Best Histamine Blockers for Allergies 2022

Histamine is a significant chemical that is involved in numerous body functions. It stimulates gastric acid secretion, contributes to inflammation, dilates blood vessels, etc.

However, too much histamine can be problematic, causing histamine sensitivity or intolerance, digestive issues, allergies, and more. Individual histamine sensitivity varies, and some people may respond to histamines and other biogenic amines in foods more strongly than others.

Various drugs, such as steroids and allergy injections, can treat allergies, but an antihistamine / histamine blocker is typically the first thing to try.

How Do Histamine Blockers Work?

Histamine blockers are valuable in the management of the more common delayed allergic response and in the definitive management of the acute allergic reaction (administered after epinephrine has resolved the life-threatening phase of the reaction).

Histamine blockers are competitive antagonists of histamine; they do not prevent the release of histamine from cells in response to injury, drugs, or antigens but do prevent histamine’s access to its receptor site on the cell, blocking the response of the effector cell to histamine. Therefore, histamine blockers are more potent in preventing the actions of histamine than in reversing these actions once they occur.

Your body produces the enzyme diamine oxidase (DAO) to breakdown histamine obtained from food. ‌You can develop histamine intolerance, also known as food histaminosis or enteral histaminosis, if you don’t have enough of this enzyme.

According to early studies, DAO supplements may help some histamine intolerance symptoms, such as headaches, skin rashes, and stomach problems,

FAQ

a. What Is Histamine Intolerance?

Histamine intolerance happens when there is an over-accumulation of dietary histamine in the human body. Numerous foods have high histamine levels, and a number of medical conditions and drugs may increase intolerance.

Histamine is a chemical that triggers the production of stomach acid for digestion, communicates with the brain, and is released by the immune system in response to an injury or an allergic reaction.

When the body cannot break down enough of this molecule in the intestines, histamine levels in the blood increase, indicating an intolerance to it.

b. What Food Has the Highest Histamine?

Histamine levels are greater in the following foods:
fermented foods (kefir, yogurt, kombucha, kimchi, sauerkraut, tempe, miso, sourdough bread)
alcohol, wine, beer, liquor
processed meat (hot dogs, ham, sausages, canned meat)
avocados
shellfish
aged cheese
bananas
tomatoes
wheat germ
beans
papaya
chocolate
citrus fruits
nuts, specifically walnuts, cashews and peanuts
food dyes and other additives
