Beware of Okinawa Diet scam!

I thought Okinawa Diet case has been rightfully forgotten a few years ago but a recent post on webmd Diet Debate board tries to revive it by linking this article , quote:

...Okinawa Centenarian Study. Okinawa, a chain of islands in southern Japan, has the highest concentration of centenarians. Uniformly these old folks have a vegetable-based, low-calorie, low-fat diet and exercise daily. They eat on average seven servings of vegetables and seven servings of grain per day, several servings of soy products, fish rich in omega-3 fatty acids, and little dairy or red meat.

My comment: I have come across Okinawa Study and the popular books by Willcox et al. a few years ago and came to a conclusion that it is totally bogus and a scam designed to sell their books, diet plans, supplements etc.

Here is what what do Okinawans probably eat, from WAPF web article :

And what do Okinawans eat? The main meat of the diet is pork, and not the lean cuts only. Okinawan cuisine, according to gerontologist Kazuhiko Taira, "is very healthy-and very, very greasy," in a 1996 article that appeared in Health Magazine.19 And the whole pig is eaten-everything from "tails to nails." Local menus offer boiled pigs feet, entrail soup and shredded ears. Pork is cooked in a mixture of soy sauce, ginger, kelp and small amounts of sugar, then sliced and chopped up for stir fry dishes. Okinawans eat about 100 grams of meat per day-compared to 70 in Japan and just over 20 in China-and at least an equal amount of fish, for a total of about 200 grams per day, compared to 280 grams per person per day of meat and fish in America. Lard-not vegetable oil-is used in cooking. Okinawans also eat plenty of fibrous root crops such as taro and sweet potatoes. They consume rice and noodles, but not as the main component of the diet. They eat a variety of vegetables such as carrots, white radish, cabbage and greens, both fresh and pickled. Bland tofu is part of the diet, consumed in traditional ways, but on the whole Okinawan cuisine is spicy. Pork dishes are flavored with a mixture of ginger and brown sugar, with chili oil and with "the wicked bite of bitter melon."

I also found my old post containing some information from Barry Groves (private communication), see what he had to say:

Okinawa (by Heretic on Aug-08-06, webmd)

I am trying to get hold of some papers on the subject. So far I found, surprisingly (or may be not...) that there is just as much confusion about it and contradictions in the literature, as about infamous "The China Study"(*). When I get the article text I will post some quotations. It will require a trip to the local uni library and paying some $$$. Let me quote after Barry Groves (private communication), the following citation:

In 1992 scientists at the Department of Community Health, Tokyo Metropolitan Institute of Gerontology, Japan published a paper which examined the relationship of nutritional status to further life expectancy and health status in the Japanese elderly[1]. It was based on three epidemiological studies. In the first, nutrient intakes in ninety-four Japanese centenarians investigated between 1972 and 1973 showed a higher proportion of animal protein to total proteins than in contemporary average Japanese. The second demonstrated that high intakes of milk and fats and oils had favourable effects on ten-year survivorship in 422 urban residents aged sixty-nine to seventy-one. The survivors revealed a longitudinal increase in intakes of animal foods such as eggs, milk, fish and meat over the ten years. In the third study, nutrient intakes were compared between a sample from Okinawa Prefecture where life expectancies at birth and sixty-five were the longest in Japan, and a sample from Akita Prefecture where the life expectancies were much shorter. It found that the proportion of energy from proteins and fats were significantly higher in the former than in the latter.

