What's a Woman To Do?

The results of two recent women's health studies have questioned the value of two widely recommended measures: calcium pills and vitamin D to prevent broken bones, and low-fat diets to ward off heart disease and colon cancer.

So Denise Grady, in a New York Times story, reasonably asks: What's a woman to do?

Should women abandon hope, since it looks as if nothing works? Abandon guilt and assume diet makes no difference? Or muddle on with salad and supplements, just in case?

The studies — part of the same government research project that in 2002 found hormone treatment for menopause did more harm than good — have confused women and prompted renewed examination of the regimens that many have been carefully following. Researchers find themselves parsing the results, and debating about how far the scientific rules can be stretched when it comes to measuring results and searching for evidence in smaller groups of patients within a large study.

The researchers admit that the findings were an unexpected and puzzling challenge to firmly held, almost religious beliefs about nutrition and health. And though some experts said the results meant women should look for other ways to prevent heart disease, cancer and bone loss, the scientists who conducted the studies insisted that hints of benefit in parts of the data could not be ignored.
