Sonic Pork Tenderloin Fritter

High histamine

This breaded pork fritter runs high, mostly from the torula yeast and buttermilk blend in the coating.

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

A Sonic Pork Tenderloin Fritter is a pork loin cutlet in a seasoned wheat-flour batter, and it lands high.

  • Torula yeast and buttermilk blend — both are high, and they sit right in the breading and seasoning that coats the whole fritter, so they set the level.

  • The wheat coating — the enriched wheat flour and wheat starch in the batter are moderate, which matters for anyone also watching gluten. The pork itself is the mildest part.

The breading is what carries the histamine here, so a plainer option is the smarter pick.
