BACKGROUND AND OBJECTIVESMalnutrition is potentially preventable in older people, but with varied reported prevalence. We assessed its prevalence, assessment methods, and risk factors in older Thai people.METHODS AND STUDY DESIGNStudies published from January 1, 2000, to September 30, 2020 were searched in Medline, EMBASE, Google Scholar, and local databases. A random-effects model was used to calculate pooled prevalence with subgroups analysis (setting of the patient, region). Forest plots displayed sensitivity and specificity for all nutritional screening tools validated against Mini Nutritional Assessment (MNA) with tests for heterogeneity. Publication bias was tested by funnel plot and Egger's test.RESULTS71 studies (total 23,788 subjects) were included where mean age was 65.5 to 78.3 years. The pooled prevalences of malnutrition were 10.4%, 6.1%, and 5.7% by body mass index (BMI), MNA, and MNA-Short Form (MNA-SF), respectively. At-risk of malnutrition prevalence was 42.6% using the MNA and 37.8% using the MNA-SF. The pooled prevalence of malnutrition by BMI <18.5 kg/m2 was 10.4% (95% CI 8.7-12.4). The pooled prevalence of malnutrition based on MNA was 6.1% (95% CI 3.8-9.4). It was highest among hospitalized patients and lowest in community-dwelling elders by both measures. Factors associated with malnutrition were female sex, advanced age, low education, living alone, living in rural areas, comorbidities, eating problems, and geriatric conditions.CONCLUSIONSThe pooled prevalence of elder malnutrition was 6-10%, depending on assessment method and study setting. Hospitalized older people were at increased risk of malnutrition. It might be ameliorated through community directed food systems.
背景和目的营养不良在老年人中是可以预防的,但报告的患病率各不相同。我们评估了其在泰国老年人中的患病率、评估方法和风险因素。方法和研究设计在Medline、EMBASE、Google Scholar和当地数据库中搜索2000年1月1日至2020年9月30日发表的研究。随机效应模型用于通过亚组分析(患者的设置、区域)计算合并患病率。森林图显示了所有营养筛选工具的敏感性和特异性,这些工具通过异质性测试与迷你营养评估(MNA)进行了验证。发表偏倚通过漏斗图和艾格检验进行检验。结果纳入了71项研究(共23788名受试者),平均年龄为65.5至78.3岁。按体重指数(BMI)、MNA和MNA简式(MNA-SF)计算,营养不良的综合患病率分别为10.4%、6.1%和5.7%。使用MNA的营养不良患病率为42.6%,使用MNA-SF的患病率为37.8%。BMI<18.5kg/m2的营养不良合并患病率为10.4%(95%CI 8.7-12.4)。基于MNA的营养不良综合患病率为6.1%(95%CI3.8-9.4)。通过这两项指标,住院患者的营养不良患病率最高,社区老年人的营养不良发病率最低。与营养不良相关的因素包括女性、高龄、低教育程度、独居、农村生活、合并症、饮食问题和老年疾病。结论根据评估方法和研究环境,老年人营养不良的合并患病率为6-10%。住院的老年人营养不良的风险增加。它可能会通过社区指导的食品系统得到改善。

Background and objectives: South Asians are known to have excess adiposity at a lower body mass index, with truncal fat accumulation. Whether this confers higher risk to develop severe COVID-19 is not known. This study evaluated body mass index, body fat mass and waist circumference as risk factors for COVID-19 severity and its progression, in South Asian adults.

Methods and study design: Details of COVID-19 patients (19-90 years) were obtained prospectively, along with weight, height, waist circumference and body fat mass assessed by bioelectrical impedance analysis. Binomial logistic and Poisson regression were performed to test associations between waist circumference, body fat mass and body mass index to evaluate the adjusted OR or relative risk for disease severity at admission and length of stay.

