High Omega-3, Low Omega-6 Diets Help Brains Recover

High Omega-3, Low Omega-6 Diets Help Brains Recover
April 2, 2016 Patrick Nemechek, D.O.

LA SourcesA growing body of scientific studies are suggesting that omega-3 fatty acids found in nuts, flax, wild fish, and grass fed beef can lead to the reduction of abnormal inflammation and restore a wide variety of cellular functioning within the body.

A recent study has shown that long term omega-3 fatty acid supplementation coupled with omega-6 fatty acid restriction improves cognitive function, reduces neuroinflammation (i.e., TNF-α expression), and increases brain cell production (i.e., neuronal progenitor proliferation) in mice. These results parallel and support the therapeutic benefit of high dose omega-3 therapy and omega-6 restricted diet recommended in the Autonomic Advantage Brain Recovery Program.

Omega-3 fatty acids (e.g., ALA, EPA, and DHA) are a variety of molecules important in the regulation of inflammation and cell function.  Omega-6 fatty acids (e.g., LA and AA) are also important in activating inflammation necessary for tissue repair and the maintenance of healthy tissue and organ function.  Maintaining a healthy ratio of omega-3:omega-6 fatty acids is critical in normal physical functioning, inflammation control, and long term health.

Unfortunately, Americans have experienced an explosive increase in their consumption of an omega-6 fatty acid called linoleic acid (LA), predominantly in the form of soy oil. In the 20th century, soy oil consumption increased 1000-fold.

The high intake of linoleic acid leads to decreased omega-3 levels by three mechanisms: 1) by the impairment of the conversion of ALA to EPA, 2) by the inhibition in production of DHA, and 3) by the competitive inhibition of EPA and DHA into the cell membranes.

The net effect of these changes has resulted in a significant increase in the omega-3:omega-6 ratio, and is believed to contribute a heightened level of persistent metabolic inflammation throughout the body.

Metabolic inflammation is rapidly being linked to the inability of the brain to recovery from traumatic brain injury in addition to other forms of neuronal damage such as emotional trauma, inflammatory insults, and stroke.  Metabolic inflammation is also linked to to a wide variety of illnesses including cardiovascular disease, cancer, diabetes mellitus, autoimmune disorders, Parkinson’s and Alzheimer’s disease.

Interestingly, this study also showed that an increase microglia number does not seem to be a major contributing factor, and that other mechanisms such as an increase neuronal progenitor cells and the reduction in CNS cytokine levels (TNF) activity may be more of a factor in cognitive decline and the neuroinflammatory disorders.

Understanding that the inflammatory cytokines, not the high numbers of microglia, are the problem points us in the direction that lowering inflammation is key to healing the brain after injury.

Other studies have shown that omega-3 supplementation reduces pathological microglia and astrocyte activation which occurs in post concussion syndrome, persistent traumatic brain injury, CTE, chronic depression, PTSD as well as Parkinson’s and Alzheimer’s disease.

In respect to patients recovering from traumatic brain injury (TBI), this study tells us that increasing omega-3 and reducing omega-6 fatty acid intakes can reduce the brain inflammation commonly found in TBI, can improve the ability to replace or repair damaged brain cells, and may potentially improve recovery of cognitive function.

Combining high omega-3 supplementation and low omega-6 fatty acid intakes with other forms of neuroinflammatory suppression is central to the success of the Autonomic Advantage Brain Recovery Program’s ability to reverse and restore underlying brain injury.

    Hello Dr, my son is 3.9yrs old and he is mild autistic and from last week he is on protocol and I have a lot of hope from this protocol after reading all the positive reviews about recovery, I have done all the food allergy test and he have allergy from most of the food we eat we r vegan and I have eliminated all allergic food from his diet. He was suffering from bad constipation and yesterday he got fever so I gave hi medicine and nw he got Dihhoria nw doc give him probiotics as well and I gave him one dose of probiotics also so my question is nw I have to stop inulin for a week .

      Food allergy testing is very inaccurate (lots of false positive results) when someone has bacterial overgrowth.

