Is soft drink consumption associated with gestational hypertension? Results from the BRISA cohort

It is still unknown whether excessive consumption of sugar-sweetened beverages may be linked to gestational hypertensive disorders, other than preeclampsia. This study investigated the association between soft drink consumption and hypertension during pregnancy, analyzing the relationship from the perspective of counterfactual causal theory. Data from pregnant women of the BRISA cohort were analyzed (1,380 in São Luis and 1,370 in Ribeirão Preto, Brazil). The explanatory variable was the frequency of soft drink consumption during pregnancy obtained in a prenatal interview. The outcome was gestational hypertension based on medical diagnosis, at the time of delivery. A theoretical model of the association between soft drink consumption and gestational hypertension was constructed using a directed acyclic graph. Marginal structural models (MSM) weighted by the inverse of the probability of soft drink consumption were also employed. Using Poisson regression analysis, high soft drink consumption (≥7 times/week) was associated with gestational hypertension in São Luís (RR=1.48; 95%CI: 1.03-2.10), in Ribeirão Preto (RR=1.51; 95%CI: 1.13-2.01), and in the two cohorts combined (RR=1.45; 95%CI: 1.16-1.82) compared to lower exposure (<7 times/week). In the MSM, the association between high soft drink consumption and gestational hypertension was observed in Ribeirão Preto (RR=1.63; 95%CI: 1.21-2.19) and in the two cohorts combined (RR=1.51; 95%CI: 1.15-1.97), but not in São Luís (RR=1.26; 95%CI: 0.79-2.00). High soft drink consumption seems to be a risk factor for gestational hypertension, suggesting that it should be discouraged during pregnancy.

Prevalence Of Carbonated Soft Drink Consumption And Associated Factors Among Malaysian Adolescents: A Nationwide Cross-Sectional Study 2017

@#Carbonated soft drinks (CSD) consumption is one of the contributing factors to weight gain, dental caries and non-communicable diseases among adolescents. This study aims to determine CSD consumption among Malaysian adolescents and their associated factors. The Adolescent Health Survey 2017, was a nationally representative survey sampled school-going adolescents aged 13 to 17 years. Findings reported that 36.9% of adolescents reported CSD consumption at least once daily in the past 30 days, and the prevalence was higher than a similar study conducted in 2012. Boys, schools in rural areas, lower secondary schoolers, not physically active, consuming fast food, having food insecurity, and truancy problem reported significantly higher odds of consuming CSD compared to their counterparts. By ethnicity, Bumiputera Sarawak adolescents showed the highest odds of consuming CSD and followed by Bumiputera Sabah. Thus, interventions to limit CSD consumption among Malaysian adolescents should consider the factors highlighted in this study.

Assessment of body mass index and prevalence of obesity among undergraduate medical students: an observational study in a tertiary care teaching hospital of Madhya Pradesh

Background: Obesity is the major cause of various non-communicable diseases including diabetes mellitus, hypertension. The modifiable factors like stress, sedentary life, consumption of soft drinks and fast foods and lack of physical activity are responsible for it. Objective: to find dietary pattern, physical activity and status of overweight and obesity among medical students.Methods: It was a cross sectional observational study conducted on MBBS undergraduates studying in a g medical college at Sagar district of Madhya Pradesh, India. Out of nearly 500 medical students studying in different semesters, 300 students were participated in the study though the required sample size was 184 only. Structured questionnaire for interview, calibrated portable weight scale for weight measurement and stadiometer for height measurement were used.Results: The students were categorised into underweight, normal and overweight/obese on the basis of their calculated BMI (body mass index) value as per norms of World health organization for south Asian populations. 26.7% medical students were found to be overweight or obese based on BMI cut off value 23.00 kg/m2. There was lack of inclusion of fresh fruits and green vegetables in regular diet in 50% and nearly 95% of medical students respectively. The low level of physical activity was found in more than 85% of the medical students.Conclusions: The involvement of medical students in physical and sports activities is dire need for their good health.

