Dr. Michael Eades: Paleopathology and the Origins of the Paleo Diet
Вставка
- Опубліковано 29 лис 2019
- “Blood-vessel disease was common (among the ancient Egyptians), contrary to assumptions that it arises from urban stress and a modern high-fat diet,” Dr. Michael Eades, MD, reads aloud to the audience at the CrossFit Health Conference on Aug. 1, 2018. Eades is a well-known physician and author of several books about the science behind low-carb diets, but this quote from Arno Karlen’s book Napoleon’s Glands brought to mind knowledge from a previous career path, when he was a college student interested in Egyptology.
Eades had researched the dynastic Egyptians’ lifestyle and knew they had eaten a wheat-based diet. The statement he read in Karlen’s book, he says, “electrified” him. He recalls waiting in anticipation for the library to open the next morning so he could perform additional research on the ancient Egyptian diet and its potential relation to cardiovascular disease (CVD). In this presentation, Eades shares some of the outcomes of that research, taking his audience “on a journey through the anthropological literature and what that means in terms of ‘off the carbs.’”
“So if you look at all the data out there,” Eades concludes, “you look at the metabolic constraints, the Kleiber line, the expensive tissue hypothesis, you look at the stable isotope data, you look at the hunter-versus-farmer data, you look at the ancient Egyptian data, you look at the modern RCTs, and it’s pretty clear that ‘off the carbs’ is the way to be.”

I stand before you as a guy who is no longer a type 2 diabetic and healthy as ever. 2 months on a keto/fasting regiment and blood sugar is perfectly normal. 30lbs lighter and various other illnesses gone.
It's great that you have reduced your blood sugar level. The reason why your glucose is down is because your intake is down - whilst keto can drop your weight and start to normalise your insulin and glucose levels, it is not a cure. Some proponents refer to it as a reversal. However, as Dr Sarah Hallberg, Medical Director of Virta Health (Keto T2D Diet Plans) admitted on camera at a conference, it is not a cure and it isn't even a state of remission. She stasted plainly that anyone following this regime would spike their blood glucose the moment that they eat carbohydrate.
The issue is that it's not addressed the cause, which is a build up of fat in the muscle cells, where it shouldn't be in average people. This stops the insulin from doing it's job, namely to get the glucose out of the blood and into your cells. The best non-jargon explanation of the cause and the solution I've ever seen is in this podcast. Cyrus Khambatta has a PhD in Nutritional Biochemistry, specialising in diabetes - he really knows his stuff!

Good luck and good health.
Amen. Me too. Genetic, long term insulin resistance, high seed oils, etc. It may break people. Then keto will remise it. And it maybe a forever thing. Then again. It was never good in the beginning so it was needed the whole time.
@@stephensaberi5822 and that's from seed oils. And if a person is holding that that's for meeting too much added sugar without exercise.
I’ve been studying diet and physiology for about two years now and this Dr was absolutely way ahead on this topic.
Learned so much from this Man.
Thanks for all you and your wife are doing.
We appreciate you checking it out, Joe! Glad you enjoyed it!
You touched on one of the big reasons I chose to raise livestock: stability.
If a plant crop fails then we would starve for a year, or longer. But raising livestock my food source, and livelihood, is more resilient to weather events.
This was particularly pointed out back in the mid 1800’s when it was cold for three years causing massive crop failures.
Again in the 1990’s we got snow every month of the year. The native plants survived, largely, but my gardens and crops took a hard hit. On the other hand, our livestock were fine because their diet was the native forages. So meat that year was a larger part of our diet.
The animals can turn plants I can’t eat into high quality protein, lipids and minerals.
I raise livestock and plants, but gathering and hunting are my backup.
Very interesting details in your lecture. Thank you.
Thank you Dr. Eades for this outstanding presentation. Anyone who claims, after an honest appraisal of the evolutionary and anthropological literature that is cited in this presentation, that we are "meant" to eat mostly plants is just hellbent on distorting to the truth, so as to propound a vegan ethical and/or environmentalist agenda. Nearly everything about our physiology and dietary history points to the fact that the optimal diet is one that heavily favors carnivory.
