Special Issue Information

Dear Colleagues,

Metabolic Syndrome and Type 2 Diabetes are the major causes of morbidity and mortality in the elderly, with an increasing prevalence worldwide. These disorders cause micro-and macrovascular damage, leading to consequences, such as CAD, ischemia, heart failure, stroke, neuronal disturbances, reproductive and joint diseases, and other syndromes characterized by dysregulated inflammatory processes, and degradation of tissue function. Despite numerous recommendations emphasizing lifestyle changes, pharmacotherapy is also essential in the prevention and treatment of these syndromes, especially in more severe or chronic cases.

Bioactive compounds (phytonutrients or functional foods) have been defined as the extra nutritional constituents that are derived from natural products in small quantities. These molecules are mainly phytochemicals that can modulate metabolic processes, resulting in the promotion of better health. The bioaccessibility and bioavailability of each bioactive compound differs greatly, since several bioactive plant compounds are produced as secondary metabolites that are not essential for the daily functioning of the plant (such as growth), but play a significant role in competition, defense, attraction and signaling. Bioactive compounds in the plants can be specified as secondary plant metabolites eliciting pharmacological or toxicological effects in humans and animals. They include various molecules such as flavonoids, carotenoids, carnitine, choline, coenzyme Q, creatine, dithiolthiones, phytosterols, polysaccharides, phytoestrogens, glucosinolates, polyphenols, anthocyanins, prebiotics, and taurine.

This special issue aims to bring together food chemistry, food technology (with analysis or characterization of natural compounds) in medical interest and nutraceutical researches (for diet therapy and cosmetics) to identify and discuss cutting-edge research on novel ways in the treatment of Metabolic Syndrome and Type 2 Diabetes.

Diabetes mellitus (DM) and consequential cardiovascular diseases lead to millions of deaths worldwide each year; 90% of all people suffering from DM are classified as Type 2 DM (T2DM) patients. T2DM is linked to insulin resistance and a loss of insulin sensitivity. It leads to a reduced uptake of glucose mediated by glucose transporter 4 (GLUT4) in muscle and adipose tissue, and finally hyperglycemia. Using a fluorescence microscopy-based screening assay we searched for herbal extracts that induce GLUT4 translocation in the absence of insulin, and confirmed their activity in chick embryos. We found that extracts prepared from Bellis perennis (common daisy) are efficient inducers of GLUT4 translocation in the applied in vitro cell system. In addition, these extracts also led to reduced blood glucose levels in chicken embryos (in ovo), confirming their activity in a living organism. Using high-performance liquid chromtaography (HPLC) analysis, we identified and quantified numerous polyphenolic compounds including apigenin glycosides, quercitrin and chlorogenic acid, which potentially contribute to the induction of GLUT4 translocation. In conclusion, Bellis perennis extracts reduce blood glucose levels and are therefore suitable candidates for application in food supplements for the prevention and accompanying therapy of T2DM.

Metabolic illnesses such as non-alcoholic fatty liver disease (NAFLD) are in constant increase worldwide. Highly consumed long chain fatty acids (LCFA) are among the most obesogenic and steatogenic nutrients. Hepatic steatosis is associated with several complications such as insulin resistance. Growing evidence points to medium chain fatty acids (MCFA), more efficiently oxidized than LCFA, as a promising dietary alternative against NAFLD. However, reports on the hepatic effects of MCFA are sometimes conflicting. In this study we exposed HepG2 cells, a human hepatocellular model, to 0.25 mM of hexanoic (C6), or octanoic (C8), and decanoic (C10) acids separately or in a C8 + C10 equimolar mix reflecting commercially available MCFA-rich oils. We found that C6, a poorly studied MCFA, as well as C8 and C10 did not provoke the deleterious lipid anabolism runaway typically induced by LCFA palmitate. MCFA tended, instead, to promote a balanced metabolic profile and were generally non-cytotoxic. Accordingly, mitochondrial integrity was mostly preserved following MCFA treatment. However, treatments with C8 induced a mitochondrial membrane potential decrease, suggesting prolonged exposure to this lipid could be problematic. Finally, MCFA treatments maintained optimal insulin sensitivity and even fostered basal and insulin-dependent phosphorylation of the Akt-mTOR pathway. Overall, MCFA could constitute an effective nutritional tool to manage liver steatosis and hepatic insulin resistance. Full article
