Adding on to the various health benefits of fruits and vegetables is another health benefit. They have the capability of reducing the risk of arthritis.
The beneficial compound in fruits and vegetables is carotenoid.
The new study suggested that dietary carotenoids, the orange and yellow pigments responsible for the colon of some fruits and vegetables, can reduce inflammation around joints, due to their antioxidative properties.
The study, led by Dr. Alan J. Silman at The University of Manchester, analyzed data from a study involving more than twenty-five thousand participants from 1993 to 2001 to determine if there is an association between dietary carotenoids and arthritis risk.
The participants were followed to assess the occurrence of arthritis affecting multiple joints. During the eight-year follow-up, eighty-eight participants developed arthritis.
On average, the arthritic patients had a forty percent lower daily intake of beta-cryptoxanthin and a twenty percent lower intake of zeaxanthin compared to the participants without arthritis.
In addition, participants who had the highest intake of beta-crytoxanthin and zeaxanthin were fifty percent less likely to develop inflammatory polyarthritis than those who had the lowest intake.
The study further found that consumption of two other carotenoids, lutein and Lycopene, did not seem to have a protective effect against arthritis.
