    I take it that we are all posting from the standpoint that 'essential' only means that the body is unable to synthesise its own O3 and 6, rather than it being ' essential' for life?? Seems like the word is being used interchangeably her

    100 calories of brown rice has 260mg, wheat flour has 230mg which isn't much, so why is the standard diet high in 6's? Is it just the canola oil and similar oils? So why do we avoid grains then apart from the glucose?

The study that claimed PUFA's were essential that was conducted many decades ago was later debunked - it turned out to be a B vitamin deficiency brought on by the 0 fat diet. Since B vitamins are incidental to meats, simply supplementing with B vitamins corrected the issue. That hasn't stopped the seed oil industry from spreading EFA lies, though. Omega 6, omega 3, the less the better I say.

    Another odd thing I was thinking about today, wont the n3s & 6s in fish and other animal protein be oxidized when we cook it, losing any health benefits that the oils would have provided?

    Nope. In whole foods, the oils are usually pretty well protected. If you isolate the oils and THEN heat them, you run into trouble. See the second question in this post:

    According to nutrition textbooks, saturated fats and cholesterol cause heart disease. Most things printed in textbooks are eventually proven wrong.

    Fats can be synthesized in the body just like glucose can be. Technically, all you need to consume is protein. The glucose your brain needs can be synthesized from the amino acids, and the fats you need can be synthesized from the glucose. Of course, it's ideal to eat both fat AND carbohydrate and not force your body to convert, but I'm simply making the case that the body can generally synthesize what it needs. People taking fish oil supplements to "balance their n3 : n6 ratio" are really just ingesting rancid varnish.

    I glanced at this post because a couple months back, I saw something on Paleohacks about LA deficiency posted by one of the more involved members (Travis Culp), but I never saw any references. I'd always heard that omega-6 was the devill more or less, so I wanted to see something to back up Travis's claims before I started eating nuts by the handful or whatever.

    I could only find short answers and comments from Travis on the subject, but here is a thread with some of the same arguments presented: Is there a minimum requirement of Omega 6 fatty acids? - PaleoHacks.com

    By the way, a 0 fat diet is IMPOSSIBLE. Even fruits and plants have fat. If you eat like this crazy dude that ingests 30 bananas a day, you get your fat
    I realize a 0 fat diet is impossible for us, but it can be done in a laboratory setting. When they do these rat studies, they basically feed them refined oils and sugars fortified with vitamins and minerals.

    That's how they skew these "high fat diet = heart disease" studies. They take refined soybean oil, crush up vitamins in it, feed it to rats, they get atherosclerosis and put on body fat and they proclaim "high fat diets cause heart disease and obesity!" No buddy, refined high PUFA vegetable oils do. Do that same study with ghee or coconut oil and it probably will be remarkably different. Or, even scarier, use REAL FOOD high in fat, like egg yolks and bone marrow. But that wouldn't give them the result they want...sigh.

    I don't think it's possible to be deficient in Omega 6 fatty acids on a diet of real food.

    I don't even think that is proven. I have yet to see any proof showing the human body cannot synthesize omega 3 and omega 6. As far as I'm concerned, this is one of those myths that everyone assumes is true but no one can prove.

    This is a summary. Secondary information. It is essentially a textbook excerpt. I'm talking about an actual study - primary information - showing the human body cannot do this. The information that surrounds "EFA's" seem to be more myth than fact.

    Essential Fatty Acids - Essential fatty acids are, according to the textbooks, linoleic acid and alpha linolenic acid, and they are supposed to have the status of "vitamins," which must be taken in the diet to make life possible. However, we are able to synthesize our own unsaturated fats when we don't eat the "EFA," so they are not "essential." The term thus appears to be a misnomer.
