RESUMO

OBJECTIVES: Oral health can affect quality of life in all course of life, which is a key factor of general health. Dental caries, periodontitis and oral cancer are of the highest burden of oral diseases. Rising prevalence of soft drinks and alcoholic beverages consumption due to easy access and socio-demographic altering has increased the concerns on oral health. In this review our purpose was to show effects of the most consumed beverages on oral health in people older than 15 years. METHODS: The review was based on papers published in last 10 years, searched with combined key words related to types of drinks and specific oral health problems. We included 4 older studies due to lack of newer studies on subjected topics. RESULTS: Sugar-free soft drinks are found less cariogenic and erosive than regular versions in limited number of studies. Alcohol consumption is shown as one of the risk factors of prevalence and severity of periodontitis and is proven to have synergistic effects along with tobacco on oral cancer risk. Consumption of soft drinks and alcoholic beverages was related with tooth loss whether dental caries or periodontal diseases. CONCLUSION: There is good evidence for association between soft drinks and oral health problems, but still no clear answer exists about strength of association between sugar-free soft drinks and dental caries. Also the knowledge about influence of alcohol is inadequate. Since consuming style affects erosive potential of drinks manufacturers should be required to add some recommendations on labels about drinking style.

RESUMO

The aim of the present study was to compare the sensitivity and specificity of pain scales used to assess dentin hypersensitivity (DH). The preferred scale, and toothbrushing habits of participants were also investigated. This cross-sectional study was conducted with students and employees of a Brazilian Federal University who presented DH. The participants answered a questionnaire about their toothbrushing and drinking habits. Hypersensitive and non-sensitive teeth were submitted to tactile and ice stick stimuli. Then, the subjects marked their pain level in the visual analogue (VAS), numeric scale (NS), faces pain scale (FPS) and verbal evaluation scale (VES). DH was also assessed by Schiff scale (SS). The data were analyzed by Wilcoxon and Chi-Square tests, as well as by ROC curve. The mean age of the sample (56 women, 16 men) was 27.8 years. The most prevalent acidic beverage was coffee (36.0%) and the most preferred scale was the NS (47.2%). The pain level was statistically higher in teeth with DH compared to teeth without DH (p < 0.05). The accuracy ranged from 0.729 (SS) to 0.750 (NS). The highest sensitivity value was 81.9% for NS. The SS presented the highest specificity (91%). The visual analog, numerical, verbal evaluation, faces pain, and Schiff scales were accurate for DH diagnosis. The Schiff scale was the preferred scale for DH assessment.

RESUMO

AIM: The aim of this study was to assess the impact of acidic drink on the microhardness of different esthetic restorative materials. MATERIALS AND METHODS: Sixty samples (20 samples of each group) were prepared. group I: nanohybrid ormocer-based composite, group II: glasiosite compomer, and group III: nanoceramic composite. A cylindrical aluminum mold of 5 mm depth and 10 mm internal diameter was used to prepare the samples. All the esthetic restorative samples were submerged in 25 mL of acidic drink (Coca-Cola) for 10 minutes each day up to 15 days. The microhardness of each sample was measured using a Vickers diamond intender. These values were matched with baseline, 7th day, and 15th day for final microhardness values. RESULTS: The mean surface microhardness of 61.13 ± 0.82 was shown by group I, which was slightly more than that in group II (59.65 ± 1.16) and group III (59.22 ± 1.30). Analysis of covariance did not show any statistically significant difference between the groups. The samples in group III showed the highest reduction in surface microhardness value after immersion into acidic drink, followed by group II and group I on 7th day and 15th day. A statistically significant difference (p < 0.001) was found on 7th day. CONCLUSION: The present study concludes that the esthetic restorative material-nanohybrid ormocer-based composite-showed the finest behavior both before and after being dipped in the acidic drink followed next by glasiosite compomer and nanoceramic composite. CLINICAL SIGNIFICANCE: The various esthetic restorative materials with different physical characteristics and colors are marketed in numerous ways. Nevertheless, all dental restorative materials show surface degradation under acidic conditions over a period of time. So, it helps to know the surface microhardness changes of various esthetic restorative materials upon repeated exposure to acidic beverages.

