Women who drink one or more sugar-sweetened sodas a day are significantly more likely to develop rheumatoid arthritis (RA) than those who drink less than one soda month or none, according to a recent study published in The American Journal of Clinical Nutrition. The risk appears to be even higher for older women.
Rheumatoid arthritis is a systemic, autoimmune disease that causes inflammation leading to joint pain and damage, fatigue and other symptoms. It's believed to result from a combination of genetic and environmental factors, possibly including diet.
Because many studies have shown that sugar-sweetened soda is linked to obesity as well as type 2 diabetes and heart disease – all of which are more common in people with RA – the researchers wondered whether sugary beverages might play a role in the development of rheumatoid arthritis, too.
