Association between consumption of sweeteners and endometrial cancer risk: a systematic review and meta-analysis of observational studies.

The purpose of this study is to further investigate the relationship between sweetener exposure and the risk of endometrial cancer (EC). Up until December 2022, a literature search in an electronic database was carried out utilizing PubMed, Web of Science, Ovid, and Scopus. The odds ratio (OR) and 95 % confidence interval (CI) were used to evaluate the results. Sweeteners were divided into nutritional sweeteners (generally refers to sugar, such as sucrose and glucose) and non-nutritional sweeteners (generally refers to artificial sweeteners, such saccharin and aspartame). Ten cohort studies and two case-control studies were eventually included. The study found that in 12 studies, compared with the non-exposed group, the incidence rate of EC in the sweetener exposed group was higher (OR = 1·15, 95 % CI = [1·07, 1·24]). Subgroup analysis showed that in 11 studies, the incidence rate of EC in the nutritional sweetener exposed group was higher than that in the non-exposed group (OR = 1·25, 95 % CI = [1·14, 1·38]). In 4 studies, there was no difference in the incidence rate of EC between individuals exposed to non-nutritional sweeteners and those who were not exposed to non-nutritional sweeteners (OR = 0·90, 95 % CI = [0·81, 1·01]). This study reported that the consumption of nutritional sweeteners may increase the risk of EC, whereas there was no significant relationship between the exposure of non-nutritional sweeteners and the incidence of EC. Based on the results of this study, it is recommended to reduce the intake of nutritional sweeteners, but it is uncertain whether use of on-nutritional sweeteners instead of nutritional sweetener.

Non-nutritive sweetened beverages versus water after a 52-week weight management programme: a randomised controlled trial.

BACKGROUND/OBJECTIVE: Sugar-sweetened beverages are a substantial source of dietary sugar that can contribute to weight gain and the risk of type 2 diabetes. Dietary guidelines recommend non-nutritive sweetened (NNS) beverages to reduce sugar consumption, however, there is a need for long-term randomised controlled trials on their use. We aimed to compare the effects of NNS beverages and water on body weight during weight loss and maintenance in a behavioural weight management programme. METHODS: In this parallel-group, open-label, controlled equivalence trial, adults with a BMI of 27-35 kg/m2 who regularly consumed cold beverages were randomised 1:1 to water or NNS beverages. Participants underwent a group behavioural weight management programme comprising weekly (during the 12-week weight-loss phase) then monthly (during the 40-week weight-maintenance phase) meetings. The primary endpoint was weight change at week 52 (equivalence: two-sided P > 0.05). Secondary endpoints included changes in anthropometrics, cardiometabolic risk factors, appetite and activity levels. RESULTS: Of 493 participants randomised (water: n = 246; NNS beverages: n = 247), 24.1% were NNS-naïve. At week 52, water and NNS beverages were non-equivalent, with significantly greater weight loss in the NNS beverages group. Participants consuming water maintained a weight loss of 6.1 kg over 52 weeks versus 7.5 kg with NNS beverages (difference [90% CI]: 1.4 kg [-2.6, -0.2]; p < 0.05). CONCLUSIONS: During a 52-week behavioural weight management programme, water and NNS beverages were non-equivalent, with weight loss maintained to a statistically greater extent with NNS beverages compared with water. However, this difference was not clinically significant. CLINICAL TRIAL REGISTRATION: This trial is registered with ClinicalTrials.gov: NCT02591134.

Effect of low-and non-calorie sweeteners on the gut microbiota: A review of clinical trials and cross-sectional studies.

