Soybean lecithin
Soybean lecithin is a heavily processed soy derivative — generally considered lower histamine concern, but soy sensitivity can still play a role.
Soybean lecithin is extracted and purified to the point where it's quite different from whole soybeans or fermented soy products.
-
Processing removes most concern — unlike fermented soy foods such as soy sauce or miso, lecithin is a highly refined emulsifier with very little protein or fermented content, placing it lower on most histamine concern lists
-
Soy sensitivity overlap — some people with histamine intolerance also react to soy more broadly; if soy in general is a trigger for you, lecithin may still be worth paying attention to even if the histamine mechanism is less direct
It appears in many processed foods, so it can be easy to consume without noticing it in ingredient lists.
