Doctor's Note

What seven risk factors? That was covered in more detail in my previous video: Preventing Alzheimer’s with Lifestyle Changes.

There’s been an explosion of research on the Mediterranean diet recently, with about 500 papers published in the last year alone. I’m going to be doing an in-depth series taking a deep dive. To date I’ve only done a few that dance around the periphery:

I do have a bunch on dietary factors in cognitive decline, though:

    Plant-based fats a causation? 2 avocados a day — 2 ounces of cashews — 10 macadamia un-roasted —maybe some coconut oil also. Could this daily intake increase the odds of Alzheimer’s as effectively (or at all?) as the animal based fats?

    • Jane’s Addiction

      Dr. Greger has a number of videos on coconut oil which can be searched for on the page. The bottom line, though, is that coconut oil is essentially 100% saturated fat and is therefore just as bad for you as the fat you get in animal products. You’d have to ask someone else (i.e., someone not me) about the other fat sources you mention.

      • JoAnn Downey Ivey

        Check on for the Omega 6:3 ratio in many nuts, seeds, avocado and of course oils. They are not great, so a little of those foods goes a long way. All oils are highly inflammatory to the endothelium of the arteries. Vogel’s brachial artery tests showed a 31% constriction after ingestion of olive oil as an example. Coconut oil has absolutely no Omega 3 or Vitamin E – it is 100% fat most of which is saturated.

    Alzheimers and second-hand ingestion of drugs? Vaping devices are not just being used for nicotine. These gaping-electronic-devices are being used to discreetly smoke crack, pot, meth, you name it. What are the implications of second-hand breathing in of these drugs, as far as alzheimers? Public transportation……the guy in the bathroom might be smoking crack (what you think is an electronic cigarette filled with nicotine, but it’s filled with crack.) The lady in the airplane bathroom using her electronic cigarette to smoke meth, and there’s no way to detect it, or even prevent it. Innocents breathing it in. Someone in the restaurant smoking what we think is an electronic cigarette, full of nicotine, but it is packed with speed and coke, and here we are assuming all is ok, the air is fine. Dementia, alzheimers….this could get scary in the days, years ahead. It already is. The guy in the doctor’s office bathroom smoking who knows what out of his electronic-device. Yes, it’s time to take back our air. Many addicts don’t fit the “profile” of what we often assume. Lawyers, judges, doctors, fortune 500 executives, priests, professors, etc., drug addiction does not discriminate. It can happen to anyone. And these devices are allowing these folks to now subject us to their second-hand exhales.

    • Arjan den Hollander.

      Make an appointment with a psychologist for an evaluation, it sounds like the pipe has hit you too hard and there is a budding psychosis going on in your brain. This kind of internal rhetoric is a dead giveaway. Leave it untreated and your mind might deteriorate to the point it becomes useless.

      • airhealth

        Disagreed. Do the research. The technology is fully available for hard-core addicts to now put illegal drugs in these electronic devices that were designed to be used for nicotine-inhalation purposes. The second-phase of this is that what was once a society of addicts having to discreetly and privately take their drugs, well, they can now do it out in public, at work, wherever, and there is no “smell” detection. This is no small issue, and I think it might just pertain to dementia and alz’s, as I could very easily see breathing in second-hand crack in the restaurant bathroom might be an issue.

    • I don’t know where you live, but in my locality, No Smoking areas also means No Vaping.

      • airhealth

        People smoke these in public bathrooms and there is no way to detect it or even know they are doing it. We are breathing it in.
        I see people discreetly doing this even out in the open in places where it is banned. All it takes is a few seconds to take a hit.
        Sure, they are banned on airplanes, but we go into the bathroom alone, and these second-hand vapors have no “smell”, yet their chemical residue lingers, breathed in by……kids, all of us.

    • amyjo

      well, if you are hanging out in public bathrooms all the time, then you’ve probably got bigger problems than a few isolated incidence of second hand crack smoke.

  • Dave

    What a depressing disease.

