Even more about ancient beer

Further to my recent post about ancient beer in Israel and elsewhere, here's a pretty fascinating story about how it seems beer drinking Nubians were getting hefty doses of antibiotic from their beer:

Armelagos was part of a group of anthropologists that excavated the mummies in 1963. His original goal was to study osteoporosis in the Nubians, who lived between about 350 and 550 A.D. But while looking through a microscope at samples of the ancient bone under ultraviolet light, he saw what looked like tetracycline — an antibiotic that was not officially patented in modern times until 1950.

At first, he assumed that some kind of contamination had occurred.

"Imagine if you're unwrapping a mummy, and all of a sudden, you see a pair of sunglasses on it," says Armelagos. "Initially, we thought it was a product of modern technology."

His team's first report about the finding, bolstered by even more evidence and published in Science in 1980, was met with lots of scepticism. For the new study, he got help dissolving bone samples and extracting tetracycline from them, clearly showing that the antibiotic was deposited into and embedded within the bone, not a result of contamination from the environment.

The analyses also showed that ancient Nubians were consuming large doses of tetracycline — more than is commonly prescribed today as a daily dose for controlling infections from bad acne. The team, including chemist Mark Nelson of Paratek Pharmaceuticals, reported their results in the American Journal of Physical Anthropology.

The theory is that it was from grain used for beer making that was contaminated with tetracycline producing mold.

In my previous post it was mentioned how some anthropologists believed beer drinking was very important in the development of human society. Well, if beer gave other tribes healthy doses of antibiotics, it probably can't hurt that theory.
