As is shown in the four pictures, there has been great change in Chinese diet since 1980s. Twenty years ago, people in the village always had corn, steam corn buns, sweet potatoes and vegetables as their main food. The urban people were comparatively rich, so they can afford the expensive dishes of rice, meat, eggs and fish daily. Nowadays it seems, to our surprise, the village people and city residents have exchanged their dinner tables.
The phenomenon reflects that people’s diet concept is changing while their living standard is progressing. On the one hand, with the improvement of the villagers’ living standard, the proportion of high-nutrition food, such as eggs and meat, has also increased in their diet. On the other hand, as many modern-day diseases, such as hypertension, high levels of blood lipids, and diabetes, are found to be diet-related disorders, the city dwellers have become more health-conscious, and they prefer the low-protein and high-fiber food to high-fat meals.
Of course, we can’t judge hastily which eating habit is better, because only a balanced diet can benefit people’s body. However, it is a pleasure to see more and more Chinese people are pursuing a better life by choosing a varied and balanced diet.
