    Mr. Nature:

    Do you think that omega 3 and 6 PUFAs are essential, and if so, will
    you state an hypothesis for this notion?

    Why are essential fatty acids essential?

    There is hardly any question that cannot be answered by doing a search
    in Google. The final search string appears to be as follows.

    synthesize linoleate OR linolenate "essential fatty acids" site:.edu

    In plain English, essential fatty acids are considered essential
    because they cannot be manufactured by the body (or are produced in
    such small quantities by your body that they must be supplemented by
    your diet).

    The technical reason is that human beings are mammals and ...
    http://72.14.207.104/search?q=cache:6KDT-8rhHSgJ:www.uwyo.edu/MolecBio/LectureNotes/MOLB4610/BIOCHEM_LECT08.ppt+synthesize++linoleate+OR+linolenate+%22essential+fatty+acids%22+site:.edu&hl=en
    "Linoleate [18:2; 9,12] & linolenate [18:3; 9,12,15] are essential
    fatty acids in mammals" because they are "precursors for arichidonate,
    prostaglandins, and thromboxanes."
    http://72.14.207.104/search?q=cache:xkGZwTaVMdwJ:courses.mcb.arizona.edu/462b/hallick/lipids/page7.html+synthesize++linoleate+OR+linolenate+%22essential+fatty+acids%22+site:.edu&hl=en

    Why?
    http://web.indstate.edu/thcme/mwking/lipid-synthesis.html
    "Since these enzymes cannot introduce sites of unsaturation beyond C9
    they cannot synthesize either linoleate (18:2D9, 12) or linolenate
    (18:3D9, 12, 15)."

    Again ...
    http://72.14.207.104/search?q=cache:J-clHikgOXYJ:www.cm.utexas.edu/CH369/Browning/chapter14/chapter14.htm+synthesize++linoleate+OR+linolenate+%22essential+fatty+acids%22+site:.edu&hl=en
    "animals cannot desaturate beyond D 9, must obtain those fatty acids in
    diet
    - linoleic and linolenic are essential fatty acids
    - - linoleic is precursor to archindonic which is precursor of
    prostaglandins"

    There are no citations to research on this issue because Montygram's
    definition of "basic sciences," like biochemistry, tells us so.

    Also ...
    http://web.indstate.edu/thcme/mwking/lipids.html
    "The majority of body fatty acids are acquired in the diet. However,
    the lipid biosynthetic capacity of the body (fatty acid synthase and
    other fatty acid modifying enzymes) can supply the body with all the
    various fatty acid structures needed. Two key exceptions to this are
    the highly unsaturated fatty acids know as linoleic acid and linolenic
    acid, containing unsaturation sites beyond carbons 9 and 10. These two
    fatty acids cannot be synthesized from precursors in the body, and are
    thus considered the essential fatty acids; essential in the sense that
    they must be provided in the diet. Since plants are capable of
    synthesizing linoleic and linolenic acid humans can aquire these fats
    by consuming a variety of plants or else by eating the meat of animals
    that have consumed these plant fats."

    Just thought that you might want to know about "basic science,"
    Montygram!

  2. Nobody doubts that humans don't synthesize omega 3s and 6s. Plants do
    because they are such biochemically active molecules that they can
    allow for very quick growth, which many plants need, due to predation
    or short growing seasons.

    Humans do synthesize omega 9 PUFAs (the Mead acid) if omega 3 and 6
    consumption is kept low. The Mead acid is metabolized into LTA3, which
    is much more stable biochemically. The metabolites of omega 3s and 6s
    are like medication for humans, though for plants and some animals in
    very cold climates, they are necessary.

    My post about the underlying hypothesis is the key. If you want to
    claim that adult humans (non-pregnant) have any need for omega 3s and
    6s, outside of emergency medicine (and other synthetic drugs are used
    there anyway), then you need to formulate a specific hypothesis, which
    would include:

    How much of each class is needed and in what form (linoleic and AA are
    both omega 6s, for example)?

    What will happen if one does not consume this amount, and how long will
    it take for the symptoms to appear?

    The answers need to be based upon on point experiments. The
    experimenst that have been used to justify some vague, non-scientific
    claim that omega 3s and 6s are essential actually demonstrate that they
    are not essential, unless one wants to define essential in a way that
    makes no sense, in which case human communication in general would
    break down completely.

    Since nobody wants to be specific, I will give you choices:

    1. Adult humans need at least 2 grams of omega 6s and at half a gram
    of omega 3s each day.

    2. Adults humans only need trace amounts of omega 3s and 6s.

    3. Adult humans need massive amounts of omega 3s and 6s due to
    supposed things like, "rapid DHA turnover in the brain," which some
    "experts" claim is true in "normal physiology."

