Recent research indicates that even years of supplementation with nutrients such as Beta Carotene, Vitamin C, and E cannot reduce the overall risk of cancer. This study casts doubt on the possibility of such nutritional supplements preventing cancer.
Published today in the "Journal of the National Cancer Institute," this research followed 7,627 women, who were on average over 60 years old at the start of the study and took vitamin supplements for about nine and a half years. Some of these women took 500 mg of Vitamin C daily, 600 International Units (IU) of Vitamin E every other day, or 50 mg of Beta Carotene, or a combination of these three vitamin supplements, while another group took a placebo. The results showed similar cancer rates and mortality rates between those who took vitamin supplements and those who did not.
Dr. JoAnn Manson from Brigham and Women's Hospital in Boston and Harvard Medical School stated in the report: "Although a healthy diet rich in fruits and vegetables may reduce the risk of cancer, the same benefits cannot be achieved simply by taking a few vitamin pills."

Be careful not to take them in vain! The myth of taking a daily vitamin supplement seems to be gradually debunked.
Vitamin E and C supplements, commonly used by many women and middle-aged and elderly people for health maintenance, have been found not only ineffective in preventing cardiovascular diseases but also, according to the latest research, seem to be equally ineffective in preventing cancer.
A significant number of people worldwide take vitamin supplements daily hoping to prevent chronic diseases. However, there has never been a rigorous long-term randomized study to test the preventive effects of these vitamin supplements. Recently, at the Seventh International Annual Meeting of the American Association for Cancer Research held in Maryland, USA, a research team from Brigham and Women's Hospital in Boston presented a study that provided some answers. Due to its rare large-scale follow-up, the results have garnered widespread attention.
The study database comes from the Physicians' Health Study II, involving 14,500 male physicians aged 50 and above. Participants were randomly divided into two groups: one group took vitamin E or C, and the other took a placebo, without knowing which they were taking. The study, tracked since 1997, showed that vitamin E and C had no effect in preventing various types of cancer.
"After nearly 10 years of follow-up research, there is no evidence to support that taking vitamin E or C supplements helps prevent cancer," said Howard D. Sesso, an associate professor at Brigham and Women's Hospital in Boston. Although these two supplements showed no benefits, they also did not cause harm.
Some past studies suggested that consuming foods rich in vitamins E and C could reduce the risk of cancer, but this study confirms that natural dietary intake and taking vitamin supplements are two different things. Co-researcher Gaziano stated that vitamin supplements cannot provide the health benefits of a balanced natural diet.
Sesso mentioned that this finding is quite significant because there have been very few studies like this to test the efficacy of vitamins, and research on the health benefits of multivitamin supplements is still ongoing.
In fact, a paper stating that vitamin E and C supplements are ineffective in preventing cardiovascular diseases was recently published in the prestigious Journal of the American Medical Association (JAMA).
