Obesity is a chronic multifactorial disease with associated harms and risks to health, as well as to quality of life and well-being. Currently, approximately 8% of the child and adolescent population suffer from obesity. The objective was to review psychoeducational interventions based on mindful eating for the prevention and management of obesity in youth. A review of the literature was conducted following a narrative approach with a review of different sources. Several databases were consulted (Web of Science [all databases], PsycINFO, Scopus). After searching for psychoeducational interventions based on mindful eating, a total of 15 articles were found, of which 10 were of a preventive nature in the normative child-adolescent population and the rest were aimed at the overweight or obese population or both conditions. The programs that trained mindful eating found behavioral improvements such as an increase in the choice and self-control in the consumption of food, in the identification of biological sensations, improvement in self-concept and well-being. In those interventions aimed at young people with obesity, improvements were obtained in aspects related to mindful eating, self-efficacy in weight control and food-related cravings, and in food control and the regulation of associated emotions. However, a great variety of weaknesses have been detected in the programs, such as the heterogeneity of applied models, use of measures, duration, sample size, lack of protocolization, control groups, or follow-up measures, among others. In conclusion, future lines of mindful eating-based interventions are proposed to extend the results by overcoming the limitations of the studies reviewed.

肥胖是一种慢性多因素疾病，对健康以及生活质量和福祉具有相关危害和风险。目前，大约8%的儿童和青少年患有肥胖症。目的是回顾以正念饮食为基础的心理教育干预措施对青少年肥胖的预防和管理。对文献的回顾是按照不同来源的回顾的叙述方法进行的。参考了几个数据库（Web of Science[所有数据库]、PsycINFO、Scopus）。在搜索了基于正念饮食的心理教育干预措施后，总共发现了15篇文章，其中10篇是针对正常儿童-青少年人群的预防性质，其余的针对超重或肥胖人群或两者兼而有之。训练正念饮食的项目发现了行为上的改善，比如在食物消费方面的选择和自我控制的增加，对生物感觉的识别，自我概念和幸福感的提高。在那些针对肥胖年轻人的干预措施中，在注意饮食、体重控制和食物相关渴望的自我效能、食物控制和相关情绪的调节等方面都得到了改善。然而，在项目中发现了各种各样的弱点，例如应用模型的异质性、度量的使用、持续时间、样本量、缺乏协议化、控制组或后续度量，等等。总之，未来的正念饮食为基础的干预建议线，以扩大结果，克服研究审查的局限性。

There is growing evidence that a proinflammatory diet contributes to the increased risk of sarcopenia by exacerbating low-grade inflammation and insulin resistance, ultimately inducing muscle loss in adults with type 2 diabetes. This study aimed to analyze the association of dietary inflammatory index (DII), physical activity level, and body composition with sarcopenia in adults with type 2 diabetes. The hypothesis of this study was that higher DII increases the risk of sarcopenia. This cross-sectional study was conducted with 249 adults aged 50 years and older with type 2 diabetes who were admitted to the Internal Medicine Department of a tertiary hospital in Türkiye. Nutritional status was determined by 24-hour recall, dietary inflammatory status by energy-adjusted-DII, and physical activity by the International Physical Activity Questionnaire-Short Form. Muscle strength was measured by handgrip dynamometer, body composition analysis was measured by bioelectrical impedance method, and sarcopenia was defined according to EWGSOP-2 criteria. The mean age of the participants was 62.1 ± 6.9 years and the prevalence of sarcopenia was 15.7%. Handgrip strength and appendicular skeletal muscle mass significantly decreased with increasing DII score from tertile 1 to 3 (P < .05). A higher DII score was an independent risk factor for sarcopenia (odds ratio = 2.36, 95% confidence interval: 1.25-4.47, P = .008). This study shows that increased DII was independently associated with sarcopenia in adults with type 2 diabetes after adjustment for potential confounders. Dietary strategies aimed at reducing the potential for inflammation through dietary patterns rich in antioxidants, fiber, and omega-3 fatty acids may be useful in managing the risk of sarcopenia in adults with type 2 diabetes aged 50 years and older.

