RESUMO

Diabetes is a non-communicable disease that has reached epidemic proportions, affecting 537 million people globally. Artificial Intelligence can support patients or clinicians in diabetes nutrition therapy - the first medical therapy in most cases of Type 1 and Type 2 diabetes. In particular, ontology-based recommender and decision support systems can deliver a computable representation of experts' knowledge, thus delivering patient-tailored nutritional recommendations or supporting clinical personnel in identifying the most suitable diet. This work proposes a systematic literature review of the domain ontologies describing diabetes in such systems, identifying their underlying conceptualizations, the users targeted by the systems, the type(s) of diabetes tackled, and the nutritional recommendations provided. This review also delves into the structure of the domain ontologies, highlighting several aspects that may hinder (or foster) their adoption in recommender and decision support systems for diabetes nutrition therapy. The results of this review process allow to underline how recommendations are formulated and the role of clinical experts in developing domain ontologies, outlining the research trends characterizing this research area. The results also allow for identifying research directions that can foster a preeminent role for clinical experts and clinical guidelines in a cooperative effort to make ontologies more interoperable - thus enabling them to play a significant role in the decision-making processes about diabetes nutrition therapy.

RESUMO

Diabetes is a disease found in every 1 out of 4 people in the world. The glucose molecule is one of the sources of energy in the body and the lack of the digestion of glucose causes diabetes type 1 and type 2. Arginine and cysteine are nonessential amino acids that contain sulfur and help maintain the metabolisms of humans. We explored the glucose-arginine (Glc-arg) and glucose-cysteine (Glc-cys) molecules by finding their structural properties, electronic properties, chemical reactivity, mechanical strength, and transport properties because these non-essential amino acid molecules inhibit glucose-stimulated insulin secretion. Density functional theory (DFT) has been implemented to study all the properties of Glc-arg and Glc-cys using SIESTA software. Glucose-arginine (Glc-arg) inhibits a large percentage of glucose secretion and shows high chemical reactivity.

RESUMO

Post-transplant diabetes mellitus is associated with long-term immunosuppression and weight gain, and is related to an increased risk of cardiovascular disease, accelerated loss of graft and increased mortality. There is an absence of strong evidence-based dietary guidelines for the prevention and management of post-transplant diabetes mellitus in kidney transplant recipients. The aim of this study was to systematically review all dietary evidence for kidney transplant recipients on clinical outcomes relating to diabetes, patient-reported outcomes and economic outcomes. A comprehensive literature search was conducted in August 2020 using the databases Medline, Embase, CENTRAL and CINAHL. Studies were critically appraised using Cochrane risk of bias tools and GRADE. A total of 12 studies and 1928 participants were included. Four papers focused on diet and exercise, one paper on diet only, two papers on magnesium supplementation, one paper on magnesium and fibre intake, two papers on Mediterranean diet, one paper on marine n-3 fatty acid supplementation and one paper on fruit and vegetable intake. There were no significant effects on outcomes relating to dietary counselling, magnesium supplementation, magnesium and fibre intake or marine n-3 fatty acid supplementation. Low-quality evidence supports the Mediterranean diet in reducing the risk of post-transplant diabetes mellitus and fasting plasma glucose levels. Low-quality evidence suggests vegetable intake being associated with a lower risk of post-transplant diabetes mellitus. This review demonstrates limited evidence for dietary interventions in the prevention and management of diabetes in post-kidney transplantation. The findings suggest that further high-quality research with robust study designs is required.

RESUMO

Nutrition is crucial for maintaining normal growth, development, and glycemic control in young people with diabetes (PwD). Undue restrictions cause nutrient deficiencies as well as poor adherence to meal plans. Widespread availability of low-cost, ultra-processed, and hyperpalatable food is further damaging. Most families struggle to find ways to provide nutritious, yet attractive, food with a low glycemic index (GI). India is one of the oldest continuous civilizations with a rich and diverse cultural and culinary heritage. Traditional dietary practices, including the centuries-old 'Thali' (meaning plate) concept, emphasize combinations (grains, lentils, vegetables, dairy, spices, prebiotics and probiotics, and fats) of local, seasonal, and predominantly plant-based ingredients. These practices ensure that all of the necessary food groups are provided and fit well with current evidence-based recommendations, including the International Society for Pediatric and Adolescent Diabetes (ISPAD) 2018 Guidelines. Techniques for the preparation, cooking, and preservation of food further impact the GI and nutrient availability. These practices benefit nutrient density, diet diversity, and palatability and thus improve adherence to meal plans and glycemic control. This narrative review describes the ancient wisdom, food composition, and culinary practices from across India which are still valuable today. These may be of benefit worldwide to improve glycemic control as well as quality of life, especially in PwD.

