RESUMO

Propagandas atraentes e preço baixo são estratégias das indústrias de bebidas açucaradas para atrair o consumidor e esconder os malefícios que esses produtos podem provocar para a saúde. Só no Brasil, mais de 1,3 milhão de casos de diabetes tipo 2 são devidos ao consumo de bebidas açucaradas, além de estarem associadas à obesidade, ao AVC e a outras doenças*.

RESUMO

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.

RESUMO

BACKGROUND: The consumption of artificially sweetened beverages (ASBs) has been linked to metabolic alterations. The effect of reducing the regular consumption of these beverages on the metabolism is currently unknown. OBJECTIVE: To evaluate the effect of reducing consumption of ASBs on the metabolism in overweight young adults. DESIGN: A randomised, single-blind, controlled, 12-week, clinical trial was performed in overweight young adults who regularly consume ASBs. The 45 subjects who participated in the study were randomly divided into two groups: (1) control group (n=21) and (2) intervention group (no intake of ASBs, n=24). Body weight and composition, fasting plasma concentrations of glucose, triglycerides, insulin, cholesterol, low-density lipoproteins and high-density lipoproteins were measured at the beginning and end of the study. and the HOMA-IR was calculated. RESULTS: At the end of 12 weeks, the intervention group showed a significant decrease (as opposed to an increase in the control group) in the percentage of change in body weight (-1.22% vs 1.31%, p<0.004), body fat (-6.28% vs 6.15%, p<0.001) and insulin resistance index (-12.06 vs 38.21%, p<0.00002), as well as in levels of glucose (-4.26% vs 0.51%, p<0.05), triglycerides (-14.74% vs 19.90%, p<0.006), insulin (-8.02% vs 39.23%, p<0.00005), cholesterol (-8.71% vs 0.77%, p<0.01) and LDL (-9.46% vs 9.92%, p<0.004). CONCLUSION: A reduction in habitual consumption of ASBs in overweight young adults decreases biochemical measurements, body weight and composition, suggesting a participation in the metabolic processes.

RESUMO

PURPOSE: To assess country-level trends in the prevalence of daily consumption of sugary (2002-2018) and diet (2006-2018) soft drinks among European adolescents, overall and by family material affluence. METHODS: We used 2002, 2006, 2010, 2014 and 2018 data from the 'Health Behaviour in School-aged Children' survey. Nationally representative samples of adolescents completed a standardised questionnaire at school, including a short food frequency questionnaire (n = 530,976 and 21 countries for sugary soft drinks; n = 61,487 and 4 countries for diet soft drinks). We classified adolescents into three socioeconomic categories for each country and survey year, using the Family Affluence Scale. Multilevel logistic models estimated time trends, by country. RESULTS: Sugary soft drinks: the prevalence of daily consumption (≥ 1×/day) declined in 21/21 countries (Plinear trends ≤ 0.002). Absolute [range - 31.7 to - 3.4% points] and relative [range - 84.8 to - 22.3%] reductions varied considerably across countries, with the largest declines in Ireland, England and Norway. In 3/21 countries, the prevalence of daily consumption decreased more strongly in the most affluent adolescents than in the least affluent ones (P ≤ 0.002). Daily consumption was more prevalent among the least affluent adolescents in 11/21 countries in 2018 (P ≤ 0.002). Diet soft drinks: overall, daily consumption decreased over time in 4/4 countries (Plinear trends ≤ 0.002), more largely among the most affluent adolescents in 1/4 country (P ≤ 0.002). CONCLUSIONS: Daily consumption of sugary and diet soft drinks in European adolescents decreased between 2002 (2006 for diet drinks) and 2018. Public health interventions should continue discouraging daily soft drink consumption, particularly among adolescents from lower socioeconomic groups.

RESUMO

BACKGROUND AND AIMS: Several studies have reported the association of sweetened beverages (SB) with cardiovascular disease. However, the relationship between SB and cardiovascular mortality has not been clearly established. This systematic review and meta-analysis investigated the association between SB consumption and cardiovascular mortality. METHODS: PubMed/MEDLINE, Web of Science, and Embase were systematically searched up to July 31, 2021, for prospective cohort studies investigating this association in adults. Pooled relative risks (RRs) and 95% confidence intervals (CIs) were used to assess the strength of association between SB: sugar-sweetened beverages (SSB)/artificial-sweetened beverages (ASB) exposure and cardiovascular mortality. RESULTS: A total of eight cohort studies comprising 1.2 million participants exposed to SB, reported 15,831 (1.2%) cases of cardiovascular mortality with a median follow-up of 12.2 years. Consuming at least one glass (250 ml) of SB per day (RR: 1.06; 95% CI: 1.00-1.12, P < 0.001) or ≥2 glasses per day (RR: 1.24; 95% CI: 1.16-1.31, P < 0.001) was significantly associated with increased risk of cardiovascular mortality. SSB and ASB intake of ≥2 glasses per day increased the risk of cardiovascular mortality by 21% (RR:1.21, 95% CI: 1.09-1.33, P < 0.001) and 33% (RR: 1.33, 95% CI: 1.12-1.55, P < 0.001), respectively. CONCLUSIONS: Our findings reveal that high SSB and ASB consumption are associated with an increased risk of cardiovascular mortality. Policymakers and public health practitioners should work on multisectoral strategies to reduce the consumption of sweetened beverages around the world and among all population groups.

