Starch digestibility modulation significantly improves glycemic variability in type 2 diabetic subjects: A pilot study. Nutr Metab Cardiovasc Dis 2021; 31:237-246. [PMID: 32988721 DOI: 10.1016/j.numecd.2020.08.010] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/29/2020] [Revised: 07/31/2020] [Accepted: 08/10/2020] [Indexed: 10/23/2022]
Abstract
BACKGROUND AND AIMS In type 2 diabetes (T2D) patients, the reduction of glycemic variability and postprandial glucose excursions is essential to limit diabetes complications, beyond HbA1c level. This study aimed at determining whether increasing the content of Slowly Digestible Starch (SDS) in T2D patients' diet could reduce postprandial hyperglycemia and glycemic variability compared with a conventional low-SDS diet. METHODS AND RESULTS For this randomized cross-over pilot study, 8 subjects with T2D consumed a controlled diet for one week, containing starchy products high or low in SDS. Glycemic variability parameters were evaluated using a Continuous Glucose Monitoring System. Glycemic variability was significantly lower during High-SDS diet compared to Low-SDS diet for MAGE (Mean Amplitude of Glycemic Excursions, p < 0.01), SD (Standard Deviation, p < 0.05), and CV (Coefficient of Variation, p < 0.01). The TIR (Time In Range) [140-180 mg/dL[ was significantly higher during High-SDS diet (p < 0.0001) whereas TIRs ≥180 mg/dL were significantly lower during High-SDS diet. Post-meals tAUC (total Area Under the Curve) were significantly lower during High-SDS diet. CONCLUSION One week of High-SDS Diet in T2D patients significantly improves glycemic variability and reduces postprandial glycemic excursions. Modulation of starch digestibility in the diet could be used as a simple nutritional tool in T2D patients to improve daily glycemic control. REGISTRATION NUMBER: in clinicaltrials.gov: NCT03289494.

Crescent-Like Lesions as an Early Signature of Nephropathy in a Rat Model of Prediabetes Induced by a Hypercaloric Diet. Nutrients 2020; 12:nu12040881. [PMID: 32218109 PMCID: PMC7230605 DOI: 10.3390/nu12040881] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2020] [Revised: 03/17/2020] [Accepted: 03/22/2020] [Indexed: 02/07/2023] Open
Abstract
Diabetic nephropathy (DN) is a major microvascular complication of diabetes. Obesity and hyperlipidemia, fueled by unhealthy food habits, are risk factors to glomerular filtration rate (GFR) decline and DN progression. Several studies recommend that diabetic patients should be screened early (in prediabetes) for kidney disease, in order to prevent advanced stages, for whom the current interventions are clearly inefficient. This ambition greatly depends on the existence of accurate early biomarkers and novel molecular targets, which only may arise with a more thorough knowledge of disease pathophysiology. We used a rat model of prediabetes induced by 23 weeks of high-sugar/high-fat (HSuHF) diet to characterize the phenotype of early renal dysfunction and injury. When compared with the control animals, HSuHF-treated rats displayed a metabolic phenotype compatible with obese prediabetes, displaying impaired glucose tolerance and insulin sensitivity, along with hypertriglyceridemia, and lipid peroxidation. Despite unchanged creatinine levels, the prediabetic animals presented glomerular crescent-like lesions, accompanied by increased kidney Oil-Red-O staining, triglycerides content and mRNA expression of IL-6 and iNOS. This model of HSuHF-induced prediabetes can be a useful tool to study early features of DN, namely crescent-like lesions, an early signature that deserves in-depth elucidation.

Dietary fibre and whole grains in diabetes management: Systematic review and meta-analyses. PLoS Med 2020; 17:e1003053. [PMID: 32142510 PMCID: PMC7059907 DOI: 10.1371/journal.pmed.1003053] [Citation(s) in RCA: 195] [Impact Index Per Article: 48.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/03/2019] [Accepted: 02/03/2020] [Indexed: 01/08/2023] Open
Abstract
BACKGROUND Fibre is promoted as part of a healthy dietary pattern and in diabetes management. We have considered the role of high-fibre diets on mortality and increasing fibre intake on glycaemic control and other cardiometabolic risk factors of adults with prediabetes or diabetes. METHODS AND FINDINGS We conducted a systematic review of published literature to identify prospective studies or controlled trials that have examined the effects of a higher fibre intake without additional dietary or other lifestyle modification in adults with prediabetes, gestational diabetes, type 1 diabetes, and type 2 diabetes. Meta-analyses were undertaken to determine the effects of higher fibre intake on all-cause and cardiovascular mortality and increasing fibre intake on glycaemic control and a range of cardiometabolic risk factors. For trials, meta regression analyses identified further variables that influenced the pooled findings. Dose response testing was undertaken; Grading of Recommendations Assessment, Development and Evaluation (GRADE) protocols were followed to assess the quality of evidence. Two multicountry cohorts of 8,300 adults with type 1 or type 2 diabetes followed on average for 8.8 years and 42 trials including 1,789 adults with prediabetes, type 1, or type 2 diabetes were identified. Prospective cohort data indicate an absolute reduction of 14 fewer deaths (95% confidence interval (CI) 4-19) per 1,000 participants over the study duration, when comparing a daily dietary fibre intake of 35 g with the average intake of 19 g, with a clear dose response relationship apparent. Increased fibre intakes reduced glycated haemoglobin (HbA1c; mean difference [MD] -2.00 mmol/mol, 95% CI -3.30 to -0.71 from 33 trials), fasting plasma glucose (MD -0.56 mmol/L, 95% CI -0.73 to -0.38 from 34 trials), insulin (standardised mean difference [SMD] -2.03, 95% CI -2.92 to -1.13 from 19 trials), homeostatic model assessment of insulin resistance (HOMA IR; MD -1.24 mg/dL, 95% CI -1.72 to -0.76 from 9 trials), total cholesterol (MD -0.34 mmol/L, 95% CI -0.46 to -0.22 from 27 trials), low-density lipoprotein (LDL) cholesterol (MD -0.17 mmol/L, 95% CI -0.27 to -0.08 from 21 trials), triglycerides (MD -0.16 mmol/L, 95% CI -0.23 to -0.09 from 28 trials), body weight (MD -0.56 kg, 95% CI -0.98 to -0.13 from 18 trials), Body Mass Index (BMI; MD -0.36, 95% CI -0·55 to -0·16 from 14 trials), and C-reactive protein (SMD -2.80, 95% CI -4.52 to -1.09 from 7 trials) when compared with lower fibre diets. All trial analyses were subject to high heterogeneity. Key variables beyond increasing fibre intake were the fibre intake at baseline, the global region where the trials were conducted, and participant inclusion criteria other than diabetes type. Potential limitations were the lack of prospective cohort data in non-European countries and the lack of long-term (12 months or greater) controlled trials of increasing fibre intakes in adults with diabetes. CONCLUSIONS Higher-fibre diets are an important component of diabetes management, resulting in improvements in measures of glycaemic control, blood lipids, body weight, and inflammation, as well as a reduction in premature mortality. These benefits were not confined to any fibre type or to any type of diabetes and were apparent across the range of intakes, although greater improvements in glycaemic control were observed for those moving from low to moderate or high intakes. Based on these findings, increasing daily fibre intake by 15 g or to 35 g might be a reasonable target that would be expected to reduce risk of premature mortality in adults with diabetes.

