Too many PUFAs (polyunsaturated fatty acids). More info here: http://180degreehealth.blogspot.com/2010/01/how-to-reduce-omega-6-tissue.html#

I did do the liver cleanse yes! It's pretty intense but I believe in the benefits. I think I did see a difference in my skin but not as much as with cod liver oil. However I think it's great for lots of other complaints eg allergies. I haven't done it for a couple of years because you need the time to do the apple juice fast beforehand. And well, drinking olive oil and grapefruit juice is not much fun. :-)

The WAPF site is always breaking I know! Try going through the main site and then doing a search, eg http://westonaprice.org/component/finder/search?q=acne
