Yes, hazelnuts are low histamine. They’re also known as filberts in Europe, and they’re a great source of copper, vitamin E, and manganese. While some particularly sensitive people may struggle with hazelnuts due to their content of other biogenic amines, most people will tolerate this tree nut just fine. You can enjoy hazelnuts on their own as a snack, or ground into a butter for gluten-free crackers, or even chopped up to sprinkle on your cereal. However, if you’ve ever reacted to a nut or seed in the past, it’s best to be cautious in reintroducing hazelnuts.
