Efficacy of L-Arabinose in Lowering Glycemic and Insulinemic Responses: The Modifying Effect of Starch and Fat

L-arabinose is a bio-active compound derived from the side-streams of plant food processing. L-arabinose lowers glycemic and insulinemic responses when added to simple water-based sugary liquids. However, the effect in more complex foods, including fat and starch, is inconsistent. This study assessed the effect of fat or starch in a sugary drink on the efficacy of L-arabinose. Twenty-three healthy volunteers (12 female/11 male; aged 24 ± 3 years; BMI 23 ± 3 kg/m2) participated in a randomised cross-over trial with six drinks: control: 50 g sucrose in water; fat: control + 22 g oil; starch: control + 50 g starch; and all three with and without the addition of 5 g L-arabinose. The addition of L-arabinose to the control drink lowered glucose and insulin peaks by 15% and 52%; for the fat drink by 8% and 45%; and for the starch drink by 7% and 29%. For all three drinks, adding L-arabinose increased glucagon-like peptide 1 (GLP-1) responses and lowered Glucose-dependent insulinotropic polypeptide (GIP) responses. Despite adding large quantities of starch and fat to sugary drinks, L-arabinose significantly lowered postprandial glycemic and insulinemic responses in healthy subjects. These findings suggest that L-arabinose can be functional in more complex foods; however, the factors affecting its efficacy in solid food matrices need to be studied in more detail.

Electoral campaign contributions: an obstacle to health-related sugary drinks regulation in Brazil? The case of the Chamber of Deputies

Objective: To assess corporate electoral campaign contributions from industries related to sugary drinks production and the characteristics of the elected officials financed by the sector. Design: Cross-sectional analysis of electoral campaign contributions from corporations related to sugary drinks production (sugary drink industries and sugary drink input industries) to candidates to the Chamber of Deputies, Brazil. Setting: Elections to the 55th Congress (2015-2019), held in October 2014. Participants: Candidates to the Chamber of Deputies, Brazil. Results: Forty-nine companies or corporate groups that produce sugary drinks and 52 corporations that produce inputs for sugary drinks manufacturing contributed to electoral campaigns of candidates in the 2014 Election. Contributions from this industry sector represented 7.3% of all corporate contributions and helped finance 11.7% of the candidates and 46.2% of the elected officials. The transnationals Ambev and Coca-Cola were the first and second biggest donors, respectively. Revenues mediated by political parties, from sugary drink industries, and from corporate members of some industry associations (Abir, Unica and CitrusBR) were more prevalent. Among elected officials, a significant association was found between being financed by the sector and representing the Southeast region, having higher education level and referring themselves as being professional politicians. In the multivariate model, financed candidates were 27% more likely to be elected. Conclusions: Corporations related to sugary drinks production have contributed to the electoral campaigns of almost half of the Federal Deputies in Brazil in 2014. This possibly facilitates access to decision-makers and could help buy influence on legislative proposals, including health-related food policies.

Public Acceptability of Policy Interventions to Reduce Sugary Drink Consumption in Urban Vietnam

This study aims to assess the public acceptability of interventions to reduce sugary drinks in Vietnam, identify the key determinants, and develop a classification of consumers. A cross-sectional survey with 263 urban consumers evaluated perceptions of four potential interventions: restricting choice, taxation, nudging, and labeling. Thereby, specific attention was devoted to perceived intrusiveness and (personal and societal) effectiveness, as well personal characteristics, including Confucius values. Results showed that “hard” interventions like taxation are less acceptable to consumers than “soft” measures such as labeling. Acceptability is generally affected by perceived intrusiveness and effectiveness (especially on other people in the society), while other factors (sugary drink behavior, trust in government’s competence, personal values, age, education) only matter for some of the interventions. Cluster analysis revealed three consumer segments, depicted as anti-taxation (28%), pro-intervention (20%) and pro-labeling (52%), which further underpins the heterogeneity of intervention acceptability.

