根据下表提供的数据，写一篇说明文，简述过去几年来某地区人们饮食结构的变化，以及这些变化带来的益处。Changes in

This table shows the changes in people’s diet in the past four years. We can see that the amount of grain and meat people eat fell slightly year by year. It means that people now eat less staple food than before. Instead, people spend more on milk, fruits and vegetables.
What causes the changes? The answer is that great changes have taken place in our country. For one thing, people earn more money and can afford more expensive food. Their request is not only to eat enough but also eat nutrient food. For another thing, people begin to pay more attention to the structure of their diet. They come to realize that reasonable structure of the diet does a lot of good to their health.
In short, our country is developing more and more rapidly. People’s life will become happier than ever before and people will become healthier than ever before.
