Chick-fil-A Spicy Chicken Sandwich

High histamine

This spicy sandwich is high, mainly from the pickles, with cayenne and peanut oil adding to it.

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

It is a cayenne-spiced breaded chicken breast on a buttered bun with pickles, and a few things drive it up.

  • Pickles — these are fermented cucumbers, and that curing is why they land high in histamine.

  • Cayenne pepper and peanut oil — both sit at a moderate level, so on top of the pickles the sandwich reads high overall.

The chicken and bun are the gentler parts, so the pickles are the first thing to leave off.
