Antioxidants no help at keeping arthritis and lupus at bay
Despite earlier research that found a link between antioxidant intake and a lower risk of rheumatoid arthritis and lupus in women, new study findings are reporting antioxidants may not actually offer any protection after all.

Researchers from Brigham and Women's Hospital in Boston tracked nearly 185,000 women for up to 24 years as part of the Nurses' Health Study and Nurses' Health Study II.

The women who were free of rheumatoid arthritis and lupus at the outset of the study completed detailed questionnaires on their diets and supplement use.

The researchers used those reports to estimate the women's daily intakes of powerful antioxidants, including vitamins A, C and E, as well as alpha- and beta-carotene, lycopene, lutein, beta-cryptoxanthin and zeaxanthin.
Between 1980 and 2004, 787 women were newly diagnosed with rheumatoid arthritis, while 192 were diagnosed with lupus.

Researchers found that women with higher antioxidant intakes tended to maintain a healthier lifestyle overall, including more physically activity, and were less likely to smoke.  When those factors were taken into account, antioxidant consumption itself showed no protective effect against either disease.

The findings contradict hints from earlier research that women with higher intake of antioxidants might have lower risks of developing these diseases.
The findings were reported in the American Journal of Epidemiology.
