American Milk Intolerance Caused By Specific Cow Protein?

You’re Drinking the Wrong Kind of Milk | Mother Jones

When my in-laws moved from India to the United States some 35 years ago, they couldn’t believe the low cost and abundance of our milk—until they developed digestive problems. They’ll now tell you the same thing I’ve heard a lot of immigrants say: American milk will make you sick.

It turns out that they could be onto something. An emerging body of research suggests that many of the 1 in 4 Americans who exhibit symptoms of lactose intolerance could instead be unable to digest A1, a protein most often found in milk from the high-producing Holstein cows favored by American and some European industrial dairies. The A1 protein is much less prevalent in milk from Jersey, Guernsey, and most Asian and African cow breeds, where, instead, the A2 protein predominates.

“We’ve got a huge amount of observational evidence that a lot of people can digest the A2 but not the A1,” says Keith Woodford, a professor of farm management and agribusiness at New Zealand’s Lincoln University who wrote the 2007 book Devil in the Milk: Illness, Health, and the Politics of A1 and A2 Milk. “More than 100 studies suggest links between the A1 protein and a whole range of health conditions”—everything from heart disease to diabetes to autism, Woodford says, though the evidence is far from conclusive.

I don’t drink milk – because I can’t tolerate it.

About Bill Quick

I am a small-l libertarian. My primary concern is to increase individual liberty as much as possible in the face of statist efforts to restrict it from both the right and the left. If I had to sum up my beliefs as concisely as possible, I would say, "Stay out of my wallet and my bedroom," "your liberty stops at my nose," and "don't tread on me." I will believe that things are taking a turn for the better in America when married gays are able to, and do, maintain large arsenals of automatic weapons, and tax collectors are, and do, not.

  1. I remember growing up – when milk was delivered to the doorstep – the local farms all advertised it as being from Guernsey cows. And I don’t remember hearing the words lactose intolerent anywhere.

    What’s with the new weird sign-in match game, Bill; trying something different?

  2. I think this comment belongs on a different thread but I did think the juxtaposition of a comment speaking of “generalized misery” on a thread about lactose intolerance oddly hilarious.

    Maybe it’s just me though.
