Association between beverage consumption and risk of rheumatoid arthritis: a prospective study from the French E3N Cohort.

In a large cohort of women, tea, alcohol, and sugar-sweetened soft drinks consumption was not associated with RA risk, whereas consumptions of coffee (especially caffeinated coffee), and artificially-sweetened soft drinks were associated with higher RA risk, particularly among never-smokers. If further confirmed, these results could lead to novel mechanistic hypotheses and to simple prevention measures.
