  • Polyphenol intake and metabolic syndrome risk in European adolescents: the
           HELENA study
    • Abstract: Purpose The role of polyphenol intake during adolescence to prevent metabolic syndrome (MetS) is little explored. This study aimed to evaluate the association between intake of total polyphenols, polyphenol classes and the 10 most consumed individual polyphenols with MetS risk in European adolescents. Methods Of the cross-sectional HELENA study, 657 adolescents (54% girls; 14.8% overweight; 12.5–17.5 year) had a fasting blood sample and polyphenol intake data from two non-consecutive 24-h recalls matched with the Phenol-Explorer database. MetS was defined via the pediatric American Heart Association definition. Multilevel linear regressions examined the associations of polyphenol quartiles with MetS components, while logistic regression examined the associations with MetS risk. Results After adjusting for all potential confounders (socio-demographics and nine nutrients), total polyphenol intake, polyphenol classes and individual polyphenols were not associated with MetS risk. From all MetS components, only BMI z-score was modestly inversely associated with total polyphenol intake. Further sub analyses on polyphenol classes revealed that flavonoid intake was significantly associated with higher diastolic blood pressure and lower BMI, and phenolic acid intake was associated with higher low-density cholesterol. For individual polyphenols, the above BMI findings were often confirmed (not independent from dietary intake) and a few associations were found with insulin resistance. Conclusion Higher intakes of total polyphenols and flavonoids were inversely associated with BMI. No consistent associations were found for other MetS components.

  • Inflammatory potential of diet and risk of lymphoma in the European
           Prospective Investigation into Cancer and Nutrition
    • Abstract: Introduction Chronic inflammation plays a critical role in lymphomagenesis and several dietary factors seem to be involved its regulation. The aim of the current study was to assess the association between the inflammatory potential of the diet and the risk of lymphoma and its subtypes in the European Investigation into Cancer and Nutrition (EPIC) study. Methods The analysis included 476,160 subjects with an average follow-up of 13.9 years, during which 3,136 lymphomas (135 Hodgkin lymphoma (HL), 2606 non-Hodgkin lymphoma (NHL) and 395 NOS) were identified. The dietary inflammatory potential was assessed by means of an inflammatory score of the diet (ISD), calculated using 28 dietary components and their corresponding inflammatory weights. The association between the ISD and lymphoma risk was estimated by hazard ratios (HR) and 95% confidence intervals (CI) calculated by multivariable Cox regression models adjusted for potential confounders. Results The ISD was not associated with overall lymphoma risk. Among lymphoma subtypes, a positive association between the ISD and mature B-cell NHL (HR for a 1-SD increase: 1.07 (95% CI 1.01; 1.14), p trend = 0.03) was observed. No statistically significant association was found among other subtypes. However, albeit with smaller number of cases, a suggestive association was observed for HL (HR for a 1-SD increase = 1.22 (95% CI 0.94; 1.57), p trend 0.13). Conclusions Our findings suggested that a high ISD score, reflecting a pro-inflammatory diet, was modestly positively associated with the risk of B-cell lymphoma subtypes. Further large prospective studies on low-grade inflammation induced by diet are warranted to confirm these findings.

  • Moderate consumption of fermented alcoholic beverages diminishes
           diet-induced non-alcoholic fatty liver disease through mechanisms
           involving hepatic adiponectin signaling in mice
    • Abstract: Purpose Results of some epidemiological studies suggest that moderate alcohol consumption may be associated with a decreased risk to develop NAFLD. Here, the effect of the consumption of moderate beer and diluted ethanol, respectively, on the development of NAFLD were assessed. Methods Female C57BL/6J mice were fed a control diet (C-D) or a diet rich in fructose, fat and cholesterol (FFC) enriched isocalorically and isoalcoholically with beer (FFC + B) or plain ethanol (FFC + E) (2.5 g ethanol/kg body weight/day) for 7 weeks. Liver damage was assessed by histology using NAFLD activity score. Markers of inflammation, insulin resistance and adiponectin signaling were measured at mRNA and protein levels. Using J774A.1 cells as a model of Kupffer cells, the effect of alcoholic beverages on adiponectin receptor 1 (Adipor1) was assessed. Results Hepatic triglyceride concentration, neutrophil granulocytes, iNOS protein concentrations and early signs of insulin resistance found in FFC-fed mice were significantly attenuated in FFC+ B-fed mice (P < 0.05 for all). These findings were associated with a super-induction of Adipor1 mRNA expression (+ ~ 18-fold compared to all other groups) and a decrease of markers of lipid peroxidation in liver tissue of FFC + B-fed mice when compared to FFC-fed animals. Similar differences were not found between FFC– and FFC+ E-fed mice. Expression of Adipor1 was also super-induced (7.5-fold) in J774A.1 cells treated with beer (equivalent to 2 mmol/L ethanol). Conclusions These data suggest that moderate intake of fermented alcoholic beverages such as beer at least partially attenuates NAFLD development through mechanisms associated with hepatic AdipoR1 expression.

