    背景和目的:评估基于数码照片的饮食评估工具的有效性和用户满意度,以替代手写纸质记录方法,在大流行期间为研究人员提供帮助。这项研究比较了基于数码照片的饮食评估工具之间的营养摄入量和用户满意度。被称为NutrinoteGama应用程序,和食物重量作为黄金标准。方法:50名食品与营养专业的大学生(90%为女性;中位年龄,21年)在食用前后拍摄了他们的食物和饮料的照片,然后将其上传到NutrinoteGama应用程序。训练有素的营养学家评估盘子废物,和营养成分显示在NutrinoteGama应用程序上。与基于照片的方法并行,他们保留了体重饮食记录并将其发送给研究人员。使用问卷评估参与者的满意度。结果:在NutrinoteGama(平均值±标准偏差[SD]=582.8±131)和食物称重(平均值±SD=566.1±133)之间的能量摄入测量中未观察到统计学差异(p=0.89)。在蛋白质的测量中也没有观察到统计学差异(p=0.59),脂肪(p=0.434),和碳水化合物(p=230)。能量,蛋白质,脂肪,两种方法估算的碳水化合物摄入量显着相关(r分别为0.86、0.870、0.811、0.738)。超过70%的参与者对基于照片的记录感到满意。结论:结果表明,这种基于数码照片的饮食评估工具是有效且用户友好的,可以估算营养摄入量。
    Background and aim: To evaluate the validity and user satisfaction of a digital photo-based dietary assessment tool as an alternative to the hand-written paper record method that assists researchers during the pandemic. This study compared nutrient intake and users\' satisfaction with methods between a digital photo-based dietary assessment tool, known as the Nutrinote Gama app, and food weighing as the gold standard. Methods: Fifty college students majoring in food and nutrition (90% were women; median age, 21 years) took pictures of their foods and beverages before and after consumption and then uploaded them to the Nutrinote Gama application. Trained nutritionists evaluated plate wastes, and nutritional content was revealed on the Nutrinote Gama application. Parallel to the photo-based method, they kept a weight dietary record and sent it to the researcher. A questionnaire was used to assess participants\' satisfaction. Results: No statistical differences (p = 0.89) were observed in the measurement of energy intake between Nutrinote Gama (mean ± standard deviation [SD] = 582.8 ± 131) and food weighing (mean ± SD = 566.1 ± 133). No statistical differences (p = 0.59) were also observed in the measurement of protein, fat (p = 0.434), and carbohydrate (p = 230). The energy, protein, fat, and carbohydrate intakes estimated from the two methods were significantly correlated (r = 0.86, 0.870, 0.811, 0.738, respectively). Over 70% of participants were satisfied with the photo-based record. Conclusion: The results indicate that this digital photo-based dietary assessment tool is valid and user-friendly to estimate nutrient intake.

    这项研究旨在确定连续三天的能量和营养素摄入量的变化,包括轮班当天,以及轮班前后的日子,在24小时轮班制工作的医护人员中。这项研究是一项观察性随访研究,共有500名志愿者医疗保健专业人员进行。连续3天进行食物消费记录:班前(休息日),轮班日(24小时轮班),和轮班后(休息日)。平均每日能量摄入量,碳水化合物,蛋白质,脂肪,饱和脂肪,咖啡因,维生素B1,B2,烟酸,B6,叶酸,和B12,钾,镁,磷,铁,和锌从最高到最低列出为轮班日>班前>班后(所有成对比较p<0.05)。虽然纤维,维生素C,轮班日和班前日的钙摄入量相似,他们在轮班后的日子显着降低(p<0.05)。轮班后最低的饮食参考摄入量百分比是钙,纤维,还有叶酸,分别。在本研究中,在能量中检测到显著差异,微量营养素摄入,以及轮班前一天之间的大量营养素摄入水平,轮班日,和医护人员下班后的一天。尤其是在24小时轮班后的第一天,应提高对营养素摄入量减少的认识。应该采取适当的预防措施来增加钙,纤维,和叶酸摄入量。
    This study aimed to determine changes in energy and nutrient intakes over three consecutive days, including the day of the shift, and the days before and after the shift, in healthcare workers working in a 24 h shift system. This study is an observational follow-up study conducted with a total of 500 volunteer healthcare professionals. Food consumption records were taken over 3 consecutive days: pre-shift (off day), shift day (24 h shift), and post-shift (off day). Mean daily intakes of energy, carbohydrate, protein, fat, saturated fat, caffeine, vitamins B1, B2, niacin, B6, folate, and B12, potassium, magnesium, phosphorus, iron, and zinc are listed from highest to lowest as shift day > pre-shift > post-shift (p < 0.05 for all pairwise comparisons). While fiber, vitamin C, and calcium intakes were similar on the shift day and pre-shift day, they were significantly lower on the post-shift day (p < 0.05). The lowest dietary reference intake percentages on the post-shift day were calcium, fiber, and folate, respectively. In the present study, significant differences were detected in the energy, micronutrient-intake, and macronutrient-intake levels between the pre-shift day, shift day, and post-shift day of healthcare workers. Awareness should be increased regarding the decreased nutrient intake seen especially on the first day after a 24 h shift, and appropriate precautions should be taken to increase calcium, fiber, and folate intake levels.

