The Deeper Roots of Health and Diet – Ron Rosedale (AHS12)

Dr. Rosedale’s presentation at Ancestral Health Symposium 2012 (AHS12) is not great. But it is damn good. In his talk, he takes the long view on a lot of nutrition topics. In this context, you might expect “the long view” to mean 10 million years or so… but no, he takes the long looong loooooooooong view. As in, ~4 billion years long. He starts from the earliest forms of life on Earth and walks us up to the present, touching on various implications for nutrition along the way.

60 Minutes Rebroadcasts the “Is Sugar Toxic” Segment Tonight

A new CBS 60 Minutes Segment with Sanjay Gupta again looks at the role of sugar in many illnesses from from cancer to diabetes to obesity.

New recommendations for _maximum_ sugar consumption is 150 calories sugar a day for men, and 100 calories sugar a day for women. That works out to about 37 grams of sugar a day for men, and 25 grams of sugar a day for women. For reference, Again, that’s the _maximum_ recommended intake by Dr. Robert Lustig. For Reference, a single 12-oz can of Coke Classic contains 39 grams of sugar, more than the recommended DAILY intake of sugar for either gender. Dr. Sanjay Gupta makes special note that, “Every researcher we talk to is completely eliminating sugar from their diet.”

Dr. Robert Lustig – The Skinny on Obesity – Episode 4

In this the fourth episode of the series, Dr. Lustig looks at sugar’s effects on brain chemistry, specifically, how our reward system (mediated by dopamine in the nucleus accumbens) is changed in response to chronic overconsumption of sugar.

Specifically, Lustig asserts that sugar downregulates the same dopamine system in the nucleus accumbens (reward center of the brain) that drugs like cocaine do. In this sense, an addiction marked by domamine resistence in the pleasure center is an additional driver of obesity in addition to the leptin and insulin resistence he described in previous videos. All, of course, are the result of sugar consumption

Dr. Donald W. Miller – Enjoy Eating Saturated Fats: They’re Good For You

Dr. Miller, professor of cardiothoracic surgery at the University of Washington, gives a nifty talk in which he frames the historical context for our mistaken fear of saturated fats and tries to expose the real science that should inform our consumption decisions.

Really a worthwhile video to watch if you’re concerned about “all the fat” you’re eating on a low carb ketogenic diet.

Dr. Robert Lustig – The Skinny on Obesity – Episode 3

In the third installment of Dr. Robert Lustig’s, The Skinny On Obesity series, Dr. Lustig covers how our consumption of carbohydrate rich diets influence the roles of insulin and leptin hormones in our bodies, and how these contribute to obesity.

This directly addresses the misleading (and dangerous) notion that “a calorie is a calorie.” It turns (and this is no surprise to anyone who pays attention to nutrition research, really) out that different types of calories trigger different responses in the body’s hormonal response.

Dr. Eric Westman – Duke University New Atkins Ketogenic Diet for Weight Loss

Looks like Dr. Westman put together a video covering his intro at his clinic.  It’s a great resource if you are contemplating a low carb/ketogenic diet, or you have someone in your life who wants to know more about it, is suspicious about it and thinks its a crackpot, non-scientific approach. Dr. Westman is a respected physician working at a respected medical university.

Funny how people have an easier time believing the crackpot on TV than someone like this.