Update 9-Nov-2009

Description of Okinawa food:


Animal Foods, Seafoods, Fat and Okinawa Cuisine
Traditional foods of Okinawa are extremely varied, remarkably nutrient-dense as are all traditional foods and strictly moderated with the philosophy of hara hachi bu. While the diet of Okinawa is, indeed, plant-based it is most certainly not “low fat” as has been posited by some writer-researchers about the native foods of Okinawa. Indeed, all those stirfries of bittermelon and fresh vegetables found in Okinawan bowls are fried in lard and seasoned with sesame oil. I remember fondly that a slab of salt pork graced every bowl of udon I slurped up while living on the island. Pig fat is not, as you can imagine, a low-fat food yet the Okinawans are fond of it. Much of the fat consumed is pastured as pigs are commonly raised at home in the gardens of Okinawan homes. Pork and lard, like avocado and olive oil, are a remarkably good source of monounsaturated fatty acid and, if that pig roots around on sunny days, it is also a remarkably source of vitamin D.
The diet of Okinawa also includes considerably more animal products and meat – usually in the form of pork – than that of the mainland Japanese or even the Chinese. Goat and chicken play a lesser, but still important, role in Okinawan cuisine. Okinawans average about 100 grams or one modest portion of meat per person per day. Animal foods are important on Okinawa and, like all food, play a role in the population’s general health, well-being and longevity.
Fish plays an important role in the cooking of Okinawa as well. Seafoods eaten are various and numerous – with Okinawans averaging about 200 grams of fish per day.

 Pork is a very important ingredient, and every part of the pig is used, from pig's feet and pig's ears to pork tripe. Other ingredients include local seafood and native tropical vegetables and fruits.

Abstract quote:

The present paper examines the relationship of nutritional status to further life expectancy and health status in the Japanese elderly based on 3 epidemiological studies. 1. Nutrient intakes in 94 Japanese centenarians investigated between 1972 and 1973 showed a higher proportion of animal protein to total proteins than in contemporary average Japanese. 2. High intakes of milk and fats and oils had favorable effects on 10-year (1976-1986) survivorship in 422 urban residents aged 69-71. The survivors revealed a longitudinal increase in intakes of animal foods such as eggs, milk, fish and meat over the 10 years. 3. Nutrient intakes were compared, based on 24-hour dietary records, between a sample from Okinawa Prefecture where life expectancies at birth and 65 were the longest in Japan, and a sample from Akita Prefecture where the life expectancies were much shorter. Intakes of Ca, Fe, vitamins A, B1, B2, C, and the proportion of energy from proteins and fats were significantly higher in the former than in the latter. Intakes of carbohydrates and NaCl were lower.

More quotes from Shibata's paper:


The food intake pattern in Okinawa has been different from that in other regions  of  Japan.  The people  there  have  never  been  influenced  by Buddhism. Hence, there has been no taboo regarding eating habits. Eating meat was not  stygmatised, and consumption of pork and goat was historically high.  It was exceptional among Japanese food consumption.
The intake of meat was higher in  Okinawa... On the other hand, the intake of fish was lower... Intake of NaCl was lower... Deep colored vegetables were taken more in Okinawa... These characteristics of dietary status are thought to be among the crucial factors  which convey longevity and good health to the elderly in Okinawa Prefecture. ....

and the "kicker":

Unexpectedly, we  did not find any vegetarians among the centenarians.

Yes. It is a complete stupid hoax. The trad'l elderly Okinawans 70s 80s 90s 100 have HDLs in the 60s.

There is NO WAY IN HECK to get HDLs in the 60s without POUNDING dietary saturated fats.

No amount of exercise (come on they are 70s 80s 90s -- no one is running marathons).
No amount sake, alcohol.
No amount of fiber.
No amount of vegetables.

They eat a relatively high saturated fat diet.

Stan. Okinawa is quite close to Taiwan and the pork dishes you describe certainly sound familiar to me here. A lot of the pork dishes in Taiwan are of Japanese origin such as Don-katsu which is pork steak deep fried in lard. I've mentioned before that we certainly don't eat rice, as much as some of the high carb proponents would have you believe.

Stan Bleszynski said...

It has to be a hoax! The same applies to any high fat study that resulted in low HDL and high TG - these are obvious signs of data cooking.

