Is the Dairy Industry (Inadvertently) Poisoning Black Children?

 I could never understand the National Dairy Council's ads targeting young blacks, when medical research has shown that at least eighty percent of African-Americans, are by age twelve, lactose-intolerant.  Of course, supermarkets now market lactose-free milk.  But hold on a second. . .   Lactose-intolerance is not a disease and should not be treated as one.  It is rather a human trait blacks share with  95% of the world's population.  People of Northern European ancestry and a few isolated enclaves elsewhere, have a high tolerance for lactose because a large proportion of their ancestors' food supply came from dairy farming.  West Africans on the other hand, had little exposure to dairy products because of the  susceptibility of cows to the ubiquitous tsetse fly.

Milk is America's "sacred cow."   But why should blacks, Asians too, for that matter, be targeted in dairy industry campaigns promoting the health benefits of a beverage that sends most non-Europeans groping for the bathroom door knob? 

Unfortunately, little if any research attention has been given to understanding the biological mechanisms at work on healthy adult populations, who do not traditionally drink milk.  For instance, West Africans from whom black Americans are descended, suffer  a whole host of medical problems.  But bad teeth, osteoporosis and other symptoms of calcium deficiency are not among them.  This is so even though their consumption of milk ends at age three, when the mother stops breastfeeding..


The National Dairy Council is not to blame for an insidious form of  racial blindness,which applies the nutritional needs of Northern Europeans to Africans and Asians.  The underlying assumption is that the biochemistry of whites represents a universal standard, and any deviation from it, must be pathologized.    Many of us African-American parents are wringing our hands with distress at the explosive epidemic of childhood obesity in our community.  But too few of us are asking questions and demanding to know whether the nutritional advice being fed to our children is contributing to rather than fixing our health problems.

Why I'm (Almost) Feeling Sorry for the Ku Klux Klan

America has for far too long dumped the burden of racism on the shoulders of a motley bunch of  illiterate, rednecks.  It's true that at the turn of the last century the Ku Klux Klan terrorized, lynched and invariably castrated innocent black men.  Southern politicians even packaged their brand of hate to keep themselves in office.  But America is today confronted with a deeper truth about racial bigotry that our nation seems unable or just unwilling to face, despite having a black man in the White House.

¿El gobierno de Obama rompió relaciones con los agricultores hispanos y las mujeres agricultoras?

Has Obama Burned Bridges with Crucial Demographic?

Sometime in the early 1980s, the United States Department of Agriculture (USDA) dismantled its civil rights enforcement arm – in secret.  For years, USDA employees dumped the discrimination-complaints of Hispanic, black, Native American and female farmers into an empty office at the USDA building in Washington, D.C. Not surprisingly, minorities who had  lost family farms to agribusiness, and to the denial of access to federal loans, celebrated the elections of 2008 as a turning point.   Presidential candidate Barack Obama had indeed promised to put things right.  But, four years later, the Obama Administration has Hispanic and women farmers still waiting for justice. These failing family farms are being bought out of bankruptcy court by agribusiness intent on introducing genetically modified crops, growth-promoting hormones in cattle and chemical pesticides, some of which are now being linked to childhood leukemia, Parkinson’s Disease and non-Hodgkin’s lymphoma.

Can Cystic Fibrosis, Tay-Sachs, Sickle-Cell Anemia be Prevented?

The medical establishment's response to inherited autosomal recessive disorders like sickle-cell anemia, tay-sachs, cystic fibrosis is, understandably, one of finding ways to relieve the suffering of the victims, or to possibly prevent them from being born in the first place.  Thus, the genetic testing of embryos, and fetuses is the preferred treatment.  However, these kinds of disorders are not at their core medical so much as they are a function of longstanding societal taboos.

Social Taboos Thwart Cures for Cystic Fibrosis, Tay-Sachs, Sickle-Cell Anemia and other Genetic Disorders

One of the most heartbreaking perils of parenthood is the discovery that one's newborn carries such genetic markers for premature death as Cystic Fibrosis, Sickle Cell Anemia, or Tay-Sachs Disease.  Life will always have risks. But the aforementioned disorders caused by the inheritance of matching recessive genes from both parents, may not have to be one of them, at least for future generations if not for present-day sufferers.  The reason is a concept called "genetic distance," which corresponds to some degree with the geographical distance between  diverse populations.  In short, the term refers to the familial closeness or distance of any two people, with the greater genetic distance signifying that the two will share fewer of the same disorder-triggering recessive genes.

Medical knowledge of recessive genes, the disorders caused by them, and the risks of inbreeding have been known for decades.    But what hasn't existed until now is the social freedom to choose one's spouse outside a narrow community of potential partners.   Given the rich tapestry of American society, drawing immigrants from all over the world, the twenty first century offers the potential for physical health and mental vigor beyond anything our society has yet known.  But we must first be willing to step outside our genetic  neighborhood.  Where the Nazis missed the boat was in believing that their ideology of racial inbreeding would lead to superior human beings.  Fortunately for their descendants, the Aryan experiment was brought to an abrupt halt with their World War II defeat. 

  In recent years, medical practitioners have increasingly used genetic tests to ferret out matched pairs of recessive genes in an embryo or fetus for the benefit of couples fearing that their children will inherit a recessive gene disorder.   But ruling out specific diseases is no guarantee that a couple will have a vigorously healthy child.  Those positive odds only rise, and they do so exponentially, when two people come together from populations that are geographically and genetically distant from one another.  In the meantime, researchers will continue to spend billions of dollars seeking better treatments for those suffering from genetic diseases, knowing that medical science is not even close to eradicating these disorders.  But carrying around a good map of the world when deciding on a date just might.