    4. Omega 6s are needed, but omega 3s control "inflammation."

    If you can't choose one of the above, then you are clearly not serious
    about this claim, because you are unable to say anything about it that
    would aid a person in making decisions about what to do if it is
    correct.

    You can cite all the textbooks you want. In some textbooks, a large
    percentage of the claims are either wrong or have not been demonstrated
    by on point experiments. In some cases, it does not matter much, as
    with vitamins that don't build up to toxic levels, so one can take a
    bit more than might be necessary and nothing negative will occur.
    Omega 6 PUFA metabolites, however, are the direct cause of many cancers
    (see Jay Whelan's work on colon cancer, for example), and thus one
    needs to know exactly what the "essential fatty acid" hypothesis is.
    I'm sure you, being such a forthright person, will at least do the
    readers a favor and select one of the "essential fatty acid" options I
    have articulted, and we can proceed for there.

    I am waiting...

    Well, I hate to inform you but you have been claiming that for the last
    3 years. Why do you think that everybody thinks that you are so crazy?

    I will cite my own web page.
    http://food.naturalhealthperspective.com/dgtable.html
    For the Omega-3's 2.5% of total calories. Figuring on one week of 3
    meals of fish will give 17.5% for the week or 350 calories (2,000
    calories a day) or 38.889 grams divided by 3 meals gives 12.96 grams of
    Omega-3 fat per fish meal. Or, that works out to 5.556 grams a day.
    Of course, these are maximum figures.

    Per my web page, the minimum amount (ie, 2 meals a week) would be 3/5's
    the maximum amount or approximately 3.333 grams a day.

    Plant sources of omega-3's are are optional. But, you need to consume
    10 times as much to replace eating fish.

    Balance will come from Omega-6's (ie, 2.5%). If you consume process
    food, you are going to get PUFAs in your diet. That is how I figured
    it. There is no requirement to add Omega-6's. Just try to minimize
    total PUFA consumption to 5% of total calories, with Omega-3's
    providing approximately 50% of that total.

    Citations are on my web page.

    Now, when will I receive the $10,000?

    Stable? Please elaborate. Series 3 (from Mead acid) and series 5
    leukotrienes (from EPA) are less inflammatory than series 4 leukotrienes
    (from AA), that's what counts, not your vague "stableness",

    Quoted message said:

    Really? DHA is required by the brain and retina, DHA, EPA and AA as
    structural elements of cell membranes, AA is needed for the synthesis of
    eicosanoids such as prostaglandins (some of which are antiinflammatory, for
    example prostacyclin (PGI2)), thromboxanes A2 (and B2;
    <http://en.wikipedia.org/wiki/Thromboxane>😉 and leukotrienes (yes, they are
    necessary although too much is harmful), and DGLA (omega-6 fatty acid
    derived from omega 6 linoleic acid, sometimes called also DHGLA) is needed
    for the synthesis of antiinflammatory prostaglandin E1 and thromboxane A1
    (<http://www.uspharmacist.com/oldformat.asp?url=newlook/files/Alte/ACF301B.cfm&pub_id=8&article_id=147>😉.

    To summarize: Humans cannot synthetize neither omega 3s nor omega 6s, which
    are necessary for humans, in other words omega 3s and omega 6s fulfill the
    definition of essentiality. Because humans can derive all longer chain omega
    3s from alpha-linolenic acid and all longer chain omega 6s from linoleic
    acid, only alpha-linolenic and linoleic acid are called essential.

  5. For those who are unfamiliar with the technical language:

    Chemists and biochemists talk in terms of activity. In whole foods
    that have been processed into "supplements," for example, it's
    important to know what the active ingredient is. There is nothing
    vague about this. Mead acid and arachidonic acid do many of the same
    things, but arachidonic acid is much more powerful, more biochemically
    active. In this context, Mead acid is much more stable. Below is a
    study in which the authors make the point that erucic acid (found in
    large amounts in rapeseed oil and much smaller amounts in canola oil)
    is a very potent inhibitor of neutrophil elastase. Thus, in this
    context, eruic acid is very biochemically active. In another context,
    it might be regarded as very stable. Note that the authors say "The
    highly active erucic acid with an IC(50) value of 450 nM (elastase) is
    remarkable." "Remarkable" is not a scientific term, but in this
    context, it clearly means that they did not expect erucic acid to be
    this biochemically active in this experiment. There are over 92,000
    hits on google when one searches for the phrase "biochemical activity."
    There is nothing unusual about it; in fact, it is a term of art.

