Food waste and obesity and overweight conditions are both linked to the unsustainability of current food systems. This article argues that overnutrition should be considered a form of food waste and it provides a first estimation of the quantity of food over-consumed in Italy. This is done by calculating the excess calories consumed by obese and overweight people and converting them into food quantities by comparison with a typical Italian diet. The total quantity of food consumed in excess by Italian citizens due to overnutrition is calculated as 1.553 million tonnes per year, which is comparable to the current national household food waste assessments. The environmental impact arising from production and consumption of this food accounts for 6.15 Mt of CO-eq per year, as estimated by a Life Cycle Analysis conducted on the 46 food categories which compose the typical Italian diet. Overnutrition in the South-Islands regions of Italy exerts the largest impact (31.6%), followed by the North-West (26.6%), the Centre (22.2%), and the North-East (19.1%).
食物浪费与肥胖和超重状况均与当前食品系统的不可持续性有关。本文认为，营养过剩也应被视为一种食物浪费形式，并首次估算了意大利国内食物过度消费的数量。具体做法是，通过计算肥胖和超重人群所摄入的多余卡路里，并与典型的意大利饮食进行比较，将其转换为食物的实际数量。意大利公民因营养过剩而过度消费的食物总量，每年约为 155.3 万吨，与当前国内家庭食物浪费评估量相当。通过对构成典型意大利饮食的 46 种食物类别进行生命周期分析，估算出生产和消费这些食物所产生的环境影响为每年 61.5 公吨二氧化碳当量。意大利南部岛屿地区的营养过剩问题影响最大（31.6%），其次是西北（26.6%）、中部（22.2%）和东北部（19.1%）。
