Is Texas Roadhouse Mango Syrup High in Histamine?

Texas Roadhouse Mango Syrup

Moderate histamine

This mango syrup is moderate in histamine, mainly from the lemon juice concentrate blended in.

Most of this is cooked to order, which is the best case for histamine. Even so, a restaurant kitchen preps ahead and holds things warm through a service, so freshness varies more than it would at home. The rating above comes from the chain's published ingredients. If a dish is borderline for you, asking how it is prepared tells you more than the menu does.

Histamine Liberator

This is a simple sweet syrup of cane sugar, natural flavor, and lemon juice concentrate.

Lemon juice concentrate — lemon is a classic histamine liberator, and here it is the ingredient nudging the syrup up to moderate.
The rest is mild — cane sugar and natural flavor sit low, so the citrus concentrate is really the one thing setting the tone. That keeps it at moderate rather than high.

If you want a drink built on this, know the lemon is what carries it, so a citrus-free sweetener is gentler.