越来越多的证据表明，促炎饮食通过加剧低度炎症和胰岛素抵抗，最终导致成人2型糖尿病患者肌肉损失，从而增加肌肉减少症的风险。本研究旨在分析成人2型糖尿病患者饮食炎症指数（DII）、身体活动水平和身体成分与肌肉减少症的关系。本研究的假设是较高的DII增加了肌肉减少症的风险。这项横断面研究对249名年龄在50岁及以上的2型糖尿病患者进行了研究，这些患者住进了日本一家三级医院的内科。营养状况通过24小时回忆来确定，饮食炎症状态通过能量调节- dii来确定，身体活动通过国际身体活动问卷-短表来确定。采用握力计测定肌力，采用生物电阻抗法测定体成分，根据EWGSOP-2标准定义肌肉减少症。参与者的平均年龄为62.1±6.9岁，肌肉减少症患病率为15.7%。从第1位到第3位，随着DII评分的增加，握力和尾骨骼肌质量显著降低(P <；. 05)。较高的DII评分是肌少症的独立危险因素（优势比= 2.36,95%可信区间：1.25-4.47,P = 0.008）。本研究表明，在排除潜在混杂因素后，成人2型糖尿病患者体内DII升高与肌肉减少症独立相关。旨在通过富含抗氧化剂、纤维和omega-3脂肪酸的饮食模式来降低炎症的可能性的饮食策略，可能有助于控制50岁及以上2型糖尿病患者肌肉减少症的风险。

Marine n-3 polyunsaturated fatty acids (PUFAs) and seafood intakes have been shown to decrease the risk of metabolic syndrome (MetS), whereas data on related MetS burden in China remain absent. We hypothesize that low marine n-3 PUFAs and seafood consumption are a significant contributor to the burden of MetS in China. The time trend of marine n-3 PUFAs consumption and seafood was evaluated based on the China Health and Nutrition Survey. We used the comparative risk assessment method to estimate the population attributable fraction of MetS cases attributable to the low marine n-3 PUFAs and seafood consumption. We also projected the intakes of marine n-3 PUFAs and seafood and the related MetS burden from 2011 to 2031. The overall intakes of marine n-3 PUFAs (40.4 mg/day) and seafood (32.6 g/day) were far below the optimal level in 2011. The low intakes of marine n-3 PUFAs and seafood were estimated to be responsible for 8.1% and 2.2% of the MetS burden, accounting for 17.0 and 4.6 million MetS cases, respectively, according to the International Diabetes Federation definition in 2011. Although marine n-3 PUFAs and seafood intakes are projected to increase for the next 20 years, the intake levels would still be inadequate and are expected to contribute to 11.3 (marine n-3 PUFAs) and 2.2 (seafood) million MetS cases in 2031. Dietary guidelines should continue to highlight increasing marine n-3 PUFAs and seafood consumption to reduce the MetS burden in China.

海洋n-3多不饱和脂肪酸（PUFAs）和海产品摄入已被证明可降低代谢综合征（MetS）的风险，但中国仍缺乏相关MetS负担的数据。我们假设低海洋n-3 PUFAs和海鲜消费是中国MetS负担的重要贡献者。根据中国健康与营养调查，评价了海洋n-3 PUFAs消费与海产品的时间趋势。我们使用比较风险评估方法来估计由于低海洋n-3 PUFAs和海鲜消费导致的MetS病例的人群归因比例。我们还预测了从2011年到2031年海洋n-3 PUFAs和海产品的摄入量以及相关的MetS负担。海洋n-3 PUFAs （40.4 mg/d）和海产品（32.6 g/d）的总摄入量远低于2011年的最佳水平。根据2011年国际糖尿病联合会（International Diabetes Federation）的定义，海洋n-3 PUFAs和海鲜的低摄入量估计造成了8.1%和2.2%的MetS负担，分别造成了1,700万和460万例MetS病例。尽管预计未来20年海洋n-3 PUFAs和海产品的摄入量将会增加，但摄入水平仍然不足，预计到2031年将导致1130万（海洋n-3 PUFAs）和220万（海产品）MetS病例。饮食指南应继续强调增加海洋n-3 PUFAs和海鲜消费，以减轻中国的MetS负担。

