Brazil nuts
Brazil nuts are unfermented and unaged, making them one of the lower-histamine nut options.
Because Brazil nuts aren't fermented, smoked, or heavily processed, they don't go through the steps that typically raise histamine content.
-
Low by nature — most plain, raw or lightly roasted nuts sit on the lower end of the histamine scale, and Brazil nuts are no exception
-
Watch for additives — flavored or seasoned Brazil nuts may include ingredients like vinegar, spices, or preservatives that are more likely to be problematic
Plain, fresh Brazil nuts are generally a comfortable choice compared to many other snack options.
