Comparative Effect of Adding Synthetic Citric Acid to Natural Lemon Juice (Citrus aurantiifolia) on the Stability of Hibiscus Drinks Stored at 4°C and 37°C

The general objective of the work is to compare the effect of the addition of synthetic citric acid compared to the addition of natural fruit juice of Citrus aurantiifolia on the conservation of drink based on red chalice H. sabdariffa. The tests were carried out over a period of 5 weeks at 4°C and 37°C with seven batches of beverage samples prepared at the rate of a calyx/water ratio of 1/40 (kg·kg-1) and added respectively citric acid at 1, 2 and 4 g·L-1 and lemon juice at 10, 20 and 40 mL·L-1. The characterization of the different batches of beverages was carried out from day one. A follow-up of the residual anthocyanin content and the intensity of the red coloring were carried out over five weeks. The anthocyanin concentration was determined by the pH-differential method. The red color degradation index is determined based on the CIELAB color system (L*, a*, b* and L*). R and Minitab 18 software was used for data processing. The results of the monitoring of the parameters showed that the concentration of 1 g AC L-1 retains 2.7 mg more of the anthocyanins than adding 10 mL JC L-1 and longer maintains red color when stored at 4°C and 37°C/5 weeks. The 2 g AC L-1 and 4 g AC L-1 ratios have the same effects as the addition of 20 and 40 mL of lemon juice, all accelerating the degradation of anthocyanins and the red color. After 5 weeks of storage at 37°C, the effect of the temperature combined with the increase in the acidity of the samples (2 to 4 g AC L-1 and 20 to 40 ml JC L-1), have accelerated the total disappearance of the red color on all samples.

Violent and Risk-Taking Behaviors Associated with Intake of Energy Drinks Mixed with Alcohol and Perceptions of This Consumption among Children and Adolescents in Costa Rica

Introduction: The consumption of energy drinks and its mix with alcohol has been associated with negative and violent behaviors in youngsters. Objective: To determine the risk-taking behaviors associated with the consumption of energy drinks mixed with alcohol in Costa Rican adolescents. Methods: A mixed cross-sectional study was performed with a population of 2667 students of 64 educative centers in 2016. Descriptive statistics were performed with the program SPSS 20.0 and a value of p < 0.05 was considered significant. Results: The third part of the study population is usually a consumer of energy drinks (30%) and 3% make use of drinks mixed with alcohol. The children and adolescents, who consume energy-alcohol mixed drinks, are more likely to present risk-taking behaviors than those who do not consume these mixed beverages: combined use of medicines to get high;cocaine consumption, consumption of cement/glue, consumption of marijuana, physical violence (fighting), use of weapons, suicidal ideation, deliberate self-harm, low educational expectation, sexual intercourses, cyberbullying and school apathy. The students perceived the intake of energy beverages as of low risk for their health. They also agree that frequent consumption is because drinks have good flavors and nice logo designs and the ability to stay awake and with more energy for longer periods of time in order to improve in academic homework, sports performance and to endure more the consumption of alcoholic beverages. Conclusions: Public health policies should consider controlling the publicity aimed to children and adolescents regarding the marketing of energy and alcoholic drinks.

Effects of energy and sports drinks on tooth structures and restorative materials

Sports and energy drinks are consumed by more peoplethan ever. Sports and energy drinks may enhance physical resistance, stimulate metabolism, prevent rehydration and replace electrolytes during high activity efforts. However, these drinks often have a low pH and are acidic, which can erode enamel and dentin, and increase dentine hypersensitivity. In addition to the adverse effects of sports and energy drinks on tooth structures, they often have the potential to damage restorative materials. These drinks often contain artificial colors which have potential to discolor resin composite materials and glass ionomers. The acidic nature of these drinks could also lead to a degradation, increase in wear, and roughening of the surface of the restorative materials. Many of the negative consequences of sport and energy drinks can be related to their overconsumption among children and teenagers. Patients should be advised to have a healthy diet, and consume soft and energy drinks in moderation, to avoid any negative dental or health consequences. The overconsumption of sports and energy drinks which are high in sugar and have the lowest pH are most likely to cause avoidable dental problems.

