Overview
About Gochujang
Gochujang is a Korean fermented paste built from chili powder, fermented soybean, glutinous rice and salt, sweetened with barley malt or added sugar and aged for months.
It stacks several triggers at once, which is why it can flatten someone who handles plain chili or plain soy sauce separately. Nightshade is its highest rating, because gochugaru is the backbone of the paste rather than a garnish. The long fermentation pushes both histamine and tyramine high and generates a lot of free glutamate. The barley malt and wheat mean it grades as a gluten-containing food rather than a gluten-free one, which surprises people who assume a chili paste is naturally safe. On top of that it rates poorly for low-fermentation and SIBO plans, with moderate FODMAP and fructan loads from the grain and sweeteners.

What trips people up
- Most gochujang is not gluten free. Traditional recipes use barley malt powder to drive the sweetening step and many commercial jars add wheat flour outright, so it grades as a gluten-containing food. Certified gluten-free versions do exist, but you have to look for the certification rather than assume it.
- Top of the scale on nightshade. Gochujang is largely gochugaru by volume, so a tablespoon in a marinade is a far bigger capsicum dose than a shake of chili flakes, and it is a common reason a nightshade elimination fails without anyone noticing why.
- High on both histamine and tyramine after months of fermentation. That combination is worth flagging if fermented foods give you flushing, hives or headaches, and the tyramine load is the one to raise with your prescriber if you take an MAOI.
- High in free glutamate from the fermented soybean, and plenty of brands add MSG as well. If umami-dense sauces reliably bring on head or facial symptoms, this is one of the strongest glutamate sources in a typical fridge.
- Rated poorly for low-fermentation and SIBO protocols, with moderate FODMAP and fructan content from the rice, malt and added sugars, so a generous spoonful is doing more to a sensitive gut than the heat alone would suggest.

FAQ
Common questions about Gochujang
Is gochujang gluten free?
Usually not. Barley malt powder is a traditional part of how gochujang is sweetened during fermentation, and many mass-market jars also list wheat flour, so it grades as a gluten-containing food. A handful of brands now make and certify a gluten-free version using rice alone. For coeliac disease, read the ingredients on the specific jar every time, because recipes differ between brands and between export and domestic versions.
Is gochujang high in histamine?
Yes. It is fermented for months, and long fermentation of a protein-rich soybean base is a classic route to high histamine. It rates high on tyramine for the same reason. If you have histamine intolerance, gochujang belongs in the same mental category as aged cheese, soy sauce and miso rather than in the fresh-chili category, and the amount used in a stew or marinade is not small.
Is gochujang a nightshade?
Yes, and heavily so. The paste is built on gochugaru, Korean chili powder, which comes from Capsicum annuum, the same nightshade family as peppers, tomatoes, potatoes and aubergine. It carries the highest nightshade rating on our scale. Anyone doing an AIP or nightshade elimination has to remove gochujang and anything built on it, including tteokbokki sauce, many bibimbap sauces and most Korean barbecue marinades.
Is gochujang low FODMAP?
It grades moderate rather than low. The glutinous rice, barley malt and added sugars contribute FODMAPs and fructans, and the paste also rates poorly for low-fermentation and SIBO plans. Small amounts may sit fine, but it is not a free food on a low FODMAP diet, and the quantity used in a sauce is usually well past a test serve.
