Avoid arthritis - eat carrots | | Drinking a glass of orange juice a day may help stave off arthritis, new
research suggests. Certain carotenoids, compounds commonly found in some
fruits and vegetables, appear to be responsible.
The findings from previous studies have suggested that dietary carotenoids,
the chemicals responsible for the orange and yellow coloring of fruits and
vegetables, can reduce inflammation through antioxidant effects.
Dr. Alan J. Silman, from The University of Manchester in the UK, and
colleagues analyzed data from a study of more than 25,000 subjects to
investigate the association between dietary carotenoids and arthritis risk.
Between 1993 and 2001, the subjects were followed to assess the occurrence
of arthritis affecting multiple joints.
The researchers’ findings appear in the American Journal of Clinical
Nutrition.
Eighty-eight subjects developed arthritis during follow-up and they were
matched to 176 healthy comparison subjects.
Average daily intakes of the carotenoids beta-cryptoxanthin and zeaxanthin
were 40 and 20 percent lower, respectively, for arthritis patients compared
with healthy subjects. By contrast, consumption of two other well-known
carotenoids, lutein and lycopene, did not seem to protect against arthritis.
Further analysis showed that subjects with the highest beta-cryptoxanthin
and zeaxanthin intake were about half as likely to develop inflammatory
polyarthritis than those with the lowest intake.
“These data add to a growing body of evidence that some dietary
antioxidants, such as the carotenoids beta-cryptoxanthin and zeaxanthin as
well as vitamin C, may be protective against the development of” arthritis,
the authors conclude.
