The power of plants: how fruit and vegetables work as source of nutraceuticals and supplements

Abstract

Plants are a rich source of nutraceuticals/supplements/phytonutrients/secondary metabolites. There are many industries, health care systems and academic activities involved in their use and promotion. However, many of these key players are peripherally involved in the science and policy behind their production, processing and utilisation. Here we will explore some key concepts related to the science and innovative strategies on the use of plants and their bioactive compounds for promoting human health and fight chronic diseases. Knowledge of how bioactive compounds are biosynthesized in the plant under different stress conditions and their mode of action against chronic diseases are key elements needed for an effective use of plant bioactives or nutraceuticals. This information can be the basis for developing preventive and therapeutic nutraceuticals to promote human health and could open opportunities for consumers to access low cost-effective use of plants as medicine, revalue crops, create new products and open new markets.

Keywords: Plants; chronic diseases; oxidative stress; preventive and therapeutic nutraceuticals; promoting human health; secondary metabolite biosynthesis; supplements.
