Most of us recognize vitamin A as one of the fat-soluble vitamins. We’ve been told that vitamin A can be beneficial to our eyes and help us to see better for a much longer span of time. That is true of vitamin A, but the vitamin also holds many other benefits that you may not have realized. 

About Vitamin A
 
Vitamin A is an antioxidant. It may actually help to prevent some types of cancer. Cellular oxidation takes place in the body. Certain foods which contain vitamin A, as well as other vitamins can help to prevent that oxidation from taking place and remove free radicals from the body. Vitamin A can also help to stall the growth of some types of cancerous cells, as well as to prevent them from taking hold in the body. 

 
Supplementation and Toxic Levels 
Vitamin A supplements can cause a toxic effect in the body. This is true because, as a fat soluble vitamin, Vitamin Amay build up in the body and be stored in fatty tissue. That is typically not true of vitamin A which is taken from your food. This means that obtaining your vitamin A from your food is a much safer and usually much healthier method of obtaining the vitamin. Most orange and yellow vegetables contain carotene. Carotene is a precursor of vitamin A, which means that the carotene in your food is only converted to vitamin A if the body requires that it be so. 

Low Vitamin A or Toxic Levels of Vitamin A. 

In most cases, toxicity of vitamin A may be responsible for hair loss, for sore muscles and joints, while low vitamin A in the body can be responsible for weakened muscles, weakened immune system, and far more frequent infections as well as infections which will be slower to heal. Lower levels of vitamin A may also cause some vision problems.Vitamin A toxicity is relatively rare today since most people obtain all that they require from their food. Only those who are hyper-vitaminizing are typically found to have toxic levels of vitamin A. 

Health Benefits of Vitamin A
 
Among the health benefits that the body gets from vitamin A are the prevention of infection, reparation of the skin, the throat, the eyes and the digestive tract. This is another reason why vitamin A may prevent cancer. Vitamin A may also help to boost your immune system, as well as to assist the lymphocytic system in functioning and growing stronger. 

In addition, vitamin A may also be helpful in preventing the vision problems as well as cataracts with advanced age. 

Foods Which Contain Vitamin A

Foods from which you may obtain vitamin A include yams, sweet potatoes, carrots, liver, chili powder, paprika, spinach, winter squash, lettuce and apricots.
