Low Histamine Diet – The Latest Research on Diet and Tests

In this video I interview Liane Reeves who is a specialist gastroenterology & allergy dietitian and one of the UK’s top experts in the Low Histamine Diet.

💡 What you'll learn:

• What histamine is, its normal roles in the body, and the enzyme (DAO) that breaks down the histamine we eat

• Factors that can affect DAO function, including certain medications, alcohol, genetics, gut damage, and competition from other amines

• The wide range of possible symptoms, and why these can overlap with allergy, stress responses, and histamine food poisoning (scombroid poisoning) from poorly stored oily fish

• Why there is currently no reliable blood test for histamine intolerance, and why a 2 to 4 week diet trial is the only practical way to assess it

• Why most fruit and vegetables are low in histamine and generally don't need excluding, and which foods most sources agree are genuinely high in histamine

• How to reintroduce foods safely and personalise the diet, and why nutrient replacement (iodine, calcium, vitamin D, omega-3) matters if avoiding dairy, oily fish, or other food groups

🎯 Who this video is for: Anyone with symptoms that may be linked to histamine intolerance, or already following a low histamine diet, wanting an evidence-based, less restrictive approach.

🩺 Disclaimer: This video features a discussion between two specialist dietitians and provides general educational information only. Histamine intolerance has no validated diagnostic test, and its symptoms can overlap with allergy and other conditions that need medical assessment. This diet is restrictive and is not suitable for anyone underweight or with food-related anxiety. Always seek advice from your GP or a registered dietitian before making significant dietary changes.
