jbsusie - Any food that produces a sensation that resembles anxiety or panic - jitteriness, racing heart, sweating, butterflies in the stomach, chest tightness, etc. could potentially trigger an attack because people with panic disorder are often misinterpreting bodily cues and hypersensitive to the sensations associated with panic. So if a food makes your daughter feel like she's having a panic attack that may raise her anxiety to very high levels. Whether this will actually trigger an attack is hard to say but she is likely to feel very uncomfortable and scared.