RESUMO

Although coffee consumption has been historically associated with negative health outcomes, recent evidence suggests a lower risk of metabolic syndrome, obesity and diabetes among regular coffee drinkers. Among the plethora of minor organic compounds assessed as potential mediators of coffee health benefits, trigonelline and its pyrolysis product N-methylpyridinium (NMP) were preliminary shown to promote glucose uptake and exert anti-adipogenic properties. Against this background, we aimed at characterizing the effects of trigonelline and NMP in inflamed and dysfunctional human adipocytes. Human Simpson-Golabi-Behmel syndrome (SGBS) adipocytes were treated with NMP or, for comparison, trigonelline, for 5 h before stimulation with tumor necrosis factor (TNF)-α. NMP at concentrations as low as 1 µmol/L reduced the stimulated expression of several pro-inflammatory mediators, including C-C Motif chemokine ligand (CCL)-2, C-X-C Motif chemokine ligand (CXCL)-10, and intercellular adhesion Molecule (ICAM)-1, but left the induction of prostaglandin G/H synthase (PTGS)2, interleukin (IL)-1ß, and colony stimulating factor (CSF)1 unaffected. Furthermore, NMP restored the downregulated expression of adiponectin (ADIPOQ). These effects were functionally associated with downregulation of the adhesion of monocytes to inflamed adipocytes. Under the same conditions, NMP also reversed the TNF-α-mediated suppression of insulin-stimulated Ser473 Akt phosphorylation and attenuated the induction of TNF-α-stimulated lipolysis restoring cell fat content. In an attempt to preliminarily explore the underlying mechanisms of its action, we show that NMP restores the expression of the master regulator of adipocyte differentiation peroxisome proliferator-activated receptor (PPAR)γ and downregulates activation of the pro-inflammatory mitogen-activated protein jun N-terminal kinase (JNK). In conclusion, NMP reduces adipose dysfunction in pro-inflammatory activated adipocytes. These data suggest that bioactive NMP in coffee may improve the inflammatory and dysmetabolic milieu associated with obesity.

RESUMO

Diabetes mellitus is a major public health concern associated with high mortality and reduced life expectancy. The alarming rise in the prevalence of diabetes is linked to several factors including sedentary lifestyle and unhealthy diet. Nutritional intervention and increased physical activity could significantly contribute to bringing this under control. Food-derived bioactive peptides and protein hydrolysates have been associated with a number health benefits. Several peptides with antidiabetic potential have been identified that could decrease blood glucose level, improve insulin uptake and inhibit key enzymes involved in the development and progression of diabetes. Dietary proteins, from a wide range of food, are rich sources of antidiabetic peptides. Thus, there are a number of benefits in studying peptides obtained from food sources to develop nutraceuticals. A deeper understanding of the underlying molecular mechanisms of these peptides will assist in the development of new peptide-based therapeutics. Despite this, a comprehensive analysis of the antidiabetic properties of bioactive peptides derived from various food sources is still lacking. Here, we review the recent literature on food-derived bioactive peptides possessing antidiabetic activity. The focus is on the effectiveness of these peptides as evidenced by in vitro and in vivo studies. Finally, we discuss future prospects of peptide-based drugs for the treatment of diabetes.