Vitamin E is a potent antioxidant with anti-inflammatory properties and has been proposed as a promising agent in mitigating conditions associated with metabolic syndrome (MetS). We hypothesize that vitamin E is inversely associated with inflammatory biomarkers and low-grade systemic inflammation while showing a direct association with anti-inflammatory biomarkers. Additionally, we hypothesize that vitamin E will also be inversely associated with the risk of developing MetS. This population-based, cross-sectional study used data from the 2015 ISA-Nutrition survey, which included 368 adults and 212 older adults residing in urban São Paulo. Plasma vitamin E concentration was measured using high-performance liquid chromatography, and MetS was diagnosed based on International Diabetes Federation criteria. Biochemical and anthropometric parameters were assessed using standardized protocols. Restricted cubic spline regression models were applied to evaluate nonlinear associations between vitamin E, inflammation, and MetS. In the linear association between IL-6 and vitamin E, there is an interaction with HDL-c. Our findings also revealed a nonlinear J-shaped association between vitamin E and hepcidin (P < .0001), IL-1β (P < .0001), and adiponectin (P < .001), as well as an inverse association with low-grade systemic inflammation (P < .05). Additionally, vitamin E demonstrated a nonlinear association with MetS (P < .01). These results suggest that vitamin E may play a protective role in modulating inflammation and MetS within this specific urban population. Understanding the interactions between vitamin E, inflammation, and MetS risk is essential for developing prevention and dietary management strategies. Future research should explore the underlying mechanisms and assess optimal vitamin E intake to support metabolic health.

维生素E是一种有效的抗氧化剂，具有抗炎特性，被认为是缓解代谢综合征（MetS）相关疾病的有希望的药物。我们假设维生素E与炎症生物标志物和低度全身性炎症呈负相关，而与抗炎生物标志物直接相关。此外，我们假设维生素E也会与患MetS的风险呈负相关。这项以人口为基础的横断面研究使用了2015年isa营养调查的数据，其中包括居住在圣保罗市区的368名成年人和212名老年人。采用高效液相色谱法测定血浆维生素E浓度，并根据国际糖尿病联合会的标准诊断MetS。采用标准化方案评估生化和人体测量参数。限制三次样条回归模型用于评估维生素E、炎症和MetS之间的非线性关联。在IL-6和维生素E之间的线性关联中，存在与HDL-c的相互作用。我们的研究结果还揭示了维生素E和hepcidin之间的非线性j形关联(P <；.0001), IL-1β (P <；.0001)，脂联素(P <；.001)，以及与低度全身性炎症呈负相关(P <；. 05)。此外，维生素E显示出与MetS的非线性关联(P <；. 01)。这些结果表明，维生素E可能在调节这一特定城市人群的炎症和MetS方面发挥保护作用。了解维生素E、炎症和MetS风险之间的相互作用对于制定预防和饮食管理策略至关重要。未来的研究应该探索潜在的机制，并评估最佳的维生素E摄入量，以支持代谢健康。

