What to know about lemon

Lemon is a classic histamine liberator: it is low in histamine itself, yet it prompts your mast cells to release their own histamine, which is why citrus can bring on hives, itching, flushing or a runny nose even though the fruit is not a high-histamine food. That catches people out on a low-histamine diet, because the usual trick of choosing fresh, unaged foods does not neutralise a liberator. Lemon is also moderately high in salicylates and a moderate FODMAP by volume, so a big squeeze adds to the load, but the liberator effect is the story worth watching.

Watch for

  • Strong histamine liberator, so it can cause hives, itching, flushing or a stuffy nose even though lemon is low in histamine itself
  • Being low-histamine does not make it safe if you are liberator-sensitive: the reaction comes from your own released histamine, not from the fruit
  • Moderate salicylate, an extra trigger if you also react to aspirin or salicylate-rich foods
  • A large volume of juice is a moderate FODMAP load, so a small squeeze sits better than a whole glass of lemonade
