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.
Sweet chili peppers may not be a winter food, but continue eating them in your burritos, stir-fries, and soups, and you may burn more fat during your outdoor cold-weather runs. These not-hot veggies contain chemicals called capsinoids, which are similar to the capsaicin found in hot peppers. Combine capsinoids with 63-degree or cooler temps, and you increase the amount and activity of brown fat cells—those that burn energy—and give your metabolism an extra boost, according to a study published in the Journal of Clinical Investigation.
Give your body a little more credit: It tells you when you’re hungry—you may not be listening, though. Before chowing down because there’s only one slice of pie left or because the last guest arrived at the brunch, stop and check in with your stomach. “If you’re not hungry, make yourself a small plate and sip on some tea or coffee while everyone else digs in,” recommends Elle Penner, M.P.H., R.D., a MyFitnessPal expert. When your belly starts to finally grumble, food will be there.
Women's nutrition is often eclipsed by maternal nutrition. There are important linkages between maternal nutrition and the health, cognitive development, and earning potential of future generations (1). However, with reduced childbearing and longer life spans, women's experiences extend beyond motherhood (2). Interventions and policies that target women solely as mothers fail to account for women before they conceive, after they no longer engage with programs targeting maternal–child health, as well as those who never have children (3, 4). A woman's nutrition should matter not (only) because of her reproductive potential, but because it is fundamental to her rights as a person and to her well-being and ability to thrive (5–7). With increasing attention to the nutritional needs of adolescent girls (8, 9), in addition to the rising prevalence of overweight, obesity, and noncommunicable disease affecting women later in life (10), it is becoming more imperative that interventions reach women at all life stages.
Systematically report and evaluate women's nutrition outcomes in research and program evaluation documents in low- and middle-income countries, including outcomes for adolescents, older women, and mothers (as opposed to reporting on women's nutrition as child nutrition outcomes alone). When possible, report and evaluate differences by setting (e.g., rural compared with urban) and socioeconomic status.
Low-fat diets also can help you lose weight.16 But the amount of weight lost is usually small. You can lose weight and lower your risk for heart disease and stroke if you follow an overall healthy pattern of eating that includes more fruits, vegetables, whole grains and beans that are high in fiber, nuts, low-fat dairy and fish, in addition to staying away from trans fat and saturated fat.
The recommended daily intake for vitamin E is 15 mg. Don't take more than 1,000 mg of alpha-tocopherol per day. This amount is equivalent to approximately 1,500 IU of "d-alpha-tocopherol," sometimes labeled as "natural source" vitamin E, or 1,100 IU of "dl-alpha-tocopherol," a synthetic form of vitamin E. Consuming more than this could increase your risk of bleeding because vitamin E can act as an anticoagulant (blood thinner).
Before you convince yourself that you’re too busy to mediate, consider this: “Adding mediation to your daily fitness routine can be a crucial part of body transformation,” says Mark Fisher, founder of Mark Fisher Fitness in NYC. Find five to 10 minutes once or twice a day to focus on your breath, he suggests. “Taking the time to do this can help your body and brain de-stress and recover better from all your hard work at the gym and the office.”
Iodine is needed for normal mental development of the baby, but it can be difficult to get enough from food. Ways of increasing iodine intake include using iodised salt, eating fish and seafood weekly (see your health professional for advice about safe types and amounts of fish), or using a multivitamin supplement that contains iodine and is safe for pregnancy.
Our review found that protein-energy supplementation was largely targeted to pregnant and lactating women (19, 86–88, 90, 91); however, there were some studies that evaluated the delivery of protein-energy supplementation to households (92, 93) and adolescents (46). The only studies we found that evaluated the impact of protein-energy supplementation in older, healthy women were hospital-based studies in high-income countries (96). Delivery platforms varied depending on the target audience. The majority of studies targeted pregnant women through antenatal care or through antenatal care–associated community-based programs. National programs targeting low-income families had broader reach, although they targeted households and not women specifically (92). Additional research is needed for how women might best be reached (94). For programs that provided provisions for women to take home, there was also limited information about how much was shared with other members of the household. School-based programs targeting adolescents could be an important venue to target interventions to adolescents in the future. However, children and adolescents not in school would be missed. Despite limited evidence of impacts of energy and protein supplementation on the health of women, supplementation might be an important complement to other interventions (e.g., nutrition education and counseling) to ensure that women have the resources needed to implement other interventions successfully. Indeed, many large-scale programs for protein-energy supplementation are often complemented with nutrition education and counseling (33).
Calcium: “Getting enough calcium is important for all ages, but it's particularly important during adolescence and early adulthood, when bones are absorbing calcium,” says Heather Schwartz, MS, RD, a medical nutrition therapist at Stanford University Hospital and Clinics. Calcium and vitamin D are often paired in fortified foods such as milk. The reason: The body needs D in order to absorb calcium.
It sounds counterintuitive, but fatty fish are actually good for you because they deliver omega-3 polyunsaturated fatty acids (PUFAs), fats with cardiovascular and anti-inflammatory benefits. While fish oil capsules will help you meet your PUFA needs, studies have found that fish itself offers even more nutritional benefits, including vitamin D, selenium, and antioxidants. Among the best choices are salmon, albacore tuna, herring, and trout. Recommendations are for 1 gram of PUFAs daily for people with coronary heart disease and at least 250 to 500 mg daily for those who want to prevent it.
Women’s health magazines have always highlighted female celebrities at the peak of fitness: workout guru Jane Fonda next to a headline shouting “Perfect Your Body” on a 1987 Shape cover is a classic example. Peering at the local magazine counter this month, I noticed a lot of women’s health magazine still had life- and body-empowering messages, but they stressed the mental gains over the physical: “Your Best You!” next to Brooke Shields on the cover of Health; “Hot & Happy!” aside E!’s Maria Menounos. Shape magazine now even has an online section called #LoveMyShape, in which Orange Is The New Black star Danielle Brooks discusses how she learned to embrace her curves through her Lane Bryant ads, and model Katie Willcox wants you to know that you’re so much more than you see in the mirror.
It's easy to get lost in a killer playlist or Friends rerun on the TV attached to the elliptical, but mindless exercise makes all your hard work forgettable—and you can forget about seeing results too. “There is a huge difference between going through the motions of an exercise and truly thinking, feeling, and engaging the key muscles,” says Kira Stokes, master instructor at the New York City location of indoor cycling studio Revolve. “Be conscious of and enjoy the sensation of your muscles contracting and the feelings of growing stronger and more powerful with each rep.”
