To develop a convenient animal model of T2D by pretreatment with low-dose 10% w/v fructose (FRC) solution followed by the injection of low doses of streptozotocin (STZ) in Wistar rats. For this 8-week experimental study; rats were first fed a standard chow ad-libitum diet and either tap water (n=40) or 10% w/v FRC solution (n=40) for 4 weeks. Next, rats in each category were randomly allocated to 4 subgroups (n=10 each) of low-dose STZ (25,35, and 45 mg/kg). The final mean fasting blood sugar (FBG) of FRC+STZ45 (197±55...

It is becoming increasingly important to differentiate complex mixtures, especially in forensics. Cachaça, the most popular alcoholic beverage in Brazil, is made from distilled and fermented sugar cane juice. It contains a mixture of naturally occurring polyphenols known as tannins, whose composition is dictated by the type of wood used to age the beverage. These tannins can be differentiated in an Indicator Displacement Assay (IDA) using peptide-based ternary sensing ensembles. This investigation demonstrates a technique for fingerprinting the identity of the woods used to age cachaças...

The lgtF gene encodes a glucosyltransferase responsible for adding a glucose to the first sugar of heptose I in the synthesis of lipooligosaccharides (LOS). To study the function of lgtF, we constructed an lgtF mutant (ΔlgtF) from Haemophilus parasuis SC096 using a natural transformation system. A highly purified preparation of LOS from ΔlgtF (ΔlgtF-LOS) exhibited an obvious truncation in structure compared to the LOS of the wild-type SC096 strain (WT-LOS). The ΔlgtF-LOS also displayed a significantly reduced ability to induce inflammatory cytokine mRNA expression of tumor necrosis factor alpha (TNF-α), interleukin-1α (IL-1α), IL-1β, IL-6 and IL-8 in porcine alveolar macrophages (PAMs) in comparison with the WT-LOS...

A 10% excise tax on sugar sweetened beverages (SSBs) was implemented in Barbados in September 2015. A national evaluation has been established to assess the impact of the tax. We present a descriptive analysis of initial price changes following implementation of the SSB tax using price data provided by a major supermarket chain in Barbados over the period 2014-2016. We summarize trends in price change before and after the tax using year-on-year mean price per liter change between SSBs and non-SSBs. We find that prior to the tax, year-on-year price growth of SSBs and non-SSBs was very similar (approximately 1%)...

The nucleus accumbens (NAcc) is a forebrain region that may significantly contribute to the integration of taste and visceral signals during food consumption. Changes in dopamine release in the NAcc have been observed during consumption of a sweet taste and during compulsive consumption of dietary sugars, suggesting that NAcc dopaminergic transmission is strongly correlated with taste familiarity and the hedonic value content. NAcc core and shell nuclei are differentially involved during and after sugar exposure and, particularly, previous evidence suggests that dopamine D2 receptors could be related with the strength of the latent inhibition (LI) of conditioned taste aversion (CTA), which depends on the length of the taste stimulus pre-exposure...

Caffeine is a psychostimulant frequently consumed by adults and children, often in combination with high levels of sugar. Chronic pretreatment with either substance can amplify both amphetamine and cocaine-induced hyperactivity in rodents. The present study sought to elucidate whether age at the time of exposure to sugar and/or caffeine alters sensitivity to an acute illicit psychostimulant (methamphetamine, [METH]) challenge in adulthood. Adult and adolescent (Postnatal Day 35 on first day of treatment) male Sprague-Dawley rats were treated for 26 days with water, caffeine (0...

BACKGROUND: Diet is considered to be a key factor in symptom generation in Irritable Bowel Syndrome (IBS) and patients tend to exclude food products from their diet in pursue of symptom relief, which may impair diet quality. METHODS: We evaluated habitual dietary intake in IBS patients with regard to nutrients and food products using an extensive food frequency questionnaire. One hundred ninety-four IBS patients were compared to 186 healthy controls using multiple logistic regression analysis...

Short-chain fatty acids (SCFAs), which are the end products of carbohydrate fermentation in the gut, mainly contribute to energy metabolism in mammals. The amount of SCFAs produced during fermentation is an important parameter that characterizes the fermentation capacity of a system. This paper reports on the fermentation characteristics of exopolysaccharides (EPS) isolated from Fomitopsis castaneus Imaz, a wood-rot fungal species. We isolated and purified the main EPS fraction by freeze drying and DEAE-Sepharose fast flow chromatography...

BACKGROUND: Diet and activity are thought to worsen with urbanization, thereby increasing risk of obesity and chronic diseases. A better understanding of dietary and activity patterns across the urbanization divide may help identify pathways, and therefore intervention targets, leading to the epidemic of overweight seen in low- and middle-income populations. Therefore, we sought to characterize diet and activity in a population-based study of urban and rural residents in Puno, Peru. METHODS: We compared diet and activity in 1005 (503 urban, 502 rural) participants via a lifestyle questionnaire...

Tamr (dried dates) has a high sugar content, essential vitamins, and high nutrient density. Dairy products still are the most typical carriers of probiotic bacteria. Six treatments of bio-rayeb milk were manufactured from goat's milk fortified with 5%, 10%, 15%, 20%, and 25% Tamr using ABT-5 culture. Rayeb milk containing tamr had lower pH and fat and higher carbohydrate, total solids, dietary fiber, ash, total protein, water-soluble nitrogen, and total volatile fatty acids. Mixing tamr with bio-rayeb milk increased nutritional value by decreasing saturated fatty acids and increasing unsaturated fatty acids, oleic, linoleic, α-linolenic acids, and antioxidant activity values...

White rose petal extract (WRE) contains large amounts of phenolic compounds and is considered edible. In this study, red and white wines were prepared by the addition of WRE (0.10% or 0.25%, w/v), followed by fermentation at 25°C for 15 days. The fermentation profiles, colors, sensory test results, and antioxidant activities of wines were compared. As reported herein, the fermentation profiles such as the pH, CO2 production rate, and final ethanol concentration were not affected by the addition of WRE, but a slow consumption rate of sugar was observed in 0...

BACKGROUND: The Health Star Rating (HSR) is an interpretive front-of-pack labelling system that rates the overall nutritional profile of packaged foods. The algorithm underpinning the HSR includes total sugar content as one of the components. This has been criticised because intrinsic sugars naturally present in dairy, fruits, and vegetables are treated the same as sugars added during food processing. We assessed whether the HSR could better discriminate between core and discretionary foods by including added sugar in the underlying algorithm...

Epidemiological data provide strong evidence of dramatically increasing incidences of many autoimmune diseases in the past few decades, mainly in western and westernized countries. Recent studies clearly revealed that 'Western diet' increases the risk of autoimmune diseases at least partially via disrupting intestinal tight junctions and altering the construction and metabolites of microbiota. However, the role of high sucrose cola beverages (HSCBs), which are one of the main sources of added sugar in the western diet, is barely known...
