Patterns and predictors of low-calorie sweetener consumption during pregnancy: findings from a national survey in Australia

Emerging evidence has indicated that perinatal exposure to low-calorie sweeteners (LCSs) might be associated with adverse pregnancy outcomes and offspring health(1). The aim of the study was to examine the patterns and predictors of LCS consumption among pregnant women in Australia. A web-based survey was conducted among 422 pregnant women aged 18-50 years between September and October 2022. Participants were recruited by a reputable consumer panel provider, Qualtrics. Sociodemographic, lifestyle, dietary intake (including LCS consumption), pregnancy-related characteristics, and participants’ awareness regarding the potential health effects of LCS were assessed. We assessed LCS consumption from twelve food groups that are common sources of LCS(2). To identify LCS consumption patterns and predictors of the patterns, a latent class analysis and hierarchical multinomial logistic regression was employed, respectively. The women’s mean (SD) age was 30 (4.6) years. Overall, 95% of the women reported consuming any LCS in the current pregnancy. Three different LCS consumption patterns were identified. Infrequent or non-consumers, representing 50% of the women, included those who rarely or never consumed LCS-containing foods and beverages (with a probability of less than 10%). The second pattern, moderate consumption, which encompassed 40% of the women, indicated low to moderate consumption of LCSs (for instance, the likelihood of consuming LCS-containing drinks ranged from 18% to 50%). The third pattern highlighted habitual consumption. These individuals (10%) had a high likelihood (ranging from 75% to 95%) of consuming foods from all food groups that contained LCS. The majority of women (71%) were unaware of the potential adverse effects of LCS, and only 25% expressed concerns about the potential impacts of LCS on their health and the health of their offspring. Moreover, women who frequently consumed sugar-sweetened beverages (SSBs) (≥2 times/week) or had gestational diabetes were over three times more likely to adopt a habitual LCS consumption pattern compared to those who consumed SSBs less often [adjusted relative risk ratio (aRRR) = 3.17, 95% CI: 1.39-7.21] and those without gestational diabetes [aRRR = 3.53, 95% CI: 1.03-12.10]. Additionally, having a medical condition was linked to a 55% lower chance of moderate LCS consumption compared to infrequent or non-consumption. These findings indicate LCS consumption is widespread, but awareness of its potential adverse health effect is low among pregnant women in Australia. Public health interventions to increase the awareness of potential adverse effect of LCS consumption, particularly among pregnant women with moderate and habitual consumption are warranted.

Abstract MP48: Consumption of Low-Calorie Sweeteners Among Infants, Toddlers, and Preschoolers in the United States, NHANES 2013-2018

Introduction: Research has highlighted the rising consumption of low-calorie sweeteners (LCSs) and their possible negative health implications. While the American Academy of Pediatrics advises against beverages with LCSs for children under 5y, little is known about current consumption patterns among infants and young children in the United States. Objectives: To estimate the prevalence, frequency, and top sources of LCS intake among U.S. infants and young children and to investigate associations between LCS consumption and energy and macronutrient intake. Methods: We used one 24-h dietary recall from 3117 children aged 0-5y in the National Health and Nutrition Examination Survey (NHANES) 2013-18 to describe the prevalence and their frequency of consuming foods and beverages containing LCSs. We also compared total energy and macronutrient intake as a proportion of total energy intake (TEI) between LCS consumers and non-consumers. Complex survey procedures and sample weights were applied for all analyses. F-tests were used to compare consumption estimates across sociodemographic subgroups. Results: Thirty percent of all U.S. children aged 0-5y consumed foods and/or beverages with LCSs, including 17.5% of infants (0-1y), 34.3% of toddlers (2 and 3y), and 34.5% of preschoolers (4 and 5y). Prevalence of LCS consumption tended to be highest among non-Hispanic Blacks children and those from households with higher educational attainment or a higher family income. Among consumers, mean frequency of any LCS product, LCS beverages (LCSBs) only, and LCS foods (LCSFs) only was 1.4, 1.4, and 1.1 times/day, respectively, and did not differ by age. The most consumed of all LCSBs were fruit drinks (71.9%) and the most consumed of all LCSFs was yogurt (not-Greek) (59.5%). Compared to non-consumers, LCS consumers had higher intake of total energy, 1516 vs. 1316 kcal/day (p<.0001), carbohydrates, 54.0% vs 52.4% TEI (p=.0005), and added sugar, 3.3% vs. 2.1% TEI (p<.0001) but significantly lower intake of total fat and saturated fat, 33.1% vs 34.9% TEI (p<.0001) and 12.0% vs 13.1% TEI (p<.0001), respectively. Conclusions: LCS consumption is prevalent among infants and young children in the U.S. and fruit drinks and yogurt are the main sources. These results highlight the need for further research to understand long-term implications of this consumption. Funding sources: None.