Effects of consumption of soft drinks on the muscular morphology of animals submitted to concurrent training / Efecto del consumo de bebidas refrescantes en la morfología muscular de animales sometidos a entrenamiento concurrente

The consumption of industrialized foods and beverages contributes to the increase in body weight and manifestation of diverse illnesses. Among these industrialized products, soft drinks can be mentioned, which when consumed in large quantities can contribute to weight gain and the emergence of chronic non-communicable diseases such as hypertension, diabetes, and obesity. In terms of performance, several training protocols have been used, among which concurrent training is presented as a tool that can aid in the control of body weight and muscle development. Thus, the identification of dietary factors, as well as the use of appropriate training methods, can be essential factors in the increase in physical performance. To study the effects of concurrent training on the skeletal muscles of animals submitted to soft drink consumption. In the present study, 32 male rats were used, of the Wistar breed, in the post-weaning biological phase (30 days). The animals performed a concurrent training protocol. Forty-eight hours after the final training session, the animals were submitted to a surgical procedure to remove samples of gastrocnemius muscle. After preparation of the histological slides, the muscle fibers of the different groups of animals were measured. The median values for the minimum diameter of muscle fibers presented the following values: Control (C): 35.78, Control Soft Drinks (CSD): 36.93, Training (T): 39.12, and Training Soft Drinks (TSD): 37.82. The CSD and TSD groups demonstrated the greatest increase in body mass in relation to the C and T groups. In addition, the groups that performed the concurrent training presented a higher mean of the smallest fiber diameter. It was concluded that the ingestion of soft drinks had a negative effect on the muscular hypertrophy of animals submitted to a concurrent training protocol.

El consumo de alimentos y bebidas industrializadas contribuyen al aumento de peso corporal y manifestación de diversas enfermedades. Entre estos alimentos, se encuentran las bebidas refrescantes, que al ser consumidas en grandes proporciones, pueden contribuir al aumento de peso y a la aparición de enfermedades crónicas, tales como la hipertensión, diabetes y obesidad. En cuanto al desempeño, diversos protocolos han sido utilizados, entre estos, el entrenamiento concurrente que puede ser una forma de ayuda en el control de peso corporal y el desarrollo muscular. Siendo así, la identificación de los factores alimentarios, como también la utilización de los métodos correctos de entrenamiento, pueden ser esenciales en el aumento del desempeño físico. El objetivo del estudio fue investigar los efectos del entrenamiento concurrente en la musculatura esquelética de animales sometidos al consumo de bebidas refrescantes. En la presente investigación fueran utilizadas 32 ratas Wistar. Los animales fueran sometidos a un protocolo de entrenamiento concurrente. Después de 48 horas de la última sesión de entrenamiento, los animales fueran sometidos a un proceso quirúrgico para la remoción de muestras de tejido muscular. Los valores de la media del diámetro de las fibras musculares fueron: Control (C): 35,78; Control y Bebida Refrescante (CBR): 36,93; Entrenamiento (ET): 39,12; y Entrenamiento y Bebida Refrescante (EBR): 37,82. Se observó que los grupos CBR y EBR presentaron mayor aumento de masa corporal en comparación con C y T. Además, los grupos que realizaran el entrenamiento concurrente obtuvieron una mayor media en el diámetro de las fibras. Es posible concluir que el consumo de bebidas refrescantes tiene una influencia negativa en la hipertrofia muscular de animales sometidos a un protocolo de entrenamiento concurrente.

Food and beverage industries' participation in health scientific events: considerations on conflicts of interest / Participación de las industrias de la alimentación y las bebidas en acontecimientos científicos sobre temas de salud: consideraciones sobre conflictos de intereses

Several sectors of the industry (pharmaceutical, food, and other) often occupy a prominent position in scientific meetings on health. The aim of this article is to discuss the participation of food and beverage industries (Big Food and Big Soda) in events organized by scientific institutions in health and nutrition, highlighting potential conflicts of interest in such partnerships. As an example, the authors report the case of a Brazilian national event organized by a nutrition scientific association in 2011. Focused on the theme "Evidence-based Nutrition," the event's scientific program was largely influenced by corporate sponsors. For example, a symposium at this congress was organized by a beverage company known worldwide for its sugar-sweetened products and classified as the "diamond sponsor" of the event. While debating the adoption of healthy lifestyles in the current scenario of rising occurrence of obesity, the rationale for health promotion was reduced to providing information that would motivate rational individual choices, thus ignoring any political, economic, cultural, marketing, and social factors involved in the global process of nutrition transition. The authors conclude that conflicts of interest are present in the participation of food and beverage industries in health scientific events. The industries' strategy attempts to grant legitimacy to the production and marketing of their products through an association with adequate health practices. Health professionals and policy-makers should reflect on such partnerships because their main purpose is to generate profit, not the promotion of public health.