    UNASSIGNED: Sports nutrition is an impactful component to sports performance. The purpose of the current study was to investigate the sports nutrition knowledge of National Collegiate Athletic Association collegiate athletes and assess self-reported perceived requirements for energy and macronutrient intake. A secondary aim was to evaluate the awareness of physical and emotional perceptions associated with mindful eating.
    UNASSIGNED: Participants included NCAA Division I (DI, n = 45), II (DII, n = 31), and III (DIII, n = 47) athletes. Athletes completed a validated questionnaire designed to assess sports nutrition knowledge and were asked questions about their perceived dietary energy and macronutrient requirements. Daily energy intake values were calculated using a recommended relative energy intake value of 40, 50, and 60 kcal/kg/day for low, moderate, and high activity levels, respectively. Carbohydrate recommendations were calculated using 4, 6, and 8 g/kg/day, protein recommendations were calculated using relative intakes of 1.4, 1.6, and 1.8 g/kg/day, and fat recommendations were calculated from a relative percentage of total predicted daily energy requirements, equating to 15, 25, and 30% of daily energy. Additionally, athletes completed a questionnaire to assess mindfulness regarding eating habits.
    UNASSIGNED: Overall, athletes answered 45.5 ± 13.5% of questions correctly on the nutrition questionnaire with significant differences observed between male (48.6 ± 13.6%) and female athletes (43.6 ± 13.2%; p = 0.044), as well as significant differences observed between DI athlete scores (38.8 ± 14.1%) and DII athletes (47.7 ± 11.4%; p = 0.002), and DI athletes and DIII athletes (51.71 ± 11.83%; p =  <0.001). All athletes significantly (p < 0.001) underestimated daily energy intake requirements (female, 2,112 ± 575 kcal/day; male, 3,283 ± 538 kcal/day). The mindfulness eating habits total score was significantly higher in male athletes (65.1 ± 6.5) compared to female athletes (60.9 ± 9.5; p = 0.009).
    UNASSIGNED: Division I, II, and III collegiate athletes have poor sports nutrition knowledge, with Division I athletes having exhibited lower scores compared to Division II and III athletes on the sports nutrition knowledge questionnaire. Athletes from all levels of collegiate sports underestimated their energy and macronutrient requirements. Differences in mindful eating habits among female and male athletes were also evident.

    背景:口裂(OFC)是颅面骨骼最常见的先天性畸形。已经尝试将母体饮食的成分关联为OFC的发展或预防的触发因素。
    目的:分析营养状况作为预测亚马逊人群唇腭裂发展的因素。
    方法:对分娩后3个月内的152名母亲进行了访谈比较:51名非综合征性唇腭裂(CLP)患儿的母亲(研究组)和101名非OFC患儿的母亲(对照组)。食物频率问卷用于评估产妇营养,并分析大量和微量营养素对CLP可能的易感性或保护的影响。
    结果:研究组的脂质摄入百分比高于对照组(p=0.01)。在没有OFC家族史的参与者中,研究组的脂质摄入比例较高(p=0.002),蔬菜摄入比例较低(p=0.037).在维生素B2的研究组中,具有阳性家族史的参与者的母亲微量营养素摄入量较低(p=0.03)。B5(p=0.036),E(p=0.03),和叶酸(p=0.022)。
    结论:营养分析表明,较高的母体脂质摄入量增加了后代患有非综合征性CLP的可能性。此外,有OFC病史且母亲叶酸摄入量低的家庭在其后代中显示出非综合征性CLP的风险增加.
