Histamine Tracker
Spinach
Spinach contains naturally occurring histamine and also acts as a histamine liberator, making it one of the more reactive leafy greens.
Spinach stands out from most leafy greens because it contains histamine directly and may also trigger the body to release more from its own stores.
-
Natural histamine content — spinach has measurable histamine levels even when fresh, which is unusual for a leafy vegetable and sets it apart from options like lettuce or kale
-
Cooking effect — cooking spinach doesn't reduce its histamine content, and wilted or older spinach tends to have more than very fresh leaves
Lettuce, arugula, or kale are often better-tolerated alternatives if you're looking for leafy greens.
