Abstract: The study provides original data on the compositional profile (macronutrients, dietary fiber, mineral and trace elements, bioactive molecules) of an Italian typical plant foods, Treviso Red Cichory, studying the two cultivars (Early, Late) grown following two different traditional cultivation systems. For two consecutive years plants from three growing areas, were studied. Major, significant differences, between Early and Late cultivars, were observed in minerals (Ca, Mg, P), trace elements (Fe, Zn) and bioactive molecules content. The Late cv. was found the richest in minerals and trace elements content than the Early cv., but for Ca. Treviso Red Cichory was found a valuable source of bioactive molecules such as ascorbic acid, anthocyanins and total polyphenols. The Early cv. showed a significantly higher (p < 0.05) ascorbic acid and total anthocyanins content (8.63 and 92.15 mg/100g, respectively) than the Late cv. (6.15 and 24.38 mg/100g, respectively), by contrast total polyphenols content was significantly higher (p < 0.05) in the Late cv. A marked variability in bioactive molecules content among the growing areas was found only for the Late cv. The observed differences between the

Abstract: Wild rocket [ Diplotaxis tenuifolia (L.) DC.] belongs to the Brassicaceae family and has its origin in the Mediterranean region. The effect of conventional and integrated cultivation practices on the nutritional properties and benefits of wild rocket [ Diplotaxis tenuifolia (L.) DC.] were studied. Bioactive molecules content (vitamin C, quercetin, lutein), antioxidant properties and bioactivity of polyphenolic extracts from the edible part of rocket in Caco-2 cells were determined. Regarding antioxidant properties, FRAP (Ferric Reducing Antioxidant Power) values ranged from 4.44 ± 0.11 mmol/kg fw to 9.92 ± 0.46 mmol/kg fw for conventional rocket and from 4.13 ± 0.17 fw mmol/kg to 11.02 ± 0.45 mmol/kg fw for integrated rocket. The characteristics of wild rocket as a dietary source of antioxidants have been pointed out. Significant differences in the quality of conventional and integrated rocket have been shown, while no influence of agronomic practice on biological activity was reported. A significant accumulation of cells in G1 phase and a consequent reduction in the S and G2 + M phases were observed in Caco-2 cells treated with rocket polyphenol extract.

Abstract: An observational study was conducted on 131 healthy free-living subjects. Dietary intake was assessed by dietary diary. Standardised procedures were used to make anthropometric measurements. On blood samples (serum, plasma and whole blood) were evaluated: antioxidant status by vitamin A, vitamin E, carotenoids, vitamin C, uric acid, SH groups, SOD and GPx activities; lipid blood profile by total cholesterol, HDL cholesterol, LDL cholesterol, triglycerides; total antioxidant capacity by FRAP and TRAP; the immune status by TNF-α, and IL-10 cytokines; the levels of malondialdehyde in the erythrocytes as marker of lipid peroxidation.The daily macronutrients intake (g/day) have shown a high lipids consumption and significant differences between the sexes with regard to daily micronutrients intake. On total sample mean Mediterranean Diet Score (MDS) was 4.5 ± 1.6 and no significant differences between the sexes were present. A greater adherence to a Mediterranean dietary pattern increases the circulating plasma levels of carotenoids (lutein plus zeaxanthin, cryptoxanthin, α and β-carotene), vitamin A and vitamin E. The levels of endogenous antioxidants were also improved. We observed higher levels in anti-inflammatory effect cytokines (IL-10) in subjects with MDS ≥ 6, by contrast, subjects with MDS ≤ 3 show higher levels in sense of proinflammatory (TNF α P < 0.05). Lower levels of MDA were associated with MDS > 4. Our data suggest a protective role of vitamin A against chronic inflammatory conditions especially in subjects with the highest adherence to the Mediterranean-type dietary pattern.Mediterranean dietary pattern is associated with significant amelioration of multiple risk factors, including a better cardiovascular risk profile, reduced oxidative stress and modulation of inflammation.The Mediterranean Diet (MD), a nutritional model inspired by the traditional food regimes of countries in the Mediterranean basin, including Italy, Greece, Spain and Morocco, has ente

Abstract: The artichoke ( Cynara cardunculus L. subsp. scolymus L.), the cultivated cardoon ( Cynara cardunculus var. altilis DC.) and the wild cardoon ( Cynara cardunculus var. sylvestris L.) are species widely distributed in the Mediterranean area. The aim of this research was to evaluate the antioxidant properties of seeds from lines of artichoke and cultivated and wild cardoon in both aqueous-organic extracts and their residues by FRAP (Ferric Reducing Antioxidant Power) and TEAC (Trolox Equivalent Antioxidant Capacity) evaluations. Both artichoke and cardoon seeds are a good source of antioxidants. Among artichoke seeds, hydrolysable polyphenols contribution to antioxidant properties ranged from 41% to 78% for FRAP values and from 17% to 37% for TEAC values. No difference between cultivated and wild cardoon in antioxidant properties are reported. Our results could provide information about the potential industrial use and application of artichoke and/or cardoon seeds.
