项目摘要

ABSTRACT/SUMMARY – INTERVENTION CORE Diet is one of the most important determinants of human health and an essential component of population-wide primary prevention strategies. However, there is controversy about the quality and reliability of population- based nutrition research. Indeed, the vast majority of evidence for healthy eating is informed by large studies with dietary patterns assessed via self-report. Self-reported tools have well-recognized limitations. Plasma biomarkers have been a mainstay of epidemiologic studies. Recent advances in metabolomics technology has similarly fostered discovery of metabolites that are highly specific to intakes of foods or food groups. Metabolomics offers a tangible opportunity to identify novel metabolomic signatures for a range of foods and nutrients. However, this progress relies on the tremendous need for controlled feeding studies to identify and validate metabolites specific to each food item and group. Our objective is to establish an Intervention Core, equipped to perform tightly controlled pharmacokinetic and dose-response feeding studies across a range of food items and food groups in diverse populations. We will focus on common foods from the protein and grains food groups: (1) chicken, beef, and soybeans; and (2) whole wheat bread, potatoes, and oats. Based on our collective extensive work in nutrition metabolomics, we hypothesize that acute administration of these foods will have distinct metabolomics signatures that persist over an ensuing 24-hour period. Moreover, plasma concentrations of these metabolites will respond to the amount of the food consumed over a 6-day feeding period. Our long-term goal through these exemplar cases is to establish a rigorous and highly productive resource to the NIH, USDA, and external investigators to systematically catalog specific, reliable, and externally validated metabolomic signatures of nearly all commonly consumed foods in the United States. This proposal combines the nutrition, epidemiology, metabolomics, and feeding trials expertise of investigators at the Harvard T.H.Chan School of Public Health, the Broad Institute of Harvard and MIT, and Harvard Medical School affiliated hospitals to create a state-of-the-art nutrition-metabolomics center that will pave the way for a new era in nutrition research. Building on a long-track record of collaboration, this proposal will contribute novel, objective, metabolomic biomarkers for the characterization of diet in large population- based studies. Ultimately, this proposal answers the NIDDK and USDA’s call “for objective biomarkers of dietary intake that can serve as independent markers of dietary intake and complement current dietary intake assessment methods.”
摘要/摘要--干预核心 饮食是人类健康最重要的决定因素之一,也是整个人口的重要组成部分 初级预防战略。然而,关于人口的质量和可靠性存在争议-- 以营养研究为基础。事实上,绝大多数健康饮食的证据都来自于大型研究 通过自我报告评估饮食模式。自我报告的工具有公认的局限性。 血浆生物标记物一直是流行病学研究的支柱。代谢组学研究进展 同样,技术也促进了对食物或食物摄入量高度特异的代谢物的发现 组。代谢组学为确定一系列新的代谢组学特征提供了一个切实的机会 食物和营养素。然而,这一进展依赖于对控制喂养研究的巨大需求 识别和验证每种食品和组的特定代谢物。 我们的目标是建立一个干预核心,配备以执行严格控制的药代动力学和 对不同人群中的一系列食物和食物组进行剂量-反应喂养研究。我们会 重点关注蛋白质和谷物类食物中的常见食物:(1)鸡肉、牛肉和大豆;以及(2) 全麦面包、土豆和燕麦。基于我们在营养代谢组学方面的集体广泛工作,我们 假设急性服用这些食物将具有持续存在的不同代谢组学特征 在随后的24小时内。此外,这些代谢物的血浆浓度将对 在6天的喂食期内所消耗的食物量。我们的长期目标是通过这些示范案例 是为美国国家卫生研究院、美国农业部和外部调查人员建立严格和高效的资源,以 系统地对几乎所有人的特定、可靠和外部验证的代谢组特征进行分类 在美国经常食用的食物。 这项建议结合了营养、流行病学、代谢组学和喂养试验的专业知识 哈佛大学公共卫生学院、哈佛大学和麻省理工学院博德研究所的研究人员,以及 哈佛医学院附属医院将创建一个最先进的营养代谢组学中心 为营养学研究的新纪元铺平道路。在长期合作记录的基础上,这项提议 将为描述大量人群的饮食特征提供新的、客观的代谢组生物标志物- 基础研究。最终,这项建议回应了NIDDK和美国农业部的呼吁:“寻找客观的生物标记物 可作为膳食摄入量的独立标志并补充当前膳食摄入量的膳食摄入量 评估方法。“
