Anti-histamine diet Expert Views

Dr. Corinna Geiger, a gastroenterologist specializing in Mast Cell Activation Syndrome (MCAS), discusses the potential benefits of a low histamine diet for Long Covid patients. She explains that symptoms from high histamine levels can be managed by reducing histamine overload, which can be achieved through dietary changes. Dr. Geiger also highlights the importance of addressing environmental factors, such as dust allergies, which can contribute to histamine burden. She emphasizes the interconnectedness of gut health, sleep, and hormone regulation in managing Long Covid symptoms.

Moira Newiss, a nutritional therapist, explains that a low histamine diet can be beneficial for individuals with mast cell activation syndrome, a condition linked to immune system hypersensitivity. This syndrome can worsen after COVID-19, leading to symptoms like fatigue, muscle pain, and headaches. The diet involves avoiding high-histamine foods such as fermented items, aged cheeses, and certain vegetables like tomatoes and avocados. However, she emphasizes that responses to histamine vary among individuals, and experimenting with the diet is essential. She also notes that gut-related issues are often where the diet shows the most success, and medical advice is recommended to confirm the condition.

Lily Spechler, a registered dietitian, explains that mast cells, which are immune cells, are highly active in areas like the gut, lungs, and skin. COVID-19 interacts with these cells through ACE2 receptors, leading to overstimulation and the release of chemicals like histamine. While a low-histamine diet can help reduce symptoms, it often doesn't lead to complete healing. Spechler emphasizes the importance of addressing malnutrition and gut health, particularly by increasing short-chain fatty acids through fiber consumption. She warns against low-fiber diets, like carnivore diets, as they can harm beneficial gut bacteria and worsen gut permeability.

Joachim Gerlach, chairman of Vedicinals, discusses the use of anti-histamine therapy for Long Covid, emphasizing the importance of understanding the root causes of histamine issues. He explains that histamine problems can stem from mast cell activation, which is often triggered by IgE from B cells. Addressing these triggers may involve calming mast cells, improving B cell differentiation, and tackling underlying issues like leaky gut or dysbiosis. Gerlach also highlights the role of probiotics in managing histamine levels, recommending probiotics that degrade histamine rather than promote its production. He stresses the need for integrative approaches and communication between doctors specializing in pharmaceuticals and nutraceuticals.

Professor Mary Hickson discusses the potential use of a low histamine diet for Long Covid patients, particularly those experiencing symptoms like fatigue and brain fog. She notes that while some individuals try this diet to manage symptoms potentially linked to Mast Cell Activation Syndrome (MCAS), there is no scientific evidence supporting its effectiveness. Hickson emphasizes the risks of restrictive diets, such as malnutrition, and advises that anyone considering this approach should seek professional guidance and monitor their nutritional status carefully. She also highlights the importance of setting a time limit for trying such diets and stopping if symptoms do not improve.

Dr. Tina Peers, a specialist in Mast Cell Activation Syndrome (MCAS), discusses the benefits of a low histamine diet for managing Long Covid symptoms. She notes that some patients report feeling better within three days of starting the diet, which can lead to dramatic improvements. Dr. Peers recommends following the Swiss histamine interest group (SIGHI) list of histamine foods, as it is medically sanctioned and avoids contradictory information found online. She also advises using apps to help with shopping and dining choices. Additionally, Dr. Peers suggests introducing antihistamines gradually, starting with over-the-counter options like loratadine, cetirizine, or fexofenadine, and adjusting based on individual response.

Carrie Bailey, a functional nutritionist, discusses the anti-histamine diet as part of a broader elimination diet for managing Long Covid. She emphasizes removing foods that drive histamine production, such as vinegars, citric acid, and processed foods. Citric acid, often found in condiments and canned goods, is highlighted as problematic due to its production from genetically modified corn and mold. Bailey also warns against natural flavors containing MSG, which can harm the brain. She advises reading food labels carefully and reducing fat intake to improve nutrient absorption and toxin elimination.

Rachel Whitfield, speaking on the Long Covid Podcast, shared her experience with the anti-histamine diet while recovering from Long Covid. She initially tried the diet but found it confusing and challenging, especially as a vegetarian. Rachel emphasized that elimination diets should be short-term to identify problematic foods, but she observed that some people end up cutting out too many food groups, which can lead to nutritional issues and difficulty reintroducing foods later. She personally opted for a balanced 'rainbow diet' and highlighted the importance of hydration and addressing stress responses for recovery. Rachel also mentioned that while some people find the low histamine diet helpful, it’s crucial to consult a professional before making drastic dietary changes.
