Saw this on CNN and thought it was worth posting here:
WASHINGTON (AP) -- Try fewer burgers and more veggies after menopause: Cutting dietary fat may offer a long-sought protection against deadly ovarian cancer -- if you stick with the diet long enough.
Low-fat diets have long been promoted as a way to reduce the risk of different cancers, with decidedly mixed results when put to the test. But this week, researchers unveiled the first hard evidence that switching to a low-fat diet late in life can lower the odds of ovarian cancer, a malignancy with a particularly dismal survival rate.
The study tracked almost 40,000 women ages 50 to 79, some of whom were assigned to cut the total fat in their diets to 20 percent of calories -- from an average of 35 percent -- while others continued their usual diets. For the first four years, the menu changes didn't make a difference. But those who kept the fat low for eight years cut their chances of ovarian cancer by 40 percent, researchers reported in the Journal of the National Cancer Institute.
