Sonic Peach Add-In

Low histamine

Sonic's peach add-in is low in histamine, made from peach puree and sugar.

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.

This is a fruit add-in built from sugar, peach puree concentrate, citric acid, sodium citrate, and pectin.

  • Peach puree — peach is not a histamine driver, so the fruit base here keeps the add-in at a low level.

  • The rest is milder — the sugar, sodium citrate, and pectin are for sweetness and texture and do not push the level up.

This is a solid fruit-flavored add-in when you want something low-key.
