In this study, the bioaccessibility of phenolic compounds after in vitro gastrointestinal digestion of two cherry cultivars was assessed. The phenolic profile was modified during in vitro digestion, with a considerable decrease of total and individual phenolic compounds. Hydroxycinnamic acids and especially coumaroylquinic acids showed the highest bioaccessibility. Isomerisation of caffeoylquinic and coumaroylquinic acids was observed after in vitro digestion. Modification of the phenolic profile after digestion resulted in an increased or decreased scavenging activity depending on the assay...

Dietary interventions may effectively control cancer development, with phytosterols (PS) being a class of cancer chemopreventive dietary phytochemicals. The present study, for the first time, evaluates the antiproliferative effects of a PS-ingredient used for the enrichment of several foods and its main PS, β-sitosterol, at physiological serum levels, in the most prevalent cancer cells in women (breast (MCF-7), colon (HCT116) and cervical (HeLa)). In all three cell lines, these compounds induced significant cell viability reduction without a clear time- and dose-dependent response...

Low folate status is a risk factor for birth defects. We studied concentrations of red blood cell (RBC)- and serum folate in 198 German women in relation to information on dietary folate intake, demographic and lifestyle factors. Median serum- and RBC-folate levels were; (14.7 and 589 nmol/L, respectively. Serum < 7.0 nmol/L or RBC-folate < 405 nmol/L were observed in 3.5% and 18.7% of the women, respectively. Three per cent of the women had both lowered serum and RBC-folate. Whereas RBC-folate > 952 nmol/L (optimal levels around conception) were observed in 9...

Dietary nitrate may improve exercise tolerance in some healthy and clinical populations. Existing data regarding dietary nitrate in COPD is inconsistent. We conducted a 14d double-blind, randomised, placebo-controlled, crossover trial of daily nitrate-rich beetroot juice (BRJ; 12.9 mmol) versus nitrate-depleted BRJ (PL; 0.5 mmol). At baseline and after each condition, we assessed functional capacity (incremental shuttle walk test; ISWT), ambulatory blood pressure, pulmonary function, quality of life as well as exhaled nitric oxide (eNO), and plasma nitrate/nitrite (NOx)...

The main phenol in mate and coffee, 5-caffeoylquinic-acid (5-CQA), and its relevant microbial metabolites, dihydrocaffeic (DHCA) and dihydroferulic (DHFA) acids, have shown oxidative-stress protective effects in HepG2 cells. To evaluate possible endothelial-protective effects of the extracts and compounds, endothelial EA.hy926 cells were pre-treated with yerba mate (YME) and green coffee bean (GCBE) phenolic extracts, 5-CQA, DHCA and DHFA and afterwards stressed with tumour-necrosis-factor-alpha (TNF-α). Then oxidative-stress markers and endothelial-nitric-oxide-synthase levels were studied...

Iodine deficiency remains a worldwide problem with two billion individuals having insufficient iodine intake. Universal salt iodisation was declared by UNICEF and WHO as a safe, cost-effective, and sustainable way to tackle iodine deficiency. In Portugal, the few studies available unravel an iodine status below the WHO guidelines for pregnant women and school-aged children. In the present study, the iodine levels of household salt consumed in Portugal was assessed, for the first time. Non-iodised (median 14 ppm) and fortified (median 48 ppm) marine salt samples showed iodine levels lower than the minimum and above the maximum threshold recommended by non-mandatory Portuguese law and WHO recommendations, respectively...

This work aims to evaluate the structure-stability relationship of anthocyanins in cell culture. An early degradation time (C T10 ) and half-degradation time (C T50 ) were used to characterise the stability of 10 of the most common anthocyanins, incubated with DMEM at 37 °C, pH = 7.4, 5% CO2 for different time periods. According to the glycosylation, the glycosylated forms were more stable than the not glycosylated forms. The methylation at 3'' or 5' position at ring B enhanced their stability; contrarily, the hydroxylation at 3' or 5' position at ring B weakened their stability...

Sweet taste is associated with food reward and energy source in the form of carbohydrate. Excessive sweet consumption is blamed for the prevalence of obesity. However, evidence for the potential of sweet taste to influence food intake and bodyweight regulation in humans remains unclear. The purpose of this review was to examine the physiological responses relevant to sweet taste mechanisms and the impact on appetite control. The literature was examined for studies that assessed the effects of non-nutritive sweeteners and natural sugars on hormonal secretions and neural activations via oral and gastrointestinal pathways...

Physical and chemical parameters of rainbow trout fillets were tested during 120 days of frozen storage and following cooking. The fillets were obtained from rainbow trout-fed diets where dietary fishmeal was substituted with Hermetia illucens meal at 0, 25 and 50% inclusion levels, corresponding to control (C), Hi25, and Hi50 diets. Variations in quality traits of fillets emerged after 30 days of frozen storage, however they remained almost unchanged for the other 90 days. Increasing levels of H. illucens did not affect pH, shear stress, colour and water holding capacity of fillets...

Previous studies have shown that osteopontin (OPN) can enhance infant resistance to infection. However, the underlying mechanisms remain to be explored. Here, we studied the effects of OPN on the development and functions of immune cells in infant rats fed with OPN-enriched formula (OF) compared with regular formula (RF). After 21 days feeding, the proportion of infant rats' CD3+ T cells of lymph nodes in the OF group is significantly increased compared with the RF group. The proportion of CD4+ and CD8+ T cells of lymph nodes in the OF group is closer to the breast feeding (BF) group than to the RF group...

Increased superoxide production by phagocytic NADPH oxidase has been associated with inflammatory conditions. Growing evidences suggest that dietary polyphenols may modulate the expression of NADPH oxidase subunits. Herein, we examined whether soluble mate tea (SMT) consumption - a polyphenol-rich beverage - affects the expression of the leukocyte NADPH oxidase protein p47phox and/or circulating biomarkers of inflammation and antioxidant biomarkers in humans. In a two-phase study, nine men were requested to drink water (control) for 8 d and then follow a second 8-d period drinking SMT...
