Vitamin A was given the first letter of the alphabet for a name because it was the first vitamin 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 and meat. Beta carotene that the body can convert into vitamin A is found 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 persons 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 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 from the high levels of beta carotene that are found in the vegetables. Other foods which have high levels of beta carotene that can be converted to vitamin A include tomatoes and dark green leafy vegetables, such as spinach. Beta 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 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 various parts of the body, 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.

The e vitamin is extremely important for a variety of functions in the body. A healthy heart needs plenty of the e vitamin as it has been shown to actually prevent heart disease. The e vitamin can also help contain any existing heart disease and stop it from getting worse.

E vitamin is also vital in protecting the cell membranes from the harmful free radicals that are present in the body. Without e vitamin, amongst others, the cell membranes would be damaged and this could lead to serious health problems, including cancer. The reason that the e vitamin is so effective against free radicals is that it is fat soluble so it can be absorbed into the cell membranes. The e vitamin is therefore essential for the immune system.

The recommended daily amount of the e vitamin that a person requires depends on their body weight. This is connected to the fact that the more fat a diet contains then the more of the e vitamin that is needed. However, the only foods that really contain any reasonable amount of the e vitamin are vegetable oils, seeds, wheat germ, and nuts. It is for this reason that most people should take some form of e vitamin supplement.

A deficiency of the e vitamin does not affect a person immediately. In fact, it can take months for the effects of insufficient e vitamin to be detected. After years of e vitamin deficiency there may e some detectable damage to the nerves of the spinal cord or retina of the eye but this is very rare. Most people obtain enough e vitamin from a normal diet but it is essential that the food that a person eats contains a little fat to help with the absorption of the e vitamin.

There are a few medical conditions that may lead to a deficiency of the e vitamin and may require the person to take e vitamin supplements. Cystic fibrosis causes a person to be unable to digest fats well which leads to less of the e vitamin being absorbed. Crohns disease causes to lower absorption rates of the e vitamin and a supplement may be necessary. Some forms of liver disease can also lead to problems absorbing the e vitamin, especially through the intestine. Of course, as fat is required to help absorb sufficient amounts of the e vitamin, anyone on an extremely low-fat diet will need to discuss their options for increasing the amount of e vitamin that their body needs.
