The Claim

Consumption of dried whole fish (ammassak) including intestinal contents during an Indigenous Arctic diet is associated with the transient appearance of food-associated microbial taxa such as Photobacterium in the human gut.

In plain English

Eating dried whole fish with intestines as part of a traditional Arctic diet is linked to the temporary presence of specific bacteria, like Photobacterium, in the human gut.

See the scientific wording

The consumption of dried whole fish (ammassak) including intestinal contents during an Indigenous Arctic diet is associated with the transient appearance of food-associated microbial taxa such as Photobacterium in the human gut, suggesting dietary exposure to live microbes from traditional foods may contribute to gut microbiota dynamics.

Why this might work

When a person eats dried whole fish including its intestines, live bacteria from the fish's gut enter the human digestive tract. These bacteria pass through the gut without settling permanently, briefly showing up in stool samples. At the same time, the high protein and fat content of the diet starves bacteria that need plant fibers and lets other bacteria that thrive on meat and fat grow more. This combination of new microbes arriving and existing ones changing in number shifts the overall mix of gut bacteria temporarily.

  1. Study: Dietary transition to an Indigenous Greenlandic diet induces instant shifts in gut microbiota composition – a pilot intervention study

    Eating dried whole fish, including its insides, temporarily introduced new bacteria into the person’s gut that came from the fish itself — these bacteria showed up while eating the fish but disappeared afterward, just like the claim says.
