Nutritional Epidemiology: Summary Methods and Results from Ongoing Cohorts and Future Perspectives

Over the last 40 years, nutritional epidemiology has provided crucial evidence on the role of dietary factors toward human health. Current guidelines are based on corroborated data from cohort studies; although they are only observational, findings from high-quality cohorts may provide adequate evidence for the association between dietary exposure and occurrence of disease (or preservation of good health). Compared to drugs, dietary factors physiologically occur in human life; thus, they rarely exert a direct causal effect on health. Rather, they affect the risk in the context of complicated pathways. Nonetheless, a combination of “healthy” or “unhealthy” behaviors has been widely accepted as a risk modulator, and results from cohorts studies have been used to address guidelines or mere recommendations to the public. 

The aim of this Special Issue is to collect a summary of the main results (or grouped by outcomes) of ongoing or concluded cohort studies in order to provide an overview of what has been done and what would be the future plans to better understand the relation between nutritional risks and human health. Reviews on methods (i.e., data collections and statistical inference) are also welcome to collect important sources of information which is potentially useful when it comes to planning future studies.
