Question for people who know science.
-
@davidnjoku I was going to write about haplogroups, but your other reply made me think about impressions of medical commonality despite underlying genetic diversity ...
How has the diaspora affected that diversity? Do French Black people and British Black people share the same percentage of medical predispositions? How does that compare to the Americas?
Is there any noticeable difference between populations descending from colonial emigration and those who suffered forced relocation?
@alltherum Haven't thought about that, but that would be a very interesting thing to find out. I don't know for sure, but I imagine that a good proportion of the Black people in the Netherlands come from South Africa and from Suriname, and not as many from Nigeria and Ghana as in the UK. What difference does that make, I wonder?

Question for people who know science.
I know that race is a social construct. The fact that I'm 'Black' has no meaning beyond my melanin levels. It doesn't, for instance, make me a better rapper than you. Culture might, but melanin doesn't.
So why are there medical differences between races? Black women have more fibroids, & have their babies a week earlier than white women. And Black men are more prone to type 2 diabetes.
Why's that? Culture? Racism? Something else?
@davidnjoku i should have read the thread first
very interesting stuff -
@davep That's a good point. But there are a billion Black people, and we're genetically more diverse than all of the rest of the world put together, so it's a bit strange (to my non-scientific mind) that there'll be traits that affect all of us.
@davidnjoku I can't really talk about these traits, as I don't know enough about that. But are you sure they affect black people (globally) or just African Americans? Because that's a huge difference if you consider genetic diversity. And then social factors come into play as well additionally.
-
@davidnjoku @PurpleJillybeans I’ve thought about this a LOT, and I have zero answers for you. Even more fascinating to me is that are some medical markers only in African Americans. How did that happen in the last 600 years?
@topher1kenobe I didn't know that about African Americans. That's just crazy.

@weddige I don't know.
When I lived in Nigeria, no one talked about things like that, cos we were all Black. But here in the UK, we do hear about the differences between the races a fair amount.

@davidnjoku In the States, the big concern is heart disease and infant mortality. There's been a great deal of research done concluding that, in those cases, it very specifically is racism-related. Specifically, systemically induced stress.

@davidnjoku AFAIK the diabetes thing specifically came from a sample that looked exclusively at black US americans which is a genetically much more homogenous group that black people in general. You see those kind of medical differences show up along all kinds of endogenic groups, 'race' just happens to line up with that.
(And also, sometimes whites are just the odd ones out and it's actually not black people have more X but rather white people have *less* X.) -
@GavinChait That makes sense. About a quarter of all Nigerians have the sickle cell trait. Other African countries, not so much.
So it's just a useful shorthand to say something like sickle cell affects Black people? Instead of it affects people from the mosquito-infected rainforests near the equator?
@davidnjoku pretty much. Sickle cell even reduces malaria effects, so there's an advantage to having it that happens to come with a lot of negatives.
The challenge with ethnicity-associated disease is that it's correlated with other things. People who all migrated from the same village & brought with them an otherwise rare condition. Or a regional genetic survival trait that becomes harmful as conditions change. Just because it is common within an ethnicity doesn't mean •everyone• is effected.

@alltherum Yes, that happens here too, but to a lesser extent, I believe.

@davidnjoku @davep maybe that's the moment to bring someone like @mekkaokereke into the discussion

Great questions!
The short answer is that things like having babies a week earlier doesn't affect Black people more. It doesn't. It affects *Black people from a tiny part of West Africa* more.
Medical textbooks tested Black American people who are almost all West African (Nigeria, Ivory Coast, Ghana) or southwestern African (Angola).
They just say that Black people have this, ignoring the fact that most of the human genetic diversity on earth is in Africa.