      You need to read the book because I believe one of the worst things you can do is give him probiotics.

    Thank you for the book! I d like to ask a question. We visited a biomedical doctor and she advised to send stool , urine and dried blood samples to the US (from Ireland). She advised that inulin would feed bad bacteria as well(if my son has too many of them) , the opposite what your book says. The tests would come back in a month but the inulin and fish oil arrives this week. Would you advise to start it anyway with small quantities? We are also trying to change our diet from lot of processed food to more gluten and casein free diet avoiding vegetable oils and eating plenty of fish. I wish to introduce gluten and milk again , but I would like to see tf taking them out from his diet would make any difference?! And I’m sure I wouldn’t be able to take them all out completely. Since I’m reading labels it’s in everything..
    He will be 3 next month , verbal but not conversational or functional. Just learnt phrases. No social skills . He doesn’t seem to have digestive issues… loves fruits especially berries, pasta, salmon…
    Sorry for the long message .
    Thank you for your reply!

      You are getting too much advice.

      There is no evidence that inulin feeds bad bacteria.

  3. Timea 1 year ago

    I just heard about this protocol and want to try it for my son. He will be 3 next month. We also have an appointment to a biomedical doctor. I purchased the book, but was unable to download it , hopefully you can send me the link again.
    I just read a comment below about demyelination in the brain-I’m dead for my right ear for 13 years and it continuously ringing as well, doctors said that’s the reason. Would this protocol help me to stop the ringing at least , even if I can’t get back the hearing ?
    Thank you for your reply!

    My son had his second brain MRI today for a suspected demyelination issue. Words used in report were that the abnormality was “less extensive” than previous MRI and “interval improvement.”

    He’s 2 and started Nemechek on January 18th. I’ve seen no observable gains but this report gives me hope.

      It could possible be improving already.

    Hello doctor. I read your book and im not sure if i understand everything 100% because my english is not so perfect. You write that when the child is using probiotic you should immediately stop the probiotics when giving inulin. My question is do you mean just probiotic like pills, powder etc or also to stop eating the food were probiotics are like yoghurt, milk, cheese etc? Because my daughter just gets vitamin d3 and k2 and is eating everything no special diet, also in kindergarten and i dont know if i have to change her diet when using the nemechek protocol. thank you

      Patrick Nemechek, D.O. 2 years ago

      Just the probiotic medications. Naturally fermented foods are ok to consume on my protocol.

    Hello, I started my 2 and a half year old son on the protocol about two weeks ago. We’ve already had excellent results…much more eye contact, more present, seems to feel better, is happier, etc. He’s sleeping much less also, but seems to have much more energy. What I’m wondering is if it is ok for him to still eat bacon? I get conflicting answers when I do an internet search.

  13. Thea Peluso 2 years ago

    Hello Dr. Nemechek –
    In your book for Autism and Developmental Disorders you provided a list of acceptable oils and those to avoid.
    + Is High Oleic Sunflower Oil (HOSO) acceptable? Could it be used in place of olive oil?
    You also explained that almonds, pecans, pistachios, cashews and walnuts are good sources of ALA.
    + Are the oils from these tree nuts acceptable or are they to be avoided?
    + If these tree nut oils separate out when making their nut butters, would you discard the oil or mix it back in?
    + Would you put macadamia nuts in the same group?
    Thank-you for the clarification!

    • Author
      Patrick Nemechek, D.O. 2 years ago

      Generally nuts, raw or dry-roasted are fine. Once generating them into butter, the products (additives, other oils) vary greatly and I leave that up to the consumer to decide.

      The amount of oleic acid in “high oleic” oils varies a great deal. Just stick to high quality olive oil, it works.

    • Elizabeth 2 years ago

      Hi Dr. Nemechek, I found this comment while searching to find your opinion on this, since I was just looking at a table that indicated high oleic sunflower and safflower oil actually are 75% oleic, the same as EVOO. Is that not true? Thanks!

    • Author
      Patrick Nemechek, D.O. 2 years ago

      Yes, a few of the high-oleic acid vegetable oils have the same oleic acid content.

