Is cedar nuts high in histamine liberators?

Watch for

Pine mouth, also called pine nut syndrome, is a taste disturbance rather than an allergic reaction. A constant bitter or metallic taste appears one to two days after eating and lasts around nine days on average, up to about two weeks, then resolves on its own with no lasting effects. / The delay is what fools people. Because symptoms start a day or two later, most of us blame whatever we ate that morning. If a metallic taste sets in, look back two days in your log, not two hours. / The species matters more than the brand. Cases have been traced to nuts of Pinus armandii, a cheaper white pine that gets blended into generic commercial pine nut packs. Nuts sold specifically as Siberian cedar nuts are bought precisely to sidestep that lottery. / Do not confuse rancidity with pine mouth. These are very high-fat seeds that go rancid quickly, and rancid nuts taste bitter in your mouth immediately and smell of old paint. Pine mouth arrives later and makes other food taste wrong. / Nickel is graded borderline, as it is for nuts generally, and a small serve of roughly 14 g keeps the mild FODMAP load low.
