Grass-Fed Animate Being Foods Together With Diseases Of Civilization: Cardiovascular Disease In Ancient Civilizations

Vilhjalmur Stefansson was an Artic explorer known for his observations on the traditional living Inuit-Eskimo, which he lived together with in the winter of 1906-1907 inward the Mackenzie Delta of Canada. Stefansson asserted that during this fourth dimension he subsisted on traditional Inuit fare, based nearly only on flesh. In part based on less than extensive observations of the wellness of the Inuit, Stefansson hypothesized that a number of chronic too degenerative diseases, including cancer are diseases of culture which tin live prevented past adherence to a pre-mod diet and lifestyle. However, Stefansson did not propose that alone flesh based dietary patterns, such every bit that consumed by the traditional living Inuit, simply likewise primarily vegetarian diets, such equally that consumed past the Hunza may protect against such diseases.one 

The term diseases of culture, which Stefansson has contributed to the popularization of is ofttimes referred to past proponents of Low-Carb, Paleo, Primal in addition to Weston A. Price Foundation type diets. Many of these proponents accept extrapolated express suggestive prove that obesity, type ii diabetes, coronary heart illness, certain cancers, and a number of other chronic and degenerative diseases were uncommon during the Paleolithic menstruation to suggesting that foods derived from naturally raised, grass-fed animals, as was consumed past Paleolithic humans must thence somehow render protection against these so-called diseases of culture. Many of these proponents have besides claimed that a vast number of scientific studies that accept been used equally bear witness to conclude that animate being foods increment the run a risk of such diseases take been complicated by confounding of other unhealthy foods in addition to lifestyle factors, or by the role of unnaturally raised brute foods. This series of posts volition examine the testify to help determine whether these claimed confounding variables tin can really explicate the testify linking beast foods amongst sure chronic too degenerative diseases, oft referred to equally diseases of civilization, merely besides equally western diseases, lifestyle diseases together with diseases of affluence.

In 1928, Stefansson and his colleague Karsten Anderson participated in a monitored experiment partly funded by the sum industry inwards which they consumed a flesh exclusive diet for the flow of ane yr. Although the researchers concluded that these ii men were inwards practiced health throughout the experiment, Anderson experienced a severe pinnacle in blood cholesterol, with measurements as high as 800 mg/dl on one occasion, which returned to pre-experiment levels subsequently resuming a higher saccharide diet.ane six This should make these populations suitable to written report the hypothesis that naturally raised beast foods protect against cardiovascular illness.

Contrary to claims of the traditional living Inuit being immune from cardiovascular disease, show of severe atherosclerosis has been identified in several frozen mummies of Alaskan Inuit dating back to 400 CE in addition to 1520 CE, both instances predating European contact.vii viii Atherosclerosis has besides previously been identified inwards several artificially prepared mummies of Aleut-Unangan hunter gatherers who lived in the 18th century inwards the Aleutian Islands inwards Alaska.ix x Recently the HORUS report, which examined an additional 5 recovered mummies of Unangan hunter gatherers who lived in the mid and late 19th century plant definite prove of atherosclerosis inwards several major arteries inward all 3 who were over the age of 25.eleven

When considering the findings from all of these Alaskan Inuit in addition to Aleut mummies it becomes evident that these Alaskan natives probable experienced a greater incidence of atherosclerosis, particularly given the young hateful historic period compared to the iii other ancient populations studied inward the HORUS written report. Unlike the Alaskan natives, these other iii populations, which were the ancient Egyptians, ancient Peruvians in addition to Ancestral Puebloans adept agriculture and consumed grains. 

In improver to evidence of atherosclerosis from native Alaskan mummies, reports from medical officers supply further prove of unfavorable rates of cardiovascular disease amid the Inuit earlier the rapid transition to the western diet. In 1940, based on decades of clinical practise together with reviewing reports of medical officers dating all the way dorsum 175 years agone, Bertelsen, who is considered the father of Greenland epidemiology stated in regards to the mortality patterns amid the Greenland Inuit that: 
...arteriosclerosis together with degeneration of the myocardium are quite mutual conditions amongst the Inuit, in particular considering the depression mean historic period of the population.12
Bjerregaard too colleagues performed a literature review for studies addressing the incidence of atherosclerosis as well as cardiovascular illness amidst the Inuit of Alaska, Canada as well as Greenland spanning from the 1930s to more recent decades. The researchers establish that the incidence of atherosclerosis was mostly like to that of other western populations that suffered from high rates of cardiovascular illness. Mortality from stroke was institute to be even higher, in addition to mortality from all cardiovascular diseases combined was found to be like or fifty-fifty higher amid the Inuit. The researchers also institute that mortality from coronary middle affliction amidst the Inuit was not significantly different after adjusting for sick-defined causes of cardiovascular decease, suggesting that the substantial proportion of cardiovascular deaths existence classified as ‘garbage codes’, particularly inwards Greenland may accept hidden a pregnant constituent of deaths from coronary eye disease. The researchers concluded: 
The mortality from all cardiovascular diseases combined is not lower among the Inuit than inwards white comparing populations. If the mortality from IHD [ischemic heart illness] is low, it seems not to be associated amongst a low prevalence of general atherosclerosis. A decreasing tendency inwards mortality from IHD inward Inuit populations undergoing rapid westernization supports the postulate for a critical rethinking of cardiovascular epidemiology among the Inuit in addition to the office of a marine diet inward this population.12
A similar phenomenon to the misclassification of deaths from coronary centre illness among the Inuit populations has too been observed in France, which may largely explicate the and then-called French Paradox. Data from the World Health Organization MONICA Project suggests that the official mortality statistics for France significantly underreport deaths from cardiovascular affliction compared to other countries, amongst deaths from coronary centre affliction existence underestimated by 75%. Other reports advise that this is probable explained past a much higher rate of French doctors classifying deaths every bit due to ‘other causes’ than in other countries.Papua New Guinean highlanders take a smoking prevalence of greater than seventy% for males as well as 20% for females spell besides being exposed to fume for upwardly to twelve hours a day due to the role of centrally placed open wood fires inward their houses which lack both ventilation in addition to chimneys. Despite such a high exposure to hazardous fume it has been observed that the Papua New Guinean highlanders accept amongst the lowest historic period-adjusted incidence of atherosclerosis of whatever studied population. However, dissimilar the Inuit, the Papua New Guinean highlanders traditionally consumed a found based diet amongst carbohydrate supplying more than than ninety% of total free energy intake, predominantly derived from sweet potatoes.26 27