Diversos sectores de la industria (farmacéutico, alimentario y otros) a menudo ocupan una posición prominente en las reuniones científicas sobre temas de salud. El objetivo de este artículo es tratar sobre la participación de las industrias de la alimentación y las bebidas (Big Food and Big Soda) en acontecimientos organizados por instituciones científicas del ámbito de la salud y la nutrición, señalando los potenciales conflictos de intereses que surgen de tales asociaciones. Como ejemplo, los autores comentan sobre el acontecimiento nacional organizado el año 2011 en el Brasil por una asociación científica del ámbito de la nutrición. El programa científico de este acontecimiento, dedicado al tema de "La nutrición basada en datos probatorios", se vio influido en gran parte por sus patrocinadores corporativos. Por ejemplo, un simposio de este congreso fue organizado por una empresa productora de bebidas, conocida a escala mundial por sus productos azucarados y clasificada como "patrocinador diamante" del acontecimiento. Mientras se debatía sobre la adopción de modos de vida saludables en el contexto actual de incremento de los casos de obesidad, el ámbito de promoción de la salud se redujo a suministrar información que incitara a elecciones individuales racionales, sin que se tuvieran en cuenta los factores políticos, económicos, culturales, mercadotécnicos y sociales que el proceso mundial de transición nutricional involucra. Los autores concluyen que los conflictos de intereses existen en la participación de las industrias de la alimentación y las bebidas en acontecimientos científicos sobre temas de salud. La estrategia de las industrias intenta dar legitimidad a la producción y comercialización de sus productos mediante una asociación con prácticas de salud adecuadas. Los profesionales de la salud y las instancias normativas deben reflexionar sobre tales asociaciones, ya que su principal finalidad no es la promoción de la salud pública sino la generación de beneficios.

Risk Assessments of Cyclamate, Saccharin, Neohesperidine DC, Steviol Glycosides and Neotamefrom Soft Drinks, “Saft” and Nectar.

The Norwegian Scientific Committee for Food Safety (Vitenskapskomiteen for mattrygghet, VKM), Panel on Food Additives, Flavourings, Processing Aids, Materials in Contact with Food and Cosmetics, has at the request of the Norwegian Food Safety Authority (Mattilsynet) conducted a risk assessment of the intense sweeteners cyclamate, saccharin, neohesperidine DC, steviol glycosides and neotame in soft drinks, “saft” and nectar. The risk assessment includes exposure assessments and the calculated exposures are compared to the acceptable daily intake (ADI) for the respective sweeteners. VKM was also requested to compare the current calculated intake of saccharin and cyclamate to the calculated intake reported by VKM in 2007 (the VKM report «Impact on health when sugar is replaced with intense sweeteners in soft drinks, “saft” and nectar») when possible (VKM, 2007). Six different intake scenarios with varying concentrations of added sweeteners (either the average concentration or the highest reported concentration for the respective sweetener) and varying consumption of beverages with sweeteners (either the actual reported consumption of beverages added sweetener or the assumption that all reported beverages were added sweeteners) were used for the exposure calculations. • Scenario 1 gives the best estimate of the current situation in the population (average content of sweeteners, actual reported consumption). • Scenario 2 is based on the average content of sweeteners and that all consumed beverages contain sweeteners. • Scenario 3 is based on the highest reported content of sweeteners and the actual reported consumption. • Scenario 4 is based on the highest reported content of sweeteners and that all consumed beverages contain sweeteners. Scenarios 5 and 6 are based on the maximum allowed amounts of sweeteners within a category in accordance with the Regulation on food additives, within the categories soft drinks, “saft” and nectar in Norway (Regulation No 668 of 6 June 2011 on food additives, 2011). • In scenario 5 the consumption of beverages with added sweeteners or sugar reported in dietary surveys were used for the calculations. • In scenario 6 it was assumed that all consumed soft drinks, “saft” and nectar contained sweeteners (no sugar). In the current risk assessment, the intake of the sweeteners was calculated for 2-year-old children and 18-70 year old men and women. Due to lack of new dietary surveys, the other age groups of children and adolescents were not included. For all age groups in all scenarios, the intake of the sweeteners cyclamate, saccharin, neohesperidine DC, steviol glycosides and neotame was below their respective established ADI values. Due to possible differences in the calculation, it was not possible to compare the current calculated intake of saccharin and cyclamate to the calculated intake reported by VKM in 2007. VKM concludes that there is no major health concern related to the intake of the sweeteners cyclamate, saccharin, neohesperidine DC, steviol glycosides and neotame from the beverage categories included in this risk assessment per today. VKM further concludes that among young women who are high consumers of beverages with cyclamate, and 2-year-old children who are high consumers of beverages with steviol glycosides, the estimated intake approaches the ADI values. The high intakes approaching ADI are considered conservative estimates, as the highest reported content of sweetener or the maximum allowed amounts is used. Thus, these estimates are only relevant for the part of the population that are both loyal to beverages with sweeteners and a particular brand of sweetened beverage. It should be noted that intake of sweeteners from other foods or from tabletop sweeteners is not included in the intake estimates, and that a considerable contribution from these sources cannot be excluded.