The MILK study: Investigating intergenerational transmission of low-calorie sweeteners in breast milk

IntroductionForty-four percent of lactating women in the United States consume beverages containing low calorie sweeteners (LCS), and the presence of LCS in the food supply has continued to increase in recent years. While LCS are approved by the United States Food and Drug Administration (FDA) and are believed to be safe for human consumption, intergenerational LCS transmission and the health impacts of early life LCS exposure are severely understudied. Methods and analysisIn a tightly controlled, single site, prospective interventional study, mothers' plasma and breast milk, and infants’ plasma will be collected from 40 mother-infant dyads over the course of 72 h, with rich sampling following maternal ingestion of a LCS sweetened beverage containing sucralose and acesulfame potassium (ace-K). Concentration-time data will be used to build maternal and infant pharmacokinetic models for future simulations and analysis. ConclusionThis study aims to measure LCS concentrations in breast milk, maternal plasma, and infant plasma, to gain insight into infant exposure and inform recommendations for LCS consumption during breastfeeding.

Patterns and Predictors of Low-Calorie Sweetener Consumption during Pregnancy: Findings from a National Survey.

Recently, the World Health Organization recommended avoiding low-calorie sweeteners (LCS) during pregnancy due to concerns that it may be linked to adverse pregnancy outcomes and offspring wellbeing. This study examined the patterns and predictors of LCS consumption among pregnant women in Australia. A survey was conducted among 422 pregnant women aged 18-50 years. Sociodemographic, lifestyle, dietary intake including LCS consumption, pregnancy-related characteristics, and awareness about the health effects of LCS were assessed. We used latent class analysis and multinomial logistic regression to identify LCS consumption patterns and predictors of consumption patterns, respectively. The mean (SD) age of the women was 30 (4.6) years. Three LCS consumption patterns were identified: infrequent or non-consumers representing 50% of the women, moderate consumers encompassing 40% of the women, and the remaining were habitual consumers. Over two-thirds (71%) of women were not aware of the potential adverse effects of LCS, and only a quarter of them were concerned about the possible adverse effects on their health and their offspring. Increasing age and living with a medical condition decreased the likelihood of moderate consumption by 7% and 55%, respectively. Frequent sugar-sweetened beverage consumption and gestational diabetes predicted habitual LCS consumption. This research suggested widespread LCS consumption among pregnant women in Australia, but lower awareness of its potential adverse health effects. Interventions to increase awareness of potential adverse effects are warranted.

1160-P: Low-Calorie Sweeteners and Quality of Life in Youth with Type 1 Diabetes

Background: Low calorie sweeteners (LCSs) are often used by youth with Type 1 Diabetes (T1D), as LCS can provide added sweetness to food and beverages at a reduced glycemic load. Whether LCS consumption is helpful or harmful for T1D management among youth is debated; however, little attention has been given to potential benefits of LCS consumption on psychosocial outcomes among youth with T1D. This is important because a diabetes diagnosis pervades all aspects of a child's life and LCS use may provide children with T1D with a sense of normalcy, potentially increasing their health-related quality of life (HRQOL). Objective: To examine associations between LCS consumption and HRQOL among youth with T1D. Methods: Sixty youth ages 11-17 with a diagnosis of T1D (Mage 12.9±1.8, 57.1% female, 70% Non-Hispanic White) and their parents (83.3% female, 71.6% Non-Hispanic White) were recruited from the Washington Nationals Diabetes Care Complex at Children's National Hospital (DCC) in Washington D.C. (N=20) and nationally using social media (N=40). Eligible youth and their parent attended a virtual study visit, where they provided demographic information, and completed a LCS consumption questionnaire (developed by the team for a previous study), along with the validated Type 1 Diabetes and Life measure (T1DAL). Means and frequencies were used to summarize the survey data, as appropriate, and associations between LCS intake and HRQOL were examined using multivariable linear regression, with adjustment for relevant covariates. Results: Mean LCS consumption was 3.3±2.8 servings per day. No associations between LCS consumption (total, LCS beverage consumption, LCS food consumption) and HRQOL (total and subscales) were observed. Conclusion: In our sample of youth with T1D, LCS intake was not associated with HRQOL. These results demonstrate that LCS use may not benefit psychosocial outcomes of youth with T1D, further reiterating the need to determine their metabolic and health effects in this high-risk patient population.

