If you're like over three-quarters of American women, you probably weren't eating enough fruits and vegetables before your pregnancy. And odds are that you also weren't getting enough magnesium, and vitamins E, A, and C. Pregnancy provides the perfect opportunity to evaluate and reinvent your dietary habits. Unfortunately, morning sickness, heartburn, and other pregnancy discomforts can sabotage your best intentions. Don't be discouraged. Open your mind and palate to new nutrient-rich foods and be flexible with the size and frequency of your meals.