    Now you should be asking yourself, "why is this so important?"
    Biochemical activity comes at a price. It is not "all good," though it
    can have beneficial effects in particular contexts, such as when
    someone is very ill or injured and just needs to survive the night.
    Long term damage could be done, but ER doctors may think that it's
    worth the risk. This is not unusual. If you watch the TV show "ER,"
    you'll see them face this situation very often. Excess biochemical
    activity means vital biomolecules can get damaged and become
    dysfunctional, and also pathways can be shut down or turned on, when
    they should be turned off or enhanced. This is what happens with
    arachidonic acid in the context of many common cancers, as Jay Whelan
    has demonstrated over the last decade or so.

    One web site had a simple way of describing it, in terms of "exercise:"

    "1. Exercise acts as a stimulus for biochemical activity among body
    cells and fluids.

    2. The biochemical activity is destructive to the chemical make-up of
    body cells and fluids.

    3. The exercise is followed by proper nutritional intake and rest.

    4. The result from the combination of exercise stimulus, nutrition and
    rest is that there is an "overcompensating restoration" of the cells
    and biochemical fluids in the body.""

    Source:
    http://www.findarticles.com/p/articles/mi_m0675/is_n3_v15/ai_19408658

    This is their hypothesis about the "benefits" of exercise. I don't
    agree with it, but number 1 and 2 are accurate, in general, while 3
    depends upon what one considers "proper nutritional intake." Number 4
    is the most interesting. It's important for damaged and dysfunctional
    biomolecules, especially proteins, to be "recylced," so to speak.
    However, if the "exercise" is too intense, more damage will be done
    than good. If you don't expose your body to the exess biochemical
    activity in the first place (for instance, by taking several fish oil
    pills each day in an attempt to counteract your high omega 6 PUFA
    diet), then you probably don't need to do much "exercise." If you do
    exercise, studies have found that raisins, due to their antioxidant
    makeup, are helpful for athletes, in terms of limiting free radical
    damage done during the stressful activity (whatever it is). Thus, my
    question is, "then why do the exercise in the first place?"

    Nothing seems to glycate proteins in a damaging way than arachidonic
    acid, as studies have found, so as I've said many times here, it's a
    matter of seeking to correct the epiphenomeon, rather than the root
    cause. Just stay away from foods that are highly biochemically
    unstable and you will "addition by subtraction." Note that I do not
    advocate eating foods high in Mead acid either. It is a PUFA and is
    less stable than saturated fatty acids. I am saying to let your body
    make its owns PUFAs as is needed. Since it's unlikely you will find
    any food high in Mead acid (due to the stuff they feed livestock these
    days), you probably shouldn't worry about this possibility at all, but
    it's a useful point to make in the context of this issue.

    Here's the study I quoted above, for those who are interested:

    Planta Med. 2002 Sep;68(9):767-9.
    "Free fatty acids inhibit the activity of Clostridium histolyticum
    collagenase and human neutrophil elastase."

    Rennert B, Melzig MF.

    Institut fur Pharmazie, Humboldt-Universitat zu Berlin, Goethestr. 54,
    D-13086 Berlin, Germany.

    We investigated the ability of free fatty acids to inhibit the activity
    of Clostridium histolyticum collagenase (EC 3.4.24.3) and human
    neutrophil elastase (EC 3.4.21.37). We determined the activity of
    collagenase by degradation of resorufin-labeled casein
    fluorimetrically. The determination of the elastase activity was
    performed by a spectrophotometric method using a 4-nitroanilide peptide
    substrate. We found that most of the tested fatty acids inhibited
    collagenase at concentrations between 50 microM and 500 microM. For
    elastase we found an inhibition of the activity at concentrations
    between 500 nM and 50 microM. The most potent inhibitory fatty acids of
    both enzymes differed. Thus, as a result for collagenase we can assume
    that the saturated fatty acids with C(16)-C(19) were the most potent
    ones. For elastase the inhibition rate of unsaturated acids was much
    higher than the rate of the saturated ones. The highly active erucic
    acid with an IC(50) value of 450 nM (elastase) is remarkable.

  6. Where is the evidence for all your claims, Matti. Yes, I understand
    that some "expert" made a claim or that a textbook says that "we think
    X is true, but we're not sure," but science requires that the
    scientific method be followed, and you are demonstrating very clearly
    that this is not the case for the "essential fatty acid" claim, because
    you never cite any on point scientific paper in this context that is
    supportive. Do you even realize that, or are you so deluded with a
    kind of religious fervor that you can't even think straight at this
    point?

