A new study in the journal Arthritis and Rheumatism suggests that moderate consumption of alcohol may help delay the progression of rheumatoid arthritis (RA).

According to Reuters, researchers followed 2,900 adults with RA for an average of four years. Over the course of the study, participants had their hands and feet x-rayed at least two times to evaluate joint damage.

The study showed that light-to-moderate drinkers showed slower progression in joint damage compared with non-drinkers. Heavy drinkers, however, showed the greatest progression of the disease.

In addition, the protective effects of moderate drinking were stronger in men than in women.

Researchers say that previous animal studies have suggested that moderate alcohol consumption may inhibit arthritis, possibly by reducing inflammation. On the other hand, heavy drinking may promote inflammation.

The arthritis foundation reports that 1.3 million Americans suffer from RA. The cause of this chronic disease is unknown.

Among the alternative therapies believed to help ease the pain of RA are tai chi and acupuncture. The Mayo Clinic says that nutritional supplements containing fish oil and plant oils such as evening primrose, borage and black currant may also help alleviate RA pain.
