Feta: FODMAP, histamine, lactose and gluten

Here is what the scientific sources say about Feta for people managing sensitivities to FODMAP, histamine, gluten and lactose.

Histamine

The histamine/biogenic amine content of Feta is considered medium (0-3 intensity scale).

Foods. 2025;14(3):369. doi:10.3390/foods14030369 — su campioni commerciali di feta, istamina rilevata in un solo campione su tre a 26,76 ± 2,11 mg/kg, gli altri due sotto il limite di rilevabilità (ND). Dato integrato con Natrella G, Vacca M, Minervini F, Faccia M, De Angelis M. 'A Comprehensive Review on the Biogenic Amines in Cheeses.' Foods. 2024;13(16):2583. doi:10.3390/foods13162583 (Tabella 2, dato aggregato da uno studio precedente in letteratura) — istamina 49 mg/kg in feta da latte vaccino, con tiramina 77, putrescina 60, cadaverina 70 mg/kg.

LTP (lipid transfer protein)

The LTP risk associated with Feta is classified as low.

Sources: Egger M, Hauser M, Mari A, Ferreira F, Gadermaier G. 2010. The role of lipid transfer proteins in allergic diseases. Clinical and Experimental Allergy 40(11):1571-1580. — Le LTP sono proteine di difesa esclusive del regno vegetale, assenti nel latte e nei suoi derivati: la feta non contiene LTP, quindi il rischio di reazione LTP-mediata è nullo per questo alimento.

Lactose and gluten

Lactose is naturally present in Feta. Gluten is not naturally present in Feta.

It is not designed to handle anaphylactic reactions: in an emergency, contact emergency services immediately. You can declare, in free text, the substances you're allergic or intolerant to: an AI interprets them and the app tries to exclude them from scanner results, recipes, and products. This is a best-effort aid to reduce risk, not a safety guarantee: the underlying ingredient and product data isn't clinically validated allergen by allergen, and your declaration may be interpreted inaccurately. Always check the label yourself before consuming a product, especially for severe allergies.