      But many oils labeled “high oleic” are only 30-40% oleic acid. The term “high oleic” only means higher than the typical oils which run around 10-15% oleic acid.

      The term “high oleic” is unregulated and is in the eye of the beholder.

    Hi there! I had a stroke three years ago at 37. I have been left with complete numbness in my affected hand and near total loss of fine motor skills. I went through extensive occupational therapy and do daily weight-bearing exercises and “sensory stimulation” as directed by my therapists. A friend referred me to the Protocol and I just finished the 10-day course of rifaximin, as well as the DHA and EVOO. Would you expect to see improvement in my hemiparesis were I to continue? There seems to be so little research on nerve regrowth and regaining sensation, so I figured I have nothing to lose by trying.

    • Author
      Patrick Nemechek, D.O. 2 years ago

      I think you can experience more regeneration and function if the vagus nerve stimulation is added with rehabilitation exercises for your hand.

      You would need a visit in my Arizona office to obtain a VNS. I use this with other post stroke or spinal cord injury patients and have had a lot of success.

  18. Natalia Marmol 2 years ago

    Dear Dr Nemechek,
    I have a bit of a confusion regarding the issue of vegetable oils,
    In your book you mention that people following the protocol should avoid “bad Oils” ( sunflower, soy, corn, safflower, cottonseed, grapeseed, peanut, margarine, shortening),
    I understood that those oils needed to be removed from the diet in order to achieve the best result.
    Here is my confusion, I have been told that EVVO will counteract all the bad effects that the above oils have in our bodies and therefore there is no need to avoid them in our diet.

    I will be so grateful if you could please state whether the oils need to be removed from the diet or not
    ( I thought that Olive Oil was there to increase the omega 3 amounts to balance out the Omega 6-9 and to help out for any occasional intake of bad oils) .
    I just started my 4 year old in the protocol and I would like to do it right.

    • Author
      Patrick Nemechek, D.O. 2 years ago

      I recommend trying to get rid of these in the home as much as is practically possible.

      The EVOO will protect from any remaining omega-6 fatty acids getting in when eating out etc.

    Have you had any success in implementing your protocol in stroke patients? My father in law suffered a stroke last year. He is now struggling with aphasia, swallowing problems, emotional changes among other symptoms.

    • Author
      Patrick Nemechek, D.O. 3 years ago

      Yes but with a caveat.

      The process of having a stroke sets in place an inflammatory wave throughout the nervous system that can loosely be called an inflammatory concussion.

      Although the primary focus of the stroke may not fully recover, a great amount of the secondary events (memory, fatigue, altered balance) can.

      We also add in vagus nerve stimulation in effort to improve further stroke recovery via neuroplasticity.

    Forgot to add my name, show the previous comment shows up as Anonymous:) So repeating it here:

    Thank you Dr Nemechek.

    The only intestinal symptoms are diarrhea (Bristol type 6), multiple times a day with the fatigue, brain fog, lack of focus and interest. Have lost weight also over the past four years, I got much worse after an H Pylori treatment in 2014, though the IBS preceded that. I don’t have gas, bloating, or cramps or GERD. Mornings are the worst, most of the times, better by evening.

    I will just continue the protocol. Do you think I should add/remove anything else?

  22. MK 3 years ago

    Hello Dr Nemechek,
    I have IBS-D, with food intolerances, fatigue, brain fog, depression., lack of focus. I have tried various treatments and diets, and it seems like eating light food keeps things at bay a bit, but not a lot. My SIBO test showed 23 ppm, and I did take Rifaximin, but it didnt help as much as I thought it would, this was 6 months back. Blood tests for food intolerances found nothing, and doctors want me to go on low dose TCAs.

    I just started your protocol a week back and I will continue to do it for a bit. I am doing the adult protocol(3000mg DHA, 100mg flaxseed oil, inulin and 2 tbsp EVOO). Do you think doing Rifaximin with this protocol would be useful? Also. should I stay away from foods, or eat everything (other than Omega 6 oils which you recommend not having)? I would really really appreciate your answer, it has been too long without relief:)


    • Author
      Patrick Nemechek, D.O. 3 years ago

      Chronic intestinal symptoms are often from either from SIBO or autonomic dysfunction, and many patients have both.