Dietary patterns and management of type 2 diabetes: A systematic review of randomised clinical trials. Nutr Metab Cardiovasc Dis 2019; 29:531-543. [PMID: 30952576 DOI: 10.1016/j.numecd.2019.02.004] [Citation(s) in RCA: 77] [Impact Index Per Article: 15.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/26/2018] [Revised: 02/11/2019] [Accepted: 02/11/2019] [Indexed: 11/28/2022]
Abstract
BACKGROUND AND AIM The aim of the present review is to examine evidence from published studies on the effectiveness of six or more months of low carbohydrate, macrobiotic, vegan, vegetarian, Mediterranean and intermittent fasting (IF) diets compared to low fat diets on diabetes control and management. METHODS AND RESULTS In accordance with PRISMA guidelines, Cochrane CENTRAL, PubMed and Scopus databases were systematically searched for relevant studies. Twenty randomised controlled trials (RCTs) > 6 months that investigated the effectiveness of various dietary patterns on type 2 diabetes mellitus (T2DM) were included. Risk of bias was assessed using the Cochrane tool. There were no significant differences in glycemic control, weight and lipids for the majority of low carbohydrate diets (LCDs) compared to low fat diets (LFDs). Four out of fifteen LCD interventions showed better glycemic control while weight loss was greater in one study. The Mediterranean dietary pattern demonstrated greater reduction in body weight and HbA1c levels and delayed requirement for diabetes medications. The vegan and macrobiotic diet demonstrated improved glycemic control, while the vegetarian diet showed greater body weight reduction and insulin sensitivity. CONCLUSIONS Although more long-term intervention trials are required, mounting evidence supports the view that vegan, vegetarian and Mediterranean dietary patterns should be implemented in public health strategies, in order to better control glycemic markers in individuals with T2DM.

Cardiovascular disease risk factor responses to a type 2 diabetes care model including nutritional ketosis induced by sustained carbohydrate restriction at 1 year: an open label, non-randomized, controlled study. Cardiovasc Diabetol 2018; 17:56. [PMID: 29712560 PMCID: PMC5928595 DOI: 10.1186/s12933-018-0698-8] [Citation(s) in RCA: 116] [Impact Index Per Article: 19.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/09/2018] [Accepted: 04/02/2018] [Indexed: 01/17/2023] Open
Abstract
BACKGROUND Cardiovascular disease (CVD) is a leading cause of death among adults with type 2 diabetes mellitus (T2D). We recently reported that glycemic control in patients with T2D can be significantly improved through a continuous care intervention (CCI) including nutritional ketosis. The purpose of this study was to examine CVD risk factors in this cohort. METHODS We investigated CVD risk factors in patients with T2D who participated in a 1 year open label, non-randomized, controlled study. The CCI group (n = 262) received treatment from a health coach and medical provider. A usual care (UC) group (n = 87) was independently recruited to track customary T2D progression. Circulating biomarkers of cholesterol metabolism and inflammation, blood pressure (BP), carotid intima media thickness (cIMT), multi-factorial risk scores and medication use were examined. A significance level of P < 0.0019 ensured two-tailed significance at the 5% level when Bonferroni adjusted for multiple comparisons. RESULTS The CCI group consisted of 262 participants (baseline mean (SD): age 54 (8) year, BMI 40.4 (8.8) kg m-2). Intention-to-treat analysis (% change) revealed the following at 1-year: total LDL-particles (LDL-P) (- 4.9%, P = 0.02), small LDL-P (- 20.8%, P = 1.2 × 10-12), LDL-P size (+ 1.1%, P = 6.0 × 10-10), ApoB (- 1.6%, P = 0.37), ApoA1 (+ 9.8%, P < 10-16), ApoB/ApoA1 ratio (- 9.5%, P = 1.9 × 10-7), triglyceride/HDL-C ratio (- 29.1%, P < 10-16), large VLDL-P (- 38.9%, P = 4.2 × 10-15), and LDL-C (+ 9.9%, P = 4.9 × 10-5). Additional effects were reductions in blood pressure, high sensitivity C-reactive protein, and white blood cell count (all P < 1 × 10-7) while cIMT was unchanged. The 10-year atherosclerotic cardiovascular disease (ASCVD) risk score decreased - 11.9% (P = 4.9 × 10-5). Antihypertensive medication use was discontinued in 11.4% of CCI participants (P = 5.3 × 10-5). The UC group of 87 participants [baseline mean (SD): age 52 (10) year, BMI 36.7 (7.2) kg m-2] showed no significant changes. After adjusting for baseline differences when comparing CCI and UC groups, significant improvements for the CCI group included small LDL-P, ApoA1, triglyceride/HDL-C ratio, HDL-C, hsCRP, and LP-IR score in addition to other biomarkers that were previously reported. The CCI group showed a greater rise in LDL-C. CONCLUSIONS A continuous care treatment including nutritional ketosis in patients with T2D improved most biomarkers of CVD risk after 1 year. The increase in LDL-cholesterol appeared limited to the large LDL subfraction. LDL particle size increased, total LDL-P and ApoB were unchanged, and inflammation and blood pressure decreased. Trial registration Clinicaltrials.gov: NCT02519309. Registered 10 August 2015.

Severe hypoglycaemia among patients with type 2 diabetes requiring emergency hospital admission: The Hypoglycaemia In Portugal Observational Study-Emergency Room (HIPOS-ER). Diabetes Obes Metab 2018; 20:50-59. [PMID: 28581253 DOI: 10.1111/dom.13030] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/09/2017] [Revised: 05/19/2017] [Accepted: 05/30/2017] [Indexed: 11/28/2022]
Abstract
AIMS To analyse the prevalence of severe hypoglycaemia in patients with type 2 diabetes (T2DM) treated with antihyperglycaemic agents (AHA) and requiring emergency room (ER) assistance, and to analyse the prevalence according to type of AHA therapy. METHODS The present study, the Hypoglycaemia In Portugal Observational Study-Emergency Room (HIPOS-ER), was a cross-sectional, observational, multicentre, nationwide study, with specific hypoglycaemia source data collection. RESULTS Within the study period, a total of 425 706 admissions were recorded in the ERs of participating hospitals. The prevalence of severe hypoglycaemic episodes in patients with T2DM was 0.074%. In all, 238 patients were included, more than half of whom were on insulin-based therapy (55.0%) and a third of whom (31.5%) were on oral secretagogue-based therapy. In 61.2% of patients primary care was the main diabetes care setting. The median patient age was 77.5 years and the mean duration of diabetes was 19 years. Missing a meal or low carbohydrate meal content was the most frequent cause of hypoglycaemia (55.9%) and the most frequent triggers for seeking emergency assistance were pre-syncope (19.2%) and transient loss of consciousness (17.4%). A total of 44.1% of patients were hospitalized for a median of 5.1 days. Patients in the secretagogue group were admitted to hospital more often than patients in the insulin group (70.7% vs 29.0%; P < .001). Nine patients died. CONCLUSIONS These findings confirm that severe hypoglycaemia in patients with T2DM requiring ER assistance occurs mainly in those on insulin- and secretagogue-based therapies and is associated with a significant medical burden. Antidiabetic therapy should be individualized to minimize the risk of severe iatrogenic hypoglycaemia, and any intervention to this end should always involve primary care stakeholders.

