Always been a salad eater, but suddenly that pile of leafy greens is as unappetizing as chopped liver? Many women describe strong reactions -- good and bad -- to food during early pregnancy.

This means focusing on food that is high in fiber, folic acid, calcium, iron, vitamins C and A, and also taking a daily prenatal vitamin supplement. After all, it's never too early to teach your child healthy eating habits.
