One of the worst epidemics in human history, a sixteenth-century pestilence that devastated Mexico’s native population, may have been caused by a deadly form of salmonella from Europe, a pair of studies suggest.
In one study, researchers say they have recovered DNA of the stomach bacterium from burials in Mexico linked to a 1540s epidemic that killed up to 80% of the country’s native inhabitants. [continue]
Up in the arctic, life struggles to thrive. A rocky and frigid landscape supporting little more than meager shrubs, grasses, and some berries in the summer, it’s proven too hostile for more than a few animal species that have specially evolved to polar environs. Yet despite the harsh conditions, thousands of years ago human beings managed to etch out a life for themselves in the snows. These peoples’ ability to live in these regions is mostly due to a diet that to most of us seems narrow and anemic, but in truth has proven itself one of the most robust and healthy in the world.
Arctic diets vary vastly from region to region, according to the local environment’s flora and fauna. But at their most extreme, they consist of almost nothing but meat and fish, often from animals rich in fat (think polar bears, seabirds, and whales). For those of us who grew up learning the American Food Pyramid, or even the unholy devilcraft that is the new “My Plate” system, such a meat-heavy diet sounds borderline suicidal. But when eaten raw, these animals’ organs provide ample nutrients, including the vitamins we temperate-zoners draw mostly from plants. Blubber is also surprisingly rich in heart-healthy monounsaturated and polyunsaturated omega-3 fats and natural fermentation provides arctic diets with the benefits of probiotic foods. The result is a food regimen that provides everything a human needs, as well as one of the greatest natural defenses against diabetes, heart disease, certain types of cancer, and perhaps even seasonal effective disorder, illustrating that in any diet, there are no essential food groups, just essential nutrients.

How fascinating is that? I love reading about traditional diets, and have, over the years, changed my own diet quite a bit in order to cut out all processed food. These days I try to eat the sort of foods that humans ate before industrialization and nutritional stupidity. Are any of you doing that, too?
I ate reindeer meat in Norway, though I haven’t tried reindeer blood. Perhaps on another visit I will see if there are any Sami communities that welcome visitors like me.