Sleep quality, sleep patterns and consumption of energy drinks and other caffeinated beverages among Peruvian college students

Objectives: To evaluate sleep quality in relation to lifestyle characteristics including consumption of energy drinks and other caffeinated beverages among Peruvian college students. Methods: A total of 2458 college students were invited to complete a self-administered questionnaire that collected information about a variety of behaviors including consumption of energy drinks, caffeinated and alcoholic beverages. The Pittsburgh Sleep Quality Index (PSQI) was used to assess sleep quality. Logistic regression procedures were used to estimate odds ratios (OR) and 95% confidence intervals (95% CI) for poor sleep quality in relation to lifestyle characteristics. Results: A total of 965 males and 1493 female students were enrolled in the study. 52.0% of males and 58.4% of females experienced poor sleep quality (p = 0.002). Females (OR = 1.28;95% CI 1.08-1.51) and those who reported consuming ≥3 stimulant beverages per week (OR = 1.88;95% CI 1.42-2.50) had higher odds of poor sleep quality. Students who consumed 1-19 alcoholic beverages monthly (OR = 1.90;95% CI 1.46-2.49) had a higher odds of long sleep latency. Consumption of ≥3 stimulant beverages per week was associated with daytime dysfunction due to sleep loss (OR = 1.45;95% CI 1.10-1.90), short sleep duration (OR = 1.49;95% CI 1.14-1.94), and use of sleep medication (OR = 2.10;95% CI 1.35-3.28). Conclusions: Consumption of energy drinks, other caffeinated beverages and alcoholic beverages are risk factors of poor sleep quality. Increased awareness of these associations should promote interventions to improve students’ lifestyle habits, including consumption of alcoholic and caffeinated beverages, and overall health.

Effects of energy drinks on the cardiovascular system

Throughout the last decade, the use of energy drinks has been increasingly looked upon with caution as potentially dangerous due to their perceived strong concentration of caffeine aside from other substances such as taurine, guarana, and L-carnitine that are largely unknown to the general public. In addition, a large number of energy drink intoxications have been reported all over the world including cases of seizures and arrhythmias. In this paper, we focus on the effect of energy drinks on the cardiovascular system and whether the current ongoing call for the products' sales and regulation of their contents should continue.

Patterns of Caffeinated Energy Drinks Consumption among Adolescents and Adults in Hail, Saudi Arabia

Caffeinated energy drinks have become more popular in the last decades, especially amongst adolescents and young adults in different parts of the globe. The study aims to investigate the frequency of energy-drink consumption and associated factors in an arbitrary group of adults and adolescents living in Hail/Saudi Arabia. A cross-sectional study was conducted and included which randomly selected 1062 participants (867 males and 195 females) from universities, colleges, middle-to-higher schools and social settings. Data collection was conducted using a self-administered standard tested questionnaire. The current study revealed about 46% had drunk energy drinks, while about 54% did not ever drink energy drinks. Out of the energy drinks consumers, 37% started drinking during the primary school, 64% consumed energy drinks on a daily basis, and 44% consumed two or more cans per day. Reasons behind not taking energy drinks were the belief that they are unhealthy drinks (about two-thirds of non-drinkers), and lack of curiosity for energy drinks (18%). Other reasons such as unaccepted taste, thought to be obesogenic, and the possibility of getting addicted were also reported. From all participants, only 23% and 4% knew about the presence of caffeine and taurine, respectively, in energy drinks. Unreliable resources were the major sources of knowledge about energy drinks and their health effects. Awareness of community about the ingredients and potential hazards of energy drinks should be raised and encouraged by designing and implementing educational programs.

Glutamate and Caffeine intake of Some Snacks and Drinks in Saudi Arabia

The aim of this study was to estimate the intake level of glutamate and caffeine from some snacks and drinks. The survey was carried out during 2008 to 2009 in 3 selected governorates (Al-Hassa, Al- Katif and AD-Dammam) localized in the eastern area of Saudi Arabia. The age of study participants (298) was ranged between less than 4 – over 30 years. The snacks and drinks consumption data were gathered and calculated using the frequency methods. Forty nine samples of snacks and beverages were analyzed by High Performance Liquid Chromatography (HPLC) for glutamate and caffeine contents. The results indicated that total intake of snacks, chocolates and drinks were significantly correlated (spearman r = 0.856, 0.591, 0.943, p = 0.0) with total intake of glutamate and caffeine. The mean of caffeine intake was 40.4± 44.5 mg, while the mean of glutamate intake was 0.134± 0.146 mg. The highest concentration of glutamate was in Pringles with Ketchup (0.420), Bugles Smoking BBQ (0.660) and Indomie with Vegetables (0.860). The high caffeine concentrations of Kit Kat, Ulker and Galaxy samples were 166, 165.5, and 134.5 mg/kg respectively, while the beverages, the high caffeine concentrations were presented in energy drinks like Red bull (345.5), Power Horse (339.0) and Bugzy(333.0) mg/L. The children aged between 4– 8 were the most consumers of snacks which containing glutamate, while the adolescents consumed more chocolates and beverages which containing caffeine. These finding suggests that consumption of salty snacks, and sugar-sweetened beverages is mounting between important categories in the community, so interventions focusing on increasing physical activity and fruit and vegetable consumption will have an impact on obesity control and promoting health.

