Facultative Carnivore

Facultative Carnivore describes the concept of animals that are technically omnivores but who thrive off of all meat diets. Humans may just be facultative carnivores - who need no plant products for long-term nutrition.

The Northern Copper Inuit - A History

GreatWhiteOncomingSquare.jpg

The modernization of the Inuit of the Holman region is described. Inuit are lent a debt and can no longer engage in midwinter subsistence hunting when trapping foxes. Trapping was fully entrenched by the 1940's in the Holman region and people were eating sugar and flour instead of seals, caribou, and polar bears.

As the Inuit of the Holman region developed a taste for trade items such as tea, sugar, tobacco, and flour, they began to rely more heavily on fur trapping as a means to purchase these items. The transition from traditional ways was undoubtedly assisted by the Copper Inuit's contact with the western Inuit (or Walliningmiut), who had developed a reputation for being superb trappers. Increased dependence upon trapping, however, changed the Inuit economy. Since trappers had to tend their traplines during the winter, they had less time to devote to midwinter subsistence activities such as sealing, caribou hunting, and polar bear hunting. The more involved people became in trapping, the more dependent they became upon goods purchased at the trading posts. Moreover, the size of dogteams increased. In the early part of the century, anthropologist Diamond Jenness had noted that the typical Copper Inuit family rarely owned more than two or three dogs (Jenness 1922:118). Trapping, however, required greater mobility and hence a larger number of dogs per active trapper. Inuit families trapping for the fur trade had a larger number of dogs to care for and feed. Fortunately for them, the introduction of rifles and fishnets helped to increase their efficiency and trapper families were able to feed both themselves and their dogs.

This process of economic change occurred at different rates for the Holman and Coppermine regions. The Copper Inuit around Coppermine and Read Island made the transition much earlier than the people of Prince Albert Sound. By the 1940s, however, trapping was firmly entrenched in the Holman region.

Although the trading posts provided Inuit trappers with valued goods which presumably made their lives easier, the relationship between trapper and trader was not always to the benefit of the trapper. As Peter Usher (1965:62) notes:

The relationship of the Eskimo to the trader became virtually that of a bonded servant. To trap initially the Eskimo had to be supplied with traps, and generally a rifle and other gear. Having no means to pay for this outfit, he went in "debt" to the trader, and settled his account the following spring by bringing in his catch of furs. Both the availability of the white fox and its market price fluctuated considerably, and in some years the Eskimo was unable to pay his debts. This indebtedness prevailed for almost thirty years, until other sources of cash became available to the Eskimos.

The Northern Copper Inuit - A history

Jenness is amazed at the Copper Inuit's energy and patience and endurance, perhaps indicating the results of their superb diet, but also the skills needed to thrive in such an inhospitable place.

Early chroniclers of Copper Inuit culture were also impressed with their energy, patience, and endurance. As Jenness (1922:235) wrote:

The Copper Eskimos think nothing of spending 24 hours on a hunt, tramping continually over stony hills without a morsel of food, and with only a few short halts to rest their limbs and look about them. In Spring I've seen them spend whole days fruitlessly digging one hole after another through the thick ice of the lakes and drinking their lines without ever getting a bite. In Winter they sit for hours over there seal holes even in howling blizzard where the temperature is 30 and more below zero Fahrenheit. The patience instilled in them by hunting become so ingrained in their very natures and permeates all their social life, so that tolerance and forbearance are two of the most marked features in Eskimo Society.

The Treatment of Diabetes Mellitus

GreatWhiteOncomingSquare.jpg

Dr Joslin explains that Eskimos can "get along very comfortably upon 52 grams" of carbohydrate a day which "should greatly encourage diabetic patients"

Carbohydrate.- 

From the preceding statements it will be seen that 55 per cent of the energy of the diet of the normal individual consists of carbohydrate . These figures are only approximate , but they leave no doubt as to how large a place sugar and starch occupy in the daily ration. (See p.415.) What percentage of carbohydrate is furnished by sugar is problematical . We do know, however, that the average individual was supposed to consume 84 pounds of cane sugar during the year 1921. This would amount to 105 grams, or 0.2 pounds, per day, which would amount to about one - fourth of the carbohydrate calories. 


