Scope Plant secondary metabolites, such as phenolic acids are commonly associated with benefits for human health. Two of the most abundant phenylpropanoid‐derived compounds detected in faecal samples phenylacetic acid (PAA) and 4‐hydroxylphenylacetic (4‐hydroxyPAA). Although they have potential to be derived from diets rich plant‐based foods, evidence suggests that these can microbial fermentation aromatic amino (AAAs) colon. Methods results To identify bacteria responsible, 26 strains...
Sustainable sources of high-protein plants could help meet future protein requirements. Buckwheat, green pea, fava bean, hemp, and lupin were analyzed by proximate analysis inductively coupled plasma mass spectrometry to determine their macro- micronutrient contents, liquid chromatography-mass was used elucidate the phytochemical profiles. The contents ranged from 20 43% (w/w), all samples found be rich in insoluble fiber: 9-25% (w/w). selected crops had a favorable profile, with phosphorus...
Abstract Scope : Natural dietary anti‐obesogenic phytochemicals may help combat the rising global incidence of obesity. We aimed to identify key hepatic pathways targeted by anti‐obsogenic ginger fed mice. Methods and results Weaning mice were a high‐fat diet containing 6‐gingerol (HFG), zerumbone (HFZ), characterized rhizome extract ginger‐related plant Alpinia officinarum Hance (high fat goryankang, HFGK) or no (high‐fat control, HFC) for 6 wks compared with on low‐fat control (LFC)....
Background Ruminococcus flavefaciens is an important fibre-degrading bacterium found in the mammalian gut. Cellulolytic strains from bovine rumen have been shown to produce complex cellulosome structures that are associated with cell surface. R. 007 a highly cellulolytic strain whose ability degrade dewaxed cotton, but not Avicel cellulose, was lost following initial isolation variant 007S. The recovered after serial subculture give cotton-degrading 007C. This has allowed us investigate...
Scope Olive products are rich in phenolic compounds, which natural antioxidants vitro. We tested the vivo effects of alperujo, an olive production by‐product, as well hydroxytyrosol and 3,4‐dihydroxyphenylglycol ( DHPG ) isolated from on indices pathways oxidative metabolic stress a vitamin E ‐deficient rat model. Methods results Rats were fed diet for 10 weeks, followed by this supplemented with either 100 mg/kg dα‐tocopherol, alperujo extract, hydroxytyrosol, or , further 2 weeks. detected...
Scope Phytophenols present in cereals are metabolised to compounds that could be partly responsible for the reduced risk of chronic diseases and all‐cause mortality associated with fibre‐rich diets. The bioavailability, form vivo concentrations these metabolites require established. Materials methods Eight healthy volunteers consumed a test meal containing recommended dose (40 g) high (120 ready‐to‐eat wheat bran cereal systemic colonic determined quantitatively by LC‐MS. Conclusion Analysis...
This study evaluated the postprandial effects following consumption of buckwheat, fava bean, pea, hemp and lupin compared to meat (beef); focussing on biomarkers satiety, gut hormones, aminoacids plant metabolites bioavailability metabolism.Ten subjects (n = 3 men; n 7 women; 42 ± 11.8 years age; BMI 26 5.8 kg/m2) participated in six 1-day independent acute interventions, each meal containing 30 g protein from hemp, (beef). Blood samples were collected during 24-h VAS questionnaires over...
Mycotoxins are potent fungal toxins that frequently contaminate agricultural crops and foods. Mycotoxin exposure is reported in humans, children known to be particularly at risk of exceeding safe levels exposure. Urinary biomonitoring used assess overall dietary multiple mycotoxins. This study aims quantify multi-mycotoxin UK identify major food groups contributing Four repeat urine samples were collected from 29 (13 boys 16 girls, aged 2.4–6.8 years), diaries recorded their eleven Urine (n...
Benefits from micronutrients within fruit juice and smoothies are well documented, but fewer studies research the role of phytochemicals. Well-controlled human essential to evaluate their impact, particularly on glucose lipid regulation also gastrointestinal health. Planning these requires data potential molecular targets. Here we report a comprehensive metabolomic (LC-MS) analysis phytochemical composition four commonly consumed beverages, including whether they free be absorbed early in...
The proteomes and glucosinolate content of two commercial rapeseed meals produced by cold-pressing pre-press solvent extraction were investigated with the aim identifying process-related differences between them. One-dimensional protein electrophoresis their corresponding isolates revealed similarities in band distribution cold-pressed extracted samples. Two-dimensional coupled mass spectrometry confirmed that seed storage cruciferin was major both either intact or form α- β-polypeptide...
Only 6 to 8 % of the UK adults meet daily recommendation for dietary fibre. Fava bean processing lead vast amounts high-fibre by-products such as hulls. Bean hull fortified bread was formulated increase and diversify fibre while reducing waste. This study assessed hull: suitability a source fibre; systemic microbial metabolism its components postprandial events following rolls. Nine healthy participants (53·9 ± 16·7 years) were recruited randomised controlled crossover attending two 3 days...
