Guest guest Posted May 20, 2008 Report Share Posted May 20, 2008 Gentlemen, In all honesty, I think I will be wondering what my SFA, MUFA, SUFA ratios are for quite some time in regards to overall triglycerides & other fat mechanisms. Just, Jim Masterjohn <chrismasterjohn@...> wrote: , > Do you have any hard data on the risks posed by high consumption of > MUFA?

I haven't seen a lot of info comparing MUFA to SFA but what I've seen indicates that they are similar with respect to oxidative stress. A very high MUFA intake, especially with low PUFA intake (ratio of >10:1) will elevate Mead acid, which might be good or bad depending on whether it does anything important. I suspect it's easier to desaturate SFA to MUFA than to saturated MUFA to SFA, so if one is consuming way too much MUFA as a proportion of calories I suppose this could lead to a relative deficiency in SFA. On the other hand, it might be that it is easier to synthesize MUFA from carb than from SFA, since the delta-9 desaturase is regulated as part of the network of fatty acid synthesis enzymes, so it is probably similarly harmful to consume way too much SFA relative to MUFA. So I think it makes the most sense to consume somewhere around half and half, which seems to be roughly what you get from ruminant fat, which I think is somewhat of an indication of the mammalian need for the two types.

In a way it's kind of a moot point because your body naturally makes lots of MUFA. The main vulnerable carbon for oxidation is the one that is single-bonded to two adjascent carbons that have double bonds on each side, not the carbon of the double bond itself, and MUFA doesn't have such a carbon. That makes it easier to believe for me, especially since I had wrongly had the impression for years that it was the carbon actually participating in the double bond that gets oxidized. >> So I think it makes the most sense to consume somewhere around half >> and half, which seems to be roughly what you get from ruminant fat, >> which I think is somewhat of an indication of the mammalian need for >> the two types. > This seems like a reasonable guess, so it would seem that it might be > a good idea to balance any highly-saturated oils (like coconut) with > some highly-mono-unsaturated oils (like macadamia) if such oils make > up a significant portion of calories (in an attempt to drop PUFA down > to 1% of calories on a high-fat diet, for example). I agree. On a lower-fat diet like the one Ray Peat recommends (apparently 25% fat according to second-hand source), using pure coconut oil wouldn't present that problem because you'd have plenty of carbs to stimulate MUFA production but on a high-fat diet I would shoot for the mix. Doing so would mimic animal fat but without the excess of PUFA that occurs when the total fat goes very high. Chris Quote Link to comment Share on other sites More sharing options...

I imagine a mix since I would think pigs would be like most other mammals (animals?) in needing such a mix, and because I think the basic fatty acid synthesis machinery is conserved across all mammals (which makes palmitate in the mitochondria and then modifies it by elongation and/or desaturation in the ER as needed).

Yeah, that's certainly true, but never let it be said that I'm not interested in something just because it's moot. <g> > I agree.

Might it be wise to consume some extra MUFA on a high-fat diet in which most of the fat comes from dairy, in which there's a little more than twice as much SFA as there is MUFA? - Quote Link to comment Share on other sites More sharing options...

If the mixture is in roughly the same proportion as it is in other mammals, then it would seem that pork and lard might be rendered just as safe as beef fat with the correct feed. Too bad no such pork is available around here. <g> - Quote Link to comment Share on other sites More sharing options...

Well this is just guesswork but it sounds like that might be a good idea. Especially if you're using a lot of cream, so that you have a much higher fat-to-carb ratio than the calf would be getting.

I don't know. I wasn't thinking of anything in particular just agreeing with you but noting that another poster (who doesn't post here but I think lurks) seems to think it is doable, although my own personal take is only if you dramatically lower the animal fats and increase the low-pufa nut/seed oils. -- I will say that unless one is in some kind of daily, personal dynamic, be it marriage or monasticism, one will never truly see themselves.