RESUMO

Objective: To assess the prevalence and dental erosion risk factors in Mexican schoolchildren. Study design: A transversal and analytical study was conducted on 411 children aged 6 to 12 years old in a public primary school of Mexico City. The children's parents answered a standardized questionnaire about their risk factors, and the Smith and Knight index was applied to assess their dental erosion degree. Results: The prevalence of dental erosion was 62%. The odds ratio and X2 tests revealed that probiotic beverage consumption (OR 1.658; CI 95%: 1.106-2.485; p = 0.014), sports beverages (OR: 2.807; CI 95%: 1.129-6.983; p = 0.021), natural juices (OR: 3.344; CI 95%: 1.556-7.184; p = 0.003), fruits and snacks with hot peppers and lemon (OR: 1.594; CI 95%: 1.066-2.382; p = 0.023), and syrups (OR: 1.869; CI 95%: 1.060-3.296; p = 0.029) were all risk factors for dental erosion. Conclusions: This study indicated that a high existence of dental erosion, which mainly affects the primary molars, is related to the frequent consumption of beverages and foods with acidic pH levels.

RESUMO

The effects of ß-cyclodextrin (ß-CD), whey protein (WP), and soy protein (SP) on the color loss and degradation of anthocyanins in purple-fleshed sweet potato anthocyanin extracts (PFSPAEs) during thermal treatment and shelf-life storage in model beverage systems by performing chromaticity, degradation kinetics, and principal component analysis. Results showed that WP and SP improved the thermal stability of the PFSPAE, but WP accelerated the color loss of the extract. However, the addition of 25 mg/L SP improved the color and thermal stability of the anthocyanins when heated at 100 °C for 30 min. With regard to the shelf-life storage, the addition of SP and WP showed non-significant effect on the storage stability of the PFSPAE. However, the addition of 2500 mg/L ß-CD significantly improved the storage stability of the PFSPAE. In summary, our findings provide useful information on improving the thermal and storage stability of PFSPAEs in beverage systems using food biopolymers.

RESUMO

A novel dendritic silicon dioxide nanocomposite coated with a highly dispersed graphene-like boron nitride nanosheet (g-BN(x)@SiO2) was in-situ synthesized and employed as a solid-phase extraction material for the Rhodamine B (RhB) and Rhodamine 6G (R6G) enrichment in food samples prior to their quantitation by HPLC. The structures and morphologies of g-BN(x)@SiO2 were characterized by XRD, FTIR, BET and TEM. The adsorption performance and mechanism were investigated and showed an enhanced maximum adsorption capacity of 625 mg/g for RhB on the nanocomposite loaded with 1% of g-BN via a fast, spontaneous process. Under optimal extraction conditions, this method showed low detection and quantification limits (2.8 µg/L for RhB, 2.1 µg/L for R6G and 9.2 µg/L for RhB, 6.9 µg/L for R6G, respectively), good repeatability (RSD% <3.7%), and satisfactory spiked recoveries of 94.8%-103.1% for RhB and R6G in real chili powder and beverage. Therefore, the g-BN(1%)@SiO2-based materials possess significant potential.

RESUMO

Consortia of aerobic heterotrophic bacteria (AHB) have potential as sustainable microbial protein (MP) source in animal feed. A systematic screening of the nutritional value and safety of AHB biomass from full-scale activated sludge plants from 25 companies in the food sector was performed. The variable protein content (21-49%) was positively correlated with biomass-specific nitrogen loading rate and negatively with sludge retention time (SRT). Compared to the essential amino acid profile of soybean meal protein, AHB displayed an overall surplus of threonine and valine, and deficits in cysteine, histidine, lysine and phenylalanine. Histidine was positively correlated with bCOD/PO43- in the influent and valine, isoleucine and threonine with SRT. Most AHB samples were safe apropos heavy metals, polycyclic aromatic hydrocarbons and antibiotics. Some pesticides exceeded regulatory limits, necessitating mitigation. This work highlighted that the food sector can provide high-quality MP, while retrofitting existing activated sludge plants towards high-rate processes can increase AHB quality and productivity.

RESUMO

A water-soluble, long-term stable, poly(sodium-p-styrenesulfonate)-enhanced and d-penicillamine stabilized argentum nanoclusters (PSS-DPA-AgNCs) was synthesized by a one-step ultraviolet radiation combined with microwave heating method. The effects of different types of polyelectrolytes and energy suppliers on the AgNCs photo-luminescence performance were investigated in detail. The prepared AgNCs are exhibited to be viable fluorescent method for 2-Mercapto-3-butanol (2-M-3-B), 3-Mercapto-2-butanone (3-M-2-B) and silicate (SiO32-) determinations. The fluorescence (FL) of PSS-DPA-AgNCs is quenched with the addition of 2-M-3-B/3-M-2-B/SiO32- mainly originating from a static quenching process. The method can monitor 2-M-3-B/3-M-2-B by fluorometry with a linear response in the range of 0.33-90.0/0.33-80.0 µM and a 74/250 nM detection limit (at 3σ/slope). For the SiO32- assay, corresponding data are 3.33-100.0 µM and 278 nM. Moreover, the proposed method was successfully used for the assays of two food flavors in the steamed bread and soda drinks, and silicate in the mineral water samples respectively.