RESUMO

BACKGROUND: Existing literature suggests that frequent consumption of sugar-sweetened drinks may be associated with lower semen quality. Studies performed in mice suggest a dose-response relationship between intake of saccharin or aspartame, two artificial sweeteners, and sperm and testis function. METHODS: A cross-sectional study based on data from The Fetal Programming of Semen Quality (FEPOS) Cohort, including 1047 young men (mean age = 19 years) was performed. Each male participant completed an online questionnaire on health, health behavior and diet, and provided a semen sample. The associations between consumption of sugar-sweetened or artificially sweetened beverages (moderate ≥ 3 days/week; infrequent < 3 days/week) and semen quality were analyzed using a multivariable, negative, binomial regression model. RESULTS: Sugar-sweetened or artificially sweetened beverage consumption was not strongly associated with either semen volume, sperm concentration, total sperm count or total motility in young men. The proportion of morphologically normal sperm was 11% lower (0.89 (95% CI 0.76, 1.04)) for moderate (≥3 days/week) consumption of artificially sweetened beverages relative to infrequent (<3 days/week). CONCLUSION: Consumption of sugar-sweetened or artificially sweetened beverages, at the levels present in this study had limited effect on the measured markers of semen quality in young men.

RESUMO

BACKGROUND: In recent years, the consumption of sugar sweetened beverages has been declining, while low calorie sweetener and diet beverage consumption is increasing. Evidence about the effect of diet drinks on dental caries is insufficient, and has not accounted for the complexity of beverage consumption patterns. Therefore, the aim of this study is to examine the association between consuming diet drinks and dental caries among US adults. METHODS: We analyzed 2011-2014 NHANES dietary data of adults using cluster analysis, with individuals grouped based on their beverage consumption. Clusters were identified based on the R-square statistic and the local peak of the pseudo F statistic. Survey procedure and sample weights were used to account for the complex NHANES sampling design. RESULTS: Four beverage consumption patterns were identified: "high soda", "high diet drinks", "high coffee/tea" and "high water". The "High soda" cluster was the only one associated with higher DMFT after controlling for confounders (ß=1.02, 95% CI=0.42 - 1.63), whereas DT was associated with "high soda" (ß=0.45, 95% CI=0.25 - 0.64) and "high coffee/tea" (ß=0.24, 95% CI=0.01 - 0.47). On the other hand, the "high diet drinks" cluster was neither associated with DMFT (ß=0.69, 95% CI=0.51 - -0.35) nor DT (ß=0.07, 95% CI=-0.21 - 0.35). CONCLUSION: Diet drinks consumption may not be associated with increased risk of dental caries. However, more studies should be conducted in order to confirm this finding.

RESUMO

Effective strategies to reduce free sugar intake are needed. This study examined exposure to a warning label, independently and in conjunction with a Health Star Rating (HSR) label, on the selection of commercially available cold beverages with real decision-making stakes. Participants (N = 511, 47.9% female, mean = 21.7 (SD = 6.1) years) accessed an online convenience store app via an on-campus laptop to select one of 10 beverages (5 sugar-sweetened beverages [SSBs], 1100% fruit juice, 2 artificially sweetened beverages [ASBs] and 2 waters). The task was repeated with the addition of a warning label on high-sugar drinks in Round 2, and the addition of an HSR label on all drinks in Round 3. Participants were informed that they would receive a complementary drink (valued at <$5AUD) based on their selections following the completion of a brief questionnaire. Baseline results indicated that SSBs and waters were the most and least popular choices, respectively. For both males and females, there was a significant decrease in SSB selection (p < 0.001) and significant increase in ASB and water selection (p < 0.001) following the addition of warning labels to high-sugar drinks. The decreased selection of SSBs and increased selection of waters was maintained in Round 3 when HSR labels were added to all drinks. 100% fruit juice selection decreased with the addition of a warning label for females only (p < 0.01), but increased following the addition of a 4-star HSR label, for both males (p < 0.05) and females (p < 0.001). Warning labels reduced young adults' selection of SSBs and promoted substitution to water. The HSR reinforced this effect for the least healthy drinks. Increased water selection may be further enhanced by ensuring that warning label thresholds and HSR algorithms align to present consistent messaging.