  • HemoDynamic, M.D.

    They may live longer, but most importantly, do they live with a higher quality of life? Just because living longer doesn’t mean better.

    I have had some Dementia patients stabilize and slow the progression but I haven’t seen any “miraculous recoveries” once the disease shows outward signs of manifestation. So prevention is key!

    • Jackie Thomas

      Prevention is key to all of it. (chronic disease).

    • GeorgeBMac

      I cannot think of any worse fate than living longer with (true) Alzheimer’s…. There are other forms of dementia (now also often called “Alzheimer’s”) that do not have the steady progression of true Alzheimer’s. True Alzheimer’s slowly robs a person of their humanity and eventually kills them, slowly… It is a horrible disease. Other dementias do not have those characteristics….

  • jerrylamos

    “The risk of getting Alzheimer’s was 3.3 times greater among people whose blood folic acid levels were in the lowest one-third range and 4.5 times greater when blood homocysteine levels were in the highest one-third.” Clarke Arch. Neurol. 55 (1998) Ref. 76 Chapter 10 of The China Study by Cornell nutritional biochemist T. Colin Campbell. Folate comes from foliage (deep green leafy vegetables) and homocysteine comes from animal-based foods. Study published whithin the last week 2 years with dementia people with high homocysteine levels taking synthetic folic acid pills did not help. Duh…. Amazing how many nutritional researchers don’t read in their field.

  • Laloofah

    Would someone in the know please clarify for me, are “Alzheimer’s” and “dementia” used interchangeably here? And am I correct in thinking that Alzheimer’s is but one form of dementia?

    It’s unfortunate that many (most?) people incorrectly equate “the Mediterranean Diet” with high intakes of fish, wine, cheese and olive oil rather than of vegetables, fruits, beans, nuts… And of course, a wide variety of countries, cultures and cuisines are “Mediterranean,” so which “diet” is THE Mediterranean one? I’m glad this video cites studies that help clarify that (as usual) it’s whole plant foods that are beneficial.

    • Merio

      You’re right… there are many kind of dementias and Alzheimer Disease is one of the most “famous”…

      While for me the true Meditarrean diet its really high in whole plant foods while animal foods are kept low, but i think it really depends on the location… populations next to sea tend to eat fish and probably not in moderation, but i’m not sure of this.

        • Merio

          Oh, yes we have a lot of locations… :-)

        • Laloofah

          Exactly. Which is why I have issues with the term (and (mis)interpretation of) “the Mediterranean diet.”

          • Merio

            i think you should study the books about the blue zones, or Ancel Keys works about diet.

            My thoughts about the “right” Mediterranea diet is probably a WFPB, but olive oil it’s use only as a condiment and one/two times per week there are serving of meat/fish.

            Stables are whole grains, legumes, veggies and fruits.

            I think that the BOMB diet could fit well for the purpose.

          • Laloofah

            My thoughts about the Med diet (and any diet) is the same as yours, Merio – WFPB! Thanks for your recommendations, but I’m good! :-) My husband and I have been ethical vegans for 14 years, and we came to it via a health issue, when I was diagnosed with Multiple Sclerosis 20 years ago this month. That’s when we started learning about health and nutrition and changing how we ate, and in 2007 I attended Dr. McDougall’s 10-Day Live-in Program. The more we learned, the more reasons we found to change our perspectives and habits, and our only regret is that we didn’t do it sooner. (As for the MS, I’m symptom-free and have been for many years, without drugs. So I take no convincing about the huge health benefits of a WFPB diet!)

            My mom has dementia (but not Alzheimer’s), as did her parents (the Italian side of the family!) She’s been doing much better since moving into Assisted Living last summer; living alone had her depressed, paranoid, disoriented, hallucinatory… it was bad. She’s suffering memory issues, but everything else is vastly improved, it’s like night and day. Now if only the place would feed them WFPB diet! :-)

          • Merio

            Probably you have much more information than me since you have beeing study the diet issue for > 14 years right ? XD

            Great that you succeed in beating the MS.