    The body makes perfectly fine metabolites from Mead acid, as I have
    personally discovered over the last several years. AA metabolites are
    very dangerous, as hundreds of studies now demonstrate. Just do a
    pubmed.com search for arachidonic LTB4 cancer or arachidonic PGE2
    cancer and you (or anyone else) will see what I mean.

    I feel for your lack of scientific understanding, but the health of
    others should not be jeopardized by your irresponsible claims.

    I welcome an experimental challenge to my claims, and have proposed
    several possibilities, but you can't even cite one piece of on point
    evidence your claims. Where are the loads of evidence you mention?
    I've seen that evidence, and it demonstrates that omega 3 and 6 PUFAs
    are definitely not esssential. If they were, no animals would have
    been born healthy. If you think I am wrong, take me up on my
    exeperiment offer. Loser must pay for all expenses and admit in a
    written statement, notarized and sent by certified mail to the winner,
    that he or she is wrong.

    If not, then at least articulate a clear and detailed hypothesis, then
    we can proceed from there. You are just "blowing smoke around" at this
    point. You propose no experiment, you can't articulate a specific
    hypothesis, and your evidenve contradicts the most basic of your
    claims. Do you realize that there is no doubt that the Mead acid is
    metabolized into molecules that clot blood, etc., which is the purpose
    of a stressor-induced, long chain PUFA in human cells, and you don't
    provide any evidence that the Mead acid can't get that job done. Fatty
    acid "expert" Mary Enig called the Mead acid a "filler," but again,
    where is the evidence that it is not a healthy "filler?" She said the
    experimental animals don't live as long on the Mead acid, but I have
    seen no evidence of this. I'm sure you, Matti, would love to take this
    opportunity to find such a study and cite it here. Can you at least do
    that?

    If you can't, or if you won't explain what the "essential fatty acid"
    hypothesis is, I will start a new thread, and no longer post to this
    one, as I said before. I'm trying to be fair here and address your
    points, but so far, there's nothing scientific in your post to address.

    And if you are proposing a new experimental offer about the Mead acid
    levels in my body, I will gladly take you up on that offer, so go ahead
    and make it clear. Loser must pay for all expenses and admit he is
    wrong. But try to think a bit here, Matti. If someone like myself,
    who consciously has avoided omega 3s and 6s for about 4 years (except
    in unavoidable trace amounts) and in light of the dangers posed by AA
    and EPA/DHA excess, why should an "expert" tell anyone to make sure
    that they are consuming enough of them? If I am getting enough, then
    surely the only one who isn't is a person who is on some oddball and
    totally fat free diet. Do you realize this? I have seen, however,
    clear evidence that the Mead acid has taken over: 1. my keloid, which
    I've had since I was a teenager, is nearly gone, and this is consistent
    with the evidence connecting AA with keloids. 2. Cuts form rubbery
    scabs quickly, then the wound heals much slower, but with no scarring.
    3. No or hardly any symptoms when I get a cold that's going around,
    which has been very rare over the last few years, though I used to get
    at least 2 colds a year while on the old diet high in omega 3s and 6s.
    4. I feel burns the same way, but there is no blistering. I just put
    a little ice on it for 20 minutes or so and there's no problem.

    I don't have to demonstrate anything. I am saying to allow your body
    to do what it wants to do naturally, until there is evidence that
    demonstrates that this is not the best thing to do. This is the most
    responsible way of dealing with such situations. If a snake oil
    salesman comes to your door and tells you that you need the snake oil
    because it is "essential," do you say, "oh, thanks for telling me, I'll
    take a dozen bottles to start?" I don't know about you, Matti, but
    most people would say "no" in a resounding fashion.

    Once again, I am waiting for an intelligent, appropriate response...

  7. One other thing worth considering:

    If I am not "EFAD" at this point, then the literature you cite as
    your "evidence" is totally wrong on one of, if not the most
    important point here. They claim that a diet such as mine should lead
    to "EFAD" in about 2 weeks. Even if they are badly wrong, and it
    takes 2 months, I still should have been "EFAD" more than 2 years
    ago! If you think they are correct about their claims, then you are
    caught in a logical contradiction. This is why I am asking for the
    hypothesis, that is, because no matter how you phrase it, it is a
    logical contradiction when one looks at the evidence. This is why
    people like yourself fear stating exactly what the hypothesis is. You
    know that you will be trapped like the proverbial rat.

    proove that. post a lab results of a test.
    I doubt you have even elevated mead levels from the diet you posted.
