Understanding Histamine Intolerance
What if I told you that some of the healthiest foods on earth might be the reason you feel foggy, have skin rashes, itchiness, or bloating? Foods like avocados, spinach, and fermented items can trigger these uncomfortable symptoms. If your allergy tests come back negative, but you feel sensitive to almost everything you eat, you may simply have a condition known as histamine intolerance.
What is Histamine?
Most people associate histamine with antihistamines used for seasonal allergies. However, histamine is crucial for your immune system. It helps produce stomach acid and triggers brain signals. When you face an injury or infection, your immune cells, known as mast cells, release histamine, which dilates your blood vessels to increase blood flow for healing.
Sources of Histamine
Histamine comes from two sources: your body and your diet. Imagine your body has two interconnected buckets for histamine—one intestinal and one systemic. You start experiencing symptoms like itching, hives, flushing, brain fog, or migraines when the systemic bucket overflows.
The Role of Enzymes
At the bottom of each bucket is a filter, an enzyme known as HNMT (histamine N-methyltransferase) for the systemic bucket and DAO (diamine oxidase) for the intestinal bucket. If the HNMT enzyme removes histamine faster than the mast cells release it, you won’t feel any symptoms. However, if the bucket fills up faster than it empties, you experience histamine intolerance.
Foods High in Histamine
Many healthy foods are surprisingly high in histamine, including aged cheeses, processed meats, fermented foods like sauerkraut or kimchi, and alcoholic beverages, particularly wine and beer. Moreover, certain foods like avocados, tomatoes, and spinach also contribute to histamine levels.
How to Manage Histamine Intolerance
To alleviate histamine intolerance, consider these actionable steps:
1. Adopt a Low-Histamine Diet
Start by reducing your intake of high-histamine foods, including aged cheeses and fermented products. Alcohol is particularly detrimental; it’s high in histamine and also inhibits the DAO enzyme, worsening your symptoms.
2. Limit Alcohol Consumption
Alcohol not only adds histamine to your system but also impairs your body’s ability to break it down. If you suspect histamine intolerance, drastically reduce or eliminate alcohol from your diet to see if your symptoms improve.
3. Consider DAO Supplements
Another approach involves taking DAO enzyme supplements, like the ones from OmneDiem, which come from pig DAO. While plant-based supplements exist, they are often less effective. Their standard product, Histamine Digest, contains 30,000 HDU (histamine degrading units), with variations ranging from 15,000 to 40,000 HDU.
4. Monitor Your Overall Health
Remember, DAO supplements only help at the intestinal level. If you have chronic conditions like arthritis or Ehlers-Danlos syndrome, where you may have ongoing low-level inflammation, you might still need to modify your activities to alleviate the overall burden on your tolerance levels. This way, even if a small amount of dietary histamine leaks through, you can better manage it.
Next Steps
If you suspect you have histamine intolerance, start implementing these dietary changes and consult a healthcare professional for further guidance. Understanding how histamine works in your body can empower you to make informed choices about your diet and health.
