Calcium: Although some bone loss is inevitable with age, women can slow the process by getting enough calcium and vitamin D. Women between the ages of 50 and 70 need 1200 mg of calcium and 600 IU of Vitamin D a day. Women older than 70 require 1200 mg of calcium and 800 IU of Vitamin D a day. Because the skin becomes less efficient at converting sunlight to vitamin D as we age, older women may need more vitamin D in the form of supplements. Talk to your doctor.
If you do decide to diet, you still need to maintain good nutrition. You want to cut back on calories, not nutrients. And while you want to reduce fat, don't eliminate it entirely. Some studies suggest that older women who maintain a higher body-fat percentage are less likely to suffer from osteoporosis and other conditions associated with menopause. Fat cells also retain estrogen, which helps maintain the calcium in your bones. Younger women should be careful, too: a low body fat percentage can lead to infertility; below 17 percent may lead to missed periods, also known as amenorrhea.

Women's health refers to the health of women, which differs from that of men in many unique ways. Women's health is an example of population health, where health is defined by the World Health Organization as "a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity". Often treated as simply women's reproductive health, many groups argue for a broader definition pertaining to the overall health of women, better expressed as "The health of women". These differences are further exacerbated in developing countries where women, whose health includes both their risks and experiences, are further disadvantaged.
