The molecular mechanism of the cholesterol-lowering effect of dill and kale: The influence of the food matrix components.

Foods are complex matrices containing many different compounds, all of which contribute to the overall effect of the food itself, although they have different mechanisms of action. While evaluating the effect of bioactive compounds, it is important to consider that the use of a single compound can hide the effects of the other molecules that can act synergistically or antagonistically in the same food. The aim of the present study was to evaluate the influence of food matrix components by comparing two edible plants (dill and kale) with cholesterol-lowering potential and similar contents of their most representative bioactive, quercetin.

Mixed pro- and anti-oxidative effects of pomegranate polyphenols in cultured cells.

In recent years, the number of scientific papers concerning pomegranate (Punica granatum L.) and its health properties has increased greatly, and there is great potential for the use of bioactive-rich pomegranate extracts as ingredients in functional foods and nutraceuticals. To translate this potential into effective strategies it is essential to further elucidate the mechanisms of the reported bioactivity.

Traditional foods for health: screening of the antioxidant capacity and phenolic content of selected Black Sea area local foods.

Background: The nutritional characteristics of the Black Sea area (BSA) traditional foods are almost unknown, and they could be interesting sources of antioxidant compounds. In this study, carried out within the BaSeFood project, the in vitro total antioxidant capacity (TAC) and phenolic content of 39 BSA traditional foods were determined using different assays.

Results: An ample range of TAC and phenolics content was detected in the examined foods that were ranked according to their scavenging activity expressed per weight unit and per serving size.

Rocket salad (Diplotaxis and Eruca spp.) sensory analysis and relation with glucosinolate and phenolic content.

Background: Salad crops of the Brassicaceae family, such as Diplotaxis tenuifolia and Eruca vesicaria, commonly referred to as 'rocket salads', have attracted considerable interest as culinary vegetables because of their strong flavour and their content of putative health-promoting compounds. Among such compounds, glucosinolates and phenolics are well-known phytochemicals with an important role also in determining the characteristic flavour of these species. In this study, to identify potentially high-value rocket salads, 37 cultivated types were examined for sensory characters and their relations with glucosinolate and phenolic contents, which ranged from 0.
