Thats why the cholesterol bashing thats occured by governments public health campaigns is/Has bordered on criminal. Cholesterol is critical for vitamin d production. The racial discrepancy is due to the mitochondrial haplotypes and our overall evolution. Light skin adapted for low light colder conditions, so absorbs more vitamin d in low light. Darker skins, less evolutionary adapted for cold dark climes. Need lots more sunshine to make the same levels of vitamin d. So, take darker skin, add sun block, place in cold climates above certain latitudes and you have much worse covid outcomes, without even adding comorbities in.
