Törmäsin vastikään erästä keskustelufoorumia lukiessani Weston A. Pricen ottamiin kuviin alkuperäiskansojen hampaista. Ketjussa kirjoittaja käytti kuvia todisteena täysjyväviljan turmiollisesta vaikutuksesta.
Pricen kirjassa ei kyllä sellaisesta puhuta sanaakaan: Weston A. Price: Nutrition and Physical Degeneration
It might be expected that such wonderfully formed teeth would maintain so high an immunity to dental caries that their proud possessors would never be troubled with tooth decay. This, unfortunately, is not the case, a fact of great significance in evaluating our modern theories of the causes of dental caries. When these adult Eskimos exchange their foods for our modern foods, which we will discuss in Chapter 15, they often have very extensive tooth decay and suffer severely. This is clearly illustrated in Fig. 11, for these Eskimos’ teeth had been seriously wrecked by tooth decay. They had been living on modern foods and were typical of a large number who are in contact with the Bering Sea ports. Their plight often becomes tragic since there are no dentists in these districts.
Toisin sanoen: eskimoitten hampaisiin ilmestyi kariesta ja epämuodostumia sen jälkeen kun he joutuivat tekemisiin länsimaisen ruoan kanssa. Sen Price määrittelee monessa eri yhteydessä pitkälle jalostetuksi, purkitetuksi, sokeria ja valkoisia jauhoja sisältäväksi ruoaksi, joka sisältää eri ravinteita huomattavasti vähemmän kuin alkuperäiskansojen perinteinen ruokavalio.
There are certain characteristics of the various dietaries of the primitive races, which are universally present when that dietary program is associated with a high immunity to disease and freedom from deformities. In general, these are the foods that provide adequate sources of body-building and body-repairing material. The use by primitives, of foods relatively low in calories has resulted in forcing them to eat large quantities of these foods, in order to provide the heat and energy requirements of the body. The primitives have obtained, often with great difficulty, foods that are scarce but rich in certain elements. In these rare foods were elements which the body requires in small quantities, including minerals such as iodine, copper, manganese and special vitamins. In connection with the vitamins it should be kept in mind that our knowledge of these unique organic catalysts is limited. The medical profession and the public at large think of vitamin D as consisting of just one chemical factor, whereas, investigations are revealing continually new and additional factors.
Esimerkiksi Pricen tutkima yhteisö Sveitsissä eli pääasiassa oman pellon ruisleivällä, maidolla ja kasviksilla. Lihaa he söivät kerran viikossa:
When we discuss the successful dietary programs of the various groups from the standpoint of their ability to control tooth decay and prevent deformity we find that for the people in the high and isolated Alpine valleys their nutrition is dependent largely on entire rye bread and dairy products with meat about once a week and various vegetables, fresh in the summer season and stored for the winter season. An analysis in my laboratory of the dairy products obtained from the Loetschental Valley in Switzerland through a series of years has shown the vitamin content to be much higher than the average throughout the world for similar foods during the same seasons. The milk in these high valleys is produced from green pasturage and stored green hay of exceptionally high chlorophyll content. The milk and the rye bread provided minerals abundantly.
Ulko-Hebrideillä väestö eli pääasiassa merenelävillä:
The diet of the people in the Outer Hebrides which proved adequate for maintaining a high immunity to dental caries and preventing deformity consisted chiefly of oat products and sea foods including the wide variety of fish available there. This diet included generally no dairy products since the pasture was not adequate for maintaining cattle. Oat grain was the only cereal that could be matured satisfactorily in that climate. Some green foods were available in the summer and some vegetables were grown and stored for winter. This diet, which included a liberal supply of fish, included also the use of livers of fish. One important fish dish was baked cod’s head that had been stuffed with oat meal and chopped cods’ livers. This was an important inclusion in the diets of the growing children. The oats and fish, including livers, provided minerals and vitamins adequate for an excellent racial stock with high immunity to tooth decay.
Eskimot eli inuitit kuten heitä nykyisin kutsutaan söivät mereneläviä ja myös niiden sisäelimiä:
For the Eskimos of Alaska the native diet consisted of a liberal use of organs and other special tissues of the large animal life of the sea, as well as of fish. The latter were dried in large quantities in the summer and stored for winter use. The fish were also eaten frozen. Seal oil was used freely as an adjunct to this diet and seal meat was specially prized and was usually available. Caribou meat was sometimes available. The organs were used. Their fruits were limited largely to a few berries including cranberries, available in the summer and stored for winter use. Several plant foods were gathered in the summer and stored in fat or frozen for winter use. A ground nut that was gathered by the Tundra mice and stored in caches was used by the Eskimos as a vegetable. Stems of certain water grasses, water plants and bulbs were occasionally used. The bulk of their diet, however, was fish and large animal life of the sea from which they selected certain organs and tissues with great care and wisdom. These included the inner layer of skin of one of the whale species, which has recently been shown to be very rich in vitamin C. Fish eggs were dried in season. They were used liberally as food for the growing children and were recognized as important for growth and reproduction. This successful nutrition provided ample amounts of fat-soluble activators and minerals from sea animal life.
