Histamine: Frequently Asked Questions

Histamine is a natural chemical that is released by blood cells and triggers the allergic reaction.

type of food poisoning that results from eating foods (usually fish) containing high levels of histamine.

Histamine is located throughout the entire body. In many instances, it causes inflammation, runny nose, itching, hives, sore throat, coughing, flushing, headache and all those other typical allergy reactions. In the gut, it signals the production of gastric acid. This is why some remedies for acid stomach are really antihistamines. In the brain, it functions like a neurotransmitter. A couple of functions include affecting hunger or feeding, and also sleep/wake cycles (the circadian rhythm). ...

Here is a great site on what foods contain what chemicals. The first link tells about "histamine intolerance" and amine foods: http://users.bigpond.net.au/allergydietitian Notice that many of the foods are often considered "phenol" foods even though they are not high in salicylates or phenols. They are high in amines/histamine. There are also foods that trigger a histamine reaction. ...

One source is when the amino acid histidine looses a carboxyl group. Some bacteria can faciliate this conversion too. So if you have a bacteria overgrowth, it may be using up histidine and converting it to more histamine. Another big source is directly from foods. Some people may have a problem eliminating histamine from their foods and this causes reactions which LOOK LIKE allergies, but are not true IgE mediated allergies. ...

Some people who have trouble converting sulfur to sulfate (PST issue), and who have a sensitivity to certain foods and chemicals because of this, often times develop a high histamine level. My son develops a runny nose as a reaction to this problem. Benadryl helps my son with this, and anything else that lowers histamine would help him, also. I think the Feingold Diet, No-Fenol, or avoiding certain phenolic and high salicylate foods may help the sulfation problem and subsequently lower the high histamine level. ...

The best advice is to try not to use any other medication needed for your sinus/allergy condition. If you still need it for the first few days then use it but try and do without it.

Antihistamine, as the name suggests, nullifies the effect of histamine, which is released as a result of allergic process. However, antihistamine medication does not control the underlying cause of histamine release. So, you feel better only when you take antihistamine.

Methionine is a methyl carrying amino acid + ATP/magnesium = SAMe. SAMe goes throughout the body delivering methyl groups to over 400 different reactions. One way histamine is de-activated (eliminated) is by receiving a methyl group from SAMe. So if there is low methylation, there is low SAMe, and the histamine levels are higher because of the lack of methyl groups to deactivate it. If there is high methylation, there is higher amounts of SAMe, and lots of histamine can be deactivated.