From my few short visits to Asia, I was always able to find easily some high fat snacks everywhere, unlike in Europe or in the US. The only country where I could not find fat snacks easily and inexpensively was Ireland. I believe they are experiencing a heart disease epidemics at the moment.


Thanks for that video link, this is amazing that a vegan for 25 years was able to overcome his pre-conceived notion and just told the truth! He is a true scientist!

Hi Stan. And it also looks like Okinawa is longer a place for longevity, because of increased "healthy" vegetable oil consumption. Here is japanese paper, I could only read the summary: "nimal food intakes and lipid nutrition in Okinawa prefecture" - http://www.jstage.jst.go.jp/article/jln/16/1/16_39/_article

Stan Bleszynski said...

Hi O Primitivo,

"In our dietary survey of the main Okinawa island conducted in 1997, the fat-energy ratio in the diet of male subjects 40-59 years was over 32%, which was considered to be due to the use of large amounts of vegetable oil for preparing stir-fried dishes (Champuru) and deep-fried dishes. The EPA(%) of erythrocyte membrane phospholipids was lower in young women about 20 years old of Okinawa as compared with that in their counterparts in the Kanto region, because of the low level of intake of fishes and shellfishes by the Okinawan women. Recently, the life expectancy for men in Okinawa Prefecture fell sharply to 26th among the 47 prefectures of Japan, perhaps attributable to the upward trend of the mortality rate from ischemic heart disease and the cerebrovascular disease."

Low fat believers will undoubtedly be claiming that it is the pork not veg oil, or both responsible for the deterioration. Many vegetarians believe that in the mythical past, some long lived people ate nothing but low fat vegetables and fruit. What is interesting is that some of them like Dr. Fuhrman (not so long ago a vocal advocate of veganism) are now claiming that such diets cause arrhythmia, neurological problems among elderly etc, thus urge taking supplements and/or advise adding some meat, fish or nuts.

By "damn research", you must be referring to "China Study" book, aren't you?

Janknitz said...

I know this is an old post, but McDougall is at it again, touting the "starch-based" Okinawan diet as the key to longevity (see his June 2012 newsletter).

I find this amusing because I grew up on the island of Okinawa. My mother was a "locavore" before the world knew what locavores were, and loved exploring the local cuisine in places most Americans never dared, plus we had a maid (I know, but all the American's did in the 60's) who often cooked her traditional dishes for us.

First, I never saw a purple sweet potato in my life until 30 years after I left Okinawa--they were simply not common on the island during my time there. I suspect that when the Okinawans were rendered desparately poor and starving at the hands of the Japanese in the early half of the 20th century, they might have used sweet potatoes as a subsistance diet, but they put that diet far behind as soon as they could.

Perhaps this period of near starvation has more to do with the long lives (as in studies showing that calorie restriction prolongs life) than the starch from the potatoes. I remember being told by one of our Okinawan friends that they were so poor prior to and during WWII that it was impossible to replace broken pair of rubber zoris (flip flops) which cost all of $0.20 in 1965.

They did eat starch regularly, in the form of rice just like the customary Japanese diet, but also PLENTY of meat, fish, and vegetables, and no stinting on fat. I would hardly call it a "starch-based diet".

I think there are many factors that can alter health rather than age, but one thing i know from great aunts & uncles and their friends is that from traditional islamic diet, one should eat 1/3 full of their stomach, 1/3 of water & 1/3 of air.
So in essence eat what you want within reason but dont eat too much!
Happy living!

Stan Bleszynski said...


There is something in it, especially about the idea of eating only once a day (for example only after sunset).

Making very long breaks in between the meals does seem to allow the body to switch to a vital ketogenic cycle during the long breaks, even on a high carbohydrate diet.

Stan Bleszynski said...

Re: Janknitz description of Okinawa's diet

I have seen many reports corroborating your experience: high in fish, high in pork and high in green vegetables. It reminds me of Korean cuisine (except beef not pork).

