Human nutrition

A.Y. 2020/2021
Overall hours
BIO/09 MED/49
Learning objectives
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.
Course syllabus and organization

Single session

Lesson period
Second semester
The lessons will be held on the Microsoft Teams platform and can be followed both in synchrony and asynchronous modes, as they are recorded and made available to students on the same platform.
If possible, some lessons will be in presence. The methods and criteria for participating to lessons in presence, as well as notices relating to any update related to the evolution of the legislation imposed by Covid-19, will be published in time on the Ariel pages.
The program and reference material will not change.
The exam will be written and by using the Microsoft Teams platform or, where the regulations allow, in person.
Course syllabus
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) and their nutritional roles
Impact of food processing on the nutritional characteristics of foods
Prerequisites for admission
Students need to have adequate knowledge of food components (general and organic chemistry), biological transformations that take place at cellular and human organism level (general biology and applied biochemistry).
Teaching methods
The professor will use lectures as the main teaching method, accompanied by classroom exercises for the calculation of body composition and energy expenditure. 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.
Teaching Resources
Slides provided by the teacher, available on the ARIEL platform

Assessment methods and Criteria
The exam will be written.
The verification takes place to evaluate 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.
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.