  • B etaine - rich sugar beet molasses protects from homocysteine-induced
           reduction of survival in Caenorhabditis elegans
    • Abstract: Purpose Homocysteine (Hcy) in humans represents a blood-borne biomarker which predicts the risk of age-related diseases and mortality. Using the nematode Caenorhabditis elegans, we tested whether feeding betaine-rich sugar beet molasses affects the survival under heat stress in the presence of Hcy, in spite of a gene loss in betaine–homocysteine methyltransferase. Methods Knockdown of the genes relevant for remethylation or transsulfuration of Hcy was achieved by RNA interference (RNAi). Survival assay was conducted under heat stress at 37 °C and Hcy levels were determined by enzyme-linked immunosorbent assay. Results Addition of 500 mg/l betaine-rich sugar beet molasses (SBM) prevented the survival reduction that was caused by exposure to Hcy at 37 °C. Although SBM was no longer capable of reducing Hcy levels under RNAi versus homologues for 5, 10-methylenetetrahydrofolate reductase or cystathionine-β-synthase, it still enabled the survival extension by SBM under exposure to Hcy. In contrast, RNAi for the small heat shock protein hsp-16.2 or the foxo transcription factor daf-16 both prevented the extension of survival by betaine-rich molasses in the presence of Hcy. Conclusions Our studies demonstrate that betaine-rich SBM is able to prevent survival reduction caused by Hcy in C. elegans in dependence on hsp-16.2 and daf-16 but independent of the remethylation pathway.

  • Consumption of a soy drink has no effect on cognitive function but may
           
    • Abstract: Purpose Cognitive decline is commonly reported during the menopausal transition, with memory and attention being particularly affected. The aim of this study was to investigate the effects of a commercially available soy drink on cognitive function and menopausal symptoms in post-menopausal women. Methods 101 post-menopausal women, aged 44–63 years, were randomly assigned to consume a volume of soy drink providing a low (10 mg/day; control group), medium (35 mg/day), or high (60 mg/day) dose of isoflavones for 12 weeks. Cognitive function (spatial working memory, spatial span, pattern recognition memory, 5-choice reaction time, and match to sample visual search) was assessed using CANTAB pre- and post-the 12 week intervention. Menopausal symptoms were assessed using Greene’s Climacteric Scale. Results No significant differences were observed between the groups for any of the cognitive function outcomes measured. Soy drink consumption had no effect on menopausal symptoms overall; however, when women were stratified according to the severity of vasomotor symptoms (VMS) at baseline, women with more severe symptoms at baseline in the medium group had a significant reduction (P = 0.001) in VMS post-intervention (mean change from baseline score: − 2.15 ± 1.73) in comparison to those with less severe VMS (mean change from baseline score: 0.06 ± 1.21). Conclusions Soy drink consumption had no effect on cognitive function in post-menopausal women. Consumption of ~ 350 ml/day (35 mg IFs) for 12 weeks significantly reduced VMS in those with more severe symptoms at baseline. This finding is clinically relevant as soy drinks may provide an alternative, natural, treatment for alleviating VMS, highly prevalent among western women.