College students consistently report poor dietary patterns, and face numerous barriers towards improving diet quality. The objective of this study was to determine the impact of an easy-to-learn, semi-personalized diet behavior change intervention on diet quality in college students. This parallel-group, randomized controlled trial was comprised of an ethnically diverse group of full-time college students (N = 114) from two large university campuses in Southern California. Students were screened and excluded if they reported medical conditions requiring a modified diet, were considered at risk for eating disorders, or had a dietary pattern already aligned with the Dietary Guidelines for Americans (DGAs). The experimental group selected 2 of 7 predefined diet change statements that aligned with DGAs and carried them daily as keychain tags for four weeks. The control group was asked to read and consider the DGAs, without any specific dietary directives. We hypothesized that the experimental group would report a significant increase in Healthy Eating Index (HEI)-2020 total and component scores from baseline to 4 weeks, compared to control group. The population ratio method was used to statistically compare HEI-2020 scores between groups. No significant differences were observed between groups for the HEI-2020 total score or its component scores at 4 weeks or at 8 weeks follow-up. This short-term, easy-to-learn dietary intervention for college students was unsuccessful in improving diet quality. Future studies should consider more frequent participant contact and tailoring behavior change options to aspects of students’ diets most in need of improvement. This trial was registered under ISRCTN #53920728.

大学生不断报告不良的饮食模式，在改善饮食质量方面面临许多障碍。本研究的目的是确定易于学习的半个性化饮食行为改变干预对大学生饮食质量的影响。这项平行组随机对照试验由来自南加州两所大型大学校园的不同种族的全日制大学生（N = 114）组成。如果学生报告有需要改变饮食的健康状况，被认为有饮食失调的风险，或者饮食模式已经符合美国人饮食指南（DGAs），则对他们进行筛选和排除。试验组从7个预先设定的饮食改变声明中选择2个与DGAs一致，每天作为钥匙链标签携带，持续四周。对照组被要求阅读和考虑DGAs，没有任何具体的饮食指示。我们假设，与对照组相比，从基线到4周，实验组将报告健康饮食指数(HEI)-2020总分和成分评分显着增加。采用人口比率法对各组间HEI-2020评分进行统计比较。在随访4周或8周时，各组之间的HEI-2020总分或其成分评分均无显著差异。这种针对大学生的短期、易学的饮食干预在改善饮食质量方面并不成功。未来的研究应该考虑更频繁地与参与者接触，并根据学生饮食最需要改进的方面量身定制行为改变方案。该试验在ISRCTN #53920728下注册。

Functional hypothalamic amenorrhea (FHA) is a multifactorial condition caused by psychological stress, energy deficit, weight loss, and excessive physical activity in the absence of adequate energy intake. Nutrition plays a key role in FHA treatment, with the primary intervention focused on correcting energy imbalance. Evidence regarding the exact amount of energy required to restore menses, the timeframe for recovery, and the optimal nutritional practices to support long-term recovery and optimize reproductive outcomes, remain limited. In this review, we aimed to assess if dietary intervention affects the nutritional status, food intake, nutrition knowledge, and hormonal milieu in women with FHA. We performed this review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses method, using the Population, Intervention, Control, Outcome, Study design criteria. A quality appraisal checklist for case series was used. The search included 4 databases and was restricted to English and Italian languages. Eleven articles were included. Five of these referred to the same population analyzed in 2 randomized controlled trials (RCTs); 3 nonrandomized controlled trials (NRCTs); and 1 nonrandomized uncontrolled trial, and 2 case series. Overall, the risk of bias was low for RCTs and moderate-to-high for NRCTs. Menstrual cycle can be restored in 1 to 12 months. One article indicated an additional 350 kcal/d energy intake to achieve this. However, the long-term impact of nutritional intervention alone remains unclear. Further research with a comprehensive, patient-centered approach is needed to confirm these findings and to clarify the possible role of nutritional counseling in FHA treatment.

