Grape polyphenols might help make painful knees less sore and more flexible.

Scientists say eating grapes shows promise for helping quell knee pain associated with osteoarthritis. Polyphenols in grapes could be a way to improve cartilage health that becomes weakened and destroyed with aging and injury, causing the knee joint to lose mobility and flexibility.

Grapes help osteoarthritis pain

In addition to helping the knee joint with flexibility, grape powder in the study was shown to improve symptoms of pain that occurs from friction in the knee joint. Osteoarthritis happens when the joint loses its cushioning fluid. Walking can become difficult which in turn can lead to falls and other health problems for millions diagnosed with osteoarthritis.

The study compared osteoarthritis symptoms in 2 groups

Researchers compared how grapes could help osteoarthritis symptoms in two groups of participants for the study that included 72 men and women suffering from the common condition.

Over the 16-week study period women with osteoarthritis were found to gain the most benefit from the compounds in grapes. The condition is more prevalent among women.

During the study cartilage growth factor and ability to perform hard activities improved for people who consumed grapes compared to the placebo group with the exception of those over age 65.

The finding was presented at the Experimental Biology conference in San Diego, California last week. Men who consumed a diet enriched with grapes had a greater boost in an important cartilage growth factor (IGF-1) that may have a protective effect on preventing osteoarthritis. The same effect of higher levels of IGF-1 was not seen in women however.

Both groups had increased blood biomarkers that indicate inflammation, but was lower those given grape powder versus placebo.

Lead study author Shanil Juma, Ph.D of Texas Woman's University said in a press release the finding shows grapes might improve two important symptoms associated with osteoarthritis of the knee - pain and knee flexibility. More studies are needed to understand why there was a difference in outcomes between genders. age differences and to understand the results of the inflammation biomarkers.

The finding means compounds in grapes might help knee osteoarthritis, but questions remain that require more research. Regardless, grapes are good for health and may even help thwart heart disease.