Maternal low-calorie sweetener consumption rewires hypothalamic melanocortin circuits via a gut microbial co-metabolite pathway.

The prevalence of obesity and type 2 diabetes is growing at an alarming rate, including among pregnant women. Low-calorie sweeteners (LCSs) have increasingly been used as an alternative to sugar to deliver a sweet taste without the excessive caloric load. However, there is little evidence regarding their biological effects, particularly during development. Here, we used a mouse model of maternal LCS consumption to explore the impact of perinatal LCS exposure on the development of neural systems involved in metabolic regulation. We report that adult male, but not female, offspring from both aspartame- and rebaudioside A-exposed dams displayed increased adiposity and developed glucose intolerance. Moreover, maternal LCS consumption reorganized hypothalamic melanocortin circuits and disrupted parasympathetic innervation of pancreatic islets in male offspring. We then identified phenylacetylglycine (PAG) as a unique metabolite that was upregulated in the milk of LCS-fed dams and the serum of their pups. Furthermore, maternal PAG treatment recapitulated some of the key metabolic and neurodevelopmental abnormalities associated with maternal LCS consumption. Together, our data indicate that maternal LCS consumption has enduring consequences on the offspring's metabolism and neural development and that these effects are likely to be mediated through the gut microbial co-metabolite PAG.

Early-life influences of low-calorie sweetener consumption on sugar taste

Children and adolescents are the highest consumers of added sugars, particularly from sugar-sweetened beverages (SSB). Regular consumption of SSB early in life induces a variety of negative consequences on health that can last into adulthood. Low-calorie sweeteners (LCS) are increasingly used as an alternative to added sugars because they provide a sweet sensation without adding calories to the diet. However, the long-term effects of early-life consumption of LCS are not well understood. Considering LCS engage at least one of the same taste receptors as sugars and potentially modulate cellular mechanisms of glucose transport and metabolism, it is especially important to understand how early-life LCS consumption impacts intake of and regulatory responses to caloric sugars. In our recent study, we found that habitual intake of LCS during the juvenile-adolescence period significantly changed how rats responded to sugar later in life. Here, we review evidence that LCS and sugars are sensed via common and distinct gustatory pathways, and then discuss the implications this has for shaping sugar-associated appetitive, consummatory, and physiological responses. Ultimately, the review highlights the diverse gaps in knowledge that will be necessary to fill to understand the consequences of regular LCS consumption during important phases of development.

Early Life Low-Calorie Sweetener Consumption Impacts Energy Balance during Adulthood.

Children frequently consume beverages that are either sweetened with sugars (sugar-sweetened beverages; SSB) or low-calorie sweeteners (LCS). Here, we evaluated the effects of habitual early life consumption of either SSB or LCS on energy balance later during adulthood. Male and female rats were provided with chow, water, and a solution containing either SSB (sucrose), LCS (acesulfame potassium (ACE-K) or stevia), or control (no solution) during the juvenile and adolescent periods (postnatal days 26-70). SSB or LCS consumption was voluntary and restricted within the recommended federal daily limits. When subsequently maintained on a cafeteria-style junk food diet (CAF; various high-fat, high-sugar foods) during adulthood, ACE-K-exposed rats demonstrated reduced caloric consumption vs. the controls, which contributed to lower body weights in female, but not male, ACE-K rats. These discrepant intakes and body weight effects in male ACE-K rats are likely to be based on reduced gene expression of thermogenic indicators (UCP1, BMP8B) in brown adipose tissue. Female stevia-exposed rats did not differ from the controls in terms of caloric intake or body weight, yet they consumed more SSB during CAF exposure in adulthood. None of the SSB-exposed rats, neither male nor female, differed from the controls in terms of total adult caloric consumption or body weight measures. The collective results reveal that early life LCS consumption alters sugar preference, body weight, and gene expression for markers of thermogenesis during adulthood, with both sex- and sweetener-dependent effects.

Consumption of low-calorie sweeteners: findings from the Campinas Nutrition and Health Survey.