I have been discussing this phenomenon (of vegan promoters' misinformation) with meany people and I still cannot understand this fully: why exactly are so many vegans willing to repeat that lie without bothering to check the facts?


Anonymous said...

This is very misleading because the diet of Okinawa changed dramatically in the 60s and 70s. Consumption of meat and fat exploded, and by the mid 70s, life expectancy in Okinawa fell in relationship to mainland Japan:


The traditional Okinawan diet was very plant-based, predominantly vegetables and grains. You can see a detailed breakdown on page 71 of The Okinawa Program.

I have access to the full Shibata et al paper. The authors shoot themselves in the foot later by pointing out that none of the correlations were statistically significant.

Stan Bleszynski said...


If you have an access to the full Shibata's paper "Nutrition for the Japanese elderly.", could you email it to me to stanbleszynski_hotmail C O M .


I have a note somewhere about a study of Okinawan diet in the 50-ties. Will try to dig it out.

Shibata's study abstract says:

1. Nutrient intakes in 94 Japanese centenarians investigated between 1972 and 1973 showed a higher proportion of animal protein to total proteins than in contemporary average Japanese. 2. High intakes of milk and fats and oils had favorable effects on 10-year (1976-1986) survivorship in 422 urban residents aged 69-71.

It is only theoretically possible that they have suddenly changed their diet between 1900 and 1970-ties but it is probably very unlikely for the elderly. People in their seventies do not generally switch their diets.

Regarding your link to "The Effects of Post-War Dietary Change on Longevity and Health in Okinawa", I consider Willcox brothers to be somewhat untrustworthy due to their popular diet/health book "Okinawa Program..." that predates that paper. There seems to be a conflict of interest here.

Anonymous said...

Are you still after this?



Stan Bleszynski said...

Thanks Anonymous for the pdf!

Fascinating data, it seems to completely undermine Willcox book thesis!

Not only did Okinawan centanarians consume more proteins and fat, they also consumed more animal protein and more animal fat! The centenarians' total cholesterol was higher and HDL much higher!


The food intake pattern in Okinawa has been different from that in other regions of Japan. The people there have never been influenced by Buddhism. Hence, there has been no taboo regarding eating habits. Eating meat was not stigmatised, and consumption of pork and goat was historically high. It was exceptional among Japanese food consumption.

The intake of meat was higher in Okinawa... On the other hand, the intake of fish was lower... Intake of NaCl was lower... Deep colored vegetables were taken more in Okinawa...
These characteristics of dietary status are thought to be among the crucial factors which convey longevity and good health to the elderly in Okinawa Prefecture.

My mother is s korean and growing up rarely had meat. When they had meat they would consume the whole thing. Pork usually. I am guessing other asian countries experienced the same. She eats meat daily now in the us.

Hello Stan,

I'm very interested in the topics of longevity and diet. While reading a lot of articles about the diet in Okinawa and came across your post here: http://stan-heretic.blogspot.com/2009/10/beware-of-okinawa-diet-scam.html

I've read the Willcox brothers' published papers and okicent.org, and I'm wondering how you came to the conclusion that they or their books are a scam?

Moreover, what have you found to be the optimal diet for yourself?


Stan Bleszynski said...

Hi Rick,

I came to this conclusion based on the disconnection between what Willcoxes wrote about their "Okinawa" diet and what Okinawans really seem to eat (based on many sources, Japanese and American). I was myself quite surprised when I found out. The most notable discrepancy being the highest proportion of pig meat, pig fat and fish among all Japanese prefectures, based on Japanese publications covering not only the recent post 1970-ties but also earlier historical data. This is the fact that Willcoxes completely glossed over and were either unaware of due to perhaps their lack of knowledge and poor research done on their part (which I doubt) or perhaps it may have been an intentional omission?

In view of this I am inclined to conclude that Okinawan longevity is probably IMHO solely due to their diet that is the highest in animal fat and fish among Japanese and the lowest in starch. The recent fall in longevity stats is most likely due to unhealthy effect of Western commercial junk food high in wheat, sugar, polyunsaturated vegetable oils and hydrogenated fats, that has been widely available since the WWII.

