LLEK10249U Evidence, Diet and Health

Volume 2020/2021

MSc Programme in Clinical Nutrition
MSc Programme in Human Nutrition


The focus of the course is how to assess available evidence for a causal relationship between diet and diseases with a main focus on diet, macronutrients and life-style diseases such as cancer, type 2 diabetes, and cardiovascular disease. The course will provide the students with theoretical teaching in the methodology, several examples and exercises and assignments that gives them opportunity to practise.

Learning Outcome

The main objective of the course is to provide the students with an understanding of basic methods and concepts in nutritional epidemiology, to enable them to assess available evidence for a causal relationship between diet and diseases.

After completion of the course the students should be able to:

- Define epidemiology and causality
- Describe the epidemiological measures of frequency and association
- Explain the concepts bias, confounding, effect modification, chance, power, validity and generalisability
- List the study designs, and describe their advantages and limitations in relation to nutritional epidemiology
- Describe the structure of a data set, and types of variables

- Demonstrate ability to critically assess the validity of studies on the relation between diet and disease
- Demonstrate ability to handle a data set with nutritional variables, and to assess for confounding and effect modification
- Discuss the evidence for causal relationship between diet and disease

- Independently perform evidence evaluations of relationships between dietary components and health
- Identify gabs in our current knowledge and to contribute to the planning of studies that will make progress
- Make dietary recommendations based on an evaluation of the evidence

Course literature will be announced at study start on the course’s Absalon page.

Academic qualifications equivalent to a BSc degree are recommended.
Knowledge and skills in nutrition, physiology, biochemistry, and statistics are recommended.
Theoretical lectures and exercise practice. The objective of course assignments is to use of the principles in evaluation of scientific evidence.
