It is estimated that more than a third of adults over the age of 65 have a degenerative joint disease known as osteoarthritis. And, according to the Centers for Disease Control and Prevention, arthritis of the knee is particularly severe and common in older women.

I recently came across an article in the AARP newsletter that discussed this issue and referenced an interesting study funded by the U.S. National Heart, Lung and Blood Institute. The study suggests that women who drink up to six glasses of fat-free or low-fat milk per week are able to delay the effects of arthritis in their knees.

Unfortunately, the study indicated that men did not experience a similar decline in the progression of knee osteoarthritis. Oddly enough, the study also showed that consuming other dairy products, such as yogurt or cheese, did not reduce joint deterioration at all. In fact, women who consumed more cheese displayed faster deterioration.

The researchers who took part in the study were unable to discern a cause-effect explanation for what they found. However, when the team’s leader, Bing Lu, M.D., was asked by the New York Times whether people with osteoarthritis should drink milk, his answer was simple: “Yes, low-fat or fat-free milk.”

Given some of the foods and beverages that are rumored to treat osteoarthritis, such as shark cartilage and snake venom, I’ll take a cold glass of milk every time.
