Beta Carotene and Smoking

By: hari

Recent studies have shown that smoking and taking Beta Carotene supplements do

not go together. Beta Carotene is an antioxidant, which means that it

inactivates 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 don't have to

worry about the by-products of Beta Carotene's antioxidant behavior. If you

maintain a healthy diet with a variety of antioxidants they will work in

combination to protect one another from oxidizing.

It appears that smokers on the other hand do have something to worry about. Two

studies ending in the nineties found that people who smoked at least one pack a

day or drank higher than average amounts of alcohol and took Beta Carotene or

Vitamin A supplements were at a higher risk for developing lung cancer and a

higher risk of dying. Each of these trials showed that Beta Carotene wasn't

helping many of its smoking participants and was in fact hurting some of them.

The first trial called The Alpha-Tocopheral, Beta Carotene Cancer Prevention

Trial showed eighteen percent more lung cancer and eight percent more deaths in

male smokers who took 20mg of Beta Carotene. The second trial called the Beta

Carotene and Retinol Efficacy Trial (CARET) initial results showed that there

was twenty eight percent more lung cancer in the group of smokers and former

smokers it had taking Beta Carotene and Vitamin A and seventeen percent more

deaths. These results were so similar to the Cancer Prevention Trial final

results that they told the participants to stop taking the supplements before

the trial was scheduled to end.

Why is this so? Well, since it's thought that anti-oxidants protect each other

from oxidizing scientists suspect that smokers don't have enough of the other

types of antioxidant vitamins in their systems to prevent this from occurring.

It has been found that smokers have low levels of Vitamin C in their blood

stream-and that's' one of the antioxidants. So the Beta Carotene oxidizes in

the body after it uses up its antioxidant properties an in effect becomes a free

radical damaging or exacerbating damage done to the cells of smokers lungs which

leads to abnormal cell growth and cancer. With low levels of other kinds of

antioxidants in their bodies there's nothing to stop it. Scientists believe

that the two antioxidants that work together to protect the body from Beta

Carotene pro oxidant damage are Vitamins E and C.

If you are a smoker you should by no means try to avoid Beta Carotene or Vitamin

A in your diet. These trials seem to show that all anti-oxidants work together

to prevent cancer and isolating one or the other for consumption, especially in

a non-natural form, simply negates its effects and sometimes causes problems.

What you should be doing is focusing on eating a lot of foods with antioxidants

in combination. There is no evidence as of current that suggests eating foods

with Beta Carotene in them can increase the risk of cancer in smokers.