    BACKGROUND: Orofacial clefts (OFC) are the most common congenital malformation of the craniofacial skeleton. Attempts have been made to correlate the components of maternal diet as triggers for the development or prevention of OFC.
    OBJECTIVE: To analyze nutritional status as a predictive factor for the development of cleft lip and palate in an Amazonian population.
    METHODS: A total of 152 mothers within 3 months of delivery were interviewed for comparison: 51 mothers of children with nonsyndromic cleft lip and palate (CLP) (study group) and 101 mothers of children without OFC (control group). A food frequency questionnaire was used to assess maternal nutrition and to analyze the influence of macro- and micronutrients on the possible predisposition or protection for CLP.
    RESULTS: The study group showed higher percentage of lipid intake than did the control group (p = 0.01). Among the participants with no family history of OFC, the study group had a higher percentage of lipid intake (p = 0.002) and lower vegetable intake (p = 0.037). Maternal micronutrient intake among the participants with a positive family history was lower in the study group for vitamins B2 (p = 0.03), B5 (p = 0.036), E (p = 0.03), and folate (p = 0.022).
    CONCLUSIONS: Nutritional analysis indicated that higher maternal lipid intake increased the likelihood of having offsprings with nonsyndromic CLP. Moreover, families with a history of OFC and low maternal folate intake showed heightened risk of nonsyndromic CLP in their offsprings.

    脂肪量和肥胖相关(FTO)基因单核苷酸多态性(SNP)干扰影响大量营养素摄入的食物偏好。很少有研究调查这种多态性与微量营养素摄入量的关系。此外,研究表明,肥胖患者缺乏多种微量营养素。这项工作评估了FTOrs9939609基因多态性对患有肥胖的代谢手术女性的饮食营养质量以及大量营养素和维生素的食物摄入量的影响。该研究包括106名女性(24至60岁),BMI为36.1至64.8kg/m2。对当地人口进行了验证的食物频率问卷,以获取有关食物摄入量的信息。营养质量指数(INQ)用于评估大量营养素和维生素摄入量的充足性。能源,与TT相比,年轻年龄组中A等位基因携带者的蛋白质和脂质摄入量较高,但在≥45岁的受试者类别中相似.A等位基因携带者的蛋白质INQ高于TT等位基因携带者。蛋白质的INQs,碳水化合物,维生素B2,B3和B6减少,而维生素C的INQ随着年龄的增长而增加。AA中维生素A的INQ低于TT,不管年龄,而年轻AA的维生素E高于老年AA。年轻女性的维生素B9INQ高于老年女性。总之,FTO基因有助于摄入更多的能量,蛋白质和脂质,并干扰维生素B9,A和E的摄入。除维生素A外,基因型的影响随着年龄的增长而减弱.
    Fat mass and obesity-related (FTO) gene single nucleotide polymorphisms (SNPs) interferes with food preferences that impact macronutrient intake. Few studies have investigated the relationship of this polymorphisms with the intake of micronutrients. Moreover, studies have shown multiple micronutrient deficiencies in patients with obesity. This work evaluated the effect of the FTO rs9939609 gene polymorphism on dietary nutritional quality and food intake of macronutrients and vitamins in of women with obesity candidates for metabolic surgery. The study included 106 women (24 to 60 years old) with BMIs of 36.1 to 64.8 kg/m2. A food frequency questionnaire validated for the local population was applied to obtain information about food intake. The Index of Nutritional Quality (INQ) was used to assess the adequacy of macronutrient and vitamin intake. Energy, protein and lipid intakes were higher in carriers of the A allele compared to TT in the younger age groups but were similar in the class of subjects aged ≥45 years. The INQ for protein was higher in carriers of the A allele than in carriers of the TT allele. The INQs for protein, carbohydrate, vitamins B2, B3 and B6 decreased, whereas the INQ for vitamin C increased with advancing age. The INQ for vitamin A was lower in AA than in TT, regardless of age, whereas vitamin E was higher in younger AA than in older AA. The INQ for vitamin B9 was higher in younger women than in older women. In conclusion, the FTO gene contributed to the intake of more energy, protein and lipids and interfered with the intake of vitamins B9, A and E. With the exception of vitamin A, the effect of the genotype was attenuated with ageing.

