Thanks Wendy, it's really useful to have Swank's Lancet paper - I hadn't been able to find it before (a testament to my poor search skills I'm sure). Swank rules out coconut oil because of the "preponderence of saturated fatty acids"
and, on re-reading 'the book' I see that George's reasoning is the same ("the concentration of saturated fats is simply too high"
Susan, thanks for the article. The reason I was interested is because there is some research evidence that coconut oil can prevent Alzheimers (http://www.greenmedinfo.com/blog/sugar-and-your-brain-alzheimer%E2%80%99s-disease-actually-type-3-diabetes
). I'm not a scientist, so don't know where this sits on the the 'hierarchy of evidence', but hopefully significantly higher than cat pee (to carry on George's analogy)...
I think it's right to kick the tyres on all aspects of the diet and lifestyle, and, having done so, in light of the amount of sat fat in coconut oil and Swank's and George's opinions, I'm in full agreement that coconut oil should be avoided as part of the OMS diet.
