Histamine is naturally produced in our bodies to respond to infections, viruses or allergic reactions (such as pollen). Certain environmental factors can also block the body’s histamine-degrading enzymes from working effectively, causing a histamine overload.

Some food and drink contain high amounts of histamine. Once consumed, these foods and drinks increase the overall amount of histamine in the body. Some food and drink don’t necessarily have high amounts of histamine, but are capable of encouraging your body to release more histamine, acting as liberators.
