The aim of all dietary surveys is to discover what the persons under investigations are in habit of eating. They could be used to collect data on a single individual and on several hundred of individuals. There are two types of methods used: --evaluation of global consumption, --precise dietary studies. Additional studies research conscious and unconscious factors of dietary consumption. Whatever the aim, dietary patterns are used to trace trends both retrospectively and prospectively. But the nutritionist must be aware of limitations of the methods and be constantly improving them. It is imperative, therefore, that critical evolution be made at every stage of the procedure. The interest of those studies is to identify the current nutrient intake of a group or an individual likewise during a longer period, so that we can define the evoluation and perhaps the reason behind them. In epidemiological work, they are a part of the whole given data. They could permit the evaluation of correlation with clinical or biological parameters or with a particular disease.
所有饮食调查的目的都是为了发现被调查者的饮食习惯。这些调查可用于收集关于单个个体或数百个个体的数据。使用的方法有两种：——总体摄入量评估，——精确饮食研究。另外还有研究饮食消费的有意识和无意识因素的研究。无论目的是什么，饮食模式都可用于追溯和预测趋势。但营养学家必须意识到这些方法的局限性，并不断改进它们。因此，在该过程的每个阶段都必须进行批判性评估。这些研究的意义在于确定一个群体或个体在较长时期内当前的营养摄入量，以便我们能够定义其演变情况以及背后可能的原因。在流行病学工作中，它们是整个给定数据的一部分。它们可以用于评估与临床或生物学参数或特定疾病的相关性。
