How Western Diets Are Making The World Sick

In an essay published last November in Canada's Maisonneuve journal, physician Kevin Patterson described his experiences working as an internist-intensivist at the Canadian Combat Surgical Hospital in Kandahar, Afghanistan.

One detail he noticed: The Afghan soldiers, police and civilians he treated in Kandahar had radically different bodies from those of the Canadians he took care of back home.

"Typical Afghan civilians and soldiers would have been 140 pounds or so as adults. And when we operated on them, what we were aware of was the absence of any fat or any adipose tissue underneath the skin," Patterson says. "Of course, when we operated on Canadians or Americans or Europeans, what was normal was to have most of the organs encased in fat. It had a visceral potency to it when you could see it directly there."

"Type 2 diabetes historically didn't exist, only 70 or 80 years ago," says Patterson. "And what's driven it, of course, is this rise in obesity, especially the accumulation of abdominal fat."