Evaluation of the Prevalence and Correlated Factors for Decreased Bone Mass Density among Pre- and Post-menopausal Educated Working Women in Saudi Arabia.

Most of the previous studies on osteoporosis have focused on post-menopausal women, and more research is needed to evaluate its prevalence in pre-menopausal women. This study was carried out to evaluate the prevalence and correlated factors for decreased bone mass density among pre- and post-menopausal women. This was a cross-sectional study carried out in Applied Medical Sciences College under King Saud University. All pre- and post-menopausal women working there were invited to participate in the study. Measurement of bone mass density was done by quantitative ultrasound densitometry. One-fourth of the pre-menopausal females had osteopaenia. There was a significant correlation between having osteoporosis and increasing age, fertility period, parity, menopausal duration, gynaecological age, and presence of comorbidity, especially hypertension and diabetes mellitus. Pre-menopausal females had high prevalence of osteopaenia (24.8%), and it is recommended to implement health education campaigns demonstrating the preventive measures of osteoporosis.

Overweight in Brazilian industry workers: Prevalence and association with demographic and socioeconomic factors and soft drink intake / Excesso de peso em trabalhadores de indústrias no Brasil: prevalência e associação com fatores demográficos, socioeconômicos e consumo de refrigerantes

Objective: To estimate the prevalence of overweight in industry workers and its association with demographic and socioeconomic factors and soft drink intake (including type). Methods: This is a nationwide cross-sectional cohort survey of "Lifestyle and leisure habits of industry workers" conducted between 2006 and 2008 in 24 Brazilian federate units. The participants answered a previously tested questionnaire and self-reported their weight and height. Statistical analyses consisted of crude and adjusted Poisson regression. Results: Males and females had overweight prevalences of 45.7% (95%CI=45.1; 46.2) and 28.1% (95%CI=27.4; 28.9) respectively. Older and married individuals and those working in medium-sized and large factories were more likely to be overweight. Males with higher education levels and gross family incomes were also more likely to be overweight, but not females. Finally, men (PR=1.24; 95%CI=1.13; 1.36) and women (PR=1.40; 95%CI=1.22; 1.61) who consumed diet/light soft drinks were also more likely to be overweight than those who did not consume soft drinks. Conclusion: More than one-third of the workers were overweight according to their self-reported weight and height, and the prevalence of overweight was higher in males. Demographic and socioeconomic variables and diet/light soft drink intake were associated with overweight. These data may be helpful for the development of actions that reduce the risk of overweight in this population. .