Roles of increased glycaemic variability, GLP-1 and glucagon in hypoglycaemia after Roux-en-Y gastric bypass. Eur J Endocrinol 2017; 177:455-464.

Abstract
OBJECTIVE Roux-en-Y gastric bypass (RYGB) surgery is currently the most effective treatment for diabetes and obesity. An increasingly recognized and highly disabling complication of RYGB is postprandial hypoglycaemia (PPH). The pathophysiology of PPH remains unclear with multiple mechanisms suggested including nesidioblastosis, altered insulin clearance and increased glucagon-like peptide-1 (GLP-1) secretion. Whilst many PPH patients respond to dietary modification, some have severely disabling symptoms. Multiple treatments are proposed, including dietary modification, GLP-1 antagonism, GLP-1 analogues and even surgical reversal, with none showing a more decided advantage over the others. A greater understanding of the pathophysiology of PPH could guide the development of new therapeutic strategies. METHODS We studied a cohort of PPH patients at the Imperial Weight Center. We performed continuous glucose monitoring to characterize their altered glycaemic variability. We also performed a mixed meal test (MMT) and measured gut hormone concentrations. RESULTS We found increased glycaemic variability in our cohort of PPH patients, specifically a higher mean amplitude glucose excursion (MAGE) score of 4.9. We observed significantly greater and earlier increases in insulin, GLP-1 and glucagon in patients who had hypoglycaemia in response to an MMT (MMT Hypo) relative to those that did not (MMT Non-Hypo). No significant differences in oxyntomodulin, GIP or peptide YY secretion were seen between these two groups. CONCLUSION An early peak in GLP-1 and glucagon may together trigger an exaggerated insulinotropic response to eating and consequent hypoglycaemia in patients with PPH.

Abstract
BACKGROUND The prevention of postexercise nocturnal hypoglycemia after prolonged physical activity using sensor-augmented pump (SAP) therapy with predictive low-glucose management (PLGM) has not been well studied. We conducted a study at a pediatric diabetes camp to determine whether a SAP with PLGM reduces the frequency of nocturnal hypoglycemia after prolonged physical activity more effectively than a SAP with a carbohydrate intake algorithm. METHODS During a 1-week sport camp, 20 children (aged 10-13 years) with type 1 diabetes (T1D) managed by SAP therapy either with (n = 7) or without PLGM (n = 13) were studied. The hypoglycemia management strategy and the continuous glucose monitoring (CGM)/PLGM settings were standardized. The incidence, severity, and duration of hypoglycemia and carbohydrate intake were documented and compared. RESULTS The PLGM system was activated on 78% of all nights (once per night on average). No difference was found between the SAP and PLGM groups in the mean overnight glucose curve or mean morning glucose (7.8 ± 2 mmol/L vs. 7.4 ± 3 mmol/L). There was no difference in the frequency and severity of hypoglycemia. However, the SAP group consumed significantly more carbohydrates to prevent and treat hypoglycemia than those in the PLGM group; the values were 10 ± 2 and 1 ± 2 gS (P < 0.0001) in the SAP and PLGM groups, respectively. Moreover, the SAP group spent a significantly longer time in hypoglycemia (64 ± 2 min vs. 38 ± 2 min, P < 0.05). We observed a difference in the time distribution of nocturnal hypoglycemia (10 to 12 p.m. in the PLGM group and 3 to 7 a.m. in the SAP group, P < 0.05). CONCLUSION With PLGM system, euglycemia after prolonged physical activity was largely maintained with a minimal carbohydrate intake.

Fear of hypoglycemia: Influence on glycemic variability and self-management behavior in young adults with type 1 diabetes. J Diabetes Complications 2017; 31:735-741. [PMID: 28143733 PMCID: PMC5350014 DOI: 10.1016/j.jdiacomp.2016.12.015] [Citation(s) in RCA: 74] [Impact Index Per Article: 10.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/27/2016] [Revised: 12/16/2016] [Accepted: 12/22/2016] [Indexed: 12/29/2022]
Abstract
PURPOSE The purpose of this study was to examine how fear of hypoglycemia (FOH) is associated with glycemic variability (GV) and self-management behavior in young adults (aged 18-35) with type 1 diabetes (T1DM). PROCEDURES Using a prospective repeated-measures design, in 35 young adults, within- and between-person and temporal associations of FOH, specific self-management behaviors, and GV were measured. The data were collected using questionnaires and real-time measures using daily diaries, insulin pump downloads, actigraphy, and continuous glucose monitoring. FINDINGS FOH was associated with greater glycemic variability. Significant temporal associations emerged. Concurrent day (glucose SD, p=.011) and previous-evening fear levels were associated with GV (glucose SD, p=.007). FOH was also associated with greater calorie intake (r=.492, p=.003) and less physical activity (light activity, r=-.341, p=.045). CONCLUSIONS The significant associations of FOH with GV, dietary patterns, and physical activity provide evidence for FOH as an important psychological factor associated with diabetes care.

Abstract
OBJECTIVE To formulate clinical practice guidelines for the use of continuous glucose monitoring and continuous subcutaneous insulin infusion in adults with diabetes. PARTICIPANTS The participants include an Endocrine Society-appointed Task Force of seven experts, a methodologist, and a medical writer. The American Association for Clinical Chemistry, the American Association of Diabetes Educators, and the European Society of Endocrinology co-sponsored this guideline. EVIDENCE The Task Force developed this evidence-based guideline using the Grading of Recommendations, Assessment, Development, and Evaluation system to describe the strength of recommendations and the quality of evidence. The Task Force commissioned one systematic review and used the best available evidence from other published systematic reviews and individual studies. CONSENSUS PROCESS One group meeting, several conference calls, and e-mail communications enabled consensus. Committees and members of the Endocrine Society, the American Association for Clinical Chemistry, the American Association of Diabetes Educators, and the European Society of Endocrinology reviewed and commented on preliminary drafts of these guidelines. CONCLUSIONS Continuous subcutaneous insulin infusion and continuous glucose monitoring have an important role in the treatment of diabetes. Data from randomized controlled trials are limited on the use of medical devices, but existing studies support the use of diabetes technology for a wide variety of indications. This guideline presents a review of the literature and practice recommendations for appropriate device use.

