Is Panera Bread Tropical Green Smoothie Base High in Histamine?

Panera Bread Tropical Green Smoothie Base

High histamine

This green smoothie base is high in histamine, driven by spinach and lemon juice concentrate.

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

It is a tropical fruit and greens blend with mango, guava, pineapple, passion fruit, grape, spinach, and spirulina.

Spinach and lemon juice concentrate — spinach and citrus are both classic histamine liberators, and they are the highest ingredients here, setting the rating.
The fruit concentrates — mango, white grape, pineapple, and passion fruit each land moderate, so even the fruit side runs on the higher end.

With so many higher ingredients built into the base, there is no clean way to bring this one down; a plain black tea is a lower option instead.
