Histamine Intolerance: Could This Be Another Reason Why You Are Sick?
Symptoms commonly experienced with histamine intolerance:
Histamine and Eczema
In addition to the symptoms listed above, excess histamine can make some existing conditions worse. Eczema is an example. Eczema is an inflammatory condition in the skin, sometimes called atopic (allergic) dermatitis. When high histamine foods are consumed, people with less than efficient histamine tolerance may experience an increase in the severity of their eczema.
Causes of Histamine Intolerance
- Disbiosis, Small Intestinal Bacterial overgrowth (SIBO) or leaky gut syndrome is a common cause of increased histamine in the system.
- Allergies, GI bleeding (Ulcers, Crohn’s,).
- Histamine- rich foods such (see list below) from fermented alcohol, wine, beer, and champagne.
- Food sensitivities are also linked to histamine intolerance. Genetic mutations or SNP’s can prevent the break down of histamine as well.
- Medications such as Diuretics, Synthetic hormones, Statins can induce a vitamin deficiency that block the functioning of the DAO and HNMT gene. (You can read more about this below)
Nutritional deficiencies include Iron, Copper, Riboflavin (B2), B12, B6, and vitamin C. Deficiency in these vitamins can block the functioning of the DAO or HNMT gene.
Foods High in Histamine:
- Processed meats such as deli meat, hot dogs, bratwurst, pepperoni, salami, bacon
- Vinegar rich foods such as pickles, olives, mayonnaise, relishes, dressings, ketchup
- Fermented foods such as sauerkraut, yogurt, soy sauce, kombucha, kefir, pickled vegetables- Yes you read that correctly- The very foods you might be eating because of the gut healing properties may be making you worse.
- Soured food such as sour cream, sourdough, buttermilk
- Dried fruit such as raisins, apricots, cranberries, dates
- Citrus fruits
- Aged cheese
- Raw and roasted nuts: peanuts, cashews, walnuts
Foods that release Histamine:
- -Fruits: banana, papaya, pineapple, strawberries
- -Wheat germ
- -Cow’s milk
How to Break down Histamine
DAO deficiency can be caused by:
- -Inflammation caused by autoimmune disease such as Crohn’s, ulcerative colitis, IBS.
–Foods that inhibit histamine break down by blocking the DAO enzyme. Some of these foods include: alcohol, energy drinks, black tea, green tea, and mate tea
- –Leaky Gut
- NSAIDs (ibuprofen, aspirin)
- Immune modulators (Enbrel, Humira) (Meds that are often prescribed for patients with Eczema and Psoriasis)
- Antidepressants (Prozac, Zoloft, etc.)
- Antihistamines (allegra, Zyrtec, Benadryl)
- Histamine blockers (Pepcid, Zantac)
