Since the beginning of reform and opening-up, the diets of Chinese people have undergone remarkable changes. In the past, due to economic underdevelopment, food varieties were limited and often insufficient, so people were merely concerned with having enough to eat. Today, with rapid economic growth, food has become not only more abundant and diverse but also significantly higher in quality. As living standards continue to rise, people are placing greater emphasis on their diets, paying more attention to nutrition and health. As a result, low-fat, low-sugar, and organic foods introduced to the market have gained widespread popularity.
