This week we’re going to have a look at one of our non-food intolerances that we test for in our Intolerance Test: Feathers. More specifically: Goose, Chicken, Duck and Turkey Feathers.
For centuries, humans across the globe have used down feathers for insulation. Russian documents from the 1600s list "bird down" among the goods sold to Dutch merchants, and communities in northern Norway began protecting the nests of eider ducks as early as 1890. Eiders are still "farmed" by people in Iceland, Scandinavia and Siberia.
