Low-Histamine Diet

What Is the Low-Histamine Diet?

Histamine is a type of neurotransmitter known as an amine that is most well known for its role in itchiness, swelling and other allergic symptoms. It is not typically a natural component of food, although some foods naturally contain high amounts of it. Instead, it is usually created as a byproduct of some amino acids by certain kinds of bacteria, usually in the fermentation, curing or aging processes.

A low-histamine diet may not typically be the first diet that is used for reversing chronic health symptoms. Instead, an elimination diet or a gluten-free, dairy-free diet are usually the first diets tried, and we agree with this approach. The low-histamine diet is often a secondary, refining diet that is explored if symptoms continue to persist. Having your child follow it can help to reduce inflammation and lowering exaggerated immune-system responses.

Because of histamine’s ability to exacerbate allergic and immune responses, a low-histamine diet can be helpful in reducing symptoms of numerous autoimmune, gastrointestinal and neurological conditions such as:

What’s Excluded in a Low-Histamine Diet?

Foods that contain high levels of histamines are excluded in this diet. Foods that are fermented, cured or aged are almost always excluded. In addition, there are unprocessed, natural foods that are also high in histamine. High-histamine foods include, but are not limited to:

  • Avocado
  • Sauerkraut
  • Kim chee
  • Pickled vegetables
  • Other fermented foods
  • Aged cheeses
  • Most yogurt
  • Buttermilk
  • Chocolate
  • Citrus fruit
  • Eggplant
  • Tomatoes and tomato sauce
  • Yeast-containing foods
  • Pineapple
  • Pork
  • Processed, cured or smoked meats and fish
  • Soy sauce and tamari
  • Spinach
  • Tofu and other fermented soy
  • Vinegar
  • Beer
  • Wine
  • Chicken liver
  • Strawberries
  • Leftover foods
  • Slow-cooked foods

The inclusion of leftover foods may cause a double take, but it makes more sense when you know that certain bacteria produce histamine as a byproduct. The longer these bacteria remain through fermentation or the aging process – which includes leaving foods as leftovers, the more histamine there will be.

Does My Child Need to Follow the Low-Histamine Diet Forever?

While the elimination of high-histamine foods can control symptoms, it isn’t reasonable to think that a child should avoid these foods for the rest of their life. The good news: This is probably not a lifelong diet for your child IF you continue to work towards healing the gastrointestinal system, detoxing the liver and removing or remediating potential triggers.

Heal the Gut

Because histamine is by and large created by certain types of bacteria, it is important to correct gut dysbiosis so that there are less of these bacteria present. Removing histamine-containing foods and other inflammatory foods can be an important step, but bringing the gastrointestinal system back into balance is the ultimate goal. Gut-healing diets such as the following can help:

Detox the Liver

A properly functioning liver is necessary for the breakdown of histamine. Therefore, a poorly functioning liver may lead to histamine sensitivity. Naturopaths and homotoxicologists are well versed in detoxing the liver safely and gently for your child.

Remove or Remediate Potential Triggers

Chronic infections and exposures can continue to trigger histamine sensitivity. Be sure to look into:

If, after following these steps, histamine intolerance continues to be a problem, we recommend working with a practitioner that’s knowledgeable about Mast Cell Activation Syndrome. A naturopath or functional-medicine practitioner is a good starting point.