RESUMO

Objective: Using Meta-analysis to evaluate the relation of sugar-sweetened beverages (SSBs) intakes and artificially sweetened beverages (ASBs) intakes with risk of incident cardiovascular disease. Methods: "Sugar-sweetened beverages"(SSBs),"artificially sweetened beverages"(ASBs),"coronary heart disease"(CHD),"stroke","cardiovascular disease"(CVD), and related terms (both in English and in Chinese) were searched in Pubmed, EMBASE, Web of Science, Cochrane library, ProQuest, China National Knowledge Infrastructure (CNKI), Wanfang databases, and VIP Chinese Science and Technology Journal. Besides, it searched for additional references in websites including Clinical Tirals.gov and International Clinical Trials Registry Platform. The time was up to May 31st 2020. Stata 13 software was used to calculate pooled RR, perform heterogeneity test, and assess publication bias. Results: A total of 14 articles were included from the 40 804 articles retrieved, including 12 articles from European and American countries and 2 articles from Asian countries. The baseline mean age of the participants ranged from 52 to 69 years, and the mean follow-up time was from 6 to 26 years. Meta-analysis showed that compared with those in the lowest group, the RR (95%CI) for those in the highest group of SSBs consumption was 1.11 (1.04-1.08) for CHD, 1.10 (1.01-1.19) for stroke, and 1.09 (0.96-1.24) for CVD events. The corresponding RR (95%CI) comparing extreme groups of ASBs consumption was 1.10 (0.98-1.23) for CHD, 1.19 (1.09-1.29) for stroke, and 1.32 (1.15-1.52) for CVD events. Further analysis for subtypes of stroke showed that compared with the lowest group, the RR (95%CI) for those in the highest groups of SSBs consumption was 1.10 (0.99-1.22) for ischemic stroke and 0.86 (0.71-1.04) for hemorrhagic stroke. The corresponding RR (95%CI) comparing extreme consumption of ASBs was 1.23 (1.04-1.46) for ischemic stroke and 1.33 (1.03-1.72) for hemorrhagic stroke. Conclusion: Higher consumption of SSBs or ASBs may lead to increased risk of incident CHD and stroke (particularly ischemic stroke).

RESUMO

Objectives. To assess the effect of a 2017 excise tax on sugar and artificially sweetened beverages in Philadelphia, Pennsylvania, on the shopping patterns of low-income populations using Supplemental Nutrition Assistance Program (SNAP) data. Methods. I used a synthetic controls approach to estimate the effect of the tax on Philadelphia and neighboring Pennsylvania counties (Bucks, Delaware, and Montgomery) as measured by total SNAP sales ("SNAP redemption") and SNAP redemption per SNAP participant. I assembled biannual data (2005-2019) from all US counties for SNAP redemption and relevant predictors. I performed placebo tests to estimate statistically significant effects and conducted robustness checks. Results. Detectable increases in SNAP spending occurred in all 3 Philadelphia neighboring counties. Per-participant SNAP spending increased in 2 of the neighboring counties and decreased in Philadelphia. These effects were robust across multiple specifications and placebo tests. Conclusions. The tax contributed to increased SNAP shopping in Philadelphia's neighboring counties across both outcome measures, and decreased spending in Philadelphia (at least by 1 measure). This raises questions about retailer behavior, the effectiveness of the tax's public health aim of reducing sugar-sweetened beverage consumption, and policy aims of investing in low-income communities.

RESUMO

Consumption of diet beverages (DB) containing low-calorie sweeteners (LCS) is widespread in the United States. LCS are ingested by nursing infants upon maternal DB consumption, which may impact infants' weight and health. This study aims to examine cross-sectional associations between infants' LCS exposure via maternal DB intake during lactation and infants' health outcomes. Six hundred and eighty-two mother-infant dyads at three months postpartum, from the Infant Feeding Practices Study II, 2005-2007, were included in the analysis. Maternal DB consumption during lactation was estimated using the serving size and frequency of DB consumption reported on the diet history questionnaire. Infants' LCS exposure was estimated by multiplying maternal DB consumption and breastfeeding intensity. Infant outcomes included weight, weight-for-age and BMI-for-age z-scores, overweight, and gastrointestinal (GI) symptoms including diarrhea, reflux, and vomiting. Associations between infants' LCS exposure and continuous and categorical outcomes were examined using linear and logistic regressions adjusting for confounders, respectively. Forty-three percent of lactating women reported DB consumption. While no significant associations were observed between infants' LCS exposure and BMI-for-age or risk of overweight, infants' LCS exposure was associated with a 2.78-fold increased risk of vomiting (95% confidence interval 1.05-7.34). Potential adverse effects of LCS exposure on GI symptoms require further study, and null findings on infant weight should be interpreted with caution, given the small sample size. Additional research is needed to inform recommendations for or against DB consumption during lactation.

