Effect of insulin intraperitoneal injection combined with dietary intervention on blood glucose regulation in KKAy mice with spontaneous type 2 diabetes / 国际生物医学工程杂志

Objective:To study the effect of insulin intraperitoneal administration combined with dietary intervention on glycemic regulation in in KKAy mice with spontaneous type 2 diabetes.Methods:An animal model of type 2 diabetes was established, and healthy C57BL/6J mice were selected as the normal control group and healthy KKAy mice as the non-disease group. The successfully modeled KKAy mice were randomly divided into the subcutaneous group, the intraperitoneal group, and the untreated group. The non-disease group was given a maintenance diet, and all other groups were fed a high-fat, high-sugar diet. The daily feeding time was from 08:00 to 20:00, with one feeding at a 4-hour interval, for a total of four times. The subcutaneous and intraperitoneal groups were given subcutaneous and intraperitoneal insulin injections before feeding, and recombinant glargine insulin injection (subcutaneous group: 0.125 IU/g; intraperitoneal group: 0.250 IU/g) was injected before the first feeding, and biosynthetic human insulin injection (subcutaneous group: 0.075 IU/g; intraperitoneal group: 0.125 IU/g) was injected after a 0.5 h interval; the rest 3 times before feeding, the biosynthetic human insulin injection (subcutaneous group: 0.075 IU/g; intraperitoneal group: 0.125 IU/g) was injected for 4 weeks. The dietary intake, body mass, fasting blood glucose, and 1 and 2 h postprandial blood glucose of mice in each group were tested regularly, and an oral glucose tolerance test was performed.Results:The total dietary intake of mice in the intraperitoneal group was lower than that in the subcutaneous group. Compared with the initial body mass, the body mass of the mice in the subcutaneous and intraperitoneal groups decreased by 5.05 and 3.59 g at week 4, respectively. The changes of fasting blood glucose in the subcutaneous and intraperitoneal groups ranged from 5.4 to 9.4 and 5.4 to 6.4 mmol/L, respectively, and the changes of 1 h postprandial blood glucose ranged from 4.6 to 12.3 and 5.7 to 8.9 mmol/L, respectively, and the changes of 2 h postprandial blood glucose ranged from 2.5 to 9.8 and 3.8 to 7.1 mmol/L, respectively. For the glucose tolerance index, the intraperitoneal group showed improvement at all time points, and the subcutaneous group showed a decrease at all time points except for 0 and 60 min.Conclusions:In combination with dietary intervention, insulin intraperitoneal injection was more effective in controlling blood glucose in KKAy mice with spontaneous type 2 diabetes compared with subcutaneous insulin injection, and had a significant improvement in glucose tolerance.

Gut microbiota composition after a dietary and physical activity intervention: a pilot study in Mexican children with obesity / Efecto de una intervención nutricia y de actividad física sobre la composición de la microbiota intestinal: un estudio piloto en niños mexicanos con obesidad

Abstract Background: Gut microbiota is a complex organized collection of microorganisms that confers multiple metabolic advantages to the host. The reduced diversity and proportion of specific gut microbial species have been associated with obesity and metabolic disorders. Multidimensional interventions, including modifications in dietary and physical activity habits, are associated with favorable changes in microbiota composition. This pilot study aimed to evaluate changes in the gut microbiota composition of Mexican children with obesity before and after a 6-week multidimensional intervention. Methods: Blood and stool samples were collected, and anthropometric measurements were obtained from six children with obesity before and after the intervention. The intervention consisted of modeling a hypo energetic diet and giving nutritional and physical activation recommendations. DNA from stool samples was used to characterize gut microbial composition by sequencing the 16S rRNA gene. Results: The decrease in waist circumference was associated with increased Odoribacter relative abundance. However, gut microbiota composition and diversity remained unchanged. Conclusions: Although no modifications in the body mass index, body fat, composition, or diversity of the gut microbiota were observed with the intervention, it was possible to associate the reduction in waist circumference with the presence of Odoribacter after a multidimensional intervention in Mexican children with obesity.

