For decades, the dietary structure, health and disease mortality rates for Shanghai residents have changed dramatically. In 1992, animal food intake increased five-fold from 1959, and the heat gain from fat rose from 9.0% in 1959 to 27.9% in 1992. As a result of dietary changes, the state of health and disease mortality have also changed. For example, the average height of a 17-year-old male in 1955 was 167.19 cm.
