vitamin D would protect against autoimmune diseases

Type 1 diabetes, multiple sclerosis, rheumatoid arthritis, lupus… autoimmune diseases affect about 5 million French. Researchers at Brigham and Women’s Hospital may have found a way to protect against them pathologies that “attack” the body. Use vitamin D and omega 3 would reduce the risk create, according to their new work published in the scientific journal BMJ.

Autoimmune disease: Vitamin D may reduce risk

This was followed by a study called VITAL more than 26,000 men and women over the age of 50 more than 5 years. One group received a daily dose 2000 international units of vitamin D and omega 3, another vitamin D with placebo, the third had fish oil supplements and placebo, and the last had placebo only.

“Considering the benefits vitamin D and omega-3 to reduce inflammation, we were particularly interested in whether they could protect against autoimmune disease,” said study co-author JoAnn Manson.

In their work, researchers found that people who took vitamin D daily for more than 5 years had an increased risk of developing autoimmune diseases. decreased by 22 percent compared to those who did not. Supplement with omega 3 fatty acids with or without vitamin D, in turn, decreased the incidence of autoimmune diseases 15 percent

“Autoimmune diseases are common in the elderly and have a negative impact on health and life expectancy. So far we’ve only had there is no proven way to avoid themand now we have it for the first time, said lead author Jill Hahn, a Brigham PhD student. – It would be interesting if we could continue to check the same preventive effect in younger people“.

Vitamin D: Need New Recommendations?

The 50-year-olds who took part in the study occupied up to 2000 international units (IU) of vitamin D and 1000 TVs aboutOmega 3. This dose is 2-3 times higher than current recommendations (600 IU of vitamin D for people under 69 and 800 IU for people over 70).

Karen Costenbader, chief of Rheumatology, Inflammation and Immunity at Brigham, explains, “This is the first direct evidence that a daily dietary supplement can reduce the incidence of autoimmune diseases and appears to a more pronounced effect after two years of vitamin D supplementation. We hope to improve and extend our findings and encourage professional societies to consider these results in the development of future guidelines for the prevention of autoimmune diseases in the elderly.

But be careful, don’t rush to the pharmacy to buy boxes of nutritional supplements. An expert interviewed by CNN warns that “everyone should first consult your doctor before taking 2000 international units of vitamin D in addition to all that is taken.” She clarifies: “there are certain health problems, e.g kidney stones andhyperparathyroidism (increased calcium) that really shouldn’t require vitamin D supplementation.”

Furthermore, the study could not determine which many existing autoimmune diseases benefit most from the protective effects of these elements. The researchers agree that further research is needed to distinguish and ensure that the preventive effects apply to younger people as well.
