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.
It’s been a while since I’ve picked up any of these, but when I did, the messages weren’t nearly as body-positive. In fact, a quick perusal of other Shape magazine covers from the 1980s (I was probably still reading Seventeen then, but still) shows a bunch of celebrity cover models who would like you to get off the couch immediately, with demands like “Get Strong!” and “Push For Fitness!” Also suspect: “How To Think And Eat Like A Thin Person” and “Is Food Your Lover? How To End The Affair.”
Lipid-based nutrient supplement (LNS) programs are intended to enrich diets with micronutrients and essential fatty acids (97), and are often used in emergency settings to meet nutritional needs of pregnant and lactating women (98). Of the studies that report on women's health outcomes, LNSs provided to pregnant and lactating women increased body weight and midupper arm circumference, particularly of multiparous women and women >25 y of age (99). They were associated with increased plasma α-linoleic acid, although not plasma lipids and other fatty acids (100). LNSs did not affect women's immune responses, particularly pregnant women's anti-malarial antibody responses (101). There was limited evidence connecting LNS supplementation to unhealthy weight gain and retention, and this is being explored in ongoing studies in Ghana (97).
When you’re at the bar or a party and starving, your options aren’t always the best. But if it’s bruschetta, chips and salsa, or wings, go for the chicken (though nuts would be even better). Protein fills you up faster than carbs do, making it less likely that you’ll overeat, says Christopher Ochner, Ph.D., a research associate at New York Obesity Nutrition Research Center at St. Luke's Roosevelt Hospital Center. And since it’ll keep you satiated longer, you won’t be as tempted when your friend orders a brownie sundae or brings out a tray of blondies.
These challenges are included in the goals of the Office of Research on Women's Health, in the United States, as is the goal of facilitating women's access to careers in biomedicine. The ORWH believes that one of the best ways to advance research in women's health is to increase the proportion of women involved in healthcare and health research, as well as assuming leadership in government, centres of higher learning, and in the private sector. This goal acknowledges the glass ceiling that women face in careers in science and in obtaining resources from grant funding to salaries and laboratory space. The National Science Foundation in the United States states that women only gain half of the doctorates awarded in science and engineering, fill only 21% of full-time professor positions in science and 5% of those in engineering, while earning only 82% of the remuneration their male colleagues make. These figures are even lower in Europe.
Most vegetarians eat milk products and eggs, and as a group, these lacto-ovo-vegetarians enjoy good health. A healthful vegetarian diet falls within the food pyramid guidelines offered by the USDA. However, meat, fish and poultry are major sources of iron, zinc and B vitamins, so pay special attention to these nutrients. Vegans (those who eat only plant-based food) should consult a health care professional about adding vitamin and mineral supplements; make sure you consume sufficient quantities of protein, vitamin B12, vitamin D and calcium.
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.
What you eat is even more important as you enter your 40s. Women need protein (meat, fish, dairy, beans, and nuts), carbohydrates (whole grains), fats (healthy oils), vitamins, minerals, and water. These foods have been linked to some disease prevention, such as osteoporosis, high blood pressure, heart disease, diabetes, and certain cancers. The American Academy of Family Physicians supports the development of healthy food supply chains in supplemental nutrition programs so as to broaden the availability of healthy food.
Although canola oil appears to be good for the cardiovascular system, two Harvard studies have raised concerns that ALA might be bad for the prostate. In 1993, the Health Professionals Follow-up Study of 47,781 men published a major evaluation of dietary fat and prostate cancer. It found that saturated fat from animal sources such as red meat and whole-fat dairy products was linked to a 2.6-fold increase in prostate cancer. But the study also provided some disquieting news about ALA: Men who consumed the most ALA were 3.4 times more likely to be diagnosed with prostate cancer than those who had the lowest dietary intake.
The guidelines also establish ranges (called acceptable macronutrient distribution ranges or AMDR) for fat, carbohydrates and protein, instead of exact percentages of calories or numbers of grams. The report maintains that since all three categories serve as sources of energy, they can, to some extent, substitute for one another in providing calories.
Trimming some fat may eliminate some guilt, but be warned: Buying foods labeled “low-fat,” “non-fat,” or “fat-free” may encourage you to eat up to 50 percent more calories, according to three studies by Cornell University’s Food and Brand Lab. Fat’s not the issue when it comes your weight since most of these foods only have about 15 percent fewer calories than their regular counterparts. Go for the full-fat version and eat less—you probably will naturally since they taste better.
Evaluations of protein-energy supplementation were limited to specific situations and contexts, and few studies evaluated national-scale programs (14, 33). National-level protein-energy supplementation programs for women and adolescent girls are expensive and challenging to implement compared with other efficacious interventions (33). Procuring, preparing, and distributing food and appropriately targeting women most in need (e.g., women below the poverty line, women who have or are at high risk of malnutrition, etc.) present challenges to protein-energy supplementation interventions (33).
