Biology of Nutrition
A.Y. 2019/2020
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.

Prerequisites for admission
For Biology of nutrition module it is recommended to have acquired skills in biochemistry, biochemistry of nutrition, physiology of nutrition
For Data analysis and predictive modeling module knowledge of basic maths principles is recommended
For Data analysis and predictive modeling module knowledge of basic maths principles is recommended
Assessment methods and Criteria
For Biology of nutrition module the verification of student preparation is in form of a written test followed by an oral test. The written test (30% of the final grade) consists of an open question on nutrition biology topics for physical activity and sport. The expected duration of the test is 30 minutes. The oral exam (70% of the final grade) will focus on all the topics covered during the lessons in classroom
for the Data analysis and predictive modeling module is a written test, consisting of a series of problems covering the topics explained during the course. The expected duration of the test is three hours
The final score is the weighted average of the individual marks relating to the credits of the two modules

Course syllabus
The principal topics of the course are illustrated in the followimgs:
Structure of a scientific paper and role of data analysis.
Descriptive statistics: tables, graphical plots, summary measures of central tendency and variability (mean, variance, standard deviation, median, percentiles, quartiles).
The Gaussian (a.k.a, Normal) distribution.
Basic concepts of inferential statistics
Hypothesis testing and statistical significance. Statistical errors of the first and second type.
How to compare a mean against a reference value: one-sample z test and t test
How to compare two means:
How to compare three or more means: the F distribution and ANOVA.
How to manage situations in which the data distribution is not normal: introduction to nonparametric statistics.
How to analyze the relationship between two variables by means of correlation analysis.
Predictive modelling: linear and nonlinear regression.
Categorical data analysis: the chi squared test.
The software R: fundamentals of programming and statistical analysis