The proportion of carbohydrate in the normal diet varies in different countries, reaching its maximum in the tropics and its minimum in the arctic zones. The people in India take 484 grams carbohydrate daily , while the Eskimos get along very comfortably upon 52 grams . Table 159 is arranged by modifying somewhat a similar table of Lusk's. It shows well the adaptability of different races to different diets . That the Eskimos live upon 52 grams of carbohydrate daily should greatly encourage diabetic patients . All who treat diabetics should be very thankful that there is a race of Eskimos through which proof is afforded that it is perfectly possible to maintain life on a diet in which carbohydrate is largely replaced by fat. The composition of the diet also varies in the same race from time to time and this has been interestingly described by Mendel.


Attention has already been called to the increase in the consumption of sugar in the United States during the last century. Rübner noted that the consumption of meat per capita in Germany had risen three and one - half times during a hundred years prior to the war. The effects of undernutrition during the war were manifest generally in Europe and America, but the total dietary restriction obscures the results of qualitative changes. (See p115.)

A Carnivorous Diet in the Treatment of Flagellate Diarrhea in Journal of the American Medical Association

GreatWhiteOncomingSquare.jpg

Dr Hegner explains that an all meat carnivorous diet can be used to treat flagellate diarhhea but admits there have only been a few anecdotes.

A Carnivorous Diet in the Treatment of Flagellate Diarrhea - Robert W. Hegner. Jour. Am. Med. Assn., 83, 23. 1924


In searching for a method of control of intestinal disturbances caused by the presence of protozoa it has been found that carnivorous mammals are rarely reported as having intestinal protozoa, in omnivorous mammals it is less rare, and herbivorous mammals oftne have a variety of spices present in great numbers.

From a study of lower animals evidence has been obtained. showing that a carnivorous diet is unfavorable for the harboring within the intestines of flagellates of the genera Giardia (Lamblia) and Trichomonas. Physicians can determine the effect of a similar diet on patients having flagellate diarrhea or amebic dysentary.


There have been a limited number of cases of flagellate diarrhea studied where therer was a response to the treatment on a meat diet. However, more data is necessary before making a definite statement regarding the value of a carnivorous diet for eradicating the various species of intestinal protozoa. The readiness with which different forms of protozoa are affected is dependent upon their habitat. Observation and experiments indicate that the forms which live in the large intestine are the ones most quickly affected. 


Menus which are suitable for use by physicians in research along this line have been prepared by McCollum and Simonds. A plea is made that medical men who have control of patients for a considerable time test the effects of a carnivorous diet on the intestinal protozoa of man.

Health Conditions and Disease Incidence among the Eskimos of Labrador

GreatWhiteOncomingSquare.jpg

Dr Hutton: I have not seen or heard of a case of malignant new growth in an Eskimo.

I shall quote and summarize the view Dr. Hutton held in 1925 as to the relation of the former Labrador way of life to cancer, to certain other diseases of which he found no case, and to health in general. Most of the following quotations are from Dr. Hutton's Health Conditions and Disease Incidence among the Eskimos of Labrador.

Under the section heading, “Some Diseases Not Observed,” page 35, Dr. Hutton says:

“Some diseases common in Europe have not come under my notice during a prolonged and careful survey of the health of the Eskimos. Of these diseases the most striking is cancer. I have not seen or heard of a case of malignant new growth in an Eskimo. In this connection it may be noted that cookery holds a very secondary place in the preparation of food — most of the food is eaten raw, and the diet is a flesh one; also that the diet is rich in vitamins. The nomadic and open-air life may also play a part.

“I have not seen rickets among the Eskimos, though it occurs rather frequently among the children of European residents ... most European mothers resident on the Labrador coast find themselves unable to suckle their babies — the breasts are full of milk for a few days after birth, and then the supply ceases — the result, no doubt, of the preponderance of tinned and dried foods in the dietary of the European residents. The Eskimo mothers suckle their babies often for two years; the milk supply is plentiful, and the babies grow fat and strong, able to walk at eleven months ...

“I have never observed true asthma in an Eskimo ... Disease of the Fallopian tubes appears to be rare ...

“Appendicitis is another of the diseases which rarely appear among the Eskimos. I have seen one case in a young man, but in one living on ‘settler’ dietary; among the real meat eating Eskimos I have found no record suggestive of the occurrence of this disease ... The settler dietary consists of tea, bread, ship's biscuits, molasses, and salt fish or pork.”

Scattered through Dr. Hutton's writings are references to other diseases, omitted from this section, which were noted by him during the 1902-13 period but which were found only among white settlers or among Eskimos whose way of life had been influenced markedly by whites. Among these troubles scurvy and tooth decay are frequently mentioned.