Results: After adjusting for age, sex, height and co-morbidities, body mass index >23 kg/m2 (adjusted OR 2.758, 95% CI 1.025, 7.427), waist circumference (adjusted OR 1.047, 95% CI 1.002, 1.093) and body fat mass (adjusted OR 1.111, 95% CI 1.013, 1.219) were associated with a significant risk for disease severity at admission, while only waist circumference (adjusted relative risk 1.004, 95% CI 1.001, 1.008), and body fat mass (adjusted relative risk 1.011, 95% CI 1.003, 1.018), were associated with a significantly longer length of stay.

Conclusions: Body mass index, at a lower cut-off of >23 kg/m2, is a significant risk factor for COVID-19 disease severity in the group of patients studied. The waist circumference and body fat mass are also good indicators for both severity at admission and length of stay.

背景和目的众所周知,南亚人在较低的体重指数下有过度肥胖,躯干脂肪堆积。这是否会增加患严重新冠肺炎的风险尚不清楚。这项研究评估了南亚成年人的体重指数、体脂肪量和腰围是新冠肺炎严重程度及其进展的危险因素。方法和研究设计前瞻性地获得新冠肺炎患者(19-90岁)的详细信息,以及通过生物电阻抗分析评估的体重、身高、腰围和体脂肪量。采用二项式逻辑回归和泊松回归检验腰围、体脂量和体重指数之间的相关性,以评估入院时疾病严重程度和住院时间的调整OR或相对风险。结果在校正了年龄、性别、身高和合并症后,体重指数>23kg/m2(校正OR 2.758,95%CI 1.025,7.427)、腰围(校正OR 1.047,95%CI 1.002,1.093)和体脂量(校正OR 1.111,95%CI 1.013,1.219)与入院时疾病严重程度的显著风险相关,而只有腰围(调整后的相对风险1.004,95%CI 1.001,1.008)和体脂量(调整后相对风险1.011,95%CI 1.00 3,1.018)与住院时间显著延长有关。结论在研究的患者组中,体重指数(下限>23kg/m2)是新冠肺炎疾病严重程度的重要危险因素。腰围和体脂量也是衡量入院时严重程度和住院时间的良好指标。

BACKGROUND AND OBJECTIVESOverconsumption of drinks containing fructose increases the risk for hyperuricemia and gout. Comparative analysis evaluating the indicators of serum uric acid (SUA) load caused by natural food-derived fructose and pure fructose in sweeteners is lacking. We aimed to uncover the effect of fructose from apple and honey and pure fructose powder on the SUA concentration of healthy young Chinese individuals.METHODS AND STUDY DESIGNTwo randomized crossover trials were performed. The participants were randomly assigned to consume apple or honey (test food) or pure fructose powder (reference food); one week later, the groups' dietary intervention was switched. Blood samples were collected at 0, 30, 60, and 120 min after meal to measure the SUA and blood glucose concentrations.RESULTSAt 30 and 60 min, the SUA concentration in participants consuming apple or honey was lower than in those consuming fructose powder. At 120 min, the SUA concentration of participants consuming apple returned to baseline. The areas under the curve (AUC) within 2 h (2h- AUCs) of SUA exhibited the trend of fructose >honey >apple. The 2h-AUC ratio between test food and reference food was determined using the uric acid index to assess the efficiency of food-derived fructose in increasing the SUA concentration. The uric acid index of honey was higher than that of apple. Men had higher postprandial SUA concentration than women.CONCLUSIONSFood-derived fructose caused a lighter load on uric acid metabolism than pure fructose. Uric acid index can be useful for distinguishing fructose-containing foods.
背景与目的过量饮用含有果糖的饮料会增加患高尿酸血症和痛风的风险。缺乏评估甜味剂中天然食品衍生果糖和纯果糖引起的血清尿酸(SUA)负荷指标的比较分析。我们旨在揭示苹果和蜂蜜中的果糖以及纯果糖粉对健康中国年轻人SUA浓度的影响。方法和研究设计进行两项随机交叉试验。参与者被随机分配食用苹果或蜂蜜(测试食品)或纯果糖粉(参考食品);一周后,两组改变了饮食干预。在餐后0、30、60和120分钟采集血样,以测量SUA和血糖浓度。结果在30和60分钟时,食用苹果或蜂蜜的参与者的SUA浓度低于食用果糖粉的参与者。在120分钟时,食用苹果的参与者的SUA浓度恢复到基线。SUA作用2h内的曲线下面积(AUC)呈果糖>蜂蜜>苹果的趋势。使用尿酸指数测定试验食品和参考食品之间的2h AUC比率,以评估食品衍生果糖在增加SUA浓度方面的效率。蜂蜜的尿酸指数高于苹果。男性餐后SUA浓度高于女性。结论:与纯果糖相比,食物来源的果糖对尿酸代谢的影响较小。尿酸指数可用于区分含果糖的食物。

