This application requests support for the Nutrition Coordinating Center (NCC) at the University of Minnesota, as a national research resource. NCC develops, provides, and supports state-of-the-art methods and databases related to the collection and analysis of dietary data in studies of diet and health. NCC has the most comprehensive and detailed food and nutrient database appropriate for research purposes. Methodologies, quality control, and training are of the highest quality required for research. The stature of NCC personnel, activities, software, databases, and support services is documented with listings of studies supported, client investigators, letters of support from investigators nationally, and 450 references from the scientific literature that have used NCC methods and databases in their research. Three aims are proposed. Activities for Aim 1 will maintain and update the NCC database of 18,000 foods and 108 nutrients associated with a new interactive, computer-based software system (NDS-R 4.0) to collect, code, and analyze dietary data to generate nutrients consumed. Five additional nutrient fields will be added to the database, and updated versions of the database will be released to clients approximately every nine months so rapid changes in the nation's food supply can be represented. Activities for Aim 2 will enhance the new NDS-R software, and in-house computer programs to maintain the database, to further improve flexibility and save data processing time. Two revised versions of the interview system will be developed and released to clients. Activities for Aim 3 will design, produce, and validate a new methodology and software tool to enable investigators to modify existing food-frequency focused on a certain nutrient. An example of the methodology will be developed for trans fatty acids and validated on a sample of healthy adults. The proposed work will allow NCC to continue to support biomedical research nationally, it will provide continuity and comparability for ongoing and future studies, and it will help control costs to investigators for providing software, databases, and diet-related research services.

此应用程序请求支持营养协调中心 (NCC)在明尼苏达大学，作为国家研究资源。 NCC开发、提供和支持最先进的方法， 与收集和分析饮食数据有关的数据库， 饮食与健康的研究 NCC拥有最全面和详细的 适合研究目的的食物和营养数据库。 方法、质量控制和培训都是最高质量的 研究所需。 NCC人员、活动、 软件、数据库和支持服务用列表记录 支持的研究，客户研究者， 全国范围内的调查人员，以及450篇来自科学界的参考文献， 在研究中使用NCC方法和数据库的文献。 提出了三个目标。 目标1的活动将保持和更新 NCC数据库中有18，000种食物和108种营养素， 新的交互式计算机软件系统（NDS-R 4.0）， 编码，并分析饮食数据，以生成所消耗的营养素。 五 将在数据库中添加其他营养物字段，并进行更新 数据库的版本将大约每隔 九个月以来，国家粮食供应的快速变化可能会 代表。目标2的活动将增强新的NDS-R软件， 和内部计算机程序来维护数据库， 提高灵活性并节省数据处理时间。 两个修订版本 将开发并向客户发布面试系统的详细信息。 目标3的活动将设计、生产和验证一种新的 方法和软件工具，使调查人员能够修改现有的 食物频率集中在某种营养素上。 的示例 将开发反式脂肪酸的方法，并在 健康成年人的样本。 拟议的工作将使NCC能够继续 为了支持全国的生物医学研究，它将提供连续性， 和可比性进行中的和未来的研究，它将有助于 控制研究者提供软件、数据库和 饮食相关的研究服务。