Dr. Hutton says on page 9: “The Eskimo is meat eater; the vegetable part of his diet is a meager one ... Only the small black waterberry, empetrum nigrum, is eaten to any extent ... In spring the buds of the sedum roseum and the young shoots of the willow, salix argyrocarpa, are gathered and eaten. The Eskimos themselves cultivate no plants whatever, though in their inter course with missionaries they have shown a taste for garden produce, and eat what they can get. Turnips and cabbages are favorites, and are usually eaten raw; but only the few who work in the missionary households have any considerable share in this scanty garden produce. The dandelion, taraxacum, grows in plenty but is mt eaten by the natives. We may, therefore, say that the normal Eskimo dietary is poor in vegetable constituents.

“On the other hand, the native flesh foods are numerous, and of them all the flesh of the seal is most important and the most used ... Plain raw flesh is the Eskimo's favorite food; but seal's flesh is also eaten frozen (raw), dried in the open air without salt, boiled or even rotten ... The blubber, or outer fat of the seal, is usually eaten with the dried meat.

“Other flesh foods, less important because less plentiful than the seal's flesh, are walrus meat, caribou meat, bear, fox, and various birds. These are eaten raw or boiled.

“Fish is the staple food during the warmer part of the year. Trout and cod are to be had in plenty and are eaten either fresh (raw or boiled) or dried without salt. Salted fish is used by the English-speaking settlers in the southern part of the coast, and by the Eskimos who live in contact with them; but as a general rule it may be said that Eskimos do not use salt in their food ... mussels are gathered from the rocks in the spring, and sea-urchins are fished up from the sea bed in the autumn, and both of these are eaten raw.

“A certain amount of carbohydrate food enters the Eskimo dietary; the people obtain flour, ship's biscuits and molasses, and use these particularly when their native flesh foods are scarce. It should be noted that cod liver oil is used considerably; the natives dip their dried fish in it.

“To summarize ... the diet is mainly flesh and fish; vegetable foods are decidedly scanty.”

Longevity is touched upon in Health Conditions in several places. One such is page 17:

“Old age sets in at fifty and its signs are strongly marked by the time sixty is reached. In the years beyond sixty the Eskimo is aged and feeble. Comparatively few live beyond sixty and only a very few indeed reach seventy. Those who live to such age have spent a life of great activity, feeding on Eskimo foods and engaging in characteristically Eskimo pursuits ... Careful records have been kept by the missionaries for more than a hundred years ...”

(Further details of Labrador Eskimo length of life will be found in Chapter 14, “The Longevity of ‘Primitive’ Eskimos.”)

Page 18: “Perhaps the most striking of the peculiarities of the Eskimo constitution is the great tendency to hemorrhage ... young and old alike are subject to nose-bleeding, and these sometimes continue for as much as three days and reduce the patient to a condition of collapse.” Dr. Hutton says that menorrhagia and haemoptysis are also common.

Page 20: “Scurvy in its typical form is rare among the Eskimos. I have seen but one case of it in a pure-blooded Eskimo: and the fact that the other members of that woman's household show an unusually strong tendency to boils, abscesses and ulcers, leads me to attribute the scurvy to the adoption, in the case of that household, of a semi-European dietary.

“Seal's flesh, especially when eaten raw, has reputed anti-scorbutic properties. Certainly, when seal's flesh is plentiful the health of the Eskimos is good; and the tribe in the far north, who get very few berries or other forms of vegetable food, but who have seals all the year round, are free from true scurvy ...”

Page 21: “In passing, it is interesting to note the effect on the Eskimo of a European dietary adopted as a habit of life.

“On the southern part of the Labrador coast there are numbers of English-speaking settlers ... these poor folks live for the most part on tea, bread and salt fish or pork, and among them scurvy is common ... The Eskimos living among these settlers have to an extent adopted the ‘settler’ dietary instead of the normal flesh diet of the true Eskimos; and not only does scurvy occur among them in its typical form, but their physique is less robust than is that of their northern brethren ... They endure fatigue less easily, and their children are puny and feeble.”

In various places Dr. Hutton agrees with the common view that an important benefit from European contact is the decrease of childbirth mortality, both of mothers and of children. He considers tuberculosis to be probably of white introduction and to have been the worst killer during his time on the Labrador.

