Is Sonic Liquid Margarine High in Histamine?

Sonic Liquid Margarine

Moderate histamine

Liquid margarine is moderate in histamine, driven by its soybean oil base.

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.

This is a soybean oil margarine with salt, emulsifiers, flavor, and color.

The margarine and its soybean oil — both the liquid margarine and its liquid and hydrogenated soybean oil sit at a moderate level, which sets the rating.
The extras are mild — the salt, lecithin, and flavorings are there for texture and taste and are not the reason for the level; the oil base is.

Asking for items made with plain butter instead keeps things lower where that is an option.
