Filter by:Strategies to control chronic postprandial hyperglycaemia by optimizing the functionality of foods would strengthen efforts to reduce the risk of developing T2D in the general population. Polyphenolic constituents, may help to delay starch and disaccharide digestion and glucose absorption following a carbohydrate-containing meal or beverage. In vitro studies suggest that some berry anthocyanins and apple polyphenols are effective inhibitors of digestive enzymes, α-amylases and α-glucosidases. Furthermore, polyphenols found in berries and apples inhibit the action of intestinal glucose transporters. Human data is limited; however, randomized controlled trials (RCTs) have shown that berries and apple products reduced postprandial glucose concentrations following consumption of either starch, glucose or sucrose loads. The aim of this study is to test the hypothesis that consumption of a fruit bar containing anthocyanin-rich bilberry and polyphenol-rich apple extracts together with a starch and sucrose meal would reduce the postprandial glycemic response. This study is a randomized cross over study and will aim to recruit 24 overweight (BMI > 25.0), men or post-menopausal women, aged ≥40 and ≤ 70 years who will attend four study sessions. The first study session will be an oral glucose tolerance test (OGTT) and the remaining three will be identical in all respects except for the composition of the fruit bar. Consecutive blood samples will be collected in all 4 study sessions which will be used to measure glucose, insulin, C-peptide, incretins and lipids.
The goal of this proposal is to determine the effect of a high protein diet in which the increase in protein intake is derived from different sources (animal vs plant and protein-rich whole foods vs protein isolates) on: i) liver and muscle insulin sensitivity; ii) the metabolic response to a meal, and iii) 24-h plasma concentration profiles of glucose, glucoregulatory hormones, and protein-derived metabolites purported to cause metabolic dysfunction.
Infusion of glucagon-like peptide 2 (GLP-2) during euglycaemia, hypoglycaemia and hyperglycaemia and evaluation of the effect on glucagon secretion in healthy subjects.
Chronic hepatitis C infection is associated with changes of glucose metabolism end increased frequency of impaired glucose tolerance. This might be a additional risk factor for disease and fibrosis progression. The study aims to evaluate whether a therapy with direct-acting antiviral agents leading to a sustained virologic response directly impacts parameters reflecting glucose metabolism and fibrosis.
Evaluate the effect of a fasting mimicking diet and a food supplement on the microvascular health and urinary heparanase levels in South Asian type 2 diabetic patients with albuminuria.
This study will investigate the effect of high-carbohydrate vs. high-fat overfeeding (130% of energy requirements) on whole body insulin sensitivity. Following habitual diet, participants will be randomly allocated to either a high-carbohydrate or a high-fat diet intervention for 14-days. On days 0, 7 and 14 participants will undergo anthropometric and metabolic testing (primarily an oral glucose tolerance test [OGTT]).
Modern living is associated with an epidemic of type 2 diabetes mellitus (T2DM). Sleep disturbances such as insomnia or frequent awakenings are strong risk factors for T2DM with several studies indicating a central role of melatonin. Additionally, a certain single nucleotide polymorphism in the melatonin receptor gene, MTNR1B rs10830963, with an allele frequency of 30 %, is associated with increased fasting plasma glucose and T2DM. Due to treatment of, among other things, insomnia, the use of melatonin is increasing rapidly in Denmark with a 100-fold increase from 2007-2012 in children and adolescents. No previous studies have thoroughly assessed changes in glucose and fatty acid metabolism after 3 months of melatonin treatment in patients with T2DM.
Background: The relationship between the appearance of insulin resistance phenomena and insufficient or poor-quality sleep is scientifically documented. Objectives: To determine the effectiveness of an intervention based on behavioural techniques on sleep in the nursing consultation in the Primary Care setting to improve the level of HbA1c in patients diagnosed with diabetes mellitus 2 (DM2) or prediabetes. Hypothesis: Patients diagnosed with DM2 or prediabetes with poor sleep quality would improve their HbA1c levels after an intervention on healthier sleep hygiene practices. Sleeping 6 or less hours in adults diagnosed with DM2 or prediabetes would be related to worse metabolic control results. Patients diagnosed with DM2 or prediabetes who would value their sleep as poor quality would have poorer metabolic control. Methodology: Design: Not masked randomized clinical trial. Target population: Patients diagnosed up to the time of DM2 (E11) or prediabetes (R73, R73.9) with age over 18 attending the chronic nurses' follow-up visits of the Basic Health Area of Balaguer in the time range from November 2017 to December 2018. Determinations: Dependent variables: Glycemia and HbA1c. Independent variables: Sex, age, value of the Pittsburgh Sleep Quality Index (PSQI), declared hours of sleep, sleep efficiency, body mass index (BMI), pharmacologic antidiabetic treatment, changes in it, changes in diet, physical exercise and sleep hygiene. Statistical analysis: Analysis of the comparability of the groups and calculation of the confidence interval of the difference in the glycaemic values and HbA1c at the end of the follow-up, with respect to the initiation within the intervention group and within the control, and control group with respect to the group intervention.
The purpose of this study is to investigate the effect of interrupting prolong sedentary behavior with interval exercise on postprandial metabolism following a high fat glucose tolerance test.
The growing prevalence of obesity and type 2 diabetes (T2D) is a major public health problem. Recent studies have clearly established that the gut microbiota plays a key role in the investigator's propensity to develop obesity and associated metabolic health disorders. The gut microbiota compositions plays a decisive role in glucose metabolism and the chronic inflammatory state associated with insulin resistance. Consuming prebiotic rich diet, including polyphenol and inulin rich food could help modulate favorably the gut microbiota which could lead to a reduction of endotoxemia and beneficial metabolic health effects.