Page 66: “Europeanization, especially in matters of foods, is a detrimental influence of comparatively recent development, but an influence of great importance ... Hospital experience among the Eskimos has proved beyond doubt that the native foods are best suited to the native constitution ...”

We have gone so extensively into Dr. Hutton's views on the general health of the Labrador Eskimo, before and during his 1902-13 clinical experience, because of the impression derived from the total of his later writings — that he considered the extreme rarity or absence of native cancer, in which he believed, to be a by-product of an over-all good Eskimo health, which deteriorated with the advance of Europeanization.

Neanderthal diet at Vindija and Neanderthal predation: The evidence from stable isotopes

The isotope evidence overwhelmingly points to the Neanderthals behaving as top-level carnivores, obtaining almost all of their dietary protein from animal sources

Archeological analysis of faunal remains and of lithic and bone tools has suggested that hunting of medium to large mammals was a major element of Neanderthal subsistence. Plant foods are almost invisible in the archeological record, and it is impossible to estimate accurately their dietary importance. However, stable isotope (􏰃13C and 􏰃15N) analysis of mammal bone collagen provides a direct measure of diet and has been applied to two Neanderthals and various faunal species from Vindija Cave, Croatia. The isotope evidence overwhelmingly points to the Neanderthals behaving as top-level carnivores, obtaining almost all of their dietary protein from animal sources. Earlier Neanderthals in France and Belgium have yielded similar results, and a pattern of European Neander- thal adaptation as carnivores is emerging. These data reinforce current taphonomic assessments of associated faunal elements and make it unlikely that the Neanderthals were acquiring animal protein principally through scavenging. Instead, these findings portray them as effective predators.


Stable Isotope Analyses.

Mammal bone collagen δ13C and δ15N values reflect the δ13C and δ15N values of dietary protein (14). They furnish a long-term record of diet, giving the average δ13C and δ15N values of all of the protein consumed over the last years of the measured individual's life. δ13C values can be used to discriminate between terrestrial and marine dietary protein in humans and other mammals (15, 16). In addition, because of the canopy effect, species that live in forest environments can have δ13C values that are more negative than species that live in open environments (17). δ15N values are, on average, 2–4‰ higher than the average δ15N value of the protein consumed (18). Therefore, δ15N values can be used to determine the trophic level of the protein consumed. By measuring the δ13C and δ15N values of various fauna in a paleo-ecosystem, it is possible to reconstruct the trophic level relationships within that ecosystem. Therefore, by comparing the δ13C and δ15N values of omnivores such as hominids with the values of herbivores and carnivores from the same ecosystem, it is possible to determine whether those omnivores were obtaining dietary protein from plant or animal sources.

FOCUS: Gough’s Cave and Sun Hole Cave Human Stable Isotope Values Indicate a High Animal Protein Diet in the British Upper Palaeolithic

We were testing the hypothesis that these humans had a mainly hunting economy, and therefore a diet high in animal protein. We found this to be the case, and by comparing the human δ15N values with those of contemporary fauna, we conclude that the protein sources in human diets at these sites came mainly from herbivores such as Bos sp. and Cervus elaphus

We undertook stable isotope analysis of Upper Palaeolithic humans and fauna from the sites of Gough's Cave and Sun Hole Cave, Somerset, U.K., for palaeodietary reconstruction. We were testing the hypothesis that these humans had a mainly hunting economy, and therefore a diet high in animal protein. We found this to be the case, and by comparing the human δ15N values with those of contemporary fauna, we conclude that the protein sources in human diets at these sites came mainly from herbivores such as Bos sp. and Cervus elaphus. There are a large number ofEquus sp. faunal remains from this site, but this species was not a significant food resource in the diets of these Upper Palaeolithic humans.


If the humans hunted and consumed mainly horse, then their 15N values should be c. 3–5‰ (Equus 15N value of 0·7‰+enrichment of 2–4‰). Instead, their 15N values make more sense if they lived mostly off Bos and Cervus elaphus (Bos and Cervus values of c. 3‰+enrichment of 2–4‰=the observed values c. 6–7‰). It is also possible that other species, including Rangifer tarandus, were consumed by these individuals. Rangifer tarandus has 15N values similar to Cervus elaphus (Richards, 1998), and has more positive 13C values, which may explain the observed slight enrichment in the human 13C values. A number of artefacts made from Rangifer tarandus have been found at Gough’s, but there is no other evidence that this species was being exploited for food
