Take this book everywhere! It'll help you at home, in a restaurant, out with friends, at the bar, in the supermarket and in any situation when you are not sure about histamine levels in food or drink.

Up to 20% suffer from histamine intolerance and don't even know it. It's time to heal.

Congratulations on choosing this book. We wrote it because we suffer from histamine intolerance ourselves, and we were frustrated at how so much information out there seems to confuse us and conflict with other sources.

This book works like a dictionary. Look for a food, drink or ingredient alphabetically or on search.

Every ingredient gets a score between 1 and 5 for histamine levels and detailed comments where appropriate. It's so easy!

5 indicates the least amount of histamine (or histamine-releasing or DAO blocking)

1 indicates the most amount of histamine (or histamine-releasing or DAO blocking)

It's simple - the higher the score the better.

We decided to take the world's best and most trusted histamine intolerance lists and guides and compile the information into one easy-to-consult guide.

We know that this list is not perfect, because that's the nature of histamine intolerance. But we believe it is the most comprehensive food and drink list out there.

The Histamine Heroes are a group of authors and experts in health and wellness, and we would like to see more information out there about histamine intolerance. We find it frustrating that there is so little good knowledge out there, particularly in the area of supplements. That's why we've compiled this book.

Remember: Take this book everywhere and start to truly understand your histamine intolerance.
