According to study results published online April 7, 2014 in Arthritis Care and Research, women who frequently drink fat-free or low-fat milk may delay the progression of knee osteoarthritis. The finding was not the same for men. Also, not all dairy was associated with this effect -- women who ate cheese had an increase in the progression of knee osteoarthritis. Yogurt did not impact progression of osteoarthritis in men or women.
In the study, 2,148 participants with knee osteoarthritis were recruited for the Osteoarthritis Initiative. Dietary data was collected at the study onset and joint space width was measured by x-ray. Researchers found that as milk intake increased from 0 to less than 3 , 4-6, and more than 7 glasses per week, the joint space width in women decreased.
