Is Culver's Mayonnaise Packet High in Histamine?

Culver's Mayonnaise Packet

High histamine

High in histamine, driven by the mustard flour and lemon juice concentrate in the packet.

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.

Histamine Liberator

This packet is a seasoned mayonnaise made from soybean oil, vinegar, egg yolks, mustard flour, and lemon juice concentrate.

Mustard flour and lemon juice concentrate — the mustard runs high, and the lemon is a classic histamine liberator, so together they set the level here.
The mayo base and soybean oil — these sit at moderate, so the packet is elevated beyond just the spread itself.

A plain fat like butter is a much gentler choice than this seasoned packet.
