Histamine Tracker
Cola
Cola combines caffeine and natural extracts — several factors that may affect histamine sensitivity at once.
Cola is a layered drink when it comes to histamine — it's not one single ingredient causing the issue, but several working together.
-
Caffeine as a DAO blocker — caffeine may reduce the activity of DAO, the enzyme that breaks down histamine in your digestive tract, making it harder to clear histamine from food
-
Additives and extracts — natural flavor extracts are often flagged in histamine intolerance literature, though individual responses vary; as with most processed drinks, the full ingredient list is worth checking
Light-colored sodas without caffeine tend to be reported as easier to tolerate by people who are sensitive.
