Saturated fat interferes with essential fatty acid metabolism?

Answered on August 19, 2014
Created April 13, 2012 at 7:48 PM

I forget that I'm in a bit of a saturated fat tolerant bubble sometimes.

I was chatting with someone who also has an interest in paleo but wasn't so keen on saturated fat intake (maybe only read Cordain, I don't know) mentioned this to me, and I felt kinda like a dodo not even having heard of such a theory. I wanted to continue the conversation, but wasn't feeling like enough of a smarty pants to hold my own without knowing more about what I was talking about.

Can anyone explain where this theory comes from, or what kind of saturated fatty acid might've been implicated here?

I found that on the WAPF site, just didn't know what to look for yet. Dr. Mary Enig is pretty awesome.

Hot damn...good find on that study! I am high fiving you through the screen right now.

I can't remember where I read it- possibly Ray Peat- but it was something about how coconut oil fed animals rather rapidly develop EFA deficiency. Interesting question though.

Never heard anything like this before besides that animals fed coconut oil develop EFA deficiency rather rapidly. I don't remember where I read it though. I have read cordain, and I am a fan of his. I eat lean meats, eggs, fish, mixed nuts, olive oil, and avocado for fat. I'll eat small amounts of dairy fat every now and again if I'm at a French Bistro or something.

I would say this is a moot point - all of two essential fatty acids (ALA and LA) are going to likely be eaten alongside SFAs in nature. If they are not eaten alongside SFAs from one meal, then it's still safe to say they will be eaten with plenty of other FAs, since ALA and LA FAs aren't eaten in significant quantity in nature alone. SFAs don't really play into this at all.

Oh, wow - I found this study from 1959 that says that SFAs with EFAs stimulate better/faster growth than just EFAs supplemented alone. In rats.

So, I suppose there's some (old) evidence to support that fact that SFAs actually help to metabolize EFAs.

I found this little gem on the Weston A Price Foundation site in a response to Ray Peat.

"Finally, it should be stressed that certain components of the diet actually reduce (but do not eliminate) our requirements for EFAs. The main one is saturated fatty acids which help us conserve EFAs and put them in the tissues where they belong. Some studies indicate that vitamin B6 can ameliorate the problems caused by EFA deficiency, possibly by helping us use them more efficiently.

This article appeared in Wise Traditions in Food, Farming and the Healing Arts, the quarterly magazine of the Weston A. Price Foundation, Spring 2005.
