Been closely vitamin D and discover how it can help keep you healthy longer. The summer is about to end and soon winter will be here and the sun goodbye, at least for a while. Yes, because after years of claims about sun damage it has now emerged a very different picture. The burning under the rays undoubtedly accelerates skin aging and increases the risk of developing melanoma. But exposing yourself to sunlight is essential to your health.
I have spoken many times of vitamin D solitariness what this substance (to be precise, this hormone) is essential to regulate the immune system, prevent heart disease, to control cell replication, and even make us less vulnerable to mood swings and to depression. Furthermore, vitamin D favors the absorption of calcium in the gut, calcium vitamin K2 that then will set in bones by regulating the activity of a specific protein called osteocalcin. The action regulating the immune system is very powerful, so much so that vitamin D becomes very useful in dealing with complex diseases such as multiple sclerosis and other autoimmune diseases.
Vitamin D is produced by exposure of the skin to sunlight while food intake is poor. Clearly, in many parts of the world it is little sunlight for many months a year. In addition, the modern workplace and the clothes make it increasingly difficult for our body to produce sufficient amounts of the vitamin. Today we know with certainty from numerous studies that vitamin D deficiency is widespread and, with all due respect to those who remain opposed to supplements, assume an additional quantity is fundamental to health. A paper published in April this year indicates that vitamin D values of 40ng / ml or more are associated with a 67% reduction in the risk of developing cancer over the next 4 years.
For this reason, the authors suggest a revision of the standard values of this vitamin, which usually stood between 20 and 100ng / ml. This is an issue, which I have spoken often and stretch extensively in my course potentiality nutrition.

What does it mean standard value? It corresponds to the optimal value, what gives us greater security not to get sick? Or simply indicates the level below which we run a greater risk of being in shortage? Or, simply corresponds to the average values in the population that refers to a specific analytical laboratory?
The vitamin D deficiency is widespread and, with all due respect to those who remain opposed to supplements, assume an additional quantity is critical to the health.
Indeed, for all the possible measurements in medicine you are never defined the optimal values but the minimum and maximum thresholds above which increases the risk of problems. Everything in between is considered “normal”, whatever that meant. If the value range is rather narrow the mechanism might work. But if, on the contrary, is large it becomes very difficult to understand that we are provided.
Today it is crucial to define the optimal values of the parameters that we measure to ensure that we remain faithful to a full concept of health. In the case of vitamin D these amounted to around 50-70ng / ml.
The authors believe that the control and whether vitamin D supplementation is a fundamental aspect of a preventive approach to cancer.
That’s why, in addition to enjoy the last sunny days, I suggest you act now and follow 3 simple steps …
- Ask the doctor to make the dose of 25-OH vitamin D with a simple blood test;
- If the result indicates a value lower than 30NG / ml or between 30 and 40 six candidate to a supplementation of vitamin D;
- Having decided on the appropriate dose with your doctor, repeat the test at a distance of a couple of months to check the degree of improvement.