RESUMO

The Mediterranean diet (MedDiet), one of the most studied and well-known dietary patterns worldwide, has been associated with a wide range of benefits for health. In the present narrative review, we aimed to provide a comprehensive overview of the current knowledge on the relation of the MedDiet to important health outcomes, considering both observational and intervention studies with both risk factors and clinical diseases as outcomes. In addition, we considered the clinical and public health impacts of the MedDiet on both human and planetary health. Earlier research confirmed by recent studies has provided strong evidence for the benefits of the MedDiet on cardiovascular health, including reduction in the incidence of cardiovascular outcomes as well as risk factors including obesity, hypertension, metabolic syndrome, and dyslipidaemia. There is also evidence that MedDiet is associated with lower rates of incident diabetes, and better glycaemic control in diabetic patients compared to control diets. In prospective studies, adherence to the MedDiet reduced mortality, especially cardiovascular mortality, hence increased longevity. In addition, it has been associated with less age-related cognitive dysfunction and lower incidence of neurodegenerative disorders, particularly Alzheimer's disease. Furthermore, the relatively low environmental impacts (water, nitrogen and carbon footprint) of the MedDiet is an additional positive aspect of the Mediterranean dietary model. It is likely that the combination of a healthy diet with social behaviours and the way of life of Mediterranean regions makes the MedDiet a sustainable lifestyle model that could likely be followed in other regions with country-specific and culturally appropriate variations.

RESUMO

Diabetes is a metabolic disorder described as insufficient secretion of insulin in the pancreas or the inability of the existing insulin to function properly. It poses a greater risk on human health as it is considered the base of several diseases. Thus, this study was designed to evaluate two novel strains of Lactobacillus in handling pancreas disorders. 50 BALB/c male mice were divided into five groups; (a) feeding on normal diet only as control group, (b) given 21% fructose in drinking water as diabetes group, (c) feeding on Lactobacillus rhamnosus strain Pro2 (MT505335.1) plus 21% fructose as LR group, (d) feeding on Lactobacillus plantarum strain Pro1 (MT505334.1) plus 21% fructose as LP group and (e) mixture of two strains plus 21% fructose as Mix group. The serum content of glucose, aspartate aminotransferase (AST), and alanine aminotransferase (ALT) was determined. Pancreases histopathology was examined. Expression of GH, IGF1, and GLP-1 genes was measured in the liver and pancreas by RT-qPCR. Serum content of glucose, ALT, and AST significantly increased in diabetes group, and significantly reduced in (LP) and (Mix) groups compared with control. Pathological changes occurred in the exocrine and endocrine components of the diabetes group pancreas. Besides, islet cells are almost entirely disturbed and acinar cells degenerated. However, in (LP) and (Mix) groups, the pathological changes significantly decreased and became related to the control group. Expression of GH, IGF1, and GLP-1 genes was significantly downregulated in the liver and pancreas of mice given fructose compared with control. Expression of these genes was either significantly upregulated in groups (LP and Mix) or identical to the control group. This study shows that the strain Pro1 (MT505334.1) or a combination of two strains is useful in reducing diabetic risk.

RESUMO

Processed and ready-to-eat foods become routinely consumed resulting in a sharp rise of sugar intake in people's daily diets. The inclusion of fresh fruits and vegetables rich in (poly)phenols has been encouraged by the World Health Organization (WHO) as part of the daily choices to ameliorate endothelial dysfunction and ease the socio-economic burden of diabetes. Research in Food, Nutrition, and Cell Metabolism areas is revealing that the health benefits of (poly)phenol-rich foods go beyond their antioxidant properties and are in fact key modulators of redox and glycaemia status, and inflammatory response contributing to improved endothelial function and vascular health in diabetes. Other beneficial aspects include appetite modulation, regulation of hydrolytic enzymes involved in sugar and lipid metabolism, and mediation of cell-cell aggregation events. This work overviews the current knowledge on the biological properties of ingested (poly)phenols in cultured endothelial cells with emphasis on the circulating (poly)phenols, providing support to (poly)phenol-rich diets as alternatives to drug-based therapies in the prevention, treatment, and management of diabetes. A critical evaluation on the caveats and challenges involve in current experimental cell-based designs and approaches adopted is also discussed.

