Does soy lecithin count as a soy allergen?
In short: Soy lecithin is made from soybeans, so labels in the US and EU declare it as soy. It contains very little protein, and some people with a soy allergy are told they can tolerate it, but that is a decision to make with your allergist. Lecithin or E322 without a source can also come from sunflower or egg, so read the whole label.
Lecithin is an emulsifier that keeps fat and water mixed. It is common in chocolate, biscuits and margarine.
What the label says
When lecithin comes from soy, labels in the US and EU have to make that clear, for example "soy lecithin" or "lecithin (soya)". If the source is an allergen such as egg, it also has to be declared.
What it means for a soy allergy
Soy lecithin has very little protein, but very little is not none. Whether you need to avoid it is a question for your allergist. Do not decide based on a general article. See also hidden soy names.
