The Potential Health Benefits of Polyphenol-Rich Extracts from Cichorium intybus

Phytochemicals can exert their bioactivity without reaching the systemic circulation; scarcely absorbed antioxidants might reach the large bowel contributing to protection from oxidative damage-induced gastrointestinal diseases. In the present work, we aimed to study the relationship between potential activity of polyphenol-rich extracts from Cichorium intybus L. and changes in morphological characteristics on Caco-2 cells. Phytochemicals content (carotenoids and flavonoids) and total antioxidant activity of Red Chicory of Treviso and Variegated Chicory of Castelfranco were evaluated. The bioactivity of polyphenol-rich extracts from chicories was studied in in vitro Caco-2 cell monolayers model. Morphological characteristics changes to test the antioxidant and/or prooxidant effect were verified by histological analysis and observed by Electronic Scansion Microscopy (SEM). On Caco-2 cell model, the polyphenols fractions from chicories have indicated a moderate antioxidant behavior until 17 μM concentration, while 70 μM and 34 μM exert cytotoxic effects for Treviso’s and Castelfranco’s Chicory, respectively, highlighted by TEER decreasing, increased permeability, and alteration of epithelium. Our findings support the beneficial effects of these products in counteracting the oxidative stress and cellular damage, induced in vitro on Caco-2 cell model, through interaction with the mucopolysaccharide complexes in the glycocalyx, maintaining in vivo a healthy and effective intestinal barrier

Migration as Cultural Phenomenon in a Globalized World: A Pilot Study on Lifestyle and Eating Behaviours of Adolescents Living in Rome

The aim of this research was to assess, through an observational study, lifestyle and eating behaviours of adolescents (native, and first- and second-generation immigrants), in order to understand if the migration process may have influenced these aspects. The study was carried out by a structured questionnaire packet that investigated anthropometric data, eating habits, smoking, alcohol consumption, physical activity, and sedentary behaviours. A total of 105 respondents, aged 10–24 years (51.4% first-generation immigrants, 19.1% second-generation immigrants, and 29.5% natives) were included in the study. The results showed statistical differences in some social aspects by migration status, such as place of residence, living arrangement, parental educational level, and eating differently from family members. Despite these differences, volunteers were perfectly integrated regarding most eating habits and lifestyle behaviour, underlying a process of acculturation. Moreover, our study indicates the existence of inadequate dietary habits, such as skipping breakfast. It is important to implement effective nutrition interventions for adolescents to promote healthier lifestyle choices, considering that they should also include cultural components of dietary habits

Mediterranean Diet Adherence in Adolescents of Different Cultures and Geographical Proveniences: A Pilot Study

The objective of the present research was to evaluate if and to what extent the encounter between different cultures in a context of globalization may have influenced the adherence to the Mediterranean diet (MD) in adolescents. The study comprised a structured questionnaire packet that inquired about anthropometric data, demographic information and both dietary and lifestyle habits. The KIDMED questionnaire was used to evaluate the adherence to the MD. A total of 103 respondents, aged 10–24 years (39.8% born in Italy or first-generation immigrants from Mediterranean countries) were included in the study. The results showed the highest percentage of adolescents having a medium adherence to the MD (44.7%), without differences according to geographical area of origin. Furthermore, the study proved that a higher adherence to the MD was significantly associated with daily breakfast (p = 0.008) and the consumption of fruit and vegetables (p = 0.002 and p = 0.000, respectively). Volunteers representing some of the different cultures and geographical proveniences currently present in Italy were perfectly integrated regarding diet and lifestyle, aspects considered in this study. Our investigation suggests the existence of incorrect dietary habits. It is certainly necessary to implement public health policies targeting adolescents to promote healthier lifestyle choices; the nutritional patterns of the MD should be among these choices

Total and Plant Protein Consumption: The Role of Inflammation and Risk of Non-Communicable Disease

Background: Inflammatory cytokine levels are associated with Non-Communicable Diseases (NCDs) and can be influenced by a person’s macronutrient profile. This work aims to evaluate the relationship between the compliance with the age-specific recommended protein intake and the levels of inflammatory markers related to the risk of NCDs. Methods: The study participants included 347 participants (119 men and 228 women), ages 18 to 86 years. Cardio-metabolic risk evaluations, including an assessment of the prevalence of Metabolic Syndrome, were performed. Leptin, IL-15, IL-6, and TNF-α levels were measured. Results: The adequacy of the total protein (TP) intake was lower in old people compared to individuals aged <60 years, and only few volunteers consumed the suggested 50% plant protein (PP) for a healthy and sustainable diet. A lower risk of NCDs with a PP consumption above at least 40% was observed only in old individuals. A differential effect on TNF-α and IL-6 was observed for both TP and PP intake by gender and age class, whereas for leptin and IL-15 only significant interactions among sex and the class of age were found. Conclusion: Although our data suggest that consuming more than 40% of PP can reduce the risk of NCDs, the effect of gender differences on cytokine levels should be considered in larger studies
