First of all, let me come clean and say that I am a layman, so I don’t have expertise in these subjects. So, why did I post this?
(1) The arguments in favor of saturated fats (and reduction of PUFA)that the biochemist Ray Peat ( http://raypeat.com/articles/ ), biochemist Lita Lee ( http://www.litalee.com/shopdisplaycategories.asp?id=19&cat=Articles ) and the above guy make a lot of sense to me. One can not argue that he doesn’t cite his share of studies.
That, of course, does not mean he is right (nor that he is wrong). I admittedly lack the expertise to judge those studies but, as I said, I found their argument compelling enough for me to experiment on myself and share with others here so that they can choose, or not choose, to investigate these ideas further.
(2) I have to go on my own anecdotal experience. For example, when I got into taking fish oil, I can honestly say that, after a few months, I saw no benefits. Maybe there were benefits, but I was unable to detect them. However, when I started taking coconut oil, I did notice, after a month, some positive, tangible results.
Aside from, taking coconut oil, there were no dramatic changes in my diet. My bodyfat went visibly down. No, I did not have it measured, but a little bit of tummy fat that had been impossible to get rid of (even though my estradiol levels were very good) noticeably diminished. I don’t know if it was the coconut oil, the reduction of PUFAs, or both, but I am convinced that it was one of those, because there were no other changes to diet.
Anyway, one of the arguements of the pro-saturated fa partisans is that saturated fats, particularly coconut oil, improves thyroid and raises metabolic rate. My experience suggests that this might be true.
Now it could be argued that these are just anecdotal tidbits and that saturated fat could cause me problems down the line. Maybe. But one has to act upon the evidence one has, and, as I wrote above, I find the theory compelling and have
the results of my own, obviously limited, experience.
- As far as I can tell, our ancestors were eating more saturated fats and less PUFAs than we do. First of all, it was highly uneconomical for them to make large quantities of seed and soy oils
and, correct me if I am wrong, but they would have to eat an inhuman amount of seeds and nuts to extract the amount of PUFAs we get from our daily eating of canola, safflower, soy and other vegetable oils. The question isn’t, can we eat PUFAs at all. Obviously we can and have.
My question is, can we eat, without dire consequence, the large amounts that are present in the American diet (upon the recommendations of the American Medical establishment)? Perhaps our bodies are ill equipped to handles these amounts of PUFAs, since traditionally we have eaten more saturated fats and less PUFAs. The arguments made by Peat, Lee and the author of the linked blog point to this.
By the way, I am eating more or less 4 or 5 tablespoons of coconut oil a day, and trying to cook with coconut oil, butter or olive oil (olive oil is of course neither a saturated fat, nor a PUFA, but a Monounsaturated fat (MUFA), which according to these authors is not noxious like the seed oils.