Use of non-nutritive sweeteners (NNSs) has increased worldwide in recent decades. However, evidence from preclinical studies shows that sweetener consumption may induce glucose intolerance through changes in the gut microbiota, which raises public health concerns. As studies conducted on humans are lacking, the aim of this review was to gather and summarize the current evidence on the effects of NNSs on human gut microbiota. Only clinical trials and cross-sectional studies were included in the review. Regarding NNSs (i.e, saccharin, sucralose, aspartame, and stevia), only two of five clinical trials showed significant changes in gut microbiota composition after the intervention protocol. These studies concluded that saccharin and sucralose impair glycemic tolerance. In three of the four cross-sectional studies an association between NNSs and the microbial composition was observed. All three clinical trials on polyols (i.e, xylitol) showed prebiotic effects on gut microbiota, but these studies had multiple limitations (publication date, dosage, duration) that jeopardize their validity. The microbial response to NNSs consumption could be strongly mediated by the gut microbial composition at baseline. Further studies in which the potential personalized microbial response to NNSs consumption is acknowledged, and that include longer intervention protocols, larger cohorts, and more realistic sweetener dosage are needed to broaden these findings.

Associated factors to the consumption of non-nutritive sweeteners in the Mexican adult population.

OBJECTIVE: To identify the associated factors to the consumption of non-nutritive sweeteners (NNS) in the Mexican adult population since its consumption has increased exponentially worldwide. MATERIALS AND METHODS: An online survey was applied to 5 038 Mexican adults to evaluate the frequency of NNS consumption and classify the population in tertiles. The sociodemographic, lifestyle and health status characteristics of the participants were compared by gradient of NNS consumption, and a multiple linear regression analysis was performed to determine the associated factors to the NNS consumption. RESULTS: The variables that showed a positive association (p≤0.01) with the consumption of NNS were economic income, BMI, smoking, physical activity, diet quality, the presence of chronic diseases (diabetes, hypertension, or dyslipidemias), and the consumption of fruit. The age and the consumption of confectionery and sugar-sweetened beverages were negatively associated (p<0.01) with the consumption of NNS. CONCLUSION: The results of this study help to characterize the target population that is a consumer of NNS since it is recommended not encourage the preference for sweet taste and to promote a decrease in the consumption of both caloric and NNS, preferring the natural flavor of food.

Nutritive/non-nutritive sweeteners and high fat diet contribute to dysregulation of sweet taste receptors and metabolic derangements in oral, intestinal and central nervous tissues.

OBJECTIVES: Overconsumption of non-nutritive sweeteners is associated with obesity, whereas the underlying mechanisms remain controversial. This study aimed to investigate the effects of long-term consumption of nutritive or non-nutritive sweeteners with or without high fat diet on sweet taste receptor expression in nutrient-sensing tissues and energy regulation dependent on sweet-sensing. METHODS: 50 Male Sprague-Dawley rats (140-160 g) were assigned to 10 groups (n = 5/group). All received fructose at 2.5% or 10%, sucralose at 0.01% or 0.015% or water with a normal chow diet or high fat diet for 12 weeks. Food and drink intake were monitored daily. Oral glucose tolerance test and intraperitoneal glucose tolerance test were performed at week 10 and 11 respectively. Serum was obtained for measurement of biochemical parameters. Tongue, duodenum, jejunum, ileum, colon and hypothalamus were rapidly removed to assess gene expression. RESULTS: Long-term consumption of sweeteners impaired glucose tolerance, increased calorie intake and body weight. A significant upregulation of sweet taste receptor expression was observed in all the four intestinal segments in groups fed 0.01% sucralose or 0.015% sucralose, most strikingly in the ileum, accompanied by elevated serum glucagon-like peptide-1 levels and up-regulated expression of sodium-dependent glucose cotransporter 1 and glucose transporter 2. A significant down-regulation in the tongue and hypothalamus was observed in groups fed 10% fructose or 0.015% sucralose, with alterations in hypothalamic appetite signals. The presence of high fat diet differentially modulates sweet taste perception in nutrient-sensing tissues. CONCLUSIONS: Long-term consumption of whether nutritive sweeteners or non-nutritive sweeteners combined with high fat diet contribute to dysregulation of sweet taste receptor expression in oral, intestinal and central nervous tissues.

Non-Nutritive Sweetened Beverages Impair Therapeutic Benefits of Metformin in Prediabetic Diet-Induced Obese Mice.

