B12: Like folic acid, B12 is essential for healthy nervous system development and function. Pregnant women who are vegans or vegetarians may fall short on B12, since it is present in animal protein and to a lesser extent in dairy. Teenage and adult women need 2.4 mcg. Recommended levels rise to 2.6 mcg for pregnant women and 2.8 mcg for lactating women.
Women often received micronutrient supplements during antenatal and postnatal care (13, 35–42, 51, 60), and, as such, supplementation was often targeted to pregnant and lactating women. The delivery of micronutrient supplementation commonly occurred in health care settings for at-home consumption. Community-based antenatal care that involved home visits by community health workers was also a common delivery platform for supplementation delivery. There were some studies that reported micronutrient supplementation to adolescents, women of reproductive age, pregnant women, and women with young children outside of the antenatal care setting. These included primary health care clinics, home visits, community centers, pharmacies, and workplaces (32, 38–43, 45, 52, 53). Adolescent girls were also reached by community- and school-based programs (26, 41, 46). School-based programs were more efficacious in reducing rates of anemia among adolescent girls, compared with the community-based interventions (26, 46). However, many of the reported studies to date involved small samples of adolescents in controlled settings, and additional research is needed on the effectiveness of these programs (59, 62).
Fortunately, this trend is not across the board; on the cover of the January issue of Shape, Mandy Moore is in a black leather jacket so that her ensemble kind of resembles Wahlberg’s. This is not to say that Shape always covers up its cover women: Kate Walsh (right) was famously naked on her Shape cover (“How She Stays This Hot At 44!”), while The Biggest Loser’s Alison Sweeney also favored a red bikini.
Men who choose to drink and can do so responsibly may benefit from one to two drinks a day, counting 5 ounces of wine, 12 ounces of beer, or 1.5 ounces of spirits as one drink. But women face an extra risk: Even low doses of alcohol can raise their risk of breast cancer. So women who choose to drink might be wise to limit themselves to half as much as men.
Calcium: For adult women aged 19-50, the USDA recommended daily allowance is 1,000 mg/day. For women over 50, the recommended daily allowance is 1,200 mg/day. Good sources of calcium include dairy products, leafy green vegetables, certain fish, grains, tofu, cabbage, and summer squash. Your body cannot take in more than 500 mg at any one time and there’s no benefit to exceeding the recommended daily amount.
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).
Anemia can deplete your energy, leaving you feeling weak, exhausted, and out of breath after even minimal physical activity. Iron deficiency can also impact your mood, causing depression-like symptoms such as irritability and difficulty concentrating. While a simple blood test can tell your doctor if you have an iron deficiency, if you’re feeling tired and cranky all the time, it’s a good idea to examine the amount of iron in your diet.
Another major difference between the January covers we picked up: the scantily clad women versus coverboy Mark Wahlberg, who got to keep all of his clothes on. Shields (“Fitter Than Ever At 52!”) and Menounos (“Huge career. New fiancé. Then a brain tumor” right next to the shot of her in a teeny red bikini.) were not so fortunate. Maybe it’s on purpose: Menounos appears happy to show off her huge engagement rock as well as her impossibly flat abs, while Shields has been modeling since she was 11 months old, although hardly in such an unappealing posture as this one.
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.”