  • Beneficial effects of ginger on prevention of obesity through modulation
           of gut microbiota in mice
    • Abstract: Purpose Recent evidence has demonstrated that the gut microbiota plays a critical role in the treatment of obesity and other metabolic dysfunctions. Ginger (Zingiber officinale Roscoe), one of the most commonly used spices and dietary supplements, has been shown to exert beneficial effects against obesity and related disorders. However, to date, the mechanisms linking these effects to the gut microbiota remain unclear. This study aims to investigate the relationship between the gut microbiota and the metabolic adaptations resulting from ginger supplementation in mice. Methods Four groups of mice were fed a normal chow diet (NCD) or a high-fat diet (HFD) with or without ginger supplementation for 16 weeks. Lipid profiles, proinflammatory cytokines, glucose tolerance, microbiota composition and short-chain fatty acid (SCFA) concentrations were analyzed at the end of the experiment. In addition, microbiota-depleted mice were transplanted with the fecal microbiota of mice fed a HFD or mice fed a HFD along with ginger supplementation. Glucose tolerance and microbiota composition were assessed after a 8-week fecal microbiota transplantation (FMT). Results We observed marked decreases in body weight, liver steatosis, and low-grade inflammation as well as amelioration of insulin resistance in the HFD-fed mice treated with ginger. Furthermore, ginger supplementation modulated the gut microbiota composition and increased species belonging to the Bifidobacterium genus and SCFA-producing bacteria (Alloprevotella and Allobaculum), along with increases in fecal SCFA concentrations. The FMT experiment showed anti-obesity and microbiota-modulating effects similar to those observed in the oral ginger-feeding experiment. Conclusions This study suggests that modulation of the gut microbiota as a result of ginger supplementation has a therapeutic effect on obesity in mice.

  • Patterns and sociodemographic determinants of water intake by children in
           China: results from the first national population-based survey
    • Abstract: Purpose Accurate data on water and beverage intakes are essential for assessing hydration adequacy and setting proper guidelines. The objective of this study is to identify the patterns and sociodemographic determinants of water intake and to assess the intake adequacy for children in China. Methods The study team recruited 41,439 children aged 6–17 years using a multi-stage cluster random sampling method. Daily water and beverage intakes were investigated with the standard questionnaires and measuring containers in face-to-face interviews. Each participant was assigned an adjustment weight to obtain a nationally representative sample. Sociodemographic factors influencing water intake were identified using multi-variable regressions. Water intake adequacy was evaluated by comparing with the recommended water intake (RWI). Results The mean ± standard deviation of total water intake (TWI) was 1603 ± 731 mL/day for boys and 1487 ± 661 mL/day for girls. Plain water, food moisture, and other beverages contributed 51%, 20%, and 29% of the TWI. Multi-variable analyses showed that TWI of children increased with age, in urban areas and day schools, and with parents’ economic and educational levels. The majority (82%) of children had TWI not meeting the corresponding RWI, and the percentage increased with age except for 14–17-year-old boys. Conclusions Plain water is still the major source of daily water intake by children in China. Unfortunately, the majority of children do not have sufficient water intake, which warrants future actions and guidelines targeting adequate hydration.

  • Combined choline and DHA supplementation: a randomized controlled trial
    • Abstract: Objective Choline and docosahexaenoic acid (DHA) are essential nutrients for preterm infant development. They are metabolically linked via phosphatidylcholine (PC), a constitutive plasma membrane lipid and the major transport form of DHA in plasma. Plasma choline and DHA-PC concentrations rapidly decline after preterm birth. To improve preterm infant nutrition, we evaluated combined compared to exclusive choline and DHA supplementation, and standard feeding. Design Randomized partially blinded single-center trial. Setting Neonatal tertiary referral center in Tübingen, Germany. Patients 24 inborn preterm infants < 32 week postmenstrual age. Interventions Standard nutrition (control) or, additionally, enteral choline (30 mg/kg/day), DHA (60 mg/kg/day), or both for 10 days. Single enteral administration of 3.6 mg/kg [methyl-D9-] choline chloride as a tracer at 7.5 days. Main outcome measures Primary outcome variable was plasma choline following 7 days of supplementation. Deuterated and unlabeled choline metabolites, DHA-PC, and other PC species were secondary outcome variables. Results Choline supplementation increased plasma choline to near-fetal concentrations [35.4 (32.8–41.7) µmol/L vs. 17.8 (16.1–22.4) µmol/L, p < 0.01] and decreased D9-choline enrichment of PC. Single DHA treatment decreased DHA in PC relative to total lipid [66 (60–68)% vs. 78 (74–80)%; p < 0.01], which was prevented by choline. DHA alone increased DHA-PC only by 35 (26–45)%, but combined treatment by 63 (49–74)% (p < 0.001). D9-choline enrichment showed preferential synthesis of PC containing linoleic acid. PC synthesis via phosphatidylethanolamine methylation resulted in preferential synthesis of DHA-containing D3-PC, which was increased by choline supplementation. Conclusions 30 mg/kg/day additional choline supplementation increases plasma choline to near-fetal concentrations, dilutes the D9-choline tracer via increased precursor concentrations and improves DHA homeostasis in preterm infants.

