Context Reducing dietary advanced glycation end-products (AGEs) may favor diabetes control. Objective Critically analyze studies about the effect of dietary AGEs restriction on inflammation, oxidative stress, and glycemic control in patients with type 2 diabetes mellitus (DM2). Data Source This systematic review was conducted according to PRISMA methodology. The PubMed, Web of Science, LILACS, and Cochrane Library databases were searched, using the terms “type 2 diabetes,” “advanced glycation end products” and “diet.” Data Extraction Seven original studies were included in this review. The duration of the studies ranged from 1 day to 16 weeks. All extracted data were compiled, compared, and critically analyzed. Data Analysis Glycemic variables were considered the primary outcomes. The secondary outcomes were glycation, inflammatory, and oxidative stress markers. Conclusion Although serum insulin, homeostasis model assessment of insulin resistance, and glycated hemoglobin values were lower after the consumption of AGEs restricted diets in most studies, there was a lack of unanimity regarding dietary AGEs’ positive effect on inflammation, oxidative stress, and blood glucose. Systematic Review Registration PROSPERO registration no. CRD42020152640.
Objective: To evaluate the prevalence of ultra-processed food consumption and associated factors among children enrolled in the public school system of the city of Barbacena, Minas Gerais, Brazil. Methods: This is a cross-sectional study conducted with schoolchildren aged 7–9 years, of both sexes, enrolled in state public schools. Food intake was assessed using the Previous Day Food Questionnaire and the level of physical activity by the Previous Day Physical Activity Questionnaire. The listed foods were classified according to the extent and purpose of industrial processing, using the NOVA classification. Pearson’s χ2 test, Fisher’s exact test, χ2 with Yates correction, and Poisson regression were used in the statistical analysis, estimating the crude and adjusted prevalence ratio, with 95% confidence intervals. Results: The prevalence of daily ultra-processed food consumption was 69.6%. After adjusted analyses, the consumption of ultra-processed food was associated with the omission of breakfast, mid-afternoon snack, supper, low physical activity, and consumption of risk foods. On the other hand, consumption of in natura or minimally processed foods was associated with older age, the consumption of lunch, mid-afternoon snack, dinner, and protective foods. Conclusions: There is a high prevalence of ultra-processed foods consumption, associated with unhealthy dietary habits among schoolchildren. This highlights the need for nutritional counseling and educational actions, favoring healthy eating in childhood.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
