It's also an oil with far too much PUFAs for me, similar to canola oil (32% PUFAs or so). I don't eat oil with more PUFA than palm oil, olive oil, avocados, and hazelnuts (7-14% PUFAs). Goose, duck, lamb, and pork are also right in that range. Ghee has enough PUFA for a growing child or mother. With adults, the needs are negligible if they exist at all. No need to eat a vegetable oil to obtain them. Ghee, butter, and other animal fats would have more than enough IMO. Read Ray Peat's essays on fats and oils. His view is that it's best to limit all PUFAs equally. For example, he will eat shellfish, rather than salmons, because they have less PUFAs.<BR/><BR/>http://raypeat.com/articles/articles/fats-degeneration.shtml<BR/>http://raypeat.com/articles/nutrition/oils-in-context.shtml<BR/>http://raypeat.com/articles/articles/unsaturated-oils.shtml<BR/>http://raypeat.com/articles/articles/unsaturatedfats.shtmlAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-36840063.post-32839317847729426892008-06-03T23:00:00.000+00:002008-06-03T23:00:00.000+00:00This comment has been removed by the author.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-36840063.post-35423493723484094112008-06-02T08:10:00.000+00:002008-06-02T08:10:00.000+00:00Hi Gyan,These sorts of questions are why I'm worki...Hi Gyan,<BR/><BR/>These sorts of questions are why I'm working through Chris Masterjohn's ideas. For me it's a simple matter of deciding whether to take a fish oil supplement or not. Turning out to be quite interesting.<BR/><BR/>PeterPeterhttps://www.blogger.com/profile/14527788116058656094noreply@blogger.comtag:blogger.com,1999:blog-36840063.post-38431840913159360042008-06-02T03:49:00.000+00:002008-06-02T03:49:00.000+00:00This EFA question interests me since as semi-veget...This EFA question interests me since as semi-vegetarian low-carbs we consume a lot of ghee and raw coconut and for EFA we consume rapeseed oil which is our only vegetable fat (also traditional in our cooking).<BR/>So the question facing me is Can I eliminate rapeseed oil or what quantity is safe/desirable for me to consume. <BR/>I guess the topic is still a matter of deep controversy and there dont seem to be settled answers.Gyanhttps://www.blogger.com/profile/09941686166886986037noreply@blogger.comtag:blogger.com,1999:blog-36840063.post-48794979622518117522008-05-31T20:13:00.000+00:002008-05-31T20:13:00.000+00:00We can also synthesize omega-7 fat.

There are omega-7 PUFAs and omega-9 PUFAs, which occur naturally in our tissues. Ray Peat believes the Mead Acid (20:3 n-9) is more protective than omega-6 and omega-3.<BR/><BR/>On a diet low in PUFA (or with high ratios of SFAs/MUFAs/carbs/proteins to PUFA), the body starts producing more of the n-7 and n-9 series. The body can make eicosanoids from Mead Acid, since it is a 20-carbon PUFA. These eicosanoids have many unique properties that make them seem very beneficial and desirable.<BR/><BR/>http://forum.lowcarber.org/showpost.php?p=7121180&postcount=15Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-36840063.post-76443105451497095822008-05-30T07:23:00.000+00:002008-05-30T07:23:00.000+00:00Not recently and the ones there were were pretty r...Not recently and the ones there were were pretty rubbish. It's extra ordinarily difficult to produce a deficiency if you eat food, as opposed to what passes as food for many people today. Unfortunately it doesn't look as simple as "the need is low and there are no deficiencies".<BR/><BR/>PeterPeterhttps://www.blogger.com/profile/14527788116058656094noreply@blogger.comtag:blogger.com,1999:blog-36840063.post-51874566511208509862008-05-30T06:06:00.000+00:002008-05-30T06:06:00.000+00:00Is there an experiment crucis for Essential Fat Hy...Is there an experiment crucis for <BR/>Essential Fat Hypothesis?.<BR/>I merely ask out of curiosity and have no intellectual stake in the outcome.Gyanhttps://www.blogger.com/profile/09941686166886986037noreply@blogger.com