功能性下丘脑闭经（FHA）是一种多因素疾病，由心理压力、能量不足、体重减轻和在缺乏足够能量摄入的情况下过度运动引起。营养在FHA治疗中起着关键作用，主要干预措施是纠正能量失衡。关于恢复月经所需的确切能量、恢复的时间框架以及支持长期恢复和优化生殖结果的最佳营养做法的证据仍然有限。在这篇综述中，我们旨在评估饮食干预是否会影响FHA女性的营养状况、食物摄入、营养知识和激素环境。我们按照系统评价的首选报告项目和荟萃分析方法，使用人群、干预、对照、结果、研究设计标准进行了本综述。使用了病例系列的质量评估清单。搜索包括4个数据库，仅限于英语和意大利语。纳入了11篇文章。其中5个涉及在2个随机对照试验（rct）中分析的相同人群；3项非随机对照试验（NRCTs）；1个非随机对照试验，2个病例系列。总的来说，随机对照试验的偏倚风险较低，非随机对照试验的偏倚风险中等至高。月经周期1 ~ 12个月即可恢复。一篇文章指出，要达到这一目标，每天需要额外摄入350千卡的能量。然而，仅靠营养干预的长期影响尚不清楚。需要以全面的、以患者为中心的方法进行进一步的研究来证实这些发现，并阐明营养咨询在FHA治疗中的可能作用。

Type 2 diabetes mellitus (T2DM) is a prevalent and multifactorial disease closely linked to overweight. Positive associations between body mass index (BMI) and dysfunctional eating behavior have been observed. However, research specifically examining eating behaviors among individuals with T2DM remains limited. We hypothesized that disordered eating behavior in this population is associated with poorer metabolic control. Thus, this study aimed to investigate the relationship between eating behavior patterns and metabolic control in outpatients with T2DM. In this cross-sectional study, the Three Factor Eating Questionnaire (TFEQ-R21) was administered to 238 outpatients with T2DM. BMI, glycemic control, blood lipids concentration, and blood pressure were examined as outcomes. Eating behavior patterns were identified through cluster analysis based on TFEQ-R21 dimensions. Linear regression models were used to investigate the associations between eating behavior patterns and outcomes, adjusting for age, sex, sedentary lifestyle, and psychiatric medication use. The study was approved by the Hospital's Ethics Committee (ID 2020-0654). Two eating behavior patterns were identified: cognitive restraint (n = 174) and emotional and uncontrolled eating behavior (n = 64). The emotional and uncontrolled eating behavior pattern was associated with higher BMI (b = 2.35; 95% CI = 0.68-4.01), HbA1c (b = 0.54; 95% CI = 0.06-1.01), and triglyceride values (b = 64.42; 95% CI = 16.99-111.86) after adjusting for confounders. In this sample of outpatients with T2DM, the emotional and uncontrolled eating behavior pattern was associated with higher BMI, HbA1c, and triglyceride values as compared to the cognitive restraint eating behavior pattern.

2型糖尿病（T2DM）是一种与超重密切相关的普遍多因素疾病。身体质量指数（BMI）与不正常饮食行为之间存在正相关。然而，专门研究2型糖尿病患者饮食行为的研究仍然有限。我们假设这一人群中饮食失调的行为与较差的代谢控制有关。因此，本研究旨在探讨门诊T2DM患者饮食行为模式与代谢控制之间的关系。在这项横断面研究中，对238例T2DM门诊患者进行了三因素饮食问卷（TFEQ-R21）。研究结果包括BMI、血糖控制、血脂浓度和血压。通过基于TFEQ-R21维度的聚类分析确定饮食行为模式。使用线性回归模型来调查饮食行为模式与结果之间的关系，调整年龄、性别、久坐的生活方式和精神药物的使用。该研究得到了医院伦理委员会（ID 2020-0654）的批准。确定了两种饮食行为模式：认知约束（n = 174）和情绪和不受控制的饮食行为（n = 64）。情绪化和不受控制的饮食行为模式与较高的BMI相关(b = 2.35；95% CI = 0.68-4.01), HbA1c (b = 0.54；95% CI = 0.06-1.01)，甘油三酯值(b = 64.42；调整混杂因素后，95% CI = 16.99-111.86)。在该T2DM门诊患者样本中，与认知约束饮食行为模式相比，情绪性和不受控制的饮食行为模式与较高的BMI、HbA1c和甘油三酯值相关。