Metformin, a frontline therapy for type 2 diabetes and related metabolic diseases, results in variable outcomes. This study aimed to investigate whether sweetened beverages (caloric or non-caloric) affect the therapeutic benefits of metformin on glucose, food intake, and weight loss in diet-induced obesity. Mice were given a high-fat diet and sweetened water for 8 weeks to induce obesity and glucose intolerance. Then, mice were randomized to receive metformin in either water, high-fructose corn syrup (HFCS), or the non-nutritive sweetener saccharin for 6 weeks. After 6 weeks of metformin treatment, all groups had improved glucose tolerance compared to pretreatment. However, saccharin resulted in worse glucose tolerance and weight gain outcomes than the water or HFCS groups and correlated with lower plasma growth differentiation factor 15 levels. In conclusion, reducing non-nutritive sweetener consumption during metformin therapy is recommended to avoid impairing the therapeutic effects of metformin on body weight and glucose homeostasis.

Acute Adverse Effects Related to Consumption of Nonnutritive and Low-Calorie Sweeteners.

Nonnutritive sweeteners (NNSs) and low-calorie sweeteners (LCSs) are commonly used as sugar substitutes. Many popular media Web sites caution against the use of these sweeteners because of their potential adverse effects such as inflammation; however, there are limited supporting data. A Medline search of articles published between 2010 and 2020 was conducted, resulting in 833 articles, of which 12 relevant studies were included in this review. Acute adverse effects associated with the consumption of NNSs and LCSs are rare. A few studies cite reports of acute adverse effects, including mild gastrointestinal disturbance, headaches, lightheadedness, hypersensitivity reactions, impaired spatial orientation, depression, and pain. Little scientific evidence has been reported in the literature since 2010 to support these warning statements to consumers about acute adverse effects to NNSs and LCSs.

Association between non-nutritive sweetener consumption and liver enzyme levels in adults: a systematic review and meta-analysis of randomized clinical trials.

CONTEXT: The use of non-nutritive sweeteners (NNSs) is dramatically increasing in food commodities, and their effects on biochemical parameters have been the subject of great controversy. Liver enzymes as markers of liver injury may be helpful measures of non-alcoholic fatty liver disease (NAFLD), but the outcomes of randomized controlled trials (RCTs) suggest their associations with NNSs are contentious. OBJECTIVE: The current study was designed to provide a GRADE-assessed systematic review and meta-analysis of RCTs studying the consequences of NNS consumption on ALT, AST, and GGT concentrations (ie, the 3 main liver enzymes in adults). DATA SOURCES: Scopus, PubMed, and EMBASE were searched for relevant studies up to April 2021, with no time and language limitations. DATA EXTRACTION: Two independent researchers extracted information from qualified studies, and a third researcher rechecked it. DATA ANALYSIS: Of 3212 studies, 10 studies that enrolled a total of 854 volunteers were included. A random-effects or fixed-effects model was utilized to calculate weighted mean differences (WMDs) and 95% confidence intervals (CIs). Heterogeneity between studies was evaluated using Cochran's Q test and quantified using the I2 statistic. The pooled results demonstrated that, compared with control groups, NNS intake led to nonsignificant reductions in ALT (WMD: -.78, 95% CI: -2.14, .57, P = .25) and GGT (WMD: -.21, 95% CI: -1.46, 1.04, P = .74). Also, a small nonsignificant increasing effect on AST level was found (WMD: .02, 95% CI: -1.26, 1.30, P = .97). NNS significantly reduced AST levels in type 2 diabetes patients when subgroup analyses were performed. Also, in trials with ≥24-week intervention or studies that utilized stevioside for intervention, a significant reducing effect on ALT level was observed. CONCLUSION: The results of this study showed that NNS intake has no significant effect on liver enzyme levels in adults. SYSTEMATIC REVIEW REGISTRATION: PROSPERO registration no. CRD42021250067.

Non-Nutritive Sweeteners in Human Amniotic Fluid and Cord Blood: Evidence of Transplacental Fetal Exposure.

