What is vitamin D? Thanks for asking.
Vitamin D was discovered in 1922 by American biochemist Elmer Macollum, who was nicknamed Dr. Vitamin by Time magazine.
He found that cod liver oil could still prevent rickets in rats despite its vitamin A being being removed.
From this observation he deduced that it contained a different substance which he called Vitamin D.
A sufficient quantity of Vitamin D is necessary during early childhood years in order to prevent rickets.
In adults it protects against osteoporosis and the deterioration of bone tissue.
It also plays an important part in preventing breast cancer and colon cancer.
Vitamin D deficiency increases the risk of hypertension and cardiovascular diseases.
According to a study published in the American Journal of Clinical Nutrition, over 1 billion people worldwide are vitamin D deficient.
In May 2020 an American study suggested that vitamin D deficiency could increase the risks of complications associated with COVID -19.
This was based on data from countries severely affected by the pandemic, like China, France, Germany, Italy and the United States.
According to a Dutch study, another vitamin might give you an advantage in fighting the virus and that's vitamin K.
COVID -19 causes coagulation of blood and degrades elastic pulmonary fibers, whereas vitamin K, consumed with food, participates in the production of proteins which regulate coagulation.
How do we produce or find vitamin D then?
Vitamin D can come from two sources.
A portion of it, about 20%, comes from food, especially products of animal origin and those containing fat.
The other portion is synthesized by your body at skin level, under the effect of ultraviolet light, and then stored in fat, muscles and adipose tissue to be used during winter.
That means our body is capable of producing it, but for that it needs to be exposed to the sun. However staying in the Sun for too long is dangerous and will do you more harm than good.
Production of vitamin D stops by itself very quickly.
Ten to fifteen minutes of sunbathing with half your body exposed, your arms and your legs, should do it.
But how does sunblock work then?
Sun cream simply protects your skin especially from skin cancer but it does not prevent production of vitamin D in your body.
It would be a shame to remain vitamin D deficient in the full blaze of It should be noted that the further north you go, the more important it is to make sure you get enough vitamin D.
Some countries even add nutritional supplements based on vitamin D to baby formula.
People above 65 are also recommended to take nutritional supplements based on vitamin D.
What about skin colour?
Does that impact our ability to produce vitamin D?
Our complexion adjusts to a specific environment, so darker pigmentation reduces the skin's capacity to produce vitamin D, requiring longer exposure to the sun. The opposite is true for people with lighter skin.
With summer just beginning, what better time to top up with a healthy dose of vitamin D?
In moderation, of course.
There you have it, now you know what vitamin D is.
