Knowing the principles of physiology that underlie the processes of digestion and absorption of nutrients. Knowing the functions of macro-and micronutrients and the role of non-nutrients in the human body. Knowing the nutritional characteristics of foods in relation to the needs of the individual.
Expected learning outcomes
Students will acquire: expertise on the role of body composition, energy expenditure and functionality of the digestive system on the health status, compentence on the function of nutrients (proteins, lipids, carbohydrates, fiber, minerals and vitamins) have in the body and ability in evaluating the use foods as sources of nutrients.
Lesson period: Second semester
(In case of multiple editions, please check the period, as it may vary)
Human body and digestive system Anatomy and physiology of the digestive system (mouth, stomach, small and large intestine) and accessory organs as liver and pancreas Mechanisms of food digestion (proteins, lipids a carbohydrates) and nutrient absorption Body composition (BMI:Body Mass Index, FFm: Free Fat Mass, FM: Fat Mass) and energy metabolism (REE:Resting Energy Expenditure, DIT:diet-induced thermogenesis, exercise-induced thermogenesis) Water (water balance, thirst, osmosis, electrolytes) and related functions (chemical processes, temperature regulation, etc.) Metabolism and nutritional role of proteins (food proteins, non-protein nitrogen utilization), lipids (food lipids, cholesterol, alcohol, fat catabolism and synthesis, lipoproteins, omega3 and omega6) and carbohydrates (sugars, glycogen, starch, glycemic index, fructose, fiber) Interrelatins within sugars, proteins and lipids Food and nutrient needs Physical and chemical characteristics of dietary fiber and its nutritional role Mineral (macro and micro) and vitamins (hydro and liposoluble) nutritional roles Nutritional information on ¿ready to eat¿ foods: glycemic index, lipid oxidation, protein changes, vitamin and mineral lost, etc.
Prerequisites for admission
Possess adequate knowledge food components (general and organic chemistry), biological transformations that take place at cellular and human organism level (general biology and applied biochemistry).
The professor will use lectures as the main teaching method, accompanied by classroom exercises for the calculation. The course uses e-learning teaching material present on the Ariel platform consisting of the slides discussed during the lectures. Attendance to lessons is strongly recommended.

Assessment methods and Criteria
The exam will be written. The verification of the acquired knowledge of the human body, the physiology of the digestive system, the nutrients and their role in the body, and the food sources of nutrients takes place by written test. The test includes 60 multiple choice questions on food, digestive system, nutrient metabolism. The test has a total duration of 60 minutes. To take the exam it is necessary to register within the deadline set on the SIFA. Each student will receive the mark by automated e-mail from the university software.
