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….

Slumdog Microbiome More Diverse

I was recently invited to put together a series of slides – or webinar – for a national supermarket chain on things their customers could do to improve the health of their gut microbiome. Once I got past the obvious first few slides that recommend they might spend a little less time in national supermarket…

Can parasites prevent autoimmune diabetes?

A guest post by Moises Velasquez-Manoff.   Coronado Biosciences, a company seeking FDA approval for a type of medicalized parasite, recently announced the beginning of a very interesting trial on Type 1 diabetes. Coronado is running a number of studies with a whipworm called Trichuris suis, which is native to pigs. It’s testing the parasite…

Are you carrying the obesity pathogen?

I can remember where I was and what I was doing when it happened. I was sitting in my usual spot at Sound Café in the Marigny neighborhood of New Orleans sipping coffee on a Sunday morning. It was mid-August, 2006. It wasn’t a tragic event that locked this place and time in my memory,…

An eaters guide to a healthy microbiome

“I have 15 cows, how many do you have?” Chief Jambiru asked me. “How many cows do I have?” I thought. What an odd question. But I shouldn’t have that so, as I had just asked the Chief how many cows he owned. Turning my bovine query back on me caught me a little off…

Are you there Al Gore? It’s me, Microbiome

In the 50 years since the book “Silent Spring” sounded the alarm on humankind’s poisoning of the biosphere with synthetic pesticides like DDT, the grass roots environmental movement has tackled issues ranging from clean air and water, animal rights and acid rain to the more recent mega issue of global warming. Despite these and many…

Nutrition’s ‘dark matter’

AS ANY reader of this blog knows, the human body is a mash up of human and microbial cells – with the microbial cells outnumbering our own 10 to 1. When you also consider the fact the human genome (our first genome) contains only 22,000 genes, but that our gut microbiome (our second genome made…

A Window Into Your Health

Sitting on the floor of a traditional Himba hut in northern Namibia this past summer, I found myself staring at a peculiar hand-sized hole located about halfway up the curved wall thinking to myself, “what could be the purpose of such a small opening?” Turns out, it was the sole portal to the outside world…

Ghosts of our African Gut

Every person on earth has two genomes. The genome we inherit from mom and dad is the one we are most familiar, and more or less stuck with for life. Our second genome, the one we initially acquire from mom as we pass through the birth canal, is more dynamic and made up of the…

Guts, Germs and Meals: what 37 microbiologist say about diet

Earlier this year (in 2012), U.S. News & World Report  reported its second annual list of the Best Diets, as ranked by a panel of  “22 nationally recognized experts in diet, nutrition, obesity, food psychology, diabetes, and heart disease.” The expert panel evaluated 28 diets including the well known Atkins, South Beach Diet, Biggest Loser…

From turtles to tortillas: the evolution of our low GI diet

PACKED INTO four-wheel drive vehicles, ten middle-aged men and women traveled nearly two days on bumpy dirt roads and trails to reach a remote location, deep in the middle of nowhere. For seven weeks they would live off the land as hunter-gatherers, completely cut off from the niceties’ of the modern world they were born…

Desert Drifting with Cody “Barefoot” Lundin

  ACCORDING to the World Health Organization, key causes of hunger are natural disasters, conflict, poverty, poor agricultural infrastructure and over-exploitation of the environment. I would add to that list spending a week in the high desert of Arizona with Discovery Channel’s Dual Survivor star Cody “Barefoot” Lundin. Billed as no ordinary weeklong survival course,…

Do spider monkeys hold the key to why we get fat?

IN EARLY 2004, a team of researchers spent nearly five months in a lowland subtropical forest in Bolivia following spider monkeys – an arboreal primate that primarily dines on ripe fruit and leaves. From dawn to dusk, the researchers recorded every detail of the dietary habits of these wild spider monkeys. They monitored the length…