    背景:尽管贸易自由化对印度的粮食供应产生了积极影响,地区营养消费的严重不平等仍然存在。关于贸易自由化与营养消费不平等之间关系的经验证据通常提供国家一级的观点,并产生有争议的结果。该研究旨在探讨贸易自由化对印度地区营养消费不平等的影响,并研究对不同营养消费影响的异质性。
    方法:我们的研究利用联合国粮农组织/世卫组织的个人食品消费综合数据,利用基尼系数来衡量2009-2011年印度地区一级2种常量营养素和5种微量营养素的营养消费不平等。通过进口关税作为贸易自由化的代表,因为它的外部强加的性质有助于因果解释。我们使用固定效应模型进一步确定了食品贸易自由化与营养消费不平等之间的直接因果关系。
    结果:结果显示,调查地区超过50%的个体不符合宏量营养素和微量营养素的膳食标准。食品贸易自由化阻碍了营养消费不平等的改善。由于进口关税降低了1%,卡路里摄入量的不平等,锌,维生素B1和维生素B2分别显著增加了0.45、0.56、0.48和0.66,这可能与食品市场表现有关。结果还突出了性别差距的积极作用,女户主家庭,种姓文化对印度营养消费不平等的影响。
    结论:为了减轻自由化的冲击并最大程度地减少其不平等影响,应采取补充措施,例如改善贫困地区的食品物流条件,和营养救济计划。
    BACKGROUND: Despite the positive impact of trade liberalization on food availability in India, severe inequality in nutrition consumption at the district level persists. Empirical evidence on the relationship between trade liberalization and nutrition consumption inequality often offers a country-level perspective and generates disputed outcomes. The study aimed to explore the effects of trade liberalization on inequality in nutrition consumption at the district level in India and to examine the heterogeneity of the impact on different nutrition consumption.
    METHODS: Our study employed the Gini Index to measure nutrition consumption inequality of 2 macronutrients and 5 micronutrients at the district level in India during 2009-2011, utilizing the comprehensive FAO/WHO individual food consumption data. The import tariff was adopted as a proxy for trade liberalization, as its externally imposed nature facilitates a causal interpretation. We further identified the direct causal relationship between food trade liberalization and inequality in nutrition consumption using a fixed effects model.
    RESULTS: The results show that more than 50% of the individuals in the survey districts did not meet the dietary standards for both macronutrients and micronutrients. Food trade liberalization hindered the improvement of inequality in nutrition consumption. As import tariffs were reduced by 1%, the inequality in intake of calories, zinc, vitamin B1, and vitamin B2 increased significantly by 0.45, 0.56, 0.48, and 0.66, respectively, which might be related to food market performance. The results also highlight the positive role of the gender gap, female-headed households, and caste culture on inequality in nutrition consumption in India.
    CONCLUSIONS: To ease the shock of liberalization and minimize its inequality effects, complementary measures should be adopted, such as improving food logistic conditions in poor areas, and nutrition relief schemes.