RESUMO

Pergunta: Quais são as estratégias alimentares mais efetivas para o tratamento de pessoas com diabetes mellitus tipo 1 e tipo 2? Métodos: As buscas na literatura foram realizadas em cinco bases de dados, com restrição de ano de publicação (a partir do ano 2010). Foram incluídas revisões sistemáticas em inglês, português e espanhol que avaliaram o efeito de dietas no tratamento da diabetes mellitus na população adulta. Nesta revisão rápida, produzida em dez dias, a seleção dos artigos, a extração dos dados de interesse e avaliação da qualidade metodológica (por meio do instrumento AMSTAR 2) foram realizadas de forma individual e independente, ou seja, sem revisão de um segundo pesquisador. Após a leitura completa, foi aplicada uma nova restrição de data de publicação, considerando estudos a partir de 2015, devido ao grande quantitativo e à exaustão de conteúdos identificada nos artigos. Resultados: Foram incluídas 31 revisões sistemáticas, a maioria com qualidade metodológica criticamente baixa, de acordo com critérios do AMSTAR 2. Oito categorias de estratégias alimentares foram identificadas: Dietas com modificações nos carboidratos; dietas ovo-lacto-vegetarianas, vegetarianas ou veganas; dieta mediterrânea; programas de jejum ou de jejum intermitente; dietas com modificações nas proteínas; planos alimentares específicos; dietas com restrição de energia e dietas com modificações nas gorduras. Considerando os desfechos de interesse, foram avaliadas tanto medidas de glicose e hemoglobina glicada, quanto medidas antropométricas que podem influenciar no tratamento da diabetes. No geral, as dietas foram descritas como efetivas para obter resultados positivos nos desfechos relacionados à diabetes. Conclusão e limitações: Apenas uma revisão sistemática foi considerada de alta confiança. Nela, houve maior redução da hemoglobina glicada entre pessoas com DM2 que realizaram dieta com baixo teor de carboidratos se comparadas às pessoas que fizeram dietas de consumo padrão de carboidrato (diferença média de −1,0 mmol/mol; p=0,0132). No entanto, para o desfecho de perda de peso, a dieta com baixo teor de carboidratos teve resultados insignificantes quando comparada com dietas de restrição de gorduras. Já na única revisão sistemática de qualidade moderada, a dieta com baixo teor de carboidratos teve resultados mistos (em alguns estudos primários foram positivos, em outros a diferença não foi estatisticamente significante) para glicemia de jejum (pacientes com DM1) quando comparada à dieta de alto teor de carboidrato e ao consumo padrão. Os demais estudos secundários incluídos nesta revisão foram avaliados, em sua maioria, como de qualidade criticamente baixa ou baixa. Isso significa que o grau de confiança que pode ser atribuído a esses achados é pequeno, portanto, mais estudos são necessários para afirmar com segurança o efeito das dietas nos desfechos relacionados à diabetes mellitus. Esta revisão rápida possui limitações que precisam ser consideradas na interpretação dos achados, como as restrições relativas à metodologia de sínteses rápidas, com filtros, processos de seleção, extração e critérios de elegibilidade reduzidos. Em relação às limitações dos estudos primários que compõem as revisões sistemáticas incluídas, os autores relataram a existência de grande heterogeneidade entre os estudos primários, baixa qualidade metodológica, pequeno número de participantes, baixa adesão de participantes ou reporte inadequado da adesão, períodos curtos de seguimento dos resultados, entre outras. Por fim, os resultados aqui apresentados fornecem elementos importantes a serem considerados na construção de estratégias alimentares para o tratamento da diabetes. Além das intervenções aqui relatadas, é importante ressaltar a necessidade de adaptação das estratégias nutricionais para as diferentes populações e contextos, bem como o levantamento de possíveis barreiras e facilitadores que podem impactar a adesão a diferentes dietas.

RESUMO

Flavonoids are natural plant-derived dietary bioactive compounds having a substantial impact on human health. Morin hydrate is a bioflavonoid mainly obtained from fruits, stem, and leaves of Moraceae family members' plants. Plenty of evidences supported that morin hydrate exerts its beneficial effects against various chronic and life-threatening degenerative diseases. Our current article discloses the recent advances that have been studied to explore the biological/pharmacological properties and molecular mechanisms to better understand the beneficial and multiple health benefits of morin hydrate. Indeed, Morin hydrate exerts free radical scavenging, antioxidant, anti-inflammatory, anti-cancerous, anti-microbial, antidiabetic, anti-arthritis, cardioprotective, neuroprotective, nephroprotective, and hepatoprotective effects. Moreover, morin hydrate exhibits its pharmacological activities by modulating various cellular signaling pathways such as Nuclear factor kappa-light-chain-enhancer of activated B cells (NF-қB), Mitogen-activated protein kinase (MAPK), Janus kinases/ Signal transducer and activator of transcription proteins (JAKs/STATs), Kelch-like ECH-associated protein1/Nuclear erythroid-2-related factor (Keap1/Nrf2), Endoplasmic reticulum (ER), Mitochondrial-mediated apoptosis, Wnt/ß-catenin, and Mechanistic target of rapamycin (mTOR). Most importantly, morin hydrate has the potential to modulate a variety of biological networks. Therefore, it can be predicted that this therapeutically potent compound could serve as a dietary agent for the expansion of human health and might be helpful for the development of the novel drug in the future. However, due to the lack of clinical trials, special human clinical trials are needed to address the effects of morin hydrate on various life-threatening disparities to recommend morin and/or morin-rich foods with other foods or bioactive dietary components, as well as dose-response interaction and safety profile.

