It is obviously important at all times to eat nutritious and balanced meals. However it is even more essential to eat the right food and not eat the wrong food when trying to conceive and during pregnancy. You and your baby require essential nutrients, protein, fats, carbohydrates, vitamins, and minerals to ensure a healthier pregnancy. Most foods are safe; however, there are some foods that you should avoid during pregnancy. These specifically include potentially infectious foods (listeria, hepatitis B, toxoplasma), and food that contain too much mercury or other harmful agents.