OBJECTIVE: This study aimed to investigate human fetal exposure to non-nutritive sweeteners (NNS) by analyzing amniotic fluid and umbilical cord blood. STUDY DESIGN: Concentrations of four NNS (acesulfame-potassium [ace-K], saccharin, steviol glucuronide, and sucralose) were measured in amniotic fluid (n = 13) and cord blood samples (n = 15) using liquid chromatography-mass spectrometry. Amniotic fluid samples were obtained for research purposes at the time of term elective cesarean birth or clinically indicated third trimester amnioreduction at Mercy Hospital for Women (Melbourne, Australia). All except four women were in the fasting state. Cord blood samples were obtained from an independent cohort of newborns whose mothers were enrolled in a separate clinical trial at the National Institutes of Health. RESULTS: Ten of 13 amniotic fluid samples contained at least one NNS (ace-K, saccharin, steviol glucuronide, and/or sucralose). Maximum amniotic fluid NNS concentrations of ace-K, saccharin, steviol glucuronide, and sucralose were 78.9, 55.9, 93.5, and 30.6 ng/mL, respectively. Ace-K and saccharin were present in 100% and 80% of the cord blood samples, with maximal concentrations of 6.5 and 2.7 ng/mL, respectively. Sucralose was not detected and steviol glucuronide was not measurable in any of the cord blood samples. CONCLUSION: Our results provide evidence of human transplacental transmission of NNS. Based on results predominantly obtained from rodent models, we speculate that NNS exposure may adversely influence the offsprings' metabolic health. Well-designed, prospective clinical trials are necessary to understand the impact of NNS intake during pregnancy on human development and long-term health. KEY POINTS: · NNS consumption during pregnancy has increased in recent years.. · Maternal NNS intake during pregnancy is associated with preterm birth and higher infant weight gain in epidemiologic studies.. · In rodents, in utero NNS exposure induces metabolic abnormalities in mothers and their offspring, alters offspring gut microbiota composition, and promotes sweet taste preference in adulthood.. · It is presently unknown whether and to what degree maternal NNS ingestion in humans leads to direct in utero exposure.. · This study provides the first evidence of in utero NNS exposure in humans and highlights the urgent need to investigate clinical consequences of early life NNS exposure on metabolism, weight, taste preference, and general health..

Consumption of Non-Nutritive Sweetener during Pregnancy and Weight Gain in Offspring: Evidence from Human Studies.

The relationship between the consumption of maternal non-nutritive sweeteners (NNS) during pregnancy and the risk of obesity in offspring remains inconsistent. We aimed to systematically evaluate and clarify the relationship between NNS intake during pregnancy and weight gain in offspring based on evidence from population and clinical research. Databases including PubMed (via Medline), EMBASE, and the Cochrane Library were systematically searched for eligible human studies. The primary outcome was the differences in body mass index (BMI) z-scores between offspring at 1 year of age who were with and without NNS intake during pregnancy or between offspring with different NNS intake levels during pregnancy. A random-effects meta-analysis was conducted for data synthesis to calculate the weighted mean difference (WMD). A total of six prospective cohort studies were eligible for inclusion, among which three were used for pooled analysis of the BMI z-score. A significant increase was found in an offspring's weight at 1 year of age in the NNS group when compared with the control group: WMD in BMI z-score = 0.19 (95% CI: 0.07, 0.31), p-value = 0.002. Results from the dose-response analysis showed a linear relationship between NNS intake during pregnancy and WMD at 1 year of age: beta = 0.02 (95% CI: 0.001, 0.04) for per serving/week increase in NNS consumption. The whole body of evidence for the review was rated as low quality. In summary, maternal NNS intake during pregnancy was found to be associated with increased weight gain in offspring based on evidence from human studies. Further well-designed and adequately powered studies are needed to confirm this relationship.

Beliefs concerning non-nutritive sweeteners consumption in consumers, non-consumers, and health professionals: a comparative cross-sectional study.

