    ### Response:
    Summary : When you're pregnant, eating healthy foods is more important than ever. You need more protein, iron, calcium, and folic acid than you did before pregnancy. You also need more calories. But "eating for two" doesn't mean eating twice as much. It means that the foods you eat are the main source of nutrients for your baby.