Resumen Introducción: La microbiota intestinal es un conjunto de microorganismos organizados de forma compleja que confieren múltiples ventajas metabólicas al hospedero. La reducida diversidad y la proporción de ciertas especies sobre otras se ha asociado con obesidad y enfermedades metabólicas. Las intervenciones multidimensionales, que incluyen modificaciones en los hábitos alimentarios y de actividad física, se asocian con cambios favorables en la composición de la microbiota. El objetivo de este estudio piloto fue evaluar la composición de la microbiota intestinal de niños mexicanos con obesidad, antes y después de una intervención multidimensional de seis semanas de duración. Métodos: Se tomaron muestras de sangre y de heces y se realizaron las mediciones antropométricas de seis niños con obesidad, antes y después de la intervención. La intervención consistió en modelar una dieta hipoenergética y dar recomendaciones nutricias y de actividad física. A partir del DNA de las muestras de heces se realizó la caracterización de la microbiota intestinal por secuenciación del gen 16S del RNAr. Resultados: La disminución de la circunferencia de cintura se asoció con un aumento en la abundancia del género Odoribacter. Sin embargo, no se encontraron cambios en la composición de la microbiota intestinal. Conclusiones: A pesar de que la intervención no modificó el índice de masa corporal, masa grasa, composición ni diversidad de la microbiota intestinal, sí se logró asociar la reducción de la circunferencia de cintura con la abundancia de Odoribacter en el presente estudio piloto en niños mexicanos con obesidad.

A dietary intervention study on the effects of different dietary structures on postprandial drowsiness / 上海预防医学

ObjectiveTo find the type of dietary structure that can effectively prevent or improve postprandial sleepiness in the Chinese population， and provide scientific basis and solutions for improving or avoiding postprandial sleepiness. MethodsIn this study， a six-day dietary intervention trial was conducted for 20 volunteers on four different diets （normal diet， high-fat diet， high-carbohydrate diet and healthy diet）. ResultsThe results showed that sleepiness increased after all four types of meals， but decreased after 30 minutes in the healthy balanced diet group； meanwhile， it increased for 60 minutes before it declined in the high-carbohydrate， high-fat， and normal diet （control） group. At 60 minutes after meal， the drowsiness of the healthy balanced diet group was the weakest， and that of the high carbohydrate diet groups was the strongest， while that of the normal diet group and the high fat diet group was intermediate （P<0.000 1）. Postprandial sleepiness was positively correlated with intake of carbohydrate and manganese， and negatively correlated with intake of protein， some mineral elements and vitamins. ConclusionThese results suggest that controlling carbohydrate and fat intake and appropriately increasing the intake of mineral elements and vitamins in a healthy and balanced diet can significantly improve and prevent postprandial sleepiness.

Finger millet (Eleusine coracana L.) and white rice diets elicit similar glycaemic response in Asian Indians: Evidence from a randomised clinical trial using continuous glucose monitoring

@#Introduction: Finger millet (FM) or Eleusine coracana L. is considered as a healthier cereal option, especially based on its higher dietary fibre, phytochemical and mineral contents. FM is also recommended for individuals with diabetes, as it is believed to elicit a lower glycaemic response. Methods: The glycaemic response of FM diet was evaluated and compared with white rice (WR) diets using a continuous glucose monitoring system (CGMS™) iPro 2™ among 14 healthy male and female volunteers aged 25-45 years with normal Body Mass Index (≥22.9kg/m2) in a crossover trial. They were recruited from Madras Diabetes Research Foundation volunteers registry. The participants consumed randomised iso-caloric FM or WR based diets for five consecutive days and 24 h interstitial glucose concentrations were recorded. Results: The FM diet had significantly higher dietary fibre than WR (29.9 g vs 15.8 g/1000 kcal, p<0.01) but the other macronutrients were similar. The 5-day average incremental area under the curve (IAUC) of FM diet [Mean (95% CI) = 73.6 (62.1-85.1) mg*min/dl] was not significantly different from that for WR diet [Mean (95% CI) = 78.3(67.9-88.7) mg*min/dl]. Conclusion: Both finger millet and white rice diets showed similar 24 h glycaemic responses, despite the former having higher amounts of dietary fibre. The result suggests that use of FM flour-based food preparations and decorticated FM grains to replace WR in the Indian diets offer no significant benefit with regards to 24 h glycaemic response. Studies of longer duration with larger sample size are needed to verify our findings.

