SCOPE: Buckwheat (BW) consumption has been associated to a broad range of health benefits: antioxidant, anti-inflammatory and anticancer. These beneficial effects have been partially related to the presence of flavonoids. However, some of these compounds (i.e., rutin and quercetin) are metabolized in the gastrointestinal tract generating derived phenolic metabolites. In this study we investigated the biological activity of rutin (Ru), quercetin (Q) an their derived phenolic metabolites 3,4-dihydroxyphenylacetic acid (3,4-DHPAA), 3-hydroxyphenylacetic acid (3-HPAA), and 4-hydroxy-3-methoxyphenylacetic acid (homovanillic acid, HVA)...

SCOPE: This study was designed to determine whether irisolidone and its glycoside kakkalide, which are the major constituents of the flower of Pueraria lobata (Kudzu) can attenuate ethanol-induced gastritic injury in mice. METHODS AND RESULTS: Irisolidone and kakkalide inhibited IL-8 secretion and NF-κB activation in lipopolysaccharide-stimulated KATO III cells. Therefore, we investigated their protective effects against ethanol-induced gastric injury in mice. Pretreatment with kakkalide or irisolidone decreased the area of hemorrhagic ulcerative lesions caused by ethanol and suppressed stomach myeloperoxidase activity, CXCL4 secretion, and NF-κB activation...

Bioactive compounds in plant-based foods have health properties that contribute to the prevention of age-related chronic diseases, particularly cardiometabolic disorders. Conclusive proof and understanding of these benefits in humans is essential in order to provide effective dietary recommendations but, so far, the evidence obtained from human intervention trials is limited and contradictory. This is partly due to differences between individuals in the absorption, distribution, metabolism and excretion of bioactive compounds, as well as to heterogeneity in their biological response regarding cardiometabolic health outcomes...

The aim of this review is to summarize the relevant literature about the use of canthaxanthin in food science and nutrition research. Canthaxanthin is a red-orange carotenoid that belongs to the xanthophyll group. This naturally occurring pigment is present in bacteria, algae and some fungi. Canthaxanthin is also responsible for the color of flamingo feathers, koi carp skin and crustacean shells. Canthaxanthin is widely used in poultry (broiler, laying hens) as a feed additive. Canthaxanthin can be obtained by total synthesis...

SCOPE: MFD, a diet based on multiple functional concepts and ingredients with antiinflammatory activity, was previously shown to improve different cardiometabolic risk-associated markers in healthy subjects. Here, we assessed the impact of MFD on plasma metabolome and explored associations of the differential metabolites with clinical parameters, searching for metabolic determinants related to the effects of MFD. METHODS AND RESULTS: Forty-four overweight healthy volunteers completed a randomized crossover intervention comparing MFD with a control diet devoid of the active components of MFD...

Promoting the development of brown or beige adipose tissue may protect against obesity and related metabolic features, and potentially underlies protective effects of genistein in mice. We observed that application of genistein to 3T3-L1 adipocytes changed the lipid distribution from large droplets to a multilocular distribution, reduced mRNAs indicative of white adipocytes (ACC, Fasn, Fabp4, HSL, chemerin and resistin) and increased mRNAs that are a characteristic feature of brown/beige adipocytes (CD-137 and UCP1)...

SCOPE: Silicon is one of the most abundant trace elements in the body. Although pharmacokinetics data described its absorption from the diet and its body excretion, the mechanisms involved in the uptake and transport of silicon across the gut wall have not been established. METHODS AND RESULTS: Caco-2 cells were used as a well-accepted in vitro model of the human intestinal epithelium to investigate the transport, across the intestinal barrier in both the absorption and excretion directions, of silicon supplied as orthosilicic acid stabilized by vanillin (OSA-VC)...

SCOPE: Inflammation-related diseases are a worldwide problem. The counteraction of inflammation with compounds activating the trigeminal nerve is one strategy to fight these diseases. Known trigeminally active compounds found in black or red pepper are the tingling t-pellitorine, the pungent capsaicin and the less pungent nonivamide. The presented study compares the anti-inflammatory potential of nonivamide to the two known anti-inflammatory compounds, elucidating the mechanism of action and the role of transient receptor protein channels...
