Is Jamba Juice Kale Boost High in Histamine?

Jamba Juice Kale Boost

Low histamine

This is just frozen kale blended in, and it is low in histamine.

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 boost is simply frozen kale added to a smoothie for extra greens.

Kale is naturally low — plain frozen kale is not aged, fermented, or a liberator, so it does not push a drink up.
It keeps the rest of the drink honest — as an add-in, kale is a clean way to boost nutrition without adding histamine load.

This is one of the friendlier boosts to build a low-histamine smoothie around.
