Reduction of sugar, salt and fat content in foods over the period 2016-2021 in Spain: the National Food Reformulation Plan.

Population´s dietary intake of saturated fat, sodium, and sugars is higher than the current recommendations in Spain and most European countries. Nationwide food reformulation strategies have the potential to improve nutritional quality; however, evaluations are only available in a few countries and are difficult to compare. This study shows the degree of compliance with the nutrient reduction objectives included in a 4-year (2016-2020) Spanish food reformulation initiative. In 2016, baseline median nutrient content was established for 57 food subcategories. Agreed reduction (%) expressed as the median content to be reached by 2020 was set as the objective. In 2021, Spanish Food Safety and Nutrition Agency (AESAN) collected mandatory nutritional information from 3118 products belonging to the food subcategories included in the PLAN. Median nutrient content was calculated and compared with baseline data established in 2016 and PLAN objectives. Median nutrient content reduction was observed in all food subcategories. Relative reductions (%) ranged from 0.6 to 60% for added sugars, 4.8 to 33.3% for salt, 4.5 to 78.3% for saturated fat, and 24.9 to 36% for total fat. PLAN objectives were achieved in all subcategories except for one. The number of products involved, belonging to the highly consumed food categories, shows the potential of national reformulation strategies to improve the nutritional quality of the diet. Compliance with nutrient reduction agreements was 99%; however, the variability of nutrient content within subcategories shows that there is room for further reduction in selected nutrients and food subcategories.

Dietary Sugar Intake Associated with a Higher Risk of Dementia in Community-Dwelling Older Adults.

We have limited evidence for the relationship of high sugar intake with dementia risk. To determine whether high sugar intake is associated with an increased risk of dementia in community-dwelling older adultsMethods:This study included 789 participants of the Rush Memory and Aging Project (community-based longitudinal cohort study of older adults free of known dementia at enrollment), with annual clinical assessments and complete nutrient data (obtained by validated food frequency questionnaire). Clinical diagnosis of dementia is based on the criteria of the joint working group of the National Institute of Neurological and Communicative Disorders and Stroke and the Alzheimer's Disease and Related Disorders Association. We used Cox proportional hazard models. 118 participants developed dementia during 7.3±3.8 years of follow-up. Those in the highest quintile of total sugar intake were twice as likely to develop dementia than those in the lowest quintile (Q5 versus Q1:HR=2.10 (95% CI: 1.05, 4.19) when adjusted for age, sex, education, APOEɛ4 allele, calories from sources other than sugar, physical activity, and diet score. Higher percent calories from sugar were positively associated with dementia risk (β=0.042, p = 0.0009). In exploratory analyses, the highest versus lowest quintile of fructose and sucrose in the diet had higher dementia risk by 2.8 (95% CI: 1.38, 5.67) and 1.93 (95% CI: 1.05, 3.54) times, respectively. A higher intake of total sugar or total calories from sugar is associated with increased dementia risk in older adults. Among simple sugars, fructose (e.g., sweetened beverages, snacks, packaged desserts) and sucrose (table sugar in juices, desserts, candies, and commercial cereals) are associated with higher dementia risk.

Dietary Sugar Research in Preschoolers: Methodological, Genetic, and Cardiometabolic Considerations.

Excess dietary sugar intake increases the risk of unhealthy weight gain, an important cardiometabolic risk factor in children. To further our understanding of this relationship, we performed a narrative review using two approaches. First, research examining dietary sugar intake, its associations with cardiometabolic health, impact of genetics on sweet taste perception and intake, and how genetics moderates the association of dietary sugar intake and cardiometabolic risk factors in preschool-aged children 1.5-5 years old is reviewed. Second, methodological considerations for collecting and analyzing dietary intake of sugar, genetic information, and markers of cardiometabolic health among young children are provided. Our key recommendations include the following for researchers: (1) Further longitudinal research on sugar intake and cardiometabolic risk factors is warranted to inform policy decisions and guidelines for healthy eating in preschool-aged children. (2) Consistency in sugar definitions is needed across research studies to aid with comparisons of results. (3) Select dietary collection tools specific to each study's aim and sugar definition(s). (4) Limit subjectivity of dietary assessment tools as this impacts interpretation of study results. (5) Choose non-invasive biomarkers of cardiometabolic disease until the strengths and limitations of available biomarkers in preschool-aged children are clarified. (6) Select approaches that account for the polygenic nature of cardiometabolic disease such as genome risk scores and genome wide association studies to assess how genetics moderates the relationship between dietary sugar intake and cardiometabolic risk. This review highlights potential recommendations that will support a research environment to help inform policy decisions and healthy eating policies to reduce cardiometabolic risk in young children.

