Vitamin D Could Reduce Rheumatoid Arthritis Risk

V
itamin D may have beneficial effects on rheumatoid arthritis, according to a study published in the January issue of the journal Arthritis & Rheumatism.

" The study, conducted by American scientists, focused on 29 368 women, aged between 55 and 69 years, not suffering from this disease at its origin.

The researchers analyzed the presence of vitamin D in their diet, and taking nutritional supplements that same vitamin. 11 years later, they discovered that a significant taking vitamin D supplement was associated with a reduced risk of developing the disease.

Thus, women who consumed daily at least 400 international units of vitamin D supplement (10 micrograms per day) would reduce the risk of contracting the disease by 34%. However, research on the absorption of vitamin D during the simple diet have not yielded significant results.

Likewise, any food rich in vitamin D or calcium was strongly associated with reduced risk of developing rheumatoid arthritis.

According to researchers, this study is encouraging but further tests will be carried out to check the incidence of vitamin D on the risk of developing rheumatoid arthritis among older women.