"A Vegetarian vs. Conventional Hypocaloric Diet: The Effect on Physical Fitness in Response to Aerobic Exercise in Patients with Type 2 Diabetes." A Parallel Randomized Study. Nutrients 2016; 8:nu8110671. [PMID: 27792174 PMCID: PMC5133059 DOI: 10.3390/nu8110671] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2016] [Revised: 10/06/2016] [Accepted: 10/17/2016] [Indexed: 11/24/2022] Open
Abstract
It has been shown that it is possible to modify macronutrient oxidation, physical fitness and resting energy expenditure (REE) by changes in diet composition. Furthermore, mitochondrial oxidation can be significantly increased by a diet with a low glycemic index. The purpose of our trial was to compare the effects of a vegetarian (V) and conventional diet (C) with the same caloric restriction (−500 kcal/day) on physical fitness and REE after 12 weeks of diet plus aerobic exercise in 74 patients with type 2 diabetes (T2D). An open, parallel, randomized study design was used. All meals were provided for the whole study duration. An individualized exercise program was prescribed to the participants and was conducted under supervision. Physical fitness was measured by spiroergometry and indirect calorimetry was performed at the start and after 12 weeks Repeated-measures ANOVA (Analysis of variance) models with between-subject (group) and within-subject (time) factors and interactions were used for evaluation of the relationships between continuous variables and factors. Maximal oxygen consumption (VO2max) increased by 12% in vegetarian group (V) (F = 13.1, p < 0.001, partial η2 = 0.171), whereas no significant change was observed in C (F = 0.7, p = 0.667; group × time F = 9.3, p = 0.004, partial η2 = 0.209). Maximal performance (Watt max) increased by 21% in V (F = 8.3, p < 0.001, partial η2 = 0.192), whereas it did not change in C (F = 1.0, p = 0.334; group × time F = 4.2, p = 0.048, partial η2 = 0.116). Our results indicate that V leads more effectively to improvement in physical fitness than C after aerobic exercise program.

Emerging Evidence for the Importance of Dietary Protein Source on Glucoregulatory Markers and Type 2 Diabetes: Different Effects of Dairy, Meat, Fish, Egg, and Plant Protein Foods. Nutrients 2016; 8:nu8080446. [PMID: 27455320 PMCID: PMC4997361 DOI: 10.3390/nu8080446] [Citation(s) in RCA: 60] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2016] [Revised: 07/13/2016] [Accepted: 07/19/2016] [Indexed: 02/07/2023] Open
Abstract
Observational studies provide evidence that a higher intake of protein from plant-based foods and certain animal-based foods is associated with a lower risk for type 2 diabetes. However, there are few distinguishable differences between the glucoregulatory qualities of the proteins in plant-based foods, and it is likely their numerous non-protein components (e.g., fibers and phytochemicals) that drive the relationship with type 2 diabetes risk reduction. Conversely, the glucoregulatory qualities of the proteins in animal-based foods are extremely divergent, with a higher intake of certain animal-based protein foods showing negative effects, and others showing neutral or positive effects on type 2 diabetes risk. Among the various types of animal-based protein foods, a higher intake of dairy products (such as milk, yogurt, cheese and whey protein) consistently shows a beneficial relationship with glucose regulation and/or type 2 diabetes risk reduction. Intervention studies provide evidence that dairy proteins have more potent effects on insulin and incretin secretion compared to other commonly consumed animal proteins. In addition to their protein components, such as insulinogenic amino acids and bioactive peptides, dairy products also contain a food matrix rich in calcium, magnesium, potassium, trans-palmitoleic fatty acids, and low-glycemic index sugars-all of which have been shown to have beneficial effects on aspects of glucose control, insulin secretion, insulin sensitivity and/or type 2 diabetes risk. Furthermore, fermentation and fortification of dairy products with probiotics and vitamin D may improve a dairy product's glucoregulatory effects.

The relationship of diabetes-related distress and depressive symptoms with physical activity and dietary behaviors in adults with type 2 diabetes: A cross-sectional study. J Diabetes Complications 2016; 30:967-70. [PMID: 27083444 DOI: 10.1016/j.jdiacomp.2016.02.019] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/05/2016] [Revised: 02/25/2016] [Accepted: 02/26/2016] [Indexed: 11/17/2022]
Abstract
AIMS Diabetes-related distress (DD) and depressive symptoms (DS) may influence self-management behaviors in people living with type 2 diabetes (T2D). We examined the association of DD and DS with physical activity (PA) and adherence to recommended dietary behaviors in adults with T2D. METHODS Using baseline data from 2040 adults with T2D in the Alberta's Caring for Diabetes (ABCD) cohort study, DD, DS, PA and adherence to dietary behaviors were assessed. A composite variable for presence of DD and DS was computed for analyses. ANOVA and logistic regression tested independent associations of DS and DD with PA and adherence to diet. RESULTS Participants were 64±10.6years, 45% female, 76% with annual household income≤$80,000, and 86% with high school education or more. Those with DD alone were 1.8 times (95% CI 1.1, 2.9) and those with DD and DS combined were 2.0 times (95% CI 1.1, 3.7) more likely not to meet PA guidelines compared to those without DD or DS. The presence of DS alone was not significantly associated with meeting PA guidelines (OR 1.4; 95% CI 0.7, 3.0). Compared to those without DD or DS, patients with DD alone (OR 1.5; 95% CI 1.4, 3.4), DS alone (OR 5.2; 95% CI 2.7, 9.7), or DD and DS combined (OR 2.5; 95% CI 1.6, 3.8) were more likely to have poor adherence to recommended dietary behaviors. CONCLUSIONS Greater distress or depressive symptoms were associated with worse self-management behaviors in adults with T2D. Attention to mental health status may improve participation in PA and adherence to diet recommendations in these patients.

Abstract
OBJECTIVE The Look AHEAD trial was a multi-center, randomized controlled trial, to determine whether weight loss reduces cardiovascular morbidity and mortality in overweight individuals with type 2 diabetes. The objective of this study was to evaluate the incidence of severe hypoglycemia in patients enrolled in Look AHEAD. Research Design and Methods 5,145 subjects were randomized to diabetes support and education (DSE) or intensive lifestyle intervention (ILI). Instances of severe hypoglycemia were recorded. Regression analysis was used to compare the development of severe hypoglycemia between groups. RESULTS Over the entire study, the severe hypoglycemia rate was not different between ILI and DSE groups (0.49 ILI, 0.51 DSE/100 person-years, rate ratio=1.12, p=0.41), but was greater in ILI during year 1 (p=0.008 for year by intervention interaction). During follow-up, severe hypoglycemia risk was higher with insulin, sulfonylurea or glitinide use at baseline (p<0.0001). The intervention effect differed by post-randomization insulin use (ILI to DSE HR=1.45 in insulin users versus HR=0.71 in non-users, p=0.009). Insulin use reduced by 3% in ILI in year 1. Compared to DSE, ILI participants in the lower 50% of weight loss in year 1 had similar percent insulin use and incident hypoglycemia, but ILI participants in the upper 50% of weight loss had lower percent insulin use and incident hypoglycemia. CONCLUSIONS Reduction in insulin is necessary during intensive weight loss to avoid episodes of hypoglycemia. Although limited by self-reported evaluation of hypoglycemia, greater weight loss in ILI during year 1 was associated with reduced insulin use and lower rates of hypoglycemia later in the trial.

