Nutraceuticals and botanicals: overview and perspectives

The discovery, development and marketing of food supplements, nutraceuticals and related products are currently the fastest growing segments of the food industry. Functional foods can be considered part or borderline to these products and may be defined as foods or food ingredients that have additional health or physiological benefits over and above the normal nutritional value they provide. This trend is driven by several factors, mainly due to the current consumer perceptions: the first and dominant being ‘Natural is good’, and other secondary, such as the increasing cost of many pharmaceuticals and their negative secondary effects, the insistent marketing campaign, the increasing perception of the need of a healthy diet and its importance in the health and homeostasis organism conditions. However, the central point is that nutraceuticals, botanicals and other herbal remedies, including the entry of new functional foods, are important because of their acceptance as the novel and modern forms to benefit of natural substances. Due to the rapid expansion in this area, the development of several aspects is considered as it could influence the future of the market of these products negatively: an imbalance existing between the increasing number of claims and products on the one hand, the development of policies to regulate their application and safety on the other, rapid and valuable controls to check the composition, including the plant extracts or adulteration to improve efficacy, like the presence of synthetic drugs. It is interesting to see that, from the negative factors reported by the market analysts, a change in consumers preferences is absent. The functional properties of many plant extracts, in particular, are being investigated for potential use as novel nutraceuticals and functional foods. Although the availability of scientific data is rapidly improving, the central aspect concerns the validation of these products. The first step of this crucial aspect is the security of the composition, obtained by the useful and adapted analytical approach. On the other hand, in the first instance, security is assured by the millenary use as food of the great majority of these plants. The importance and the novelty of functional food are inherent in the possibility to renew the secure use of plants to maintain healthiness of man in novel forms of use adapted to modern times. The market of ‘other substances’, after the emergence of the first period of enthusiastic explosion, is entering into the maturation period, with three important arguments to face: (a) security in composition, production and sale, avoiding easy conversions or convenient approaches and favouring competence and professionalism, (b) definition of influence of metabolic aspects, including scientific validation and (c) regulatory aspects, e.g. the claims definition and relative influences. The last aspect seams to be in primis the most crucial and fundamental to the future of all the sectors. The role of European Food and Safety Authority (EFSA) in the EU market must be considered and consequences if negative decisions on ‘other substances’ claim will be adopted in each country's legislation.
