A survey conducted by Swedish scientists suggests that the consumption of five glasses of wine per week reduced by 50% the risk of rheumatoid arthritis, indicates a study published in the Annals of the Rheumatic Diseases.
The team, from Karolinska University, examined 2750 volunteers in two separate studies.
The researchers assessed the genetic and external factors that could contribute to the onset of the disease. The participants answered questionnaires on lifestyle and have them collected blood samples to assess the genetic factors.
Previous studies have pointed to the link between moderate consumption of alcoholic beverages and a reduction of other inflammatory processes, as in the study of cardiovascular disease. The reason for this, however, is not yet clear.
The leader of the research, Henrik Kallberg stressed that one of the most important discoveries was that smoking contributes significantly to increase the likelihood of developing rheumatoid arthritis.
