All About Vitamin A
Vitamin A was given the first letter of the alphabet for a name because [url=http://www.1855sacramento.com/peuterey.php]peuterey outlet[/url] it was the first vitamin [url=http://www.1855sacramento.com/moncler.php]moncler sito ufficiale[/url] to be discovered. It was found that vitamin A has a large number of uses in the body including keeping eyes healthy, aiding cell growth and also helping boost the immune system. However, vitamin A is not only absorbed directly but it is also created by the body by converting beta carotene into vitamin A.
Vitamin A itself is found in a number of foods such as eggs, milk, liver [url=http://www.davidhabchy.com]barbour outlet[/url] and meat. Beta carotene that the body can convert into vitamin A is found [url=http://www.mansmanifesto.fr/category/doudoune-moncler/]doudoune moncler[/url] in many fruits and vegetables, especially the red, orange and green coloured ones. The most important point to remember that consuming too much pure vitamin A can be toxic. It is essential not to exceed the recommended daily allowance for vitamin A. The actual recommended allowance of vitamin A varies depending on a person’s age, sex and other factors. While the actual amount of vitamin A consumed may be toxic if the recommended daily allowance is exceeded, there is a far higher limit to how much beta carotene can be consumed. Therefore it is advisable to concentrate on obtaining the greatest amount of beta carotene which the body can then [url=http://www.maximoupgrade.com/hot.php]hollister france[/url] convert to vitamin A, rather than consuming vast quantities of pure vitamin A rich foods.
Many people will remember being told that eating lots of carrots helps you to see in the dark and that is down to the vitamin A that is produced [url=http://www.achbanker.com/home.php]hollister france[/url] from the high levels of beta carotene that are found in the vegetables. Other foods which have high levels of beta carotene that can [url=http://www.davidhabchy.com]barbour sale[/url] be converted to vitamin A include tomatoes and dark [url=http://www.vivid-host.com/barbour.htm]www.vivid-host.com/barbour.htm[/url] green leafy vegetables, such as spinach. Beta [url=http://www.thehygienerevolution.com/barbour.php]barbour paris[/url] carotene is not only used to form vitamin A, but it is also a powerful antioxidant in itself. None of the beta carotene that is absorbed is wasted as any excess after conversion to vitamin [url=http://www.hollisterhanesmorgan.co.uk]hollister uk[/url] A has taken place is used to fight the harmful free radicals within the body. Vitamin A also helps fight infections and illnesses by helping tissues that line [url=http://www.mquin.com/giuseppezanotti.php]giuseppe zanotti pas cher[/url] various parts of the body, [url=http://www.mxitcms.com/tiffany/]tiffany[/url] including the eyes, mouth, nose, throat and lungs, to grow and also to repair them if they are damaged to prevent infection. Children also need plenty of vitamin A to help their bones and teeth to develop properly.
