BEIJING - Regulations on food packaging will take effect from January 1, 2013, in a bid to guide the public and reduce risks of chronic non-communicable diseases, a senior supervision official with China's Ministry of Health said Monday.

The regulations will provide standard nutritional information on food packaging labels, through which consumers can directly identify a product's nutritional structure and ingredients, said Su Zhi, the official, at a press conference.

The content of four kinds of nutritional elements, including protein, fat, carbohydrate and sodium, as well as the calorie count should be labeled on the packages, Su said.

Moreover, the regulations stipulate specific rules on labeling other nutritional content, names and functions, Su added.

Su said the regulations were first devised in 2007, based on experiences provided by international food societies as well as the country's own situation.

"China faces a severe situation of chronic non-communicable diseases, and information on the packages will help consumers avoid the intake of unhealthy elements, such as saturated fat and cholesterol, and increase the ingestion of dietary fibers," Su said.

According to the World Health Organization, 74.3 percent of countries in the world have made regulations on food packaging, Su said.
