Clipping Board » Drug Poisoning ─ It is necessary to be aware of the toxic side effects before taking medication.
2012/10/16 [Taiwan New Life News / Reporter Chen Jingzhe / Comprehensive Foreign Reports]
A recent U.S. study found that consuming more folate and vitamin B does not prevent the growth of colon polyps and, consequently, cannot further reduce the risk of colorectal cancer. This contradicts previous U.S. medical research suggesting that higher vitamin intake might lower the risk of colorectal cancer. Medical researcher John stated that, based on this data, increasing folate-rich food intake to raise folate levels in the body provides no overall benefit in terms of preventing colorectal cancer.
Song Qingyi (phonetic) from Boston Women's Hospital in the U.S. published the study results in the journal of the National Cancer Institute. The study involved 1,470 women with an average age of 62, divided into two groups. One group took daily doses of folate, vitamin B6, and B12, while the other received a placebo. The findings showed that the incidence of colon polyps was 24% in the folate and vitamin group and 24.3% in the placebo group, indicating almost no difference.
John also emphasized that folate ensures proper DNA replication during cell division, theoretically reducing cancer risk. However, it is also necessary to consider the opposite scenario: for patients who already have polyps, folate might promote their growth. He further stressed that, beyond a normal diet, additional vitamin B intake in this study provided no protective health benefits. Generally, most Americans already consume sufficient nutrients through their regular diet, and excessive folate intake only leads to waste without substantial benefits.
