Here's an excerpt from Dr. Price's book:
"... It is of interest that the diets of the primitive groups which have shown a very high immunity to dental caries and freedom from other degenerative processes have all provided a nutrition containing at least four times these minimum requirements; whereas the displacing nutrition of commerce, consisting largely of white-flour products, sugar, polished rice, jams, canned goods, and vegetable fats have invariably failed to provide even the minimum requirements.
In other words the foods of the native Eskimos contained 5.4 times as much calcium as the displacing foods of the white man, five times as much phosphorus, 1.5 times as much iron, 7.9 times as much magnesium, 1.8 times as much copper, 49.0 times as much iodine, and at least ten times that number of fat-soluble vitamins.
For the Indians of the far North of Canada, the native foods provided 5.8 times as much calcium, 5.8 times as much phosphorus, 2.7 times as much iron, 4.3 times as much magnesium, 1.5 times as much copper, 8.8 times as much iodine, and at least a ten fold increase in fat-soluble activators. For brevity, we will apply the figures to calcium, phosphorus, magnesium, iron and fat-soluble activators in order.
The ratio in the Swiss native diets to that in the displacing diet was for calcium, 3.7 fold; for phosphorus, 2.2 fold; for magnesium, 2.5 fold; for iron, 3.1 fold; and for the fat-soluble activators, at least ten fold.
For the Gaelics in the Outer Hebrides, the native foods provided 2.1 times as much calcium, 2.3 times as much phosphorus, 1.3 times as much magnesium, and 1.0 times as much iron; and the fat-soluble activators were increased at least ten fold.
For the Aborigines of Australia, living along the eastern coast where they have access to sea foods the ratio of minerals in the native diet to those in the displacing modernized foods was, for calcium, 4.6 fold; for phosphorus, 6.2 fold; for magnesium, 17 fold; and for iron 50.6 fold; while for the fatsoluble activators, it was at least ten fold.
The native diet of the New Zealand Maori provided an increase in the native foods over the displacing foods of the modernized whites of 6.2 fold for calcium, 6.9 fold for phosphorus, 23.4 fold for magnesium, 58.3 fold for iron; and the fatsoluble activators were increased at least ten fold.
The native diet of the Melanesians provided similarly an increase over the provision made in the modernized foods which displaced them of 5.7 fold for calcium, 6.4 fold for phosphorus, 26.4 fold for magnesium, and 22.4 fold for iron; while the fat-soluble activators were increased at least ten fold.
The Polynesians provided through their native diet for an increase in provision over that of the displacing imported diets, of 5.6 fold for calcium, 7.2 fold for phosphorus, 28.5 fold for magnesium, 18.6 fold for iron; and the fat-soluble activators were increased at least ten fold.
The coastal Indians of Peru provided through their native primitive diets for an increase in provision over that of the displacing modernized diet of 6.6 fold for calcium, 5.5 fold for phosphorus, 13.6 fold for magnesium, 5.1 fold for iron; and an excess of ten fold was provided for fat-soluble vitamins.
For the Indians of the Andean Mountains of Peru, the native foods provided an increase over the provision of the displacing modern foods of S fold for calcium, 5.5 fold for phosphorus, 13.3 fold for magnesium, 29.3 fold for iron; and an excess of at least ten fold was provided for fat-soluble vitamins.
For the cattle tribes in the interior of Africa, the primitive foods provided an increase over the provision of the displacing modernized foods of 7.5 fold for calcium, 8.2 fold for phosphorus, 19.1 fold for magnesium, 16.6 fold for iron and at least ten fold for fat-soluble activators.
For the agricultural tribes in Central Africa the native diet provided an increase over the provision of the displacing modern diet of 3.5 fold for calcium, 4.1 fold for phosphorus, 5.4 fold for magnesium, 16.6 fold for iron and ten fold for fat-soluble activators...."
that's from chapter 15.