BACKGROUND AND OBJECTIVESThis study aimed to evaluate the effects of enteral immunonutrition (EIN) on the nutritional status of patients during the perioperative period of digestive system surgery.METHODS AND STUDY DESIGNThe clinical data of 102 patients who underwent gastrointestinal surgery between August 2017 and February 2021 were retrospectively analyzed. According to the nutritional support regimen, the patients were divided into an enteral nutrition (EN) group (50 patients) and an EIN group (52 patients).RESULTSThe times (in hours) to return of the first bowel sound, first postoperative flatus, and first bowel movement, as well as the length of postoperative hospital stay were shorter in the EIN group than in the EN group (p<0.05). The concentrations of hemoglobin, prealbumin, albumin, and transferrin, as well as the concentrations of immunoglobulin A (IgA), immunoglobulin G (IgG), immunoglobulin M (IgM), complement C3, and complement C4 were higher in the EIN group than in the EN group at 1 and 7 days after surgery (p<0.05). The concentrations of endotoxins, D-lactic acid, and diamine oxidase were lower in the EIN group than in the EN group (p<0.05). The tolerance to enteral feeding was better in the EIN group than in the EN group (p<0.05). The incidence of complications was lower in the EIN group (5.77%) than in the EN group (10.0%) (p>0.05).CONCLUSIONSEIN can promote gastrointestinal function recovery, improve the nutritional status, enhance the humoral immune function, regulate intestinal flora balance, improve intestinal permeability, prevent enteral feeding intolerance, and reduce complications in patients undergoing surgery for digestive system diseases.

BACKGROUND AND OBJECTIVESInflammatory cytokines and metabolic abnormalities are common in patients with tuberculosis. Observational studies have indicated that probiotics modulate inflammatory cytokines and metabolites; however, clinical evidence of the effect of probiotics on patients with tuberculosis is lacking. This study investigated the effects of Lactobacillus casei on inflammatory cytokines and metabolites during tuberculosis treatment.METHODS AND STUDY DESIGNA randomized controlled trial was conducted. A total of 47 inpatients were included and randomly assigned to receive standard antituberculosis therapy only (control group) or that treatment together with 1 × 1010 colony-forming units per day of Lactobacillus casei (low-dose group) or 2 × 1010 colony-forming units per day of Lactobacillus casei (high-dose group) for 4 weeks of intensive treatment during hospitalization. Plasma samples were analyzed for inflammatory cytokines and metabolomics with ELISA kits and ultrahigh performance liquid chromatography quadrupole time-of-flight mass spectrometry.RESULTSDaily Lactobacillus casei supplementation of up to 2 × 1010 colony-forming units significantly lowered the concentrations of tumor necrosis factor-α, interleukin-6, interleukin-10, and interleukin-12 (p=0.007, p=0.042, p=0.002, p<0.001, respectively) in patients with tuberculosis. Compared with the control and low-dose groups, the plasma metabolites of phosphatidylserine, maresin 1, phosphatidylcholine, L-saccharopine, and pyridoxamine were significantly upregulated, and N-acetylmethionine, L-tryptophan, phosphatidylethanolamine, and phenylalanine were downregulated in the high-dose group. Strong correlations were observed between metabolites and inflammatory cytokines.CONCLUSIONSLactobacillus casei supplementation during the intensive phase of tuberculosis treatment can significantly modulate inflammatory cytokines and metabolites. Decreased inflammatory cytokines may be related to metabolite changes.
背景与目的炎症细胞因子和代谢异常在肺结核患者中很常见。观察研究表明,益生菌调节炎性细胞因子和代谢产物;然而,益生菌对肺结核患者疗效的临床证据尚缺乏。本研究探讨了干酪乳杆菌在结核病治疗过程中对炎性细胞因子和代谢产物的影响。方法与研究设计采用随机对照试验。共有47名住院患者被纳入并随机分配接受标准抗结核治疗(对照组),或在住院期间接受每天1×1010个菌落形成单位的干酪乳杆菌(低剂量组)或每天2×1010个集落形成单位的酪蛋白乳杆菌(高剂量组)的强化治疗4周。用ELISA试剂盒和超高效液相色谱-四极飞行时间质谱法分析血浆样品的炎性细胞因子和代谢组学。结果每日补充2×1010菌落形成单位的干酪乳杆菌可显著降低肺结核患者的肿瘤坏死因子-α、白细胞介素-6、白细胞白细胞介蛋白-10和白细胞介因子-12的浓度(分别为p=0.007、p=0.042、p=0.002、p<0.001)。与对照组和低剂量组相比,高剂量组的磷脂酰丝氨酸、马雷蛋白1、磷脂酰胆碱、L-糖固酶和吡哆胺的血浆代谢产物显著上调,N-乙酰甲硫氨酸、L-色氨酸、磷脂酰乙醇胺和苯丙氨酸下调。代谢产物和炎性细胞因子之间存在很强的相关性。结论在结核病强化治疗期间补充干酪乳杆菌可显著调节炎性细胞因子和代谢产物。炎性细胞因子的减少可能与代谢产物的变化有关。

