PRINCIPLES OF DIETETICS
Learning outcomes of the course unit
The course provides: The basic elements for the definition of the nutritionally adequate diet for
the different population subgroups;
The description of major methods designed to measure food and/or
nutrient intakes in population groups.
Moreover, a special attention will be paid on the description of nutrient
and non-nutrient composition of the main foods usually consumed in the
Basic knowledge of biochemistry provided with the core course of Biochemistry

body multicompartments and of the main techniques for measuring the
body multicompartments. 2) Anthropometric techniques for the
measurements of fat-free mass and fat mass.
PART II: ENERGY REQUIREMENTS: 3) Energy requirement and energy balance between daily intake and energy expenditure; 4) Total daily
energy expenditure and its components (resting metabolic rate, thermic
effect of foods and cost of physical activity); 5) Methods to evaluate
food energy (i.e., calorimetric bomb) and to measure energy expenditure
(i.e., direct and indirect calorimetry); 6) Energy needs of the adult
population, including different physiological conditions (i.e., pregnancy,
lactation) and in the elderly; 7) Basics on metabolic regulation.
PART III: FOOD GROUPS AND DIETARY GUIDELINES: 8) general concepts

recommended dietary allowances for Italian population (LARN: Livelli di
assunzione di riferimento di energia e nutrienti); 10) Dietary Guidelines
for the Italian population: general concepts and their scientific bases; 11)
Description of criteria to formulate a nutritionally adequate diet; 12) Food
guide pyramids and their description.

Frontal classes with the use of slides, web sites etc. During classes, problems dealing with the course content will be discussed and solved together.
Assessment methods and criteria
At the end of the course, a written test will be submitted to assess the level of competence acquired. Final exams (Oral) will be preceded by a problem-solving test.
