Histamine Tracker
Pistachios
Plain pistachios are low in histamine, though some people with sensitivity report reacting to larger amounts of tree nuts.
Pistachios themselves don't contain significant histamine and aren't fermented or aged, which keeps them in the low category.
-
Generally well tolerated — plain, unsalted or lightly salted pistachios are not known to be high in histamine or to trigger the body to release its own
-
Individual responses vary — some people with histamine sensitivity report noticing reactions to tree nuts in general; this isn't well-explained by histamine content alone, so it may come down to personal tolerance
Starting with a small amount and seeing how you feel is a reasonable approach if you're still mapping your own sensitivities.
Track your reactions to pistachios in Histamine Tracker. Log meals and symptoms to spot the patterns that matter for your body.