Compared with the control and low-dose groups, the plasma metabolites of phosphatidylserine, maresin 1, phosphatidylcholine, L-saccharopine, and pyridoxamine were significantly upregulated, and N-acetylmethionine, L-tryptophan, phosphatidylethanolamine, and phenylalanine were downregulated in the high-dose group. Strong correlations were observed between metabolites and inflammatory cytokines.\u0000\u0000\u0000CONCLUSIONS\u0000Lactobacillus casei supplementation during the intensive phase of tuberculosis treatment can significantly modulate inflammatory cytokines and metabolites. Decreased inflammatory cytokines may be related to metabolite changes.","PeriodicalId":8486,"journal":{"name":"Asia Pacific journal of clinical nutrition","volume":"31 1 1","pages":"66-77"},"PeriodicalIF":1.3,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45073667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

BACKGROUND AND OBJECTIVESThe present study aimed to investigate the hypothesis that dietary amino acid intakes are associated with the risk of sarcopenia through a community-based observational study.METHODS AND STUDY DESIGNA total of 1,140 participants (72.7±6.3 y) were recruited from an annual health check-up program in Qingdao, China. Skeletal muscle mass, muscle mass functions and biochemical parameters were measured by standard methods. Dietary intake was assessed by 3-day, 24-hour food records. The odds ratios (ORs) and 95% confidence intervals (CIs) of sarcopenic risk across quartiles of amino acid intakes were calculated using a multivariable- adjusted logistic regression model. Generalized linear models were used to assess the associations between dietary amino acid intakes and muscle mass functions.RESULTSThe prevalence of sarcopenia was 4.1%. Compared with the lowest category intake, the highest category of branched chain amino acids (BCAAs) (OR=0.11; 95% CI: 0.01, 0.90; p for trend=0.119), isoleucine (OR=0.11; 95% CI: 0.01, 0.89; p for trend=0.122) and tryptophan (OR=0.10; 95% CI: 0.01, 0.87; p for trend=0.176) was negatively correlated with sarcopenic risk with adjustment for potential confounding factors. Generalized linear model analysis showed that gait speed was positively correlated with dietary intakes of lysine, threonine, leucine, valine, tryptophan, BCAAs and aromatic amino acids (p<0.05).CONCLUSIONSHigher intakes of BCAAs were associated with a lower risk of sarcopenia, which might beneficially protect against sarcopenia and improve physical function of the elderly.
背景和目的本研究旨在通过一项基于社区的观察性研究来调查饮食氨基酸摄入与少肌症风险相关的假设。方法和研究设计从中国青岛的年度健康检查项目中招募了1140名参与者(72.7±6.3y)。采用标准方法测定骨骼肌质量、肌肉质量功能和生化参数。通过3天24小时的食物记录来评估饮食摄入量。使用多变量调整的逻辑回归模型计算氨基酸摄入量四分位数的肌萎缩风险的比值比(OR)和95%置信区间(CI)。使用广义线性模型来评估膳食氨基酸摄入量与肌肉质量功能之间的关系。结果少肌症的患病率为4.1%。与最低类别摄入量、最高类别支链氨基酸(BCAAs)相比(OR=0.11;95%CI:0.01,0.90;趋势p=0.119),异亮氨酸(OR=0.11;95%可信区间:0.010.89;趋势p=0.122)和色氨酸(OR=0.10;95%可信范围:0.010.87;趋势p=0.176)与肌萎缩风险呈负相关,并对潜在的混杂因素进行了调整。广义线性模型分析表明,步态速度与赖氨酸、苏氨酸、亮氨酸、缬氨酸、色氨酸、支链氨基酸和芳香族氨基酸的摄入量呈正相关(p<0.05)。