Objetivo: Estimar a prevalência de excesso de peso e sua associação com fatores demográficos, socioeconômicos e com o consumo e tipo de refrigerante ingerido. Métodos: Trata-se de um inquérito nacional, de corte transversal, sobre o "Estilo de vida e hábitos de lazer de trabalhadores da indústria", realizado nos anos de 2006 a 2008, em 24 unidades federativas do Brasil. As informações foram obtidas por meio de um questionário previamente testado, inclusive a informação sobre o excesso de peso (autorrelato do peso e da estatura). Regressões de Poisson bruta e ajustada foram realizadas. Resultados: A prevalência de excesso de peso foi de 45,7% (IC95%=45,1; 46,2) nos homens e 28,1% (IC95%=27,4; 28,9) nas mulheres. Identificou-se que o aumento da idade, ser casado e o tamanho das empresas (médio e grande porte) associaram-se a maiores probabilidades para o excesso de peso. Quanto maior a escolaridade e a renda familiar bruta entre os homens, maior a probabilidade de excesso de peso, tendo sido observada situação contrária entre as mulheres. Homens (RP=1,24; IC95%=1,13; 1,36) e mulheres (RP=1,40; IC95%; 1,22; 1,61) que relataram consumir refrigerantes diet/light também apresentaram maior excesso de peso quando comparados àqueles que relataram não consumir refrigerantes. Conclusões: Em seus autorrelatos, mais de um terço dos trabalhadores foram classificados com excesso de peso, com maior prevalência entre os homens. Variáveis demográficas, socioeconômicas e consumo de refrigerantes diet/light se mostraram associados ao excesso de peso. Tais informações podem auxiliar na elaboração de ações direcionadas para redução da probabilidade do excesso de peso nesse grupo. .

Consumo de refrigerantes e estado nutricional de adolescentes de uma escola do município de São Paulo / Consumption of soft drinks and nutritional status of adolescents from a public school in São Paulo

The objective of this study was to evaluate the association between daily soft drink consumption and the nutritional status of adolescents at a Technical School in the metropolitan region of the city of São Paulo. Data were obtained from a cross-sectional study with 106 high school students. The intake of soft drinks was assessed by a food frequency questionnaire and the body mass index (BMI) was calculated. Data were analyzed using the SPSS 13.0 software. The Chi-square test was applied to verify possible association between daily soft drink consumption and nutritional status. We found that the most prevalent frequency of soft drink consumption was 2-4 times a week. The average daily consumption was more prevalent among boys (320 mL) than girls (170 mL) (p=0.05). When the BMI was assessed, it was possible to verify that most teenagers presented adequate weigh, 13.5% of the individuals were overweight, and 9.6% were obese. Through the analysis of the nutritional status and soda consumption, we observed that overweight adolescents consumed more soft drinks than the obese ones, and these showed greater consumption of diet and light soft drinks, revealing a possible concern with weight. However, there was no association between soft drink consumption and nutritional status (p=0.81). The consumption of soft drinks was high among adolescents, being higher among boys and overweight individuals.

El objetivo de este estudio fue evaluar la asociación entre el consumo diario de bebidas gaseosas y el estado nutricional de los adolescentes de una escuela técnica de la ciudad de San Pablo, Brasil. Los datos fueron obtenidos de un estudio transversal de 106 adolescentes estudiantes de secundaria de una escuela técnica en la región metropolitana. Se evaluó el consumo de bebidas gaseosas a través de un cuestionario de frecuencia alimentaria y se calculó el índice de masa corporal (IMC). Los datos fueron analizados utilizando el programa SPSS 13.0. Se aplicó la prueba de chi-cuadrado para detectar una posible asociación entre el consumo de refrescos y el estado nutricional. En la muestra, caracterizada por una distribución uniforme de géneros, se encontró que la frecuencia más prevalente de consumo de bebidas gaseosas fue de 2 a 4 veces por semana. El consumo diario promedio entre los varones fue de 320 mL y entre las niñas de 170 mL (p=0,05). Cuando se analizó el IMC, se encontró que la mayoría de los adolescentes fueron eutróficos, 13,5% tuvieron sobrepeso y 9,6% eran obesos. Cuando se analizó el estado nutricional y el consumo de gaseosas, se observó que los adolescentes con sobrepeso consumían más bebidas gaseosas que los obesos y éstos consumían más refrescos dietéticos, revelando una posible preocupación con su peso. Sin embargo, no hubo asociación entre el consumo de refrescos y el estado nutricional (p=0,81). El consumo de bebidas gaseosas fue alto entre los adolescentes, siendo mayor entre los niños y los que tienen sobrepeso.