The mediating role of obesity on the prospective association between urinary sucrose and diabetes incidence in a sub-cohort of the EPIC-Norfolk

Background/objectivesFindings from epidemiological studies showed controversial findings between dietary sugar intake and the development of diabetes. Most of these studies assessed dietary sugar intake by self-reports which might be prone to bias. Urinary sucrose, an objective biomarker of sucrose intake, might provide better insights into this association. Thus, the aim of this study was to investigate the associations between sucrose intake, measured via self-reports and urinary sucrose, with incident diabetes and to detect the impact of obesity on this association.Subjects/methodsData of a sub-group (n = 2996) from the prospective EPIC-Norfolk cohort were investigated. Sucrose intake was assessed by self-reports (validated food frequency questionnaire (FFQ) and 7-day diet diaries (7DD)) and as an objective urinary sucrose biomarker. Cox proportional hazard models were conducted to calculate hazard ratios (HRs) and 95% confidence intervals (CI) for the associations between urinary and dietary sucrose intake and incident diabetes. Mediation analysis was performed to investigate the mediated percentage of body mass index (BMI) and waist circumference (WC) on this association.ResultsThe mean age of the participants was 60.6 ± 9.5 years and 53% were women. After a mean follow-up of 11.2 ± 2.9 years, 97 participants developed diabetes. Findings suggested inverse associations regarding incident diabetes for self-reported sucrose intake per 50 g/d via 7DD [HR: 0.63 (95% CI: 0.43, 0.91)], and a tendency via FFQ [HR: 0.81 (95% CI: 0.46, 1.42)]. Urinary sucrose indicated a positive association with incident diabetes for each increase of 100 µM [HR: 1.14 (95% CI: 0.95, 1.36)]. The proportion mediated of BMI and WC for this association was 16 and 22%.ConclusionsThese findings indicate that sucrose measured as objective urinary biomarker points to a positive association with incident diabetes. BMI might partly mediate this association. However, to obtain more precise results, more studies are warranted that consider this objective biomarker.

The Association between Dietary Sugar Intake and Nephrolithiasis: Results from National Health and Nutrition Examination Survey 2007–2018

BackgroundDietary sugar intake is gradually considered a risk factor for many diseases. A sugary diet was positively associated with risk of nephrolithiasis, but the specific relationships remain undefined. ObjectivesTo determine associations between risk of nephrolithiasis and dietary sugar intake. MethodsThis cross-sectional study involved 21,590 participants based on the National Health and Nutrition Examination Survey from 2007 to 2018. Amounts of dietary sugar intake (g/d) were the main exposure, including total sugar intake, added sugar intake, and food sources. Associations were analyzed by logistic regression models and restricted cubic splines using complex weighted designs. ResultsWeighted mean intake [standard error] of total sugar and added sugar were 111.2 [2.0] g/d and 73.7 [1.9] g/d in participants with nephrolithiasis, respectively. In the fully adjusted regression model, compared to those in quartile 1, the population in quartile 4 of total sugar intake showed a significant risk of nephrolithiasis [odds ratio (OR): 1.23; 95% confidence interval (CI): 1.00–1.51]; OR for added sugar intake was 1.56 (95% CI: 1.25–1.94). The risks of nephrolithiasis increased steadily when total sugar and added sugar intake exceeded ∼150 g/d and 63 g/d in restricted cubic spline analyses, respectively. The highest sugar intake from beverages was associated with an increased risk of nephrolithiasis (OR for total sugar: 1.36; 95% CI: 1.07–1.72; OR for added sugar: 1.37; 95% CI: 1.09–1.73). Added sugar intake from meat, egg, and oil was significantly associated with risk of nephrolithiasis (quartile 4, OR: 1.22; 95% CI: 1.02–1.47), whereas total sugar intake from dairy products was in reverse (quartile 4, OR: 0.67; 95% CI: 0.54–0.82). ConclusionsTotal and added sugar intake, sugar intake from beverages, and added sugar intake from meat, egg, and oil were associated with an increased risk of nephrolithiasis, whereas total sugar intake from dairy products was negatively associated.