Effect of Aerobic Exercises and Dietary Intervention on Lipid Metabolism in Rats with Metabolic Syndrome and Mechanism Medicated by Peroxisome Proliferator-Activated Receptorα / 中国康复理论与实践

Objective To study the effect of aerobic exercise and dietary intervention on lipid metabolism in metabolic syndrome rats, and investigate the possible mechanism mediated by peroxisome proliferator-activated receptorα(PPARα). Methods After one-week feed-ing, Sprague-Dawley rats were randomly divided into blank control group (CC group) and model group which were feed in high-fat-and-salt diet for 18 weeks to establish a metabolic syndrome model. Then, the metabolic syndrome rats were randomly divided into model control group (MC), the model high-fat diet group (MHE) and the model general died exercise group (ME). ME and MHE groups were forced to run on a treadmill for twelve weeks at the same time. The weight of perirenal fat, blood free fat acid (FFA), and blood lipid were determined. The expression of PPARαmRNA in myocardium was detected by RT-PCR. Western blotting was applied to detect the protein expression of PPARαin myocardium. Results Compared with CC group, MC group showed significant increase in body weight, perirenal fat weigh, FFA, and blood lipid (P<0.05), and significant decrease in PPARαmRNA and protein expression (P<0.01) in myocardium. Compared with MC group, ME and MHE groups showed significant decrease in body weight, perirenal fat weight, triglyceride (TG), and showed significant in-crease in high-density lipoprotein (HDL), and the expression of PPARαmRNA and protein in myocardium (P<0.05). Compared with MHE group, ME group showed decrease in low-density lipoprotein (LDL) (P<0.05), and increase in the expression of PPARαmRNA and protein (P<0.01). Conclusion Aerobic exercise may activate the expression of PPARα, enhance the utilization of fatty acid, reduce body mass and visceral fat mass, improve the dyslipidemia and then regulate lipid metabolism in metabolic syndrome rats.

Phytosterol intensive diet intervention can effectively reduce LDL-C, AST and the blood glucose level of type 2 diabetes patients with NAFLD,improve the positive-to-negative rate of fatty liver.

Dietary primary prevention of allergic diseases in children: the Philippine guidelines

Allergic diseases, such as asthma, allergic rhinitis, eczema, and food allergy, are preventable diseases. Primary prevention strategies of allergic diseases have been in scrutiny. Effective prevention strategies maybe started prenatally, postnatally, during infancy, and even during childhood. These guidelines have been prepared by the Philippine Society of Allergy, Asthma and Immunology and the Philippine Society for Pediatric Gastroenterology, Hepatology and Nutrition. They aim to provide evidence-based recommendations for the dietary primary prevention of allergic diseases in children. The primary audience of these guidelines is all healthcare practitioners who manage patients with potential allergic conditions. These guidelines are based on an exhaustive review of evidences, mostly systematic reviews, randomized controlled trials, and cohort studies. However, there are still many gaps in the evidence of dietary primary prevention of allergic diseases.

Aplication of germ free animals in the research on dietary intervention of gut microbiota / 中国实验动物学报

The effect of dietary intervention on intestinal flora and health has become a research focus in the medi-cal and health field. In terms of development, intestinal flora may become an important target for the study of the influence of dietary styl, health food and traditional Chinese medicine on human health. However, due to the complexity of intestinal flora,high standard for animal models that is applied to researches on the relationship between intestinal flora and dietary in?terference is required. It has been claimed that there is no living microorganisms and parasites inside germ?free animals, thus they are the most widely used basic animal models in the study of intestinal flora. Therefore, it is a common way to ap?ply germ?free animal for generating human flora animal model to study the relationship between diet, flora and health. In this paper we will review the researches and applications of human source flora animal models established by germ?free ani?mals and the influence of dietary intervention on gut microbiota.

