This paper reviews the currently research on competency of practitioners in the field of nutrition and food hygiene at home and abroad. Through literature review

it's found that the there are few researches on competency in China at present. Furthermore

compared with foreign countries

there are several issues in China

such as the methods and index system setting. However

due to different national conditions

there are significant differences in the demand for nutrition and food hygiene practitioners

related disciplines and characteristics between China and abroad. Therefore

when drawing lessons from foreign models

we should appropriately make adjustments according to China's national conditions. This review will provide references for further research on establishing a set of scientific and standardized competency evaluation indexes for practitioners in the field of nutrition and food hygiene with Chinese characteristics.
