Vitamin D Status In The United States, 2011–2014, American Journal of Clinical Nutrition, 10 May 2019
First, the Vitamin D situation is not getting worse, it’s getting better:
This report provides the most recent estimates for the US population of the prevalence of at risk of deficiency or inadequacy of vitamin D.
The prevalence of at risk of vitamin D deficiency in the United States remained stable from 2003 to 2014; at risk of inadequacy declined.
And older adults (aged 60yrs or older) have a LOWER risk of Vitamin D deficiency (2.9%) and inadequacy (12.3%) than younger adults. Everyone older than 11 years (aged 12 to 59) have a HIGHER risk. Those aged 20-39 have the highest risk for deficiency (7.6%) and inadequacy (23.8%).
Researchers at Northwestern University are saying that Vitamin D deficiency is more prevalent in “elderly populations.”
NU Researchers Discover Strong Correlation Between Vitamin D Deficiency And Covid-19 Mortality Rates
The abstract for their study says that Vitamin D insufficiency is greater with “advanced age.”
Vitamin D Insufficiency Is Prevalent In Severe COVID-19, 28 April 2020
If it is true that Vitamin D deficiency or inadequacy increases the risk for dying of COVID-19, you would expect people aged 20 to 39 years to be more affected, since they have the highest prevalence of deficiency and inadequacy. But…
These researchers are perpetuating the myth that people’s health (in this case, Vitamin D status) declines based merely upon age. Discrimination against people based upon their age is ageism. Just as societies should not tolerate racism, they should not tolerate ageism.