O consumo de refrigerante mostrou-se elevado entre os adolescentes, sendo maior entre os meninos e aqueles com excesso de peso.

Conocimiento sobre el consumo de agua simple en adultos de nivel socioeconómico bajo de la ciudad de Cuernavaca, México / Knowledge about consumption of plain water in adults of low socioeconomic status of the city of Cuernavaca, México

Objetivo. Describir los conocimientos cotidianos acerca del consumo de agua simple en adultos "pequeños bebedores" y "grandes bebedores" de agua simple. Material y métodos. Estudio cualitativo realizado entre abril y agosto de 2010 en México. Se conformaron ocho grupos focales con informantes clave adultos de nivel socioeconómico bajo; la mitad de los grupos se conformaron con hombres y la mitad con mujeres. El análisis de datos fue realizado mediante: a) codificación y categorización de acuerdo con literatura revisada acerca de hidratación, y b) mapeo conceptual, reconociendo proposiciones y afirmaciones hechas por los participantes. Resultados. Pequeños y grandes bebedores tienen conocimientos cotidianos similares sobre el agua simple; utilizan los mismos ejes epistemológicos para explicar la ingesta de agua simple en función de lo que "el cuerpo necesite". Ambos grupos tienen la noción de que el agua simple y el refresco "pueden ser dañinos" si se beben en exceso. Conclusiones. El conocimiento cotidiano sobre el agua se relaciona con el refresco, bebida que sirve para comparación y como sustituto. Los conceptos sobre el agua y el refresco se construyen con base en la experiencia personal y en las nociones sobre el efecto de ambos en el cuerpo y en la mente. Estas representaciones se utilizan para valorar la ingesta de líquidos y pueden constituirse como barreras para el consumo de agua simple.

Objective. To describe and compare the everyday knowledge about plain water consumption among "small" and "big drinkers". Materials and methods. A qualitative study was conducted between April and August 2010 in Mexico. Eight focus groups with low socioeconomic status adults as key informants were conformed; half of the groups were conducted with men and half with women. Data analysis was conducted with: a) coding and categorization according to hydration literature review b) conceptual mapping, recognizing propositions and affirmations made by the participants. Results. Small and big drinkers have similar everyday knowledge about plain water intake. Both groups use the same epistemological axes to explain its intake: "what the body needs". Both groups have the notion that plain water and other beverages such as soda "may be harmful" if you drink them in excess. Conclusions. Everyday knowledge about water is related to soda and drinks used to substitute water intake. The characteristics of water and soda intake are constructed based on personal experience and insights on their effect on the body and mind. These representations can be used to assess fluid intake and may constitute barriers to the consumption of plain water.

Added sugars: consumption and associated factors among adults and the elderly. São Paulo, Brazil / Açúcares de adição: consumo e fatores associados entre adultos e idosos. São Paulo, Brasil

OBJECTIVE: To investigate added sugar intake, main dietary sources and factors associated with excessive intake of added sugar. METHODS: A population-based household survey was carried out in São Paulo, the largest city in Brazil. Cluster sampling was performed and the study sample comprised 689 adults and 622 elderly individuals. Dietary intake was estimated based on a 24-hour food recall. Usual nutrient intake was estimated by correcting for the within-person variance of intake using the Iowa State University (ISU) method. Linear regression analysis was conducted to identify factors associated with added sugar intake. RESULTS: Average of energy intake (EI) from added sugars was 9.1% (95% CI: 8.9%; 9.4%) among adults and 8.4% (95% CI: 8.2%; 8.7%) among the elderly (p < 0.05). Average added sugar intake (% EI) was higher among women than among men (p < 0.05). Soft drink was the main source of added sugar among adults, while table sugar was the main source of added sugar among the elderly. Added sugar intake increased with age among adults. Moreover, higher socioeconomic level was associated with added sugar intake in the same group. CONCLUSIONS: Added sugar intake is higher among younger adults of higher socioeconomic level. Soft drink and table sugar accounted for more than 50% of the sugar consumed.