It certainly is a very well structured presentation. Part of the evidence cited here (the isotope ratio work) appeared in the film "The Perfect Human Diet", which I watched some time ago. It is probably this line of enquiry which made me sit up and take notice. However, it would appear that the 15N: 14N ratio is not quite linear and straightforward as Dr Eades might have us believe. It turns out that there are a number of factors which influence that ratio. It was interesting to note how Dr. Eades explained the high 15N levels in our hunter gatherer predecessors - he said that to achieve these levels, they would have to have been eating the indigenous apex predators. The principle is that the lighter isotope is preferentially excreted in the urine and thus as one moves “up the food chain” then the ratio should increase. However, there are many potential confounding factors, such as water scarcity which alter the metabolic process to favour a concentration of 15N in the body, irrespective of what the animal eats. If we rely upon the isotopic data, we find that the gazelle eats more meat than the lion and the Pygmys eat more meat than the Jaguar. When this is combined with the known kill rate of even the best hunter gatherers (around 30%) it quickly becomes clear that it is perhaps unwise to use this data to promote the idea of Palaeolithic man eating mainly meat.
Following in the footsteps of Loren Cordain, he sites the Inuit as an example of excellent health on a fat heavy, meat based diet. In reality the science shows quite unequivocally that there is no “Inuit Paradox”. Whilst the modern day Eskimo has a shorter life expectancy than the average Canadian, many ascribe this to the gradual shift to a standard Western Diet and in many cases pronounced alcohol addiction. However, the examination of perfectly preserved Inuit, frozen between 1600yrs and 500yrs ago shows extensive atherosclerosis and calcification of the arteries and even the heart valves at the tender age of 45yrs old. There was also a deal of osteoporosis evident. (www.ncbi.nlm.nih.gov/pmc/articles/PMC325106/)
The results were consistent across several recovered bodies. Bear in mind that except for some berries available during the very short Arctic summer, they ate meat and fat exclusively, much of it raw and also drank the blood. The level of arterial damage speaks volumes.
For a detailed look at the isotope ratio issue and the more recent discovery of grain consumption amongst the earlyn homonids, I suggest taking a look at this presentation: ua-cam.com/video/FNIoKmMq6cs/v-deo.html
@@stephensaberi5822 That is interesting. I will have to look into this. I appreciate you bringing up a contrary point of view in such a well written fashion.
@@alphacause Thank you - you're most kind! I wish you good luck and good health whatever path you choose to follow.
Another brilliant doctor 😷
Great work! ❤
CF HQ - It would be great if you could upload the audio of these lectures to your podcast.
Sincerely - affiliate owner who doesn’t have time to watch an hour of YT
There is an option to listen to the audio on YT mobile app. I do this while commuting in my car.
Wished that Dr. Eades and Dr Mcdougal debated each other. That would have been electric.
Just ate a lamb chop and pork rinds. Some pineapple 🍍 for desert. 🙏✨️🏋
A definitive lecture.
hello everyone! have a great weekend!
Unfortunately the 44222 option to get the papers is no longer available.
Type 1 diabetic here, no longer suffering from insulin use. If you don't eat plants, and you are active, your blood sugar doesn't increase and you don't need insulin.
Go team humans! Btw...meat eating far less disruptive (if not neccessary) for the enviroment than agriculture. (And cue the hate 😆) if you grew up around cows, farms and the forest as i did...its obvious to see that farms tear down forrest, but i spent many a summer with cows walking around my swimming holes rivers and trails grazing throughout the summer. Plus...how much pesticides goes into the ground at a ranch vs a farm....answer is very very simple. Last....almost a quarter of the earth can super grass eating animals. Less than percent can grow plants...so how do we feed the world? Ok...sermon done
“If a modern heart doctor could give medical advice to the iceman Ötzi - the man who was preserved as a mummy after his murder about 5,300 years ago in the snowy Alps - it would be this: Stop eating so much fatty meat and consider taking medications that lower your blood pressure and cholesterol. [Or eat a WFPB diet!]
This advice is based on a new comprehensive look at the iceman mummy's cardiovascular health. A full-body computed tomography (CT) scan showed that Ötzi had three calcifications (hardened plaques) in his heart region, putting him at increased risk for a heart attack. “
See Livescience article, “Ötzi the Iceman Was a Heart Attack Waiting to Happen”
Otzi had wheat crackers in his pouch.