Efficacy and acceptability of very low energy diets in overweight and obese people with Type 2 diabetes mellitus: a systematic review with meta-analyses. Diabet Med 2016; 33:580-91. [PMID: 26490082 DOI: 10.1111/dme.13005] [Citation(s) in RCA: 35] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/16/2015] [Revised: 08/28/2015] [Accepted: 10/16/2015] [Indexed: 02/06/2023]
Abstract
AIMS To explore the efficacy and acceptability of very low energy diets in overweight or obese adults with Type 2 diabetes. METHODS Controlled trials and qualitative studies of individuals with Type 2 diabetes that compared very low energy diets with standard care, minimal interventions, other weight loss interventions, less intensive very low energy diet interventions and very low energy diets with additional components were eligible for inclusion. Meta-analyses of changes in weight, blood glucose levels and attrition rates were performed. Acceptability of very low energy diets was assessed by attrition rates, number and severity of side effects, and by qualitative evaluations of the interventions. RESULTS Four randomized, five non-randomized controlled trials and no qualitative studies (21 references, 9 studies, 346 participants) were identified. Meta-analyses showed that very low energy diets induced greater weight losses than minimal interventions, standard care or low energy diets at 3 and 6 months. No conclusive evidence for differences in outcomes between very low energy diets and Roux-en-Y gastric bypass surgery was found. Greater differences in energy prescription between intervention and comparator arms were associated with greater differences in weight loss and fasting blood glucose levels at 3 months. Attrition rates did not differ between the very low energy diets and the comparator arms at any measurement point. CONCLUSIONS Very low energy diets are effective in substantial weight loss among people with Type 2 diabetes. Levels of adherence to very low energy diets in controlled studies appear to be high, although details about behaviour support provided are usually poorly described.

Abstract
AIM To determine the effects of protein alone (independent of fat and carbohydrate) on postprandial glycaemia in individuals with Type 1 diabetes mellitus using intensive insulin therapy. METHODS Participants with Type 1 diabetes mellitus aged 7-40 years consumed six 150 ml whey isolate protein drinks [0 g (control), 12.5, 25, 50, 75 and 100] and two 150 ml glucose drinks (10 and 20 g) without insulin, in randomized order over 8 days, 4 h after the evening meal. Continuous glucose monitoring was used to assess postprandial glycaemia. RESULTS Data were collected from 27 participants. Protein loads of 12.5 and 50 g did not result in significant postprandial glycaemic excursions compared with control (water) throughout the 300 min study period (P > 0.05). Protein loads of 75 and 100 g resulted in lower glycaemic excursions than control in the 60-120 min postprandial interval, but higher excursions in the 180-300 min interval. In comparison with 20 g glucose, the large protein loads resulted in significantly delayed and sustained glucose excursions, commencing at 180 min and continuing to 5 h. CONCLUSIONS Seventy-five grams or more of protein alone significantly increases postprandial glycaemia from 3 to 5 h in people with Type 1 diabetes mellitus using intensive insulin therapy. The glycaemic profiles resulting from high protein loads differ significantly from the excursion from glucose in terms of time to peak glucose and duration of the glycaemic excursion. This research supports recommendations for insulin dosing for large amounts of protein.

Abstract
AIMS The efficacy of low-carbohydrate diets (LCD) in people with Type 2 diabetes has divided the nutrition community. This review seeks to re-examine the available data to clarify understanding. METHODS A comprehensive search of databases was used to identify meta-analyses of LCD in Type 2 diabetes. To improve the quality of the studies analysed, the following inclusion criteria were applied: randomized control trials ≥ 4 weeks in people aged > 18 years with Type 2 diabetes; a carbohydrate intake ≤ 45% of total energy intake per day; and a dietary intake assessment at the end of the study. The resulting studies were subjected to a thematic analysis. RESULTS Nine meta-analyses were identified containing 153 studies. Twelve studies met our amended inclusion criteria. There were no significant differences in metabolic markers, including glycaemic control, between the two diets, although weight loss with a LCD was greater in one study. Carbohydrate intake at 1 year in very LCD (< 50 g of carbohydrates) ranged from 132 to 162 g. In some studies, the difference between diets was as little as 8 g/day of carbohydrates. CONCLUSION Total energy intake remains the dietary predictor of body weight. A LCD appears no different from a high-carbohydrate diet in terms of metabolic markers and glycaemic control. Very LCDs may not be sustainable over a medium to longer term as carbohydrate intake in diets within studies often converged toward a more moderate level. The variable quality of studies included in earlier meta-analyses likely explains the previous inconsistent findings between meta-analyses.

"I Don't Want Them to Feel Different": A Mixed Methods Study of Parents' Beliefs and Dietary Management Strategies for Their Young Children with Type 1 Diabetes Mellitus. J Acad Nutr Diet 2016; 116:272-282. [PMID: 26260671 PMCID: PMC4733405 DOI: 10.1016/j.jand.2015.06.377] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2014] [Accepted: 06/22/2015] [Indexed: 11/23/2022]
Abstract
BACKGROUND Many young children with type 1 diabetes mellitus (T1DM) do not consume a healthful diet; exactly why this occurs despite T1DM education remains poorly understood. OBJECTIVE This study describes parents' perceptions of healthful eating for T1DM in young children and identifies factors related to parents' dietary management. DESIGN A cross-sectional, mixed-methods study was performed. Parents completed a questionnaire, 3-day weighed diet record, and a semi-structured interview regarding their perceptions of healthful eating for T1DM and their dietary management practices. PARTICIPANTS/SETTING Twenty-three families, recruited from a pediatric diabetes clinic in the midwestern United States between February 2012 and April 2013, participated. Eligible families had a child with T1DM who was 1 to 6 years old, at least 6 months from diagnosis, and was following an intensive insulin regimen. STATISTICAL ANALYSES PERFORMED Mean scores and percentages were calculated from the diet diaries and parent questionnaires, and parents' interviews were coded to identify common themes. RESULTS Results showed that while parents may believe they know what constitutes a healthful diet for T1DM, they do not always feed their child a healthful diet. Parent-identified barriers to healthful eating included limited time to prepare homemade meals, perceived higher costs of healthier foods, the influence of peers on children's food preferences, and picky eating. Parents also discussed a desire not to limit their child's diet or make their child "feel different," which many parents said often led them to give into their child's requests for less healthful food options. CONCLUSIONS Parents of young children with T1DM identified several barriers to healthful eating that are common for all parents, such as time constraints, expense, and child food preferences. However, unique themes emerged, including parents' desire not to limit their child's diet or make their child "feel different." Nutrition components of T1DM education should include psychological and behavioral strategies to help parents manage these unique concerns.

Abstract
AIMS To identify the knowledge and management factors associated with glycaemic control among adults with Type 1 diabetes mellitus treated with insulin pump therapy. METHODS A cross-sectional study of adults with Type 1 diabetes mellitus on insulin pump therapy for at least 12 months (n = 50, 18-70 years old) was undertaken between December 2013 and May 2014. A new questionnaire was developed to evaluate participants' knowledge and management related to insulin pump therapy, and were correlated with insulin pump data, HbA1c and frequency of hypoglycaemia. RESULTS Participants who changed their insulin pump settings when indicated had significantly better glycaemic control than those who did not (P = 0.04). Multivariate logistic regression analysis found that better overall insulin pump therapy management was a significant predictor of better glycaemic control (odds ratio 4.45, 95% confidence interval 1.61-12.3; P = 0.004) after adjusting for potential confounders including age, gender, duration of diabetes and insulin pump therapy. However, overall insulin pump therapy knowledge was not a significant predictor of glycaemic control (P = 0.058). There was no significant association between frequency of hypoglycaemia and insulin pump therapy knowledge or management. CONCLUSIONS We identified some key knowledge and management factors associated with glycaemic control in adults with Type 1 diabetes mellitus on insulin pump therapy using a newly designed questionnaire. The pilot study assessed the clinical utility of this evaluation tool, which may facilitate provision of targeted education to insulin pump therapy users to achieve optimal glycaemic control.

