This sounds like a possible case of the nocebo effect: Someone experiences symptoms based on a belief that an ingredient is bad for them. When they consume the same thing without the belief that the ingredient is present, the effects are absent even though the ingredient is present. This happens with people who believe they have WiFi sensitivity disorders, too. If you put them next to a WiFi router with blinking lights they will experience the pain of their condition. If you turn off the lights on the router but leave the WiFi transmitting, they stop feeling the effects.
