Vitamin D plays a major role in bone growth and mineralization. But according to Belgian doctors, it also helps to fight the coronavirus by supporting the proper functioning of our immune system. While the major source of vitamin D is still exposure to light, during periods of confinement it is better to eat foods rich in vitamin D. We'll tell you which ones.
The main function of vitamin D is to promote the absorption of calcium and phosphorus by the intestine and thus, indirectly, to participate in the optimal mineralization of bones, cartilage and teeth. But according to two professors from the University of Liège (Belgium) quoted by the RTBF, vitamin D is also a means of protecting against coronavirus because it helps our immune system to fight respiratory infections.
The researchers refer to a meta-analysis published a few years ago in the British medical Journal, which showed that vitamin D supplementation had a protective effect against acute respiratory tract infections, particularly in people who were severely deficient in this vitamin.
Our bodies are known to be able to synthesise vitamin D themselves if they are sufficiently exposed to the sun: under the action of UVB radiation, they convert a cholesterol derivative into vitamin D. But in this period of confinement, only those who have a garden or a well-oriented balcony can benefit from daily exposure to the sun. That's why it's important to rely on dietary sources of vitamin D.