Depression is becoming a critical health challenge for the middle-aged and elderly populations. Existing evidence on the associations between body accumulations of advanced glycation end products (AGEs) and depression remain inconsistent. We hypothesized that plasma AGEs concentration might be positively correlated with the incidence of depression in middle-aged and elderly adults. In this cross-sectional study with 586 participants (201 males and 385 females, mean age: 62.18 years old) from Suzhou city, depression was assessed via the Center for Epidemiologic Studies Depression scale 10-item version (CES-D-10). Plasma AGEs of free Nε-carboxymethyl-L-lysine (CML), Nε-(1-carboxyethyl) lysine (CEL), and Nδ-(5-hydro-5-methyl-4-imidazolon-2-yl)-ornithine (MG-H1), as well as protein bound CEL and CML were measured with ultraperformance liquid chromatography and tandem mass spectrometry. Multivariate linear regression analysis and logistic regression analysis were utilized to determine the associations between specific plasma AGEs and CES-D-10 score and the incidence of depression, respectively. The incidence of depression was 8.02%. Plasma protein bound CEL and CML concentration were positively correlated with CES-D-10 score (CEL: β=0.12, P=0.018; CML: β=0.14; P=0.034) in the linear regression analysis. Compared to those below the median concentration of bound CEL and CML, participants with bound CEL and CML concentration above the median had increased risk of depression [ORs (95% CI): 2.33 (1.13-4.84), P=0.023, and ORs (95% CI): 2.27 (1.16-4.43), P=0.016, respectively] in the logistic regression analysis. Elevated plasma bound CEL and CML might be associated with increased risk of depression. Further studies are required to confirm the associations between specific AGEs and the risk of depression.

抑郁症正成为中老年人群面临的重大健康挑战。关于晚期糖基化终产物（AGEs）的体内积累与抑郁症之间关系的现有证据仍然不一致。我们假设血浆AGEs浓度可能与中老年人抑郁症的发病率呈正相关。本研究采用美国流行病学研究中心抑郁量表10题版（CES-D-10）对来自苏州市的586名参与者（201名男性，385名女性，平均年龄：62.18岁）进行抑郁评估。采用超高效液相色谱和串联质谱法测定血浆游离Nε-羧甲基-l -赖氨酸（CML）、Nε-（1-羧乙基）赖氨酸（CEL）和Nδ-（5-氢-5-甲基-4-咪唑啉-2-基）鸟氨酸（MG-H1）的AGEs以及蛋白结合的CEL和CML。采用多元线性回归分析和logistic回归分析分别确定特异性血浆AGEs和CES-D-10评分与抑郁发生率的关系。抑郁发生率为8.02%。血浆蛋白结合CEL和CML浓度与CES-D-10评分呈正相关(CEL: β=0.12， P=0.018；CML:β= 0.14;P=0.034)。在logistic回归分析中，与低于结合型CEL和CML中位数浓度的受试者相比，结合型CEL和CML中位数浓度高于中位数的受试者抑郁风险增加[or (95% CI): 2.33 (1.13-4.84)， P=0.023, or (95% CI): 2.27 (1.16-4.43)， P=0.016]。血浆结合的CEL和CML升高可能与抑郁症风险增加有关。需要进一步的研究来证实特定年龄与抑郁症风险之间的联系。

