Some molecules found in foods are known to be capable ofdriving DNA methylation or DNA demethylation. For example,folic acid (a vitamin), vitamin B12, and choline are thought toincrease methylation. Based on this consideration, why wouldit be important to avoid eating excessive quantities of suchmolecules (while being certain to eat sufficient quantities forhealth)?
