The increasing focus on Women's Rights in the United States during the 1980s focused attention on the fact that many drugs being prescribed for women had never actually been tested in women of child-bearing potential, and that there was a relative paucity of basic research into women's health. In response to this the National Institutes of Health (NIH) created the Office of Research on Women's Health (ORWH)[154] in 1990 to address these inequities. In 1993 the National Institutes of Health Revitalisation Act officially reversed US policy by requiring NIH funded phase III clinical trials to include women.[119] This resulted in an increase in women recruited into research studies. The next phase was the specific funding of large scale epidemiology studies and clinical trials focussing on women's health such as the Women's Health Initiative (1991), the largest disease prevention study conducted in the US. Its role was to study the major causes of death, disability and frailty in older women.[155] Despite this apparent progress, women remain underepresented. In 2006 women accounted for less than 25% of clinical trials published in 2004,[156] A follow up study by the same authors five years later found little evidence of improvement.[157] Another study found between 10–47% of women in heart disease clinical trials, despite the prevalence of heart disease in women.[158] Lung cancer is the leading cause of cancer death amongst women, but while the number of women enrolled in lung cancer studies is increasing, they are still far less likely to be enrolled than men.[119]
Having the proper footwear is essential for any workout, and for winter runs, that means sneaks with EVA (ethylene vinyl acetate), says Polly de Mille, an exercise physiologist who oversees New York Road Runner's Learning Series for first-time New York City Marathon runners. “Polyurethane tends to get really stiff and cold in the winter, which could increase your risk of injury.” Another important feature is a waterproof and windproof upper: Look for shoes made with Gortex, or wrap your mesh uppers in duct tape to keep feet dry and warm.
So we can applaud some of the efforts of Women’s Health. As editor Amy Keller Laird announced in that Jan/Feb issue, the magazine “will no longer be using fitness models in our monthly ‘15-Minute Workout.’ We’ll feature readers of various body types and sizes,” like the refreshingly normal-sized Morgan Gibson Kanner, hurling a weight plate around in stretchy workout clothes. As progressive as the layout is, Laird points out that “it’s logistically difficult to book nonmodels who have day jobs”; sounds like she should hook up with Willcox’s modeling service.
After 40, your hormone levels (estrogen) drop. This causes your insulin (hormone that helps your body use sugar) rise. Your thyroid levels go down. This combination makes you hungrier. You end up eating more and burning fewer calories. Much of the weight gain occurs around your belly. Eat more foods with fiber (berries, whole grains, nuts) to fill you up and help you eat less. Aim for 25 grams of fiber each day after the age of 40. Other ways to increase your metabolism include:
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.
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).

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.
