Every week, on average, every Italian throws away almost 7 ounces of food. To be precise, according to the estimates of the International Waste Watcher Observatory, this is 667.4 grams of food per head, a quantity unfortunately growing by almost 18% in the last year. Frozen food, however, does not seem to follow this trend: according to the same Observatory, which carried out an analysis for the Istituto Italiano Alimenti Surgelati (Iias), this is only 14.9 grams, just 2.2%.
Not only that: in the last five years, the consumption of 'frozen food' has increased, but this growth has not been matched by a similar increase in its wastage, which from 2021 to 2025, has remained stable (just over 2%), "confirming the valuable waste-saving virtues of these foods," emphasise Iias.
Frozen foods are in the top 10 of the least wasted foods: their wastage is 37.6% less than that of fresh vegetables and 17.4% less than that of non-fresh vegetables and fruit (in jars or pots).
According to the research, moreover 34% of Italians say they never waste frozen products. Among those who do, the most common causes are poor household organisation or interruption of the cold chain.
"Frozen foods are anti-waste champions not only in terms of food, but also in terms of time and cost: unequivocal," emphasise Iaas, "is their convenience, given the sum of time and food saved, as well as the costs of purchasing and preparing the products.