    探讨早期营养摄入对极早产儿生长发育模式的影响。这是一项观察性研究,包括109名新生儿(<32周孕龄)。围产期发病率,营养治疗(生命的前四周),和体重,长度,和头围(HC)在足月等效年龄的增长进行了评估。生长限制定义为出生和足月年龄测量之间的差异>1.2SD。足月等效年龄的生长限制:52.3%(体重),42.9%(长度),22%(HC)。发病率与营养治疗呈正相关,与总能量供应:蛋白质比呈负相关。肠外营养的持续时间,达到完全肠内喂养的时间,和总能量供应:蛋白质比率显著相关。营养素摄入量影响体重,长度,和HC的增长,累积能量赤字与HC生长受限显著相关。结论:围产期发病会干扰营养治疗和早期营养摄入,导致能量和能量供应不足:蛋白质比例增长。已知:•生命早期大量营养素的摄入量,主要是蛋白质,对预产期婴儿的最佳生长很重要。•发病率的严重程度和低胎龄影响早产儿的营养管理。新增内容:•发病率,反映新生儿临床病程的严重程度,对营养治疗和营养摄入有不利影响。•在生命的第二周,每克蛋白质的能量供应不足与所有生长指标的生长限制显着相关。坚持头围到第四周,强调其测量的重要性,因为这可能是发展风险的早熟迹象。
    To evaluate the influence of early nutritional intake on the growth pattern of very preterm infants. This was an observational study including 109 newborns (< 32 weeks gestational age). Perinatal morbidities, nutritional therapy (first four weeks of life), and weight, length, and head circumference (HC) growth at term-equivalent age were evaluated. Growth restriction was defined as a difference > 1.2 SD between the birth and term age measurements. Growth restriction at term-equivalent age: 52.3% (weight), 42.9% (length), and 22% (HC). Morbidities were positively correlated with nutrition therapy and negatively correlated with the total energy provision: protein ratio. The duration of parenteral nutrition, the time to reach full enteral feedings, and the total energy provision: protein ratio were significantly correlated. Nutrient intake influenced weight, length, and HC growth, and cumulative energy deficit was significantly associated with HC growth restriction.   Conclusion: Perinatal morbidities interfere with nutritional therapy and early nutrient intake, leading to insufficient energy and energy provision: protein ratio for growth. What is Known: • The intake of macronutrients early in life, mainly protein, is important for the optimal growth of pretem infants. • The severity of morbidities and low gestational ages impact the nutritional management of preterm infants. What is New: • The number of morbidities, reflecting the severity of the neonatal clinical course, had a detrimental effect on the nutritional therapy and nutrients intake. • The inadequate energy provision per gram of protein ratio was significantly associated with growth restriction in all growth measures at the second week of life, persisting for head circumference up to the fourth week, highlighting the importance of its measurement, as it could be a precocious sign of development risk.

    常量营养素的摄入可能是青少年认知和神经发育中最有影响力的因素之一。青春期是认知和神经发育的特定时期,在此期间的营养效果可能是终身的。因此,了解大量营养素摄入对青少年认知和神经发育的影响至关重要。因此,我们检查了大量营养素摄入量之间的关联,情报,和神经发育使用基于人群的队列数据。
    我们进行了两项研究。在研究1中,我们总共纳入了1,734名参与者(男孩,907,年龄[平均值±标准偏差]171.9±3.44个月;范围163.0-186.0个月)来自东京青少年队列(TTC),以检查大量营养素摄入量与智商(IQ)之间的关联。在研究2中,我们总共纳入了63名参与者(男孩,38,年龄174.4±7.7个月;范围160.7-191.6个月),使用图论分析从TTC子集衍生的静息状态功能磁共振成像(rs-fMRI)来研究营养摄入对神经发育的影响。
    TTC数据显示,蛋白质摄入量增加的男孩智商较高(β=0.068,p=0.031)。在女孩身上,碳水化合物摄入量减少(β=-0.076,p=0.024)。大约12岁时rs-fMRI的图论分析表明,左额下回的局部效率受损与碳水化合物和脂肪摄入量较高有关([x,y,z]=[-51,23,8],pFDR-分别校正=0.00018和0.02290),而左颞中回中间度中心性的增加与较高的碳水化合物有关,脂肪,和蛋白质摄入量([x,y,z]=[-61,-43,-13],pFDR校正分别=0.0027、0.0029和0.00075)。此外,我们发现,脂肪和蛋白质摄入对左颞中回2年测量间隔内介数中心性变化与智力之间的关系具有显著的调节作用(分别为β=12.41,p=0.0457;β=12.12,p=0.0401).
