Fluids: Fluid needs increase as women age. The reason: Kidneys become less efficient at removing toxins. “Drinking more fluids helps kidneys do their job,” Schwartz says. “Unfortunately, thirst signals often become impaired with age, so people are less likely to drink enough water and other fluids.” Rather than fret about how many glasses to drink, Frechman says, check the color of your urine. "It should be clear or very pale colored. If it becomes darker, you need more fluid.”
Our review highlighted how a focus on delivery platforms could indicate who is missed by different nutrition interventions, by evaluating where there is overlap or divergence in where interventions are delivered (as represented in the Venn diagram in Figure 1). Our findings showed that a large proportion of nutrition-specific interventions were delivered at clinic-based settings or community-based health posts. Health centers are important delivery platforms, particularly for pregnant and lactating women (113, 210). However, only half of women worldwide even attend the appropriate number of antenatal care visits (with nearly 86% of women attending 1 visit) and only 59% receive appropriate postnatal care (211). Other delivery platforms, such as schools and universities, were more effective at reaching some adolescents and women of reproductive age. However, interventions delivered at “facilities” (schools, health clinics, health posts) require participation with those facilities, and participation is often limited because of time, costs, distance, and other responsibilities, including work and childcare (116). Facilities-based care is also more likely to miss certain groups, including older women.
What's a man to do? Fortunately, he does not have to choose between his bones and his prostate. The solution is moderation. The Baltimore Longitudinal Study of Aging, for example, found no link between a moderate consumption of calcium (about 800 mg a day, two-thirds of the RDA) and prostate cancer. In addition, a randomized clinical trial of calcium supplements of 1,200 mg a day found no effect on the prostate, but only 327 men were in the calcium group, and the supplementation lasted just four years. Finally, the Harvard scientists speculate that a high consumption of vitamin D may offset the possible risks of calcium, so a daily multivitamin may also help.
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.
The best evidence that ALA can protect the heart comes from the Lyon Diet Heart Study, a randomized clinical trial in Europe. It tested the effects of an ALA-enriched Mediterranean diet in 605 patients with coronary artery disease. Over a four-year period, the high-ALA diet produced a 72% reduction in heart attacks and cardiac deaths and a 56% lower risk of dying from any cause (including cancer). The Mediterranean diet differed from the standard Western diet in many respects, but because it contained a special canola oil margarine, the greatest difference was in its ALA content, which was nearly eight times higher in the protective diet.
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.”
