McDonald's Premium Crispy Chicken Classic Sandwich

High histamine

This chicken sandwich runs high from the tomato slice and mayonnaise.

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 Histamine Liberator

A Premium Crispy Chicken Classic pairs a breaded crispy chicken fillet with tomato, mayonnaise dressing, and leaf lettuce on a bakery style bun, and it lands high.

  • Tomato and mayo lead — the tomato slice is a classic histamine liberator, and the mayonnaise dressing is high, so together they set the level.

  • The fillet and base are milder — the breaded chicken fillet sits at moderate from its wheat coating, and the fresh bun and lettuce are the gentlest parts.

Dropping the tomato and mayo brings this down.