    我们的研究表明,在青少年早期,大量营养素的摄入与智力相关的神经发育之间存在关联。适当的营养摄入将是健康认知和神经发育的关键因素。
    UNASSIGNED: Macronutrient intake can be one of the most influential factors in cognitive and neural development in adolescents. Adolescence is a specific period of cognitive and neural development, and nutritional effects during this period could be life-long. Therefore, understanding the effects of macronutrient intake on cognitive and neural development in adolescents is crucially important. We thus examined the association across macronutrient intake, intelligence, and neural development using population-based cohort data.
    UNASSIGNED: We conducted two studies. In study 1, we included a total of 1,734 participants (boys, 907, age [mean ± standard deviation] 171.9 ± 3.44 months; range 163.0-186.0 months) from the Tokyo TEEN Cohort (TTC) to examine the association between macronutrient intake and intelligence quotient (IQ). In study 2, we included a total of 63 participants (boys, 38, age 174.4 ± 7.7 months; range 160.7-191.6 months) to investigate the effect of nutrition intake on neural development using graph theory analysis for resting-state functional magnetic resonance imaging (rs-fMRI) derived from a subset of the TTC.
    UNASSIGNED: TTC data revealed that a higher IQ was associated in boys with increased protein intake (β = 0.068, p = 0.031), and in girls, with reduced carbohydrate intake (β = -0.076, p = 0.024). Graph theory analysis for rs-fMRI at approximately age 12 has shown that impaired local efficiency in the left inferior frontal gyrus was associated with higher carbohydrate and fat intake ([x, y, z] = [-51, 23, 8], pFDR-corrected = 0.00018 and 0.02290, respectively), whereas increased betweenness centrality in the left middle temporal gyrus was associated with higher carbohydrate, fat, and protein intake ([x, y, z] = [-61, -43, -13], pFDR-corrected = 0.0027, 0.0029, and 0.00075, respectively). Moreover, we identified a significant moderating effect of fat and protein intake on the relationship between change in betweenness centrality over a 2-year measurement gap in the left middle temporal gyrus and intelligence (β = 12.41, p = 0.0457; β = 12.12, p = 0.0401, respectively).
    UNASSIGNED: Our study showed the association between macronutrient intake and neural development related to intelligence in early adolescents. Appropriate nutritional intake would be a key factor for healthy cognitive and neural development.

    许多流行病学研究已经评估了大量营养素的摄入量以及死亡和心血管疾病(CVD)的风险。然而,目前的证据相互矛盾,需要进一步调查。因此,我们进行了一项综述,以研究和量化膳食常量营养素摄入与CVD发病率和死亡率的潜在剂量-反应关系.来自PubMed的前瞻性队列研究,Embase,中央进行了审查,报告了大量营养素(蛋白质,脂肪,和碳水化合物)与所有原因,CVD,癌症死亡率,或CVD事件。多变量相对风险(RR)进行汇总,并对异质性进行了评估。124项前瞻性队列研究的结果纳入系统评价,101项纳入荟萃分析。在2.2至30年的随访期间,在5,107,821名参与者中发生了506,086例死亡和79,585例CVD事件。高总蛋白摄入量与低CVD发病率相关(RR0.88,95%置信区间0.82-0.94),而高总碳水化合物摄入量与高CVD发病率相关(1.08,1.02-1.13).对于脂肪,高总脂肪摄入量与全因死亡风险降低相关(0.92,0.85-0.99).饱和脂肪酸摄入仅与癌症死亡率相关(1.10,1.06-1.14);单不饱和脂肪酸(MUFA)和多不饱和脂肪酸(PUFA)摄入均与全因死亡率相关(MUFA:0.92,0.86-0.98;PUFA:0.91,0.86-0.96)。这项荟萃分析支持蛋白质摄入与降低CVD发病率的风险有关。而碳水化合物的摄入与CVD发病风险增加有关。高总脂肪摄入量与全因死亡率的低风险相关,在按脂肪类型分层的分析中,这种影响是不同的。
