Mark, thoughts on the new study “Hunter-gatherers as models in public health.”
Very interesting. I’ll discuss it briefly today, and maybe later on go into it more in depth.
It hits most of the points I’ve been discussing for years.
Daily activity level is high (over 100 minutes per day of moderate to vigorous activity), energy expenditure is no higher than modern people. So they’re moving around a lot at a slow/moderate pace, but they aren’t chasing “calorie burn.” It’s the daily, frequent movement you do that matters most, not the number of calories you burn in order to “earn” that trove of mongongo nuts or slab of honeycomb.
Calorie density low, micronutrient density high. This is the opposite of the modern Western diet, which is high in calories and low in micronutrients.
Carbohydrate content varies, but is always accompanied by high fiber intake. These guys are eating over 100 grams of fiber, much of it prebiotic substrate for their gut bacteria, a day on the regular.
Normal lifespan (60-70+ years), assuming they survive childhood and young adulthood. They’re not “dropping dead at 30” en masse. Most deaths caused by infection or trauma—two things modern medicine is great at treating.
There’s much more, but that’s a good overview for now.
