Ground meat (vegan)

Vegan meat alternatives often rely on flavor boosters and fermented ingredients that are known to be higher in histamine.

• Fermented ingredients are common — yeast extract and similar additives used for flavor often undergo fermentation, which naturally increases histamine content; not all soy-based ingredients are fermented, so checking the specific form matters

• Additives vary by brand — some products use simpler ingredient lists than others, so the histamine load can differ quite a bit depending on what's inside

Checking the ingredient list for yeast extract, fermented flavorings, or vinegar can help you compare options before choosing.
