1. The U.S. Public Health Service recommends that all women who could become pregnant get 400 micrograms (0.4 mg) of the B-vitamin folic acid every day. This could prevent up to 70 percent of some types of serious birth defects. But to do this, women need to be getting the folic acid over a month before they get pregnant and through the first few weeks the baby is growing. Ask your doctor about folic acid and whether or not you need supplements.
2. During pregnancy, your body needs more nutrients to provide a baby with what it needs. But that doesn't mean you should double the amount of food you eat. According to the National Women's Health Information Center, most pregnant women need to consume an extra 300 calories a day. Again, talk with your doctor.
3. In order to decrease the risk of delivering a low birth-weight baby, it's important for pregnant women to gain enough weight. The National Institutes of Health say total weight gain for most women should be about 25-30 pounds during the pregnancy. Talk with your doctor for information on how much weight you should expect to gain.
