(NaturalNews) A growing body of research suggests that not only may vitamin D deficiency be a risk factor for rheumatoid arthritis, it may also make rheumatoid arthritis patients significantly more susceptible to cardiovascular disease.
Rheumatoid arthritis is an autoimmune disorder that occurs when the body’s immune system attacks its own tissues, particularly the joints. Because vitamin D is known to play an important role in regulating the immune system and has been specifically linked to the occurrence of other autoimmune disorders, many researchers have long suspected that deficiency might increase the risk of rheumatoid arthritis.
Confirmation of this link came in 2010, in a study published in the journal Environmental Health Perspectives that looked at the effect of environmental factors on rheumatoid arthritis risk. The researchers found that women living in the Northeast were significantly more likely to develop the disease.
