NEW YORK: A large study has found evidence that milk consumption may slow the progression of knee arthritis. According to the Centers for Disease Control and Prevention, osteoarthritis, a chronic joint disease, affects 14 percent of people over 25 and 34 percent of those over 65. In this study, researchers collected detailed health, diet and behavioural data on 2,148 men and women with knee osteoarthritis. They performed annual knee X-rays for the next four years, measuring the narrowing space between bones in the knee joint to gauge disease progression. They found that increasing milk consumption was associated with slower progression of the disease in women. In men, only those who consumed the most milk — seven or more glasses a week — saw the effect. More than 90 percent of the people in the study drank fat-free or low-fat milk, and the study did not find the effect with cheese and other dairy products.
Scientists pin down cause of runny nose
Washington: Scientists may have finally pinned down the cause of a runny nose, a mysterious ailment that affects millions across the globe. While many people call it the sniffles, scientists refer to it as “non-allergic rhinitis.” Although it is common, researchers had, until now, not figured out why this happens — suspects include air pollution, strong emotions, and even spicy food. Researchers at the University of Colorado School of Medicine, led by Thomas Finger, found cells lining the noses of mice that detect irritants and pass along the alert to pain-sensing nerve terminals. The nerves then release a substance that triggers the body’s defenses. The result, among other things, a runny nose and difficulty breathing. “What if we could deaden the pathway that the body takes to fight off an attack that, in this case, is not really threatening?” Finger said. It is not yet certain that the process is identical in humans, Finger said.
But if it is, additional research could find a way to help millions of people, he said. PTI