RESUMO

In this paper, a simple, sensitive and precise electroanalytical method was developed using flow injection analysis (FIA) with amperometric detection and reduced graphene oxide sensor for ascorbic acid determination in samples of multivitamin beverages, milk, fermented milk, and milk chocolate. The advantages of this sensor include a potential displacement of 450 mV and a 2-fold peak current increase for electrochemical oxidation of ascorbic acid, which resulted in a highly sensitive method. No interference of sample matrix was observed, avoiding solvent extraction procedures (samples were only diluted). The FIA allowed a high analytical frequency, approximately 96 injections per hour, together with adequate detection limit of 4.7 µmol L-1. Good precision (RSD < 7%) and accuracy (recoveries between 91 and 108%) evidenced the robustness of the method. The method was compared with ultra-fast liquid chromatography (UFLC) obtaining statistically similar results (95% confidence level). The ascorbic acid content in samples varied from 0.065 to 2.53 mmol L-1.

RESUMO

The hazardous and obesogenic food environment are major contributors to health loss in Aotearoa New Zealand. Here we consider the potential use of food taxes and subsidies to protect health in this country. We find that each one of the 14 recent systematic reviews on the tax and/or subsidy topic since 2015 in the scientific literature report that such interventions have favourable impacts from a health perspective. The New Zealand evidence we considered (n=12 studies since January 2010) is less definitive, but the pattern of results is consistent with the international evidence. Given this overall picture, the New Zealand Government should seriously consider such tax/subsidy interventions, potentially starting with a UK-style sugary drinks industry levy.

RESUMO

The energy-water nexus is a concept widely established but rarely applied to product and, in particular, to food and beverage products, which have a great influence on greenhouse gases emissions. The proposed method considers the main nexus aspects in addition to other relevant aspects such as climate change, which is deeply linked with energy and water systems, and assessing process as well as product. In this framework, this study develops an integrated index (IWECN) that combines life cycle assessment (LCA) and linear programming (LP) to assess energetic, water and climate systems, enabling the identification of those products with minors energetic and water intensity and climate change effects and helping to the decision-making process and to the development of eco-innovation measures. In this case, the product assessed was one bottle (70 cl) of gin and two main hotspots were identified: the production of the glass bottle and the energy requirements of the distillation stage. Based on that, several eco-innovation strategies were proposed: the use of photovoltaic solar energy as energy source and the substitution of the glass bottle by a plastic one and by a tetra brick. The nexus results indicated that the use of solar photovoltaic energy and plastic as bottle material was the best alternative decreasing 58% the IWECN value of the production of one bottle of gin. The sensitivity analysis presented a strong preference for photovoltaic solar energy in comparison with electric power and for the reduction of the glass bottle weight or its substitution by a plastic bottle. The use of the IWECN index is extendable to any product with the aim of facilitating the decision-making process in the development of more sustainable products to introduce them in new green markets.

RESUMO

Chinese herbal tea has a long history in China, and is one of the most consumed beverage products as of now. However, whether herbal tea can really promote health and be considered as a functional food is still a question. The objective of this work was to assess the beneficial effect of herbal tea on health using Drosophila as the model. Adding commercially available herbal tea to food could increase average life span of fruit flies for more than 50%. Further tests showed that the effect of herbal tea was not dependent on specific single ingredient. The present results suggest that Chinese herbal tea may have beneficial effects to human health.

RESUMO

Traditional boron affinity materials usually capture cis-diol-containing molecules under alkaline condition, but some cis-diol-containing molecules, such as polyphenols, are unstable and easy to be oxidized and degraded under alkaline condition. Teamed boronate affinity (TBA) can specifically capture cis-diol-containing molecules under neutral condition. However, the report about combination of TBA and magnetic nanoparticle for the extraction was rare. Here, we fabricated two kinds of teamed boronate affinity magnetic nanoparticles (TBAMP), including Fe3O4@TBAP and Fe3O4@SiO2@TBAP. Adsorption capacities of cis-diol-containing molecules on the latter were similar to these on the former, but the latter possessed more superior regeneration performance than the former. Therefore, the TBAMP with more superior regeneration performance was used as magnetic solid-phase extraction (MSPE) adsorbent for capturing polyphenols under neutral condition. The TBAMP MSPE was optimized in detail, and combined with high-performance liquid chromatography-mass spectrometry (HPLC-MS) for the simultaneous determination of 13 kinds of polyphenols from Flos Lonicerae Beverage. The proposed method showed low limit of detection between 0.01 and 0.20 ng mL-1. In blank Flos Lonicerae Beverage, 11 kinds of polyphenols ranged from 0.54 ng mL-1 to 52.99 ng mL-1 were detected. In the standard addition method, recoveries of cis-diol-containing polyphenols were between 85.7% and 102.1% with intra-day and inter-day relative standard deviation ranging from 3.2% to 5.1% and 5.3% to 7.3%, respectively.

