Follow-up on folate and cancer risk

We’ve had a recent comment on our own post regarding the importance of B12 and folate supplementation for people with HIV. The comment expressed concern about some reports that folate may be associated with increased cancer risk. Here’s a reply to that comment:

We recommend this web page for a recent study of folate and REDUCED colorectal cancer risk:

The 2011 article cited, by a well-known nutrition scientist, finds folate from diet and folate from supplements both associated with reduced colorectal cancer incidence–when taken over a long period (we’re talking about 15-20-30 years). This fits with what is generally understood about the value of vegetables in reducing cancer risk. Not surprising to us is the other finding of the study: that short-term folate intake, around the time of the development of pre-cancers, is not going to help reduce cancer incidence! Indeed, many supplements do not necessarily produce pronounced short-term effects, but rather show health benefits over the long term.