  • The effect of probiotics on inflammatory biomarkers: a meta-analysis of
           randomized clinical trials
    • Abstract: Purpose No study has summarized earlier findings on the effect of probiotic supplementation on inflammatory biomarkers. This systematic review and meta-analysis was conducted to systematically review the available placebo-controlled clinical trials about the effect of probiotic supplementation on several inflammatory biomarkers in adults. Methods Relevant papers published up to March 2018 were searched up through PubMed, MEDLINE, SCOPUS, EMBASE, and Google Scholar, using following suitable keywords. Clinical trials that examined the effect of probiotic supplementation on inflammation in adults were included. Results Overall, 42 randomized clinical trials (1138 participants in intervention and 1120 participants in control groups) were included. Combining findings from included studies, we found a significant reduction in serum hs-CRP [standardized mean difference (SMD) − 0.46; 95% CI − 0.73, − 0.19], TNF-a (− 0.21; − 0.34, − 0.08), IL-6 (− 0.37; − 0.51, − 0.24), IL-12 (− 0.47; − 0.67, − 0.27), and IL-4 concentrations (− 0.48; − 0.76, − 0.20) after probiotic supplementation. Pooling effect sizes from 11 studies with 12 effect sizes, a significant increase in IL-10 concentrations was seen (0.21; 0.04, 0.38). We failed to find a significant effect of probiotic supplementation on serum IL-1B (− 0.17; − 0.37, 0.02), IL-8 (− 0.01; − 0.30, 0.28), and IFN-g (− 0.08; − 0.31, 0.15) and IL-17 concentrations (0.06; − 0.34, 0.46). Conclusions Probiotic supplementation significantly reduced serum concentrations of pro-inflammatory cytokines including, hs-CRP, TNF-a, IL-6, IL-12, and IL-4, but it did not influence IL-1B, IL-8, IFN-g, and IL-17 concentrations. A significant increase in serum concentrations of IL-10, as a anti-inflammatory cytokine was also documented after probiotic supplementation.

  • Vitamin D-fortified foods improve wintertime vitamin D status in women of
           Danish and Pakistani origin living in Denmark: a randomized controlled
           trial
    • Abstract: Purpose Low vitamin D status is prevalent worldwide. We aim to investigate the effect of vitamin D fortification on serum 25-hydroxyvitamin D (25(OH)D) concentration in women of Danish and Pakistani origin at risk of vitamin D deficiency. Methods A 12-week randomized, double-blinded, placebo-controlled intervention trial during winter time, designed to provide 20 µg vitamin D3/day through fortified yoghurt, cheese, eggs and crisp bread, and assess the change in serum 25(OH)D. Participants were 143 women of Danish and Pakistani origin, living in Denmark, randomized into four groups, stratified by ethnicity. Results Mean (SD) baseline 25(OH)D concentrations among women of Danish and Pakistani origin were 49.6 (18) and 46.9 (22) nmol/L, respectively (P = 0.4). While 9% of Danish women had 25(OH)D < 30 nmol/L, the prevalence among women of Pakistani origin was 24%. Median (IQR) vitamin D intake among Danish and Pakistani women at endpoint was 32.0 (27.0, 34.4) µg/day and 24.2 (19.2, 30.8) µg/day, respectively. Endpoint serum 25(OH)D increased in fortified groups to 77.8 (14) nmol/L among Danish women and 54.7 (18) nmol/L among women of Pakistani origin (P < 0.01). At endpoint, 0% in the Danish-fortified group and 3% in the Pakistani-fortified group had 25(OH)D < 30 nmol/L, compared with 23 % and 34% in their respective control groups. Conclusions Vitamin D fortification of four different foods for 12 weeks during winter was effective in increasing serum 25(OH)D and reducing the prevalence of very low vitamin D status among women of Danish and Pakistani origin.