Adequacy of Nutrient Intake and Malnutrition Risk in Older Adults: Findings from the Diet and Healthy Aging Cohort Study.

There is a lack of data on the adequacy of nutrient intake and prevalence of malnutrition risk in Asian populations. The aim was to report on the nutrient intake and prevalence of malnutrition risk in a community sample of older adults in Singapore. Analysis was performed on 738 (n = 206 male, n = 532 male, aged 67.6 ± 6.0 years) adults 60 years and above. Intakes of macro- and micronutrients were evaluated against the Recommended Dietary Allowances (RDAs). Malnutrition risk was assessed using the Nutrition Screening Initiative Determine Your Nutritional Health checklist. It was found that 90.5% older adults exceeded the sugar intake, 68.5% males and 57.1% females exceeded the intake limit for saturated fat, and 33% males had inadequate dietary fiber intake when compared to the RDAs. Inadequate dietary calcium intake was found in 49.5% males and 55.3% females. There were 22.3% of older adults at moderate to high malnutrition risk. Singaporean older adults need to reduce their dietary intakes of sugar and saturated fat and increase their intakes in dietary fiber and calcium. Current findings provide public health awareness on the importance of healthy eating and will facilitate decision making by health promotors to deliver targeted nutrition care programs.

Rejection thresholds for sweetness reduction in a model drink predict dietary sugar intake

Links between individual sweetness perception and sugar intake have been previously explored, with highly contrasting results. The current study aims to test individual-based rejection thresholds (RjTs) to ascending and descending sucrose concentrations in a model drink, and to evaluate potential links between these measures and sugar intake behaviour in real life. Sixty-three participants (final N = 43 [f = 29]; 20 ± 5 years) each undertook three sensory testing sessions and completed a 4-day weighed food records. Each individual was tested for their Sweet Liker status, detection thresholds to sucrose, RjTs to 5 descending and 5 ascending sucrose concentrations in an orange-flavoured drink, as well as sugar intake in daily diet and from sweetened beverages. The results demonstrate that RjTs can be estimated an individual level. With each participant completing 4 replications of the RjT task, data from over 88% of participants produced a reasonable individual-based psychometric function. Intriguingly, descending, but not ascending, RjTs were positively correlated with sweet liking (r = 0.43, p < 0.01), and acted as a significant predictor of both overall dietary sugar intakes (R2 = 0.10, F(4,38) = 2.23, p = 0.050) and sugar intakes from sweetened beverages (R2 = 0.21, F(4,38) = 3.73, p = 0.012). While sweet likers (SL) and dislikers (SD) had comparable ascending RjTs (acceptance for sugar addition), they differed substantially in terms of descending RjTs (p = 0.002; acceptance for sugar reduction), with SL rejecting samples having > 47% sugar reduction (47 g/L), whereas SD rejecting samples with > 68% reduction (28 g/L). Overall, these findings suggest that descending RjTs is a useful measure for detecting a sensory-diet relationship, and should be considered to better inform sugar reduction targets and facilitate policies on product reformulation.

Design and methods of the German monitoring of packaged food in the European context

Reformulation strategies to reduce the energy, salt, sugar, total fat, and saturated fat content of packaged food are one means to improve the food offer and facilitate healthier food choices. In Germany, the “National Reduction and Innovation Strategy for Sugar, Fats, and Salt”, which runs from 2019 to 2025, is guided by a yearly product monitoring of packaged food. The product monitoring focuses on food categories with a major contribution to dietary intake of sugar, total and saturated fat, and salt, and on products targeted at children. Nutrition labelling information taken from manufacturer's websites serves as the primary data source and is collected manually. Analyses include the current energy, salt, sugar, total fat, and saturated fat content as well as changes of energy and nutrient content over time on the level of food categories and subcategories. Monitoring results are presented on a yearly basis for the comprehensive product range and, for selected product categories, for top-selling products. Differences in data collection and evaluation methods and limited information about the approaches taken by others hamper the comparison with further national monitoring approaches in Europe. Ongoing research projects related to the German monitoring of packaged food seek to a) automate the German data collection and b) harmonize the monitoring across Europe.

P02-009-23 Dietary Sugar Intake and Diet Quality: A Scoping Review

P02-009-23 Dietary Sugar Intake and Diet Quality: A Scoping Review

Gut microbiomes of captive primates show phylosymbiosis, respond to dietary sugar reduction, and select for host-specific dietary microbes.