            Hope that your mom continue to improve :-)

            I’m italian.

          • Laloofah

            Actually, it’s been close to 20, since someone put me onto Roy Swank’s “The MS Diet” shortly after my MS diagnosis, and that’s what started the ball rolling for me. Grazie mille for your kind words and well-wishes for my mom and me! (I figured you were Italian, paisan. :-) (Mom’s name is Possenti, my grandfather was from near Pisa). Ciao, Merio, buona giornata!

          • Merio

            It is always a pleasure to meet on english’s blogs someone who can talk italian :-)

            I live near Milan and practically all my parents lived in Lombardy.

            Le auguro una buona serata !

          • Laloofah

            You give me more credit than I deserve, as I can only speak the few words and phrases of Italian my grandfather taught me, and can write far less. I didn’t have an opportunity to study it till college, and by then I had five years invested in studying Spanish. But I’d love to learn to speak it – it’s such a beautiful language! – and since learning another language helps stave off dementia, I think that sounds like a great idea for the New Year. :-)

            Even more than I want to learn Italian, I long to visit Italy someday!

          • Merio
          • Laloofah

            Bon giorno! And thanks for this! Not only will I learn to speak Italian, but will be able to do so with my mouth full (“mangia, mangia!”) AND be able to tell people I’m an MIT grad. Not bad! :-)

            I found four different “Learn to Speak Italian” courses on CDs at our local library, plus they participate in the free Mango Languages program. So between all that and Paola here, I should be fluent in no time – and dementia-free for life! :-)

          • Merio

            Perfetto !!


          • janet

            Sorry — what is WFPB diet?

          • schemer

            Whole Food Plant Based

          • janet


        • Darryl

          Essentlally the study used a 9 point scale, with points awarded for higher than median intake of 5 categories [fruits, vegetables, legumes, cereals, and fish], lower tnan median intake of [meat, dairy], and high MUFA:SFA ratios and moderate alcohol intake. Whole food plant based diets would automatically score at least a 7 (8 with moderate alcohol), and fall into the high adherance tertile (6-9) with the best outcomes.

      • Jackie Thomas

        I had been wondering about Omega-3´s. If they are so critical in our biochemical pathways, why are they so hard to come by? Oh, I know, flax and walnuts, but after a little reading, seems like in the biochemical conversion a lot gets lost (ALA into DHA, EPA). And how were the ¨hunter-gatherers¨ getting so much flax or walnuts, anyway. So…fish? I didn´t imagine much fish in the long ago history, until I watched a little youtube yest on the history of man. Just a glimpse, really, but they showed how almost all of the beginnings of mankind were around the sea. Fish was easy(ier) to harvest and eat. If someone can help with the dilemma, I´d appreciate it.
        I am now a WPFB person who eats 100g sardines every other day. I don´t like the mercury implication, but…

        • Merio

          Unfortunately even if i’m (also) a biochemist i’m not able to answer that question (it’s not my field).

          From my point of view, past population (hunter gatherers) never were “vegan”, maybe they ate very little animal food, but indeed some % of calories derived from animals/fish… probably even insects (that are ubiquitous and easy to “hunt”).

          But fish i think was indeed a great option for ours ancestors.

        • Adrien

          Here an interesting post from Jeff Novick :

          The rate of conversion of ALA to DHA is two time better when you are on a WFPB diet. Flax and walnuts are indeed great source of ALA and very healthy food in the same time. Flax for exemple should be consumed not solely for it’s omega 3 content. There is small amount of omega 3 in many food including beans and greens that contribute to your omega 3 intake. Flax and walnuts are just the most concentrated source. Our ancestors probably get more omega 3 from greens than from fish over long period of time.

          Here a quote from John Langdon of the departments
          of Biology and Anthropology of the University of Indianapolis : “[b]There is no evidence that human diets
          based on terrestrial food chains with traditional nursing
          practices fail to provide adequate levels of DHA or other n-3
          fatty acids.[/b] Consequently, the hypothesis that DHA has been a
          limiting resource in human brain evolution must be considered to
          be unsupported.”

