Antioxidants’ joint health benefits questioned
Antioxidants like vitamins A, C, and E and the carotenoids do not benefit joint health, says a new study with almost 200,000 women.
Scientists from Brigham and Women's Hospital in Boston report that antioxidant intake of 184,643 US women participating in the Nurses’ Health Study and Nurses’ Health Study II cohorts did not reduce the risk of developing either rheumatoid arthritis or systemic lupus erythematosus.
The researchers used food frequency questionnaires to measure intakes of vitamins A, C, and E and alpha-carotene, beta-carotene, beta-cryptoxanthin, lycopene, lutein, and zeaxanthin from both foods and supplements.
