Is Subway Egg Omelet Patty High in Histamine?

Subway Egg Omelet Patty

Moderate histamine

Subway's egg omelet patty is moderate in histamine, mainly from the 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 folded egg patty made from egg white and yolk with a little oil, and it lands at moderate.

Soybean oil is the driver — the soybean oil here is moderate and also carries a liberator tag, which is what keeps this from being a clean low choice.
The eggs themselves are milder — the egg white and yolk are not the concern, so it is the oil and small extras nudging the level.

If you want to keep breakfast lower, plainly cooked eggs without the added oil tend to be gentler.
