Learning objectives

At the end of the training activity, the student will acqure knowledge and skills related to the effect of nutrients/food/diets on human metabolism in the various physiological states. In particular, about knowledge and understanding skills, the student will be able to: 1) Understanding the processes of digestion and absorption of nutrients and other food components ; 2) Understanding how the human organism regulates the utilization of nutrients and energy substrates in the metabolic phases and how foods and nutrients affect the human organism; 3) understanding the metabolic bases of diet-related diseases; 4) being able to predict how changes in food composition, formulation or processing may affect the nutrition quality of human diets. About communication skills, the student will be able to present scientific issues in support or against a nutritional case study.

Course unit content

ALIGNMENT: the course will be introduced by some basic concepts of human nutrition in order to align students with different study backgrounds. In particular, it will include a brief description of human physiology of the gastro-intestinal tract and accessory glands; digestion and absorption of macro- and micro-nutrients; concepts of bioavailability and essentiality of nutrients; nutritional quality of carbohydrate, protein and fat. The core course will then continue on the following tipics: METABOLIC REGULATION: 1) metabolism during the postabsorptive and fasting phases; 2) metabolism during the postprandial phase; 3) integration of carbohydrate, protein and lipid metabolism among tissues and organs. ENERGY BALANCE: 1) measure and estimation of energy intake and expenditure; 2) energy balance and body composition. DIET-RELATED DISEASES: 1) chronic diseases linked to over-nutrition; 2 ) nutrient deficiencies and diseases linked to under-nutrition. 3) dietary fibre and intestinal function

2) David A. Bender Introduction to Nutrition and Metabolism. 5th Ed. CRC Press, 2014, Boca Raton, FL (USA)
3) Selected scientific papers. 4) Notes and slides presented by the teacher

Teaching methods

Teaching will be carried out through classroom lectures and seminars, with the possibility of partly using the lessons also remotely in asynchronous mode (uploaded on the Elly page of the course), with the aid of slides that will represent educational material available online on the Elly platform in pdf format for students. During classrooms examples of numeric and problem-solving exercises will be proposed

Assessment methods and criteria

Final examination will be carried out trough a written test that will include different types of open, numeric and closed questions. In case of mark >18/30, the student will be offered the choice of accepting the mark or undergo a further oral exam, focussed on the errors done during the written test. If it will be impossible to take the exam face-to-face due to rules imposed by the University, both written and oral exams will be carried out remotely through an interview through the Teams portal, including quizzes and/or problems offered trough the ELLY portal.
The final evaluation, in 30/30 score points, will depend on the assessment of the level of knowledge of the contents discussed during the course, of the ability to use sources of scientific information and on the following aspects:- Knowledge application; - Ability to analyze complex dataset and cases and draw conclusions; - Communication skills; Ability to gain knowledge. The praise is assigned in the case of reaching the maximum score on each item to which is added the mastery of the disciplinary lexicon.
