I am vegetarian.
'Vegetariano' = veh-jeh-tar-YAH-no — five syllables. Stress on the fourth. Feminine: 'vegetariana.'
Mention when food is being discussed or when invited for a meal. In Italy, dietary restrictions are taken seriously by hosts and restaurants. Stating it upfront avoids awkward situations.
'Sono vegetariano/a' — no article after essere when describing a category or identity. The adjective agrees with gender. In Italy, vegetarian awareness has grown significantly, though traditional cuisine is very meat-centric.
Sono vegano/a.
I am vegan.
Stricter than vegetarian — increasingly understood and accommodated in Italian cities.
Non mangio carne.
I don't eat meat.
Practical statement — explains the restriction without labeling yourself.
Ho un'intolleranza al lattosio.
I am lactose intolerant.
Food intolerance — important to mention to Italian hosts who use cheese and cream liberally.
Traditional Italian cuisine is very meat and fish-heavy, but pasta, pizza, and many vegetable dishes are naturally vegetarian. Italian hosts are generally creative and accommodating once informed of dietary preferences.