BACKGROUND AND OBJECTIVESEnergy provided by macronutrients plays a key role in healthy aging. This study therefore explored the association between macronutrients and cognitive function in elderly populations in rural areas of Qingdao, China.METHODS AND STUDY DESIGNThis study included 1,504 participants over the age of 65 recruited from Licha Town, Qingdao City, China. Dietary intake was measured using the Food Frequency Questionnaire, and cognitive function was assessed using the Mini-Mental State Examination. Logistic regression models were used to evaluate the association between dietary macronutrient intake and cognitive function. In addition, restricted cubic bars were applied to determine the dose-response relationship between macronutrient ratios and cognitive performance.RESULTSA total of 877 adults over the age of 65 were included. After adjusting the weighted multiple variables, significant positive associations were revealed between protein and moderate carbohydrate intake and cognitive ability, but a negative association between fat intake and cognitive performance was identified. After calculating the daily energy supply ratio, similar associations were revealed between fat and protein intake and cognitive function. Furthermore, the ratio of proteins to carbohydrates had a U-shaped relationship with cognitive function (pnonlinearity=0.674), whereas the ratio of proteins to fats was L-shaped with lower cognitive function (pnonlinearity<0.001). Compared with the lowest quartile of the ratio of protein to fat intake, the weighted adjusted OR (95% CI) of the highest quartile was 0.509 (0.314, 0.827) for low cognitive performance.CONCLUSIONSWith an adequate carbohydrate supply, appropriately increasing dietary protein intake and reducing fat intake might benefit the cognitive function of elders in rural areas.
背景与目的大量营养素提供的能量在健康衰老中起着关键作用。因此,本研究探讨了中国青岛农村老年人群中常量营养素与认知功能之间的关系。方法与研究设计本研究包括1504名来自中国青岛市李岔镇的65岁以上参与者。使用食物频率问卷测量饮食摄入量,并使用迷你精神状态检查评估认知功能。采用Logistic回归模型评估膳食常量营养素摄入与认知功能之间的关系。此外,应用限制性立方条来确定常量营养素比率与认知表现之间的剂量-反应关系。结果共纳入877名65岁以上的成年人。在调整加权多变量后,蛋白质和适度碳水化合物摄入与认知能力之间存在显著的正相关,但脂肪摄入与认知表现之间存在负相关。在计算每日能量供应比率后,脂肪和蛋白质摄入与认知功能之间的相关性相似。此外,蛋白质与碳水化合物的比率与认知功能呈U型关系(pnlinearity=0.674),而蛋白质与脂肪的比率呈L型,认知功能较低(pnlineality<0.001),对于低认知表现,最高四分位数的加权调整OR(95%CI)为0.509(0.314、0.827)。结论在充足的碳水化合物供应下,适当增加膳食蛋白质摄入量和减少脂肪摄入量可能有利于农村老年人的认知功能。

