1.在联合王国，可供人类消费的食物和饮料总量将提供约13 MJ（3100千卡）/人/天，而推荐的人群能量摄入量约为9.6 MJ（2300千卡）/人/天。这一巨大差异的一部分必然是由于家庭以及餐饮机构和食品储存、分配和加工过程中的浪费。2.作为这个问题的一般调查的一部分，1000个英国家庭的代表性样本被要求收集所有潜在的可食用的食物浪费在他们的家中在1周内，并保持食物的记录，而不是商业宠物食品，他们给宠物和野生鸟类。共有672户人家充分合作，夏季338户，冬季334户。每一个收到的食物样品都被称重，并通过热量测定其能量含量。3.夏季收集的废弃食物明显多于冬季，分别相当于每周9.3 MJ（2220千卡）/户和每周7.1 MJ（1700千卡）/户。在能量方面，谷物、脂肪和肉类的消耗占主导地位，而在体重方面，牛奶更重要，脂肪则较少。4.此外，亦有相当数量的其他可食用食物给予宠物及雀鸟，平均每户在夏季及冬季每周分别额外消耗2.4兆焦耳（570千卡）及3.0兆焦耳（710千卡）。因此，在家中浪费的所有食物的能量含量在夏季平均为11.7兆焦耳（2790千卡）/家庭每周，在冬季平均为10.1兆焦耳（2410千卡）/家庭每周，分别相当于0.6兆焦耳（150千卡）和0.5兆焦耳（130千卡）/人每天。这还不到英国食品供应与人们认为的食物摄入量之间的差距的四分之一。5.食物浪费受家庭组成的影响很大，成年人浪费的绝对值比儿童多，大家庭人均浪费比小家庭少。然而，除了少数例外，收入和地理区域都没有显著影响家中浪费的食物总量。6.当与家庭中食物的预期使用量进行评估时，浪费平均占夏季能量摄入量的6.5%和冬季的5.4%。
1. The total food and drink available for human consumption in the United Kingdom would provide approximately 13 MJ (3100 kcal)/person per d, while the energy intake recommended for the population is approximately 9.6 MJ (2300 kcal)/person per d. A proportion of this substantial difference must be due to wastage in the home as well as in catering establishments and during the storage, distribution and processing of food. 2. As part of a general investigation of this problem, a representative sample of 1000 British households was asked to collect all the potentially-edible food wasted in their homes during 1 week, and to keep a record of the food, other than commercial pet food, which they gave to pets and wild birds. A total of 672 households co-operated fully, 338 in summer and 334 in winter. Each food sample received was weighed, and its energy content was determined calorimetrically. 3. Significantly more waste food was collected in summer than in winter, equivalent to 9.3 MJ (2220 kcal)/household per week and 7.1 MJ (1700 kcal)/household per week respectively. In terms of energy, cereals, fat and meat wastage predominated, while in terms of weight, milk was more important and fat less so. 4. Considerable quantities of otherwise edible food were also given to pets and birds, accounting on average for a further 2.4 MJ (570 kcal) and 3.0 MJ (710 kcal)/household per week in summer and winter respectively. The energy content of all food wasted in the home therefore averaged 11.7 MJ (2790 kcal)/household per week in summer and 10.1 MJ (2410 kcal)/household per week in winter, equivalent to 0.6 MJ (150 kcal) and 0.5 MJ (130 kcal)/person per d respectively. This is less than one-quarter of the gap between food supplies and the amount of food thought to be eaten in the UK. 5. Food wastage was significantly influenced by the composition of the family, with adults wasting more in absolute terms than children, and larger households wasting less per person than smaller households. However, with few exceptions, neither income nor geographical region significantly affected the total amount of food wasted in the home. 6. When assessed against the expected usage of food in the home, wastage accounted on average for 6.5% of the energy intake in summer and 5.4% in winter.
