Yes, brazil nuts are low histamine. However, it’s important to limit your consumption regardless of brazil nuts’ histamine content, because they’re also notoriously high in selenium. Even though it’s an important trace mineral to have in your diet, a single brazil nut contains more than your daily requirements for selenium, so you shouldn’t have more than two or three per day. If you’ve ever reacted to another nut or seed, you should also take caution in reintroducing brazil nuts.