Abstract
AIM This study aimed to investigate the nutritional status of patients with limb-threatening diabetic foot ulcers (DFUs) and its impact on treatment outcomes. METHODS A total of 478 consecutive patients (mean age, 65.4years) treated for limb-threatening DFUs were enrolled. Nutritional status assessment using the Mini Nutritional Assessment (MNA) and Geriatric Nutritional Risk Index (GNRI) was performed by three qualified dieticians within 48hours of admission. Limb-preservation outcomes were stratified into major lower extremity amputation (LEA) (above the ankle, n=33), minor LEA (distal to ankle, n=117) and no amputation (non-LEA, n=328). RESULTS Most patients were identified as being at risk of malnutrition (70.5%) or malnourished (14.6%) (mean MNA score, 20.6±3.4). MNA scores decreased with increasing severity of LEA (mean, 21.1, 20.0, and 17.9, respectively; P for linear trend <0.001), associated inversely with the tendency to require LEA (P for linear trend was 0.001), and associated independently with both major and minor LEA outcomes (adjusted odds ratio [aOR]=0.80, 95% confidence interval [CI], 0.65-0.99, P=0.042 and aOR=0.89, 95% CI, 0.80-0.99, P=0.032, respectively). The predictive value was sustained in patients younger than age 65years. Though GNRI results had similar associations with outcomes, its predictive value was limited in minor LEA and younger population. CONCLUSIONS Patients' nutritional status was shown to have significant influence on limb-preservation outcomes for limb-threatening DFUs. Nutritional assessment of this patient population using the MNA is recommended.

Abstract
AIM This pilot study evaluated the short-term benefits of a telemonitoring-supplemented focused diabetic education compared with education alone in participants with Type 2 diabetes who were fasting during Ramadan. METHODS In this pilot mixed-method study, we identified 37 participants and randomly allocated them to either a telemonitoring group (n = 18) or a group receiving Ramadan-focused pre-education only (usual care; n = 19). The telemonitoring group received goal-setting and personalized feedback. RESULTS The telemonitoring group was less likely to experience hypoglycaemia than the usual care group (odds ratio: 0.1273; 95% confidence interval: 0.0267-0.6059). No significant differences were noted in glycaemic control at the end of study. Participants viewed telemedicine as a more convenient alternative although technological barriers remain a concern. CONCLUSIONS The results of this study reinforce the need for monitoring as well as educational initiatives for Muslims with diabetes who fast during Ramadan. Telemonitoring offers an attractive option requiring further research. (Clinical Trial Registry No. NCT02189135).

Abstract
AIMS To investigate the relationship between diabetes duration and diabetes-related distress and to examine the impact of micro- and macrovascular complications and blood glucose-lowering treatment on this relationship. METHODS We conducted a cross-sectional study in people with Type 2 diabetes who participated in the Dutch Diacourse study (n = 590) and completed the Problem Areas in Diabetes questionnaire. Data on diabetes duration, micro- and macrovascular complications and blood glucose-lowering treatment were collected. Multiple linear regression analysis was used to investigate the association between diabetes duration and diabetes-related distress, and to examine whether complications and treatment could explain this association. RESULTS A significant linear and quadratic association between diabetes duration and diabetes-related distress was found (duration: β = 0.27, P = 0.005; duration(2): β = -0.21, P = 0.030). The association between duration and distress could be explained by microvascular complications and insulin treatment, which were both more often present in people with a longer diabetes duration, and were associated with higher levels of diabetes-related distress (β = 0.20, P < 0.001 and β = 0.16, P = 0.006 respectively). Duration, age, gender, complications and treatment together explained 13.1% of the variance in distress. CONCLUSIONS Diabetes duration was associated with diabetes-related distress. This association can be explained largely by the presence of diabetes-related microvascular complications and insulin treatment. Healthcare providers should focus on distress in people with Type 2 diabetes in different stages over the course of illness, especially when complications are present or when people are on insulin treatment. As well as diabetes duration, complications and blood glucose-lowering treatment, diabetes-related distress is likely to be influenced by many other factors.

One Egg per Day Improves Inflammation when Compared to an Oatmeal-Based Breakfast without Increasing Other Cardiometabolic Risk Factors in Diabetic Patients. Nutrients 2015; 7:3449-63.

Abstract
There is concern that egg intake may increase blood glucose in patients with type 2 diabetes mellitus (T2DM). However, we have previously shown that eggs reduce inflammation in patients at risk for T2DM, including obese subjects and those with metabolic syndrome. Thus, we hypothesized that egg intake would not alter plasma glucose in T2DM patients when compared to oatmeal intake. Our primary endpoints for this clinical intervention were plasma glucose and the inflammatory markers tumor necrosis factor (TNF)-α and interleukin 6 (IL-6). As secondary endpoints, we evaluated additional parameters of glucose metabolism, dyslipidemias, oxidative stress and inflammation. Twenty-nine subjects, 35–65 years with glycosylated hemoglobin (HbA1c) values <9% were recruited and randomly allocated to consume isocaloric breakfasts containing either one egg/day or 40 g of oatmeal with 472 mL of lactose-free milk/day for five weeks. Following a three-week washout period, subjects were assigned to the alternate breakfast. At the end of each period, we measured all primary and secondary endpoints. Subjects completed four-day dietary recalls and one exercise questionnaire for each breakfast period. There were no significant differences in plasma glucose, our primary endpoint, plasma lipids, lipoprotein size or subfraction concentrations, insulin, HbA1c, apolipoprotein B, oxidized LDL or C-reactive protein. However, after adjusting for gender, age and body mass index, aspartate amino-transferase (AST) (p < 0.05) and tumor necrosis factor (TNF)-α (p < 0.01), one of our primary endpoints were significantly reduced during the egg period. These results suggest that compared to an oatmeal-based breakfast, eggs do not have any detrimental effects on lipoprotein or glucose metabolism in T2DM. In contrast, eggs reduce AST and TNF-α in this population characterized by chronic low-grade inflammation.

Abstract
AIM This study compares health-related quality of life (HRQL) in patients with type 2 diabetes (T2DM) across treatment groups and explores gender differences. METHODS Four regional surveys (KORA, CARLA, SHIP, DHS) and a national survey (GNHIES98) were pooled at individual level. HRQL was assessed with the SF-12/-36v1. Linear regression models were used to assess the effect of T2DM by treatment type (no medication; oral; oral/insulin combination; insulin) on the physical (PCS-12) and mental summary score (MCS-12) and the SF-6D, controlling for age, sex, study and covariates. We also performed an explanatory analysis of single items. RESULTS PCS-12 scores and treatment type were associated (P-value 0.006), with lowest values for insulin treatment (-4.44 vs. oral; -4.41 vs. combination). MCS-12 scores were associated with treatment type and gender (P-value <0.012), with lower scores for women undergoing oral (-4.25 vs. men) and combination treatment (-6.99 vs. men). Similar results were observed for SF-6D utilities and single items, related to mental health, social functioning, vitality and role limitation (emotional). Comorbidities were predictors of lower PCS-12 and SF-6D scores. CONCLUSIONS T2DM treatment impacts differently on physical and mental HRQL and on women and men. Further studies of gender-specific perceptions of T2DM treatment regimens are needed.