Introduction: Introduction: the consumption of non-nutritive sweeteners (NNS) has increased. Recent studies have reported possible metabolic effects of NNS, and this may influence the perception regarding their consumption in the general population and health professionals. Objective: to describe and compare the beliefs about NNS in consumers, non-consumers, and health professionals; and to explore the reasons and opinions of health professionals for recommending or not their consumption. Methods: surveys were applied to 100 consumers, 100 non-consumers and 100 health professionals (dietitians and physicians) to evaluate a positive, negative, or neutral attitude towards certain beliefs regarding NNS, including the information they have, safety, price, side effects and taste. In addition, the opinion of health professionals for recommending or not the consumption of NNS and the related reasons was evaluated. Results: statistically significant differences regarding the safety, side effects and taste of NNS were found between the three groups (p < 0.01). The most frequent opinion of health professionals (48 %) is that NNS should be limited, used as a transition and in certain patients. Consumers tend to have a more positive opinion about NNS except for the price, non-consumers have a more neutral position except for taste, and health professionals have a more negative perception of NNS in all aspects. Conclusions: the beliefs regarding NNS differed among the studied groups, which might influence their consumption or recommendation of its use.

Objetivo: describir y comparar las creencias sobre los ENN en consumidores, no consumidores y profesionales de la salud, así como conocer las principales opiniones de los profesionales de la salud para recomendar o no el consumo de ENN. Métodos: se aplicaron encuestas a 100 consumidores, 100 no consumidores y 100 profesionales de la salud (nutriólogos y médicos) para evaluar actitudes positivas, negativas o neutras en torno a ciertas creencias de los ENN, la información que creen tener, seguridad, precio, efectos secundarios y sabor. Además, se evaluó la opinión de los profesionales de la salud para recomendar o no su consumo y las razones asociadas. Resultados: se encontraron diferencias entre los tres grupos en torno a la seguridad, los efectos secundarios y el sabor de los ENN (p < 0.01). La postura más frecuente de los profesionales de la salud (48 %) es que los ENN deben limitarse, utilizarse transitoriamente y en ciertos pacientes. Se observó una postura más positiva con respecto a los ENN en los consumidores excepto por su precio, más neutral en los no consumidores excepto por su sabor y más negativa en los profesionales de la salud en todos los aspectos. Conclusiones: las creencias sobre los ENN difieren entre los grupos estudiados, lo cual puede influir en su consumo o en la recomendación de su uso.

A gut reaction: Microbiome-driven glycemic effects of non-nutritive sweeteners.

Non-nutritive sweeteners are increasingly consumed to satisfy cravings for sweet taste without the associated calories. Paradoxically, non-nutritive sweeteners have been linked to metabolic risks, but the underlying mechanisms are not understood. In this issue of Cell, Suez and colleagues pinpoint changes in the gut microbiome as a mechanism for non-nutritive sweetener-induced glycemic impairments in healthy adults.

Effect of Long-Term Intake of Nutritive and Non-Nutritive Sweeteners on Metabolic Health and Cognition in Adult Male Rats.

This study evaluated the effects of long-term intake of nutritive sweeteners (NSs) and non-nutritive sweeteners (NNSs) on body weight, food and energy intake, blood pressure, metabolic parameters, and memory retention in rats. Sixty male Sprague-Dawley rats were randomly divided into six groups (n = 10 per group): control (water),10% sucrose (SUC), aspartame (ASP), sucralose (SCA), stevia (STV), and 5% xylitol (XYL). Pure NSs (SUC and XYL) and NNSs were added to the drinking water for 18 weeks. ASP, SCA, and STV dosage was based on the estimated daily intake limit: 4.1, 2.0, and 3.4 mg/kg/day, respectively. Chronic access to NNSs did not result in any difference in total weight gain of the rats, while it was significantly elevated in the SUC group compared with the control and NNSs groups. Food intake was significantly lower in all NNSs groups compared with SUC and control groups. Sweetened beverage intake volumes were significantly diminished in all NNSs groups compared with intake in SUC and control groups. Total calories consumed were lower for the STV and XYL groups compared with all other groups. Blood pressure and glucose metabolism did not differ significantly between the groups. All sweeteners increased total cholesterol, low-density lipoprotein, and triglyceride levels. Short-term memory was significantly impaired in the ASP group in the novel object recognition task, while long-term memory was impaired in SUC and STV groups. These metabolic and behavioral results suggest that the long-term intake of NSs or NNSs can be associated with peripheral and central effects.

An Ecological Validity Model for the Prevention of Obesity: Non-Nutritive Sweetener Consumption in Rats and the Effects of Switching from Sugar-Sweetened to Diet Beverages.