Consumption Pattern of Energy Drinks by University of Ibadan Students and Associated Health Risks Factors

Energy drinks are non alcoholic, carbonated beverages claimed to give extra burst of energy for daily obligation. They contain some form of legal stimulants and vitamins which are meant to give consumers short term boost in energy and increase mental alertness. Energy drinks enjoy patronage especially among higher institution students in Nigeria, but little is known about the consumption pattern and possible health risks to consumers. This study was carried out to determine the contribution of four commonly consumed energy drinks to energy intake of University of Ibadan students and the associated health risk factors. A descriptive cross-sectional survey of energy drinks consumption was carried out using a four-stage systematic random sampling technique to select 307 students from six out of nine halls of residence for Undergraduates and the two Postgraduate halls. A validated semi-structured, self-administered questionnaire was used to collect information on socio-demographic characteristics, consumption pattern and frequency, and factors influencing consumption of energy drinks. Samples of the four most commonly consumed energy drinks by the students (Power Horse, Emerge, Red Bull and Matador brands) were purchased from different stores within and around the University of Ibadan campus. Composite samples of all the four energy drinks (with at least six months expiration date) were analysed for physico- chemical characteristics, gross energy, minerals and B-vitamins content in triplicate using standard methods of AOAC. Data were analysed using descriptive statistics and one way ANOVA, and level of significance set at p < 0.05. Respondents mean age was 23.1 ± 4.6 years, 79.2% were undergraduates and 51.1% were female. Majority (74.6%) of respondents had ever taken energy drinks prior to the study, 42.4% reported consuming at least one can in a week, and 52.1% consumed 1 can at a sitting. Reasons for consumption included to increase: energy (48.2%), mental alertness (18.6%) and athletic performance (9.5%). Reported side effects were: insomnia (14.0%), frequent urination (12.2%), dehydration (11.3%), anxiety (9.1%), heart palpitation (3.5%). Frequency of consumption was significantly associated with gender (p < 0.05). Titratable acidity, total solids and pH of energy drinks ranged between 7.57 ± 0.60 - 8.28 ± 0.08, 7.57 ± 0.60 - 11.42 ± 0.31, and 3.36 ± 0.08 - 3.81 ± 0.12 respectively. Glucose, sucrose, and gross energy content ranged between 7.77 ± 0.01 - 7.89 ± 0.01 g, 22.61 ± 0.07 - 23.74 ± 0.09 g, and 43.59 ± 0.38 - 48.89 ± 0.28 kcal/100g respectively. Few respondents knew about the ingredients and potential health risks associated with energy drink consumption. All the four drinks had acidic pH, hence nutrition education on reduction of energy drink consumption is needed among these students.

Measurement of Radioactivity in Carbonated Soft Drinks and Annual Dose Assessment

A set of measurements have been conducted, using gamma spectrometry technique, in order to determine the activity-level in some carbonated soft drinks. The obtained activity is about 0.18 ± 0.07 Bq/l for 137Cs, whereas it is less than 0.13, 0.18 and 4.51 Bq/l respectively for 212Pb, 214Pb and 40K. The total average annual dose is about 3.49, 1.69 and 1.68 μSv/y respectively for 7 - 12, 12 - 17 and >17 years old person leading to a radiological risk about 0.142 for adolescent and adults. The obtained results show no significant radiation dose and radiation hazard on human health due to the consumption of these carbonated soft drinks.

