Adoption by women of dietary practices that are based on Dietary Guidelines for Americans (8) can promote improved general and reproductive health and can help prevent chronic disease. Additional guidance is indicated for helping prevent neural tube defects, iron deficiency anemia, and osteoporosis. The obstetrician-gynecologist plays an important preventive role by providing basic nutritional assessment; nutrition education; counseling concerning diet, weight, and exercise; and referral for special nutritional care as needed. The physician needs to be especially alert for serious nutrition-related problems such as eating disorders that pose a serious health risk and to stress the importance of good nutrition particularly to adolescent and elderly patients.
