Food labeling is one of the essentials in informing the buyer at the time of purchase. People have different needs due to their different physical conditions, hense pay attention to the contents and labels of the food they consume. Due to the increasing use of packaged products, the public awareness and health of the community, Labeling is an important tool for informing consumers and measuring the health of products that should be used optimally and with high efficiency to play an important role in reducing noncommunicable diseases. The present study was conducted in the form of a library study using related articles in databases and search engines. Also, the laws and regulations for labeling of Canada, England, Japan, Australia and New Zealand, South Africa, UAE, Malaysia, Turkey, the European Union and the food codex have been reviewed and compared with the existing criteria in Iran. The results of this study showed that about 90% of the international laws related to labeling in different countries are the same as in Iran. According to previous studies, due to the excessive amount of information contained, the time limit while buying food products on the one hand and the illegibility of some information in the labels and their distortion, as well as their incomprehensibility on the other hand, The labeling policy has not been met. This study reveals the need for a coherent plan and the need to unify the labels of all food products to avoid consumer confusion and indecision in the field of food labels.