Age at onset of caloric restriction and its effects on the redox profile of the rat hippocampus

BACKGROUND: The benefits of caloric restriction (CR) on the protection against age-related neurodegenerative diseases have been the subject of several studies. However, the effects of CR on the central nervous system are still poorl y understood since most studies were carried out in mature animals. The present study aimed to investigate whether the age at onset of CR could differently affect the redox status of the rat hippocampus. METHODS: Thirty-two male Wistar rats at 35 days old (35d;n= 16) and 65 days old (65d;n= 16) were fed ad libitum or subjected to 30 % CR (n= 8 group/age) for 12 weeks. At the end of the experiment, the rats were euthanized, blood was collected, and the hippocampus was dissected for measuring the redox status. RESULTS: CR in 35d and 65d rats induced a 16 and 21% reduction in body weight gain, respectively, compared to controls (p< 0.05). Urea, total cholesterol, triacylglycerol, HDL cholesterol, and LDL cholesterol concentrations were lower in CR 35d rats than in 35d controls (p< 0.05). No differences were detected between the CR groups and controls in the object recognition test (p> 0.05) and in superoxide dismutase activity, nitric oxide content, and lipid peroxidation levels(p> 0.05). However, glutathione peroxidase activity was higher (p< 0.0001) in 65d rats compared to that in 35d rats, and GSH content was higher (p< 0.05) in CR-fed rats compared to that in controls at both ages. CONCLUSIONS: In conclusion, CR increased GSH content when started at both ages but did not affect the activity of antioxidant enzymes and the level of ROS in the hippocampus. In addition, CR did not induce any detrimental effects on memory and nutritional status when started in both 35d and 65d rats

After 6 months, the experimental group′s subjects of TC was (4.28±3.73) mmol/L, the control group was (6.23±1.04) mmol/L, the difference was statistically significant (t = 3.082, P 0.05). Conclusions The new dietary guidance plan can effectively improve and maintain the dietary behavior in hyperlipidemia college teachers, and decrease the blood lipid level.

Six-week Diet Correction for Body Weight Reduction and Its Subsequent Changes of Gut Microbiota: A Case Report

Impact of intestinal microbes on obesity and health is a new topic recently started to get attention. Comparing to the global concern and research trends, there are few research on the association between intestinal bacteria and life style disease in Korean. One voluntary case (female) was reported to show the change in gut microbiota and weight by diet intervention. She was overweight (BMI 23.2 kg/m2) and has abnormal liver function, and the causes of overweight were frequent drinking and meat consumption at the late evening hours. For 47 days, she was administered an improved diet on breakfast and dinner with reduction of meat consumption frequency by 50%. Alcohol consumption was reduced to once a week. As a result, she lost 3 kilograms of body weight. Her fecal sample was collected before and after the intervention, and gut microbiota change was compared using a high-throughput sequencing technique. After diet correction, the shift of gut microbiota was clearly observed with decreased proportion of Firmicutes (from 75.7% to 47.3% in total microbiota) but increased proportion of Bacteroidetes upto 47.7%. After incorporating the diet intervention, it is meaningful to confirm the changes in dominant gut microbiota and weight loss.

Effect of a Worksite-based Dietary Intervention Program for the Management of Metabolic Syndrome / 대한지역사회영양학회지

OBJECTIVES: To investigate the effect of a worksite-based dietary intervention program for the management of metabolic syndrome (MS) among male employees. METHODS: A dietary intervention program combining individual and environmental approach was implemented targeting white-collar employees at a worksite located in Seoul for 10 weeks. Out of 104 employees having agreed to participate in the program, those having three or more out of five components of MS and having two components, including a waist circumference component were classified into "the high risk group" (n=41) and received group nutrition education and individual nutrition counseling three times each. The rest of the study subjects were considered as "the low risk group" (n=63). The food environment at the worksite, where both the high and low risk groups were exposed, was changed to promote healthy eating. Physical data including MS components were collected and a questionnaire on dietary behaviors was administered before and after the intervention. The data from the high risk group (n=17) and the low risk group (n=20), excluding the subjects ineligible for or failed to complete the study (n=67), were analyzed. The difference before and after intervention was tested for significance by Wilcoxon signed-rank tests. RESULTS: Weight, body mass index (BMI), waist circumference, blood pressure, HDL-cholesterol, and HbA1c and the healthy dietary practice score improved significantly after intervention in the high risk group. The median number of MS components decreased significantly from 3.0 to 1.0 in the high risk group. In the low risk group, only HbA1c significantly decreased. Conclusions: The 10-week worksite-based dietary intervention program combining individual and environmental approach was found to be effective for managing MS of male employees. CONCLUSIONS: The 10-week worksite-based dietary intervention program combining individual and environmental approach was found to be effective for managing MS of male employees.

