Why are Americans so short?

I am between 5' 7'' and 5' 8'', which depending on the study puts me 2-3 inches shorter than even the American average.  But Americans as a whole are now about the shortest people in the industrialized world.  NPR had an interesting piece on this (h/t John Messie):
Through most of American history, we’ve been the tallest population on the planet. Americans were two inches taller than the Englishmen they fought in the Revolutionary War, thanks to abundant food and a healthy rural life, far from the disease-ridden cities of Europe.

But we’re no longer at the top. Northern Europeans are now the world’s tallest people, led by the Dutch. The average Dutch man is 6 feet tall, while the average American man maxes out at 5-foot-9.

Good health care and good nutrition during pregnancy and early childhood are two reasons why the Dutch have grown so tall, Komlos says. In addition, the Dutch guarantee equal access to critical resources like prenatal care. That’s not the case in the United States, where 17 percent of the population has no health insurance.
  An excellent New Yorker article from several years by Burkhard Bilger ago laid it out in great detail:
Then something strange happened. While heights in Europe continued to climb, Komlos said, “the U.S. just went flat.” In the First World War, the average American soldier was still two inches taller than the average German. But sometime around 1955 the situation began to reverse. The Germans and other Europeans went on to grow an extra two centimetres a decade, and some Asian populations several times more, yet Americans haven’t grown taller in fifty years. By now, even the Japanese—once the shortest industrialized people on earth—have nearly caught up with us, and Northern Europeans are three inches taller and rising.

The average American man is only five feet nine and a half—less than an inch taller than the average soldier during the Revolutionary War. Women, meanwhile, seem to be getting smaller. According to the National Center for Health Statistics—which conducts periodic surveys of as many as thirty-five thousand Americans—women born in the late nineteen-fifties and early nineteen-sixties average just under five feet five. Those born a decade later are a third of an inch shorter.

Just in case I still thought this a trivial trend, Komlos put a final bar graph in front of me. It was entitled “Life Expectancy 2000.” Compared with people in thirty-six other industrialized countries, it showed, Americans rank twenty-eighth in average longevity—just above the Irish and the Cypriots (the Japanese top the rankings). “Ask yourself this,” Komlos said, peering at me above his reading glasses. “What is the difference between Western Europe and the U.S. that would work in this direction? It’s not income, since Americans, at least on paper, have been wealthier for more than a century. So what is it?”

The obvious answer would seem to be immigration. The more Mexicans and Chinese there are in the United States, the shorter the American population becomes. But the height statistics that Komlos cites include only native-born Americans who speak English at home, and he is careful to screen out people of Asian and Hispanic descent. In any case, according to Richard Steckel, who has also analyzed American heights, the United States takes in too few immigrants to account for the disparity with Northern Europe.
Bilger comes to the provisional conclusion that it's widening income inequality and our lousy healthcare system that's holding us back:
Inequality may be at the root of America’s height problem, but it’s too soon to be certain. If the poor are pulling all of us down with them, some economists say, why didn’t Americans shoot up after the war on poverty, in the nineteen-sixties? Komlos isn’t sure. But recently he has scoured his data for people who’ve bucked the national trend. He has subdivided the country’s heights by race, sex, income, and education. He has looked at whites alone, at blacks alone, at people with advanced degrees and those in the highest income bracket. Somewhere in the United States, he thinks, there must be a group that’s both so privileged and so socially insulated that it’s growing taller. He has yet to find one.
Emphasis mine. Surely there must be a sizable subgroup of people in the USA that are not in any way malnourished and able to afford the best healthcare. I am reminded of an article some time ago that I can't seem to find that proposed that height might have a social factor—that people's height is transmitted across populations to some degree.  I can't find any research on that at the moment, but it would explain how Komlos was unable to find any group growing in the US.  Thoughts?

Why Did Reality Winner Leak to the Intercept?

So Reality Winner, former NSA contractor, is in federal prison for leaking classified information — for five years and three months, the longest sentence of any whistleblower in history. She gave documents on how Russia had attempted to hack vendors of election machinery and software to The Intercept , which completely bungled basic security procedures (according to a recent New York Times piece from Ben Smith, the main fault lay with Matthew Cole and Richard Esposito ), leading to her capture within hours. Winner recently contracted COVID-19 in prison, and is reportedly suffering some lingering aftereffects. Glenn Greenwald has been furiously denying that he had anything at all to do with the Winner clusterfuck, and I recently got in an argument with him about it on Twitter. I read a New York story about Winner, which clearly implies that she was listening to the Intercepted podcast of March 22, 2017 , where Greenwald and Jeremy Scahill expressed skepticism about Russia actually b

The Basic Instinct of Socialism

This year I finally decided to stop beating around the bush and start calling myself a democratic socialist. I think the reason for the long hesitation is the very long record of horrifying atrocities carried out by self-described socialist countries. Of course, there is no social system that doesn't have a long, bloody rap sheet, capitalism very much included . But I've never described myself as a capitalist either, and the whole point of socialism is that it's supposed to be better than that. So of course I cannot be a tankie — Stalin and Mao were evil, terrible butchers, some of the worst people who ever lived. There are two basic lessons to be learned from the failures of Soviet and Chinese Communism, I think. One is that Marxism-Leninism is not a just or workable system. One cannot simply skip over capitalist development, and any socialist project must be democratic and preserve basic liberal freedoms. The second, perhaps more profound lesson, is that there is no s

Varanus albigularis albigularis

That is the Latin name for the white-throated monitor lizard , a large reptile native to southern Africa that can grow up to two meters long (see pictures of one at the Oakland Zoo here ). In Setswana, it's called a "gopane." I saw one of these in my village yesterday on the way back from my run. Some kids from school found it in the riverbed and tortured it to death, stabbing out its eyes, cutting off its tail, and gutting it which finally killed it. It seemed to be a female as there were a bunch of round white things I can only imagine were eggs amongst the guts. I only arrived after it was already dead, but they described what had happened with much hilarity and re-enactment. When I asked why they killed it, they said it was because it would eat their chickens and eggs, which is probably true, and because it sucks blood from people, which is completely ridiculous. It might bite a person, but not unless threatened. It seems roughly the same as killing wolves that