We used data from the Campinas Health Survey (ISACamp 2014/15) and the Food Consumption and Nutritional Status Survey (ISACamp-Nutri 2015/16) to estimate the prevalence of the consumption of foods and beverages that contain low-calorie sweeteners (LCS) by individuals ≥ 10 years to estimate the dietary exposure of the population to high levels of LCS. We first estimated the prevalence of consuming LCS-containing foods and beverages and identified the top sources of LCS consumption. We then verified whether the prevalence of consumption varied according to individual-level characteristics or the presence of obesity and diabetes. Finally, we estimated the population dietary exposure to high levels of LCS and compared it with the acceptable daily intake (ADI) levels. Over 40 % of the study population consumed at least one LCS-containing food or beverage. Sweetened beverages, tabletop sweeteners and dairy beverages were the top contributors to the consumption of LCS. Among all age groups, education levels, and income levels, the consumption of LCS-containing foods and beverages ranged from 35 % to 55 %. The prevalence was only slightly greater among higher income 40-59-year-olds than among other income groups and was not higher among individuals with obesity or diabetes. Although dietary exposure to LCS did not exceed the ADI levels, we identified several limitations in our ability to measure exposure to high levels of LCS. Because of these challenges and the unclear evidence linking LCS to better health outcomes, the consumption of LCS-containing foods and beverages should be closely monitored.

1247Low-calorie sweeteners consumption: a population-based study from Campinas, Brazil

Abstract Background The addition of low-calorie sweeteners (LCS) has been increasingly used by industry but their metabolic effects are controversial. Objectives: to estimate the consumption of foods and beverages with LCS among adolescents, adults and the elderly and to verify which food categories most contribute to this consumption. Methods Cross-sectional study. We used data from the Campinas Health Survey (ISACamp 2014-15) and the Food Consumption and Nutritional Status Survey (ISACamp-Nutri 2015-16) of 2570 individuals from 10 years old. We estimated the prevalence of LCS consumption and described the food categories that most contributed to this consumption. Using regression analysis, we verified which population groups had the highest consumption of products with LCS. Results More than 40% of adolescents, adults and the elderly consumed at least one product with LCS, mainly coming from sweetened beverages, tabletop sweeteners, and yogurt and other dairy beverages. The consumption of LCS was evenly found across adolescents and elderly from all socioeconomic strata, and whether elderly participants presented overweight and/or diabetes. Among adults, greater prevalence of foods and beverages with LCS consumption was found in those with higher education but did not vary by the presence of overweight and/or diabetes. Conclusions We found similar consumption of foods and beverages with LCS in most socioeconomic strata, and in participants with and without overweight or diabetes. Key messages The results can contribute to the development of public policies on clearer information of LCS addition in food labels.

Dietary and Health Correlates of Sweetened Beverage Intake: Sources of Variability in the National Health and Nutrition Examination Survey (NHANES).

Recent studies using data from the National Health and Nutrition Examination Survey (NHANES) have used inconsistent approaches to identify and categorize beverages, especially those containing low-calorie sweeteners (LCS), also referred to as low-calorie sweetened beverages (LCSBs). Herein, we investigate the approaches used to identify and categorize LCSBs in recent analyses of NHANES data. We reviewed published studies examining LCS consumption in relation to dietary and health outcomes and extracted the methods used to categorize LCS as reported by the authors of each study. We then examined the extent to which these approaches reliably identified LCSBs using the Internet Archive Wayback Machine to examine beverage ingredients lists across three NHANES cycles (2011–2016). None of the four general strategies used appeared to include all LCSBs while also excluding all beverages that did not contain LCS. In some cases, the type of sweetener in the beverage consumed could not be clearly determined; we found 9, 16, and 18 of such “mixed” beverage identifiers in the periods 2011–2012, 2013–2014, and 2015–2016, respectively. Then, to illustrate how heterogeneity in beverage categorization may impact the outcomes of published analyses, we compared results of a previously published analysis with outcomes when “mixed” beverages were grouped either all as LCSBs or all as sugary beverages. Our results suggest that caution is warranted in design and interpretation of studies using NHANES data to examine dietary and health correlates of sweetened beverage intake.

