Intolerances
- TyramineHigh
Fermented soy and fish products are among the highest-tyramine foods there are: they are protein fermented deliberately, for months, which is exactly the condition that builds tyramine. Soy sauce and fish sauce are used in small volumes but are very concentrated. Sources: EFSA Journal 2011 (tyramine and histamine in fermented foods); McCabe-Sellers et al., J Food Compos Anal 2006.
- GlutenContains
standard soy sauce is brewed with wheat and contains gluten. Choose tamari labelled gluten-free as a safe alternative.
- Histamine (+liberators / DAO inhibitors)Moderate
fermentation produces large amounts of histamine, so fermented foods are high in histamine no matter how fresh they look. There is no low-histamine version of a fermented product.
