Cervical cancer is associated with human papillomavirus (HPV), which has also been implicated in cancers of the vulva, vagina, anus, and oropharynx. Almost 300 million women worldwide have been infected with HPV, one of the commoner sexually transmitted infections, and 5% of the 13 million new cases of cancer in the world have been attributed to HPV. In developed countries, screening for cervical cancer using the Pap test has identified pre-cancerous changes in the cervix, at least in those women with access to health care. Also an HPV vaccine programme is available in 45 countries. Screening and prevention programmes have limited availability in developing countries although inexpensive low technology programmes are being developed, but access to treatment is also limited. If applied globally, HPV vaccination at 70% coverage could save the lives of 4 million women from cervical cancer, since most cases occur in developing countries.
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.
Women's empowerment relates to women's ability to make life choices (158). Higher levels of empowerment were associated with increased income, household decision-making, control over resources, and utilization of health resources (5, 158–160). For nutrition outcomes, empowerment was associated with increased income allocated to food expenditures and improved household food security (160, 161). It was also associated with increased dietary diversity, but had no impact on women's BMI (5, 161, 162). For example, mothers’ participation in empowerment activities through Helen Keller International's Enhanced Homestead Food Production (EHFP) program in Burkina Faso was associated with increased fruit intake (difference-in-differences = 15.8 percentage points, P = 0.02) and nearly statistically significant increases in meat intake and dietary diversity (163). Participation was also associated with decreased prevalence of underweight (difference-in-differences = −8.7 percentage points, P < 0.01) but not overall mean BMI (163). In addition, the EHFP program in Bangladesh and Nepal was associated with decreasing trends in maternal anemia (anemia prevalence decreased by a magnitude of 12%, P = 0.075 in Bangladesh, and 26%, P = 0.009 in Nepal) (160). However, this was not consistent with findings from Cambodia (160).
We live in a modern world with amazing advancements in technology, yet our soil lacks minerals that it once contained causing whatever grows out of it (i.e. fruits, vegetables, and whole foods) to be significantly lower in minerals than it once was. Not only is our soil different, but our food takes a long time to get to us! Unless we’re growing our own whole food in our gardens, picking it out with our bare hands, and washing it off before eating, most likely our produce has been picked weeks before it reaches your grocery store and is purchased by you. This entire process can take weeks and cause nutrients to be depleted from the whole food (2).
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.
As women, many of us are prone to neglecting our own dietary needs. You may feel you’re too busy to eat right, used to putting the needs of your family first, or trying to adhere to an extreme diet that leaves you short on vital nutrients and feeling cranky, hungry, and low on energy. Women’s specific needs are often neglected by dietary research, too. Studies tend to rely on male subjects whose hormone levels are more stable and predictable, thus sometimes making the results irrelevant or even misleading to women’s needs. All this can add up to serious shortfalls in your daily nutrition.
Changes in the way research ethics was visualised in the wake of the Nuremberg Trials (1946), led to an atmosphere of protectionism of groups deemed to be vulnerable that was often legislated or regulated. This resulted in the relative underrepresentation of women in clinical trials. The position of women in research was further compromised in 1977, when in response to the tragedies resulting from thalidomide and diethylstilbestrol (DES), the United States Food and Drug Administration (FDA) prohibited women of child-bearing years from participation in early stage clinical trials. In practice this ban was often applied very widely to exclude all women. Women, at least those in the child-bearing years, were also deemed unsuitable research subjects due to their fluctuating hormonal levels during the menstrual cycle. However, research has demonstrated significant biological differences between the sexes in rates of susceptibility, symptoms and response to treatment in many major areas of health, including heart disease and some cancers. These exclusions pose a threat to the application of evidence-based medicine to women, and compromise to care offered to both women and men.
