Folic acid supplements may raise cancer risk: study

Now it's bad.

"Heart patients in Norway -- where unlike many countries foods are not enriched with folic acid -- were more likely to die from cancer if they took folic acid and vitamin B12 supplements compared with those who did not take them, Norwegian researchers said on Tuesday.

The team found lung cancer rates were 25 percent higher among those who took the supplements compared with the general population, but overall cancer deaths and deaths from other causes were also higher in the supplement group.

They said folic acid given over a period of more than three years may feed the growth of cancers that were too small to be detected otherwise, and raises new questions about the benefits of fortifying foods with folic acid."

Still think they have any idea what they are talking about?
