Knee pain from osteoarthritis (OA) is a fairly common complaint. Cartilage damage can occur from a variety of factors including injuries, aging, and certain illnesses. Keeping the muscles around the knee strong and managing weight are two of the typical strategies to reduce pain.
A recent analysis of data from two large studies of patients with arthritis revealed another potential tool to help keep pain in check. Patients who ate more fiber had fewer symptoms and less likelihood of knee pain becoming worse over time. This result is a correlation and not a definite cause and effect. However, I think it is another good reminder to eat well and get enough fiber in our diets.
People who consumed the most fiber—21 grams a day on average in the Osteoarthritis Initiative, and 26 grams in the Framingham study— had a 30 and 61 percent lower risk of OA symptoms, respectively, compared with people who ate the least. Higher fiber intake also reduced the likelihood of knee pain worsening among participants who had that symptom at the start of the studies.
