In the stereotypical Ozzie and Harriet family of the 1950s, men ruled the roost while women ruled the roast. That's no longer true (if it ever was), but in most households women are still in charge of nutrition. They stock the pantry, plan the menus, and fill the plates. In most households it's a good thing, since the average woman knows more about nutrition than the average man. But when it comes to optimal nutrition, there are differences between the sexes. The differences are subtle, but they may affect a man's health.
Iron is one of the keys to good health and energy levels in women prior to menopause. Foods that provide iron include red meat, chicken, turkey, pork, fish, kale, spinach, beans, lentils and some fortified ready-to-eat cereals. Plant-based sources of iron are more easily absorbed by your body when eaten with vitamin C-rich foods. So eat fortified cereal with strawberries on top, spinach salad with mandarin orange slices or add tomatoes to lentil soup.
Vitamin D: Over the past decade, dozens of studies have revealed many important roles for vitamin D, the nutrient that skin cells produce when they are exposed to sunlight. The recommended daily intake of Vitamin D is 600 IU per day, although recommended levels are under review. If you avoid the sun or live in the northern half of the U.S., ask your doctor whether your vitamin D level should be tested.
Women's empowerment relates to women's ability to make life choices (158). Higher levels of empowerment were associated with increased income, household decision-making, control over resources, and utilization of health resources (5, 158–160). For nutrition outcomes, empowerment was associated with increased income allocated to food expenditures and improved household food security (160, 161). It was also associated with increased dietary diversity, but had no impact on women's BMI (5, 161, 162). For example, mothers’ participation in empowerment activities through Helen Keller International's Enhanced Homestead Food Production (EHFP) program in Burkina Faso was associated with increased fruit intake (difference-in-differences = 15.8 percentage points, P = 0.02) and nearly statistically significant increases in meat intake and dietary diversity (163). Participation was also associated with decreased prevalence of underweight (difference-in-differences = −8.7 percentage points, P < 0.01) but not overall mean BMI (163). In addition, the EHFP program in Bangladesh and Nepal was associated with decreasing trends in maternal anemia (anemia prevalence decreased by a magnitude of 12%, P = 0.075 in Bangladesh, and 26%, P = 0.009 in Nepal) (160). However, this was not consistent with findings from Cambodia (160).
While women tend to need fewer calories than men, our requirements for certain vitamins and minerals are much higher. Hormonal changes associated with menstruation, child-bearing, and menopause mean that women have a higher risk of anemia, weakened bones, and osteoporosis, requiring a higher intake of nutrients such as iron, calcium, magnesium, vitamin D, and vitamin B9 (folate).
For this comprehensive narrative review, we evaluated both nutrition-specific and nutrition-sensitive interventions. Nutrition-specific approaches are those that address the immediate determinants of nutrition (e.g., food and nutrient intake, diet-related practices and behaviors, disease, etc.), whereas nutrition-sensitive approaches are those that address the underlying determinants of nutrition (e.g., food security, access to resources, safe and hygienic environments, adequate health services, etc.) (5, 12). We evaluated the following nutrition-specific interventions described by Bhutta et al. (13, 14): nutrition counseling and education, micronutrient supplementation and fortification, protein and energy supplementation, and lipid-based supplementation. We also included the following nutrition-sensitive approaches described by Ruel and Alderman (5) and Bhutta et al. (14): health care; family planning; water, sanitation, and hygiene (WASH); empowerment; income-generation; education; and social protection. For each intervention, we 1) described the scale and coverage of the intervention, when available; 2) summarized the evidence of effectiveness for women's health and nutrition outcomes; and 3) described and evaluated the target population and delivery platforms, as described in the published articles and as summarized in Table 1. The delivery of interventions included the physical platforms, as well as the adherence and the implementation challenges of the different interventions.
A 55-year-old woman who gets less than 30 minutes of daily physical activity should eat five ounces of grains; two cups of vegetables; one and a half cups of fruit; three cups of milk; five ounces of meat and beans; five teaspoons of oils, and no more than 130 calories of additional fat and sugar. If she got 30 to 60 minutes of daily exercise, she could increase her intake to six ounces of grains; two and a half cups of vegetables; and up to 265 additional calories of fat and sugar.
