A well-rounded diet that is high in protein, vitamins, and minerals is needed to support your body and prepare it for a growing baby. Eat a hearty breakfast each day; as to include bran and fruit, and throughout the day, Green leafies (like Kale), and beans and rice that offer essential amino acids are all important.
Eat as naturally as possible. Lots of fresh fruit and vegetables, good quality protein like lean meat or chicken and whole grains are the best. Approach a nutritionist or look online as some foods should be avoided while pregnant, like shellfish. Avoid alcohol and caffeine and give up smoking. Drink filtered water. Get plenty of exercise in the fresh air and learn to relax with meditation, for example. You will need to learn to relax your body and mind even when you are over-tired when you have a baby.
