Toast
Toast made from standard white or wheat bread is moderate — the toasting itself is fine, but bread additives and preservatives can add up.
Plain toasted bread doesn't accumulate histamine through the toasting process, but what's in the bread matters.
-
Preservatives and additives — commercial sandwich bread often contains vinegar or other additives that may contribute to histamine load even before you add toppings; vinegar in particular appears on many histamine intolerance avoidance lists.
-
Toppings shift the equation — toast topped with jam, aged cheese, or processed spreads can quickly turn a moderate food into a higher-histamine meal.
Simply made bread — short ingredient list, no added vinegar — tends to be the better starting point for toast.