Otzi was a farmer migrating through paleo territory...hence the arrows.
What kind of a person would mention a book like that?
My problem is, where the hell do I get fresh meat? All the meat in grocery stores is all aged for weeks before they ever put it on the shelves. And unfortunately the government won't allow me to hunt often enough to keep myself fed. And butchers are too damn expensive.
Weeks old meat is infinitely better than bread and beer. Geeze
@@EthanE3 I've never had a beer and I never endorsed eating bread.
It's rushing of for me and I get organic ground beef at Aldi. They also have grass fed steak but it's not organic.
It's very interesting that Dr Eades says that it was "absolutely crazy" to say that the extensive arteriosclerosis found in the ancient Egyptians was due to the consumption of saturated fat. I assume then that he puts it down to their consumption of bread.... All the examinations were performed on mummies, since they are so well preserved. Perhaps the pertinent question might be, which segment of ancient Egyptian society was mummified? We know that it was only a very wealthy few, the elite of the time. Historians all note that the elite of the time had three meals a day and had a rich diet, high in meat. So, perhaps the atherosclerosis is not such a surprise after all. It is of perhaps even more interest to look at the post mortem studies on 500yr old Inuit, their bodies having been perfectly preserved in the ice. Their diet was exclusively meat and fat and usually raw. The evidence of extensive atherosclerosis and osteoporosis is striking, especially in subjects aged around 45yrs old at the time of death. There was no bread to blame the CVD on here....
As for the isotope ratio work, well it all sounded convincing. I saw this with work by Michael Richards in the film "The Perfect Human Diet" and I was incredibly impressed and began to think that perhaps we did eat mostly meat. However, as with many things in life, the nitrogen isotope ratio is not quite as straightforward as Dr Eades would have us believe. The principle is that the lighter isotope (14N) is preferentially excreted in the urine and thus as one moves “up the food chain” then the ratio should increase. However, there are many potential confounding factors, such as water scarcity which alter the metabolic process to favour a concentration of 15N in the body, irrespective of what the animal eats. If we rely upon the isotopic data, we find that the gazelle eats more meat than the lion and the Pygmys eat more meat than the Jaguar. When this is combined with the known kill rate of even the best hunter gatherers (around 30%) it quickly becomes clear that it is perhaps unwise to use this data to promote the idea of Palaeolithic man eating mainly meat.
This may give a clearer idea of what the Paleolithic was probably like: ua-cam.com/video/FNIoKmMq6cs/v-deo.html
Stephen Saberi I could be referencing the incorrect study, but didn’t the Greenland Inuit study find that they had low rates of cardiovascular death regardless of similar levels of atherosclerosis.
@@bishamuesmus301 There have been quite a number of studies of the Inuit over the last two to three decades. Some of them have been meta analyses and others have been clinical/observational in nature. There is a consistent pattern of high levels of atherosclerosis amongst the population. There seems to be quite a wide disparity in reported rates of Ischaemic Heart Disease and Cardiac Death across the various papers. Some have posited (probably quite correctly) that due to the isolated nature of the populations, not all IHD/CD events are recorded and autopsy data not as reliable as in more populated areas. There are known genetic adaptions in the Inuit to the high fat diet. However, the Inuit are acknowledged to have a higher than average rate of CVD, specifically stroke and stroke related death. They also have a lower life expectancy than the Western comparison population - be they Danes or Canadians.
This of course is a modern more western influenced populace, which drinks and smokes a lot and so is not truly representative of the original Inuit lifestyle. That's why the autopsy findings from the frozen Inuit dating back 500-1600yrs is so relevant. This clearly shows extensive atherosclerosis throughout the body by around age 45yrs, together with well developed osteoporosis.
What is relevant and important is that all the information shows clearly that a diet high in animal fat results in fatty streaks and CVD - not really a poster-child for the high fat movement.
@@stephensaberi5822 Modern Inuits do not eat a traditional diet anymore, and most of them haven't for hundreds of years. Their diets have been changed with the introduction of easy to get and inexpensive "foods" like wheat flour, sugar, and vegetable oils. Rather than eating JUST fatty meats, they have begun eating fatty meats along with sweets and breaded/fried foods. The combination of high fats and high carbs is the worst diet as the carbohydrates oxidize the fats. And THAT is what causes heart disease.
