Is McDonald's Quarter Pounder Deluxe High in Histamine?

McDonald's Quarter Pounder Deluxe

High histamine

This burger runs high from the tomato, mayonnaise, and pickles.

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.

A Quarter Pounder Deluxe builds a beef patty, tomato slice, mayonnaise dressing, American cheese, crinkle cut pickles, red onions, leaf lettuce, and mustard on a bakery style bun, and it lands high.

Tomato, mayo, and pickles lead — the tomato is a classic histamine liberator, the mayonnaise dressing is high, and the crinkle cut pickles are high from their brine cure.
Beef, cheese, and mustard add to it — the patty, the processed American cheese, and the mustard sit at moderate, while the fresh bun, lettuce, and onions are the mildest parts.

Dropping the high toppings brings this down.
