Overview
About fish sauce
Fish sauce is one of the highest-histamine ingredients in the kitchen.
It is made by fermenting salted anchovies for months, and that slow breakdown of fish protein loads it with histamine and tyramine. On top of that it acts as a histamine liberator, nudging your body to release its own histamine, so even a splash in a stir-fry or dressing can trigger flushing, headache or a racing heart if you have histamine intolerance. It also carries moderate free glutamate, the umami compound behind its savory depth.

How fish sauce scores
Watch for
What trips people up
- Very high in histamine because it is aged fermented anchovy, a classic trigger for flushing, hives, headache or a stuffy nose
- Doubles as a histamine liberator, so it can set off symptoms beyond its own histamine load
- High in tyramine, which matters if you are on an MAOI or get tyramine-linked migraines
- Moderate free glutamate gives the umami kick but can bother people sensitive to MSG-like additives

FAQ
Common questions about fish sauce
Is fish sauce high in histamine?
Yes. Fish sauce is made by fermenting salted anchovies for many months, and that aging produces large amounts of histamine along with tyramine. It is one of the highest-histamine condiments you can buy, which is why even a small amount can trigger flushing, headaches or hives if you have histamine intolerance.
What can I use instead of fish sauce if I react to it?
Reach for savory seasonings that are not fermented: a little salt for saltiness, fresh lemongrass for aroma, or nutritional yeast for a mild umami note. All three are far lower in histamine and tyramine than fermented fish sauce.
Does fish sauce contain MSG or glutamate?
Fish sauce is not made with added MSG, but fermentation naturally produces free glutamate, which is what gives it that deep umami taste. The level is moderate, so people who are very sensitive to glutamate may still notice it.
