HIT: What can I eat?

The most important measure to take is to observe a low-histamine diet.

There are a couple of basic rules that you should keep in mind:

  • No preserves, canned or bottled food products
  • No over-ripe foods (matured cheeses, alcoholic beverages, products produced with yeast, less than fresh fish...) 
  • Histamine levels can vary! Depends on the maturation/ripening stage and hygienic condition of the product. 
  • No alcohol, especially not before, during or after meals. 
  • Always make sure to tell any physicians treating you that you have histamine intolerance. This applies especially when you undergo surgery under anaesthetic!
  • Always keep your emergency set with you (as prescribed by your doctor) 
  • Certain medication should be avoided. (Ask your doctor! )
  • Always eat food directly from the refrigerator; don’t take it out of the refrigerator to let it warm up before you eat it.

The following foods should be avoided in general:

  • Ahigh_histamine_levelslcoholic beverages
  • Hard (matured) cheese
  • Salami
  • Nuts
  • Tomatoes
  • Fish (except for very fresh fish)
  • Tuna (even when it’s fresh)
  • Shell fish
  • Sauerkraut    

You can find a more detailed list of tolerated and not tolerated foods here, and here in the histamine table.
