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 to ensure all of your diet meets the nutritional needs of pregnancy.
