Nutraceuticals and Functional Foods: Is It Possible and Sustainable for Bridging Health and Food?

This editorial is part of the Special Issue entitled “Nutraceuticals and Functional Foods: Bridging Health and Food Under a New Perspective”. Current state-of-the-art research on nutraceuticals and functional foods is focusing on the recovery and re-use of bioactive substances from vegetal or animal byproducts. The following aspects of this research must be considered: (i) low environmental impact; (ii) safety of novel extraction strategies; and (iii) new sources (e.g., byproducts from the agro-food area) and new methodologies. Moreover, the byproducts deriving from transformation and manufacturing in the agro-food industry, which are often disposed of or used as feed, must adhere to good manufacturing practices and procedures.