      If you have both, rifaximin might help some but it leaves many intestinal symptoms unchanged (cramping or bloating for instance, or even GERD) because they may be from underlying autonomic dysfunction.

      These other symptoms will continue to improve over time with the protocol.

      I avoid all excess omega-6 FA in my food at home but I cannot avoid it when I eat out. The EVOO will protect from the omega-6 FA you ingest when eating in restaurants.

      BTW, inulin use after rifaximin may cause bloating.

    I hit my head pretty hard about 4 years ago and still get headaches in the area where I hit it. I’ve fallen into a vicious cycle of not eating fish after developing terrible histamine intolerance two years ago. Every time I eat fish, I feel nauseous, like vomiting, and get lightheaded within a few hours after. I get hives daily, sometimes from food, other times from no noticeable trigger. No IgE allergy to fish (or any other food) and I used to eat it all of the time. I know I need the omega-3s but am not sure how to get them.. just suffer through feeling poorly for a while, or is there a better solution? Would love to hear your thoughts. I personally feel like many of my symptoms can be attributed to SIBO but am not sure – I had a negative sibo test a little over a year ago.

    Hi Dr. Nemechek
    My son is 18 with Autism mostly non verbal but can say a few words. Understands everything. Last summer he started becoming aggressive. Long story short he has Pyroluria and is now in 7th month of treatment. It has been extremely rough but lowering. He has been tested gut dybosis with bacteria . I want to start your program but in his current pyroluria treatment it calls for evening primrose oil and to refrain from omega 3. I am so confused by this which one to keep or add. Also due to his age do I go directly to the perscriptiom? I have the inulin and actually gave him 1/ 8 tsp today. This past year his aggression has gotten worse and I am desperate to help him . I know pyroluria is a big reason but I know his gut is his real problem. I will add he has been off Risperidone going into month 2 after being on .05 for a couple years. I hope this isnt adding to his behavior. Just feeling lost today as to what to do.
    Thank you

    Dear Dr. Nemechek,
    In the last two years my 87 year old mother has gradually started to cognitively decline where it is frightening her and me. Two years ago she had a pace maker and stent procedure, also was placed on two lots of blood thinners. I have recently learnt through a radiologist that medications like blood thinners can cause memory to decline? A year ago she fell heavily into her bath tub and suffered concussion/amnesia and was hospitalized. At the time this was so severe it took her back 70years and lost the English language and who I was. Slowly over the months we have been able to bring her back but now she is showing signs of confusion worse than ever? Her decline is too quick and whilst I search for answers can Omega 3/6 help her or can you offer any suggestions how to help my mother from this cognitive decline? Just to add a neurologist has ruled out Dementia and Parkinson’s.
    Thank you for your valuable time.

    Hi Doctor,
    I’m really interested in your protocol for my son who is 2 and has autism. I’ve seen great gains through diet and a nutritionist has recommended fish oils and probiotics but I also have inulin which I’ll start once finished the probiotics. He’s taking the olive oil too. Could I ask if I should limit his egg and nut intake as they are a big part of his diet? (He’s dairy, gluten and sugar free)
    Thank you

      Most children are able to discontinue all food restrictions after stabilizing the bacterial balance with either inulin or rifaximin.

      The reactions (inflammatory, histamine, “yeasty”) they were observing were primarily due to the overgrowth of colonic bacteria and not to the specific nutrients themselves.

    Instead of using fish oil, how do you feel about hemp oil which is supposed to contain a balance amount of omega-3, six and nine.?

    • Author
      Patrick Nemechek, D.O. 3 years ago

      It will not work. While hemp oil contains a lot of omega-3 fatty acids, it is predominantly ALA and does not penetrate the brain much.

      Fish oil contains much more DHA and this is required for control in pro-inflammatory cytokines within the brains.
