Good nutrition is important throughout your entire pregnancy. Each day, aim for at least four servings of dairy, three servings of protein, six to 11 servings of grains, two to four servings of fruit and four or more servings of vegetables. By sticking to a balanced diet, you’ll take in nutrients that will nourish baby. For instance, iodine (in dairy and baked potatoes) will help support the development of their nervous system and folate (in dark green leafy veggies and legumes) will help prevent neural tube defects like spina bifida. Ask your doctor whether you should take a prenatal vitamin and folic acid supplement.
