Antioxidants showed no " statistically significant effects " on cancer

incidence,according to an analysis of earlier research published in

the Jan. 7 Journal of the National Cancer Institute.

Lin and colleagues from Brigham and Women's Hospital and

Harvard Medical School re-examined data from the Women's Antioxidant

Cardiovascular Study for their report, " Vitamins C and E and Beta

Carotene Supplementation and Cancer Risk: A Randomized Controlled Trial. "

Starting in 1995, WACS followed 8,171 women at high risk for

cardiovascular disease for an average of 9.4 years.

Lin's group studied the 7,600 women who were cancer-free before

assignment.

The double-blind placebo-controlled trial randomized participants to

placebo or 500 mg vitamin C daily, 600 IU naturally sourced vitamin E

and 50 mg of beta carotene every other day.

Results were collected via annual compliance questionnaires. After 9.4

years, 624 of the women developed invasive cancer and 176 women died

from cancer, Lin and colleagues note.

The authors say their results are in line with other research on

antioxidants and cancer reduction.

" Findings from the WACS trial suggest that there are no overall

benefits or risks of vitamins C and E and beta carotene supplementation

in the primary prevention of total cancer incidence or mortality. "

The authors note factors that could affect the efficacy of

antioxidants include the formulation, trial duration and lifestyle

behaviors.

Limits include lack of follow-up and compliance. Also the CVD risk

group may not represent the general population, the authors allow.

In an accompanying editorial, the National Cancer Institute's

Demetrius Albanes wrote that the trial should not be considered a

failure.

He pointed out the study found vitamin E supplementation possibly

prevents colorectal cancer.

" Null trials ... have and will continue to shed light on the causes of

cancer and help us discover the means for its prevention. "

Here again a 'study' shows no significant benefit from the use of antioxidants

as often shown for other supplements.

Studies are almost meaningless because of how they are conducted such as the

amounts a particular substance and frequency of its use.

Do many people on this list give much credence to tests and studies performed by

The Establishment knowing, as most of us do, that the system is biased against

anything other than their own treatments?

It wasn't long ago that High Dose IV Vitamin C was given a good report during

some tests, however, I'll wager that it isn't easy finding many Medical

Professionals using it.

Then we have the Grape Seed information just given us and I imagine many will be

rushing out to buy some. After reading the report on it one quickly realizes

the subject's real importance has to do with its 'delivery to the cancerous

cells' which probably doesn't happen when we swallow a couple. I happen to

use Grape Seed because it seems to have proven itself to my wife and me when

symptoms of a cold first appear. It is good stuff.

I posted awhile back the absurd meta-study where they cherry picked a

very small subset of studies that supported a pre-arrived conclusion

regarding supplements. Just absurd.
