How to distinguish the real green food from the fake one?

Green food is getting more and more popular among consumers and varieties of green food are increasing on market. But we have found that fake green food has come into the market. Then, how to distinguish the real green food from the fake one? Actually, it is not a complicated matter.

When every kind of green food comes to the world, Green Food Development Center of China, the administrative department of green food, has issued it an "ID" card, which is composed of two parts????one is the green label for green food which can only be used for the food authorized as green food, and the other is a serial number beginning with LB for green food, and we can take it as the serial number of 'ID' card of the food; each green food has a different serial number.

Currently, fake green food at the market has only the characters of "Green Food" on its package, but without any green label, or has just a fake green label but without any serial number for green food. So, all consumers, please attention, only the food with both a green label and a serial number for green food can be the real green food, or it is a fake one.
