PUFA consumption chart on CNN's "Fed Up: America's Killer Diet."

monty1945@lycos.com - 23 Sep 2007 05:31 GMT I couldn't see the exact date (quite a distance away from a small TV - will get back if I catch in on rerun), but from the mid twentieth century to the present, consumption of omega 6 PUFAs in the USA rose tremendously. I've pointed that out this was noted in the book, "Diet and Health," by the National Research Council (published in the late 1980s).
But rather than interpret this to mean that PUFA consumption should be kept very low, which is the only interpretation that one can be sure of, omega 3 consumption was advocated. I did not see the entire show, but it did not appear that they were going to explain that dietary omega 6s will be made into the very dangerous arachidonic acid molecule once a person eats too much omega 6 PUFAs. This, in turn, leads to all kinds of "inflammatory" conditions, of which obesity is one (in perhaps a majority of obesity cases in the USA today). Watch an old movie, prior to about 1950, and you will see that the middle- aged and older people do not have that puffy/inflamed look, nor do they have that "dripping skin" face, both of which are very common these days.
So CNN, despite all the useless or misleading dietary advice I've seen before, finally presented the one piece of raw data that is indisputable, entirely consistent with the molecular-level evidence, and makes it clear what everyone should do immediately in order to greatly lower their risk of all kinds of "chronic diseases."
Too bad the narrator did not have the common sense to point this out to the viewers.
Ron Peterson - 23 Sep 2007 07:01 GMT CNN said today: "Our brains are composed of fatty acids, and an absence of omega-3 fatty acids can actually change our behavior, according to Hibbeln.
Hibbeln's research suggests diets containing omega-3 fatty acids found in fish reduce depression, aggression and anger, while improving mental well-being."

monty1945@lycos.com - 23 Sep 2007 07:35 GMT Yes, Ron, and as I've told you many times before, there is no direct evidence that omega 3s and/or omega 6s are essential. In fact, the body makes a PUFA called the Mead acid, which does what arachidonic acid does, only in a much safer way. Actually, I got a nasty cut the other day which punctured a vein. It stopped bleeding quickly, and the inflammation was gone within a couple of hours. If I had arachidonic acid in my cells, as most Americans do, the inflammation would persist (as it used to when I got even a paper cut prior to a few years ago, when I had arachidonic acid in my cells), and this is the underlying cause of "heart disease," cancer, diabetes, AD, etc.
Now I've asked to several times to address the direct evidence, but instead you cite evidence that is either highly misleading (such as when you cited a Malaysian study, when in fact this society is now consuming a much more Western diet than other Asian peoples who are still eating a lot of coconut products) or is in some way not relevant. One example is the many fish oil studies, which are contextual and short-term. They appear to show a "benefit," but this is only due to its action against arachidonic acid metabolites, and fish oil has very toxic qualities for a "food" item. I will ask the key question again: How can people like myself (and many Asians) consume a diet very low in PUFAs yet very high in SFAs and still be healthy (in fact, I "cured" myself of a terrible wasting disorder on my present diet)? If SFAs are so unhealthy where are all the "diseases" people like you claim will occur? Did you see the film, "Supersize Me?" If you did, you saw how Spurlock deteriorated rapidly on his omega 6 rich diet. If the SFAs were so unhealthy, I would have had a similar experience back in 2002 or 2003 - don't you realize that simple fact?
I don't understand people like you, Ron - do you consider yourself a scientist or not? If so, how can you simply ignore evidence you don't like? Do you feel that you are bound by any ethical standards at all?
Let's get back to the point of the original post now; did you or did you not see how omega 6 PUFA consumption increased nearly vertically since the early 1960s (I saw the show again and it appeared to show the rise really going vertical around 1960s or a year or so later)? If so, why would anyone advise that people consume omega 3s or 6s? Where is your evidence that it is "essential?" And how do you explain the direct refutation of this claim by M.I.T. researchers in the 1940s?
I'm more than willing to do some experiments that are on point, if you wish, with the stipulation that the "loser" pays for all expenses. If you are so sure of your notions, Ron, why not take me up on one of my offers? I'm willing to negotiate the exact experimental apparatus, and you have nothing to lose, since you can simply refuse in the end. Do you or do you not understand that if a direct experiment can be conducted, it should be, because it represents the strongest possible evidence?
I understand that "some people say" that omega 3s and 6s are "essential," but since researchers have refuted this long ago, why do you care about what "some people say," and in fact feel the need to be one of those people? Have you conducted any experiments yourself? If not, why have you decided that some research deserves to be promoted while other research should be totally ignored? As I've pointed out, there are indeed studies in which the author claims that there is "rapid DHA turnover in the brain." This claim is simply impossible, since I avoid all sources of omega 3s, and have since 2001. I also saw a great grandfather live to be over 100 with no source of omega 3s. Hopefully, some day you will realize that just because a person with a Ph.D. after his name makes a statement, that does not mean it is accurate. Fortunately, I was trained to examine evidence critically, and will continue to point out that there is only one reasonable interpretation of the evidence when viewed comprehensively, though I fear you will continue to "cherry pick" what is consistent with your pre-conceived notions, thereby misleading people into the realm of "chronic disease."

monty1945@lycos.com - 23 Sep 2007 08:04 GMT Well, if a person knows that omega 3s have powerful toxic effects and give this to prisoner, this is something quite unethical (perhaps "evil," depending upon how one defines it). Again, it would not be expensive or difficult to give them "junk food" that will get the arachidonic acid out of their cells safely. Cool whip is all saturated, and I've seen plenty of cookies that were almost entirely saturated fatty acids (of the fat content of course). Creating a monster to kill a monster is a zero sum game, isn't it?

The healthandage website states: "A British study published in 2002 provides some corroboration for the role of omega-3 fatty acids in antisocial and violent behavior1 Over 230 young prisoners were given nutritional supplements, including omega-3 and omega-6 fatty acids, or placebo, in a randomized fashion for 2 weeks. During this time the those receiving the supplement capsules committed 26% fewer offences than those taking the placebo capsules."
I interpret this to mean that omega 3 fatty acids improve mental health.