RESUMO

In this work we propose the use of statistical mixture design in the construction of a biosensor device based on graphite oxide, platinum nanoparticles and biomaterials obtained from Botryosphaeria rhodina MAMB-05. The biosensor was characterized by electrochemical impedance spectroscopy. Under optimized experimental parameters by factorial design, the biosensor was applied to the voltammetric determination of chlorogenic acid (CGA) measured as 5-O-caffeoylquinic acid (5-CQA). The biosensor response was linear (R2 = 0.998) for 5-CQA in the concentration range 0.56-7.3 µmol L-1, with limit of detection and quantification of 0.18 and 0.59 µmol L-1, respectively. The new biosensing device was applied to quality control analysis based upon the determination of CGA content in specialty and traditional coffee beverages. The results indicated that specialty coffee had a significantly higher content of CGA. Principal component analysis of the voltammetric fingerprint of brewed coffees revealed that the laccase-based biosensor can be used for their discrimination.

RESUMO

Objectives. To identify the effect of a Breakfast in the Classroom (BIC) initiative on the foods and drinks students consume in the morning.Methods. Sixteen public schools in Philadelphia, Pennsylvania, that provide universal breakfast participated in a group randomized trial to examine the effects of BIC with complementary nutrition promotion between 2013 and 2016. Control schools (n = 8) offered breakfast in the cafeteria before school. Baseline data were collected from 1362 students in grades 4 to 6. Endpoint data were collected after 2.5 years. Students self-reported the foods and drinks they consumed in the morning.Results. At endpoint, there was no effect of the intervention on breakfast skipping. Nearly 30% of intervention students consumed breakfast foods or drinks from multiple locations, as compared with 21% of control students. A greater proportion of intervention students than control students consumed 100% juice, and a smaller proportion consumed sugar-sweetened beverages and foods high in saturated fat and added sugar.Conclusions. A BIC initiative led to improvements in the types of foods and drinks students consumed in the morning. However, the program did not reduce breakfast skipping and increased the number of locations where students ate.

RESUMO

Packaging used for beverages, such as soft drinks, juices, and beers, is widely consumed worldwide. The manufacture of this packaging involves energy consumption, even when made with recycled material. The sum of all energies required to produce the packaging is considered the incorporated or embodied energy. In this work, the embodied energy used to manufacture six common types of beverage packaging was analyzed. For this purpose, the average percentage of material recycling in Brazil and the United States of America (USA) was considered since the energy incorporated is quite different when recycling is used. A calculation methodology was developed to estimate the embodied energy in each type of packaging in Brazil and the USA. For a more appropriate comparison, the embodied energy per volume was calculated. Comparing the embodied energy per volume, aluminum packaging, when mostly recycled, is the packaging that has the lowest embodied energy per liter of beverage. This study highlights the importance of recycling to produce packaging with less embodied energy and opens perspectives for environmentally more favorable attitudes regarding the choice of beverage packaging materials.

