Could your hip bones use a little tofu? Scientists report that moderate intake of soy-at least the amount found in about 1.75 ounces of tofu-was associated with reduced risk of hip fractures among women in the Singapore Chinese Health Study. Thats an amount of soy higher than the low levels of consumption in the West, noted lead researcher Woon-Puay Koh, MD, of the National University of Singapore.
You know you should eat more fish. The American Heart Association recommends at least two servings a week, especially fish high in hearthealthy omega-3 fats. But fresh fish can be expensive and spoils quickly. Maybe its time to rediscover canned fish.
Can your body really absorb the vitamin D in fortified orange juice, given that the vitamin dissolves in fat (as in fortified milk) but not water? A new study says it can, adding fortified OJ to the limited list of significant food and beverage sources of vitamin D.
One of the longer clinical trials to compare a low-carb diet with a low-fat, low-calorie weight-loss regimen reports that both were effective for losing weight-but the low-carb diet also delivered a heart-health bonus.
I f youre at risk for osteoarthritis of the knee, light exercise such as walking or bowling can reduce your odds of develop- ing that painful condition. But strenuous exer- cise such as skiing, soccer, running or playing basketball can lead to cartilage damage and start an osteoarthritis cascade, a new study warns.

Along-term followup to the Diabetes Prevention Program trial has good news for the estimated 57 million Americans with high blood-sugar levels that put them in danger of developing diabetes: Intensive lifestyle changes aimed at modest weight loss reduced the rate of developing type 2 diabetes by 34% compared with a control group in people at high risk for the disease. Reducing dietary fat and calories, exercising such as walking about 150 minutes weekly and losing weight also proved more effective in diabetes prevention than metformin, an oral diabetes drug.
Vitamin Ds important role in bone health, already linked to protection against osteoporosis, may extend to joints and prevention of the most common form of arthritis. A new study reports that men with insufficient vitamin D levels were twice as likely to have hip osteoarthritis as those with normal vitamin D.
Are refined carbohydrates worse than saturated fat? Thats the provocative headline of a recent American Journal of Clinical Nutrition editorial commenting on a large new Danish study of diet and heart-attack risk. Author Frank B. Hu, MD, PhD, of the Harvard School of Public Health, explains how, for decades, the diet-heart paradigm thats been the driving force behind dietary recommendations has emphasized the heart-health dangers of saturated fat and cholesterol. Thats led to a decrease in Americans total and saturated fat intake, while carbohydrate consumption went up. Until recently, Dr. Hu adds, the role of carbohydrates in cardiovascular disease has received scant attention.
Blueberries have earned their reputation as a superfruit in part because of their high content of antioxidant polyphenols. (In fact, of course, theres no such thing as a superfruit-all fruits have some super qualities.) New research put those polyphe-nols to the test against metabolic syndrome, a complex of conditions, including central obesity (high waist-hip ratio), high blood pressure, high serum cholesterol and insulin resistance, that increases the risk of heart disease and diabetes.
T hat morning glass of OJ might be doing some good for your cholesterol numbers. In a new study published in Nutrition Research, Brazilian scientists report that orange juice made from concentrate reduced unhealthy LDL choles- terol levels in patients with high cholesterol.
