Learning objectives
Aims of the course are: (i) the understanding of how a correct nutritional state is important in order to assure an optimal health state and to compensate the energy expenditure related physical activity; (ii) the knowledge of principles at the basis of an optimal and healthy diet according to scientific national (LARN and National guidelines) and international guidelines (EFSA) and to deal with physical and sport activity; (iii) the knowledge of the features and properties of the various nutrients required in a balanced diet; (iv) the knowledge and understanding of the concepts and procedures of statistics applied to biomedical sciences, including hypothesis testing in the analysis of continuous and categorical variables, correlation and regression.
Expected learning outcomes
At the end of the course, students should know principles for defining a dietary scheme and to critically analyze some of the most common dietary regimes. Through specific practical exercises, students should have become able to know and select most appropriate sources of energetic nutrients and their best assortment to compose diets suited for specific type of physical activities and sports. Students should have become able to know pros and cons of dietary supplements. Moreover, students are expected to become able to know the usefulness of linear and non-linear regression and how to apply it to generate predictive models. By means of examples of application of statistics to nutritional topics, students should have become able to interpret the results of statistical analyses published in the biomedical literature, and should have acquired the ability to select the best statistical approach to analyze different datasets.

First semester
Prerequisites for admission
For Biology of nutrition module the knowledge of biochemistry, biochemistry of nutrition and physiology of nutrition is required
For the Data analysis and predictive modeling module no prerequisite knowledge is required
Assessment methods and Criteria
For Biology of nutrition module the verification of students' preparation is in form of an oral test. During the oral examination, open questions about the basic nutrition and the nutrition topics for physical activity and sport will be done. Exercises on diet planning may also be required. The expected duration of the test is 30 minutes. The evaluation expressed in thirtieths is the result of both the knowledge of the topics covered and the student's critical analysis ability. The score of 30/30 cum laude is assigned in case of excellent mastery of both factors mentioned.
for the Data analysis and predictive modeling module the verification of the students' preparation consists of a written, multiple-choice test comprising 31 questions. The duration of the test is 60 minutes. The evaluation is given according to the following scoring system: 31 correct answers, 30/30 e lode; 30 correct answers, 30/30; 29 correct answers, 29/30; and so on.
The final score is the weighted average of the individual marks relating to the credits of the two modules.
The individual marks as well as the weighted average are published on ARIEL within 24-48 hours from the completion of the exam.