RESUMO

Objective: To evaluate whether midlife consumption of sugar-sweetened beverages (SSBs), including juices and soft drinks, were associated with late-life cognitive impairment in Chinese adults. Methods: Follow up was conducted for participants from Singapore Chinese Health Study, a population-based prospective cohort, for 16-23 (mean 20) years. The information about their SSBs consumption were collected at baseline survey from 1993 to 1998 by using a validated food frequency questionnaire and their cognition status were evaluated by using a Singapore-modified Mini-Mental State Examination Scale in the 3(rd) follow-up visit during 2014- 2016. Multivariable logistic regression models were used to estimate the ORs and 95%CIs. Results: A total of 16 948 participants were included in the analysis and 2 443 of them were identified as cognitive impairment using education-specific cutoffs. Sex, age, ancestral home, education level, physical activity level, total diet fiber intake level, BMI, alcohol drinking were significantly associated with cognitive impairment (P<0.05). After adjusted the above variables, potential dietary variables and disease status, no significant association was observed between SSBs consumption and cognitive impairment (P>0.05). Compared with those who never or hardly ever drank soft drinks, no significant differences in cognitive impairment risk were observed for those who drank soft drinks 2 or more times a week (OR=0.91, 95%CI: 0.77-1.08), those who drank 1 time a week (OR=1.00, 95%CI:0.82-1.23) and those who drank 1-3 times a month (OR=0.94, 95%CI: 0.80-1.09) (trend P=0.306). Compared with those who never or hardly ever drank juices, no significant differences in cognitive impairment risk were observed for those who drank juices 2 or more times a week (OR=1.03, 95%CI:0.88-1.20), those who drank 1 time a week (OR=0.96, 95%CI: 0.82-1.12) and those who drank 1-3 times a month (OR=0.94, 95%CI: 0.82-1.08) (trend P=0.930). No significant interactions were found with age, sex, and BMI status. Conclusion: SSBs consumption in midlife was not significantly associated with risk of late-life cognitive impairment in Singaporean Chinese adults with relatively low consumption levels. Further researches are needed to verify the results.

RESUMO

The functionalization of covalent organic frameworks (COFs) enhances chemical properties and expands future applications. Herein, a facile strategy for sulfoacid-functionalized COF is presented through post-modification of covalent triazine frameworks (CTFs) platform. The magnetic solid phase extraction (MSPE) material is obtained by anchoring in situ Ni particles on CTF support (Ni/CTF-SO3H) possessing a dual retention mechanism combining hydrophilic-lipophilic-balance (HLB) and cation-exchange interaction. We established the (Ni/CTF-SO3H)-MSPE method for selectively enriching carbendazim (CBZ) and thiabendazole (TBZ) from food samples and reducing matrix effect simultaneously. The method detection limit is 1.23-7.05 µg kg-1 for CBZ and TBZ in vegetable, fruit and juice samples, determined by high-performance liquid chromatography-ultraviolet detector. The recoveries of spiked CBZ and TBZ in the samples are 80.2-115.1% and RSDs 6.0-11.4%, depending on both analytes and samples. Our work provides a unique perspective in the development of functionalized COFs as a versatile HLB/cation-exchange mixed-mode SPE sorbent for extraction of basic analytes in complex matrix.

RESUMO

Kombucha, a fermented tea generated from the co-culture of yeasts and bacteria, has gained worldwide popularity in recent years due to its potential benefits to human health. As a result, many studies have attempted to characterize both its biochemical properties and microbial composition. Here, we have applied a combination of whole metagenome sequencing (WMS) and amplicon (16S rRNA and Internal Transcribed Spacer 1 [ITS1]) sequencing to investigate the microbial communities of homemade Kombucha fermentations from day 3 to day 15. We identified the dominant bacterial genus as Komagataeibacter and dominant fungal genus as Zygosaccharomyces in all samples at all time points. Furthermore, we recovered three near complete Komagataeibacter genomes and one Zygosaccharomyces bailii genome and then predicted their functional properties. Also, we determined the broad taxonomic and functional profile of plasmids found within the Kombucha microbial communities. Overall, this study provides a detailed description of the taxonomic and functional systems of the Kombucha microbial community. Based on this, we conject that the functional complementarity enables metabolic cross talks between Komagataeibacter species and Z. bailii, which helps establish the sustained a relatively low diversity ecosystem in Kombucha.

RESUMO

Dietary habits are important factors in our lifestyle, and confer both susceptibility to and protection from a variety of human diseases. We performed genome-wide association studies for 13 dietary habits including consumption of alcohol (ever versus never drinkers and drinks per week), beverages (coffee, green tea and milk) and foods (yoghurt, cheese, natto, tofu, fish, small whole fish, vegetables and meat) in Japanese individuals (n = 58,610-165,084) collected by BioBank Japan, the nationwide hospital-based genome cohort. Significant associations were found in nine genetic loci (MCL1-ENSA, GCKR, AGR3-AHR, ADH1B, ALDH1B1, ALDH1A1, ALDH2, CYP1A2-CSK and ADORA2A-AS1) for 13 dietary traits (P < 3.8 × 10-9). Of these, ten associations between five loci and eight traits were new findings. Furthermore, a phenome-wide association study revealed that five of the dietary trait-associated loci have pleiotropic effects on multiple human complex diseases and clinical measurements. Our findings provide new insight into the genetics of habitual consumption.