          More on this great paper from McDougall :

          I think you should focus on what is the best that you can do today for your health rather than to think how ancesters did in the past.. Today we can have the best food everyday, not so in the distant past.. and if you still want – like me – a source of DHA without mercury, PCBs and so on, there is good algae-based supplement on the market.

          • Jackie Thomas

            Chris Kesser

            However, research clearly indicates that the conversion of ALA to EPA
            and DHA is extremely limited. Less than 5% of ALA gets converted to
            EPA, and less than 0.5% (one-half of one percent) of ALA is converted to

            A common misconception, especially amongst vegetarians and vegans, is
            that our need for EPA and DHA can be met by consuming flax oil and
            other plant sources of ALA. But the conversion numbers above clearly
            indicate that this isn’t the case.

            Studies have shown that ALA supplements (like flax oil) are unable to
            raise plasma DHA levels in vegans, despite low DHA levels at baseline.
            (ref) So unless they are supplementing with an algae-derived source of
            DHA, it is likely that most vegetarians and vegans are deficient.

            FROM WHFOOD in summary If you choose to avoid all animal foods (including seafoods), we
            recommend a discussion with your healthcare practitioner to determine
            possible supplementation with omega-3s.

          • Jackie Thomas

            I know there are omega 3´s in veggies in addition to the walnuts, flax, but it´scant. Again, I ask, if omega-3´s are so critical, where did they come from? We could never have eaten enough flax seed, walnuts, etc. way, way back yonder to supply our bodily requirements. I´m not even sure there was such a thing as walnuts, but there was fish. Just my take.

          • Adrien

            Omega 3 comes from plants always, even in the sea. Fish cannot create omega 3, just like us. We, just like the fish, are just able to elongate the molecule. Only plants can synthesized omega 3.

          • Adrien

            Read the two articles I pointed out, there is scientifique study backing
            what I’m saying. The post from Jeff Novick and the one from McDougall.
            From start to finish. You’ll find anwser to all your question.

          • Thea

            Adrien: Great post! Thanks for this specific information.

        • Thea

          Jackie: As Jeff Novick says: To know whether or not you can get enough omega-3s from your food, you have to know: a) how much omega 3s you need, and b) how much you are getting from your food. Then proceeded to answer both questions, including showing a great chart with how much omega 3s you can get from various foods, including greens like broccoli. It turns out, if you eat enough servings of whole plant foods (say 9 a day), all those servings of veggies etc, and skip the meat/fish, diary, eggs and other junk food, you end up getting enough omega 3s. No fish is needed at all. Seems like our ancestors would have easily met their omega 3s that way.

          With the better conversion levels that true vegans enjoy, some added flaxseed gives plenty of insurance on top of a true WFPB diet.

          You can see all of the charts and learn more in Jeff’s talk: From Oil to Nuts. I haven’t had a chance to look at Adrien’s links yet, but I’m guessing that information will be helpful too.

        • JoAnn Downey Ivey

          It’s interesting that vegans who eat absolutely no animal products are much more efficient at conversion of linolenic acid.

      • Laloofah

        Thanks, Merio – I knew one of them was an “umbrella” term, and thought it was most likely “dementia,” but they do seem to be used interchangeably and I still wonder if that’s happening in this video.

        • Merio

          I think that clinicians could be too used to this particular term and simply use it without thinking that the average man is ignorant to the fact that dementias are a spectrum of disorders:

          Any neurologist out there could say if i’m wrong ?

    • bob

      “Not all researchers agree that there is any such thing as normal memory
      loss, however. A study conducted by researchers from the Rush University
      Medical Center in Chicago and published in the journal Neurology
      in 2010 followed 350 Catholic priests, nuns and brothers for an average
      of 13 years and then autopsied them after death. The researchers found
      signs of brain damage in all participants who had exhibited signs of
      memory loss. Not all the damage, however, was due to Alzheimer’s

      I have one word….PREVENTION.

