    Functional Foods and Lifestyle Approaches for Diabetes Prevention and Management
    (MDPI, 2017-12-01) Alkhatib, Ahmad; Tsang, Catherine; Tiss, Ali; Bahorun, Theeshan; Arefanian, Hossein; Barake, Roula; Khadir, Abdelkrim; Tuomilehto, Jaakko
    Functional foods contain biologically active ingredients associated with physiological health benefits for preventing and managing chronic diseases, such as type 2 diabetes mellitus (T2DM). A regular consumption of functional foods may be associated with enhanced anti-oxidant, anti-inflammatory, insulin sensitivity, and anti-cholesterol functions, which are considered integral to prevent and manage T2DM. Components of the Mediterranean diet (MD)—such as fruits, vegetables, oily fish, olive oil, and tree nuts—serve as a model for functional foods based on their natural contents of nutraceuticals, including polyphenols, terpenoids, flavonoids, alkaloids, sterols, pigments, and unsaturated fatty acids. Polyphenols within MD and polyphenol-rich herbs—such as coffee, green tea, black tea, and yerba maté—have shown clinically-meaningful benefits on metabolic and microvascular activities, cholesterol and fasting glucose lowering, and anti-inflammation and anti-oxidation in high-risk and T2DM patients. However, combining exercise with functional food consumption can trigger and augment several metabolic and cardiovascular protective benefits, but it is under-investigated in people with T2DM and bariatric surgery patients. Detecting functional food benefits can now rely on an “omics” biological profiling of individuals’ molecular, genetics, transcriptomics, proteomics, and metabolomics, but is under-investigated in multi-component interventions. A personalized approach for preventing and managing T2DM should consider biological and behavioral models, and embed nutrition education as part of lifestyle diabetes prevention studies. Functional foods may provide additional benefits in such an approach.

    Adherence rates to the Mediterranean diet are low in a representative sample of Greek children and adolescents
    (Oxford University Press, 2008-10-01) Kontogianni, Meropi D.; Vidra, Nikoletta; Farmaki, Anastasia-Eleni; Koinaki, Stella; Belogianni, Katerina; Sofrona, Stavroula; Magkanari, Flora; Yannakoulia, Mary
    Data from studies in pediatric samples exploring adherence to the Mediterranean diet are scarce. The aim of the present work was to explore adherence to a Mediterranean diet pattern in a representative sample of Greek children and adolescents. The study sample (n = 1305, 3–18 y) was representative of the Greek pediatric population in terms of sex and age. Information on participants' sociodemographic, anthropometric, and lifestyle characteristics were collected through telephone interviews. Adherence to the Mediterranean diet guidelines for adults and to the general dietary guidelines for children was evaluated using KIDMED scores: the higher the score, the more favorable the dietary pattern. The Goldberg cut-off limits for the ratio of energy intake:basal metabolic rate were used to evaluate dietary underreporting and children were accordingly classified as low energy reporters (LER) or non-LER. Only 11.3% of children and 8.3% of adolescents had an optimal KIDMED score (≥8). In adolescents, partial correlation analysis revealed a negative weak association between KIDMED and BMI (r = −0.092; P = 0.031), which remained significant in the non-LER subgroup (r = −0.137, P = 0.011). Multiple regression analysis revealed that higher KIDMED scores were associated, in non-LER children, with less time spent on sedentary activities (P = 0.002) and higher paternal education (P = 0.050), whereas in adolescents, with younger age (P = 0.001), less time spent on sedentary activities (P = 0.015), higher maternal education (P = 0.014), and higher eating frequency (P = 0.041). In conclusion, low adherence rates to the Mediterranean diet were observed in Greek children and adolescents; this evidence needs to be further explored regarding its impact on health and disease.
