The latest U.S. study shows that consuming more folic acid and vitamin B does not prevent the growth of colon polyps, and thus cannot further prevent the occurrence of colorectal cancer. This contradicts previous U.S. medical research, which suggested that higher vitamin intake might reduce the risk of colorectal cancer. Medical researcher John stated that, according to the data from this study, increasing folic acid intake through foods rich in folate provides no overall benefits in terms of preventing colorectal cancer.
Song Qingyi (transliteration) 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 a daily dose of folic acid and vitamins B6 and B12, while the other group received a placebo. The results showed that the incidence of colorectal polyps was 24% in the group taking folic acid and vitamins, compared to 24.3% in the placebo group—virtually no difference.
John also emphasized that while folic acid ensures proper DNA replication during cell division and theoretically could reduce cancer risk, it is also necessary to consider the opposite effect: in patients who already have polyps, folic acid might promote their growth. He further stressed that, beyond a normal diet, the study found no protective effect from additional vitamin B intake. Generally, most Americans already receive adequate nutrition, and the folic acid obtained from a regular diet is sufficient. Excessive folic acid intake only leads to waste without any real benefits.