A Novel Urinary Biomarker Approach Reveals Widespread Exposure to Multiple Low-CalorieSweeteners in Adults

Observational investigations into the health impacts of low-calorie sweeteners (LCSs) in humans fail to adequately identify or fully characterize LCS consumption. We aimed to utilize a novel biomarker approach to investigate exposure to 5 LCSs and to test whether reported low-calorie sweetened beverage (LCSB) consumption effectively identifies exposure to LCSs in adults. In this cross-sectional analysis, 2 population studies were conducted in adults. Urinary excretions of 5 LCSs, namely acesulfame-K, saccharin, cyclamate, sucralose, and steviol glycosides, were simultaneously determined using LC tandem-MS. In Study 1, previously collected 24-h urine samples (n=357) were analyzed. In Study 2, previously collected 24-h urine samples (n=79) were analyzed to compare urinary excretions of LCSs with self-reported LCSB consumption for identifying LCS exposure. Exposure to LCSs was characterized using descriptive statistics and chi-square tests were performed to assess associations between age-groups and LCS excretion, and to assess the proportion of individuals identified as LCS consumers using biomarker data or reported LCSB consumption. A total of 341 adults (45% men) and 79 adults (39% men) were included in the final analysis of Studies 1 and 2, respectively. In Study 1, >96% of samples contained ≥1 LCS and almost 60% contained ≥3 LCSs. A greater proportion of younger adults (<40 y old) excreted ≥3 LCSs than older adults (>40 y old) (P <0.001). In Study 2, a much higher prevalence of LCS consumption was observed using biomarker data (92%) than reported LCSB consumption (6%) (P <0.001). This work indicates widespread exposure to LCSs, suggesting that population-based research to date into LCS exposure and health may be flawed. Therefore, a urinary biomarker approach offers considerable potential for more robust investigations in this area.

Daily Eating Frequency in US Adults: Associations with Low-Calorie Sweeteners, Body Mass Index, and Nutrient Intake (NHANES 2007-2016).

Studies of relationships between eating frequency and/or timing and energy intake have not examined associations with low-calorie sweeteners (LCS). We assessed the frequency of eating behavior related to LCS consumption emphasizing timing, calorie intake, and body mass index (BMI) among United States (US) adults aged ≥19 years. Using the National Health and Nutrition Examination Survey (NHANES) 2007–2016, we defined eating episodes as food and/or beverage intake within 15 min of one another over the first 24-h dietary recall. We coded items ingested during episodes (n = 136,938) and assessed LCS presence using US Department of Agriculture (USDA) food files. Episode analysis found intakes of foods only (27.4%), beverages only (29.5%), and foods with beverages (43.0%). LCS items were consumed without concurrent calories from other sources in fewer than 2.7% of all episodes. Within participants having normal weight (29.4%), overweight (33.6%) and obese (37.1%) BMIs, LCS consumers (35.2% overall) evidenced: more episodes/day; and fewer: calories, carbohydrates, fats, and protein per episode. Per person, those consuming LCS had lower total calories and higher fiber intake per day. LCS consumption was associated with higher BMI. Number of eating episodes/day and longer hours when eating episodes occurred were also consistently associated with higher BMI. Consuming LCS did not modify these relationships. These results did not show that LCS consumption was associated with increased caloric intake from other dietary sources.

The controversial effects of low-calorie sweeteners

Substantial reviews of the most recent evidence report a strong relationship between the consumption of sugar-sweetened beverages and adverse health effects, such as the prevalence of obesity and metabolic diseases. Various public policies were recently undertaken by many countries in the hope of reducing sugar-sweetened beverage consumption amongst their population. This has led the food industries to promote low-calorie sweeteners (sugar substitutes) as a healthy alternative that would limit caloric intake without compromising the sweet taste of food and beverages. However, is the use of low-calorie sweeteners as a means of limiting or reducing energy intake without consequences for our health? This review aims to discuss the effects of low-calorie sweeteners consumption on health and to elucidate whether their use should be recommended by health professionals to their patients as part of weight management.

Low-calorie sweeteners cause only limited metabolic effects in mice.