Associations between State-Level Obesity Rates, Engagement with Food Brands on Social Media, and Hashtag Usage

Food advertisement exposure is associated with increased caloric intake, but little is known about food/beverage placements in the digital media environment. We aimed to examine the correlation between the number of people who follow food and beverage brand social media accounts (i.e., user engagement) and state-level obesity rates; quantify social media followers’ use of “healthy” vs. “unhealthy” hashtags; and analyze the relationship between user engagement and hashtag usage. We identified the 26 fast-food and beverage brands with the highest advertising expenditures and used Demographics Pro to determine the characteristics of social media users amongst the 26 brands. A series of regression analyses were conducted that related the mean percentage of brand followers and state-level obesity rates. We then identified 733 hashtags on Instagram and 703 hashtags on Twitter, coding them as “healthy”, “unhealthy”, “neutral”, or “unrelated to health”. Intercoder reliability was established using ReCal2, which indicated a 90% agreement between coders. Finally, we conducted ANCOVA to examine the relationship between the mean percentage of brand followers and their hashtag usage. There was a significant, positive correlation between the state-level obesity rate and the mean percentage of followers of sugary drink or fast-food brands on Instagram and Twitter, but such a correlation between obesity and low-calorie drink brand followers was only found on Twitter. Our findings illustrate the relationship between the social media food environment and obesity rates in the United States. Given the high rates of engagement with food brands on social media, policies should limit digital advertisements featuring fast-food, sugary drink, and low-calorie drink brands.

Sugary drink consumption and risk of kidney and bladder cancer in Japanese adults

Globally, sugary drinks are widely consumed, however, few epidemiologic studies have investigated the association between sugary drink consumption and risk of kidney and bladder cancer. We examined the association of sugary drinks with risk of kidney and bladder cancer in 73,024 participants from the Japan Public Health Center-based Prospective Study who reported no history of cancer. Sugary drink consumption was assessed using a validated food frequency questionnaire at study baseline (1995–1999). Individuals were followed to December 31, 2013. Multivariable Cox proportional hazards regression models were used to calculate hazard ratios (HR) and 95% confidence intervals (CIs). During 1,069,815 person years of follow-up, 169 kidney cancer and 297 bladder cancer cases were documented. After adjusting for potential confounders, no greater risk of kidney and bladder cancer was observed. However, sugary drink consumption was positively associated with the risk of kidney cancer (HR for 100 ml/day increase in consumption was 1.11 [95% CI 1.01–1.22]) and bladder cancer (HR for 100 ml/d increase in consumption was 1.11 [95% CI 1.01–1.22]) among women after exclusion of cases diagnosed in the first three years of follow-up. In this large prospective cohort, consumption of sugary drinks was significantly associated with a small increase in hazard ratio for kidney and bladder cancer among women after exclusion of cases diagnosed within the first three years.

A Salient Sugar Tax Decreases Sugary-Drink Buying

Many governments have introduced sugary-drink excise taxes to reduce purchasing and consumption of such drinks; however, they do not typically stipulate how such taxes should be communicated at the point of purchase. Historical, field, and experimental data consisting of more than 225,000 purchase decisions indicated that introducing a $0.01-per-ounce sugar-sweetened beverage (SSB) tax—without making it salient on price tags—had no significant effect on purchasing (−1.26%, p = .28). However, when the phrase “includes sugary drink tax” was added to tax-inclusive price tags, SSB purchasing was lower than (a) in the pretax period (−9.78%, p < .001), (b) in a posttax period when drinks did not bear price tags (−5.04%, p < .001), and (c) in a posttax period when drinks bore tax-inclusive price tags that did not mention the tax (−3.83%, p = .002). Making the tax’s beneficiary (student programs) salient on price tags had no added effect. Two follow-up studies suggested that tax salience was effective partly because consumers overestimated the tax amount, leading to reduced purchase intentions.

