For (much) more background on the LMHR question, please also visit Dave Feldman's blog. If you don't know his work, and you're interested in lipids (whether yours or other peoples') I promise your mind will be blown by the Inversion Pattern amongst other matters.
Also look into the other Break Nutrition podcasts - I know Tucker Goodrich and Gabor Erdosi recorded a very interesting discussion recently, and I'm going to see what else there is.
