Starting a low histamine diet can definitely feel a little (or really!) daunting. It's frustrating to restrict foods you love, and unlike many other diets such as gluten-free and keto, a low histamine diet isn't widely known. I didn't know where to begin when I was starting a low histamine diet. Food shopping was a frustrating experience, and to begin with I ended up eating the same bland meals over and over as I couldn't find many suitable recipes.
But there is hope! Over the years I have learnt how to make a low histamine diet work for me. I really enjoy cooking the low histamine recipes I share here on the blog and I hope you find something you find tasty! All my recipes follow the SIGHI food list for histamine, and are for people advised to follow this guide by their medical team.

1. Consult a doctor
Starting a low histamine diet, and restricting yourself to low histamine foods, should always be undertaken on the advice of a trained medical professional. A change to your diet should always be undertaken after receiving expert medical advice. Please see my disclaimer on this issue in relation to the content of the blog.
2. Choose a low histamine diet
Once you have been diagnosed, seen a medical professional, and been advised to follow a low histamine diet, the next step is to choose which version of the diet you want to follow (best done with the guidance of a doctor or dietician). This may sound a little strange. After all, shouldn’t all low histamine diets be the same? Well, unfortunately histamine issues and food are fairly under-researched. There are a lot of different versions of the low histamine diet available online or through medical practice. I have been given lists that contradict each other by different doctors! Plus there are many lists online that contradict those as well.
It is too confusing to try and follow all of them so, as a dietitian suggested I do, it is probably best to choose a list and stick with it. The Swiss Interest Group Histamine Intolerance (SIGHI) one seems to be the most-often cited, and the one that I have been recommended by a few different doctors, which is why I use it for my recipes here. They have their own cookbook in case it is helpful. However, you should follow the advice of your own doctor or dietician. Also, be sure to speak with a dietitian or doctor if you feel that you are having issues with particular ‘allowed’ foods on it.
3. Focus on what you CAN eat not what you can't
Low histamine diets basically divide up foods into those ‘allowed’ and those ‘restricted’. The number of restricted foods is high, and includes very commonly used foods such as tomatoes, spinach and hard cheeses. It is very frustrating to feel restricted, so switch up how you approach it and focus on what you CAN eat. This might seem obvious, but switching up your mind-set can really help. If necessary draw up a list of foods that are allowed, and pin them to the fridge, put in a diary, or have on your phone so that you can check when you are making a meal or eating out. Also, see step 4 below for a little help with this!

4. Take a shopping list to the supermarket
Shopping when you eat a low histamine diet can be really frustrating. You can end up walking up and down the aisles of the supermarket feeling overwhelmed by all the food on offer that you cannot eat. To combat that, make a shopping list of all the foods that you can eat, and that you enjoy. I find that starting with fruit and vegetables helps as there are lots of items that can be enjoyed on a low histamine diet. Then work from there to 'packet' food such as rice, quinoa or pasta, and then allowed cheeses etc. If you would like some ideas for foods that you should be able to eat, then have a look at my low histamine shopping list for snacks, drinks and breakfast foods.
5. Focus on the macros
It might sound obvious, but make sure you are getting adequate amounts of the three primary macro-nutrients – protein, carbohydrate and healthy fats. I find that getting enough protein is more challenging than carbohydrates, so I make sure every meal has a protein source in it – allowed cheese, occasionally eggs, seeds etc (whether these are ‘allowed’ depends on the version of the diet you follow).
6. Focus on taste
Strong tastes, if that is what you enjoy, are a little absent from a low histamine diet. Lots of stronger tasting foods such as olives, feta cheese, balsamic vinegar are restricted. I found it really hard to not eat tasty, flavourful foods to begin with. Everything felt a little bland, and that is never appetising! Now I try and make sure that I use ‘allowed’ herbs, salt and spices such as turmeric and sweet paprika (not smoked). It makes meals tasty and keeps you from thinking about the foods that you cannot eat.
7. Make substitutions or omit ingredients
When planning meals be open to making substitutions, or just omitting a particular ingredient, when you are looking at recipes. Instead of thinking that you cannot eat a particular meal anymore, try and work out if a simple substitution will work. For example, a tomato sauce could be changed up for a roasted pepper one. Restricted herbs can be swapped for those that are fine to eat. Get creative!
My post on easy low histamine food swaps should be helpful!
It's also the case that we are all individuals and so can tolerate different foods. There may be foods that are rated as low histamine that you just can't tolerate, or foods that are higher histamine that you are fine with. So some recipes may need some swaps and substitutions for you personally.
8. Make sure you get enough calories
When I was first starting a low histamine diet I wasn’t eating enough calories and ended up losing weight. This was not a good thing for me personally. I was eating a lot of fruit and vegetables, but not enough calorific foods. Now I make sure that I eat higher calorie foods such as mozzarella, rice, pasta, porridge, seeds etc.
Using a calorie tracking app may help you to start with so that you can get an idea of how much, and which types of foods, are good for you. I used the Lifesum app when I first became aware that I wasn't getting enough calories. Today I now use it occasionally to track my macros (P.S. I have no affiliation with Lifesum - just the app that I used). It may also be a good idea if you wish to track your macros for a short period of time to ensure that you aren't lacking. Beware though - some apps put you on crazy low calorie diets - so check with a doctor or dietitian the right levels for you.
9. Check menus at a restaurant
Eating out on a low histamine diet can be a minefield. To be honest, it is not something I do that frequently. As well the question of whether the range of dishes on the menu are suitable, there is also the issue of food storage. Eating foods that have been prepared a long time in advance and are sitting out is not ideal. So options such as salad bars or carveries are likely to be problematic. If you decide to eat out, then check online and see if the restaurant or café has a menu. That way you can see what the options are before you dine. If there isn’t anything suitable then it may help to call ahead and ask if substitutions can be made or certain ingredients omitted from a dish.
10. Consult a dietitian
If you are starting a low histamine diet on the advice of your doctor then it may be worth having an appointment or two with a dietitian that specialises in low histamine diets. I did this on a private basis for a single appointment, and it was well worth the cost. The dietitian gave me a clear list of foods that were allowed (see the Low histamine diet page), and those restricted, and she also gave me a list of recipes and meal ideas that I could begin with. I felt much more confident after seeing her, and more sure of my choices. Super helpful!
You can also ask your primary doctor for a referral, if this is possible under your healthcare system. In the UK, you can ask for an NHS referral to see a dietitian, which would usually be in a hospital setting.
