The problem of collecting detailed dietary information on a large population scattered throughout England, Wales and Scotland was resolved by use of a 7 day dietary diary, introduced at home interviews. Information on food types and quantities was coded to provide data on a wide range of nutrients. Reported levels of iron and fibre intake were found to be particularly low in relation to current recommended daily intakes, which were more often achieved by men than by women. Best dietary habits were associated with good educational attainment, whatever the social class of origin, but in women this was in some circumstances associated also with relatively high intakes of alcohol, protein and fats. Worst dietary habits were associated with low social class of family of origin and low educational attainment. Mean intakes of some nutrients varied significantly by region, in most cases independently of class and education. The implications of these findings are discussed.
通过在入户访谈中采用7天饮食日记，解决了收集散布在英格兰、威尔士和苏格兰各地大量人群详细饮食信息的问题。食物种类和数量信息被编码，以提供关于多种营养素的数据。与当前推荐的每日摄入量相比，铁和纤维的摄入量水平尤其低，而且男性比女性更常达到推荐摄入量。无论出身社会阶层如何，最佳饮食习惯都与良好的教育程度相关，但在女性中，在某些情况下这也与相对较高的酒精、蛋白质和脂肪摄入量有关。最差的饮食习惯与出身家庭的低社会阶层和低教育程度相关。某些营养素的平均摄入量在不同地区有显著差异，在大多数情况下与阶层和教育无关。讨论了这些发现的意义。
