In judging from what is detailedly demonstrated in the above table,we can observe distinctly that significant changes have taken place in people's diet since 1986,which clearly indicates the improvement of citizens'liveing standard.One of the major changes is the decrease of grain consumption with 49 percent in 1986 and 45 percent in 1990.At the dinner tables of inhabitants the traditional dominant food-grain has given some way to milk and meat,which were seldom seen on dinner tables before.Since the economic reform in 1978,various kinds of food have become popular in Chinese families. Nevertheless,there is a steady reduction of fruit and vegetables with 24 percent in 1986 and a three-point drop by 1990.However,this is not the main trend.As the living standard of the Chinese people is rising,we look forward to further changes in civilians'diet.The proportion of fruit and vegetables as well as milk and meat will definitely increase in the coming years.
