More than 80% of COVID patients vitamin D deficient: study

(nationalpost.com)

More than 80 per cent of hospitalized COVID-19 patients at a hospital in Spain had a vitamin D deficiency, according to a new small study.

Published by the Endocrine Society, Spanish researchers from the University Hospital Marques de Valdecilla looked at the vitamin D levels of 216 patients admitted for COVID-19 between March 10 and 31. They compared their vitamin D levels to those of a control group of 197 people of similar age and sex from a control cohort in the same geographical area. […]

Those most at risk of a vitamin D deficiency are those over 65 and people with dark skin. The darker your skin and the older you are, the less your body is able to produce the vitamin from the sun.

The Canadian government recommends 600 international units (IU) of vitamin D for adults every day. That increases to 800 IU for people older than 70 years, and 400 IU for infants.

You can also get vitamin D from what you eat, but diet may not be enough, which is why sun exposure or supplementation may be needed. But since the winter brings with it less sunlight, it may be helpful to focus on food sources of vitamin D such as milk, orange juice, cheese, and yogurt. The only natural food sources of vitamin D in Canada are fatty fish and egg yolks.

This sounds like as good a reason as any to not work in an office, factory, mall, or any building capable of having rooms without windows that face outside.

I think it also means that is about as COVID-immune as one could hope to be, primarily because of how much time he spends outdoors 😬
