EN The bioactive compounds and elements, as the name implies (the Greek “bios” means life, and the Latin “activus” means dynamic or full of energy), are characterized by a certain biological activity that has a direct impact on the living organisms. The interaction can have a positive or negative effect, depending on the nature of the substance, its dose, and bioavailability. The bioactive compounds can act as antioxidants, enzyme inhibitors and inducers, inhibitors of receptor activities, and inducers and inhibitors of gene expression, among other actions. The essential trace elements play a vital role in many biochemical reactions and are important building blocks of some enzymes and proteins. Nevertheless, although the bioactive components of the human diet are not those necessary to meet the basic nutritional needs as the nutrients do, they still play an important role in human nutrition.