Host-associated microbiomes are influenced by evolutionary history and proximate factors such as diet and environment. Zoos house animals in relatively standardized and manipulatable environments, making zoo populations valuable for studying microbiomes. Using a small population of five, closely related primate species housed under nearly identical environments, we investigated gut microbiome variation regarding (a) congruence between host evolutionary history and gut bacterial composition (i.e. phylosymbiosis), (b) a longitudinal reduction in dietary sugar intake, and (c) ingestion of bacteria from dietary sources. We found that the primate gut microbiomes varied across individuals and showed phylosymbiosis. When animals were fed diets with reduced sugar and increased fibre, we found host-specific changes in taxonomically distinct microbes (Phascolarctobacterium, Megasphaera, and Sharpea). Yet, these bacterial genera share similar functional potential (fibre degradation), indicating that the distinct bacterial communities may fulfill similar functions. Although all individuals received the same diet, the diet-associated bacteria in primate gut microbiomes were distinct across individuals of different species, suggesting a mechanism that selects for unique dietary microbes to persist in animal guts. Our findings show that the microbiomes of a small, captive primate population housed under uniform environmental conditions still show patterns congruent with combined influences of evolutionary history and diet.

The Dietary Sugars Intake: The Role In Alzheimer’s Disease Pathomechanism

Alzheimer’s disease is a common neurodegenerative disease that affect elderly and it became a serious global burden for years. Despite many studies have been performed, an effective cure for Alzheimer’s was still not be found. Therefore, it is necessary to not only focus on curative methods but also preventive methods with modifiable risk factors and underlying disease, for example lifestyle and metabolic disease, as potential approach in Alzheimer’s disease prevention in the future. The excessive dietary sugar intake has been suggested as a risk factor of many diseases such as metabolic disease and cognitive impairment disease. It may promote cognitive declines through some pathways such as induce alteration of gut microbiomes, metabolism and immune system. These abnormal processes may evoke amyloid β plaque formation and neurofibrillary tangles in brain cells as the effect of chronic inflammation. Chronic inflammation has been widely studied as the hallmark of Alzheimer’s disease pathology. Therefore, the correlation between dietary sugar and impairment cognitive, specifically Alzheimer’s disease will be summarized.

Estimation method and research of fruit glycemic load index based on the fusion SE module Faster R-CNN

In recent years, with the close connection between the field of artificial intelligence and life, people's quality of life has been improved, and food choices have increased. However, how to understand one's own dietary structure and sugar intake and obtain the correct glycemic load index reference has become a more concerned issue for diabetic patients. This paper studies how to measure the dietary intake of diabetic patients. Our purpose is to identify fruits with high sweetness and low glycemic load value, to help diabetic patients give correct and reasonable reference to their daily diet. For better research, we constructed a fruit dataset for studying the daily diet of diabetic patients. At the same time, we improve the Faster R-CNN network for fruit recognition, introduce an attention mechanism module in the feature extraction stage, adjust the anchor aspect ratio of the Region Proposal Network (RPN), and perform a fusion update operation in the fully connected layer. Experiments show that, compared with existing methods, our method im-proves the precision and average recall rate by 2.47% and 3.06%, respectively. Then we designed a volume estimation method, and then obtained the glycemic load index of the fruit, and finally gave an eating opinion based on this value.

A Low Daily Intake of Simple Sugars in the Diet Is Associated with Improved Liver Function in Cirrhotic Liver Transplant Candidates.

(1) Background: We investigated, for the first time, whether dietary simple sugar intake affects MELD score changes over time in a cohort of cirrhotic liver transplant candidates. (2) Methods: the MELD score, dietary habits using a 3-day food diary, and visceral adipose tissue index (VATI) measured with CT scan were assessed in 80 consecutive outpatient cirrhotic patients at baseline, after counseling to follow current nutritional guidelines. The MELD score was reassessed after six months and the DELTA-MELD was calculated as the MELD at the second assessment minus the MELD at baseline. (3) Results: Compared with the baseline, the MELD score of cirrhotic patients at the end of the study was decreased, stable, or increased in 36%, 8% and 56% of patients, respectively. In separate multiple linear regression models, DELTA-MELD was positively and independently correlated with the daily intake of simple sugars expressed in g/kg body weight (p = 0.01) or as a percentage of total caloric intake (p = 0.0004) and with the number of daily portions of fruit, added sugar, jam, and honey (p = 0.003). These associations were present almost exclusively in patients with VATI above the median value. (4) Conclusions: In cirrhotic patients with high amounts of visceral adipose tissue the consumption of simple sugars and fructose should be limited to improve their clinical outcome.