BACKGROUND AND OBJECTIVESTo evaluate the significance of diaphragm thickness (DT) in assessing the nutritional status and predicting the length of hospital stay (LOS) of patients with COVID-19.METHODS AND STUDY DESIGNThe data of 212 patients with severe and critical COVID-19 in Wuhan, China, were retrospectively analyzed. Computed tomography (CT)-obtained DT was measured in cross-sectional images of the mediastinal window at the level of the outlet of the celiac trunk at admission and at 2 weeks, then the rate of change in DT(RCDT) at 2 weeks was calculated. Nutritional risk and malnutrition were evaluated at admission.RESULTSA total of 91 patients were involved in the study. The mean DT was 3.06±0.58 mm (3.15±0.63 mm in male and 2.93±0.50 mm in female). DT was significantly negatively correlated with malnutrition based on Global Leadership Initiative on Malnutrition (GLIM) criteria (r=-0.324, p=0.002), Nutritional Risk Screening 2002 (NRS-2002) score (r=-0.364, p=0.000) and the Malnutrition Universal Screening Tool (MUST) score (r=-0.326, p=0.002) at admission. For the prediction of LOS ≥4 weeks in patients with COVID-19, the area under the ROC curve (AUC) of the RCDT at 2 weeks was 0.772, while the AUCs of DT, NRS-2002, MUST and Nutrition Risk in Critically Ill scores at admission were 0.751, 0.676, 0.638 and 0.699 respectively. According to the model of multiple linear regression analysis, the DT at admission (β=-0.377, p=0.000), RCDT at 2 weeks (β =-0.323, p=0.001), and mechanical ventilation (β=0.192, p=0.031) were independent risk factors contributed to LOS.CONCLUSIONSCT-obtained DT can be used as a dynamic assessment tool for evaluating the nutritional status of patients in isolation wards for COVID-19.

Nutrition was invented in the early 19th century as a biochemical science that reduces foods into significant chemical constituents. Ever since then, the teaching and practice of nutrition has been based on this conceptual framework, or paradigm. The examples given here are dietary guidelines and other food guides. The first guides issued up to the middle of the last century were designed to help prevent nutrient deficiencies, promote growth, and ensure plentiful diets. These recommended foods then thought to contain adequate proteins, fats, carbohydrates, vitamins, minerals and trace elements, as well as dietary energy. At a time of accelerating industrial production of food, they were generally effective. Within the second half of the century, guides were developed and changed to counter the rapid rise in heart disease in the USA, the UK, and other high-income countries. These recommended less foods of all types high in fat, saturated fat, cholesterol and sodium, more 'complex carbohydrates', and fruit and vegetables rich in microconstituents. They probably had some limited effect. In this century and now, dominant guides have been changed again in attempts to counter what has become pandemic obesity and diabetes. These recommend less food high in saturated fat, sugar and sodium, with less emphasis on total fat and more on sugar. They are not effective. All these guides are derived from and governed by the biochemical paradigm of nutrition science. This was once useful, but now should be discarded as obsolete except for addressing deficiencies. Here, a new paradigm is proposed.
营养发明于19世纪初,是一门将食物转化为重要化学成分的生物化学科学。从那时起,营养学的教学和实践就建立在这个概念框架或范式的基础上。这里给出的例子是饮食指南和其他食物指南。上世纪中叶发布的第一批指南旨在帮助预防营养缺乏,促进生长,并确保充足的饮食。这些推荐的食物被认为含有足够的蛋白质、脂肪、碳水化合物、维生素、矿物质和微量元素,以及膳食能量。在食品工业生产加速的时代,它们通常是有效的。在本世纪下半叶,美国、英国和其他高收入国家制定并修改了指南,以应对心脏病的快速上升。这些建议减少所有类型的高脂肪、饱和脂肪、胆固醇和钠的食物,更多的“复合碳水化合物”,以及富含微量成分的水果和蔬菜。它们可能产生了一些有限的影响。在本世纪和现在,为了应对已经成为流行病的肥胖和糖尿病,主导指南再次发生了变化。这些建议减少饱和脂肪、糖和钠含量高的食物,减少对总脂肪的重视,增加对糖的重视。它们并不有效。所有这些指南都源于营养科学的生物化学范式,并受其支配。这曾经是有用的,但现在除了解决不足之外,应该被视为过时。在此,提出了一种新的范式。