Energy Drinks Do Not Improve Le Parkour Performance: A Randomized Controlled Study

Le Parkour is a sport where the athletes transpose common day-to-day obstacles in the best possible way. This sport demands elements like strength, focus and decision making;elements supposedly affected by energy drinks, with performance improvement. The aim of this study was to investigate the effects of energy drink ingestion on Le Parkour athlete’s performance. Twelve male amateur athletes, mean age of 23.5 ± 2.74, took part in this randomized, double-blind, placebocontrolled study. Subjects were randomly assigned to drink: 250 ml of energy drink, 500 ml of energy drink or placebo. Forty minutes after the beverage consumption, they were evaluated in a specific circuit performance test (time to complete the circuit) followed by a perceived exertion and a circuit technical difficulty evaluation. We also evaluated heart rate in 3 different moments: rest, pre-circuit and post-circuit. All variables were collected in 3 different experimental days. Time, perceived exertion and technical difficulty were higher in the first day compared to the others. Heart rate did not show a difference when we compared the days. Drinking one or two cans of an energy drink did not improve performance of Le Parkour athletes in a sport specific test. It also did not change heart rate or perceived exertion.

Effects of Gaseous Drinks in Wistar Rats Esophagus

The consumption of beverages and processed foods, mainly soft drinks, has been incorporated into the usual diet of children, adolescents and adults frequently in recent years. The present study aimed to study the effects of carbonated drinks on Wistar rats, based on the macroscopic and histological morphology of the esophagus. Fifteen Wistar rats were divided into three groups: control group;group fed with ration and cola-type refrigerant ad libitum and group fed with ration and gas industrialized water ad libitum, for a trial period of 90 days. For histopathology and morphology, the esophagus was removed, prepared in slides and stained with hematoxylineosin. Images of the sections were captured for analysis and classification of the inflammatory infiltrate. For morphometry, ten grid fields of 100 points were evaluated in the 40x eyepiece, totaling 3000 points per animal. The results demonstrate that the refrigerant treatment induced the following structural changes in the rats: significant reduction of weight in relation to the control group;inflammatory infiltrate predominantly diffuse mild to moderate and tissue edema. The rats treated with carbonated water had similar results to the control, besides signs of healing and tissue repair.

Soft drinks consumption and nonalcoholic fatty liver disease

Nonalcoholic fatty liver disease(NAFLD) is a common clinical condition which is associated with metabolic syndrome in 70% of cases.Inappropriate dietary fat intake,excessive intake of soft drinks,insulin resistance and increased oxidative stress combine to increase free fatty acid delivery to the liver,and increased hepatic triglyceride accumulation contributes to fatty liver.Regular soft drinks have high fructose corn syrup which contains basic sugar building blocks,fructose 55% and glucose 45%.Soft drinks are the leading source of added sugar worldwide,and have been linked to obesity,diabetes,and metabolic syndrome.The consumption of soft drinks can increase the prevalence of NAFLD independently of metabolic syndrome.During regular soft drinks consumption,fat accumulates in the liver by the primary effect of fructose which increases lipogenesis,and in the case of diet soft drinks,by the additional contribution of aspartame sweetener and caramel colorant which are rich in advanced glycation end products that potentially increase insulin resistance and inflammation.This review emphasizes some hard facts about soft drinks,reviews fructose metabolism,and explains how fructose contributes to the development of obesity,diabetes,metabolic syndrome,and NAFLD.

Influence of Drinking Conditions on Alcohol Metabolism in Healthy Men with <i>ALDH</i>2*1/*1 Genotype: Comparison between Different Alcoholic Drinks with or without Meal

The influence of drinking conditions on alcohol metabolism and drunkenness was investigated in healthy men with ALDH2*1/*1 genotype aged from 40 to 60 who were occasional or habitual drinkers. The investigation was performed by open intersection competitive drinking tests at an ethanol dose of 0.32 g/kg under 4 different drinking conditions: beer without a meal [B(–)], shochu (a distilled spirit) without a meal [S(–)], beer with a meal [B(+)] and shochu with a meal [S(+)]. The blood alcohol concentration (BAC) and BAC-AUC (area under the curve) were lower in the B(–) than in the S(–). The blood acetaldehyde concentration (BAcH) and the serum acetate concentration (SAce) were also lower in the B(–) than in the S(–). The meal markedly decreased BAC, BAC-AUC and BAcH-AUC for both alcoholic beverages. Subjective drunkenness was stronger in order of B(+) + in liver cells, was higher in the S(–) than in the B(–), and was decreased by the meal for both alcoholic beverages. These results suggested that glucide increase the rate of alcohol metabolism by supplying pyruvic acid to decrease the ratio of NADH/NAD+, which lowers BAC and relieves drunkenness. Thus, the intake of glucide calories while drinking is important to reduce the pharmacological and toxicological actions of alcohol.

