Chicken stock
Chicken stock is widely reported as high in histamine — meat freshness matters most, and histamine can continue to build as stock cools and sits.
The process that makes chicken stock rich and flavorful is also associated with higher histamine levels.
-
Freshness of the chicken matters most — histamine is produced by bacterial activity on proteins; using the freshest possible chicken reduces the starting histamine load, since cooking temperatures halt bacterial activity but do not destroy histamine that has already formed
-
Storage after cooking matters too — histamine can continue to build as stock cools and sits in the fridge due to renewed bacterial activity, so day-old stock tends to have more than freshly made stock that's been cooled quickly and used promptly
Using freshly made stock and consuming it the same day, or freezing it right away, can help keep histamine levels lower.