I found that my optimal diet consists of 60-80% of fat, mostly animal (but I do not exclude vegetable fats in seeds and nuts, in smaller quantities) and the rest is protein (mostly meat, organ meat, fish, eggs and dairy), and carbs (mostly vegetables and fruit). I have been eating like that since 1999, it is 14 years to-date.

I do not exclude any food but I rarely eat processed packaged food and if I do I always "read" the food labels using Jeff Novick's innovative way:

"If it has a label don't buy it"

Fran said...

I totally agree. I was born in Okinawa and go back once in awhile, and I have never seen a day there without a piece of fatty pork belly.

When I first read that thing about Okinawan diet being "low fat", I was surprised and confused because I had never heard of an Okinawan cuisine that was particularly low in fat, except raw vegetables or fruits.

You are totally right that Okinawans love meat, and from almost any part. I was often fed this soup that has weird chunks of meat that looks wrinkly and thin and must be part of the inner organs like intestines or something.

On a diet like this, my great grandmother had passed away at about age 102 or 112(forgot which).

I was reading about the "high-fat low-carb" diet just before, and I started to wonder if that was similar to the diet of Okinawans, but I am still not sure since I just learned about it.

I think it's definitely worth researching, though.

Thank you for informing people that the "low-fat" bit of the Okinawan diet was totally fake.

Anonymous said...

Hi Stan,
I found you page very interesting. Here in Spain where I now live, our diet is very healthy with tons of veggies, fruit, extra virgin olive oil, grains, fish and some meat (pork).
As a kid in London my mother always used pigs lard to fry with. During the 80s it was considered a dreadful thing to do as it would give you heart attacks etc........but everything used to taste SO good.
What do you think? Can I use it to fry the few fried foods we have with it?

Cloud Tiger said...

Stan, your page is very interesting.. not least the amazing confirmation bias apparent. The Shibata study certainly does not show what you wish it did... and even it said "Therefore, it is considered that dietary pattern of
the centenarians was established in the post Second World War period,
following the drastic changes.". There is no reason to believe that the later higher protein and fat consumption in 1970 was the same in 1949, when they were in postwar starvation, or even 1939 or 1889 when these centenarians were 10 and setting the base for their future health and longevity.

In fact it is nearly universal across the world that impoverished agricultural populations eat low meat and when they get wealthier they drastically increase the meat consumption ... and usually evidently suffer for it.

I see no evidence of these "earlier" Japanese studies supporting your high pork intake thesis. Where are they?

The "science" of these papers is weak... they try and sound good but in reality there are so many likely confounding variables that are unaccounted for that conclusions on diet affecting health and longevity with these epidemiological studies are a bad joke... suffice to say that even if modern diets were not irrelevant to the Okinawan longevity hypothesis and if the Akitans did not eat much more white rice and less pigmented veg n fruit (which would of course account for their lesser vits n mins) maybe they just smoked more! or the soil was bad... or they had a bad culture... who knows? Not these researchers, that is for sure.

Your biased consideration "Regarding your link to "The Effects of Post-War Dietary Change on Longevity and Health in Okinawa", I consider Willcox brothers to be somewhat untrustworthy due to their popular diet/health book "Okinawa Program..." that predates that paper. There seems to be a conflict of interest here."
is no excuse to dismiss it. That is not how science works. That the Willcox brothers wrote a commercial massmarket book before their paper is of zero importance.

The idea that researchers are all real "impartial" "objective" "scientists" is just idealist fantastical propaganda by the research industry. Even science itself has show that researchers are often biased. Research is not free and is often for sale. The idea that writers for the public and writers of science papers should be separate for safety's sake is just bogus as industry, power politics and science have always worked together, ever since engineers worked on better canals, catapults and chariots. It is a bent world... and it does not help when people dismiss good research and draw wrong conclusions from bad research just to fit their carb-phobic agenda.

