Colon Cancer & B Vitamins

A mouse study published in the December 2007 issue of the Journal of Nutrition suggests a B vitamin deficiency increases the risk of DNA damage and colorectal cancers.

A number of studies have linked folate deficiency to colon cancer. However, many biochemical functions of folate are dependent on adequate availability of other B vitamins, including B6, B12 and riboflavin.

The researchers in the new Journal of Nutrition study suggested that a mild depletion of folate alone did not affect DNA, but a mild depletion of all four B vitamins significantly increased the DNA damage on the tumor suppressor gene, adenomatosis polyposis coli gene (Apc).

We can't stress enough the importance of supplementing with a full-spectrum multiple that includes all of the B complex vitamins.

Here is my question:

How many more studies like this will have to be funded to make doctors stop telling their patients that they get all the vitamins they need from the foods they eat?

Since woman have to take more folic acid when they are pregnant, breastfeeding and trying to conceive are they less likely to develop colon cancer?