This study aimed to investigate the associations between serum carotenoid concentrations and all-cause mortality among adults with advanced cardiovascular-kidney-metabolic (CKM) syndrome. Data were analyzed from 1285 adults aged ≥20 years with advanced CKM syndrome (stages 3 or 4), identified from the National Health and Nutrition Examination Survey 2001 to 2006 cohort. Five serum carotenoids were assessed as exposures, including α-carotene, β-carotene, lycopene, lutein/zeaxanthin, and total carotenoids. Cox proportional hazards regression models were used to estimate hazard ratios (HRs) and 95% CIs, while quantile g-computation (Qgcomp) regression was employed to examine the joint effects of all carotenoids. During a median follow-up of 11.8 years, 936 (72.8%) deaths were recorded. Age- and sex-standardized all-cause mortality rates decreased across increasing quartiles of several serum carotenoids, most notably lycopene, for which the mortality rate declined from 106.6 (95% CI: 90.1-123.1) per 1000 person-years in the lowest quartile to 62.4 (95% CI: 54.6-70.1) in the highest quartile. Adjusted for potential confounders, higher concentrations of α-carotene (HR = 0.64, 95% CI: 0.49-0.84), β-carotene (HR = 0.76, 95% CI: 0.61-0.95), lutein/zeaxanthin (HR = 0.75, 95% CI: 0.59-0.96), lycopene (HR = 0.63, 95% CI: 0.49-0.81), and total carotenoids (HR = 0.81, 95% CI: 0.66-1.00) were significantly associated with lower all-cause mortality, while no significant association was observed for β-cryptoxanthin. Qgcomp regression demonstrated a significant joint protective effect of serum carotenoids on all-cause mortality (HR = 0.87, 95% CI: 0.79-0.95, P < .01), with lycopene contributing the most to the overall protective effect. In conclusion, the joint effect of serum carotenoids was independently associated with lower all-cause mortality in adults with advanced CKM syndrome, with lycopene showing the strongest contribution among the 5 carotenoids studied.

本研究旨在探讨成人晚期心血管-肾脏代谢综合征（CKM）患者血清类胡萝卜素浓度与全因死亡率之间的关系。数据分析了1285名年龄≥20岁的晚期CKM综合征（3期或4期）成人，这些数据来自2001年至2006年的国家健康与营养调查队列。五种血清类胡萝卜素被评估为暴露，包括α-胡萝卜素、β-胡萝卜素、番茄红素、叶黄素/玉米黄质和总类胡萝卜素。采用Cox比例风险回归模型估计风险比（hr）和95% ci，采用分位数g计算（Qgcomp）回归检验所有类胡萝卜素的联合效应。在中位11.8年的随访期间，记录了936例（72.8%）死亡。在几种血清类胡萝卜素含量增加的四分位数中，年龄和性别标准化的全因死亡率下降，最明显的是番茄红素，其死亡率从最低四分位数的每1000人年106.6 （95% CI: 90.1-123.1）下降到最高四分位数的每1000人年62.4 （95% CI: 54.6-70.1）。校正潜在混杂因素后，较高浓度的α-胡萝卜素（HR = 0.64, 95% CI: 0.49-0.84）、β-胡萝卜素（HR = 0.76, 95% CI: 0.61-0.95）、叶黄素/玉米黄质（HR = 0.75, 95% CI: 0.59-0.96）、番茄红素（HR = 0.63, 95% CI: 0.49-0.81）和总类胡萝卜素（HR = 0.81, 95% CI: 0.66-1.00）与较低的全因死亡率显著相关，而β-隐黄质则无显著相关性。Qgcomp回归显示血清类胡萝卜素对全因死亡率有显著的联合保护作用(HR = 0.87, 95% CI: 0.79-0.95, P <；.01)，其中番茄红素对整体保护作用的贡献最大。综上所述，血清类胡萝卜素的联合作用与晚期CKM综合征成人全因死亡率的降低独立相关，其中番茄红素在5种类胡萝卜素中贡献最大。

