12 Signs You Have A Dangerous Histamine Intolerance (Doctors Always Assume It’s An Allergy)

Histamine intolerance, which look and feel like an allergy, are not well understood in the medical world. Consequently, they’re not often recognized and treated accordingly. Although only 1 % of the population experience unwanted effects to normal levels of histamine in food, the sensitivity to histamine has become very common these days.

Although histamine is naturally found in the body and many foods, problems occur when its levels fall out of balance.

Histamine intolerance as a result of decreased exercise of histamine-degrading enzymes may stimulate the release of histamines during the inflammatory response.

Many foods contain histamine or trigger their release in the body. The problem arises when there is an influx or overload of histamine and the body is unable to break it down. These intolerances are caused by impaired enzymes activity, classified into four issues:

-Enzyme inhibitors (certain medication or foods)

-Enzyme competitors (biogenic amines)

-Enzyme genetic defects

-Enzyme production issues (inflammatory bowel diseases or food deficiencies)


Histamine intolerance is usually manifested by rashes, trouble respiration and nasal congestion. However, the reactions could vary and flare up in issues like the ones below:

  • Low blood pressure
  • Irritability
  • Low sex drives
  • Nausea
  • Migraines
  • Racing hearts
  • Brain fog
  • Digestive problems
  • Anxiety
  • Fatigue
  • Eczema
  • Hormone imbalances


Even though foods vary in their histamine levels, their reaction is pretty much the identical. Whether meals are low or excessive in histamine they still stimulate the release in the body similarly.


  • Mushrooms
  • Nuts
  • Shellfish
  • Smoked meat products, like bacon
  • Spinach
  • Vinegar
  • Bread and gluten-rich meals
  • Canned meals
  • Bone broth
  • Alcohol
  • Cheese
  • Eggplants


  • Tomatoes
  • Avocados
  • Bananas
  • Citrus fruits
  • Strawberries


  • Get professionally tested for a histamine intolerance

To be able to determine if the body is unable to process the histamine-rich meals in your food plan or break down this compound, you need to have a doctor run labs, in search of high histamine ratio.

  • Find the root problem

Since histamine intolerance are sometimes secondary reaction to other inflammatory issues, you should also be tested for issues like gluten intolerance, nutrient deficiency, and leaky gut syndrome.

  • Follow an elimination food plan

Remove or reduce high-histamine foods and reintroduce them after a month or two to be able to discover which one of these foods caused the issue in the first place.

  • Focus on fresh meals

Try to eat as much fresh, low-histamine diet as possible, such as fresh veggies, gluten-free grains, rice milk, fresh wild-caught salmon, or herbal teas.

  • Heal the gut

Ingested foods are not the only cause for histamine overproduction in the body and most of these issues may be solved by gut micro organism imbalances. In order to fight off candida overgrowth or leaky gut syndrome, you should eat more probiotics.

  • Eat histamine-combating foods

Vitamin B6, copper, and vitamin C have the ability to help the body eliminate excess histamine, meaning that you should eat more foods packed with these nutrients in order to fight histamine intolerance.
