A new study from the United Kingdom, published in the Journal of Autoimmunity, finds that vitamin D may prevent inflammatory diseases such as rheumatoid arthritis. This vitamin strengthens the immune system helping prevent the body from attacking healthy cells and causing autoimmune conditions of this kind.
For the study, a team of researchers analyzed blood samples and joint fluid samples from rheumatoid arthritis patients.
Study author Dr. Louisa Jeffery from the University of Birmingham says: “Our research indicated that maintaining sufficient vitamin D may help to prevent the onset of an inflammatory disease like rheumatoid arthritis.”
Vitamin D deficiency and insufficiency is now a global public-health problem affecting an estimated 1 billion people. Vitamin D deficiencies are connected to the increased risk for Alzheimer’s disease, diabetes, osteoporosis, and heart disease. Moreover, people with a diagnosis of prostate or breast cancer have lower chances to survive than those with normal levels of vitamin D.
Here are 10 categories of people that are in risk group:
- Adults older than 55.
- Office workers.
- People with darker skin.
- Inflammatory bowel disease patients.
- Vegans and vegetarians.
- People with a high body fat percentage.
- People taking medications such as corticosteroids, weight-loss drugs, and the cholesterol-lowering drug cholestyramine.
- People with constant joint and muscles aches.
- People suffering from depression.
- People suffering from chronic headaches.
A clinical review, published in The Journal of the American Osteopathic Association, finds that about 1 billion people around the globe may experience vitamin D deficiency or be insufficient of vitamin D levels because of chronic disease and improper sun exposure connected to sunscreen use.
Moreover, the study found that 95% of African American adults may be vitamin D deficient or have insufficient levels of the vitamin.
A researcher on this study Kim Pfotenhauer, DO, assistant professor at Touro University, explains: “People are spending less time outside and, when they do go out, they’re typically wearing sunscreen, which essentially nullifies the body’s ability to produce vitamin D. While we want people to protect themselves against skin cancer, there are healthy, moderate levels of unprotected sun exposure that can be very helpful in boosting vitamin D.”
A new research, executed by the scientists from the Harvard-affiliated Hebrew Senior Life and the University of Massachusetts, shows that a combination of vitamin D supplements and certain dairies can protect seniors from age-related bone loss.
The study included participants who have been enrolled in the long-term Framingham Study, which began in 1948. The study followed the health and habits of residents of the town of Framingham, Massachusetts, USA.
The lead author Shivani Sahni of the study says that it is significant because it looked at dairy products other than just milk, and it also clarified that the association of dairy foods with bone density is dependent on adequate vitamin D intake.
Vitamin D has several important functions. Perhaps the most vital of them are regulating the absorption of calcium and phosphorous and providing normal immune system function. Getting sufficient amount of this vitamin is crucial for normal growth and development of bones and teeth. It is also important for resistance against certain diseases.
If you don’t receive enough vitamin D, you may develop bone abnormalities such as soft bones or fragile bones. Here’s the list of products that contain this vitamin naturally, or are fortified with it.
- milk (fortified);
- egg yolks;
- orange juice (fortified);
- plain yogurts (fortified);
- cereals (fortified);