There are widespread concerns that low-calorie sweeteners (LCSs) cause metabolic derangement. These concerns stem in part from prior studies linking LCS consumption to impaired glucose tolerance in humans and rodents. Here, we examined this linkage in mice. In experiment 1, we provided mice with chow, water, and an LCS-sweetened solution (saccharin, sucralose, or acesulfame K) for 28 days and measured glucose tolerance and body weight across the exposure period. Exposure to the LCS solutions did not impair glucose tolerance or alter weight gain. In experiment 2, we provided mice with chow, water, and a solution containing saccharin, glucose, or a mixture of both for 28 days, and tested for metabolic changes. Exposure to the saccharin solution increased the insulinemic response of mice to the glucose challenge, and exposure to the saccharin + glucose solution increased the rate of glucose uptake during the glucose challenge. However, neither of these test solutions altered glucose tolerance, insulin sensitivity, plasma triglycerides, or percent body fat. In contrast, exposure to the glucose solution increased glucose tolerance, early insulin response, insulin sensitivity, and percent body fat. We conclude that whereas the LCS-containing solutions induced a few metabolic changes, they were modest compared with those induced by the glucose solution.

Low-calorie sweetener use, weight, and metabolic health among children: A mini-review.

A reduction in the consumption of added sugars and sugar-sweetened beverages (SSBs) is a key focus of public health recommendations for a healthy diet among children. One approach to lower added sugar intake is to instead use low-calorie sweeteners (LCSs), which contain no or few calories. Consumption of LCSs is increasing worldwide, with the most marked rise observed among children and adolescents. However, the extent to which LCS consumption is helpful or harmful for weight management is controversial, particularly when LCS consumption begins in childhood. Herein, we summarize the limited existing literature examining effects of paediatric LCS consumption on appetite, energy intake, and body weight. While positive associations between LCS consumption and weight gain are reported in observational analyses, the majority of intervention studies, some of which blinded children to the contents of the drinks, report benefits of LCSs for reducing excessive child weight gain. Several potential mechanisms have been proposed to explain LCS effects on body weight, including LCS-induced promotion of appetite and energy intake. Yet studies assessing effects of beverages with LCSs (LCSBs) compared with SSBs on child appetite report mixed findings. Some demonstrate that children completely compensate for the diluted energy content of LCSBs by eating more solid food calories at subsequent meals compared with children administered SSBs, while others report a reduction in total energy intake with LCSB ingestion. Given the limited studies and resulting uncertainty as to whether LCSs benefit or worsen weight and metabolic health in children is integral that effects of LCS use during childhood continue to be investigated in future prospective studies.

Trends in Low-Calorie Sweetener Consumption Among Pregnant Women in the United States

ABSTRACTBackgroundMinimizing consumption of added sugars is recommended to prevent excessive weight gain among pregnant women. A common approach to lowering sugar intake is the use of low-calorie sweeteners (LCSs), yet little is known about LCS use during pregnancy or its effects on infant weight and health.ObjectiveThe aim of the study was to investigate temporal trends in LCS consumption by source (foods, beverages, or packets) among pregnant women in the United States from 1999 to 2014 and to compare recent LCS consumption patterns across sociodemographic subgroups and product categories.MethodsData were collected from pregnant women aged 20–39 y (n = 1,265) who participated in the NHANES from 1999–2000 through 2013–2014. Prevalence of LCS consumption was assessed using two 24-h dietary recalls. Analytical procedures for complex survey design were used, and sampling weights were applied to estimate national prevalence of LCS use. Rao–Scott modified chi-square tests were used to compare consumption prevalence across sociodemographic subgroups, and logistic regression was used to examine trends in LCS use over time.ResultsThe prevalence of LCS consumption among pregnant women increased by approximately 50% rising from 16.2% in 1999–2004 to 24.0% in 2007–2014, P = 0.04, with the highest prevalence observed in 2005–2006 (38.4%). This trend was driven predominantly by increases in LCS beverage use (9.9% in 1999–2004 compared with 18.3% in 2007–2014, P = 0.02). Prevalence of LCS consumption was highest among non-Hispanic white women and increased with education and income. No differences were observed based on prepregnancy weight status or trimester of pregnancy.ConclusionsApproximately one-quarter of pregnant women in the United States reported consumption of LCS during at least 1 of 2 dietary recalls. Given the widespread LCS consumption during pregnancy, research to elucidate potential effects of early life LCS exposure on taste preferences, weight trajectory, and risk of later metabolic disease is needed.

