Collard greens

Low histamine

Collard greens are a low-histamine leafy green with no known histamine-releasing or blocking properties.

Collard greens are simply a fresh vegetable — no fermentation, no aging, no known compounds that interfere with histamine processing.

  • Why they're well-tolerated — they don't contain meaningful histamine, and unlike some foods, they don't prompt your body to release its own stored histamine either

  • Freshness still matters — like any leafy green, they're best used soon after purchase; wilted or older greens can develop slightly higher biogenic amine levels

They're a solid, nutrient-dense green that tends to be easy to work with on a low-histamine diet.
