There's not much doubt about this one: Women need more iron than men, because they lose iron with each menstrual period. After menopause, of course, the gap closes. The RDA of iron for premenopausal women is 18 mg a day, for men 8 mg. Men should avoid excess iron. In the presence of an abnormal gene, it can lead to harmful deposits in various organs (hemochromatosis). Since red meat is the richest dietary source of iron, it's just as well that men don't need to wolf down lots of saturated fat to get a lot of iron.

Hysterosalpingography (HIS-tur-oh-sal-ping-GOGH-ru-fee): This is an x-ray of the uterus and fallopian tubes. Doctors inject a special dye into the uterus through the vagina. This dye shows up in the x-ray. Doctors can then watch to see if the dye moves freely through the uterus and fallopian tubes. This can help them find physical blocks that may be causing infertility. Blocks in the system can keep the egg from moving from the fallopian tube to the uterus. A block could also keep the sperm from reaching the egg.
Not everyone who is underweight suffers from an eating disorder, but anorexia and bulimia are serious health problems in this country; an estimated 500,000 women suffer from anorexia, and 1 to 2 million women struggle with bulimia. Women with anorexia nervosa starve themselves and/or exercise excessively, losing anywhere from 15 percent to 60 percent of their normal body weight. Some die. Women with bulimia nervosa binge on large quantities of food—up to 20,000 calories at one time—and then try to get rid of the excess calories. Some purge by inducing vomiting, abusing laxatives and diuretics or by taking enemas. Others fast or exercise to extremes.

Income-generation interventions largely target adult women (women of reproductive age, women with young children, and older women). Many microfinance and loan programs are targeted to women because of their likelihood to pay back the loans, although women with lower education levels and smaller businesses do not benefit to the same degree as women who are educated or who have bigger businesses (165). There was limited evidence of such interventions targeting adolescent girls (169). In order to understand the potential impact of income-generating activities on adolescents, more information is needed about the pathways by which adolescents contribute to their own food security, the degree to which they rely on their caregivers to meet their nutritional needs, and how those dynamics change with the age of adolescents (169). Training, workshops, and extension activities were often delivered through community centers, community groups, and financial institutions (165). Other affiliated interventions, such as agricultural extension and nutrition education, were provided at the community level and at home visits (160, 173). These delivery platforms were effective at reaching women, including low-income women, particularly when they engaged with existing community groups (e.g., self-help, farmers’, and women's groups) (160, 161, 167, 169, 172, 173).

Nutrition-sensitive approaches are difficult to link to women's nutritional status (5, 102). This is due to limited measurement of benefits to program beneficiaries, families, households, and communities, limited timeframes to evaluate long-term impact, logistical and political realities that make implementation difficult, and different priorities of different stakeholders in multisectoral programs (102). Many nutrition-sensitive approaches, as will be described, thus focus on more distal measures of impact (e.g., coverage, knowledge) and not more proximal measures of women's nutritional status (e.g., BMI, anemia status, etc.).
