Yes, yes, you can tell me all about why I definitely shouldn’t be eating those mashed potatoes in a moment. But right now, I’ve got some news for you (and some potatoes to eat).
A new study in September’s Quarterly Review of Biology attempts to do some forensic reconstruction of ancient human diets using an interesting method: looking at physiological changes and the nutrition that would have been necessary to support them. Of particular interest to the researchers were a pair of salivary amylase genes that began to rise a million years or so ago, along with the rise of cooking.
What always bugged me about ‘paleo’… ancient humans ate whatever was handy. If grains and tubers were nearby, that’s what people ate. The diet of someone in the tundra is vastly different from someone in Polynesia, whose diet was different from someone in the rain forest.
