Sintesi	The HDDS is a simple, 12-item food group checklist that captures the diversity of the household diet in the preceding 24 hours. Developed by the FAO in 2011 as a proxy indicator of dietary quality and nutrient adequacy, the HDDS enables rapid assessment of the nutritional vulnerability of households in resource-limited settings. A household with access to foods from many groups is more likely to consume adequate calories, protein, and micronutrients.	The HFIAS is a 9-item survey designed to measure the frequency and severity of food insecurity at the household level in resource-limited settings. Developed by the FANTA Project in 2007, it assesses four domains of food access: anxiety, dietary diversity, food consumption frequency, and household member deprivation. It is widely used in low- and middle-income countries for program evaluation and surveillance.