Another population that accept historically been documented to subsist near only on a diet derived from grass-fed, complimentary-ranging animals are the largely nomadic Mongolians. John of Plano Carpini who visited the Mongols inwards the mid-13th century noted:
[The Mongols] have neither bread nor herbs nor vegetables nor anything else, zip but inwardness… They drink mare’sec milk inward really peachy quantities if they have it; they besides drink the milk of ewes, cows, goats too fifty-fifty camels.28
Smith reviewed the literature regarding the wellness of the Mongols from the 13th century too noted that a issue of unfavorable cardiovascular risk factors, including obesity as well as gout were both mutual disorders. Smith went on to country:
Cardio-vascular problems, although non then subject field to diagnosis, may be suspected also.29
In 1925, Kuczynski reported on the nomadic pastoralists of the Kirghiz together with Dzungarian Steppes inward Central Asia too northern Red China that were of Mongolian descent. Similar to the observations of the diet of the nomadic Mongols of the 13th century, Kuczynski observed that these nomadic pastoralists subsisted near entirely on enormous quantities of substance and milk from grass-fed, costless-ranging animals. Other authors take also come up to the same conclusions regarding the composition of the diet of the nomadic pastoralists of the Central Asian Steppes. For example, Tayzhanov asserted:
…the people [of the steppe] lived only on nub, fat too sour milk. Bread was added exclusively after too fifty-fifty and then more or less households did not adopt or consume this nutrient.xxx
Similarly, Barfield asserted:
In skilful legendary way, the pure Central Asian nomads eat alone essence, substance, too milk products preferably ferments. They despise farmers, farming, too grain…31
These findings advise that the diet of these nomadic pastoralists of the Central Asian Steppes was near entirely animate being based, about devoid of grains, legumes as well as refined carbohydrates. This should make these populations also suitable to report the hypothesis that naturally raised beast foods protect against cardiovascular illness. However, not exclusively did Kuczynski discover that these nomadic pastoralists suffered from high rates of obesity and gout similar to the Mongols of the 13th century, Kuczynski's observations farther extended to the diagnosis of cardiovascular illness together with other dietary related disorders. Kuczynski asserted:
They get arteriosclerosis in an intense level in addition to ofttimes at an early on historic period as shown past cardiac symptoms, nervous disordes, typical changes of the peripheral vessels, nephrosclerosis together with, last, apoplectic attacks. Even inward men thirty-two years sometime I oftentimes observed arcus senilis.32
It was likewise observed that inward the 1960s the prevalence of coronary heart illness among the nomadic pastoralists in Xinjiang inwards northern Red China who consumed large quantities of animate being fat from grass-fed, complimentary-ranging animals was more than than vii times higher than that of other populations both within Xinjiang in addition to throughout Communist China which consumed significantly less animate being fatty.33 These observations back up the proffer that cardiovascular illness was common amidst the Mongols of the 13th century who subsisted almost exclusively on a diet based on grass-fed, gratuitous-ranging animals.


Dispelling Grass-Fed Fairy Tales


These findings from populations living earlier the 20th century suggest that similar to the findings from people studied in more modernistic times, a greater intake of minimally refined constitute foods strongly predicts a lower prevalence of atherosclerosis and cardiovascular disease. These findings form doubt on the hypothesis that foods from organic, naturally raised animals protect against cardiovascular illness compared to staple constitute foods. Furthermore, these findings suggest that the traditional living populations that relied predominantly on naturally raised animal based foods suffered from complications related to cardiovascular disease at a relatively immature historic period too are wretched part models for health.

Future posts inwards this serial will farther address how naturally raised animal foods influence cardiovascular illness, besides as other and then-called diseases of culture.
