This map describes causes of death that stand out as more common than you would expect compared to national averages. Most of them have a moderately obvious connection. If you live in Alaska, you’re more likely to die flying your plane or drowning when your crab fishing boat sinks. If you live in Miami or Key West, you die from HIV. If you live in coal country, you die from black lung disease. North Carolina gets nutritional deficiencies (but it is only 103 people, so don’t read too much into it). The Coastal plain of Eastern NC is largely occupied by poor black farmers who eek out a marginal living by growing peanuts.
Diets high in corn (corn bread, hush puppies, grits) can cause Pellagra, which affected millions of poor Southerners (mostly blacks) before the connection was made and the Yankees “forced” flour mills to fortify wheat flour with Niacin
Slightly related, my recent trip to the dentist wound up with (more or less) “I don’t want you as a patient, but I’m not allowed to say that”. Things immediately went South [interesting expression] when I stated that I believe vitamin D deficiency is a cause of some of my problems. She immediately got a “oh, you’re one of those wackos” look.
Black Americans live substantially shorter lives in the United States. There is a pretty direct reason for that, particularly blacks that moved North during the great Northern Migration. Because blacks have dark skin (duh!), the melanin blocks the creation of adequate Vitamin D, especially with shorter days, decreased time outdoors and low intensity of the sun.
Most people fend off Vitamin D deficiency by drinking fortified milk, but most black people are lactose intolerant. Adults being able to consume milk without getting sick was a genetic mutation primarily to people who settled in Europe.
As that abstract hints, one of the consequences of melanin blocking Vitamin D synthesis is autoimmune disease. Lupus is a common autoimmune disease that affects primarily blacks, Native Americans and Asians – but few Europeans, which coincidently are the same groups that can’t digest milk sugar. The issue isn’t the lactose, but that we don’t fortify other dairy products like cheese with Vitamin D. Some orange juice has D added, but not most.
If you still think I’m a kook,
