Histamine sensitivity

Fermented foods are high in histamine. This is a neurotransmitter and is known for causing an immediate inflammatory response in our immune system. It causes the blood vessels to dilate so that white blood cells can find and attack the infection or problem – which is, of course, what they are supposed to do. However, if you cannot break down histamine properly, you might develop an intolerance. Because histamine travels in the bloodstream it can cause symptoms anywhere in the body. Common histamine intolerance symptoms are migraines, sleep problems, high blood pressure, hives, itchiness, congestion and abdominal pain Histamine is broken down by enzymes but histamine-sensitive people are often lacking in these enzymes. This can sometimes be for genetic reasons but more often not; there can be many reasons as to why these enzymes are lacking and it is not always easy to find out why. Non-genetic reasons for histamine sensitivity could be a leaky gut, intestinal bleeding and small-intestine bacterial overgrowth (SIBO), hormonal imbalances and allergies. Histamine-sensitive people should avoid ferments. If you suspect you have a histamine imbalance, do consult a health professional.
