Beta-carotene and tobacco

Recent studies have shown that smoking and taking beta-carotene supplements do not go together. Beta-carotene is an antioxidant, which means that deactivates free radicals in the body. In the process, it oxidizes and can become a kind of pro-oxidant or form oxidized by-products. Normally, we do not have to worry about the byproducts of an anti-oxidant beta-carotene. If you maintain a healthy diet with a variety of antioxidants they will work together to protect each other from oxidation.

It seems that smokers of both have something to fear. Two studies ending in the nineties found that people who smoked at least a pack a day or drank higher than average amounts of alcohol and took beta-carotene or vitamin A supplements have been a higher risk of developing lung cancer and a higher risk of dying. Each of these trials have shown that beta-carotene is not helping many of its participants and smoking was in fact harm some of them. The first essay The Tocopheral Alpha, Beta-Carotene Cancer Prevention Trial showed lung cancer Eighteen percent of over eight percent more deaths among male smokers who took 20 mg beta-carotene. The second trial, called beta-carotene and retinol efficacy trial (caret) Initial results showed that there were twenty eight percent of lung cancer over the group of smokers and former smokers that She had taken beta-carotene and vitamin A and seventeen percent more deaths. These results were so similar to results from Cancer Prevention Trial final which they told the participants to stop taking the supplements before the trial was ended.

Why? Well, since it is thought that anti-oxidants protect each Oxidation Scientists suspect that smokers do not get enough of other types of antioxidant vitamins in their systems to prevent that happening. It was found that smokers have low levels of vitamin C in their blood stream and is "one of the antioxidants. Thus, beta-carotene is oxidized in the body after it uses its antioxidant effect in one becomes a damaging free radicals or exacerbate damage to lung cells of smokers, which leads to abnormal cell growth and cancer . With low levels of other types of antioxidants in the body there is nothing to stop it. Scientists believe that the two antioxidants that work together to protect the body against oxidative damage Beta Carotene Pro are vitamins E and C.

If you are a smoker, you should make any attempt to avoid or beta-carotene into vitamin A in your diet. These tests suggest that all anti-oxidants work together to prevent cancer and to isolate one or the other for consumption, especially in a non-natural, simply negates its effects and sometimes cause problems. What you need to do is focusing on eating plenty of foods containing antioxidants in combination. There is no evidence that suggests that current eating foods with beta-carotene may increase the risk of cancer among smokers.