Abstract
AIM To explore adolescents' views and experiences of different treatments for Type 2 diabetes, in order to improve treatment concordance and consider how the current treatment pathway for adolescent Type 2 diabetes could be improved. METHODS In-depth interviews were held with 12 adolescents who had been diagnosed with Type 2 diabetes. Adolescents were sampled from a UK cohort study. Data were analysed thematically. RESULTS Interviewees struggled to maintain lifestyle changes. Insulin, metformin and liraglutide were described as effective but, in some cases, as resulting in side effects. Injected treatments were viewed less favourably than oral medications. Weight loss surgery was considered an acceptable treatment for obese adolescents who had tried other treatments for their diabetes. It was apparent that some adolescents had not been surprised by their diagnosis and did not fully appreciate the implications of having diabetes. It was also evident that some individuals had not told peers about their diagnosis due to fearing how they would react. Factors identified as improving treatment concordance included reminders and viewing treatment as effective and easy to take. CONCLUSIONS Adolescents want treatments that are effective, discrete, easy to take and do not make them different from their peers. As liraglutide was described as effective, and surgery viewed as acceptable in certain circumstances, greater consideration should be given to their potential role in treating adolescent Type 2 diabetes. Practitioners need to ensure that adolescents appreciate the implications of having diabetes and may want to address adolescents' concerns regarding how others view this condition.

Diabetes-related quality of life is enhanced by glycaemic improvement in older people. Diabet Med 2015; 32:243-9. [PMID: 25307368 DOI: 10.1111/dme.12605] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 10/06/2014] [Indexed: 12/01/2022]
Abstract
AIMS To investigate the validity and reliability of the Audit of Diabetes-Dependent Quality of Life instrument in older Italians with diabetes and to test the association of diabetes-related quality of life with glycaemic control over time. METHODS A total of 558 outpatients with Type 2 diabetes from the Diabetic Unit of the Italian National Research Centre on Aging Hospital in Ancona were enrolled to complete questionnaires (Audit of Diabetes-Dependent Quality of Life-19 and the Short-Form-12), and to undergo clinical and biochemical testing at baseline and at 12 months of follow-up. The overall impact of diabetes using the average weighted impact score from the Audit of Diabetes-Dependent Quality of Life questionnaire was calculated. Participants were categorized according to this score as having either less or more negative diabetes-related quality of life. RESULTS Participants had a mean ± SD age of 67.7 ± 9.2 years and 51.8% were male. Factor analysis and Cronbach's coefficient of internal consistency (Cronbach's α = 0.931) confirmed that the 19 domain-specific Audit of Diabetes-Dependent Quality of Life items could be combined into a single scale in this Italian population. The impact score correlated with the physical (r = 0.275; P < 0.001) and mental components (r = 0.291; P < 0.001) of the Short-Form-12 questionnaire. Significant differences were found according to diabetic complications in specific Audit of Diabetes-Dependent Quality of Life items and impact scores. Insulin use had a greater association with a more negative quality of life compared with other antidiabetic agents. A multivariate linear regression model with restricted linear spline application showed that the relationship between HbA1c and impact score was not linear and that the change in the impact score was associated with improved glycaemic control in those with a less negative diabetes-related quality of life at 12 months. CONCLUSIONS The Audit of Diabetes-Dependent Quality of Life-19 is a valid tool for measuring the impact of diabetes on quality of life in older Italians. Perception of diabetes-related quality of life is associated with glycaemic control over time.

Partial Meal Replacement Plan and Quality of the Diet at 1 Year: Action for Health in Diabetes (Look AHEAD) Trial. J Acad Nutr Diet 2015; 115:731-742. [PMID: 25573655 DOI: 10.1016/j.jand.2014.11.003] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2014] [Accepted: 10/29/2014] [Indexed: 11/20/2022]
Abstract
BACKGROUND Little is known about diet quality with a reduced-energy, low-fat, partial meal replacement plan, especially in individuals with type 2 diabetes. The Action for Health in Diabetes (Look AHEAD) trial implemented a partial meal replacement plan in the Intensive Lifestyle Intervention. OBJECTIVE To compare dietary intake and percent meeting fat-related and food group dietary recommendations in Intensive Lifestyle Intervention and Diabetes Support and Education groups at 12 months. DESIGN A randomized controlled trial comparing Intensive Lifestyle Intervention with Diabetes Support and Education at 0 and 12 months. PARTICIPANTS/SETTING From 16 US sites, the first 50% of participants (aged 45 to 76 years, overweight or obese, with type 2 diabetes) were invited to complete dietary assessments. Complete 0- and 12-month dietary assessments (collected between 2001 and 2004) were available for 2,397 participants (46.6% of total participants), with 1,186 randomized to Diabetes Support and Education group and 1,211 randomized to Intensive Lifestyle Intervention group. MAIN OUTCOME MEASURES A food frequency questionnaire assessed intake: energy; percent energy from protein, fat, carbohydrate, polyunsaturated fatty acids, and saturated fats; trans-fatty acids; cholesterol; fiber; weekly meal replacements; and daily servings from food groups from the Food Guide Pyramid. STATISTICAL ANALYSES PERFORMED Mixed-factor analyses of covariance, using Proc MIXED with a repeated statement, with age, sex, race/ethnicity, education, and income controlled. Unadjusted χ² tests compared percent meeting fat-related and food group recommendations at 12 months. RESULTS At 12 months, Intensive Lifestyle Intervention participants had a significantly lower fat and cholesterol intake and greater fiber intake than Diabetes Support and Education participants. Intensive Lifestyle Intervention participants consumed more servings per day of fruits; vegetables; and milk, yogurt, and cheese; and fewer servings per day of fats, oils, and sweets than Diabetes Support and Education participants. A greater percentage of Intensive Lifestyle Intervention participants than Diabetes Support and Education participants met fat-related and most food group recommendations. Within Intensive Lifestyle Intervention, a greater percentage of participants consuming two or more meal replacements per day than participants consuming less than one meal replacement per day met most fat-related and food group recommendations. CONCLUSIONS The partial meal replacement plan consumed by Intensive Lifestyle Intervention participants was related to superior diet quality.

Managing coeliac disease in patients with diabetes. Diabetes Obes Metab 2015; 17:3-8.

Abstract
The association between coeliac disease and type 1 diabetes has long been established. The combination of genetic susceptibility along with a potential role for gluten in the pathogenesis of autoimmunity makes defining gluten's role in type 1 diabetes extremely important. Evidence supporting the role of a gluten-free diet to improve complications associated with type 1 diabetes is not robust. However there is evidence to support improved growth, bone density and potentially the prevention of additional autoimmune diseases in patients with coeliac disease and type 1 diabetes. The gluten free diet is expensive and challenging to adhere to in people already on a modified diet. Early identification of those who have coeliac disease and would benefit from a gluten-free diet is of utmost importance to prevent complications associated with type 1 diabetes and coeliac disease.

