accountIn the early 19th century, Arctic explorers and whalers began trading with the Inuit, introducing pilot biscuits, flour, sugar, coffee, tobacco, and salt into the traditional indigenous diet.
claimIt is hypothesized that several millennia of low exposure to high carbohydrate loads caused the Inuit population to either increase the sensitivity of the GLUT1 transporter or down-regulate its expression, which may explain the lack of scurvy in the Inuit pre-contact with Westerners and their increased susceptibility to diabetes, alcoholism, and scurvy post-contact as described by Price.
claimThe Inuit in northern Quebec were living on a diet similar to the mixed and processed diets at the time physicians identified neonatal hypertyrosinemia in 1975.
claimThe Inuit traditionally select animal parts with high Ascorbic Acid (AA) concentrations for consumption.
measurementThe transition to processed, carbohydrate-rich foods among Inuit populations resulted in a reduction of traditional food intake by approximately 33% of total intake, as reported by Kuhnlein, Soueida, and Receveur (1995).
claimThe traditional Inuit diet provided moderate levels of vitamin C through the consumption of liver, adrenal glands of caribou, the blubber and skin of whales, the liver, brain, and fat of seals, berries, and sorrel grass (also known as scurvy grass).
accountThe Inuit historically consumed the fattiest parts of animals to prevent 'rabbit starvation' and fed the leanest meats, such as muscle, to their dogs, as documented by Fediuk (2002).
claimTraditional pre-contact Inuit populations did not have a history of epidemic vitamin deficiency diseases such as pellagra or beri-beri, according to research by Draper (1977) and Sandler (1951).
accountThe Canadian Federal Family Allowance payments, which began in 1945, provided trade goods to all Inuit families with children under the age of 16, leading to changes in the traditional Inuit diet.
measurementThe macronutrient ratio of the traditional Inuit diet was approximately 56% protein, 43% fat, and 1% carbohydrate, indicating that pre-contact Inuit people were in ketosis due to very low carbohydrate intake.
claimThe traditional Inuit diet includes the consumption of animal adrenal glands and brains, which are sources of fat and vitamin C.
perspectiveThe authors suggest that Inuit and other indigenous diets, which are characterized by lower levels of carbohydrate and higher levels of fat, contain wisdom that could be realized to improve health outcomes.
claimThe need to fortify processed foods arose in Inuit communities to prevent scurvy and other nutritional deficiency diseases following the reduction of traditional food intake.

measurementInuit and other Arctic groups traditionally derived up to 99 percent of their calories from seals, narwhals, and fish.
claimTraditional human diets vary significantly across cultures, including the vegetarian regimen of India’s Jains, the meat-intensive fare of the Inuit, the fish-heavy diet of Malaysia’s Bajau people, and the insect-based protein diet of the Nochmani of the Nicobar Islands.
claimThe Inuit of Greenland survived for generations on a diet consisting almost entirely of meat due to the harsh landscape.