As a US Army Officer living in Okinawa during 1948-49 and again 1951 thru 1953 the natives diet was primarily rice, a root vegetable and what ever they could obtain from the ocean. It seems every village had Chickens in their homes as a prize possession. During this era few villagers possessed a pig until 1950 era when US Government program provided a ship load of swine to the distressed island. When-Typically only the influential natives received US swine gratuities. Then the native'd water supply was thought to be contaminated as was native foods. Most often when military members çonsumed native prepared foods they frequently endured or suffered Monta Zuma's Revenge. On occasion, US personnel acquired lingering ntestinal infections requiring extensive medical follow-up before they were allowed to depart the island.

Stan Bleszynski said...

Hi Cloud Tiger,

Sorry for my slow response. You chose to believe in Okinawa rice eaters while I chose to believe in Okinawa traditional fish and pork eaters. Not all studies are screwed, only medical and nutritional. If engineers and real scientists (i.e. physicists, chemist and biologists) practiced a similar bias and tried to bend facts to their beliefs as nutrition promoters do, then the rockets would blow up on launch or bridges and buildings would collapse.

Efficiency is measure of truth. If it works it is true. Does your diet work for you?

There is NO WAY IN HECK to get HDLs in the 60s without POUNDING dietary saturated fats.

Really? My HDL consistently tests over 70, and I am a vegetarian who eats a diet very low in saturated fats (though not necessarily low In other fats).

Nice hyperbolic generalization, though.

Stan Bleszynski said...

If you are young (especially a young woman) or if you belong to ~0.5% of the population who maintain high HDL, low TG and are immune against metabolic syndrome no matter what they eat - it's possible!

Good thing about this discussion hyperbolic or not, is, that if your HDL or health may happen to decline over time then you will know how to fix it.

Hi Stan Bleszynski,

Thanks for the post! In many of the areas where vegans are rampant, there are tons of health issues. As for the meat eaters, they are slimmer and happier than those depressed people chewing only vegetables. Maybe, a mix of meats and vegetables is okay, but meat is an essential part of a healthy diet.

I got sick of watching the insane vegans pollute the search engines with their propaganda. This was one of the first articles I read that helped me realise the dark truth about veganism. Thx :)

[Postscript: By the way...Tōkyō Prefecture has the lowest fertility rate in Japan, while the Okinawa Prefecture has the highest fertility rate in Japan. It is obvious what each of these prefectures eat...)

Stan Bleszynski said...

Hi TheScienceEnthusiast1130,

You are very welcome and thanks.

Indeed, animal fat, meat, eggs, fish, dairy, vegetables and occasionally some fruit and nuts (in this order) seem to be the most natural human nutrition. As for the fertility stats, it is probably more complicated. Studies tend to show a correlation between hunter-gatherer/nomadic type of lifestyle (including diet) and moderate (not very high) fertility. Such populations tended to be very stable, very healthy and tall. On the other hand, populations dominated by settled tillage farmers tended to experience uncontrollable population explosions alternated with periodic famines and die-offs, has short postures and were not as healthy and the nomads.

Best Regards,

Wow im floored by your research because I have seen loads on propanganda online that the okinawans eat a low fat diet and mainly vegetables. My parents have been to okinawan themselves and said nope they aren't vegetarians though.

This the reason why the ketogenic diet which is really similar high fat is gaining so much popularity and people have said the weight melts off.

I have tried it myself just for fun and felt so much better about that I continued. My lipid panel came back wonderful 2 months ago, first in my life with a HDL of 82mg/dL and TG of 44mg/dL. My LDL also came to 88mg/dL

Well, as for the *actual* diet those people who are now centennarians ate in their youth:
85% carbs, less than 1% meat.
Sure, now they eat lots of animal products and fat, and they pay the price.

