The objective of this study was to evaluate the effects of a supplementation of pomegranate seed oil (PSO), being rich in punicic acid, on the biochemical parameters of healthy rats. PSO was given to the animals intragastrically for 40 days at concentrations of 1%, 2% and 4%. There were no changes in their total body weight gain, their serum biochemical markers, or in the oxidative stress in their tissues. However, the TBARS values were reduced in the brains of the animals, noting that no significant amounts of conjugated fatty acids were found in this tissue...

For over 4000 years, liquorice has been one of the most frequently employed botanicals as a traditional herbal medicine. Although previous reports have found that liquorice flavonoids possess various health beneficial effects, the underlying mechanism responsible for the anti-diabetic effect of liquorice flavonoids remains unclear. The present study demonstrates that liquorice flavonoid oil (LFO) improves type 2 diabetes mellitus through GLUT4 translocation to the plasma membrane by activating both the adenosine monophosphate-activated protein kinase (AMPK) pathway and Akt pathway in muscle of KK-Ay mice...

In this work we investigated, in populations located in Central Asia, the relationship between PROP taste perception and vegetables liking and consumption using FAOSTAT dataset. Collected data were analysed using distance matrices, Mantel test and Pearson correlation. Populations showing similar ability in tasting PROP bitterness are more similar as respect to vegetable consumption (r = 0.63, p-value = .05). Moreover, a significant negative correlation was found between the percentage of Non Taster (NT) in different countries and the percentage of vegetable consumption (r = -0...

A total of 1776 Chinese adults, aged 40-60 years, had been recruited to participate in the Hefei Nutrition and Health Study started in 2012. Three major dietary patterns were identified, "High-salt and high-fat", "Traditional Chinese" and "Western" dietary patterns. After adjusting for potential confounders, there is no significant difference in the effect of different dietary pattern quintiles on the risk of type 2 diabetes (T2D). However, compared with lowest quintile intakes, the adjusted odds ratio of T2D for highest quintile intakes of bread and noodle, rice noodle and coarse grain were 2...

We have previously reported an aqueous extract of fermented barley with Lactobacillus plantarum dy-1 (LFBE) has more efficient anti-obesity effect compared with that of Saccharomyces cerevisiae. To further explore associated effects of LFBE on body weight and body fat distribution, and lipid profiles related metabolic outcomes, serum metabolites were analysed using LC-MS-MS and partial least-squares-discriminant analysis (PLS-DA). Obese and lean groups were clearly discriminated from each other on PLS-DA score plot and major metabolites contributing to the discrimination were assigned as lipid metabolites (fatty acids), lipid metabolism intermediates (choline, betaine, carnitine and butyryl-carnitine), amino acids and citric acid...

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...

Intake of red and processed meat increases the risk of colorectal cancer (CRC), whereas dairy product consumption and the intake of dietary fibre are negatively associated with this risk. We investigated the effect of (i) low-protein diets with either whey or cooked meat (beef) as the protein source and (ii) high-protein diets with cooked meat (beef) either without or with the inclusion of 10% butyrylated high-amylose maize starch (HAMSB), on the urinary metabolome of rats. Urine samples from rats were analysed using untargeted LC-MS metabolomics...

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...

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...

This narrative review summarises the main studies of the role of the different fatty acids in coronary heart disease (CHD) and cardiovascular disease (CVD) risk and the current scientific debate on dietary recommendations. Reduction and substitution of the saturated fatty acids (SFAs) with the polyunsaturated fatty acids (PUFAs) are still the main dietary recommendation to prevent CHD and CVD. In the last few years, however, the strength of the scientific evidence underlying this dietary advice has been questioned...

Dietary polyphenols, including flavonoids, are abundantly present in a healthy and balanced diet. Evidence for their role in preventing non-communicable diseases is emerging. We examined the association between estimated habitual intake of dietary flavonoid and obesity in a cohort study. After adjusting for potential confounding factors, inverse association between total flavonoid intake and excess weight (BMI ≥25) was found (OR = 0.66, 95% CI: 0.45, 0.99); among individual classes of flavonoids, only flavanones were inversely associated with excess body weight (OR = 0...