Wine grape pomace flour improves blood pressure, fasting glucose and protein damage in humans: a randomized controlled trial

BACKGROUND: The Mediterranean diet is a healthy diet with positive scientific evidence of preventing chronic diseases. Bioactive components support the healthy properties of the Mediterranean diet. Antioxidants and fiber, two components of the Mediterranean diet, are key functional nutrients for healthy eating and nutrition. Wine grape pomace is a rich source of these dietary constituents and may be beneficial for human health. Our hypothesis was that the intake of red wine grape pomace flour (WGPF) prepared from red wine grapes (Cabernet Sauvignon variety) reduced the metabolic syndrome in humans. To evaluate the effect of WGPF on components of metabolic syndrome we design a 16-week longitudinal intervention study. Thirty-eight males, 30-65 years of age, with at least one component of metabolic syndrome, were randomly assigned to either the intervention group (n = 25) or the control group (n = 13). At lunch, the intervention group was given 20 g of WGPF per day, which contained 10 g of dietary fiber, 822 mg of polyphenols and an antioxidant capacity of 7258 ORAC units. Both groups were asked to maintain their regular eating habits and lifestyles. Clinical evaluation, anthropometric measurements and biochemical blood analyses were done at the beginning and the end of the study. RESULTS: WGPF intake significantly decreased systolic and diastolic blood pressure as well as fasting glucose levels. Plasma γ-tocopherol and δ-tocopherol increased and carbonyl group in plasma protein decreased in WGPT group, significantly. No significant effect was observed for waist circumference, HDL cholesterol, triglycerides, total antioxidant capacity and vitamin C in and between groups. The group-dependent magnitude of the differences between the baseline and final postprandial insulin values and γ-tocopherol concentrations was statistically significant. CONCLUSIONS: The consumption of WGPF-rich in fiber and polyphenol antioxidants, as a food supplement in a regular diet improves blood pressure, glycaemia and postprandial insulin. In addition, increased antioxidant defenses and decreased oxidative protein damage indicating attenuation of oxidative stress. WGPF might be a useful food ingredient for health promotion and chronic disease prevention.

Modificação de uma refeição brasileira com componentes mediterrâneos induz benefícios / Modification of a Brazilian meal including mediterranean components induces cardiometabolic benefits

Introdução: Mudanças na alimentação e atividade física das populações elevaram a incidência de doenças crônicas não-transmissíveis associadas à adiposidade corporal. Este quadro contribui para mortalidade cardiovascular, motivando iniciativas em saúde pública visando à prevenção. Há evidências de que populações que consomem a dieta mediterrânea apresentam menor mortalidade por todas as causas, inclusive cardiovasculares. Os benefícios desta dieta, rica em fibras, gorduras insaturadas e polifenóis, parecem decorrer da atenuação da inflamação, envolvida na gênese de doenças cardiometabólicas. Objetivo: Este estudo investigou os efeitos da modificação de uma refeição diária, o desjejum, de forma a incluir alimentos mediterrâneos, sobre o metabolismo lipídico, glicídico, inflamação subclínica e expressão de genes inflamatórios. Métodos: Foi um ensaio clínico cruzado com duração total de 10 semanas, incluindo 80 adultos com excesso de peso, não-diabéticos. Os participantes passaram por 2 intervenções de 4 semanas no desjejum, com wash-out de 2 semanas entre elas. Os desjejuns, brasileiro e modificado, foram isocalóricos, diferindo quanto ao conteúdo de fibras e tipos de ácidos graxos. Antes e após cada intervenção foi realizado teste de sobrecarga de gorduras (FTT) com refeição rica em gorduras (saturadas e insaturadas MUFA e PUFA, dependendo da intervenção) e coletas sanguíneas seriadas até 240 minutos para determinação de glicose, insulina, lípides e marcadores inflamatórios.

