Is Tim Hortons Twelve Grain Bagel High in Histamine?

Tim Hortons Twelve Grain Bagel

Moderate histamine

This twelve grain bagel is moderate, driven by its wheat and barley flours, yeast, and molasses.

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

This is a yeasted multigrain bagel made from enriched wheat flour, a grain mix, wheat bran, flaxseed, and malted barley flour.

The flour blend — the enriched wheat flour, wheat bran, and malted barley flour all sit at moderate, and together they set the bagel's level.
Yeast and molasses — the yeast and the molasses are also both moderate, which keeps this in the middle range rather than low.

A plain fresh wheat roll without the barley flour and molasses would tend to sit lower.