RESUMO

Although studies have examined the association between habitual consumption of sugar- (SSBs) and artificially sweetened beverages (ASBs) and health outcomes, the results are inconclusive. Here, we conducted a dose-response meta-analysis of prospective cohort studies in order to summarize the relationship between SSBs and ASBs consumption and risk of type 2 diabetes (T2D), cardiovascular diseases (CVDs), and all-cause mortality. All relevant articles were systematically searched in PubMed, Embase, and Ovid databases until 20 June 2020. Thirty-four studies met the inclusion criteria and were eligible for analysis. Summary relative risks (RRs) and 95% confidence intervals (95% CI) were estimated using random effects or fixed-effects model for highest versus lowest intake categories, as well as for linear and non-linear relationships. With each additional SSB and ASB serving per day, the risk increased by 27% (RR: 1.27, 95%CI: 1.15-1.41, I2 = 80.8%) and 13% (95%CI: 1.03-1.25, I2 = 78.7%) for T2D, 9% (RR: 1.09, 95%CI: 1.07-1.12, I2 = 42.7%) and 8% (RR: 1.08, 95%CI: 1.04-1.11, I2 = 45.5%) for CVDs, and 10% (RR: 1.10, 95%CI: 0.97-1.26, I2 = 86.3%) and 7% (RR: 1.07, 95%CI: 0.91-1.25, I2 = 76.9%) for all-cause mortality. Linear relationships were found for SSBs with T2D and CVDs. Non-linear relationships were found for ASBs with T2D, CVDs, and all-cause mortality and for SSBs with all-cause mortality. The findings from the current meta-analysis indicate that increased consumption of SSBs and ASBs is associated with the risk of T2D, CVDs, and all-cause mortality.

RESUMO

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.

RESUMO

BACKGROUND: The influence of a high sugar diet on colorectal cancer (CRC) survival is unclear. METHODS: Among 1463 stage I-III CRC patients from the Nurses' Health Study and Health Professionals Follow-up Study, we estimated hazard ratios (HRs) and 95% confidence intervals (CIs) for CRC-specific and all-cause mortality in relation to intake of post-diagnosis sugar-sweetened beverages (SSB), artificially sweetened beverages (ASB), fruit juice, fructose and other sugars. RESULTS: Over a median 8.0 years, 781 cases died (173 CRC-specific deaths). Multivariable-adjusted HRs for post-diagnosis intake and CRC-specific mortality were 1.21 (95% CI: 0.87-1.68) per 1 serving SSBs per day (serving/day) and 1.24 (95% CI: 0.95-1.63) per 20 grams fructose per day. Significant positive associations for CRC-specific mortality were primarily observed ≤5 years from diagnosis (HR per 1 serving/day of SSBs = 1.59, 95% CI: 1.06-2.38). Significant inverse associations were observed between ASBs and CRC-specific and all-cause mortality (HR for ≥5 versus <1 serving/week = 0.44, 95% CI: 0.26-0.75 and 0.70, 95% CI: 0.55-0.89, respectively). CONCLUSIONS: Higher post-diagnosis intake of SSBs and sugars may be associated with higher CRC-specific mortality, but only up to 5 years from diagnosis, when more deaths were due to CRC. The inverse association between ASBs and CRC-specific mortality warrants further examination.

