Numerous studies have shown a link between low vitamin D levels and an increased risk of type 1 diabetes, but scientists are still studying whether low vitamin D levels actually cause the disease.
A recent study found that young people who have an adequate level of vitamin D, can reduce the risk of developing type 1 diabetes later in life by as much as 50 percent.Although the results are preliminary, the study provides solid evidence that vitamin D may protect against type 1 diabetes.
The study compared vitamin D levels in 310 people diagnosed with type 1 diabetes, and vitamin D levels in the second group consisting of healthy individuals.Scientists have determined the level of vitamin D by testing the frozen blood samples, which were taken before any of the participants had been diagnosed with diabetes.Experts have found that the level of vitamin D, which has been at a level of at least 75 nmol / L was associated with a 50 percent reduced risk of developing type 1 diabetes.

relationship of vitamin D and diabetes
Although certainly not been proven that vitamin D deficiency may cause diabetes, apparently, there is a correlation.Type 1 diabetes is an autoimmune disease in which the body's own immune cells attack the pancreas, the organ which produces insulin.Vitamin D has immunomodulatory properties, and low levels of vitamin D is associated with other autoimmune diseases and allergies.Vitamin D is essential for the immune system to function properly.If the body lacks of vitamin D, the immune system begins to attack its own human body.
source of vitamin D
recommended daily intake of vitamin D for adults aged 19 to 70 years - 600 international units (IU).People older than 70 years should take 800 IU.Sun, food and food additives - ways to get vitamin D. But vitamin D deficiency is widespread, because only a few foods contain vitamin D, and many people avoid sun exposure, or do not get it enough.
body weight can also affect the levels of vitamin D. In obese people lower circulating levels of vitamin D, than people with normal weight, since vitamin D is absorbed by fat.
Fatty fish such as salmon and tuna, eggs are foods with a high amount of natural vitamin D. fortified milk and cereals contain moderate amounts of vitamin D - read the labels to find the best.
Sun exposure is an excellent source of vitamin D, but it also carries a risk to health.People with fair skin may get about 10 000 IU for a 30-minute exposure to the sun, but many people take precautions to protect yourself from skin cancer by using sunscreen.In the winter months, especially in the northern regions, the sun is not strong enough to ensure the production of vitamin D.
Most people, especially in the winter months when sun exposure is minimal need to take supplements of vitamin D. Before you take the tablets, consult your doctorto check your vitamin D levels with a simple blood test.The doctor will determine whether you need supplementation of vitamin D and recommends the appropriate dose.
