as is shown in the graph, china's food distribution has taken great changes from 1960's to 1990's according to this statistics of cereals, vegetable, meat, and fruits, the number of those who eat rice, flour or vegetable has greatly decreased in the past four decades. in contrast of this the number of those who eat oil or meat has sharply increased. from such dietary changes, we can perceive the rapid improvement of our people' s living standard.

　　why does this improvement occur? the direct reason is the fact that the chinese people have attached much importance to their health care. nationally, china's economic growth is booming, and more people are getting richer. inpidually, everyone's consumption of food is increasingly varied. in particular, most of people are reluctant to eat much vegetable, but much meat and oil in their diets.in my view, the changes of china's dietary distribution seem to be both positive and negative. the positive aspect is that china' s economical growth has given rise to the higher level of dietary standard, with most of people living rich and happy. but the negative aspect is that, i'm afraid, less eating vegetable will lead to poorer health, such as lacking vitamin nutrients in one's body. therefore, we think it necessary for the chinese to be aware of the balanced diets: lots of vegetable and meat, which may gain us healthier bodies in the new century.
