Can You Eat Pistachios If You Have Nut Allergy?

This is where caution is essential. 

If you have tree-nut allergy, do not assume pistachios are safe because they are technically seeds. Pistachios are recognised as tree nuts in allergy guidance, and exposure can cause allergic reaction in suscepticle people. 

Pistachios are also closely related to cashew, so people people with certain tree-nut allergies may need specific medical advice about both. 

If you are buying packaged food, check the allergen information every time. If you’re eating at a restaurant, ask about ingredients and possible cross-contact rather than assuming a dish is safe. 

When an allergy is involved, the botanical definition isn’t the useful definition.