The dietary trend in East Asia during the last century and continuing until today has been a higher fat and animal product intake, which correlates with a rise in degenerative disease:

Stan Bleszynski said...

Hi Hans,

Regarding your first link, the first two authors (B.J. Willcox, D.C. Willcox) are also the authors of the Okinawa Diet and Okinawa Plan series of books. They have a vested interest in promoting a theory about what Okinawan eat and how they live, that conforms to what they wrote in their books. I do not trust that! See the papers about Japan and Okinawa linked in my post and the comment section above , which tell an entirely opposite story contradicting most of what Willcoxes' have published.

Next link from your comment: "The nutrition transition in South Korea" makes a fascinating read. The main change according to the study is a significant increase in consumption of wheat and vegetable oils (but not protein!).

South Korean diet remains still high in carbohydrates, although less so than in the past (from 81% to 64% between 1940 and 1995). Almost the same intake of protein, and double the intake of fats - predominantly in form of the most problematic fat that is vegetable oil!

Unlike you, I suspect that the main health risk is not related to the source of protein, plant versus animal (I consider this to be irrelevant) but rather I think it is correlated with the two main factors that come consistently through many studies (just one of them is for example China study data published on the Oxford University web site). Those two factors are consumption of wheat, and consumption of polyunsaturated fats from vegetable oils.

Incidentally South Korea is probably one the most prominent success story in terms of economics and human development, since the GNP increased more than 17 times between 1962 and 1996, while the total mortality rate halved (based on GlobalEconomy website, over 1960-2014 period) and life expectancy increased from 53 (1960) to 81 years (present).

South Korean data does not also support a theory advocated by authors such as Wilcoxes, T.C. Campbell and others that increase in consumption of animal produce is supposed to correlate with the so-called civillisation diseases. A good example is this study: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2853609/

Quote: Figure 2 presents contributions to the total life expectancy increase (11.9 years for males and 10.4 years for females) between 1983 and 2005 by disease group. For males, 65% of the total increase resulted from reductions in cardiovascular disease (CVD; 3.6 years; 30%),...

Wow! - I normally respond to published papers and data only. I don't want to waste my time debating vegan propaganda blogs, but that web site is really something special. I am really
impressed! Worth looking at their dedication, money and efforts they spend.

Seven people are listed employed as their management team, probably salaried, with titles such as Executive Director, CTO, Program Director, Development Director, Social Media Director, Volunteer Director and Translation Project Manager.

This is supported by hundreds of donors through monthly payments. It is sad to see so much money thrown at such a vegan nonsense. However, I believe that not all is lost and one can perhaps benefit from watching their material - note carefully what they advise to eat, especially Dr. Greger, and do the opposite! 8-:)


Treebark said...

Hi Stan Bleszynski,

I have been studying the Okinawa aging for some time now.
Studying as in reading peer reviewed articles about the phenomenon and making up my own mind based on facts.

From what i've read so far on the subject, there was (was!) a longevity effect and a lower disease index compared to mainland Japan but it was registered first in 1949 and by the 70`s the effects were starting to inverse.

There is plenty of studies about this out there, real scientific studies and reports not some popularization studies where you can find "proof" for any diet you might fad into.

I was skeptical at first, i've taken into account both possibilities, that it might be true or it might be fake, i've read article of other researchers not just the Wilcox.

The truth is that the data out there does not support your claims.

Plus that when faced to provide data you confuse the past effect with actual effect and the past diet with actual diet.

And then you say stuff like "i chose to believe in this version".

That is the closest thing to not supporting evidence based science you can get.

Sorry if i sound harsh but next time when you criticize a study, read all the papers out there and try to stick to the scientific ones and don't mix your facts up.

This is a wonderful post. I'm going to be looking at more of your stuff.

I think you promote capitalism as something that is good. I think capitalism is banking, usury and monopoly... no free market. I also believe Marxism is terrible and is a controlled invention of the money power. People are fighting over Marxism and capitalism when they are likely both controlled by the money power, just like republican and democrat are both mostly controlled.