Guest guest Posted May 21, 2008 Report Share Posted May 21, 2008 Hi, As a fairly new member here, I am not sure what balance to strive for with fats, my knowledge is limited. I think we all agree that it is about balance, right? It is known that fats help transport vitamins A,D,E, & K. Fat is known to help build brain & nerve tissue at the cellular level. Fat maintains skin, hair & nails. And they can provide energy for low intensity sustained workouts. For me, fat simply makes food smell & taste good & helps me feel full longer since fats take longer to digest. Unfortunately fats frequently lead to excessive caloric intake for me, probably because fats provide twice as many calories per gram as carbs or proteins causing me to gain weight. Fats are fabulous! They maintain body heat, protect vital organs, & give energy to adolescence & expectant mothers alike. The complicated ratios in SFA, Trans Fats, PUFA(omega 3 & 6), & MUFA can be a bit overwhelming to me at times. I leave that to the experts such as the AHA, ADA, & the ACS.

I leave that to the experts such as > the AHA, ADA, & the ACS. Well that souds like a total and absolute dietary disaster. I don't know how the ACS is but if they recommend anything like what the AHA and ADA recommends I think you're in trouble. You don't have to calculate anything. Just adjust what you consider " good " and bad " accordingly: Fats to use freely: butter, tallow, lamb fat, coconut oil, macadamia nut oil Fats to use regularly in small amounts: egg yolks (three a day), high-vitamin cod liver oil (1/2 tsp/day) Fats that are ok to use in moderation: lard, olive oil, red palm oil Fats that are ok to compromise with sometimes: high-oleic safflower oil, high-oleic sunflower oil Fats that should not be used at all: soybean oil, canola oil, safflower oil, sunflower oil, flax oil, any oils high in PUFA.

I think ghee would probably work best, although coconut oil is good. I left out ghee but I guess it is included in butter. Chris Quote Link to comment Share on other sites More sharing options...

Yeah, in my case I get the vast majority of my dairy fat from heavy cream, and heavy cream is undoubtedly my primary fat source. I've been sort of wondering whether I should try to incorporate some regular macadamia oil into my diet somehow; I guess now I'll make a point of it. - Quote Link to comment Share on other sites More sharing options...

The AHA gets a huge amount of its funding by selling its heart-healthy seal to manufacturers of processed junk food. I don't know if they're being " targeted " so much as having their own heavy-hitting marketing campaign. They call themselves " non-profit " but there isn't much difference between a president who makes >$600,000/yr to make selling their " non-profit " seal bring in the big bucks and a CEO who makes the same amount of money selling lots of... cars, or whatever else. They also market junk science to get government funding. When explaining how they created the myth that heart disease has been declining since they have started the campaign against cholesterol and saturated fat, the president of the AHA stated in the Wall Street Journal, as quoted in Colpo's _The Great Cholesterol Con_, " Our philosophy was that to get more money from politicians, we had to show that good things were happening.

Guest guest Posted May 22, 2008 Report Share Posted May 22, 2008 , A month or so ago you or another member provided a link to the Taubes interview on Good Calories Bad Calories, it was great! It shatters the myth of government funded calorie, cholesterol, low-fat, etc. as mere propaganda. Since then I have blasted other groups with the Good-Bad concepts, not always well received at first, but insightful once anyone starts to think about it, especially considering that most of the regimes out there are all calorie focused. The excerpt you quoted from me was was from someone else caloric input & more of a vain attempt to achieve so sort of balance to it all, as I am easily overwhelmed at times. How would T., a journalist, term the amount of food eaten, simply as a portion, combined, or what? Refresh me on that one, ok. Just, Jim <mattandgina@...> wrote: --- In , Igo <jimi761@...> wrote: >Unfortunately fats frequently lead to excessive caloric intake for me, >probably because fats provide twice as many calories per gram as carbs >or proteins causing me to gain weight. Jim, I think you should drop everything and read " Good Calories, Bad Calories " by Taubes. He basically disproves your above statment. Not all calories are the same and fat does not make you fat because it does not trigger the release of insulin, which is the only mechanism by which the body stores fat. Only sugars and grain-based carbs trigger insulin. When you stop/decrease carb intake you make your body fat available to be burned, and without the need to excercise. Anyway, he goes much more in-depth than this. This is why low-carb diets work! If you go back into the group message archives you can find some links to videos of Taubes giving lectures on this subject. I HIGHLY recommend watching them. He's quite brilliant, IMHO.
