Low Histamine Diet

Low Histamine Diet for Long COVID, Vaccine Injury, and Mast Cell Activation Syndrome (MCAS)

​

A low histamine diet can be beneficial for individuals experiencing Long COVID, vaccine injury, and Mast Cell Activation Syndrome (MCAS). These conditions often involve heightened immune responses and inflammatory processes in the body. Histamine, a mediator released during these immune responses, can significantly contribute to symptoms. By managing histamine intake through diet, individuals can alleviate some of these symptoms and improve their overall quality of life.

Why a Low Histamine Diet Can Be Helpful

Histamine is a biogenic amine involved in local immune responses, regulating physiological functions in the gut, and acting as a neurotransmitter. It plays a crucial role in allergic reactions and inflammatory processes. In conditions like Long COVID, vaccine injury, and MCAS, the body's immune system may be overactive or dysregulated, leading to excessive histamine release. This can result in symptoms such as:

• Headaches

• Fatigue

• Gastrointestinal issues

• Skin rashes

• Respiratory problems

• Cardiovascular irregularities

Mediators and Histamine

In these conditions, various mediators, including cytokines, leukotrienes, and prostaglandins, are released by immune cells. Histamine is one of the most potent mediators. It can increase vascular permeability, leading to swelling and redness, stimulate gastric acid secretion, and cause smooth muscle contraction, affecting the respiratory and gastrointestinal tracts.

By adopting a low histamine diet, individuals can reduce the overall histamine burden on their bodies, helping to manage and mitigate symptoms associated with these conditions.

Low Histamine Foods

Choosing foods that are low in histamine can help manage symptoms. Here is a list of foods that are generally considered low in histamine:

Low Histamine Foods:

• Fresh meat and freshly caught fish

• Eggs

• Fresh fruits (excluding strawberries, tomatoes, avocados, and bananas)

• Fresh vegetables (excluding tomatoes, spinach, eggplant, and avocados)

• Gluten-free grains (such as rice and quinoa)

• Dairy alternatives (such as coconut milk and almond milk)

• Olive oil

• Herbal teas

High Histamine Foods to Avoid

Certain foods are high in histamine or can trigger the release of histamine in the body. Avoiding these foods is crucial for those on a low histamine diet:

High Histamine Foods:

• Aged cheeses

• Processed meats (such as salami and sausages)

• Fermented foods (such as sauerkraut, kimchi, and yoghurt)

• Alcohol (especially wine and beer)

• Vinegar and foods containing vinegar (such as pickles and mayonnaise)

• Dried fruits

• Certain vegetables (such as tomatoes, eggplants, spinach, and avocados)

• Certain fish (such as mackerel, sardines, and tuna)

Supplements to Help Control Histamine Release

In addition to dietary changes, certain supplements can help control histamine release and breakdown in the body:

1. DAO Enzyme:

Diamine oxidase (DAO) is an enzyme responsible for breaking down histamine in the gut. DAO supplements can help individuals with histamine intolerance by reducing the histamine load in the digestive system.

2. Quercetin:

Quercetin is a flavonoid with natural antihistamine properties. It can inhibit the release of histamine from mast cells and has anti-inflammatory effects.

3. Vitamin C:

Vitamin C is known to help lower histamine levels in the blood. It can also support the immune system and improve overall health.

4. Bromelain:

Bromelain, an enzyme found in pineapples, has anti-inflammatory properties and can help reduce histamine levels.

5. Magnesium:

Magnesium plays a role in stabilizing mast cells, thereby reducing histamine release. It can also support overall cardiovascular health, which is beneficial for individuals with POTS.

6. Probiotics:

Certain probiotic strains, such as Lactobacillus rhamnosus and Bifidobacterium longum, can help maintain gut health and reduce histamine production.

Conclusion

A low histamine diet, combined with appropriate supplements, can be an effective strategy for managing symptoms associated with Long COVID, vaccine injury, and Mast Cell Activation Syndrome. By reducing histamine intake and supporting the body's ability to break down and manage histamine, individuals can experience significant relief from their symptoms. As always, it is essential to consult with a healthcare professional before making significant dietary or supplement changes, especially for those with underlying health conditions.
