Antioxidants And Cancer. Study

It is widely believed , and recommended by Doctors , that anti oxidants prevent formation of cancerous Cells.

As Fruits and vegetables contain Anti Oxidants‘ consuming them is recommended to ward off Cancer.

Now it is proved to be incorrect.

cancer and Antioxidants.
Anti oxidants And Cancer.

As in Smoking where it is said that Smoking Causes Cancer,the reason being that higher percentage of people who have Cancer were found be Smokers,

In the same vein,” Some studies have shown that people who eat more fruits and vegetables have a lower incidence of cancer and heart disease and live longer. The logic is obvious. If fruits and vegetables contain antioxidants, and people who eat fruits and vegetables are healthier, then people who take supplemental antioxidants should also be healthier.”

The Logic is faulty in both the cases.

My wife wears a Green Saree.

It does not mean who ever wears a Green Saree is my wife!

Science often jumps the Gun by touting incomplete data as Conclusive and we blindly follow it!

 It hasn’t worked out that way.

The likely explanation is that free radicals aren’t as evil as advertised. (In fact, people need them to kill bacteria and eliminate new cancer cells.) And when people take large doses of antioxidants in the form of supplemental vitamins, the balance between free radical production and destruction might tip too much in one direction, causing an unnatural state where the immune system is less able to kill harmful invaders. Researchers call this the antioxidant paradox.


  1. Can antioxidants prevent cancer?

    Considerable laboratory evidence from chemical, cell culture, and animal studies indicates that antioxidants may slow or possibly prevent the development of cancer. However, information from recent clinical trials is less clear. In recent years, large-scale, randomized clinical trials reached inconsistent conclusions.

  2. What was shown in previously published large-scale clinical trials?

    Five large-scale clinical trials published in the 1990s reached differing conclusions about the effect of antioxidants on cancer. The studies examined the effect of beta-carotene and other antioxidants on cancer in different patient groups. However, beta-carotene appeared to have different effects depending upon the patient population. The conclusions of each study are summarized below.
