Abstract: Based on the food self-sufficiency rate (FSR), the mean value of FSR (M), and the coefficient of variation of FSR (CV), this research analyzed the security trends of the nine main food categories in China from 1991 to 2012, including grain, pork, beef and lamb, poultry meat, eggs, milk, aquatic products, fruits, and vegetables. The results showed that: 1) in general the grain production of China could not meet its own grain demand in the period of 1991-2012, meaning that grain was in an insecurity status. The main reason is that the portion of feed grain and the industry used grain increased too fast with growth rates of 3.34 times and 6.54 times of the food grain production growth respectively. 2) In the studying period, the supply of pork, beef and lamb, poultry meat, eggs, milk, aquatic products in China were far over their actual demands, meaning that meats and aquatic products were in a very safe status in that they not only meet the demand of domestic market, but also supply for international markets or for reserve. And 3) from 1991 to 2012, the security of fruits and vegetables demonstrated a linear increasing trend, and these two categories were also in a very safe status.