OBJETIVO: Avaliar o consumo alimentar, principais fontes dietéticas e fatores associados à ingestão acima da recomendação de açúcares de adição. MÉTODOS: Um inquérito populacional domiciliar foi realizado em São Paulo, a maior cidade do Brasil. A população de estudo foi obtida por um processo de amostragem por conglomerados e composta por 689 adultos e 622 idosos. O consumo alimentar foi estimado por um recordatório de 24 horas. Os valores nutricionais foram ajustados pela variância intra pessoal, utilizando o método instituído pela Universidade de Iowa (ISU). A regressão linear foi conduzida para identificar os fatores associados ao consumo de açúcares de adição s. RESULTADOS: A média de energia proveniente dos açúcares de adição foi de 9,1% (IC 95%: 8,9%; 9,4%) entre adultos e 8,4% (IC 95%: 8,2%; 8,7%) entre idosos (p < 0,05). A média do consumo de açúcares de adição foi maior entre mulheres quando comparada à dos homens (p < 0,05). A principal fonte de açúcares de adição foi refrigerante entre adultos, enquanto que entre idosos foi açúcar de mesa. O consumo de açúcares de adição aumentou conforme a idade entre adultos. Além disso, o alto nível socioeconomico esteve associado com o consumo de açúcares de adição entre adultos. CONCLUSÕES: O consumo de açúcares de adição é maior entre adultos de nível socioeconômico alto. Refrigerantes e açúcares de mesa são responsáveis por mais de 50% do consumo de açúcares.

Iron supplementation reduces the erosive potential of a cola drink on enamel and dentin in situ

Iron has been suggested to reduce the erosive potential of cola drinks in vitro.OBJECTIVE: The aim of this study was to evaluate in situ the effect of ferrous sulfate supplementation on the inhibition of the erosion caused by a cola drink. MATERIAL AND METHODS: Ten adult volunteers participated in a crossover protocol conducted in two phases of 5 days, separated by a washout period of 7 days. In each phase, they wore palatal devices containing two human enamel and two human dentin blocks. The volunteers immersed the devices for 5 min in 150 mL of cola drink (Coca-ColaTM, pH 2.6), containing ferrous sulfate (10 mmol/L) or not (control), 4 times per day. The effect of ferrous sulfate on the inhibition of erosion was evaluated by profilometry (wear). Data were analyzed by paired t tests (p<0.05). RESULTS: The mean wear (±se) was significantly reduced in the presence of ferrous sulfate, both for enamel (control: 5.8±1.0 µm; ferrous sulfate: 2.8±0.6 µm) and dentin (control: 4.8±0.8 µm; ferrous sulfate: 1.7±0.7 µm). CONCLUSIONS: The supplementation of cola drinks with ferrous sulfate can be a good alternative for the reduction of their erosive potential. Additional studies should be done to test if lower ferrous sulfate concentrations can also have a protective effect as well as the combination of ferrous sulfate with other ions.

Soft drinks: Are they really soft.

We report a case of epileptic seizures following heavy consumption of a cola and caffeine containing soft drink. The probable cause for seizures could be due to a combination of hyponatraemia, water intoxication, and high dose of caffeine and aspartame from the soft drink.

A Study on the Status of Beverage Consumption of the Middle School Students in Jeonju / 대한지역사회영양학회지

To investigate how the beverage consumption of middle school students are different in some respects; favorite kinds, drinking time and so on. 579 middle school students in Jeonju were participated in this study. This study shows the frequency of drinking beverage and the correlation between the frequency and the various factors to have effects on the frequency. The students usually drink water 8.55 times, milk or yogurt 3.01 times, sport beverage 2.13 times, soft drink 1.93 times, and fruit and vegetable juice 1.85 times for one week. The boy students prefer more soft or sport drink to the girl students. However the drinking of other beverages such as water, milk, juice, traditional ones don't have any meaningful differences between the boys and the girls. The students drink water mostly when they have meals. And the second consuming beverage is milk at table. It explains the students who drink more milk than water with bread. There is a big difference according to their excercise frequency. The students who excercise regularly or excercise over 3 hours drink more soft or sport drink and milk or yogurt than the students who exercise less than 1 hour. The beverages are firstly needed during the exercise because they sweat. And the second beverage time is when they have snacks and when they take a break. It should be suggested that nutrition education targeted to middle school students and their parents should encourage limited consumption of soft drinks. Therefore, policies that limit students' access to soft drinks at schools should be promoted.
