Thanks @OldDog. There are a couple of things that caught my immediate attention, however.
First, at 5:15 Lustig displays a graphic regarding NeuroFast that clearly states …" the only currently known exception is caffeine which via specific mechanisms can potentially be addictive." Then subsequently he wonders why NeuroFast dismisses caffeine as an addictive substance commonly found in food. They obviously do not. So I wonder how he got that wrong and why. NeuroFast also states that they don’t consider alcohol a ‘food’ and thus exclude it in their findings. You could of course wonder why so, as does Lustig, since much alcohol is consumed with food and most people consider it a part of the meal. The reasons could be other than what Lustig implies: that NeuroFast is just trying to exclude the very substances that contradict their conclusions. He fails to cite any reasons for or against.
Then (around 6:30-45) he draws a non-sequiter conclusion. NeuroFast has simply stated that they find no convincing scientific evidence to support the ‘addictive food theory’. I.e. they did the study and drew a conclusion. They may be wrong or right and further studies will either confirm or disprove. Fair enough, that’s how science works. There may already be other studies that Lustig could cite contra to NeuroFast’s conclusions. But rather than cite any, Lustig immediately claims that they are thus providing cover to the food industry and blaming individuals for addictive behaviour. Why does he do that? It seems to me that he has his agenda and is selecting and interpreting data to support it. from what follows he does not need to do that.
From that point, Lustig does present a case for addictive foods and I think a good case. And it becomes clear that he considers caffeine a prime contributor. So I suppose that helps understand his initial antagonism towards the NeuoFast study. Even though it did not exclude caffeine as he claimed. Lustig finally goes after the legal definitions of GRAS and I think makes some valid points regarding ethanol, fructose primarily, but other ‘added’ sugars, and caffeine.
What I find intriguing is the importance of fructose in initiating/maintaining addiction. This because both fructose and ethanol follow very similar metabolic pathways and both can lead to addictive behaviour. I think this warrants more study. It may well be that ethanol/fructose are in a real sense a 4th macro. And a non-essential macro that potentially leads to addictive behaviours.
Thanks a gain for posting this link.
