10 strategies to improve food tolerance

• Consciously reduce intake of histamine‑rich foods

These include, for example, aged cheeses, smoked meats, canned fish, sauerkraut, soy products or vinegar. Certain fruits and vegetables such as eggplant, oranges or kiwis are also on the list.

• Choose low‑histamine foods deliberately

Opt for fresh, well‑tolerated foods like fresh cheese, fresh meat, just‑caught fish, many vegetables and selected fruits such as apples or berries. Keep in mind that tolerance to low‑histamine foods can vary between individuals.

• Prefer fresh ingredients

Where possible, choose unprocessed, fresh ingredients over highly processed or aged products. When shopping, look for short ingredient lists and high quality, since industrially processed foods often have higher histamine levels.

• Store food properly and use it quickly

Cool freshly prepared meals as quickly as possible and store them in the fridge instead of leaving them at room temperature for a long time. Avoid reheating dishes multiple times or keeping them warm for long periods, as histamine can accumulate further in protein‑rich foods.

• Avoid products that can interfere with processing

Certain drinks and additives – for example black or green tea, energy drinks, alcohol and ingredients such as glutamate, sulphites or nitrites – can influence how the body processes histamine.

• Observe your individual tolerance

Personal tolerance to histamine can vary widely. Keep a food diary for several weeks, noting exactly what you eat and drink and how you feel afterwards.

• Check ingredient lists carefully

Take a close look at processed products. Additives such as yeast extract, flavourings or preservatives can be relevant for sensitive people. Prefer products with short, natural ingredient lists.

• Plan regular breaks between meals

Give your body time between meals, as it processes absorbed histamine gradually. Constant snacking can increase the overall burden.

• Plan a time‑limited elimination phase

A temporary reduction of histamine‑rich foods for about three weeks can be useful to relieve the body. Afterwards you can reintroduce individual foods gradually and observe over two days how well you tolerate them.

• Consider histamine releasers

Some foods such as citrus fruits, strawberries, chocolate, bananas or legumes contain little histamine but can promote its release in the body. Test such items carefully and watch your individual reaction.
