Tomato soup
Tomatoes are potent histamine liberators, and cream or dairy additions may make it harder for your body to process histamine.
Tomato soup is essentially a concentrated dose of one of the most well-known histamine-triggering foods.
-
Tomatoes as liberators — tomatoes don't just contain histamine, they also prompt the body to release its own stored histamine, which is why even small amounts can have an outsized effect
-
Dairy additions — many tomato soups include cream or milk, and dairy is commonly reported to compound histamine sensitivity, though the exact reason isn't fully understood
Homemade versions using less tomato concentration and no dairy may be easier on the system than canned or carton soups.