Jana Jani,

Military Substitution rules look bizzare and seems to be poorly written. Is it a joke? Are you serious about replacing grapefruit with baking soda? There are no references to science, medicine or nutritional studies. :D


Thank you,
I love capitalism, have been working in the private sector since 1988. Capitalism and free market it allows for best expression of human potential. Live and let live. Liberalism & capitalism are inseparable. In my experience, capitalism doesn't seem to work only for people who do not want to express any creative constructive skills, who want to be paid for position and status rather than work, or are more interested in preventing others from expressing their true potential. Regards,

I think it is because calories are less easy to obtain for a hunter (but nutrients very high in every food he hunts) so fertility is lower but health high, agriculture inverts that and you get a demographic explosion but with bad health

I think, having fewer children while practicing a mobile nomadic lifestyle centered around hunting and fishing, is a good survival and life-enhancing adaptation. I studied quite a bit about Slavic nomads of the Eastern Europe (Sarmatian/Amazon period), and they migrated twice a year (Summer spent in the game rich North Central Europe, Winter around the Aegeian Sea and South Black sea. Lived in horse-pulled wagons like Gypsies or travelling on horsebacks like Tatars/Mongols or Turks, so having children at an inapropriate time would have been dangerous. I found also that they were matriarchal and women decided when they are going to have children and how often (and with whom). The other factor is of course purely biological since the high animal fat diet slows down puberty period to above 14-16 for girls, and above 16 for boys so that helps too.

On the other hand, a subsistence on a high plant high carbohydrate diet is treated by the body (autonomous body control system) as the emergency situation under duress, so all bets are off and having more children rather than fewer, even though at a price of short lifetime, is again a survival strategy (although a desperate one).

@Stan Bleszynski

That's surreal. Eating a high plant high carb diet is the norm for humans. That's what humans have eaten in all of history unless they were in an environment that did not allow for it. Staying in ketosis perpetually is the emergency situation which happens during sttarvation. As soon as carbs are eaten in a meaningful quantity the body switches back to the normal mode of using glucose for energy. We know that the *only* human population that is known to have eaten a diet that *might* have kept them in ketosis are genetecially selected *not* to stay in ketosis but to make carbs from fat! And their health wasn't good at all...

I'd have to see evidence for all those claims, including their diet, and I'm sure it would be flimsy. In fact puberty in Japan used to happen much much later for girls and has been rising rapidly as Japanese eat less carbs and more fat.

Stan Bleszynski said...

Re: Japan

- the opposite is true. As Japanese and others have added more refined junk carbs to their diet, puberty age goes down. Prior to that, Japanese and Korean diets were high in fish, meat and vegetables, which you can still see in their restaurant menus. Asians do not put rice and other carbohydrate-rich, it is typically a side bowl, not the main portion. It's a matter of wealth too, poorer people may not have much choice and have to eat mostly rice. Poorer children go thru puberty early, world wide and high carbohydrate high sugar diet is the main reason.

Re: "ketosis and normal"

- All or most archaeological evidence points to a dramatic reduction in lifespan and increase in the rate of disease (and dental decay) the moment a population switched from hunter-fishing-nomadic lifestyle to settlements and crop-based agriculture. Google it, find it out for yourself. Demanding more evidence is like asking me to prove that the Earth is not flat.


Hans said...

Restaurant menus? Really? Why do you think no study ever looks at restaurant menues to determine a populations diet? One has to be desparate for confirmation of one's prejudices in order to even go there. The real data proves that carb consumption in East Asia has gone down, way down. There's no evidence for a significant rise in sugar intake.


I won't waste my time doing your work. In no way is it possible to procure data on paleolithic diets that matches the power of the data I'm presenting here. Try proving that any of them ate a keto diet.

By the way, the above study on China also shows a decrease in wheat consumption in the sadly narrower time window it covers.