Pohjois-Kanadassa elävät intiaanit söivät riistaa (sisäelimiä) ja kasviksia:
For the Indians living inside the Rocky Mountain Range in the far North of Canada, the successful nutrition for nine months of the year was largely limited to wild game, chiefly moose and caribou. During the summer months the Indians were able to use growing plants. During the winter some use was made of bark and buds of trees. I found the Indians putting great emphasis upon the eating of the organs of the animals, including the wall of parts of the digestive tract. Much of the muscle meat of the animals was fed to the dogs. It is important that skeletons are rarely found where large game animals have been slaughtered by the Indians of the North. The skeletal remains are found as piles of finely broken bone chips or splinters that have been cracked up to obtain as much as possible of the marrow and nutritive qualities of the bones. These Indians obtain their fat-soluble vitamins and also most of their minerals from the organs of the animals. An important part of the nutrition of the children consisted in various preparations of bone marrow, both as a substitute for milk and as a special dietary ration.
Itä- ja Keski-Afrikan heimot söivät isoja määriä bataattia, papuja, ja jonkin verran viljaa, ja kalaa silloin kuin mahdollista. Vilja jauhettiin yleensä juuri ennen ruoan valmistamista:
The native tribes in eastern and central Africa, used large quantities of sweet potatoes, beans, and some cereals. Where they were living sufficiently near fresh water streams and lakes, large quantities of fish were eaten. Goats or cattle or both were domesticated by many tribes. Other tribes used wild animal life quite liberally. Some very unique and special sources of vitamins were used by some of these tribes. For example, in certain seasons of the year great swarms of a large winged insect develop in Lake Victoria and other lakes. These often accumulated on the shores to a depth of many inches. They were gathered, dried and preserved to be used in puddings which are highly prized by the natives and are well spoken of by the missionaries. Another insect source of vitamins used frequently by the natives is the ant which is collected from great ant hills that in many districts grow to heights of ten feet or more. In the mating season the ants develop wings and come out of the ant hills in great quantities and go into the air for the mating process. These expeditions are frequently made during or following a rain. The natives have developed procedures for inducing these ants to come out by covering over the opening with bushes to give the effect of clouds and then pounding on the ground to give an imitation of rain. We were told by the missionaries that one of the great luxuries was an ant pie but unfortunately they were not able to supply us with this delicacy. Parts of Africa like many other districts are often plagued by vast swarms of locusts. These are gathered in large quantities, to be cooked for immediate use or dried and ground into a flour for later use. They provide a rich source of minerals and vitamins. The natives of Africa used the cereals maize, beans, linga linga, millet, and Kaffir corn, cooked or roasted. Most of these were ground just before cooking.
Australiassa alkuperäisheimot söivät mereneläviä, juureksia, kasviksia ja hedelmiä:
The native diet of the tribes living in the islands north of Australia consisted of liberal quantities of sea foods. These were eaten with a variety of plant roots and greens, together with fruits which grew abundantly in that favorable climate. Few places in the world have so favorable a quantity of food for sea-animal life as these waters which provide the richest pearl fisheries in the world. This is evidence of the enormous quantity of shell-fish that develop there.
Alfred Vogelin havainnot hänen matkoillaan alkuperäiskansojen parissa esittävät aivan samaa: ihmisten terveys pysyi hyvänä niin kauan kuin he pysyttäytyivät perinteisessä paikallisessa ruokavaliossa. Kun he alkoivat omaksua länsimaisia ruokailutottumuksia (jalostetut, purkitetut, puhdistettua sokeria ja valkoisia jauhoja sisältävät ruoat), heidän terveydentilansa alkoi samaa vauhtia huonontua.
Lyhyesti: ihminen voi elää monenlaisilla ruokavalioilla terveenä. Vain länsimainen pitkälle jalostettu ruoka ei kuulu tähän joukkoon. Osa elää vähillä hiilihydraateilla, osa runsaammilla, mutta yhtäkaikki, olennaista on se, että ruoka tuotetaan tai hankitaan pyydystämällä, keräämällä jne. paikan päällä. Ravintosisältö on se tärkein tekijä, ei suinkaan eri makroravinteiden suhteet ja hiilihydraattien grammat.