    Many epidemiological studies have evaluated the intake of macronutrients and the risk of mortality and cardiovascular disease (CVD). However, current evidence is conflicting and warrants further investigation. Therefore, we carried out an umbrella review to examine and quantify the potential dose-response association of dietary macronutrient intake with CVD morbidity and mortality. Prospective cohort studies from PubMed, Embase, and CENTRAL were reviewed, which reported associations of macronutrients (protein, fat, and carbohydrate) with all-cause, CVD, cancer mortality, or CVD events. Multivariable relative risks (RR) were pooled, and heterogeneity was assessed. The results of 124 prospective cohort studies were included in the systematic review and 101 in the meta-analysis. During the follow-up period from 2.2 to 30 years, 506,086 deaths and 79,585 CVD events occurred among 5,107,821 participants. High total protein intake was associated with low CVD morbidity (RR 0.88, 95% confidence interval 0.82-0.94), while high total carbohydrate intake was associated with high CVD morbidity (1.08, 1.02-1.13). For fats, a high intake of total fat was associated with a decreased all-cause mortality risk (0.92, 0.85-0.99). Saturated fatty acid intake was only associated with cancer mortality (1.10, 1.06-1.14); Both monounsaturated fatty acid (MUFA) and polyunsaturated fatty acids (PUFA) intake was associated with all-cause mortality (MUFA: 0.92, 0.86-0.98; PUFA: 0.91, 0.86-0.96). This meta-analysis supports that protein intake is associated with a decreased risk of CVD morbidity, while carbohydrate intake is associated with an increased risk of CVD morbidity. High total fat intake is associated with a low risk of all-cause mortality, and this effect was different in an analysis stratified by the type of fat.

    人类从多种选择中选择他们会吃的食物。自助餐厅式饮食与啮齿动物模型的使用增加了我们对多选择食物环境如何影响饮食和健康的理解。然而,能量密度的巨大差异,纹理,和微量营养素的含量,纤维,当人类食品被用来创造啮齿动物自助餐时,蛋白质可能会有解释问题。我们使用定制的啮齿动物自助餐厅饮食(ROD)将这些差异最小化,该饮食的脂肪和糖含量与以前使用的人类食品自助餐厅饮食(HUM)相似。这里,我们使用我们定制的五项食物选择监视器来比较交叉设计中提供ROD和HUM的大鼠的摄入量和进餐模式。与Chow相比,老鼠消耗更多的卡路里,糖,和脂肪和较少的蛋白质和碳水化合物,而选择两种饮食(p<0.05)。虽然HUM和ROD之间的能量摄入相似,回答有差异。老鼠消耗了更多的低脂肪,ROD上的低糖选择与HUM上的营养相似选择相比,导致饮食之间的脂肪和碳水化合物摄入量差异(p<0.05)。在两种选择的饮食中,大量营养素摄入量的稳定性表明,大量营养素的摄入量取决于可用的食物,并受到严格的监管。因此,在解释自助餐厅饮食摄入量时,必须在可用选项的背景下考虑食物选择的性质。
    Humans choose which foods they will eat from multiple options. The use of cafeteria-style diets with rodent models has increased our understanding of how a multichoice food environment affects eating and health. However, the wide variances in energy density, texture, and the content of micronutrients, fiber, and protein can be interpretatively problematic when human foodstuffs are used to create rodent cafeteria diets. We minimized these differences with a custom rodent cafeteria diet (ROD) that varied similarly to a previously used human-foods cafeteria diet (HUM) in fat and sugar content. Here, we used our custom Five-Item Food Choice Monitor to compare the intake and meal patterns of rats offered ROD and HUM in a crossover design. Compared with chow, rats consumed more calories, sugar, and fat and less protein and carbohydrate while on either of the choice diets (p < 0.05). While energy intake was similar between HUM and ROD, there were differences in the responses. Rats consumed more of the low-fat, low-sugar choice on the ROD compared with the nutritionally similar choice on the HUM leading to differences in fat and carbohydrate intake between the diets (p < 0.05). The stability of macronutrient intake while on either choice diet suggests macronutrient intake is determined by the available foods and is strongly regulated. Therefore, interpretative consideration must be given to the nature of food choices in the context of available options when interpreting cafeteria-diet intake.
