Since the launch of reform and opening up，Chinese people’s diet has undergone significant changes. In the past，due to economic backwardness，there was a limited variety and insufficient quantity of food，so people were satisfied with merely having enough to eat. Nowadays，as China’s economy has grown rapidly，not only has the variety of food available increased，but the quality has also greatly improved. As living standards continue to rise，people have higher demands for their diet and pay more attention to eating nutritiously and healthily. Therefore，the low-fat，low-sugar，and organic foods currently available in the market are widely welcomed.
