Is Tim Hortons Sausage Bagel Breakfast Sandwich High in Histamine?

Tim Hortons Sausage Bagel Breakfast Sandwich

High histamine

This sandwich is high in histamine, from autolyzed yeast, lemon powder, and the bagel.

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.

Gluten Dairy Histamine Liberator

This is a sausage patty with egg and fresh dairy on a bagel made from wheat flour, rye, and malted barley.

Autolyzed yeast and lemon powder lead — autolyzed yeast runs high, and lemon powder is a citrus-based histamine liberator, so both push the level up.
The bagel adds to it — enriched wheat flour, rye flour, malted barley, and yeast all sit at moderate, so the bread base is not neutral here.

Because the seasoning and the bagel both drive this up, a plainer egg option from the same menu would sit lower.
