About the Author

Genny Masterman is the founder of the Histamine Intolerance Awareness Campaign. She is an Associate Producer, Researcher and Journalist in the UK with a strong connection to the German language area. She has worked on over a hundred television documentaries for clients such as the BBC, CBS, ITV, Channel 5, the Travel Channel, the Austrian media and many independent production companies in the UK, US, and Canada. These include work as a Fixer on programs such as Top Gear, Who Do You Think You Are? with Marianne Faithful, Extreme Railway Journeys with Chris Tarrant, Richard Ayoade’s Travel Man – 48 hours in Vienna with Chris O’Dowd, George Clarke’s Amazing Spaces, Paul Merton in Europe, Al Murray’s Why Does Everyone Hate The English? with Henning Wehn and many more.

In 2007, after suffering for several years, she was diagnosed with histamine intolerance (HIT) and fructose malabsorption while in Austria during the production of a BBC documentary. Soon after her return to the UK she became aware that HIT is very low on the public radar in the UK in comparison to some countries in mainland Europe. She decided to change this. She gathered information, including the food lists, cooperated with experts and medical specialists in HIT from the German language area, and wrote a book documenting her story. Genny’s book “What HIT me? Living with Histamine Intolerance” was first published in January 2011. It has been regularly updated and is now in its 3rd edition. It is available on Amazon in English, German and Spanish. Up to now it has sold over 11.000 copies world-wide. It was the first comprehensive guide on the subject in the English language area. She continues to work in her spare time on raising awareness. She has made a full recovery from HIT.

About the Book

HIT – Histamine Intolerance – is a condition that affects many people but remains largely undiagnosed.  The symptoms can appear very like an allergy and can cause stomach and intestinal complaints, migraine, tiredness and skin problems, to name but a few. This is in most cases because of the reduced activity or low presence of an enzyme called diamine oxidase (DAO), which is mainly responsible for breaking down histamine and other biogenic amines ingested through food. Foods that are known culprits include: red wine, ready meals, cured meats, mature cheeses, tomatoes and aubergines. It can make people’s lives very difficult. But it CAN be brought under control with the RIGHT DIAGNOSIS and the RIGHT DIET. This book is a guide to how to achieve both. It helps both health professionals and patients gain insight.

After the great success of the first edition, this second edition contains a new section on the different points of view about diagnosis as well as a second food list – a tolerance index which resulted from a survey of 800 participants who judged 109 foods according to their individual threshold – side by side with the scientifically based food list.

From the Back Cover
Histamine is an important mediator of allergic diseases such as hay fever and bronchial asthma, food allergies, urticaria, and drug hypersensitivity. Knowledge of histamine as a cause of numerous non-allergic symptoms and signs is, however, limited. In fact, histamine intolerance can be responsible for conditions as diverse as seasickness, headaches and migraine, tachycardia, gastric disorders, diarrhea, intolerance to contrast media, parodontosis, period pains, nausea and vomiting in pregnancy, atopic dermatitis, and osteoporosis.

This book offers wide-ranging coverage of histamine intolerance. There is extensive background discussion of the origin of histamine, its content in food and alcoholic beverages, and intolerance to red wine. Diagnosis of histamine intolerance is explained, and the various symptoms of histamine intolerance are clearly described. Subsequent chapters cover the conditions mentioned above and also consider the relation of histamine to vitamin B6 and the specific immunotherapy of allergies.

This book will prove of value in clinical practice by facilitating differential diagnosis, which is by no means straightforward given the multiplicity of symptoms of histamine intolerance, and by assisting in the selection of therapeutic measures.
