Abstract

Food supplies energy, nutrients, and different types of molecules and even micro-organisms that play key roles in human body. In addition, food also conveys pleasure and it is entangled with social behaviours and beliefs. Besides the macronutrients, the relevance of other compounds has been disclosed, notably about polyphenols. Besides the macronutrients, the relevance of other compounds has been disclosed, notably about polyphenols. This family of molecules has been regarded as unpleasant for their bitter taste, astringency or darkening of juices by food technologists. Polyphenols have also been regarded as antinutrients because of their ability to bind minerals and to denature proteins. However, recently many health-promoting properties have been attributed to polyphenols and a new niche market of food supplements is on the rise. On the other hand, the Med Diet contains a wide variety of ingredients rich in phytonutrients and it also encompasses cooking methods that optimize the interaction and protection of such phytonutrients. The present chapter focuses on polyphenol-rich foods of Med Diet and the interactions between them.

    Ultraprocessed foods can be defined as industrial products containing more than 4–5 ingredients that may include additives, hydrolyzed proteins, modified starches, emulsifiers, hydrolyzed fats (and trans-fats) as well as flavour enhancers. Such products are generally dense in calories, nutritionally poor and with excessive levels of simple sugars (e.g. glucose, sucrose), fats, salt and other health-deleterious compounds.
