Can’t see the forest for the microbes

  Cryotube-wielding scientists are the latest in a long line of researchers studying hunter-gatherer groups throughout the world that seek balance between the prying nature of research and the rights and respect of indigenous cultures. In a timely discussion, Dominguez-Bello and others[1] foretell of a future where mining the microbial richness of native peoples is…

The Human Microbiome as Road Kill in the Age of the Anthropocene

  With the world entering a new geological epoch – the Anthropocene – the idea that we now live in a very different world than the one our not-so-distant ancestors inhabited, has never been truer. But amidst global deforestation, melting ice sheets, and general biosphere degradation, perhaps the human microbiome – the collection of our…

Paleo versus Vegetarian – who eats more fiber?

I often hear Paleo and Primal eaters say their shopping carts almost always look like that of a vegetarian grazing through the same super market when it comes to the non-grain veggies it contains. This comment – in my experience – often follows when addressing critics who say that a Paleo/Primal diet focused on fat…

Microbial Diversity: sometimes you have it, sometimes you don’t

This past January I wanted to see what would happen to my gut flora if I adopted a hunter-gatherer diet for a week – eating the plants, animals and drinking the same water as the Hadza hunter-gatherers of east Africa that I was working with. Among other hypothesis I wanted to test, would immersing myself…

(Re)Becoming Human

AS THE SUN set over Lake Eyasi in Tanzania, nearly thirty minutes had passed since I had inserted a turkey baster into my bum and injected the feces of a Hadza man – a member of one of the last remaining hunter-gatherers tribes in the world – into the nether regions of my distal colon….

Please Pass the Microbes

A few days ago I accompanied two Hadza hunters to a series of seeps or springs where they had set up hunting blinds of tall grass to ambush thirsty animals. It’s late dry season in Tanzania and dwindling water sources force otherwise dispersed animals to aggregate, and if you’re a hunter-gatherer, this is a good…
