Is Subway Hot Honey Sauce High in Histamine?

Subway Hot Honey Sauce

High histamine

Subway's Hot Honey Sauce is high in histamine because of the aged red peppers in it.

Food here is usually assembled to order from components that were prepped earlier in the day, so it tends to be fresher than a drive-through and less fresh than cooking at home. Histamine builds up as protein foods sit, so how long the chicken or beef has been in the warmer matters as much as what is in the bowl. Treat the rating above as a starting point.

Histamine Liberator

This is a sweet-hot sauce built from sugar, honey, vinegar, aged red peppers, and a little garlic and onion.

Aged red peppers lead — the aging step is what drives histamine up here, and it makes this sauce high on its own.
The rest is milder — the honey, sugar, and vinegar sit lower, so the aged peppers are really what set the level.

If you want some flavor without the aged element, a plain oil-based option is gentler.
