  8. Data collection • Nine days: • Firstday: general informationonthehouseholdandresidents • Forms to include informationonfoodacquisitionandconsumption • Fromthesecond to theeighthdays: • Interviewersvisitthehousehold to followthefillingoftheforms • Twononconsecutivefoodrecords • Ninethday: closing
