Nuts
Shell
Brazil nut shell is the hard individual seed coat inside the larger ouriço pod—not food. Commercial crackers aspirate shell grit carefully because fragments are a dental hazard. Sound shells slow oxygen on the high-oil meat compared with warm open bags. Clean shells may become biomass; do not assume they are safe smoking wood. Flavour and selenium live in the kernel only after this armour is gone.

Shell is largely mineral; edible value is minimal except as calcium source when finely prepared.
History
Amazonian peoples harvested Brazil nuts from forest trees long before export markets.
Export trade named and shipped Brazil nuts widely to Europe and North America.
Wild harvest and shelling industries centred in Brazil, Bolivia, and Peru supplied global snack markets.
Forest conservation and fair-trade narratives elevated Brazil nuts as a non-timber rainforest product.
