What are Histamines?
Histamines are chemicals produced during any allergic reaction. During this reaction, some of your white blood cells (mast cells) release histamines during the inflammatory immune response. This is all part of a healthy, balanced immune system.
What is Histamine Intolerance?
Though there are foods that naturally contain or trigger histamine release within the body, a histamine intolerance actually occurs when there's a histamine overload from a deficiency or dysfunction of enzymes that break down histamines. Without these enzymes, the body cannot effectively get rid of the excess histamines.
NOTE: Histamine intolerance is NOT the same as a food allergy.
What are the Symptoms of Histamine Intolerance?
Histamine intolerance is rare. Basically, it is an allergic reaction without the allergen. It is considered a pseudoallergy. The symptoms of histamine intolerance and allergic reactions are similar. Symptoms include the following:
What is the Root Cause of Histamine Intolerance?
The root cause of a histamine intolerance varies from leaky gut to methylation impairments or disorders like mastocytosis (leads to many mast cells). Medications that block diamine oxidase (DAO) function or prevent production are also a cause. For most people, leaky gut is the culprit.
Can Histamine Intolerance be Healed?
If the histamine intolerance is caused by a leaky gut, healing can take place. The first step is to avoid foods that that lead to a leaky gut (i.e., junk food, gluten, sugar, and starchy carbs). Also, healing any nutrient deficiencies is a must. The best diet for healing a leaky gut is the bone broth diet as it is an elimination diet. Bone broth is very healing to the gut. Once progress has been made, foods that are low in properties (i.e., lectins, oxalates) are reintroduced one at a time for a two week period each.
Are there Supplements that Can Boost Healing?
To relieve histamine intolerance, healing of a leaky gut must take place. Following are some supplements that can help.
How Long Does it Take to Heal Histamine Intolerance?
Healing time for histamine intolerance depends on a person's body and how bad the histamine issue is. For some, it may take a few weeks or months. Others may need a few years. You can always ask your practitioner to run labs on a regular basis to check your histamine/DAO ratio.
Remember that Histamine Intolerance is Rare
Just remember that histamine intolerance is rare and is NOT the same as a food allergy. Just because a person has a specific food allergy doesn't mean s/he has a histamine intolerance.
