Ice cream may be low histamine. It’s more difficult to give a straightforward answer here, because even a traditional dairy-based ice cream can easily have over ten ingredients. Most ice creams are not low histamine due to their inflammatory sugar content, flavorings, and preservatives. But there are some low-sugar ice creams out there that some people can tolerate, and a lot of non-dairy ice creams that are both low histamine and better for you than a traditional scoop. Most of these alternatives are either oat- or coconut-based, and a few brands even have flavored low histamine ice creams.
