Orange

Oranges don't need to be high in histamine to cause issues — they're well-known for triggering the body to release its own stored histamine.

• Histamine liberator — citrus fruits like oranges are among the most commonly cited triggers in histamine intolerance literature, regardless of histamine content

• Juice amplifies the effect — a glass of orange juice concentrates the effect of many oranges at once, so it tends to be harder to tolerate than eating a single orange

If you're missing citrus flavor, some people find mango or fresh melon a gentler swap worth trying.