  • Food intake of folate, folic acid and other B vitamins with lung cancer
           risk in a low-income population in the Southeastern United States
    • Abstract: Purpose We prospectively examined associations of lung cancer risk with food intake of B vitamins involved in one-carbon metabolism and the use of folic acid-containing supplements among a low-income population of black and white adults in the Southeastern US. Methods Within the Southern Community Cohort Study, we included 1064 incident lung cancer cases among 68,236 participants aged 40–79 years at study enrollment. Food intake and the use of folic acid-containing supplements were assessed using a validated food frequency questionnaire at study enrollment. Multivariate Cox regression was used to estimate hazards ratios (HRs) and the 95% confidence intervals (CIs). Results Folate and/or folic acid intake from food were not associated with lung cancer risk; HRs (95% CI) for highest compared with lowest quartile were 1.08 (0.91–1.29) for total dietary folate, 1.00 (0.84–1.19) for food folate, and 1.09 (0.91–1.30) for food folic acid, respectively. Similarly, no associations were observed after stratifying by sex, race and smoking status, except for a positive association with total dietary folate intake among black women (HR 1.46, 95% CI 1.04–2.05 for the highest quartile compared with the lowest quartile, P trend = 0.02). Neither the use of folic acid-containing supplements nor food intake of vitamin B6, vitamin B12 and riboflavin were associated with lung cancer risk. Conclusions Our findings do not support a protective effect of folate or folic acid for lung cancer prevention in a low-income population of black and white adults in the Southeastern US. Our finding of a positive association with total dietary folate intake among black women needs to be interpreted with caution and replicated in other studies.

  • The novel insight into anti-inflammatory and anxiolytic effects of
           psychobiotics in diabetic rats: possible link between gut microbiota and
           brain regions
    • Abstract: Purpose Type 2 diabetes mellitus (T2DM) was associated with gut microbial impairment (dysbiosis) and neurological and behavioral disorders. The role of the gut–brain axis in the management of many diseases including T2DM has been the focus of much research activity in the recent years. However, a wide knowledge gap exists about the gut microbial effects on the function of glia cells. Hence, the present study was aimed to examine the effects of psychobatics on dysbiosis and glia cells function in enteric and central nervous system with an inflammatory insight in T2DM. Methods Thirty rats were treated by Lactobacillus (L.) plantarum, inulin, or their combination (synbiotic) for 8 weeks after inducing T2DM. Fecal sample was collected to evaluate gut microbial composition. Then, the rats were sacrificed, and the colon, amygdala, and prefrontal cortex (PFC) were studied. Results T2DM resulted in dysbiosis and increased levels of glial cell-derived neurotrophic factor (GDNF), glial fibrillary acidic protein (GFAP), and inflammatory markers (IL-17, IL-6, and TLR-2) in the colon and brain. However, concurrent supplementation of L. plantarum and inulin could improve the gut microbial composition as well as reduce the levels of inflammatory cytokines. While the administration of L. plantarum led to a significant decrease in TLR-2 as well as GDNF and GFAP only in the amygdala, the synbiotic intake could make such changes in the colon, amygdala, and PFC. Conclusions Our findings demonstrated an innovative approach to the beneficial effects of psychobiotics in neuroinflammation and behavioral performance through gut microbiota changes, focusing on possible role of glial cells in gut–brain axis.

  • Association of free sugar intake with blood pressure and obesity measures
           in Australian adults
    • Abstract: Purpose This study examined the association of free sugar (FS) intake with obesity measures and blood pressure (BP) among a nationally representative sample of Australian adults. Methods Data from adults (weighted n = 5136) who completed 2 × 24-h recalls and had complete data for BP, waist circumference (WC), waist-to-height ratio (WHtR), and body mass index (BMI) were analyzed. Associations between percentage energy of FS from all food sources (%EFStotal), beverages only (%EFSbeverages), and non-beverages sources only (%EFSnon-beverages) and obesity measures and BP were examined using linear and non-linear regressions. Logistic regression was used to calculate the odds ratios (OR) of being classified as overweight and/or obese, having increased cardiometabolic risks, and elevated BP per 5% point increase in %EFStotal, %EFSbeverages, and %EFSnon-beverages. All regression analyses were adjusted for known socio-economic and lifestyle confounders. Results %EFSbeverage was positively associated with BMI, WC, and WHtR (all p < 0.05), while %EFSnon-beverage was inversely associated with these outcomes. Increases in odds of having an undesirable WC/WHtR were found with increasing %EFSbeverages (OR per 5% point increase in %EFSbeverages: 1.19 for WC; 1.23 for WHtR, both p < 0.001). %EFStotal and %EFSnon-beverages were weakly and negatively associated with diastolic BP. A 5% point increase in %EFStotal and %EFSnon-beverage was associated with a 10–25% reduction in odds of having elevated BP. Conclusions Our results suggested that only a higher FS intake from beverages may be associated with obesity, and higher FS intake was associated with reduced odds of having elevated BP.