Sugar Consumption Pattern among Cardiometabolic Risk Individuals: A Scoping Review.

The global prevalence of noncommunicable diseases has risen rapidly over the past decade. Research has focused on dietary management, particularly dietary sugar, to prevent and treat noncommunicable diseases. This study undertakes a scoping review of research on the impacts of dietary sugar on cardiometabolic related health outcomes. Ovid Medline, Scopus and Web of Science Core collection databases were used to identify papers published from January 1, 2010 onwards. The included studies had to be cross-sectional or cohort studies, peered review, published in English and in adults, aged 18 years old and above. Articles had to determine the impacts of sugar intake on cardiometabolic related health outcomes. Study quality was measured using the Quality Assessment Tool for Observational Cohort and Cross-sectional Studies. In addition, a narrative synthesis of extracted information was conducted. Thirty-one articles were included in this review. All studies had a large sample size, and the exposure measure was clearly defined, valid and applied consistently across all study participants. Exposure was measured using validated questionnaires. All data were statistically analysed and adjusted for critical potential confounding variables. Results showed that dietary sugar intake was significantly associated with metabolic syndrome, blood pressure, blood glucose, blood lipids, and body weight. Dietary sugar intake significantly increased cardiometabolic risks through mechanisms dependent and independent of weight gain. It is essential to create public awareness on the topics of cardiometabolic risk management and dietary sugars intake.

Real-World Intake of Dietary Sugars Is Associated with Reduced Cortisol Reactivity Following an Acute Physiological Stressor.

There is increasing academic and clinical interest in understanding the nature of the relation between diet and response to stress exposure as a risk factor for mental illness. Cross-species evidence shows that conditions of chronic and acute stress increase the intake of, and preference for, caloric-dense palatable foods, a phenomenon thought to be explained by the mitigating effects of comfort foods on the activity of the stress-response network. It is largely unknown whether and how real-world dietary intake of saturated fat and sugars impacts stress responsivity in humans. Therefore, here we examined whether real-world dietary intake of saturated fat and sugars predicted salivary cortisol reactivity following an acute physiological stressor. Multilevel modelling of four salivary cortisol measures collected up to 65 min after the stressor on 54 participants (18-49 years old) were analyzed using a quadratic growth curve model. Sugar intake significantly predicted a weaker cortisol response following the Cold Pressor Test (CPT) controlling for BMI and gender, revealing an inhibitory effect of caloric-dense diets on cortisol reactivity to stress. As the consumption of sugar rose individuals had lower post-stressor cortisol levels, a smaller rate of increase in cortisol 20 and 35 min after the CPT, a lower cortisol peak, and an overall weaker quadratic effect. These observations add to a growing body of evidence reporting suppressive effects of high-energy foods on stress-associated glucocorticoids reactivity and are consistent with the comfort food hypothesis, where people are seen as motivated to eat palatable foods to alleviate the detrimental repercussions of stressor exposure.

Aspalathin and Other Rooibos Flavonoids Trapped α-Dicarbonyls and Inhibited Formation of Advanced Glycation End Products In Vitro

The excessive dietary intake of simple sugars and abnormal metabolism in certain diseases contribute to the increased production of α-dicarbonyls (α-DCs), such as methylglyoxal (MGO) and glyoxal (GO), the main precursors of the formation of advanced glycation end products (AGEs). AGEs play a vital role, for example, in the development of cardiovascular diseases and diabetes. Aspalathus linearis (Burman f.) R. Dahlgren (known as rooibos tea) exhibits a wide range of activities beneficial for cardio-metabolic health. Thus, the present study aims to investigate unfermented and fermented rooibos extracts and their constituents for the ability to trap MGO and GO. The individual compounds identified in extracts were tested for the capability to inhibit AGEs (with MGO or GO as a glycation agent). Ultra-high-performance liquid chromatography coupled with an electrospray ionization mass spectrometer (UHPLC-ESI-MS) was used to investigate α-DCs' trapping capacities. To evaluate the antiglycation activity, fluorescence measurement was used. The extract from the unfermented rooibos showed a higher ability to capture MGO/GO and inhibit AGE formation than did the extract from fermented rooibos, and this effect was attributed to a higher content of dihydrochalcones. The compounds detected in the extracts, such as aspalathin, nothofagin, vitexin, isovitexin, and eriodictyol, as well as structurally related phloretin and phloroglucinol (formed by the biotransformation of certain flavonoids), trapped MGO, and some also trapped GO. AGE formation was inhibited the most by isovitexin. However, it was the high content of aspalathin and its higher efficiency than that of metformin that determined the antiglycation and trapping properties of green rooibos. Therefore, A. linearis, in addition to other health benefits, could potentially be used as an α-DC trapping agent and AGE inhibitor.

