Unsaturated fat
Unsaturated fat is fat whose molecules carry one or more double bonds, liquid at room temperature, found mostly in vegetable oils, nuts, seeds, avocado and oily fish. IZeat counts unsaturated fat inside an item's total fat, at the same energy per gram as any fat, and does not store the split; a label that gives it can be read by the assistant.
Monounsaturated and polyunsaturated fats, olive oil and fish oil among them, share the energy factor of all fat, about 9 kcal per gram, so for a record they count the same as butter. Where they differ is in the health conversation, which is not IZeat's. The one place unsaturated fat matters to the record is the cooking question: a dressing or a frying oil is often the largest unmentioned item on a plate.
People underestimate oils because they are poured, not weighed, and a generous tablespoon is close to 120 kcal. IZeat's assistant asks how much oil when the words leave it open and records it as its own item, so the day shows it rather than hiding it inside a dish. A customer who measures their oil once learns more from one record than from any list of good and bad fats.
