What we need to learn – ASAP about Covid-19.
About the author. Stephen Cherniske taught Clinical Nutrition at two southern California universities and directed the nation’s first FDA-licensed clinical lab specializing in nutrition and immunology. He and his wife, a board-certified Family Medicine MD, provide information and insights at My2048.com.
A 101- year-old man from Italy, born during the Spanish Flu Pandemic, has beaten coronavirus. He was released from hospital and is in good spirits.
In Washington State, where I live, the numbers tell another story. If you factor out the deaths occurring in two nursing homes near Seattle, the case/fatality ratio goes from 4.5% to approximately 1%.
And then there’s news from Iceland where fully half of those who tested positive for COVID-19 are asymptomatic, and the other half, according to health authorities, display “very moderate cold-like symptoms.” Only 30 have been hospitalized out of the country’s 1,086 confirmed infections, and there are no deaths as of the time of this post.
My point is that we need to be gathering in-depth information about people who test positive and have no symptoms, as well as people who tested positive, got sick and recovered. This information would be compared to age-matched individuals who became severely ill or who died. In other words, we need to look for the factors that protect people from this virus.
If you know me or have read any of my books, you know that my first biomarker would be serum DHEA sulfate (DHEAS). That stems from a conference I attended in Milan 25 years ago where an Italian gerontologist named Giovanni Ravaglia pointed out the remarkable correlation between successful aging and one’s DHEA level. That was followed by hundreds of studies showing the role that DHEA plays in immunity, muscle mass, bone density and the risk for virtually every major cause of death. You can download my e-book, The Case for DHEA for free at My2048.com.
My next biomarker would be Serum 25-hydroxy vitamin D. That’s because vast numbers of adults in North America have very low levels of vitamin D, and multiple studies with thousands of men and women, have found that low levels are associated with not just the risk for osteoporosis, but cancer, cardiovascular disease, infection and death from any cause.
Next, serum zinc, another nutrient critically important for immunity, and finally, serum ferritin, for the opposite reason. People eating a Western diet tend to have low levels of zinc, but high levels of iron derived primarily from red meat. Menstruating women lose iron every month, and thus do not accumulate excess iron. But after menopause, they have the same increased risk for infection as men. That’s because all pathogens, including bacteria and viruses, need iron to proliferate, and excess tissue levels worsen infection.

One thought on “What we need to learn – ASAP about Covid-19”
I get annual full blood tests from Life Extension. Vit D and DEAH-S are fine.
which test reveals iron and what is a good level?
Is there a test for zinc? We have zinc tabs from Life Ext and don’t take them because they seem to cause a problem and are hard to tolerate. What do you recommend for zinc supps? Or, is it best load up on zinc only when sick? thanks in advance,
PS: Thank you for getting this information out there as best you can. My pet peeve with Fauci etc. is that there is little to no acknowledgement of Vitamin D in mainstream media. It is all just Vaccine, Vaccine, Vaccine which makes me wonder if he/them can be trusted to actually have the people’s best interests at heart.
