Quite a few Dutch people suffer from a serious Vitamin D deficiency: no fewer than 40 percent of women over the age of fifty suffer from it.
Vitamin D is important for the structure and strength of bones and teeth. The body makes vitamin D when exposed to sunlight. The fact that so many people suffer from it is due to the fact that according to the Health Council quite a few people fall into a risk group: children (up to four years old), pregnant women, breastfeeding women, dark people, veiled women, women between 50 and 70 years and everyone above 70 all more risk. And everyone who does not see enough sun.
Vitamin D deficiency? These are the symptoms
The symptoms with a vitamin D deficiency can vary per person. The most common symptoms are:
According to Gert Schuitemaker, doctor of medicine, pharmacist and founder of the Orthomolecular Institute, the chance of cancer and autoimmune diseases reduced when taking vitamin D. The Health Council therefore advises risk groups to take daily nutritional supplements with ten micrograms of vitamin D.
However, Schuitemaker does not agree with this advice. In his report, he mentions that researchers believe that the government should increase the recommended daily allowance for vitamin D as quickly as possible. American researchers have calculated that on an annual basis there will be nearly seven thousand fewer cancer deaths if Dutch people lose 25 mcg of vitamin per day. Take D.
People who are between four and fifty years old do get enough according to the Health Council vitamin D from food and sunlight. Fatty fish, such as salmon and mackerel, is an important supplier of vitamin D. The recommended fish intake is twice a week at most. Furthermore, vitamin D is mainly added to margarine, baking and roasting products.
Inhibition of cancer
from research from KWF Kankerbestrijding It appears that a low vitamin D level increases the risk of colon, breast and prostate cancer by 30 to 50 percent. The chance of survival here is also lower with a vitamin D deficiency.
Laboratory experiments show that the growth of these forms of cancer is inhibited by a high vitamin D level. Finally, it appears that colon cancer is less common in people who have high levels of vitamin D in their blood.
Underestimation of vitamin D
According to Schuitemaker, a vitamin D deficiency has been underestimated worldwide for decades. In earlier research, he explained how people with a vitamin D deficiency can protect themselves against osteoporosis, cancer and heart and vascular disease. But possibly also against diabetes, rheumatism, multiple sclerosis, depression and tuberculosis.
