PLEASE READ THIS PARAGRAPH FIRST!
This blog covers my personal journey with mast cell disease and histamine intolerance. I’m not advocating that you should follow the diet I follow, or that my diet is perfectly low histamine. I tried a basic low histamine diet, based on information from the International Chronic Urticaria Society, because I was having anaphylactic reactions every time I ate. Only 4 months into the diet these reactions no longer happened. This particular version of a low histamine diet works for me – it may not be right for you. There is much confusion about which foods contain histamine, block DAO or are histamine liberators: please read my blog post on the Truth About Food Lists for my personal thoughts on the accuracy of low histamine food lists and keep reading below for a more thorough explanation. You might also like to read my post To Eat or Not to Eat for more detailed reasons on why I eat the foods that I do.
A large part of treating mast cell disease, especially if you have significant Gastro-intestinal issues or have reactions after eating, is to follow a low histamine diet. It’s an absolute mine-field. There appears to be very few research papers or clinical trials into the histamine content in food, although I did find a link to the histamine levels in a small sample of foods on the Food Intolerance Network website. Added to that, the diets purported online can’t agree on even the most basic of food groups: some say wheat is fine so long as it’s unbleached flour and yeast free, some say no wheat. Some say bananas are fine, others say no bananas. You get the drift.
The Food Intolerance Network did a study on the reactions of over 800 histamine intolerant patients to various foods, and their results can be found here. As it states quite clearly, each individual will be able to tolerate different foods depending on where they are in the treatment of their histamine intolerance. Non-tolerated, and tolerated foods, will vary enormously from person to person depending on their individual reactions and from food to food, depending on how it’s been picked, stored and transported. It really is a game of trial and error, and there are only a very small list of foods that everyone with histamine issues reacts badly to (red wine, beer, tinned tuna, tomatoes, strawberries, oranges).
Of course, it’s more complicated than just the histamine content of food. There are also foods which are purported to block the DAO enzyme needed to ‘mop up’ histamine (eg. tea), and foods which don’t contain histamine per se but are purported to liberate histamine already in the body (eg. cocoa, nuts and some fruits). I use the word “purported” deliberately, as I’m unclear how these conclusions have been reached.
There is also the fact that you’re cutting out large groups of foods but not replacing them with much of anything. If you’ve had mast cell issues for some years your body is probably going to be in a state of utter disarray. It needs to be slowly built back up, and good nutrition is the key. I personally don’t have the time or energy to become obsessed with my diet, but I do try to buy organically wherever possible and include fresh fruit and vegetable juices. Juicing from scratch is a total faff if I’m honest, is expensive (you need a lot of produce for a small amount of juice), it assumes you already have a good juicer, and many juices are a bit like drinking medicine (!), but it’s a great way to feed your body easy to digest nutrients without having to think about complicated recipes. There are some juicing recipes on my Recipe page, or if you’d like to look into this further I highly recommend The Raw Energy Bible by Leslie Kenton. Not only are the juicing recipes in this book adaptable for a low histamine diet, but so are many of her raw food recipes.
I started off following a quite strict low-histamine diet and found I was both miserable and starving half to death. So I relaxed, and just cut out the worst offenders, however I’m aware this won’t be feasible for some people who will have to stick to a very rigid diet in order to control their symptoms.
Below is the diet I’m (loosely) following (taken from the International Chronic Urticaria Society website): This diet excludes all:
- foods with naturally high levels of histamine
- fermented food
- artificial food colouring, especially tartrazine
- benzoates including food sources of benzoates, benzoic acid and sodium benzoate
- butylated hydroxyanisole (BHA) and butylated hydoxytoluene (BHT)
Items marked with an * are considered controversial and excluded, or included, by other versions of a low histamine diet.
Most of all, remember the List below is just a guide. No definitive list of low histamine foods exists anywhere in the world!

If you want a stricter low histamine diet, try the Mastocytosis Society of Canada’s list of allowed & restricted foods, although you’ll soon notice that they allow foods my diet does not and visca versa!
Acetic Acid: I’m really conflicted about this ingredient. On the one hand it is, I think (!), made from a process of fermentation and is the main component in vinegar. However it is NOT vinegar, which is made by a further fermentation process. Acetic acid is naturally occurring in body fluids and plant extracts and plays a role in body metabolism. Although an E number (E260) it is not artificial and has no known contraindications to human health. It’s present in lots of commercial products, including some bread, as it inhibits mould growth and has antibacterial properties. Unless someone with much more knowledge than me can tell me I shouldn’t be eating it, it’s on my ‘allowed’ list occasionally and in small quantities.