      • Laloofah

        I agree that prevention is where the action is, and plant foods are where the prevention is! :-)

        • GeorgeBMac

          … And exercise. The brain needs a huge amount of nutrients and oxygen and aerobic exercise gets it there and strengthens the cardio vascular system to keep it coming. And resistance training builds the muscle that helps keep excess sugars under control.

          • Laloofah

            Yes (and nice timing, we just returned from a good brisk walk, yay!) :-) And I’ve read in several articles that learning challenging new skills, like a foreign language, quilting, chess… all good for staving off dementia too! (Plus they keep life interesting!)

          • GeorgeBMac

            Yes! That great!
            and “brisk” is key… While a stroll is better than nothing, it is important to get the heart rate up – even to sweat a little – at least 30 minutes every day.

            As one person put it: “Only eat on those days that you exercise!”

            To often it splits into the nutrition camp vs the exercise camp. We need BOTH!

          • Laloofah

            I couldn’t stroll if I tried. :-) I’ve always been a fast walker, and it’s my favorite form of exercise (bike riding is 2nd.) Trouble is living in northern WY, where the weather and the walking paths are so often treacherous! And I don’t have a treadmill. So I miss some days at this time of year… guess I can’t eat on those days now. ;-)

            I thought you might enjoy this PCRM article I just read yesterday – it has to do mainly with cancer prevention and survival, but as you know it applies to plenty of health issues: “The Roles of Exercise and Stress Management”.

          • GeorgeBMac

            EXCELLENT article! Thank You for sharing that!

            As I was reading it I was struck by how much it sounded like Dean Ornish talking about the prevention and reversal of heart disease.

            Isn’t it amazing (not to mention convenient!) how the things that reverse or prevent cancer also do the same for heart disease as well as dementia.

          • Laloofah

            I’m glad you enjoyed it too, and you’re most welcome!

            Yes, it’s very handy how the same relatively simple and readily available preventions & remedies are effective against so many seemingly complex diseases, and wonder why so many insist on making it seem so complicated and unattainable.

            By the way, inspired by the article I sent you and your replies to me, my husband and I have decided to treat ourselves to an exercise bike (would prefer a treadmill, but lack the room) so we can get our aerobic exercise no matter the weather! And Merio has inspired me to grab some “learn Italian” CDs from our local library. So thanks to the two of you (and Dr. Greger), I should manage to hold on to my wits for a couple more decades, at least! :-)

            Happy Thanksgiving!

          • GeorgeBMac

            Best of luck with the exercise bike! That’s great news and a good decision!
            One suggestion to consider is getting a regular bike and mounting it on a trainer for the winter. I don’t know how the cost compares – but that would provide you with year round cycling (assuming that you have a safe place to cycle outside).

            Happy Thanksgiving to you!

          • Laloofah

            We’d actually considered that idea (mounting our bikes on a trainer) last year, but rejected it for various reasons I won’t bore you with. :-) After doing some further research this afternoon, we’ve decided on an elliptical (better cardio than a bike, lower impact than a treadmill), and have been researching the reviews and consumer reports ever since. Might even brave the madding Black Friday crowds (urgh) to check one out at our local Sears tomorrow.

            We have a wonderful walking/bike path system here (we think it’s the best thing about our town), and I sure do miss our almost-daily bike rides and long (5+ mile) walks when winter arrives!

            Thanks again for your help, advice, and support – it’s much appreciated! :-)

          • GeorgeBMac

            Best of luck with the elliptical! Good Choice!
            Last winter I started to move from cycling to running on my treadmill. But a torn cartilage in my hip put a stop to running. Unfortunately, my slave driver (oops! I mean my cardiologist) wanted me to start HIIT (High Intensity Interval Training) on the treadmill — which I couldn’t do because I couldn’t run.
            But, after joining a gym, I discovered the elliptical and love it! That’s partly because, like a cycle, it doesn’t bother my hip and also because it is all manual, I have complete control over the intensity: I added the cardiologist’s suggested heart rate intervals into DigiFit on my IPhone and then simply connect the dots with my heart rate — when the next 4 minute block calls for a higher heart rate I go faster, and when the next block calls for a moderate heart rate, I slow down. Love it! I hope you get the same benefit I have been getting from it! I showed the results to my cardiologist when I saw him a couple weeks ago and he was VERY pleased!