I think diet is a lot of it. Trad foods of every culture carry various benefits - and detriments. Animal fats, bread & corn meal...
Diabetes is a tricky one. The corporate controlled medical establishments tells diabetics they can keep on eating carbs when they should avoid all carbs like the plague.
And men avoid doctors.
Yes, there is absolutely a big problem with racists who go into medical care to get rich or have stable jobs, and not because they want to help people.
YMMV

@davidnjoku also, imagine a founder effect... An initial group of Nigerians arrive in the UK & - this is where racism comes in - Britain is its normal, welcoming self, so the Nigerians form their own community. New Africans arrive from elsewhere on the continent & look for somewhere welcoming. The Nigerian community becomes a pan-African community. A few generations later & a Nigerian-Malian has sickle cell. Apply that to any other relatively distinct group of migrants & off you go.

@davidnjoku I honestly don't know if this counts as "knowing science", so please feel free to disregard this reply if it does not. But for what it's worth I inhabit a culture that actively rejects the term "Rasse", when applied to people, as unscientific. If you read German (or have access to a good translator, human or machine), perhaps you find this Wikipedia article insightful.

@davidnjoku @PurpleJillybeans yeah, I’m trying to remember something I read on the internet 20 years ago, so do NOT quote me, but I think African American men have a higher incidence of heart disease. So that’s a pretty specific group. I’m really curious why.

️Do "Black" people have higher BMI? Due to higher bone density and higher skeletal muscle mass? Or do Asian people? Is that why Black people are over represented in the NFL?
The answer of course depends on which Black people and which Asian people we are talking about.
Asian people are *the most* overrepresented in the NFL, and it's not remotely close. The strongest *officially measured* NFL player is Asian. Stephen Paea. The strongest *unofficially measured* NFL player is West African. Larry Allen.
Think of how silly it would be to use Stephen Paea, Haloti Ngata, and Troy Polumalu as samples, and infer population characteristics for every Chinese citizen. That's what US medical textbooks making predictions about "Black" people do to all Africans.

Attached: 3 images Now I need you to understand something before we go further: Race isn't real. Racism is. "Black" people have naturally higher BMI. I put Black in scare quotes, because the 1.5 billion Black people don't have higher BMI. Black people *from a tiny part of West Africa* have higher BMI.🙋🏿♂️ Just like white people from a tiny part (Iceland) have higher BMI. Just like Asian people from a tiny part (Samoa). Every "race" has a tiny population with slightly more height, denser bones, and more muscle.

Stephen Paea for those unaware.
There are ~8 billion people on earth. All of us have different bone circumferences, bone densities, muscle masses, muscle densities, internal organ sizes, propensity to build and retain muscle, percentage of fast-twitch muscle vs slow twitch, etc.
Of all 8 billion humans, Stephen Paea is an *extreme outlier* on the combination of all of these. To put numbers on it, in the top millionth of a percent. Not a typo.
He is 100% Asian, descended from indigenous Taiwanese people. Picture an incredibly skinny but wirey, strong, and fast Taiwanese man. Then increase the size of that man's wirey muscle and internal organs, until the person weighs 300 lbs. Yes he looks strong, but he is even stronger than he looks.

He's the strongest NFL player in history according to the NFL strength test. Even stronger than people who cheated and tested positive for steroids.

If the only Asians in America were from Tonga, Samoa and Hawaii? Then US medical textbooks would make all kinds of horrifically wrong conclusions about Asian people and health risks.
️They'd apply outlier observations to billions of people.
That's what happens to Black people. Not quite as extreme, but same principle.

@davidnjoku I found this to be a very interesting paper that basically found that Black babies born to immigrants had normal birthweight, but the next generation had lower birthweight. They posit this is due to the cumulative effects of discrimination over the lifetimes of Black mothers in the US.

Genetic characteristics of ethnicities. The significant comment here is that overall the genetic diversity of any ethnic group. It’s about the same.
As far as medical differences, though, you have to factor in socioeconomic elements, diet proximity to healthy or unhealthy environment the kinds of jobs available.
I will know that your choice of things to look at, can also be contrasted with other things that people of color are better off on and don’t suffer as much disease from
