Walnuts and histamine – everything about the tolerability of these natural powerhouses
Walnuts are extremely nutritious and offer a multitude of health benefits. For centuries, they have been an important part of the human diet and are often even referred to as a superfood due to their unique nutrient composition. But are they also suitable for a low-histamine diet or are they considered more of a high-histamine food? You will find out that and much more in the blog article below.
Walnuts: Origin, Appearance & Taste
The walnut tree was originally native to Northern India and reached Europe via the Romans. Especially in rural areas, these nutritious nuts were invaluable during the winter months, as few other foods were available at that time. The oil extracted from the nuts was used both for eating and for oil lamps. As is still the case today, liqueurs, ratafias, and flavored wines were prepared from the covering of the shell. The shell was then used to make dye for furniture makers and dyers.
Today, leading cultivation areas include the USA and Turkey, as well as China, Romania, Iran, France, and the Balkan states. The whitish-yellow walnut is an irregularly shaped, wrinkled kernel that consists of two halves that are connected by a third, while the remaining part is separated by a membrane. The kernel is covered by a light- to dark-yellow, thin skin and enclosed by a hard, arched shell that is round to oval and, in some varieties, very woody. The shell, in turn, is enclosed by a fleshy, sticky, green outer husk.
In terms of taste, walnuts are typically nutty, slightly sweet, and at the same time somewhat bitter.

Walnuts and Histamine: How Tolerable Are These Nutrient Bombs?
According to the SIGHI list, walnuts are classified as a 3 and are considered histamine liberators. Therefore, they are unsuitable for a low-histamine diet. However, there are also some nuts or seeds that are suitable for a low-histamine diet, such as Brazil nuts, macadamia nuts, pistachios, or pumpkin seeds.
Walnuts are generally unsuitable for the following diets:
· low-histamine diet
· low-salicylate diet
· low-nickel diet
Walnuts are suitable for the following diets:
· gluten-free diet
· lactose-free diet
· low-fructose diet
· low-sorbitol diet
Purchasing and Storing Walnuts
When buying walnuts and walnut kernels, you should pay particular attention to the quality. The shell should be free of cracks or damage and the kernels should not show any atypical discoloration or odors. If you want to be on the safe side, it is recommended to buy walnuts from an organic retailer.
Due to the high nut oil content, walnuts should ideally be stored in a dark and cool place, but not in the refrigerator. For packaged nuts, you can easily follow the best-before date, and for loose walnuts, it is recommended to ask the retailer for the maximum recommended storage duration. To ensure even ventilation, it is best to hang the nuts in a small bag.
