Brightly-coloured fruit and veg may protect against arthritis

You should aim for 8-10 portions of fruit and vegetables a day.

Brightly-coloured fruit and veg may protect against arthritis: "Rheumatoid arthritis currently affects around 1% adults in the UK. Previous studies have suggested that vitamin C and the pigment beta-cryptoxanthin, both of which are found in brightly-coloured fruit and veg, may act as antioxidants, and protect the body against the oxidative damage which can cause inflammation.

The Manchester team, based in the Arthritis Research Campaign's Epidemiology Unit, worked with researchers from the Institute of Public Health at the University of Cambridge to analyse health questionnaires and diet diaries by over 25000 45-74 year-olds; completed as part of the EPIC (European Prospective Investigation of Cancer) Norfolk study of diet and chronic disease in the 1990s. They then followed-up the participants over a nine year period to identify new cases of inflammatory polyarthritis (IP), including rheumatoid arthritis.

Dr Dorothy Pattison, who led the research, said: "We found that the average daily beta-cryptoxanthin intake of the 88 patients who had developed inflammatory polyarthritis was 40% lower than those who hadn't, and their intake of another carotenoid, zeaxanthin, was 20% lower.

"Those in the top third for beta-cryptoxanthin intake were only half as likely to develop IP as those in the lowest third, and vitamin C was also found to be an important factor."

The findings appear to confirm previous evidence that a modest increase in fruit and vegetables containing beta-cryptoxanthin and vitamin C, equivalent to one glass of freshly-squeezed orange juice each day, might help to protect against developing inflammatory joint diseases.

Really great blog! I noticed a mention about arthritis association . I thought you might be interested to hear that both my parents and several of their friends have had problems with arthritis and we have been very lucky to have come across Bioflow. They are sold at arthritis association and they have been worth every penny. They don't seem to work for everyone but they have helped reduce the pain in my parents arthritis so that they almost don't notice it any longer. They'd still be taking painkillers if it wasn't for wearing a Bioflow on their wrist
