Water spinach
Water spinach is generally low in histamine — a better-tolerated alternative to regular spinach, which is often flagged in histamine intolerance.
Water spinach (also called morning glory or kangkong) is a leafy green common in Southeast Asian cooking that tends to sit lower on the histamine scale than regular spinach.

Not the same as spinach — regular spinach is widely flagged in histamine intolerance literature as potentially problematic, though the exact mechanism is debated; water spinach is a different plant and doesn't appear to share the same concern

Freshness still matters — like any leafy green, water spinach is best eaten fresh; as it ages or wilts, natural breakdown may gradually raise histamine content
A good leafy green option for those who react to regular spinach.