Introduction: Changes in dietary pattern and physical activity of populations have elevated the incidence of chronic non-communicable diseases associated with increased adiposity. Evidence has shown that populations consuming Mediterranean diets have lower mortality from all causes, including cardiovascular diseases. The benefits of this diet rich in fiber and unsaturated fats, derived in part on the effects of these nutrients on inflammatory condition that triggers cardiometabolic diseases. Objective: This study investigated the effects of changing a meal of Brazilian menu, the breakfast, in order to approximate it to the Mediterranean pattern on lipid and glucose metabolism, subclinical inflammation and also on the expression of inflammatory genes. Methods: This study was a crossover trial lasting a total of 10 weeks, including 80 overweight adults, nondiabetic without drug treatment for dyslipidemia. Participants who met the inclusion criteria underwent two 4-week interventions in breakfast, with wash-out of two weeks between them. The breakfasts (Brazilian and modified) were isocaloric, differing according to fiber and types of fatty acids contents. Before and after each intervention, fat tolerance tests with meals rich in fat (saturated and unsaturated depending on the intervention) were perfomed, with blood sample collections for glucose, insulin, lipids and inflammatory markers up to 240 minutes. Also, expression of inflammatory genes before and after each intervention was analyzed.

Objective To explore the effects of traditional Chinese medicine (TCM) five-tone therapy in combination with constitutional types of Chinese medicine based dietary intervention on patients with irritable bowel syndrome (IBS). Methods By convenience sampling, a study was conducted among 68 patients with IBS. The patients were divided into the control group and the intervention group by random digital table method, and each group consisted of 34 patients. Patients in two groups were both treated with conventional drug and routine nursing care, but patients in the intervention group were provided TCM five-tone therapy in combination with constitutional types of Chinese medicine based dietary intervention for 3 months. Patients in two groups were assessed by Chinese Medicine Constitution Questionnaire (CMCQ), Symptom Check List-90 (SCL-90), Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) before treatment and after 12-week treatment. Results After TCM five-tone therapy in combination with constitutional types of Chinese medicine based dietary intervention, the number of IBS patients with pathological constitution types decreased in two groups, the number of patients with gentleness constitution increased to 8 and 25 separately in the control group and intervention group (P<0.05). After intervention, the scores of SAS and SDS in the intervention group were (40.73±8.27)points and (41.16±8.75)points respectively, which were lower than(48.36±7.53)points and(50.03±9.23)points of the control group, and the difference was statistically significant (P< 0.05).

Dietetic Practices in the Management of Childhood Obesity in Malaysia

Introduction: Dietitians play an essential role in the management of childhood obesity and consistency in dietetic practices is required to ensure the effectiveness of treatment. This study assessed dietitians’ current practices in the management of childhood obesity, compared the practices with nutrition practice guidelines used by dietitians in other countries and identified practice components for the development of nutrition practice guidelines for the management of childhood obesity in Malaysia. Methods: A cross-sectional study was conducted among 40 dietitians in 16 Ministry of Health hospitals and three teaching hospitals. Information on current dietetic practices in the management of childhood obesity was obtained through a mailed survey questionnaire. The practices included nutritional assessment, determination of energy requirement, dietary prescription and physical activity modification. Emails were sent to 31 dietetic associations in other countries to obtain information on practice guidelines used by dietitians. Results: Frequently used dietary intervention and physical activity modification approaches were high fibre diet (65%), low fat diet (40%), reduction of sedentary pursuits and screen times (67.5%) and an increase in duration of current physical activities (60%). In comparison to other dietetic practice guidelines, the current dietetic practices in Malaysia do not usually include waist circumference, biochemical and blood pressure data. However, similar to other guidelines, the current dietetic practices included low dietary fat, high fibre diet, decreased sedentary activity and increased physical activity level. Conclusions: The dietetic practices in the management of childhood obesity in Malaysia are diverse. A comprehensive nutrition practice guideline for management of childhood obesity is urgently needed for standardisation of dietetic practices in Malaysia.
