1, bookkeeping method is a dietary survey method, which is mainly used in collective units, such as schools, factories, military, etc. This method mainly records the types and quantities of food consumed by each person in a certain period of time, and then makes a summary analysis to understand the dietary status of the unit.
2. The advantage of bookkeeping method is that it can obtain a large amount of data and comprehensively reflect the dietary status of collective units. At the same time, because it is carried out regularly, it can track and compare the dietary changes in different time periods, which is very helpful to evaluate the effect of nutrition improvement measures. In addition, bookkeeping can also be used to study food consumption patterns and eating habits, providing a basis for formulating nutrition policies.
However, the bookkeeping method also has its limitations. First of all, it mainly depends on the respondents' consciousness and accuracy. If the respondents don't carefully record or remember clearly, it may lead to data deviation.
4. Secondly, the bookkeeping method can't get the individual's dietary intake, but only the collective average intake, which may not be accurate enough for evaluating the individual's nutritional status and health status. In addition, the bookkeeping method can't obtain information such as cooking methods and food quality, which are important factors affecting the nutritional value of food.