  • Effectiveness of increased salt iodine concentration on iodine status:
           trend analysis of cross-sectional national studies in Switzerland
    • Abstract: Purpose Despite longstanding voluntary salt iodisation in Switzerland, data suggest inadequate iodine intake in vulnerable population groups. In response, the salt iodine concentration was increased from 20 to 25 mg/kg and we assessed the impact on iodine status. Methods We conducted a cross-sectional national study in school-age children (n = 731), women of reproductive age (n = 353) and pregnant women (n = 363). We measured urinary iodine concentration (UIC) and urinary sodium concentration (UNaC) in spot urine samples. The current median UIC was compared with national data from 1999, 2004 and 2009. We measured TSH, total T4 and thyroglobulin (Tg) on dried blood spot samples collected in women. Results The median UIC (bootstrapped 95% CI) was 137 µg/L (131, 143 µg/L) in school children, 88 µg/L (72, 103 µg/L) in women of reproductive age and 140 µg/L (124, 159 µg/L) in pregnant women. Compared to 2009, the median UIC increased modestly in school children (P < 0.001), but did not significantly change in pregnant women (P = 0.417). Estimated sodium intake exceeded the recommendations in all population groups. The prevalence of thyroid disorders in women was low, but Tg was elevated in 13% of the pregnant women. Conclusion Iodine intake is overall adequate in Swiss school-age children, but only borderline sufficient in pregnant and non-pregnant women, despite high salt intakes and satisfactory household coverage with iodized salt. Our findings suggest increasing the concentration of iodine in salt may not improve iodine intakes in women if iodised salt is not widely used in processed foods. Registration This trial was registered at clinicaltrials.gov as NCT02312466.

  • Fluid balance and hydration status in combat sport Olympic athletes: a
           systematic review with meta-analysis of controlled and uncontrolled
           studies
    • Abstract: Purpose Athletes in Olympic combat sports experience body water fluctuations resulting from training and intentional dehydration when making weight. Despite the popularity of urine specific gravity (USG) and urine osmolality (UOSM) measurement in characterizing fluid fluctuations, their utility remains questioned. This systematic review/meta-analysis examined the utility of urinary hydration indices in laboratory and field settings in Olympic combat sport athletes. Methods 27 articles met the inclusion criteria for systematic review, 15 studies were included in the meta-analysis; with USG and UOSM the main outcome variables. Meta-regression analyses evaluated the interrelationship among body mass (BM), fluid intake, and urine measures. Results Significant USG alterations were observed following different sampling time frames: dehydration (ES 0.59; 95% CI 0.46–0.72; p = 0.001), follow-up period (ES 0.31; 95% CI 0.11–0.50; p = 0.002) and rehydration (ES − 0.34; 95% CI − 0.56 to − 0.12; p = 0.003). Direct comparison of laboratory (ES 0.20; 95% CI − 0.19 to 0.59; p = 0.324) and field (ES 0.35; 95% CI 0.14–0.56; p = 0.001) sampling showed marginally trivial and small effects. Small effects on UOSM were observed following dehydration (ES 0.31; 95% CI 0.12–0.74, p = 0.15), follow-up period (ES 0.39; 95% CI 0.08–0.70, p = 0.015) and rehydration (ES − 0.45; 95% CI − 0.60 to 0.30, p = 0.001). Meta-regression analysis suggests only fluid intake predicts USG alterations (p = 0.044) during rehydration protocols. Conclusions There were likely small changes in both USG and UOSM readings across all experimental conditions, with moderate-to-large heterogeneity in all studies, except for USG readings during dehydration protocols. The meta-regression failed to provide conclusive evidence concerning the interrelationship among urine measures, BM fluctuations, and fluid intake.

