Since the start of reform and opening-up, the diets of Chinese people have undergone significant changes. In the past, due to a less developed economy, limited food varieties, and widespread shortages, people were merely content with having enough to eat. Today, alongside China's rapid economic development, not only has the variety of food expanded greatly, but its quality has also improved considerably. As living standards continue to rise, people have higher expectations for their food, paying increasing attention to nutrition and health. Consequently, low-fat, low-sugar, and organic foods have become widely popular on the market. There is no doubt that improvements in food quality and dietary structure have provided a strong guarantee for enhancing public health.
