Is Subway Sriracha Sauce High in Histamine?

Subway Sriracha Sauce

Moderate histamine

Subway's Sriracha Sauce is moderate in histamine, from its chili pepper, vinegar, and soybean oil.

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 spicy sauce made from chili pepper, vinegar, garlic, sugar, and a bit of soybean oil and egg yolk.

Chili and vinegar together — the chili pepper and the vinegar both sit at moderate, which keeps the whole sauce in the middle range.
Soybean oil rounds it out — the soybean oil base is also moderate, so nothing here is high but a few things land at the same moderate level.

If you want to keep things lower, a plain oil dressing is the milder pick.