Go back to the pre-contact Inuit and you will find that the cases of heart disease are basically zero. That doesn't mean it never happened, but it was rare. And that autopsy study you keep referencing is not all that convincing if you actually read it. There was only 1 of the 5 bodies that showed evidence of heart disease. She was a middle aged woman who also showed evidence of an infection in the heart AND had suffered from pneumonia earlier in life. Atherosclerosis is not always only caused by a poor diet. IT can also be caused by illnesses that increase arterial inflammation, which a heart infection and pneumonia definitely could.
Either way. Finding just 1 ancient Inuit with heart disease hardly proves anything one way or the other. All you can prove is that one individual had heart disease. That's it.
As far as your comment about the Egyptians, Dr Eades addresses that in this very lecture. You are only assuming that all of the data was obtained from mummies. It wasn't. Much of the data was obtained from actual remains from "peasants", and from medical records and texts. The fact that so many ancient Egyptians suffered from heart attacks is well known and well documented. Not just by modern historians, but by the ancient Egyptians themselves.
We KNOW what the ancient Egyptians ate across all of the socio-economic classes. The staple was bread. If you lived in ancient Egypt, no matter how rich or powerful you were, you were eating a lot of bread and very little meat. As Dr Eades even pointed out, even the mummies who were supposed to be rich and eating meat all day long showed through isotope ratio testing that they ate MUCH less meat than modern Europeans do. Only roughly 30% of the protein they did eat, which was not very much, came from animal flesh. Meaning in their total diet, animal flesh was less than 5% of their diet. And the animals they did eat were not high in fat. It was mostly water foul and chicken, which are lean meats.
Also, if you were a rich pharaoh who ate primarily meat, you would not have the ground down and flattened teeth that the commoners had from eating all that sand infused bread. Yet every single mummy does have the ground down teeth from eating large amounts of sand infused bread.
So how would explain all of that?
Excellent rebuttal.
Most kind! I'm just summarising some excellent work by experts in the field!.@@itzakpoelzig330
Starch carbohydrates have their place in certain high intensity sports, that has to be said
Theoretically you could also go with fruit carbohydrates
Actually you could just be fat adapted.
@@JD-rc6lq I’ve tried weight training previously whilst on keto, and the lack of glycogen affected my performance considerably
@Shadow Goal and individual variability are consideration. Luis Villasenor and his keto gains website is a good source. Fat adaptation is 3 - 6 months. Unless folks are professional atheltes health should be prioritized over performance, and even then...
I tried eat less carbo but my performance went too worse. Good carbo is the energy we need to do sports.
You probably weren't getting enough electrolytes. You need to have more salts, preferably those with trace minerals (magnesium and potassium) pink salt is good for that. Also you should up your omega fats intake, specifically omega 3s. You can get those in fish. You'll feel a little less energetic for the first week while you deplete the glycogen in your liver. After that you should feel a lot more energetic. As long as you have under 50 grams of carbs a day. If you have more than 50 you will be in a weird spot where you deplete your carbs for energy but your body isn't good at burning fat for energy yet so you don't feel energetic.
Agree with Noel. If you're drinking plain water, you're doing keto wrong.
And apart from the things already mentioned, it takes up to sometimes a year to adapt to fat metabolisim. Nothing to be done in a couple of days.
Thats withdrawal. Carnivore will bring you to the next level once you get through it. All the best brother!
Absolutely not! You aren’t be able.
Good stuff but please one day switch to alien seed theory, micro biology complexity has mathematically disproved random evolution, stop looking ridiculous.
Sir this is a Wendy's
p0ddie 😂
Really? And where did those seedy aliens come from you genius?
@@paulbenedict1289 These cats.....Genesis 6:4 - There were giants on the earth in those days, and also afterward, when the sons of God came in to the daughters of men and they bore children to them. Those were the mighty men who were of old, men of renown.
Alien seed theory is definitely more mathematically supported than lineage from apes, but that does not refute what he is saying. His morphological and gut comparisons betwern herbivorous apes and humans still stands.
