The lack of vitamin D, also called "sun vitamin" is quite common, especially in the winter. The risks we are exposed to because of the lack of this nutritional substance in the body are worrying.
"Deficiency of vitamin D, especially at an advanced age, can lead to osteoporosis and osteomalacia (decalcification of the bones)," points Dr. Lona Sandon of Southwest University of Texas, Dallas. It may also increase the risk of developing cancer and even tuberculosis, Harvard experts note.
Here's what diseases can occur because of vitamin D deficiency:
One of the most important functions of vitamin D is to maintain bone density together with calcium, so lack of it can lead to bone fragility. Lack of vitamin D can also cause severe back and joint pains.
Vitamin D is not a vitamin, it is more like a hormone. Instead of being produced by the thyroid, it is produced by the skin when exposed to the sun. It is necessary for many processes in the body.
Cortisol needs large amounts of vitamin D to be produced. Insufficient amounts of cortisol produce pain and inflammation of the joints. This is why cortisone treatment is needed to relieve pain.
Back pain is related to lack of vitamin D and vitamin B12, B5 and B6 deficiencies.
Another important role of this vitamin is to decrease inflammation in the lungs and increase the production of an anti-inflammatory protein.
Lack of vitamin D is associated with increased blood pressure and cholesterol.
A group of experts has noticed that vitamin D also influences mood. In a study in which some volunteers received vitamin D supplements for five days in winter, and another group did not. Finally, those who took the supplements recorded a stronger emotional state than the other participants.
"Headaches occur in people with vitamin D deficiency because they sleep poorly and suffer from depression. Lack of sleep, associated with pain caused by lack of vitamin D, contributes to headaches, "Dr. Doina Catrinoiu
Type 2 diabetes
Scientists have noticed that there is a link between the risk of developing type 2 diabetes and the vitamin D nevi. This influences the body's sensitivity to insulin.
So how do we know we do not have enough vitamin D in the body? What are the symptoms? How can we adapt our diet to benefit from the vitamin D effects, so that we have a strong bone life?
As for the symptoms, there are a few that the adult presents, such as tetanus or – popularly called – crèches, which are a sign of vitamin D deficiency and normally show a lack of calcium. There is also spasmophilia, which is often overdiagnosed.
Generally, there is a vitamin D deficiency among the population because of the diet. Romanians eat very little fish. The most important source of vitamin D is fatty fish – salmon for example (although any type of fish contains vitamin D). Other foods that can help us in the vitamin D buildup are beef, cheese, egg yolk. However, the most important source and best absorbing calcium is fatty fish, fish liver. "There is such an idea in us that fatty fish grew, but then what about fatty meat? The fatty fish is very good, rich in free radicals, a very important and very healthy source for the body. There should be a clearer education of the population in terms of fish consumption. And in adults and children, "says Dr. Doina Catrinoiu.