  • Identification of potential human urinary biomarkers for tomato juice
           intake by mass spectrometry-based metabolomics
    • Abstract: Purpose Dietary biomarkers allow the accurate and objective determination of the dietary intake of humans and can thus be valuable for investigating the relation between consumption of foods and biochemical as well as physiological responses. The objective of this study was the identification of potential urinary biomarkers for consumption of tomato juice. Methods In the course of a dietary intervention study, the human urine metabolome of a study cohort was compared between a tomato-free diet and after intake of tomato juice by application of an LC-HRMS-based metabolomics approach. The data acquisition was achieved using an orbitrap mass spectrometer, followed by multistage data processing and univariate as well as multivariate statistical analysis to identify discriminating features. Results Statistical analysis revealed several unique features detectable after tomato juice intake. The most discriminating markers were putatively identified as hydroxylated and sulfonated metabolites of esculeogenin B, aglycone of the steroidal glycoalkaloid esculeoside B recently found in tomato juice. Furthermore, the β-carboline alkaloids tangutorid E and F and glucuronidated derivatives thereof were identified in urine. Conclusions Steroidal glycoalkaloids in tomato juice are cleaved after ingestion, and hydroxylated and sulfonated metabolites of their aglycones might serve as urinary biomarkers for tomato juice intake. Similarly, β-carboline alkaloids and glucuronidated derivatives were identified as potential urinary biomarkers. Both the aglycones of the steroidal alkaloids and the β-carboline alkaloids might exhibit biological activities worth investigating.

  • Creatine supplementation in Walker-256 tumor-bearing rats prevents
           skeletal muscle atrophy by attenuating systemic inflammation and protein
           degradation signaling
    • Abstract: Purpose The aim of this study was to investigate the effects of creatine supplementation on muscle wasting in Walker-256 tumor-bearing rats. Methods Wistar rats were randomly assigned into three groups (n = 10/group): control (C), tumor bearing (T), and tumor bearing supplemented with creatine (TCr). Creatine was provided in drinking water for a total of 21 days. After 11 days of supplementation, tumor cells were implanted subcutaneously into T and TCr groups. The animals’ weight, food and water intake were evaluated along the experimental protocol. After 10 days of tumor implantation (21 total), animals were euthanized for inflammatory state and skeletal muscle cross-sectional area measurements. Skeletal muscle components of ubiquitin–proteasome pathways were also evaluated using real-time PCR and immunoblotting. Results The results showed that creatine supplementation protected tumor-bearing rats against body weight loss and skeletal muscle atrophy. Creatine intake promoted lower levels of plasma TNF-α and IL-6 and smaller spleen morphology changes such as reduced size of white pulp and lymphoid follicle compared to tumor-bearing rats. In addition, creatine prevented increased levels of skeletal muscle Atrogin-1 and MuRF-1, key regulators of muscle atrophy. Conclusion Creatine supplementation prevents skeletal muscle atrophy by attenuating tumor-induced pro-inflammatory environment, a condition that minimizes Atrogin-1 and MuRF-1-dependent proteolysis.

  • Nutrients or nursing' Understanding how breast milk feeding affects
           child cognition
    • Abstract: Purpose To explore the associations between type of milk feeding (the “nutrients”) and mode of breast milk feeding (the “nursing”) with child cognition. Methods Healthy children from the GUSTO (Growing Up in Singapore Toward healthy Outcomes) cohort participated in repeated neurodevelopmental assessments between 6 and 54 months. For “nutrients”, we compared children exclusively bottle-fed according to type of milk received: formula only (n = 296) vs some/all breast milk (n = 73). For “nursing”, we included only children who were fully fed breast milk, comparing those fed directly at the breast (n = 59) vs those fed partially/completely by bottle (n = 63). Results Compared to infants fed formula only, those who were bottle-fed breast milk demonstrated significantly better cognitive performance on both the Bayley Scales of Infant and Toddler Development (Third Edition) at 2 years [adjusted mean difference (95% CI) 1.36 (0.32, 2.40)], and on the Kaufman Brief Intelligence Test (Second Edition) at 4.5 years [7.59 (1.20, 13.99)]. Children bottle-fed breast milk also demonstrated better gross motor skills at 2 years than those fed formula [1.60 (0.09, 3.10)]. Among infants fully fed breast milk, those fed directly at the breast scored higher on several memory tasks compared to children bottle-fed breast milk, including the deferred imitation task at 6 months [0.67 (0.02, 1.32)] and relational binding tasks at 6 [0.41 (0.07, 0.74)], 41 [0.67 (0.04, 1.29)] and 54 [0.12 (0.01, 0.22)] months. Conclusions Our findings suggest that nutrients in breast milk may improve general child cognition, while nursing infants directly at the breast may influence memory.

