You make low-histamine soups without tomatoes, spinach, aged cheese, pulses or shop-bought stock – instead, use fresh veg like potatoes, squash, parsnips, carrots or fennel. Water with salt and herbs is often enough; if you want stock, make your own from veg. How much histamine you tolerate is individual. If you have a medical condition, talk to your GP or a dietitian.
Soups made from fresh veg without tomatoes, spinach, pulses, aged cheese or shop-bought stock – for example potato, squash, parsnip or fennel soup. Every recipe here is checked with fixed rules: none of its ingredients is on our list of known histamine sources and histamine releasers, which is based on the SIGHI list.
Shop-bought stock, stock cubes and stock powder often contain yeast extract or glutamate, so our rule leaves them out. Homemade vegetable stock from fresh veg is fine; bone broth and meat stock are not. Many soups here don’t need stock at all.
It’s best eaten fresh. Histamine can build up in cooked leftovers while they’re stored, especially with meat or fish. Cool anything left over quickly and freeze it in portions.
