Is Taco Bell Flour Tortilla High in Histamine?

Taco Bell Flour Tortilla

Moderate histamine

The flour tortilla is moderate from its wheat and barley flour plus soybean oil.

Fast food is cooked in batches and held warm rather than made when you order it, so it is rarely as fresh as something cooked at home. That matters here because histamine builds up as protein foods sit, which means the same item can affect you differently depending on how long it waited.

Gluten

This is a soft wheat tortilla made with malted barley flour and oils, and it comes in at moderate.

Wheat and malted barley flour — the malted barley flour and wheat flour both carry a moderate level here, which is the main reason the tortilla sits where it does.
Soybean oil adds to it — the soybean oil in the dough is also moderate, so between the flours and the oil, the whole tortilla stays at moderate.

For a lower base on the same menu, the white corn shell is the cleaner pick.