RESUMO

BACKGROUND: Whether consumption of sugar-sweetened beverages (SSBs) or artificially sweetened beverages (ASBs) is associated with the risk of breast cancer is of public health interest. OBJECTIVES: We sought to evaluate associations between consumption of SSBs and ASBs and risks of total and subtype-specific breast cancer. METHODS: We followed 82,713 women from the Nurses' Health Study (1980 to 2016) and 93,085 women from the Nurses' Health Study II (1991 to 2017). Cumulatively averaged intakes of SSBs and ASBs from FFQs were tested for associations with incident breast cancer cases and subtypes using Cox regression models. We also evaluated the associations stratified by menopausal status, physical activity, BMI, and alcohol intake. RESULTS: We documented 11,379 breast cancer cases during 4,655,153 person-years of follow-up. Consumption of SSBs or ASBs was not associated with total breast cancer risk: pooled HRs comparing extreme categories (≥1/day compared with <1/month) were 1.03 (95% CI, 0.95-1.12) and 0.96 (95% CI, 0.91-1.02), respectively. We observed a suggestive interaction by BMI using pooled data (P-interaction = 0.08), where a modestly higher risk of breast cancer with each serving per day increment of SSBs was found in lean women (HR, 1.06; 95% CI, 1.01-1.11) but not among overweight or obese women (HR, 1.00; 95% CI, 0.95-1.06). Moreover, in the pooled, fully adjusted analysis, compared to infrequent consumers (<1/month), those who consumed ≥1 serving of ASBs per day had a lower risk of luminal A breast tumors (HR, 0.90; 95% CI, 0.80-1.01; P-trend = 0.02). CONCLUSIONS: Although no significant associations were observed overall, consumption of SSBs was associated with a slightly higher risk of breast cancer among lean women. This finding could have occurred by chance and needs confirmation. Our findings also suggest no substantial increase in the risk of breast cancer with consumption of ASBs.

RESUMO

Phosphodiesterase type 5 (PDE-5) inhibitors are commonly used to treat erectile dysfunction. There is a problem with synthesis and illegal use of a wide range of analogues of the licenced drugs and a simple class-wide analytical method is required. In this work, based on structural modelling, we developed an immunological method using norneovardenafil as a hapten as it contains only the general sub-structure and the common features of sildenafil-like adulterants, such as hydrophobic centres, hydrogen-bond donor atoms and hydrogen-bond acceptor atoms. Thus theoretically it could induce production of antibody which could recognise multiple sildenafil-like adulterants. By immunising rabbits, a group-specific polyclonal antibody was obtained with the desired broad-spectrum molecular recognition performance against sildenafil-like adulterants. Then, an indirect competitive enzyme-linked immunosorbent assay (icELISA) was developed for the detection of sildenafil-like adulterants in herbal spirit drinks. Under the optimised conditions, the icELISA method showed broad linear ranges for acetildenafil, sildenafil and vardenafil respectively of 0.7 to 27.7 µg/kg, 1.0 to 70.7 µg/kg and 1.5 to 22.7 µg/kg, with half-maximal inhibition concentration (IC50) values of 4.5 µg/kg, 8.3 µg/kg and 5.7 µg/kg, respectively. For eleven herbal spirit drinks, there was good agreement between total levels of sildenafil-like adulterants measured by icELISA and levels of each of four individual adulterants determined by LC-MS/MS. In short, the developed icELISA can be employed for rapid and simple screening for adulteration of herbal spirit drinks with sildenafil-like compounds.

RESUMO

BACKGROUND: The activation of insulin pathways is hypothesized to promote tumor growth and worsen breast cancer survival. Sugar-sweetened beverages (SSBs) can lead to a higher risk of insulin resistance and may affect survival. The authors prospectively evaluated the relation of postdiagnostic SSB and artificially sweetened beverage (ASB) consumption with mortality among women with breast cancer. METHODS: In total, 8863 women with stage I through III breast cancer were identified during follow-up of the Nurses' Health Study (NHS; 1980-2010) and Nurses' Health Study II (NHSII; 1991-2011). Women completed a validated food frequency questionnaire every 4 years after diagnosis and were followed until death or the end of follow-up (2014 for the NHS and 2015 for the NHSII). Multivariable Cox proportional hazards regression was used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) of breast cancer-specific and all-cause mortality after adjusting for measures of adiposity and other potential predictors of cancer survival. RESULTS: With a median follow-up of 11.5 years, 2482 deaths were prospectively documented, including 1050 deaths from breast cancer. Compared with women who had no consumption, women who had SSB consumption after diagnosis had higher breast cancer-specific mortality (>1 to 3 servings per week: HR, 1.31 [95% CI, 1.09-1.58]; >3 servings per week: HR, 1.35 [95% CI, 1.12-1.62]; Ptrend = .001) and all-cause mortality (>1 to 3 servings per week: HR, 1.21 [95% CI, 1.07-1.37]; >3 servings per week: HR, 1.28 [95% CI, 1.13-1.45]; Ptrend = .0001). In contrast, ASB consumption was not associated with higher breast cancer-specific or all-cause mortality. Furthermore, replacing 1 serving per day of SSB consumption with 1 serving per day of ASB consumption was not associated with a lower risk of mortality. CONCLUSIONS: Higher postdiagnostic SSB consumption among breast cancer survivors was associated with higher breast cancer-specific mortality and death from all causes.
