Loading up on folic acid before and during pregnancy (suggested dosage is at least 800 micrograms) will protect your baby from serious birth defects of the spinal cord (spina bifida) and the brain (anencephaly).  All the while regulating the cellular replication that is literally creating your baby and propping them up with some great DNA.

Take a quality supplement and load up on folate rich foods: beans and lentils, peas (black-eyed peas, chickpeas, green peas), juices (orange, tomato, grapefruit, pineapple), fruits (oranges, cantaloupe, honeydew melon, avocado, papaya, raspberries), soymilk, vegetables (green leafy vegetables such as spinach, lettuce, turnip greens, mustard greens, collard greens, and Chinese cabbage; broccoli; Brussels sprouts; asparagus; artichokes; okra; corn; cauliflower; potato; beets; green onions; sweet red peppers), nuts and sunflower seeds.