Prevalence of food insecurity in patients with diabetes in western Kenya. Diabet Med 2013; 30:e215-22. [PMID: 23506405 DOI: 10.1111/dme.12174] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/20/2012] [Revised: 12/20/2012] [Accepted: 03/13/2013] [Indexed: 11/28/2022]
Abstract
AIMS To determine the characteristics of patients with diabetes who reported food insecurity at three diabetes clinics in western Kenya. METHODS This study includes routinely collected demographic data at the first presentation of patients with diabetes at clinics in western Kenya from 1 January 2006 to 24 September 2011. A validated questionnaire was used to assess food insecurity with descriptive and comparative statistics being used to analyse the food-secure and food-insecure populations. RESULTS The number of patients presenting to these clinics who were food-secure and those who were food-insecure was 1179 (68.0%) and 554 (32.0%), respectively. Comparative analysis shows a statistically significant difference in weight, BMI, the presence of a caretaker, and use of insulin between the two groups. These variables were lower in the food-insecure group. The overall assessment of the clinic population revealed an abnormally high mean HbA1c concentration of 81 mmol/mol (9.6%). CONCLUSIONS Despite the widely recognized contribution of caloric over-nutrition to the development of diabetes, this study highlights the high prevalence of food insecurity amongst patients with diabetes in rural, resource-constrained settings. Other factors, such as the lower prevalence of obesity, poor glucose control, challenges in the use of insulin because of the risk of hypoglycaemia, and varying subtypes of diabetes in this population, point to the need for additional research in understanding the aetiology, pathophysiology and optimum management of this condition, as well as understanding the effects of enhancing food security.

Abstract
OBJECTIVE To review the evidence about the impact of hypoglycemia on patients with diabetes that has become available since the past reviews of this subject by the American Diabetes Association and The Endocrine Society and to provide guidance about how this new information should be incorporated into clinical practice. PARTICIPANTS Five members of the American Diabetes Association and five members of The Endocrine Society with expertise in different aspects of hypoglycemia were invited by the Chair, who is a member of both, to participate in a planning conference call and a 2-day meeting that was also attended by staff from both organizations. Subsequent communications took place via e-mail and phone calls. The writing group consisted of those invitees who participated in the writing of the manuscript. The workgroup meeting was supported by educational grants to the American Diabetes Association from Lilly USA, LLC and Novo Nordisk and sponsorship to the American Diabetes Association from Sanofi. The sponsors had no input into the development of or content of the report. EVIDENCE The writing group considered data from recent clinical trials and other studies to update the prior workgroup report. Unpublished data were not used. Expert opinion was used to develop some conclusions. CONSENSUS PROCESS Consensus was achieved by group discussion during conference calls and face-to-face meetings, as well as by iterative revisions of the written document. The document was reviewed and approved by the American Diabetes Association's Professional Practice Committee in October 2012 and approved by the Executive Committee of the Board of Directors in November 2012 and was reviewed and approved by The Endocrine Society's Clinical Affairs Core Committee in October 2012 and by Council in November 2012. CONCLUSIONS The workgroup reconfirmed the previous definitions of hypoglycemia in diabetes, reviewed the implications of hypoglycemia on both short- and long-term outcomes, considered the implications of hypoglycemia on treatment outcomes, presented strategies to prevent hypoglycemia, and identified knowledge gaps that should be addressed by future research. In addition, tools for patients to report hypoglycemia at each visit and for clinicians to document counseling are provided.

Influence of diet on dental caries in diabetics. COLLEGIUM ANTROPOLOGICUM 2002; 26:311-7. [PMID: 12137315] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 02/25/2023]
Abstract
Two groups of population consisting of 84 patients suffering from diabetes (60 type I, 24 type II) and 69 nondiabetics of the same age have been examined on: oral hygiene index (OHI), frequency of daily tooth brushing, dietary habits and incidence of dental caries by registration of the decayed, missed and filled dental surfaces (DMFS-index). OHI in type I and type II diabetes was found to bee slightly worse than in nondiabetics, but not significantly (p > 0.05). In the number of daily tooth brushing there is not significant difference between diabetics and nondiabetics. All diabetics have considerably lower daily intake of total as well as simple carbohydrates than nondiabetics. The diabetics have a significantly higher daily intake of dietary fibers, calcium and phosphorus as well as the number of meals with simple carbohydrates and also DMFS-index than the nondiabetics. A significantly higher incidence (p < 0.01) of caries location was found on the buccal and labial cervical areas among patients suffering from diabetes. Explanation for this could be more frequent daily intake of low molecular carbohydrates with an improper calcium phosphorus ratio.

Abstract
Diet has long been part of the treatment. In fact modern dieting in diabetes comes only back 130 years ago with the description given by Apollinaire Bouchardat. He described how excessive glycosuria was observed in the postprandial periods and recommended a low carbohydrate diet. Along with the exclusion of simple sugars introduced 50 years later, the diabetic diet became a very restrictive one partly excluding the patients from normal social life event at home. Recent findings that carbohydrates should better represent 45 to 60% of the total daily caloric intake, that not all refined sugar are that "quick" nor particularly hyperglycaemic, along with the right use of mono-, poly- and saturated fat are now making the diabetic diet more flexible, more attractive, more eclectic. Nowadays we can say that the diet of a diabetic person (type 1 or 2) should follow is very comparable to that a non-diabetic person of the same age, sex, body weight and activity should also follow.

Abstract
Although most patients with type 2 diabetes mellitus can be initially managed with diet and exercise alone, most eventually require at least oral agents if not insulin to maintain glycemic control. Appropriate therapeutic regimens may be difficult to design, given the diversity of drugs available for clinical use. Physicians must consider not only glycemic control, but also patient preference, concomitant medical conditions, and cost when designing therapeutic regimens.

Abstract
The effects on renal function of moderate restriction in protein intake were studied in 14- to 20-yr-old type I diabetic patients who had no clinical renal disease or hypertension; matched normal subjects served as controls. After assessment of protein intake and renal function, studies were conducted at the completion of each of two consecutive dietary periods of 1 wk. Diets containing 3.5 and 1.5 g X kg-1 X day-1 protein were provided during the first and second periods, respectively. Baseline protein intakes were substantial in both controls (1.86 g X kg-1 X day-1) and diabetics (2.17 g X kg-1 X day-1). Baseline creatinine clearance was increased in diabetics (P = .043). At the end of the high-protein intake period, both diabetics and controls showed similar high values of glomerular filtration rate (GFR) and renal plasma flow (RPF). GFR and RPF decreased markedly (P less than .001) and to a similar degree in both groups after normal protein intake. GFR and RPF in diabetics were not higher than in controls at this point, but filtration fraction was increased in diabetics. Albumin excretion rates were similar in both groups and not influenced by renal function changes. GFR and RPF values correlated significantly with the quantity of protein intake, as estimated from the urea nitrogen appearance rate in both groups. The results suggest that the functional response to variations in protein intake is not altered in the diabetic kidney. In addition, increased renal function in diabetics may be related partly to the excessive protein content in commonly prescribed diabetic diets.(ABSTRACT TRUNCATED AT 250 WORDS)
