It sounds like a football match. New reports from an Israeli health fund and medical academics have ‘shown’ that a lack of Vit. D correlates to getting COVID-19 and being hospitalized with it.
First warning sign: The reporter asks not one critical question. But she does convey how important this finding and these Israeli scientists are.
Second warning sign: It is unknown how the vitamin should protect us.
Third warning sign: This is not a proper statistical study–only an accidental statistical correlation. Which could be on the level of: We see fewer storks, fewer babies are born, so, babies are brought by storks. They adjusted the finding for “age, gender, socioeconomic status and chronic, mental and physical disorders.” But not for things that are relevant (see below).
Fourth warning sign: This is linked to food. Doctors know zero about food.
Vitamins are essential molecules that the human body cannot build. That means that we either need to eat it or must eat something that the body can modify to create that vitamin.
Vitamin D is a very potent molecule that is involved in many biochemical reactions in the body, probably most of them still unknown. One function could relate to immunology, but there is much more.
What is known is that no diet contains Vitamin D. We all need to eat it as a supplement. The authorities in rich countries add Vit. D to milk products.
But that means that people who are allergic to or dislike milk and milk products don’t get their D. Among them are Yemenite and many other Mizrachic Jews, who may eat meat daily and not even own one dairy spoon or plate (or only a few for the baby or the cat). After meat, they need to wait some 6 hours before they are allowed milk products and, therefore, may never consume any. Sunlight on our skin (and mushrooms) may make Vitamin D from a precursor but, many religious or traditional Jews do not expose their skin. Even their nose may fall under a big hat.
On the other hand, many religious Jews learned much too late the science behind corona, and got infected at Purim and Lag ba-Omer parties and now in cramped child-rich households from their family members.
So, of course, we see more COVID-19 infections among those with little Vitamin D. The correlation has nothing to do with Vit. D protecting us.
