Especially in winter, many people have too low a vitamin D level. Between October and April, the sun's UV-B radiation is no longer enough to make vital vitamin D..

"Vitamin D is involved in the development or prevention of almost all chronic diseases," says Professor. med. Jörg Spitz, President of the Society for Biological Cancer Defense e. V. (GfBK). Vitamin D has an anti-inflammatory and immune-stabilizing effect and can protect against cancerous relapses and metastases in cancer patients. The company therefore recommends testing vitamin D levels in the blood during the cold season and providing blood levels of 30 to 50 ng / ml.

Around one third of the German population is poorly supplied with vitamin D, according to the nationwide "Study on adult health in Germany" (DEGS) in the summer of 2017. You have a serum concentration of < 30 nmol/l 25-Hydroxyvitamin-D (= weniger als 12 ng/l). Nur knapp 40 Prozent sind ausreichend versorgt, heißt es im 13. DGE-Ernährungs-

"Especially cancer patients should at least in the winter in addition vitamin D supplements with 2000 I.E. (International Unit) daily, "says Dr. med. György Irmey, medical director of GfBK. About the food, such as high-fat fish or dairy products, people can cover at most 20 percent of the need for the "sun hormone". Even a Christmas holiday in the sun is not enough for the rest of the winter, so investigations.

Shield against cancer and other diseases
The beneficial effects of vitamin D have been confirmed by numerous studies. It has an anti-inflammatory and immune-stabilizing effect. A good vitamin D supply can protect against re-cases and metastases, such. B. the review of the German Cancer Research Center noted (Maalmi H / Eur J Cancer 2014). This has been proven above all for breast and colon cancer patients. "People with high levels of vitamin D in their blood are less likely to develop bowel cancer by as much as 40 percent," says Professor Spitz, citing a large study involving more than half a million people from ten Western European countries (Jenab et al / British Medical Journal 2010) ). But against other diseases such as rheumatism, bone diseases such as osteoporosis, myocardial infarction vitamin D has a preventive effect.