Precision nutrition is emerging as a transformative strategy for optimizing health, particularly in the context of biological aging and chronic disease prevention. This review aims to examine how biological age markers—specifically telomere length and epigenetic clocks—can be integrated into precision nutrition frameworks to personalize interventions, enhance chronic disease management, and support healthy aging. Telomere length is a widely studied biomarker of aging and chronic disease risk, while epigenetic clocks, based on DNA methylation patterns, offer complementary insights into biological age, gene expression, and disease susceptibility. Nutritional interventions rich in antioxidants, omega-3 fatty acids, polyphenols, B vitamins, and anti-inflammatory compounds have shown potential to modulate these biomarkers, supporting cellular health and delaying aging processes. In addition, lifestyle factors such as physical activity, stress management, and adequate sleep play critical roles in maintaining telomere integrity and epigenetic stability. However, challenges remain in translating these biomarkers into clinical practice. Importantly, variability is not the only barrier; most of these biomarkers still lack clinical validation, and there is no consensus on standardized protocols or reference values that would support their routine application in healthcare. Current guidelines recommend combining telomere length and epigenetic age with other molecular markers, such as multi-omics data, within integrative biological age assessment approaches. Nevertheless, translating this approach into clinical practice will require overcoming significant limitations, including the validation of biomarkers, standardization of measurement techniques, cost-effectiveness, and the development of clear clinical guidelines. Continued research is essential to confirm their predictive value and practical utility in precision nutrition strategies aimed at promoting healthy aging and preventing chronic diseases.

精准营养正在成为优化健康的一种变革性战略，特别是在生物衰老和慢性疾病预防的背景下。本综述旨在探讨如何将生物年龄标记-特别是端粒长度和表观遗传时钟-整合到精确营养框架中，以实现个性化干预，加强慢性病管理，并支持健康老龄化。端粒长度是一个被广泛研究的衰老和慢性疾病风险的生物标志物，而表观遗传时钟，基于DNA甲基化模式，提供了对生物年龄，基因表达和疾病易感性的补充见解。富含抗氧化剂、omega-3脂肪酸、多酚、B族维生素和抗炎化合物的营养干预已显示出调节这些生物标志物、支持细胞健康和延缓衰老过程的潜力。此外，生活方式因素，如体育活动、压力管理和充足的睡眠，在维持端粒完整性和表观遗传稳定性方面发挥着关键作用。然而，将这些生物标志物转化为临床实践仍然存在挑战。重要的是，可变性不是唯一的障碍；这些生物标志物中的大多数仍然缺乏临床验证，并且在标准化方案或参考值方面没有达成共识，以支持其在医疗保健中的常规应用。目前的指南建议将端粒长度和表观遗传年龄与其他分子标记相结合，如多组学数据，在综合生物学年龄评估方法中。然而，将这种方法转化为临床实践将需要克服重大限制，包括生物标志物的验证、测量技术的标准化、成本效益和制定明确的临床指南。为了确认它们在促进健康老龄化和预防慢性疾病的精确营养策略中的预测价值和实际应用，继续研究是必不可少的。

This review aims to examine how biological age markers—specifically telomere length and epigenetic clocks—can be integrated into precision nutrition frameworks to personalize interventions, enhance chronic disease management, and support healthy aging. Telomere length is a widely studied biomarker of aging and chronic disease risk, while epigenetic clocks, based on DNA methylation patterns, offer complementary insights into biological age, gene expression, and disease susceptibility. Nutritional interventions rich in antioxidants, omega-3 fatty acids, polyphenols, B vitamins, and anti-inflammatory compounds have shown potential to modulate these biomarkers, supporting cellular health and delaying aging processes. In addition, lifestyle factors such as physical activity, stress management, and adequate sleep play critical roles in maintaining telomere integrity and epigenetic stability. However, challenges remain in translating these biomarkers into clinical practice. Importantly, variability is not the only barrier; most of these biomarkers still lack clinical validation, and there is no consensus on standardized protocols or reference values that would support their routine application in healthcare<strong>.</strong> Current guidelines recommend combining telomere length and epigenetic age with other molecular markers, such as multi-omics data, within integrative biological age assessment approaches. Nevertheless, translating this approach into clinical practice will require overcoming significant limitations, including the validation of biomarkers, standardization of measurement techniques, cost-effectiveness, and the development of clear clinical guidelines. Continued research is essential to confirm their predictive value and practical utility in precision nutrition strategies aimed at promoting healthy aging and preventing chronic diseases.</div></div>","PeriodicalId":19245,"journal":{"name":"Nutrition Research","volume":"140 ","pages":"Pages 135-160"},"PeriodicalIF":3.4,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144703446","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
