NOTE: If you have a nut allergy or have shown to have a reaction to almonds or other nuts, you should avoid them and consult with a doctor to determine if you are allergic to them or not. 

Are Pistachios High in Histamine?

While most nuts aren’t naturally high in histamine, they do contain histidine. So while a pistachio (depending on spices added if you buy them packaged) isn’t necessarily high in histamine, they can cause a similar reaction to those sensitive to histamine. If you haven’t tried pistachios before and are trying them for the first time, I’d recommend asking a doctor and taking an allergy test beforehand. If you have eaten pistachios before and aren’t sure if they caused a slight reaction, then eliminating them and reintroducing them into your diet can help determine if that’s what caused the reaction. 

The tips listed above for elimination and reintroduction are to be done AFTER consulting a doctor or physician. 

Are Nuts Naturally High in Histamine?

Some examples of nuts to avoid are peanuts, cashews, almonds and pistachios.

Are Pistachios Low FODMAP?

Pistachios are sadly high histamine do to them containing GOS and fructans. Unlike nuts and their histamine relation, there are some nuts that are low FODMAP such as peanuts and pine nuts.

Summary

Sadly pistachios contain histidine, while not histamine, it can cause a similar reaction to those sensitive to histamine. Therefore, pistachios and most nuts should be avoided if you have a histamine intolerance.
