Academic Year 2024/2025

  • Teaching Mode: Traditional lectures
  • Campus: Rimini
  • Corso: Second cycle degree programme (LM) in Human Nutrition, Well-Being And Health (cod. 5812)

Learning outcomes

At the end of the course the student: - knows the basic elements on the biochemical role and the mechanism of action at the cellular, molecular, metabolic, genetic and epigenetic level of the nutraceutical components contained in food. - will be able to understand the rationale for using the main nutraceuticals in the protection / prevention of chronic degenerative diseases. - is able to communicate the optimal use of nutraceuticals within the framework of the guidelines for proper nutrition.

Readings/Bibliography

Lecture notes in the form of a pdf file and scientific papers.

Nutraceuticals: Efficacy, Safety and Toxicity. Ramesh C. Gupta, Academic Press 2021

Selected paper published on Scientific Journals

Teaching methods

The course will be delivered through lectures, supported by PowerPoint presentations to enhance comprehension of the topics covered.

To facilitate learning and further study, the following educational materials will be made available on the virtual learning platform:

  • PDF presentations, specifically prepared by the instructor, containing explanatory text and provided both before and during the lectures.
  • Scientific articles from open-access journals, offering up-to-date evidence to supplement course content.
  • Recorded video lectures using the Panopto system, accessible after each session and available throughout the Academic Year on the virtual platform.


In particular, the use of the lessons in asynchronous mode will allow students to prepare themselves for the exam, possibly with the remote supervision of the teacher.

The teaching participates in the University's educational innovation project.

Assessment methods

The examination at the end of the course aims to assess the achievement of learning objectives:
- to know the main nutraceuticals in food and mechanism of action
- to know the role of nutraceutical compounds in the prevention of chronic/degenerative diseases

- to know the rationale and evidence to use nutraceuticals, and to correctly communicate their use

The final exam consists of a written test structured into two sections:

  1. Multiple-choice questions: The test includes 18 questions, each with four answer options, only one of which is correct. Each correct answer is worth 1 point, while incorrect or unanswered questions do not incur penalties.

  2. Open-ended questions: There are 2 open-ended questions, each graded on a scale from 0 to 6 points, based on the completeness, accuracy, and depth of the response.

The final score of the written test, expressed in thirtieths (out of 30), is determined by summing the points obtained from the multiple-choice and open-ended questions.

Optional Task – Nutraceutical Intervention Plan

In addition to the written exam, students may choose to complete an optional task, which involves designing a nutraceutical intervention plan aimed at maintaining the health status of a model subject assigned by the professor. This task will be evaluated on a scale of 0 to 2 points, which will be added to the final written exam score.

The maximum possible score, considering both the written test and the optional task, is 32/30, allowing for the possible awarding of honors (lode) if the total score exceeds 30/30.
