Genetic research and livestock origins

From The Pig Site.com

“GLOBAL – Modern cattle are descended from a small herd domesticated in the Middle East about 10,500 years ago, according to recent genetics research.

Researchers extracted DNA from domestic cattle bones found at archeological sites. By examining the DNA of ancient and modern cattle, they traced taurine cattle to about 80 female aurochs. Taurine cattle include beef breeds like Herefords and Angus, and dairy breeds like Holsteins.

The study, published in the Journal of Molecular Biology and Evolution, states that the low number of domesticated aurochs indicates “initial domestication took place in a restricted area and suggests the process was constrained by the difficulty of sustained managing and breeding of the wild progenitors of domestic cattle.”  Continue reading

Of dairy queens and human cheese

From Puff the Mutant Dragon blog:

Calvin and Hobbes comic strip via Puff the Mutant Dragon blog.

“A couple of years ago, an enterprising New York chef made headlines by serving cheese made from his wife’s breast milk. His stunt provoked a swift reaction from the New York Health Department, which didn’t seem to find this novelty menu item amusing. Despite his venture’s unsuccessful end, a London ice cream parlor tried to imitate him last year by selling a breast-milk-based product.

Do you find the idea of human cheese and ice cream bizarre? Disturbing? If so, it’s not very difficult to see why. What’s more difficult to explain is how we came to drink milk from other mammals in the first place. Continue reading

Mounting opposition to GMOs as the world’s people reject genetic pollution of food and the environment

Here’s the scoop from Rady Ananda, excerpted from Global Research.ca:

GMO grapevines destroyed -- Frence citizens destroy trial vineyard. Agence France Presse photo.

“Early Sunday morning, French police stood help less as sixty people, locked inside an open-air field of genetically modified grapevines, uprooted all the plants. In Spain last month, dozens of people destroyed two GMO fields. On the millennial cusp, Indian farmers burned Bt cotton in their Cremate Monsanto campaign. Ignored by multinational corporations and corrupt public policy makers, citizens act to protect the food supply and the planet. Continue reading

Beta-casein A1 and A2 in milk & health

Could milk from Guernsey cattle be more healthy than milk from Holsteins due to genetic factors? — little known research from down under focuses on Beta-casein A1 and A2 in milk and human health.

“There are several genetically-determined variants of B-casein, the protein which constitutes about 25-30% of cows’ milk proteins. One variant, A1 B-casein, has been implicated as a potential etiological factor in type 1 diabetes mellitus (DM-1), ischaemic heart disease (IHD), schizophrenia and autism. Another variant (A2 B-casein) has not been implicated in these diseases….”

The excerpt above is from a 2004 report to the New Zealand Food Safety authority by Professor Boyd Swinton, professor of public health nutrition, Deakin University, Melbourne. Read the whole 43-page report here.

While this story is not about raw milk specifically, it is about interesting research on an aspect of milk with major health implications, research that seems to have been largely buried or ignored.

Apparently, the predominance of A1 or A2 B-casein is related to the breed of cattle which the milk comes from. For instance, Holsteins seem to have mostly A1, while Guernseys have predominantly A2. Here’s a further discussion of the issue from Gordon Watson’s “Bovinity”. The excerpt below is from a story by Tom Valentine titled “A1 A2 milk gene story too important to ignore“. It looks like the story was originally from “True Health“, although searching now on the http://www.truehealth.com website for “A1 A2” or even “milk” yields no results. Curious.

“… It’s all about one ittybitty gene, and it’s driving me nuts

I know I should not let things get me so upset. After all, it isn’t as though there aren’t a myriad other irrational, illogical corrupt and asinine public positions taken in the health and food sector – so why should this one get to me more than the others? Continue reading
