Learning objectives
The teaching module aims to provide the fundamental knowledge and understanding in relation to the biochemical processes that characterize the nourishment and nutrition in the human body, as well as to deepen the complex issue of food and nutritional safety, in relation to the official control activities in food hygiene. In this context, the chemical-physical and qualitative characteristics of the nutritive principles and of the main classes of foods, the nutritional characteristics of foods, the functional and protective properties, the fundamental aspects of preventive dietetics are set out. The study of food safety issues contributes to the reinforcement of the regulatory contents dealt with in the field of integrated training activity and aims to develop, in particular, the methodology and the specific tools of inspection control in food hygiene.
Prerequisites
The prerequisites are represented by the knowledge of biology, chemistry and biochemistry.
Course unit content
The initial part of the teaching module deals with general topics of social medicine such as nutrition in today's society, the interaction of man with food, the general principles of food science and human nutrition; an in-depth study of nutrients, their biochemical and nutritional properties, their specific functions on human nutrition. The second part of the teaching module deals with the complex issue of food toxicology through an in-depth study of the characteristics of food contaminants and toxicological evaluation; the third part of the teaching module deals with food safety combined with nutritional safety, included in the reference national and EU Community regulatory framework, updated to the most recent sector laws and procedures.

Teaching methods
In relation to the educational objectives outlined above, the teaching of the course takes place through the implementation of lectures conducted with the help of slides and texts; similarly, during the teaching module, students are invited to participate in in-depth seminars related to the techniques of official food hygiene control. During the lessons, moreover, debate and discussions are held regarding the thematic areas covered by the didactic module. The student at the end of the course, also using the knowledge of biology, general chemistry and biochemistry already acquired previously, will have to highlight knowledge and understanding skills in relation to the biochemistry of nutrition and food, the nutritional principles and their use at internal processes of intermediate metabolism. Furthermore, through the knowledge and understanding also exercised in group activities, the student will have to identify the critical elements related to the analysis and assessment of food hygiene risk, elaborate the basic criteria for carrying out the official control activity, including the use of appropriate documentation. The course will be held through lectures to Students either in the classroom (“in presenza”) or in synchronous-streaming (“in telepresenza”) on the Teams platform. Therefore, the opportunity of Student/Teacher interaction will be preserved both face to face and remotely, by the simultaneous use of the Teams platform.
Lectures will be supported by slide presentations, which will be available to students on the Elly platform (https://elly.medicina.unipr.it).
Assessment methods and criteria
The learning outcomes are assessed through an oral exam which aims to ascertain the achievement of knowledge and understanding of all the contents of the training module. In case of the persistence of the health emergency, the exams will be conducted remotely, as follows:
remote oral questions, through the Teams platform (guide http://selma.unipr.it/).
Students with SLD / BSE must first contact Le Eli-che: support for students with disabilities, D.S.A., B.E.S. (https://sea.unipr.it/it/servizi/le-eli-che-supporto-studenti-con-disabilita-dsa-bes.
