Cheddar
Cheddar is high in Histamine and Tyramine. If you're sensitive to any of these, check it against your profile before eating.
Intolerances
- Histamine (+liberators / DAO inhibitors)High
The aging time is supposedly 14 months. If the product is aged for less time, it may contain lower levels of histamine.
- TyramineHigh
Aged cheese is the reference tyramine food — the 'cheese effect' is named after it. Bacteria break the milk protein down over months and decarboxylate its tyrosine, so tyramine tracks ageing almost linearly: a mature cheddar or a blue can exceed 100 mg/kg while a fresh cheese sits near zero. Cooking does not destroy it, and it keeps rising in the fridge after opening. If you take an MAOI antidepressant this is the single most important food to avoid — a large portion can trigger a hypertensive crisis.
