Folate and Colon Cancer Risk



Here's more good news about diet and cancer: a, recent large study shows that people whose diets included the most folate were 30 percent less likely to develop colon cancer than were those whose intake of this nutrient was low. Researchers from the National Cancer Institute looked at data from diet surveys that reflect the effects of fortification of food with folic acid (a synthetic form of folate) instituted in the late 1990s.

They found the lowest risk of colon cancer among individuals whose folate intake was highest (at least 900 micrograms per day) compared to those who got less than 200 mcg daily. The investigators were also looking for links between high levels of folate and higher risks of colon cancer, but found no evidence of a connection. However, this study couldn't rule out the possibility that those who get too much folate through the combination of supplements and fortified foods might be at increased risk for colon cancer, as some other studies have suggested. The findings were published online on August 3 by the American Journal of Nutrition.
