The Beginner's Guide to Histamine Intolerance – Dr Janice Joneja

A brief introduction to the Beginner's Guide with editor Michelle Berriedale-Johnson and Dr Janice Joneja


If you’re struggling with your health, but the doctor can’t find anything actually wrong with you, then perhaps you have Histamine Intolerance. It’s a condition with a range of unpleasant symptoms, which can include headaches, flushing, itching, hives, swollen facial tissues, racing heart, digestive problems, irritability and more. 

Many doctors don’t know much about Histamine Intolerance, although it’s estimated that 1% of the world’s population suffers from it. If you’re one of them, you’ll know first-hand how distressing and frustrating the disorder can be.

Dr Janice Joneja saw the misery that this condition caused sufferers, and made it the focus of her research work; she’s been studying the condition and helping patients since the 1990s. Many visitors to this site will already have read some of her articles.

And she has now created this easy-to-read guide—which will help you understand if you have Histamine Intolerance, and, if so, what you can do about it—with clear advice and explanations, lots of interesting real-life cases, plus diet and treatment recommendations. 

If you wonder if your symptoms could be caused by Histamine Intolerance—or if you believe they are and want to know what to do about it—this book is for you.

You can buy the e-book on Amazon here in the US ($7.72) –
and here in the UK (£5.99)

A printed book will be available in September 2017

Jessica St Clair:

The Beginner's Guide to Histamine Intolerance has offered an eye-opening glimpse into the possible source of baffling allergic-type reactions I've been bombarded with for years (severe headaches, racing heart, chest pain, hives, itchy face followed by acne flare-ups, indigestion, etc.). An array of symptoms that left multiple doctors perplexed and unable to make a diagnosis, mostly negative allergy tests, the lack of knowledgeable guidance, and exasperation with constant symptoms motivated me to become my own health advocate and delve into researching what could possibly be going awry inside my body.

I'm so thankful I came across Dr. Janice Joneja's articles online and now this book, as her expertise offers valuable insight into the source of the symptoms that plague me, and offers hope that there is something I can do to help manage them. This book also inspired me to visit my doctor and request blood tests to check for underlying causes of excess histamine, so they can be treated appropriately if needed.

For the first time in this long, exhausting, lonely journey, I finally feel like I've been pointed in the right direction to find answers and wellness! Thank you Dr. Joneja!!

Micki Rose – naturopath and nutritionist:

This is great! Most people will buy it for the extensive, clear histamine diet section, but the case studies and Q&A are invaluable and no doubt people will recognise their own situations in them and feel relieved they know what it is! 

Useful to be reminded that that histamine ‘intolerance’ is in fact no such thing; it is neither allergy, nor intolerance, but more a condition of histamine excess from inside and outside the body and an inability to break it down sufficiently. I liked the analogy of the bucket overflowing and Janice recommends you use the diet to keep the bucket level controlled. 

Importantly, this book shows you whether it is likely to be histamine intolerance as opposed to allergy or MCAS, although I would have liked a little more on distinguishing it from food intolerance rather than allergy. It shows you, if it is HIT, what to do about it – mostly the diet but using DAO supplements (links given) and antihistamines etc can help. Janice does say DAO tests are not worth it, but mentions lots of times how boosting DAO helps so I personally think testing might help at least try and establish if low DAO is the issue behind it. 

Now we know why headaches and reactions get worse with hormone change and also why reducing stress can make such a difference. 

Excellent. Clear, concise and trustworthy advice from an experienced practitioner. I shall be recommending this to my patients when I’m asked: ‘Is it histamine intolerance?’ I shall say: read this; it’ll save me tons of time!

Allergy Insight – Alex Gazzola -

The release of The Beginner’s Guide to Histamine Intolerance by one of the world’s leading experts in the subject, Dr Janice Joneja, is good news. It may be aimed at those who have or believe they have histamine intolerance, but it’s extremely useful to those who merely want a readable and well-written primer on the subject too.

The first surprise is that diagnosis, if it can be called that, is one of exclusion, in part. If certain conditions – allergy, autoimmune, mast cell disorders – have been ruled out by doctors, and a histamine-restricted diet resolves symptoms, sensitivity to histamine can be assumed.....
