The Inuit diet: raw food and nutritional adaptation

The Inuit of the Arctic Circle are the most cited example in ancestral nutrition discussions; and the most misrepresented. The reality is more nuanced and more interesting than either the celebratory or dismissive versions.

What traditional Inuit actually ate

Seal (meat, fat/blubber, organs, blood), whale (beluga, narwhal), walrus, caribou, Arctic char, cod, and various birds. The critical point: a significant portion was consumed raw or fermented (igunaq). Vilhjalmur Stefansson, who lived with Inuit communities between 1906 and 1918, documented that they ate liver, kidneys and other organs raw immediately after a kill.

The scurvy-prevention paradox

The Inuit diet contains almost no vitamin C from plant sources. The solution: raw meat and organs. Fresh raw meat contains small amounts of vitamin C (roughly 1–2 mg per 100 g in muscle; higher in organs). Stefansson himself demonstrated that eating only fresh raw and cooked meat for one year, under medical observation at Bellevue Hospital in 1928, prevented scurvy. Cooking destroys the vitamin C that prevents it.

For the traditional Inuit, eating raw was not a preference. It was the architecture that kept the diet survivable.

What genomic research shows

Inuit populations carry unique genetic variants (FADS1, FADS2, ELOVL2) that alter fatty acid metabolism, optimized for high dietary omega-3 from marine sources. This is evidence of genuine genomic adaptation to diet over generations.

The real lesson

There is no single human diet. There is a single human refusal of industrial food.

The Inuit teach plurality, not a recipe: and they teach that how a food is prepared can matter as much as which food it is.