Reducing consumption of sugar-sweetened beverages (SSBs) has been encouraged due to its strong association with obesity. In parallel, consumption of "diet" or non-nutritive sweetened (NNS) beverages has significantly increased. This has led to burgeoning numbers of animal studies investigating metabolic consequences of NNS beverage consumption. However, most animal study designs do not reflect the way humans consume NNS drinks, thus reducing translational capacity. The present experiment aimed to find an ecologically valid model of NNS consumption and evidence of metabolic recovery following a switch from sucrose to NNS in female and male Sprague Dawley rats. The main behavioural outcome was consumption of commercially available NNS beverages during preference and acceptance testing, with changes to consumption following chronic sucrose consumption as a secondary outcome. The main metabolic outcome was retroperitoneal fat pad mass at culling, with body weight gain and fasting blood glucose levels (FBGLs) as secondary outcomes. In a two-phase experiment, behavioural tests were performed before and after 4 weeks of ad libitum access to 10% w/v sucrose. During Phase 2, the rats were given ad libitum access to assigned commercial NNS drinks for a further 4 weeks, with controls provided access to water only. FBGLs were measured at the end of Phases 1 and 2. Female and male rats accepted commercially available NNS beverages, although the volumes consumed varied considerably. Following the switch from sucrose to NNS (containing no sucrose), no group difference was observed in retroperitoneal fat mass, body weight change or FBGLs, suggesting both sexes exhibited limited metabolic recovery. These findings demonstrate that an ecologically valid model for NNS consumption can be developed for some commercially available NNS beverages to further enhance translational capacity.

Clearing the Myths around non-nutritive/noncaloric Sweeteners: An Efficacy and Safety Evaluation.

Non-nutritive sweeteners (NNSs) are used to substitute sugar in the diet and are approved by the regulatory bodies in many countries, including the Food and Agriculture Organization (FAO)/the World Health Organization (WHO). Non-nutritive sweeteners are here to stay, as it is an effective strategy to reduce sugar and caloric intake which is a public health priority today. It is a tool to increase dietary compliance in the management of obesity and diabetes and is a partner for fitness seekers. However, the debate on its safety and efficacy continues, including several myths associated with its usage. This review has evaluated the scientific literature in-depth and concludes that NNSs are safe to use within an acceptable daily intake (ADI). Non-nutritive sweeteners are beneficial for their intended use, including weight management and diabetes control when consumed as a part of a dietary management program. The current data do not provide sufficient evidence that NNSs can affect the gut microbiome, and more research, particularly at relevant doses, is required. We also need more randomized control trials (RCTs) among the Indian population on the impact of sugar reduction with NNSs and its health benefits to strengthen the evidence for its use in medical nutrition management and preventive health, helping the individual make an informed choice.

Added sugars and non-nutritive sweeteners in the food supply: Are they a threat for consumers?

BACKGROUND & AIMS: Excess sugar intake can cause chronic diseases such as obesity, diabetes, and cardiovascular disease. Thus, limiting the intake of sugar in the diet is an important preventive measure. Food manufacturers have considered non-nutritive sweeteners (NNS) as an alternative to sugars. To date, there has been no systematic monitoring of the types of added sugars and NNS in Turkey's food supply. The aim of this study identified the added sugars and NNS in packaged foods and beverages that were available in supermarkets across Turkey. METHODS: A cross-sectional study was conducted from April to December 2020. Three supermarkets in Turkey were chosen for this study. RESULTS: Of the 2514 packaged foods and beverages analyzed, 1647 (65.5%) contained added sugars or NNS. Out of 1647 products, 9.7% contained both added sugars and NNS; 86.5% only added sugars whereas 3.8% had only NNS. The most used added sugar was white sugar in all food groups (50.6%-100%) while the most used NNS was sorbitol (28.4%). CONCLUSION: The use of added sugars and NNS in Turkey's food supply was found to be high, and white sugar being the most used sweetener in products available in the food supply. Therefore, it may be important to start monitoring the prevalence of products containing added sugars and NNS due to their negative health effects.
