A related issue is the inclusion of pregnant women in clinical studies. Since other illnesses can exist concurrently with pregnancy, information is needed on the response to and efficacy of interventions during pregnancy, but ethical issues relative to the fetus, make this more complex. This gender bias is partly offset by the iniation of large scale epidemiology studies of women, such as the Nurses' Health Study (1976), Women's Health Initiative and Black Women's Health Study.
In addition to diet, exercise and other lifestyle factors can also play an important role in bone health. Smoking and drinking too much alcohol can increase your chances of developing osteoporosis, while weight-bearing exercise (such as walking, dancing, yoga, or lifting weights) can lower your risk. Strength or resistance training—using machines, free weights, elastic bands, or your own body weight—can be especially effective in helping to prevent loss of bone mass as you age.
Omega-3s: These essential fatty acids, EPA and DHA, play many roles in the body, including building healthy brain and nerve cells. Some studies show that omega-3s, especially DHA, can help prevent preterm births. Even women who don't plan to have children should be sure to get plenty of omega-3s. These healthy oils have been shown to reduce the risk of heart disease, the number one killer of women.
