Is pistachio milk safe for people with nut allergies?

Quick answer

No. Pistachio milk is made from pistachios, a tree nut, so it is not safe for people with a pistachio or tree nut allergy. Pistachio is on the FDA tree nut list and is closely related to cashew, so people with a cashew allergy should also be careful. Ask your allergist.

Is pistachio milk safe for nut allergies?

No. Pistachio milk is made from ground pistachios, which are a tree nut. Straining a nut milk does not make it allergen-free, and brands label it as a tree nut product. This is general information, not medical advice. Follow your allergist’s plan.

Why is it a risk?

  • It is on the labeling list. FARE reports that the FDA’s list of 12 tree nuts requiring allergen labeling includes pistachio.
  • Cross-reactivity. The AAAAI says there is probably an increased risk of clinical cross-reactivity between cashew and pistachio, which share similar proteins. It also notes that cashew cross-reacts with hazelnut, walnut and others, and that these patterns make clinical conclusions difficult. If you are allergic to cashew, discuss pistachio with your allergist rather than trying it.
  • Cross-contact. Even a nut-free milk can pick up traces in a factory that also handles nuts.

Which milks are alternatives?

Milk Tree nut? Note
Pistachio, almond, cashew, hazelnut, macadamia Yes Avoid with tree nut allergy
Oat, rice No Check for cross-contact; oat is not gluten-free unless labeled
Soy, pea No Soy and other legume allergies are separate issues
Hemp, flax No Seed-based; check the label
Coconut Not for US labeling Still a recognized allergen

How do you read the label?

  • Check the Contains statement and the ingredient list.
  • Look for may contain tree nuts or shared-equipment warnings.
  • Check again whenever you change brand or carton, because recipes change.

If anyone in your household has a severe allergy, ask your allergist which milks are suitable and keep emergency medicine available as advised.

People also ask

Can people with tree nut allergies drink pistachio milk?

No, unless an allergist says so. Pistachio is a tree nut.

Is pistachio related to cashew?

Yes, they are closely related, and the AAAAI says studies have shown cross-reactivity between them. Ask your allergist.

What milk is safe for a nut allergy?

Oat, soy, pea, rice, hemp and flax milks are not tree nut milks, but check the label for cross-contact.

General information only, not medical advice. If you have a health condition or are pregnant, ask your doctor before changing what you drink.
