Daily grape consumption may help alleviate
pain associated with symptomatic
osteoarthritis of the knee and improve joint
flexibility and overall mobility, a research said.
This is possible because of polyphenols
(antioxidants) found in grapes.
"Our findings provide promising data that
links grape consumption to two very
important outcomes for those living with knee
osteoarthritis: reduced pain and
improvements in joint flexibility," said Shanil
Juma from Texas Woman's University, US.
During the study, researchers assigned 72
men and women with knee osteoarthritis (OA)
to either consume grapes in the form of a
whole grape freeze-dried powder or a placebo
The results showed that both men and women
consuming a grape-enriched diet had a
significant decrease in self-reported pain
related to activity and an overall decrease in
total knee symptoms.
This beneficial effect was more pronounced in
Evidence of increased cartilage metabolism
was observed in men consuming the grape-
enriched diet, the study noted.
Osteoarthritis is more likely to occur in
people over 45 years of age, and women are
more likely to have osteoarthritis than men.
