Vitamin A and beta-carotene


Recommended Posts

  • Administrator

If you have had diarrhea or been unable to eat properly for a long time, you may be low in vitamin A.

 

From Medscape http://emedicine.medscape.com/article/126004-overview

Vitamin A is essential for vision (especially dark adaptation), immune response, bone growth, reproduction, the maintenance of the surface linings of the eyes, epithelial cell growth and repair, and the epithelial integrity of the respiratory, urinary, and intestinal tracts. Vitamin A is also important for embryonic development and the regulation of adult genes. It functions as an activator of gene expression by retinoid alpha-receptor transcription factor and ligand-dependent transcription factor.

 

....Abnormal visual adaptation to darkness, dry skin, dry hair, broken fingernails, and decreased resistance to infections are among the first signs of vitamin A deficiency (VAD)....

Vitamin A is found in red and orange vegetables, such as pumpkin, squash, and carrots, where it appears as a substance called beta-carotene.

 

Food beta-carotene is probably a more effective and safer way to boost vitamin A than taking synthetic vitamin A supplements. Beta-carotene is a provitamin A: Your body can convert what it needs to vitamin A. Plus, food betacarotene contains a bunch of other associated nutrients.

Provitamin A carotenoids such as beta-carotene are generally considered safe because they are not associated with specific adverse health effects. Their conversion to vitamin A decreases when body stores are full. A high intake of provitamin A carotenoids can turn the skin yellow, but this is not considered dangerous to health.

Note all the foods containing vitamin A, including liver.

 

Soups made from pumpkin, squash, or carrots are very easy to make, and even taste good cold. All you need to do is: - Cut the raw veg into chunks

- Steam, roast, or microwave it until it's cooked

- Add flavorings, if you wish, such as cinnamon or ginger, thyme, salt and pepper

- Put all in a food processor with a little milk, chicken broth, vegetable broth, or water, or use a stick blender to puree until smooth. (I love my stick blender, it's easy to clean.)

- Eat at room temperature or heat up for hot soup

 

There are beta-carotene supplements derived from food. I took Natural Factors BetaCareAll food beta-carotene supplement for a few months because I thought it would be good for my gut (repairs mucus membranes). I don't know if it helped, but my gut did get better.

>45% of all people of western origin does not convert or convert very little of beta carotene to vitamin a (retinol) due to genetics. This makes beta carotene a poor supplement for us. Retinol is the proper form for supplementation, and like vitamin d, can be taken on and of as our body can stores retinol for later use. Liver is a good source of vitamin A. Maybe this is one of the reasons why so many feel awful when on a vegetarian diet? (
