Learning outcomes

At the end of the course, students will know and understand the physiological determinants of energy and nutrient requirements, food composition, regulation of food intake, nutritional status assessment, and the main interactions between nutrients and drugs.
Students will be able to estimate energy and nutrient requirements under different physiological conditions, analyze dietary intake, use food composition tables, and apply the main methods for assessing nutritional status.
Students will be able to critically interpret dietary, anthropometric, and nutritional data, evaluating dietary adequacy in relation to individual requirements and nutritional recommendations.
Students will be able to use appropriate scientific terminology to communicate nutritional assessments and collaborate with other healthcare professionals.
Students will have developed the ability to independently update their knowledge through the critical consultation of scientific literature and relevant guidelines.

Prerequisites

To understand the course content, students should have basic knowledge of human anatomy and physiology, biochemistry, cell and molecular biology, food chemistry, and human nutrition, acquired through the first-year courses in the Degree Programme.

Lessons mode

Teaching activities are mainly carried out through lectures, structured progressively to ensure a comprehensive understanding of the physiological determinants of energy and nutrient requirements, the mechanisms regulating food intake, and the principles underlying the assessment of nutritional status. Lectures are complemented by interactive activities, such as guided questions, discussions, and case study analyses, which promote active participation and the development of a critical approach to evaluating dietary adequacy, estimating nutritional requirements, and interpreting nutritional status indicators.
Occasionally, elements of the flipped classroom approach are introduced through the provision of preliminary reading materials or additional resources, allowing part of the classroom time to be dedicated to discussion and problem-solving activities. Particular attention is also given to the use of technical and scientific language, encouraging students to re-elaborate and communicate concepts using appropriate terminology, in accordance with the expected learning outcomes.

Frequency

Attendance at teaching activities is compulsory, as established by the Degree Programme Regulations. Regular participation in lectures is strongly recommended, as it supports the acquisition of the knowledge and skills expected from the course, also through discussion activities and the analysis of case studies proposed during the course. To be admitted to the examination, students must attend at least 67% of the course's scheduled teaching activities.

Exam mode

A single written examination covering the three modules (Applied Dietetic Sciences for Energy Requirements, Applied Dietetic Sciences for Nutrient Requirements, and Applied Dietetic Sciences for the Assessment of Nutritional Status).
Objectives: Assessment of theoretical knowledge, analytical and synthesis skills, and the appropriate use of scientific and technical terminology.
Procedure: The examination is conducted in the classroom at the end of the course.
Duration: Approximately 2 hours.
Format: Open-ended questions and multiple-choice questions.
Evaluation: The final grade is expressed on a 30-point scale and is based on the accuracy of the content, the ability to provide reasoned answers, and clarity of exposition.

Example exam questions

Module 1 – Applied Dietetic Sciences for Energy Requirements:
Describe the main components of energy expenditure and the methods used to estimate individual energy requirements.
Module 2 – Applied Dietetic Sciences for Nutrient Requirements:
Explain the requirements for macronutrients and micronutrients, the main factors influencing them, and the role of reference intake values in the assessment of nutritional adequacy.
Module 3 – Applied Dietetic Sciences for Nutritional Status Assessment:
Describe the main tools and indicators used for the assessment of nutritional status and their integration in the interpretation of an individual's nutritional profile.
