Show FiinGSS Tips The study revealed that more than a third, of them developed some kind of musculoskeletal complaint within a year of running the race. As might be expected, increased mileage meant an increased rate of injury. Of those who ran less than 9 miles a week, about 20 reported some kind of injury; at 30 miles a week, about 50 were affected. ' t Two of the most common cancers in the United States, bowel and breast, seem to bear a real relationship to dietary fat and fiber content. Putting more veggies and less red meat in our diets may be good, not only for our budgets, but for protection against cancer-so says the May 1983 Harvard Medical School Health Letter. Based on population studies, st-udies, bowel cancer is more common among groups of people that consume high amounts of animal fat and little fiber--both generally go hand in hand. In Africa and Asia, where fat intake approximates half that of the American diet, women have a much lower incidence of breast cancer than American women. In the U.S. breast cancer also occurs less frequently in vegetarians. A report in the New England Journal of Medicine links all of this to different levels of estrogen created by the vegetarian diet. And given that estrogens influence influ-ence the growth of breast tissue, this study offers some rational as to how a vegetarian diet might protect against breast cancer. At any rate we would all do better in our nutritional life styles if we would consume more fruits, vegetables, and whole grains. Bowel and breast cancer reduction are only two, among many reasons, for making the shift. Walking-Another boost Although aerobic exercise seems, in general, to be a good thing for health, running and jogging are far from trouble-free. (So what else is new.) Scientists from the Centers for Disease Control in Atlanta surveyed participants in the Peachtree Road Race. This 10 kilometer (6.2 miles) event attracts an annual crowd of 25,000 runners. |
