Changes on the dinner table

Changes on the dinner table
Great changes have taken place on people's dinner table in the past thirty years.
Thirty years ago, people were so poor that they didn't have enough food to eat. They had to fill their stomachs with something unhealthy. Twenty years ago, people's life was better than before. They could make more money and had more food to eat.
In recent years, most people have led a better life. On the one hand, they can buy anything that they want to eat, such as seafood and all kinds of meat and fruits. On the other hand, people pay more attention to their balanced diets. They want to be healthier.
I believe people will lead a better life in the future.