Race, Ethnicity, and Neighborhood Food Environment Are Associated with Adolescent Sugary Drink Consumption During a 5-Year Community Campaign

Background A multi-level county-wide campaign to reduce sugary drink consumption was associated with significant decreases in retail sales of soda and fruit drinks. The aim of the current study was to examine changes in adolescent beverage consumption during the campaign by race/ethnicity and neighborhood food environment. Methods Beverage consumption among adolescents was evaluated at four time points in a repeated cross-sectional survey of a racially and ethnically diverse sample of sixth graders (N = 13,129) from public middle schools in the county. Each school’s surrounding attendance zone (i.e., neighborhoods where students live) was characterized as providing high or low exposure to unhealthy food retail (e.g., convenience stores, fast-food restaurants). Logistic and multiple linear regression models were used to evaluate changes in beverage consumption over time by student race/ethnicity and high versus low unhealthy food exposure. Results Over the 5 years, there were significant declines in the overall share of students who reported daily sugary drink consumption (49.4 to 36.9%) and their reported daily calories from these products (220 to 158 calories). However, disparities were observed, with higher levels of consumption among Black and Hispanic youth and among youth living in neighborhoods with more unhealthy food retail. Notably, Black students living in healthier neighborhood food environments reported significant decreases in daily consumption and calories after 5 years, while Black students living in neighborhoods with more convenience stores and fast-food outlets did not. Conclusion These findings suggest that both race/ethnicity and neighborhood food environments are important considerations when designing interventions to reduce sugary drink consumption among adolescents.

Influence of paternal general parenting on Latino early adolescents’ energy balance-related behaviours and interactions with behaviour-specific parenting practices

Objective: To investigate the influence of general parenting dimensions on adolescents’ energy balance-related behaviours (EBRB) and its interactions with behaviour-specific parenting practices based on Darling and Steinberg’s contextual model of parenting style. Design: Multiple linear regression analyses and the Hayes PROCESS procedure to analyse self-reported cross-sectional survey data. Setting: In-person survey. Participants: Latino early adolescents and their fathers (n 225 dyads) recruited using convenience sampling from metropolitan areas of north-central USA. Results: Both paternal parenting dimensions of warmth and autonomy granting were positively associated with adolescents’ fruit intake, vegetable intake and physical activity. Coercive control was positively associated with adolescents’ sugary drink intake and sweets/salty snack intake. These associations were predominantly mediated by the parenting practices of setting expectations/allowances, role modelling, and managing availability and accessibility for corresponding EBRB. After adjusting for parenting practices, paternal warmth was inversely associated with adolescents’ screen time, paternal autonomy was positively associated with sugary drink intake, and both paternal warmth and autonomy granting were positively associated with adolescents’ fast food intake. In addition, positive associations between fathers’ parenting practices and adolescents’ sugary drink intake were significantly stronger among those who perceived high v. low levels of paternal warmth and autonomy granting. Conclusions: Paternal warmth and autonomy granting showed mixed effects on adolescents’ EBRB, and coercive control showed undesirable relationships with adolescents’ dietary intake via interactions with behaviour-specific parenting practices. Lifestyle intervention programmes for Latino adolescents need to consider incorporating paternal parenting education components.

Gamification and Sugar: A School-Based Pilot Study of Social Marketing and Gamification Approaches to Reduce Sugary Drink Intake in Pasifika School Students

The aim of this study was to investigate a social marketing–gamification intervention to reduce sugary drink intake drawing on popular culture of Pasifika secondary school students in Auckland, New Zealand. Students aged 11 to 14 years from one coeducational high school participated in the 11-week pilot study. The 9-week intervention was undertaken in assemblies and classrooms. Baseline and follow-up measures were completed by 227 and 220 students, respectively, of 298 enrolled students. Retention of the “3-6-9” teaching related to maximum daily sugar intake increased from 9% at baseline to 97% at follow-up ( P < .0001). Significant increases were observed of students who correctly answered sugar content of drinks. Overall consumption of sugary drink decreased at follow-up by 0.46 glasses per day. The main conclusion from this study was that this school-based gamification educational package to convey messages about sugar content of drinks using popular modes of engagement is a promising intervention that was acceptable and well supported by school staff and students.
