of the esters of retinol absorbed while beta carotene do between 40 to 60%. The majority of vitamin A, almost 90% is stored in the liver, the remainder being deposited in the lungs, kidneys and body fat.
Functions of Vitamin A and retinol in the body:
* Skeletal system: it is necessary for growth and bone development.
* Cell development: essential for growth, maintenance and repair of mucosal cells, epithelium, skin, vision, nails, hair and tooth enamel. Read the rest of this entry »
Potassium to Combat Hypertension
Hypertension is a very common disease worldwide that is characterized by increased blood pressure repeatedly and can bring many consequences and can even cause death. That is why doctors recommend taking care of blood pressure since we are young to not suffer unpleasant consequences.
There are many ways to prevent hypertension, the first step is to reduce the amount of sodium that is ingested and therefore should not add salt to your food and avoid consuming canned foods, concentrates or sausages, as they have high amounts of sodium . In addition, we must consume plenty of water and exercise daily to oxygenate the blood.
Recently, it was also found that potassium is a very effective in controlling blood pressure stable, reducing pressure and fluid removed.
Dosage and Toxicity of Biotin
The National Research Council states that are needed from 150 to 300 micrograms of biotin (RDA) for daily body’s needs. During pregnancy and lactation is necessary to increase the dose. There are no known toxic effects of this nutrient.
The daily requirement of biotin can be covered with drinking:
* 1 whole cooked egg, 1 small portion of beef (100-150 g)
* 1 large vegetable salad (150 grams in total) and 1 small piece of chicken (150 grams)
* 1 large portion of fish selection (250 g) and a large fruit (200-250 g)
* 1 large serving of beef (250 grams)
* 1 small serving of beef liver (80-100 g)
Deficiency and symptoms
Only deficiency states have been reported when consumed a diet with large amounts of raw egg white and when taken many antibiotics. The latter interfere with the production of biotin by the intestinal flora bacteria.
Biotin
Biotin is a water soluble vitamin B group In his role as a coenzyme (a molecule essential for the enzyme to perform its biological function) assists in the synthesis of fatty acids and oxidation reactions and carbohydrates, no fat biotin production is reduced.
On the other hand, biotin help using protein, folic acid, pantothenic acid and vitamin B12.
The vitamin biotin is an essential nutrient that appears in small amounts in all plant and animal tissues.
Sources of Biotin
Some rich sources of biotin are egg yolk, liver, grilled, rice, cauliflower, mushrooms, peas, brewer’s yeast, peanuts, mackerel and sardines.
