Folate Deficiency May Increase Your Cancer Risk.
Diets rich in folate and folic acid are linked to a decreased risk of certain types of cancer. Populations that get sufficient folate in their diet have lower rates of breast, cervical, colon, pancreatic, and stomach cancer. On the other hand, folate deficiency increases the risk of these cancers. One study found that cancer patients had a much higher rate of folate deficiency than noncancer patients. Researchers don’t know exactly how the nutrient protects against cancer. One theory is that because cancers are caused by DNA mutations that make cells behave abnormally and folate helps keep DNA healthy, the nutrient may protect DNA from cancer-causing mutations.
