A new approach to establishing an upper or prescriptive level of recommended intakes of nutrients was devised for use in Britain. It was based on present food supplies in the UK, and the following measures were proposed to improve the national diet: moderate reductions in intakes of fat, sugar, meat, and alcohol; increased intakes of cereals, potatoes, and other vegetables and fruit; while intakes of milk and eggs and fish, pulses, and nuts were to remain unchanged. The proportions of food energy derived from protein would be increased, despite reduced meat consumption. Nutrient content of the diet may be expressed in terms of food groups or as nutrient concentrations per energy unit, which is particularly applicable to planning or prescribing diets for individuals or small groups. The suggested changes in the national diet are large enough to be meaningful, yet would not disrupt agricultural or trade policies if implemented over the next decade. Furthermore, the methods used to assess the recommended intakes of nutrients are flexible enough to be used both for planning and prescribing diets and for evaluating results of dietary surveys or histories.
英国设计出一种新方法来确定营养素推荐摄入量的上限或规定水平。该方法基于英国目前的食物供应情况，并提出了以下改善国民饮食的措施：适度减少脂肪、糖、肉类和酒精的摄入量；增加谷物、土豆以及其他蔬菜和水果的摄入量；而牛奶、鸡蛋、鱼类、豆类和坚果的摄入量保持不变。尽管肉类消费量减少，但来自蛋白质的食物能量比例将增加。饮食中的营养成分可以用食物类别来表示，也可以表示为每能量单位的营养浓度，这特别适用于为个人或小群体制定饮食计划或规定饮食。国民饮食建议的变化幅度足够大，具有实际意义，但如果在未来十年实施，不会扰乱农业或贸易政策。此外，用于评估营养素推荐摄入量的方法足够灵活，既可以用于制定饮食计划和规定饮食，也可以用于评估饮食调查或饮食史的结果。