Collaborative Efforts and Strategies for Cholera Outbreak Control in Garissa County, Kenya: Implementation of Water Quality Monitoring Interventions

A multi-faceted Case Area Targeted Intervention (CATI) approach emphasizing the integration of Water, Sanitation and Hygiene (WASH) interventions and Oral Cholera Vaccine (OCV) campaign was employed to respond to the outbreak of cholera in Garissa County. Drinking water sources in areas heavily impacted by cholera were systematically mapped and tested for microbiological quality. The quality assessment was carried out in April 2023 during an ongoing cholera outbreak in the county. A total of 109 samples were collected and tested for thermotolerant coliforms and other in situ parameters. The finding revealed that more than 87% of the samples did not meet the World Health Organization (WHO) standard for thermotolerant coliforms;and 30% had turbidity values above the recommended threshold values. None of the 109 samples had any traceable residual chlorine. Following these findings, the county government implemented the targeted interventions which resulted in a positive impact in the fight against cholera. The WHO supported key interventions which included capacity building in water quality monitoring and prepositioning of critical WASH commodities to the cholera affected areas.

Fate and Behavior of Tetracycline Resistance Genes in Activated Carbon Adsorption

The accessibility of tetracycline resistance gene (tetG) into the pores of activated carbon (AC), as well as the impact of the pore size distribution (PSD) of AC on the uptake capacity of tetG, were investigated using eight types of AC (four coal-based and four wood-based). AC showed the capability to admit tetG and the average reduction of tetG for coal-based and wood-based ACs at the AC dose of 1 g·L-1 was 3.12 log and 3.65 log, respectively. The uptake kinetic analysis showed that the uptake of the gene followed the pseudo-second-order kinetics reaction, and the uptake rate constant for the coal-based and wood-based ACs was in the range of 5.97 × 10-12 - 4.64 × 10-9 and 7.02 × 10-11 - 1.59 × 10-8 copies·mg-1·min-1, respectively. The uptake capacity analysis by fitting the obtained experiment data with the Freundlich isotherm model indicated that the uptake constant (KF) values were 1.71 × 103 - 8.00 × 109 (copies·g-1)1-1/n for coal-based ACs and 7.00 × 108 - 3.00 × 1010 (copies·g-1)1-1/n for wood-based ones. In addition, the correlation analysis between KF values and pore volume as well as pore surface at different pore size regions of ACs showed that relatively higher positive correlation was found for pores of 50 - 100 Å, suggesting ACs with more pores in this size region can uptake more tetG. The findings of this study are valuable as reference for optimizing the adsorption process regarding antibiotic resistance-related concerns in drinking water treatment.

Assessment of Nitrates and Nitrites in Borehole Water from the Southern and the Northern Region of Côte d’Ivoire (West Africa)

This study aimed to evaluate the quality of water from village boreholes by measuring physicochemical parameters such as nitrates, nitrites, and total organic carbon (TOC). Forty-five (45) village pumps from the Southern (Basse Côte) and the Northern (Korhogo) region of Cte d’Ivoire (west Africa) were sampled. Physicochemical parameters such as temperature, pH, conductivity at 25˚C, and turbidity were determined in situ, while nitrite and nitrate were analyzed according to ISO 10304-1 (2007) standard and total organic carbon (TOC) by NF EN 1484 (1997) standard. The results showed that the borehole waters of the Basse Côte and Korhogo analyzed are acidic, with an average temperature of 27.51˚C ± 0.16˚C and 29.95˚C ± 0.51˚C respectively for the Basse Côte and Korhogo regions. The borehole waters of the Basse Côtedo not contain nitrites, while those of Korhogo have average nitrite contents of 0.32 mg/l. The average nitrate rate in the waters of the Basse Côte and Korhogo are 12.08 ± 2.11 mg/l and 11.03 ± 3.18 mg/l respectively. The average TOC concentration of the waters of the Basse Côte is 1.28 ± 0.32 mg/l and that of Korhogo is 0.56 ± 0.09 mg/L. The study showed that the borehole waters of the Basse Côte and Korhogo have average temperatures between 27.4˚C and 29.95˚C with a slightly acidic pH value and acceptable salinity. The TOC concentrations obtained at the different sampling points were all below the French standard (2 mg/L) except for certains pumps of the Basse Côte. The water samples from the Basse Côte were devoid of nitrite. On the other hand, those from Korhogo revealed the presence of nitrite. Also, the borehole waters of the regions of the Basse Côte and Korhogo contain relatively high nitrate contents, presumably due to anthropometric activity. Overall, our study on the quality of drinking water showed that the waters analyzed are in compliance with international standards and safe for consumption.