RESUMO

This study was designed to investigate the effects of ultrafine grinding on the physicochemical properties of pea dietary fiber (PDF) and the hypoglycemic effect of ultrafine grinding dietary fiber on diabetes mellitus (DM). So, the PDF was treated by ultrafine grinding technology, and its microstructure and physicochemical properties were determined. Then, the DM model was established, and the 4-week ultrafine grinded pea dietary fiber (UGPDF) diet intervention was conducted by using gavage and feeding. During this period, the blood glucose and body weight of the mice were measured, and an oral glucose tolerance test was measured on the last day. The biochemical blood indexes of the mice were determined, and the pancreas was stained with HE after dissecting. The results showed that after ultrafine grinding, the structure fragmentation, specific surface area increased, and UGPDF showed higher swelling ability as well as water and oil holding capacities. Simultaneously, UGPDF had a significant effect on reducing blood glucose and glycosylated hemoglobin in DM mice, improving the wasting state of mice and increasing the tolerance to glucose. Further, the results of the HE section showed that the pancreatic islet cells gradually returned to normal regular morphology. In biochemical blood indicators, UGPDF reduced TC and TG levels in the blood. This study provided a specific data basis for the following research on the hypoglycemic mechanism, and broadens the application field of PDF. PRACTICAL APPLICATION: The physicochemical properties of pea dietary fiber were improved by ultrafine grinding technology. Because of this, the application of pea dietary fiber in the field of hypoglycemic had a better effect, laying a foundation for the next research on hypoglycemic mechanism.

RESUMO

Although mangiferin has a number of documented beneficial effects, there are no systematic reviews or meta-analyses of its effects in diabetic animal models. To investigate the effects of oral administration of mangiferin on blood glucose levels, body weight, and total cholesterol and triglycerides levels in diabetic animal models, a meta-analysis was conducted and the underlying mechanisms were reviewed. Studies from 6 databases (PubMed, Web of Science, Embase, Cochrane Library, and CNKI (China National Knowledge Infrastructure), and Wanfang Med) were searched from inception to April 2020. After article screening, a total of 19 articles were included in this meta-analysis. The meta-analysis was performed using RevMan 5.3 and STATA 14.0 software. The overall pooled estimate of standardized mean difference (SMD) of mangiferin's effect on blood glucose was -1.27 (95% confidence interval [CI]: -1.71, -0.82, P < .00001). Body weight increased in lean diabetic animals with an SMD of 1.41 (95% CI: 0.57, 2.25; P = .001), while it decreased in obese diabetic animals with an SMD of -0.92 (95% CI: -1.69, -0.14; P = .02). Mangiferin intake reduced serum total cholesterol and triglycerides levels with SMDs of -1.02 (95% CI: -1.43, -0.61; P < .001) and -1.24 (95% CI: -1.70, -0.79; P < .001), respectively. The meta-analysis suggests that oral intake of mangiferin has a significant antidiabetic effect in animal models, and the systematic review suggested that this function might be attributed to its anti-inflammatory and antioxidative properties, as well as to its function of improving glycolipid metabolism and enhancing insulin signaling.

