Disease and the transition to a modern diet

Good post by Stephan Guyenet from Whole Health Source, Dr. Kevin Patterson on Western Diets and Health, about a Canadian physician Kevin Patterson who writes about the diseases of civilization and the transition from a traditional diet among native peoples of Canada to a more "modern" one -- full of processed foods and cheap calories.
He discusses the "epidemiological transition", the idea that cultures experience predictable changes in their health as they go from hunter-gatherer, to agricultural, to industrial. I think he has an uncommonly good perspective on the effects of industrialization on human health, which tends to be true of people who have witnessed the effects of the industrial diet and lifestyle on diverse cultures.
Jump over for more.  Reading through that brought be to an article written by Kevin Patterson Diseases of Affluence. In it he discusses his experience as a doctor in Afghanistan, and the lives of traditional Polynesian and arctic peoples.
Around the world, as traditional peoples and societies have been absorbed into the global monoculture, the prevalence of diabetes has exploded. Since 2001, premature death from obesity has exceeded death from malnutrition. The milestone was reached at almost the same time as another: for the first time in history, the number of urbanites exceeds the number of rural dwellers. Canada is an example. For all its magnificent and extensive wilderness, 87 percent of the population lives in a community with at least ten thousand neighbours. Afghans are at the other end: less than 12 percent live in cities. No lattes, no internet, no phone, no pool. And no XXXL elastic stretch pants. After wealth and death rates, the biggest difference between Afghanistan and Canada—and the hallmark of the world’s creeping homogeneity—is urbanization.
An excellent discussion of the key issues facing all of us who have already made the transition, and what we consider "normal" parts of daily life and aging.

New article by Dr. Kurt

Dr. Kurt Harris is now writing for Psychology Today.

Good start with an important article "Cardio" may cause heart disease.
I first saw this study by Brueckmann and Mohlenkamp in the spring of 2009 and I'm a bit surprised that the nutrition and fitness blogosphere hasn't really noticed it. I think you may have to be an academically-oriented cardiologist or radiologist to really understand the significance of the findings, as the MRI imaging science is a bit esoteric.
Also, it's published in Radiology, which is not exactly Gina Kolata territory.
I'll do my best to convince you of just how disturbing this study should be to those who believe that "aerobic" exercise will make you immortal....
The more marathons run, the higher the likelihood of heart disease. The number of marathons run was an independent and significant predictor of the likelihood of myocardial damage.
Jump over to the article for more.  He includes an excellent discussion of medical imaging/tests, limits of the research, implications of this (and other) studies, etc.  All in a very readable style, and good food for thought.

Dr. Gary Taubes on Insulin

Great post by Dr. Gary Taubes on insulin, health and obesity.

Insulin puts fat in fat cells. That’s what it does. And our insulin levels, for the most part, are determined by the carb-content of our diet — the quantity and quality of the carbohydrates consumed. (Or if Jenny Brand Miller and her colleagues are right, also by our fat content — the lower the fat in the diet, the higher the insulin and vice verse.) The way to get fat out of fat cells and burn it, which is what we want to do with it, is to lower insulin. This has been known since the early 1960s.
One point I make in Why We Get Fat is that we all respond to this carbohydrate/insulin effect differently. Some of us can eat carbohydrate-rich meals and burn them off effortlessly. We’re the ones (like Oz) who partition the carbs we consume into energy. (This is the fuel gauge metaphor that I use in WWGF and that Oz’s producers reproduced wonderfully on the show.) And some of us partition the carbs we consume into fat for storage, and that partitioning depends on a lot of different enzymatic and hormonal factors — mostly relating to insulin and LPL as Williams Textbook of Endocrinology said)....
... A blanket recommendation to eat fruits and vegetables and whole grains, as Oz prescribes and now Weight Watchers and the U.S. Dietary Guidelines, ignores this aspect of human variability completely. It assumes that people who are predisposed to fatten can tolerate the same foods and benefit from the same very mild dose of carb-restriction that the naturally lean can.
I don’t think that’s true. It’s that simple. I think that if we’re so predisposed to fatten that we’re already obese, we’re probably among those who have to restrict carbs far more severely – have a much greater dose of the intervention – to get even relatively lean, which means relatively healthy. So for some of us and maybe most of us, even fruit, the nutritionist’s darling of the early 21st century, can be fattening , and if it’s fattening, it means it’s probably causing far more problems than whatever antioxidants or phtyochemicals it contains may be preventing.
Jump over to The Dose of Intervention and the Land of Dr. Oz for more.  The writing on his blog is brilliant, especially about overeating and being sedentary.

Carbs and cocaine

Good article in Details magazine.  If you're concerned about your health, it is a must read.

ARE CARBS MORE ADDICTIVE THAN COCAINE?

...[F]ast-burning carbohydrates—just like cocaine—give you a rush. As with blow, this rush can lead to cravings in your brain and intrusive thoughts when you go too long without a fix. But unlike cocaine, this stuff does more than rewire your neurological system. It will short-circuit your body. Your metabolism normally stockpiles energy so you can use it as fuel later. A diet flush with carbohydrates will reprogram your metabolism, locking your food away as unburnable fat. When you get hungry again you won't crave anything but more of the same food that started you down the path to dependency. Think of this stuff as more than a drug—it's like a metabolic parasite, taking over your body and feeding itself.
