I happened to be watching a PBS show that mentioned Caldwell Esselstyn and the diet he recommends (he is a heart surgeon.) I was blown away by how much I misunderstood about a good diet. Lots of the standard "good diet" advice now looks like "fad" to me (eg. Mediterranean as a role model - since it really only shines in comparison to our horrible Western diet.) Of course, now it is even harder to eat a good diet... Perhaps his key observation is the relationship between oils and so many of our modern diseases. I do suspect that some oils have benefits which outweigh the costs (a subtlety which isn't reflected by his coarse data) For example I suspect that oils from Salmon and Walnuts may have benefits yet to be fully quantified.
