Nutritional prevention of chronic diseases : from research to public health action

Nutrition is now recognized as one of the major determinants of health. It encompasses a range of modifiable risk and protective factors, all of which can be leveraged at individual and collective level to improve the health of populations and help reduce social inequalities. This series of conferences addresses current concepts and issues in public health nutrition : How are levels of evidence established ? What scientific contributions have been made by the major French epidemiological studies of recent decades ? Beyond established knowledge (on alcohol, salt, fiber, etc.), many questions remain as to the impact of emerging risk factors (industrial or domestic transformation processes, food additive mixtures, pesticide residues, fasting, dietary supplements, etc.) on the long-term health of mankind and the planet. How can we sort out the real from the fake, between real scientific knowledge and " fake news ", in a field that is the subject of much ink and of major economic interests? Once the nutritional factors and behaviors to be promoted or avoided have been identified, how can they be monitored at population level, and what public health measures (labeling, pricing policies, regulation of advertising, etc.) can be put in place to effectively improve chronic disease prevention ?