          • Laloofah

            This is great to hear! Most importantly that your progress has so pleased your whip-cracking cardiologist (lol), but also that you really enjoy using it. I was particularly happy to hear it doesn’t hurt your hip, since I have an old hip injury/trigger points that I sure don’t want to aggravate. Our neighbors have invited us over to check their elliptical out today, which we’ll do – she said they both experience numbness in their feet when using it, which is an issue we’ve been reading about. Apparently the higher-end ellipticals have successfully addressed it with adjustable foot pedals, and since gyms have professional-grade ellipticals (and since you love it and voiced no complaints), I assume you haven’t experienced that problem.

            Thanks so much for sharing your experience – and your enthusiasm! :-)

          • janet

            Ha! Ha! — Yeah – and for ‘insurance’ only eat vegan on those days that we exercise. Imagine the reduced health-care. Just wondering if ‘vegans and exercisers’ could get tax reduction as they are not utlizing hospital services and are ‘taking care of their own health’ – and not taxing any of the systems – that’s – not supporting ‘Big Pharma’ (taking any drugs – because they’re so healthy) — not supporting Big Med (we don’t go to the doctor) — not supporting BIG AGRO (the cruelty/terror/killing machine that slaughters millions of helpless animals daily and billions annually. Vegans save 100 animals/year. Does this sound like it’s good for the environment (saving on land devastation – saving water (thousands more gallons of water to make one pound of dead flesh compared to water needed to grow broccoli). When cows aren’t getting raped and babies not being kidnapped from their mother at birth – and the rainforest is not being ripped down at 1 acre/second to put cows there so people can have their steak – does this sound like a win for the planet? If eating vegan gives us a clean bill of health and we are not a burden on the health care system – does this sound like veganism is a winning solution – not to even mention the original topic introduced by Dr. Greger — alzheimer prevention. Go

    • GeorgeBMac

      Yes, Alzheimer’s is technically a unique disease characterized by plaques, tangles and a predictable progression starting with memory loss and ending with death (while the interim is too horrible to speak of).
      Unfortunately, the Alzheimer’s Association has begun to blur the boundaries and definitions between Alzheimer’s and other types of dementias. That may help their funding and it may help validate their claim that 80% of dementias are of the Alzheimer’s type. But it really hurts both understanding and scientific research: if you don’t know what it is you are researching, you will not come up with any reliable answers: Researching dementia/Alzheimer’s is like researching ‘diseases of the chest’ — it could be any number of actual, unrelated diseases

      • Laloofah

        Thank you! That was very helpful.

  • HemoDynamic, M.D.

    BTW, Keep the, “Until Now” coming! I love hearing that statement but I am not sure why. Maybe becasue I know I am about to get a good dose of current research.
    I think it has become your signature statement.

  • Ann

    Thank you so much for posting!!! I hope you do more on this subject. Everybody on my mom’s side of the family got some type of dementia (mainly Alzheimer’s) in their old age, and it is so encouraging to see that it can be avoided. I hope this vegan diet/jogging thing does the trick, and thank you so much Dr. Greger, for all that you do. If anyone can save our country from this mess it is in I believe you will be at the forefront. I’m a Democrat, but unfortunately Obamacare is a total joke and will do nothing to help healthcare (except more than double our premiums!!! And I speak from experience), and will drastically hurt the Democrat party unless Hillary can put some sense back into our leadership. Our health and our nation can only be saved through sensible lifestyle changes, not through taking more money from peoples’ wallets and slamming it into more “sick care.” A vegan nutritarian diet and our jogging shoes are our only hope.

