Histamine sensitivity, or histamine intolerance, can cause a range of symptoms that often feel like allergic reactions. These symptoms happen because of too much histamine building up in the body, affecting various systems. Common symptoms include headaches or migraines, hives and itching, nasal congestion and runny nose, flushing, and digestive issues like bloating and diarrhea. For those dealing with histamine intolerance, changing their diet is key to feeling better. A low-histamine diet can help reduce symptoms by cutting down on foods and drinks that are high in histamine or trigger its release. Knowing which foods to avoid and which ones are safe can make a big difference in managing histamine intolerance and keeping a balanced diet.

Low Histamine Diet | Basic Rules

  1. Fresh Foods: Opt for fresh foods rather than processed ones. Fresh fruits and vegetables, fresh meat, poultry, and fish are generally lower in histamine compared to their processed counterparts.

  5. Fresh Fish: Freshly caught or freshly frozen fish is preferable. Avoid aged or smoked fish.
  6. Grains: Most grains are considered low in histamine, so include rice, quinoa, oats, and gluten-free options if needed. For bread – Sourdough and gluten free options tend to be lowest in histamines.
  7. Dairy Alternatives: Opt for dairy alternatives like coconut milk, or rice milk instead of dairy products, which can be high in histamine.
  8. Herbs and Spices: Use fresh herbs and spices in cooking instead of pre-packaged ones. Fresh herbs like parsley, basil, and cilantro are good choices.

  11. Limit Alcohol and Vinegar: Alcoholic beverages, especially wine and beer, as well as vinegar-containing foods like pickles and mustard, can be high in histamine.

Supplements to Help with Histamine Sensitivity

  1. Quercetin: Quercetin is a natural antihistamine that stabilizes mast cells, reducing histamine release and alleviating allergy symptoms.
  2. Vitamin C: Vitamin C helps degrade histamine in the body, reducing symptoms like nasal congestion and skin issues.
  1. DAO Enzyme (Diamine Oxidase): DAO enzyme supplements support the breakdown of histamine in the digestive tract, reducing digestive symptoms related to histamine intolerance.
  2. Vitamin B6 (Pyridoxine): Vitamin B6 acts as a co-factor for the DAO enzyme, enhancing the body’s ability to process histamine and alleviate related symptoms.
  3. Probiotics: Certain probiotic strains, such as Lactobacillus rhamnosus and Bifidobacterium longum, help balance gut flora and reduce histamine production, improving overall gut health.