SWEET MAPS: A Conceptualization of Low-Calorie Sweetener Consumption Among Young Adults

ABSTRACTBackgroundThe extent to which low-calorie sweeteners (LCSs) are helpful or harmful for weight management and metabolic health is unclear, because LCS effects may depend on the context in which they are consumed.ObjectiveTo develop a conceptual framework for LCS consumption.MethodsYoung adults ages 18–35 y, who reported LCS consumption, were recruited from a private, urban, university in the mid-Atlantic United States. Concept mapping, a mixed-method approach was used to identify, organize, and quantify determinants of LCS consumption. First, participants (n = 68) identified reasons for their LCS consumption through brainstorming; content analysis of those reasons identified 37 specific determinants of LCS consumption. Second, participants (n = 93) sorted all 37 determinants conceptually. Third, participants (n = 97) rated the extent to which each of the 37 determinants was reflective of their own consumption. Similarity matrices, multidimensional scaling, and hierarchical cluster analysis produced a series of 2-dimensional concept maps (SWEET MAPS).ResultsThe SWEET MAPS identified 37 determinants, organized within 8 factors reflective of 3 overarching motives: perceived health benefits, palatability, and accessibility of LCSs. At the determinant level, the most highly rated determinants that exceeded the boundary (rating >3.0) were: “I want something that tastes sweet,” “I am trying to maintain/control my weight,” “They contain fewer calories,” “They are available,” and “I want to save calories because I am eating a high-calorie meal.”ConclusionsLCS consumption is a function of many inter-related determinants spanning biological, psychological, and social domains. The SWEET MAPS are an important and novel use of concept mapping methods that can be used to inform the design and interpretation of future studies evaluating LCS effects.

Low-Calorie Sweetened Beverages and Cardiometabolic Health: A Science Advisory From the American Heart Association.

In the United States, 32% of beverages consumed by adults and 19% of beverages consumed by children in 2007 to 2010 contained low-calorie sweeteners (LCSs). Among all foods and beverages containing LCSs, beverages represent the largest proportion of LCS consumption worldwide. The term LCS includes the 6 high-intensity sweeteners currently approved by the US Food and Drug Administration and 2 additional high-intensity sweeteners for which the US Food and Drug Administration has issued no objection letters. Because of a lack of data on specific LCSs, this advisory does not distinguish among these LCSs. Furthermore, the advisory does not address foods sweetened with LCSs. This advisory reviews evidence from observational studies and clinical trials assessing the cardiometabolic outcomes of LCS beverages. It summarizes the positions of government agencies and other health organizations on LCS beverages and identifies research needs on the effects of LCS beverages on energy balance and cardiometabolic health. The use of LCS beverages may be an effective strategy to help control energy intake and promote weight loss. Nonetheless, there is a dearth of evidence on the potential adverse effects of LCS beverages relative to potential benefits. On the basis of the available evidence, the writing group concluded that, at this time, it is prudent to advise against prolonged consumption of LCS beverages by children. (Although water is the optimal beverage choice, children with diabetes mellitus who consume a balanced diet and closely monitor their blood glucose may be able to prevent excessive glucose excursions by substituting LCS beverages for sugar-sweetened beverages [SSBs] when needed.) For adults who are habitually high consumers of SSBs, the writing group concluded that LCS beverages may be a useful replacement strategy to reduce intake of SSBs. This approach may be particularly helpful for persons who are habituated to a sweet-tasting beverage and for whom water, at least initially, is an undesirable option. Encouragingly, self-reported consumption of both SSBs and LCS beverages has been declining in the United States, suggesting that it is feasible to reduce SSB intake without necessarily substituting LCS beverages for SSBs. Thus, the use of other alternatives to SSBs, with a focus on water (plain, carbonated, and unsweetened flavored), should be encouraged.

Prevalence of low-calorie sweetener intake in South Asian adults.

Consumption of low-calorie sweeteners (LCS) has increased in the US and is associated with cardiometabolic risk. No data exist on LCS consumption in South Asians. The aim of this study was to assess the prevalence of LCS use across socio-demographic characteristics, chronic disease status, and cardiometabolic risk factors. Cross-sectional analyses were conducted using data from the Mediators of Atherosclerosis in South Asians Living in America study (N = 892; 47% women; mean age = 55 (standard deviation = 9.4) y). Chi-squared and ANOVA tests were used to compare LCS consumption across socio-demographic characteristics and cardiometabolic risk factors. Twenty-two percent of participants reported LCS use, with higher consumption among men and those with longer residency in the US. LCS use was associated with adiposity and higher odds of hypertension, high cholesterol, and diabetes. LCS use is prevalent among South Asians, emphasizing the need for long-term, prospective studies to investigate its role in incident cardiometabolic risk in an already metabolically vulnerable population.
