The main aim of the UC is the study of the different food groups, the changes that occur in these foods during manufacture and storage and how they can be related to nutritional modifications and/or formation of toxic compounds to the consumers.
It is also intended that the students have ability to understand which foods intake is directly related to the early development of chronic diseases as well as foods that may decrease the likelihood of developing risk factors that are responsible for these diseases.
It is intended that the students will have the ability to understand the interactions that may exist between food and medicine.
Students must be capable of determining nutrients in foods and their caloric value and critically discuss the results. Students should also be able to perform techniques related to food spoilage.
