Healthy food choices like fruits, vegetables, whole-grain breads and pastas, non-fat or low-fat milk products, and low-fat protein sources, such as lean red meat, poultry without the skin and beans will help your body do a good job of keeping both you and your baby healthy. You should also take a prenatal vitamin that contains folic acid every day. Talk to your doctor about how much folic acid to take and how to ensure your diet meets the nutritional needs of pregnancy.
