Your diet will undergo a major change during pregnancy.What makes for a good pregnancy diet?
Congratulations! You are pregnant and now you must start “eating for two.” That means an extra 300 calories a day. Of course it varies from mom to mom, but an expectant mother can gain about 30 pounds during pregnancy. However, don’t worry about monitoring your bathroom scale. Instead focus on eating a variety of healthy foods that will ensure you and your baby are getting the nutrition you both need. For good nutrition during pregnancy, The Mayo Clinic recommends selecting from these food sources, daily: grains, fruits and vegetables, meat, fish, eggs, poultry, beans, and dairy.
Six to 8 ounces of whole grains each day will ensure your baby is receiving enough folic acid. According to the March of Dimes, folic acid is an important nutrient that can help prevent spinal cord birth defects.