BACKGROUND AND OBJECTIVESThe variation in glycemic responses to white rice caused by the circadian rhythm has been widely investigated but remain controversial. This study investigated diurnal differences in the effect of rice meals on glycemic responses, insulin responses, satiety, and acute cognitive function.METHODS AND STUDY DESIGNA total of 20 healthy participants in Group 1 and 14 in Group 2 were served identical servings of cooked white rice containing 50 g of available carbohydrates at 8:00 a.m. (rice at breakfast), 12:30 p.m. (rice at lunch), and 5:00 p.m. (rice at early supper) in a randomized order. Postprandial blood glucose, insulin, satiety, and cognitive performance tests were conducted for each test meal.RESULTSThe rice at an early supper elicited significantly milder glycemic responses than did the rice at lunch and resulted in a lower insulin sensitivity than did rice at breakfast. No difference was observed among the test meals in terms of hunger and prospective food intake. Diurnal acute cognitive performance did not differ considerably among the meals. A correlation analysis indicated that low variability in glycemic responses was positively associated with superior cognitive performance.CONCLUSIONSA high-glycemic index white rice supper at 5:00 p.m. may facilitate daily glycemic management.
背景和目的昼夜节律引起的白米饭血糖反应的变化已被广泛研究,但仍存在争议。这项研究调查了米粉对血糖反应、胰岛素反应、饱腹感和急性认知功能影响的昼夜差异。方法和研究设计第1组共20名健康参与者和第2组共14名健康参与者在上午8:00(早餐米饭)、下午12:30(午餐米饭)和下午5:00(早晚餐米饭)随机食用相同份量的含有50g可用碳水化合物的熟白米。对每顿测试餐进行餐后血糖、胰岛素、饱腹感和认知能力测试。结果:早晚餐时吃米饭比午餐时吃米饭引起的血糖反应明显温和,并导致胰岛素敏感性比早餐时吃米饭低。在饥饿感和预期食物摄入量方面,试验餐之间没有观察到差异。不同膳食的日间急性认知表现没有显著差异。相关分析表明,低血糖反应的低变异性与较高的认知能力呈正相关。结论下午5:00的高血糖指数白米晚餐可能有助于日常血糖管理。

This study investigated diurnal differences in the effect of rice meals on glycemic responses, insulin responses, satiety, and acute cognitive function.\u0000\u0000\u0000METHODS AND STUDY DESIGN\u0000A total of 20 healthy participants in Group 1 and 14 in Group 2 were served identical servings of cooked white rice containing 50 g of available carbohydrates at 8:00 a.m. (rice at breakfast), 12:30 p.m. (rice at lunch), and 5:00 p.m. (rice at early supper) in a randomized order. Postprandial blood glucose, insulin, satiety, and cognitive performance tests were conducted for each test meal.\u0000\u0000\u0000RESULTS\u0000The rice at an early supper elicited significantly milder glycemic responses than did the rice at lunch and resulted in a lower insulin sensitivity than did rice at breakfast. No difference was observed among the test meals in terms of hunger and prospective food intake. Diurnal acute cognitive performance did not differ considerably among the meals. A correlation analysis indicated that low variability in glycemic responses was positively associated with superior cognitive performance.\u0000\u0000\u0000CONCLUSIONS\u0000A high-glycemic index white rice supper at 5:00 p.m. may facilitate daily glycemic management.","PeriodicalId":8486,"journal":{"name":"Asia Pacific journal of clinical nutrition","volume":"31 1 1","pages":"57-65"},"PeriodicalIF":1.3,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49217094","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
