While earlier research studies and laboratory analysis suggested potion pills as an effective tool to combat worst diseases like cancerdefine, heart disease and stroke, the latest study debunks all closely held beliefs.
The results are based on a close assessment of over 7,600 well-nourished women, averaging 60 years at the start of study. All women either had a cardiovascular disease or were at a high risk for it.
For almost a decade, volunteers were randomly put on a daily does of 500 milligrams of vitamin C, or an alternate day dose of 600 IU of vitamin E or 50 milligrams of beta carotene. A few were put on placebo supplements.
During follow-up period, a similar number of cancer diagnoses and deaths occurred among women on supplements and placebos, signifying the absence of statistical evidence that the supplements helped or hindered the volunteer's risk of cancer.
However, vitamin E supplements helped reduce the risk of colon
define cancer, while beta carotene supplements reasonably raised the risk of cancer risk, researchers highlighted.
Getting deeper into analysis to see why earlier researches touted supplements as antidotes for cancers, study’s lead author Jennifer Lin, an assistant professor of medicine at Harvard Medical School, found supplements comparatively effective in poorly nourished women, but not in well-nourished women as is the case in the current study.
Underlining the importance of a healthy diet, Dr. JoAnn Manson of Brigham and Women's Hospital and Harvard Medical School in Boston stated, "Although a healthful dietary pattern rich in fruits and vegetables may lower cancer risk, such benefits cannot be mimicked by simply popping a few vitamin supplements."
"Supplements are just one tool that people need to incorporate into their lifestyle to stay healthy. We can't expect just to take supplements and that's going to prevent cancer. That simply isn't the way it works," Andrew Shao, vice president of Council for Responsible Nutrition, a dietary supplement industry group, marked.