Just noticeable difference in sweetness perception of cola: Small changes in sugar are noticeable.

These data could help researchers and industry product developers know how much sugar can be reduced from a cola-flavored beverage before the change is apparent to consumers.

Excessive sucrose exacerbates high fat diet-induced hepatic inflammation and fibrosis promoting osteoarthritis in mice model

Osteoarthritis (OA) is marked by chronic low-grade systemic inflammation and cartilage destruction. High fat diet causes obesity and increases the risk of knee OA-development. However, the impact of high dietary sugar intake on OA pathogenesis has not been elucidated yet. Therefore, we investigated the effects of a high-fat and high-sucrose (HF+HS) diet in experimental OA mouse models. Eight-week-old male C57BL/6J mice were fed a standard chow (n=6), high-fat (HF) (n=5), or HF+HS (n=7) diets for 12 weeks; thereafter, the mice underwent surgical destabilization of the medial meniscus (DMM) and received the same experimental diets for an additional 8 weeks. The pathogenesis of knee OA, obesogenic parameters, and inflammation levels in the liver and adipose tissue were investigated. HF+HS diet induced severe cartilage erosion with osteophyte development and subchondral bone plate thickening, indicating that HF+HS diet exacerbated OA. Despite marginal differences in metabolic parameters, hepatic free cholesterol accumulation increased in mice with DMM-induced OA fed on HF+HS diet than in those fed HF diet. Notably, the levels of inflammatory cytokines and fibrosis markers were greater in the livers of mice with DMM-induced OA, fed on HF+HS diet than those in the control group. However, adipose tissue remodeling was not affected by the HF+HS diet. These findings indicate that excess sucrose intake along with a HF diet triggers hepatic inflammation and fibrosis, thereby, contributing to OA pathogenesis.

The Bitter Side of Sugar Consumption: A Mitochondrial Perspective on Diabetes Development

Type 2 diabetes (T2D) has increased worldwide at an alarming rate. Metabolic syndrome (MetS) is a major risk factor for T2D development. One of the main reasons for the abrupt rise in MetS incidence, besides a sedentary lifestyle, is the westernized diet consumption, with high content of industrialized foods, rich in added dietary sugars (DS), mainly sucrose and fructose. It has been suggested that a higher intake of DS could impair metabolic function, inducing MetS, and predisposing to T2D. However, it remains poorly explored how excessive DS intake modulates mitochondrial function, a key player in metabolism. This review explores the relationship between increased consumption of DS and mitochondrial dysfunction associated with T2D development, pointing to a contribution of the diet-induced accumulation of advanced glycation end-products (AGEs), with brief insights on the impact of maternal high-sugar diet and AGEs consumption during gestation on offspring increased risk of developing T2D later in life, contributing to perpetuate T2D propagation.

Chronic intake of high dietary sucrose induces sexually dimorphic metabolic adaptations in mouse liver and adipose tissue

Almost all effective treatments for non-alcoholic fatty liver disease (NAFLD) involve reduction of adiposity, which suggests the metabolic axis between liver and adipose tissue is essential to NAFLD development. Since excessive dietary sugar intake may be an initiating factor for NAFLD, we have characterized the metabolic effects of liquid sucrose intake at concentrations relevant to typical human consumption in mice. We report that sucrose intake induces sexually dimorphic effects in liver, adipose tissue, and the microbiome; differences concordant with steatosis severity. We show that when steatosis is decoupled from impairments in insulin responsiveness, sex is a moderating factor that influences sucrose-driven lipid storage and the contribution of de novo fatty acid synthesis to the overall hepatic triglyceride pool. Our findings provide physiologic insight into how sex influences the regulation of adipose-liver crosstalk and highlight the importance of extrahepatic metabolism in the pathogenesis of diet-induced steatosis and NAFLD.