      Am I missing something about the whole obamacare thing? When I´m shopping for health ins., (supplemental, actually), they can´t ask me anymore about my ¨past history¨, so my prior cancer isn´t on their radar anymore. No questions about past health issues. Wasn´t the elimination of pre-existing health issues done away with when Obamacare became law? If that´s a case, it sure as hell isn´t a joke for me! Oh, yes, here it is.
      I don´t want to get political here on this site, but…

    Dr. Gregor has shown that a plant based diet can make you biologically 14 years younger than any other diet. Perhaps this is customizable to you as a person, in terms of fibonachi based on how adherent you are. That you could be 1,1,2,3,5,8,13, or even 21 years younger depending on how much you participate in the healthy foods he suggests. Knowing that the best of these foods includes brocalli, garlic, beets, lemons, apples, cranberries, alma, rosehips, blackberries, strawberries, walnuts, pecans, peanuts, heavy bean consumption, rosemary, turmeric with pepper, cloves, ginger, hibiscus tea, dandelion tea, and chamomile tea, the more of them you consume the healthier you can be. Perhaps heavy doses of these foods can help beat aging. Since Alzheimers isn’t exactly genetic, maybe diet plays a huge role. It is hard to assume Alzheimers is genetic since it strikes the elderly and they seem to know that they are happy. Perhaps it is because they are missing children or grandchildren from their spirit and lack the ancestors to make up for them. Perhaps they are struggling to see something they are missing. Some people turn to medications to see more of their family. I think a major cause of diabetes and obesity are the most profitable medicines in the country, Zypreza and Haldol and antidepressants which make people really gain weight and can raise their blood sugar. Maybe they can damage the brain too when used wrong or over used to treat genius ideas, not mental illness. Whole grains can prevent stroke and dementia, and berries can make your brain two years younger. Grapes and cherries are also effective at battling the aging of the brain. Diet can play a role in slowing the shrinking of the frontal lobe, and so can language and memory games like Legos and gardening. People with Alzheimers can perform the most complicated tasks that are stored in different parts of the brain. Nuts, beans, dark chocolate, matcha tea, whole grains, fresh fruit and vegetables might be our most effective treatment for Alzheimers, it already seems to be for Parkinsons and some other neuroligcal disorders.

      We really have no idea have no idea what Alzheimer’s is – we are only knows it symptoms. So prevention can only be determined by trial and error: “We tried ‘this’ and it usually worked”.

      But many, I believe most, dementias are brought on by vascular insufficincies – the brain does not receive adequate nutrients and oxygen. We DO know how to prevent that: Diet & exercise!

    This is a good article and good studies. But it is important to first define what one is talking about when speaking of Alzheimer’s.
    Just a few years ago Alzheimer’s was defined as a predictably progressive deterioration of the brain characterized by plaques and tangles — and it was specifically differentiated from other forms of dementia. But, more recently, those boundaries are being greyed to where Alzheimers and dementia have become synonymous. Are we speaking of plaques and tangles or dementias caused by vascular deficiencies? Mixing the two is like speaking of “diseases of the chest” — is it an MI, CHF, COPD, pneumonia? It makes a difference!

    we all lose its alright

    Forty percent of Americas over 85 will get Alzheimer’s. Dr. Greger recommends saffron and tumeric with pepper (based on a very small case study). for Alzheimer’s, maybe aroma therapy with lavender and citrus would help. Perhaps if their minds need more energy to hold onto all the memories they could be feed more B12 or Phosphorous or even plant protein. The brain is made up mostly of fat, and the body always digests its own fat in time. Telling the difference between different fats has a lot to do with metabolism and Phosphorous and Adenosine (the stuff of ATP, the food source of the body) could keep us going. Spinach must really help the mind. Does copper help control the brain?

    I have recently heard some positive things about Silica and Alzheimer’s. Could someone from NutritionFacts comment on that?

      the low fat diet group was 37 per cent fat , that is a low fat???

    just use olive oil or peanut oil instead if you really need your oil fix.