RESUMO

OBJECTIVE: To analyse the influence of the Mediterranean diet (Med Diet) on SLE activity, damage accrual and cardiovascular disease risk markers. METHODS: A cross-sectional study was conducted on 280 patients with SLE [46.9 (12.85) years]. Med Diet adherence was assessed through a 14-item questionnaire on food consumption frequency and habits (total score from 0 to 14 points; higher score is greater adherence to the Med Diet). CRP, homocysteine, SLEDAI-2K (SLE disease activity), and SLICC/ACR and SDI (damage accrual) were measured. Obesity, diabetes mellitus, hypertension and blood lipids, among others, were considered cardiovascular disease risk factors. RESULTS: Greater adherence to the Med Diet was significantly associated with better anthropometric profiles, fewer cardiovascular disease risk factors, and lower disease activity and damage accrual scores (P ≤ 0.001 for SLEDAI and SDI). An inverse relationship between the Med Diet score and SLEDAI (P ≥ 0.001; ß = -0.380), SDI (P ≤ 0.001; ß = -0.740) and hsCRP (P = 0.039; ß = -0.055) was observed. The odds ratio for having active SLE (SLEDAI ≥5) or the presence of damage (SDI ≥1) was lower among patients whose Med Diet score was higher (P ≤ 0.001). Finally, greater consumption of Med Diet foods (olive oil, fruits, vegetables, fish, etc.) and abstaining from red meat and meat products, sugars and pastries was associated with less SLE clinical activity and damage. CONCLUSION: Greater adherence to the Med Diet seems to exert a beneficial effect on disease activity and cardiovascular risk in SLE patients. To confirm these findings, further longitudinal studies would be of interest.

RESUMO

BACKGROUND: Observational studies have indicated beneficial effects of whole grain consumption on human health. However, no evidence based on randomized controlled trials has been established. Our objective was to perform a systematic review and meta-analysis of randomized controlled trials to assess the effects of whole grain consumption in glycaemic control of diabetic patients. METHODS: A comprehensive search in four databases (Web of Science, Pubmed, Scopus and Cochrane library) was conducted to collect potential articles which measured the roles of whole grain consumption on glycaemic control up to October 2021. RESULTS: A total of 16 eligible trials involving 1068 subjects were identified to evaluate the pooled effect. The overall results indicated that compared with the control group, whole grain intake presented a significantly reduced concentration in fast plasma glucose (WMD = -0.51 mmol/L, 95% CI: -0.73, -0.28; I2 = 88.6%, p < 0.001), a homeostasis model assessment of insulin resistance (WMD = -0.39 µU × mol/L2, 95% CI: -0.73, -0.04; I2 = 58.4%, p = 0.014), and glycosylated haemoglobin (WMD = -0.56%, 95% CI: -0.88, -0.25, I2 = 88.5%, p < 0.001), while no significant difference was observed in fast plasma insulin level between groups (SMD = -0.05, 95% CI: -0.25, 0.14; I2 = 40.7%, p = 0.120). In terms of incremental area under the curve (iAUC), data suggested that whole grain effected a significant decrease in Glucose-iAUC (WMD = -233.09 min × mmol/L, 95% CI: -451.62, -14.57; I2 = 96.1%, p < 0.001) and Insulin-iAUC (SMD = -4.80, 95% CI: -8.36, -1.23; I2 = 89.9%, p = 0.002), although only in a small number of studies. Of note, there is evidence for modest unexplained heterogeneity in the present meta-analysis. CONCLUSION: Whole grain consumption confers a beneficial effect on glucose metabolism in patients with diabetes. Regrettably, since relevant studies were scarce, we failed to provide confident evidence of whole grain consumption on acute effects including Glucose-iAUC and Insulin-iAUC, which should be addressed in further trials.

RESUMO

BACKGROUND: Nutritional intervention with the use of phytochemicals is an important method for the treatment and prevention of a metabolic syndrome. The objective of this study was to chemically characterize Moro orange juice. The influence of juice intake on metabolic parameters of rats that were obese, diabetic or both by means of body mass management after the activation of anthocyanins during refrigerated storage was also assessed. RESULTS: Juice intake reversed most of the metabolic abnormalities exhibited by obese rats, including reduction of body mass and improvement of the biochemical profile. The loss of body mass by diabetic animals and obese and diabetic animals was not attributed to juice intake, but to type I diabetes mellitus. In these animals, no improvement was observed in the biochemical profile, liver enzymes and glycemia, so this treatment model was deemed unfeasible. CONCLUSION: The beneficial effects cannot be explained only by the anthocyanin C3G present in the juice, but rather, by the synergism between all the components. Studies in humans are needed to determine whether the ingestion of this orange can be recommended as an effective strategy to prevent or ameliorate complications of obesity. © 2020 Society of Chemical Industry.
