Food waste is a very important factor in the Food and Nutrition Unit, and it is essential to carry out a study of this indicator through leftovers and food scraps in order to verify the performance of the unit, the diner's view in relation to the menu offered in addition to the costs generated. The objective of the present study is to evaluate the size of the rest-intake produced in the institutional cafeteria. This cross-sectional research was carried out in a UAN of the Federal Institute of Piauí, Campus Piripiri at the beginning of the second semester of 2018, in the months of August, September and October. Food waste was monitored by diners for a period of 30 days, from Monday to Friday (except holidays). To obtain the residues, the remains of food thrown in the trash by diners during a period of thirty days were weighed. A waste index was found far above that acceptable in the literature, reaching a total of 297.80 kg, with an average of almost 10 kg per day and in relation to per capita data, approximately 56 grams of food were discarded. It is concluded that it is necessary to carry out constant educational actions to raise awareness of the target audience.