  • Development and relative validation of a short food frequency
           questionnaire for assessing dietary intakes of non-alcoholic fatty liver
           disease patients
    • Abstract: Purpose This work aimed to design and validate a novel short food frequency questionnaire (SFFQ) to assess habitual intakes of food items related to non-alcoholic fatty liver disease (NAFLD) in a cohort of European patients. Methods A 48-item SFFQ was created, with questions from existing FFQs and expert knowledge, emphasizing foods and nutrients implicated in NAFLD pathogenesis. Consenting, fibroscan-diagnosed, NAFLD patients completed the SFFQ during a short interview and were asked to complete a 4-day diet diary (4DDD) at home for return by mail. Nutritional intakes were assessed utilizing the myfood24™ food composition dataset and estimated energy requirements (EER) were calculated using sex-, age- and weight-specific equations. Agreement between the dietary instruments was assessed by Spearman correlations and Bland Altman analysis. Results Fifty-five patients completed both the SFFQ and the 4DDD within 30 weeks; 42 (76%) were diagnosed with simple steatosis, whereas 13 (24%) had biopsy-proven steatohepatitis; the majority were overweight or obese, with a median (25th; 75th percentile) BMI of 33.2 kg/m2 (29.3; 36.0). Reported energy intakes were well below EER with a median intake of 73% of requirements, suggesting widespread under-reporting. Significant correlations were observed between sugar (r = 0.408, P = 0.002), fat (r = 0.44, P = 0.001), fruits (r = 0.51, P = 0.0001) and vegetables (r = 0.40, P = 0.0024) measurements by the SFFQ and 4DDD. Bland Altman plots with regression analysis demonstrated broad comparability with the 4DDD for intakes of fat (bias − 13.8 g/day) and sugar (bias  + 12.9 g/day). Conclusions A novel SFFQ designed to be minimally burdensome to participants was effective at assessing dietary intakes in NAFLD patients.

  • Chocolate and risk of chronic disease: a systematic review and
           dose-response meta-analysis
    • Abstract: Purpose Evidence for the association between chocolate intake and risk of chronic diseases is inconclusive. Therefore, we aimed to synthesize and evaluate the credibility of evidence on the dose-response association between chocolate consumption with risk of all-cause mortality, coronary heart disease (CHD), stroke, heart failure (HF), type 2 diabetes (T2D), colorectal cancer (CRC), and hypertension. Methods Prospective studies were searched until July 2018 in PubMed, Embase, and Web of Science. Random-effects meta-analyses comparing highest versus lowest intake categories, linear, and non-linear dose-response analyses were conducted. The credibility of evidence was evaluated with the NutriGrade scoring-system. Results Overall, 27 investigations were identified (n = 2 for all-cause mortality, n = 9 for CHD, n = 8 for stroke, n = 6 for HF, n = 6 for T2D, n = 2 for hypertension and CRC, respectively). No associations with HF (RR 0.99, 95% CI 0.94, 1.04) and T2D (RR 0.94, 95% CI 0.88, 1.01) per each 10 g/day increase in chocolate intake were observed in the linear dose-response meta-analyses. However, a small inverse association for each 10 g/daily increase could be shown for the risk of CHD (RR 0.96, 95% CI 0.93, 0.99), and stroke (RR 0.90, 95% CI 0.82, 0.98). The credibility of evidence was rated either very low (all-cause mortality, HF, T2D, CRC or hypertension) or low (CHD, stroke). Conclusion Chocolate consumption is not related to risk for several chronic diseases, but could have a small inverse association with CHD and stroke. Our findings are limited by very low or low credibility of evidence, highlighting important uncertainty for chocolate–disease associations.
