Thanks for your comments, Pete. I don't think the good doctor needs my help defending him or his message. I was just intrigued by the personal attack when I had not seen it before in many other posts. So I asked why, and the answer really was I believe in a low fat diet. My personal position is if you don't agree with the message, attack the message, not the messenger. Don't try to get people to not watch the clip, or undermine the information ahead of time based on undercutting the competency of the presenter. I have followed this guy for decades, and he knows exactly what he is talking about regardless of the quality of the presentation.
But that misses the point this thread brings up. What most of you don't know is that this guy was one of the national leaders in hoisting the low fat diet on the general public. Now that he is not leading a large well respected (rightfully) institution intent on getting government money for its research and has a safe, tenured job as a medical professor, he is speaking what he thinks.
This little clip reflects someone who was 'in power' and leading the charge, saying he was wrong and totally changing his position on a topic. Maybe he is as wrong now as he was before, but personally I think he got it right this time. Sometimes wisdom does come with age (and new or better research).
So for those of you brought up in the low fat era, realize one of your teachers (at least in the US) has recanted his opinion.
Now whether we can really get to a 70% cal. from fat level in our diets is another matter. The snack food industry will have to come up with more high fat snacks! But you have to understand, in the US, even the Med diet's 35% cal. from fat level had the government saying 'don't' because that level of fat in a diet is lethal. And when whole populations did not fall over dead, some people actually started trying to find out why. The rest, as they say, is history.
