How many calories is that human? A nutritional guide for prehistoric cannibals

Early humans ate each other — but why?

If you were to eat, say, another human being, how many calories would you be taking in? That’s a valid question not only for health-conscious people, but for anthropologists, too. You see, our human ancestors were cannibals — but we don’t really know why. Did they kill and eat each other like they would a mammoth or a wholly rhino — for the meat? Or were they practicing some sort of religious ritual? Continue reading “How many calories is that human? A nutritional guide for prehistoric cannibals”

Bodily Heatmaps Of Emotions

Bodily Heatmaps Of Emotions
Bodily topography of basic (Upper) and nonbasic (Lower) emotions associated with words. The body maps show regions whose activation increased (warm colors) or decreased (cool colors) when feeling each emotion.

Emotions are often felt in the body, and somatosensory feedback has been proposed to trigger conscious emotional experiences. The heatmaps reveal bodily sensations associated with different emotions using a unique topographical self-report method. The participants were shown two silhouettes of bodies alongside emotional words, stories, movies, or facial expressions. They were asked to color the bodily regions whose activity they felt increasing or decreasing while viewing each stimulus. Different emotions were consistently associated with statistically separable bodily sensation maps across experiments. These maps were concordant across West European and East Asian samples.

Eating Right Can Save the World

how do you figure out the most sustainable diet?

Most of us are aware that our food choices have environmental consequences. (Who hasn’t heard about the methane back draft from cows?) But when it comes to the specifics of why our decisions matter, we’re at a loss, bombarded with confusing choices in the grocery-store aisles about what to buy if we care about planetary health. Are organic fruits and vegetables really worth the higher prices, and are they better for the environment? If I’m a meat eater, should I opt for free-range, grass-fed beef? Is it OK to buy a pineapple flown in from Costa Rica, or should I eat only locally grown apples?

But the simple goal of a healthy, sustainable diet seem hopelessly complex.
