This is the original 1936 article that started the whole "Inuit Diet" idea. Very good read if you haven't.
Stefansson 3 - Eskimos Prove An All Meat Diet Provides Excellent Health.
Here is an excerpt of a summary:
Comments About Stefansson's Conclusions
Some people who disagree with a low-carbohydrate lifestyle are quick to grasp at some of Stefansson's conclusions as evidence the Eskimos' all meat diet was unhealthy. The Eskimos diet cannot be blamed for Stefansson's concluding remarks.
The Eskimos may have appeared to age more quickly than white Europeans for several reasons:
They were exposed to extreme temperature ranges their entire life.
They may have been exposed to excessive smoke from fires in their huts.
They may have been effected by the reduced amount of sun light during winter months.
The life span of the Eskimos would naturally be shorter than that of other societies for several reasons which have nothing to do with nutrition:
The extreme temperature exposure is expected to cause some percentage of deaths.
The hunting and fishing practices are high risk endeavors that cause deaths by accident.
Fluctuations in food supply are known to have caused starvation among the Eskimos.
Infection was a major cause of death for which the people had little understanding.
The Eskimos had many health advantages compared to white Europeans of their day. These health benefits can be clearly credited to their all meat diet, such as:
Perfect dental health. They had no dental caries within the entire community.
Excellent skeletal health without any signs of osteoporosis.
They had no cancer of any kind.
They had no heart disease or cardiovascular disease of any kind.
They had no intestinal diseases that have been reported by Stefansson or others.
They had no Type 2 diabetes because it is caused by eating carbohydrates.
They had no obesity because obesity is caused by eating carbohydrates.
Stefansson found his health suffering after eating a typical American diet upon his return to New York City. He changed back to the low-carbohydrate, high-fat diet, regained his health and continued in very good health until his death at the age of 83.
The Eskimos proved that our current Recommended Daily Allowance (RDA) for vitamins and minerals must be wrong. The Eskimos ate an all meat and animal fat diet by eating seal, polar bear, caribou, fox, wolf, whale, fish and bird. Their diet would appear to be low in vitamin C and vitamin K, but they did not develop scurvy or develop illnesses as the result of a vitamin C or K deficiency. The Eskimos proved the current nutritional theory of a "balanced diet" is nonsense. Some Eskimo tribes ate primarily polar bear, others primarily seal and others primarily salmon. The most healthy diet has the majority of calories coming from meat and natural animal fats while avoiding carbohydrates.
The ice has always melted at the shoreline in summer along Northern Canada and Alaska. That is why explorer tried to search for the Northwest Passage, a route that was ice free around Northern Canada. The passage is never fully open, but an icebreaker has made the trip from Greenland to Alaska. The Franklin party comprised of two shipped tried to find the passage in 1825. They knew they would be trapped in the ice all winter and prepared for it with their guns, food and lime juice for vitamin C. They all died anyway from scurvy, a disease caused by vitamin C deficiency. The nearby Eskimos would wave to the men on the ships as they went about their daily routine hunting seals, raising babies, taking care of old people and feeding their dogs. They had no guns and ate a 100% meat diet. Professional nutritionists will tell you meat has no vitamin C. That is just another example of brainwashing.
Humans would quickly die on a diet of all fruit or all carbohydrates. Humans would suffer multiple nutritional deficiencies and diseases on a diet of all grains, legumes or rice. Humans live wonderfully healthy on a diet of all meat and natural animal fats which includes the organ meats.
Primitive societies that switched from being primarily meat eating hunters to becoming primarily grain eating farmers suffered a sharp decline in health as proven by multiple studies. The ancient Egyptians are a very good example proving that carbohydrates from whole grains and fruit are disease causing.
Vitamin and mineral food count books cannot be trusted to give the correct amount of vitamins and minerals contained in various foods. Meat is typically ignored as a recommended vitamin or mineral source in favor of fruit and vegetables. In truth, red meat, fowl, fish and sea food are packed with vitamins minerals, essential fatty acids and essential amino acids. Vitamin B12 is only found in meat. When explorers discovered the North American Indians and Eskimos, they found them to be in excellent health even though their diet consisting almost entirely of meat. Nutritionists of the day and modern nutritionists cannot concede the fact that these people did not suffer from scurvy because of a deficiency of vitamin C as expected. The explorers found that fresh meat and pemmican not only prevented scurvy but it cured scurvy in those already suffering from the disease. The Indians and Eskimos lived in excellent health on an all meat diet. The Eskimos that lived in Northern Canada on the Mackenzie River delta ate a diet almost entirely of salmon, caribou and seal. The North American Plaines Indians lived primarily on pemmican, a mixture of lean buffalo meat, dried, shredded or pounded fine and mixed with melted fat. The fat was half internal hard fat and half external soft back fat. This diet grew tough, strong and perfectly healthy children. The content was 80% fat on a calorie basis contrary to the erroneous statements made in numerous books that the Indians ate lean meat. These writers came to this hasty conclusion because buffalo flesh is more lean than beef. The Indians added 50% fat on a volume basis to make the pemmican. The Hudson Bay Company and North West Company (fur trappers and traders) purchased pemmican from the Indians by the ton to supply the fur trappers. The United States Government later moved the Indians to reservations where the Government provided them with grain, flour and sugar as food, instead of meat. The high-carbohydrate diet supplied by the Government destroyed the health of the Indians causing an epidemic of obesity, diabetes, heart disease and cancer that continues to this day.
For centuries the Eskimos lived on the Arctic ice north of Canada in the winter (not summer) spearing seals through their breathing holes in the ice. The diet of the people and dogs was 100% seal meat and seal fat. The diet was about 80% fat and 20% protein. Their carbohydrate intake was zero, none. They did not have any problem maintaining the level of blood sugar. Dietary carbohydrates (glucose) is not needed for the brain, heart or any other body organ. The body can make glucose from fat and protein. The level of blood sugar is maintained perfectly well naturally.
The pregnant Eskimo woman would give birth to a baby. The mother's milk would be just like the milk of all human mothers, 58% fat, 12% protein and 30% carbohydrates (lactose or milk sugar). As the infant became completely weaned by age 2 the child's diet became 80% fat, 20% protein and zero carbohydrates. This diet grew tough, strong and perfectly healthy children.
