Histamine is not destroyed by normal cooking temperatures, so even properly cooked fish can still result in poisoning. [9] Histamine is the main natural chemical responsible for true allergic reactions, so the symptoms produced are almost identical to a food allergy. [10] [11] Rarely, cheese may be involved. [3]
Histamine intolerance is a presumed set of adverse reactions (such as flush, itching, rhinitis, etc.) to ingested histamine in food. The mainstream theory accepts that there may exist adverse reactions to ingested histamine, but does not recognize histamine intolerance as a separate medical condition that can be diagnosed. [1]
Although histamine is small compared to other biological molecules (containing only 17 atoms), it plays an important role in the body. It is known to be involved in 23 different physiological functions. Histamine is known to be involved in many physiological functions because of its chemical properties that allow it to be versatile in binding.
“Histamine is released in the body and enters the gastrointestinal tract, which can cause gas, bloating, nausea, stomach pains and diarrhea.” He notes specific foods that can make seasonal ...
Histamine is a weak base (a compound able to react with a hydrogen ion to form an acid) that can link with acid groups within the granules of the mast cells. [8] The mechanism of the displacement theory. The crux of this theory lies in the assumption that histamine liberators release histamine by displacing it from cells.
Symptoms are thought to be the result of histamine being released by mast cells on the surface of the skin. Despite the lack of antigens, histamine causes the skin to swell in affected areas. If the membrane that surrounds the mast cells is too weak, it will easily and rapidly break down under physical pressure, which then causes an allergic ...
Degranulation in mast cells is part of an inflammatory response, and substances such as histamine are released. Granules from mast cells mediate processes such as "vasodilation, vascular homeostasis, innate and adaptive immune responses, angiogenesis, and venom detoxification."
Histamine release in the brain triggers secondary release of excitatory neurotransmitters such as glutamate and acetylcholine via stimulation of H 1 receptors in the cerebral cortex. Consequently, unlike the H 1 -antihistamines which are sedating, H 3 -antihistamines have stimulant and cognition-modulating effects.
