Sugar
Sugar
Here is Dr. Lustig's full 1.5 hour lecture.
If you want an excellent 11 minute synopsis which hits all the big points, this gentleman does a great job (and he admits he used to believe that metabolism is simply math - who of us were not taught that?)
Slowly but surely the mainstream media are catching on to the latest research...at least to some degree.
I think Dr. Lustig is right, however he drives me nuts with his government regulatory solutions. It is absurd and his own lecture demonstrates why this is so. He well notes that over the last few decades without ANY significant government regulation, Americans have by and large reduced our fat intake as we were told to do. In other words, education was enough to do the job and as people sought out low fat foods, the industry responded. Sadly, our listening to the government led to increased heart disease, increased high blood pressure, increased rates of diabetes, and of course increased rates of obesity. But by golly we certainly didn't need government to regulate us into the ailments...we simply do what they tell us.
The other issue that bothered me is how he somewhat glosses over the issue of government's role in his "fructose perfect storm." There is only ONE reason why HFCS is cheaper than sugar and that's because of government regulation. If I may quote from "Wikinvest": "The primary driver of sugar prices is government regulation. Many governments heavily subsidize their sugar manufacturers, to "dump" cheaply-priced sugar in the market, while the United States government has tried to elevate prices within its borders by imposing import restrictions." And voila, HFCS is cheap in comparison.
Now, Dr. Lustig doesn't seem to think there is anything particularly MORE wrong with HFCS than sugar and I'm in no position to argue with him - though others likely are so.
Comments
I am always skeptical about people claiming that once upon a time "We" ate such and such an amount of this kind of food, then it went to this amount, etc. I certainly agree there is more obesity and diabetes and such, but my father's generation didn't exercise either unless forced to. There were fewer diabetics around for one thing because they just died instead of getting medicated, same for heart disease patients. I also agree that HFCS is nasty stuff and I eat it just about never. I bake the bread I eat, I cook just about everything I eat. HOWEVER I still am overweight because my calories in > calories out! That happens whether good ones or bad! I wish it were different. I'll listen to the long version soon!
While it is of course a general truth that counting calories is a basic foundation of weight gain (I'm thinking of perhaps comparing Newtonian and Quantum physics), there's clearly a GREAT deal of feedback loops and cofactors etc etc that play roles in what we do with calories...we are FAR more complex than a combustion engine.
If nothing else I am SURE of this much: if in fact fructose does all that he says (including inhibiting the Leptin pathway - which will lead one to seek out MORE calories no matter what the real need may be) then sugar poses some serious issues far beyond obesity - but certainly plays a role in it.
Definitely listen to the Dr. Lustig lecture.
Japanese it turns out DO eat sugary things! It doesn't undermine everything he says, some commenters simply wish he'd said more about dose of the substance. No one will OD on Fructose via *fruit*. It's unliely you'll eat six oranges, but anyone can drink too much orange juice. Which makes the phenomenon of juicers as a cure-all a bad idea.
As I mentioned I think he glosses over the role of government in keeping sugar prices artificially high and he demonizes businesses too much. Businesses do WHATEVER consumers want and they'll do it FAR faster than government. If we want less sugar, they will provide it.
