Vitamin D, also known by the name sunshine vitamin, is made by the body as a response to the sun exposure.

Also, you can consume this vitamin in supplements and foods. Despite its name, this vitamin is actually a pro-hormone and not a vitamin. Vitamins are nutrients which cannot be made by the body. For that reason, you need to take them through diet.

On the other hand, this vitamin may be synthesized by the body when the sunlight hits the skin. According to estimations, sensible sun exposure from 5 to 10 minutes for 2 to 3 times on a weekly basis allows people to make sufficient amount of vitamin D.

However; you should know that this vitamin breaks down quickly meaning that is low, particularly in winter. But, there is more in this vitamin than we were aware of. One new study confirmes that.

The Study

Recently, the journal Diabetes published one study about the importance of this vitamin. According to this study, kids who are susceptible to type 1 diabetes might lower their risk of the condition. That is possible if they get sufficient amounts of vitamin D.

The researchers found that kids with low blood levels of this vitamin were more likely to have islet autoimmunity. This is in comparison to the kids with higher vitamin D levels.

As a matter of fact, islet autoimmunity is a process in which the immune system attacks by mistake the cells which produce insulin of the pancreas and leads to type 1 diabetes.

According to Jill Norris, the lead author of the study, Ph.D. of the Colorado School of Public Health and her colleagues this study is the first which found that higher vitamin D levels might help stop islet autoimmunity.

When you have type 1 diabetes, that means that your body fails to make enough insulin. Insulin is a hormone which regulates the blood sugar levels.

In this condition, the immune system attacks the pancreatic cells by the name Islets of Langerhans, known as islets. These are actually the clusters of the cells which contain beta cells. Their function is to detect sugar in the blood and release it when necessary.

As a consequence of the immune attack on islets, the beta cells cannot make enough insulin. That leads to too high blood sugar levels.

Type 1 diabetes might develop at any age. However, onset is common in childhood. The American Diabetes Association notes that 1.25 million adults and children in the US have this type of diabetes.

The Long-Term Controversy

According to previous research, low vitamin D levels might raise the risk regarding type 1 diabetes. Due to these studies, the scientists have been investigating whether the higher levels of this vitamin might have a preventive effect when it comes to diabetes type 1.

However, the studies came with conflicting results. In addition, you should know that vitamin D is part of certain foods such as egg yolks, cheese, and fatty fish.

Dr. Norris together with her colleagues for the latest research set out to find out more about the relationship between type 1 diabetes and vitamin D. The main focus of the study was the find out whether levels of vitamin D in childhood impact islet autoimmunity.

Lower Risk of Islet Autoimmunity

This study involved around 8,676 kids with genetic risk for obtaining type 1 diabetes. They took blood samples from each kid every 3 to 6 months starting from infancy to 4 years. They used the same samples to recognize islet autoimmunity and vitamin D levels.

Around 376 kids developed islet autoimmunity, and the vitamin D levels of these kids were compared with the vitamin D levels of the 1,041 kids who did not develop diabetes type 1.

The researchers found that kids with a variant in the receptor gene of vitamin D, higher levels of vitamin D during childhood and infancy linked to lower risk of having islet autoimmunity.

According to the researchers, the study cannot prove the effect and cause between the higher levels of vitamin D and the lower risk of islet autoimmunity. Also, the scientists note that there is a need for further studies.

To sum up, this study notes that high amount of vitamin D can prevent type 1 diabetes in kids who are genetically susceptible to this condition. If you find this article useful, share it with your friends and family.
