概括

准确估计食物摄入量需要将食物与营养素数据库相匹配. 这项研究发现,使用完整的饮食研究食品和营养数据库 (FNDDS) 与食品的数字摄影 (DPF) 密切匹配计量食物摄入量.

科学领域:

营养科学营养科学
饮食评估方法饮食评估方法

背景情况:

准确的食物摄入量估计对于营养研究至关重要.
将食物与营养数据库相匹配,例如饮食研究食品和营养数据库 (FNDDS) 是一种常见的方法.
不同的匹配程序可能会影响饮食摄入数据的可靠性.

研究的目的:

评估各种食品匹配程序如何影响FNDDS数据库对食物摄入量的估计.
为了比较来自不同方法的能量摄入估计,包括 PortionSize 应用程序和食品数字摄影 (DPF).

主要方法:

成年参与者使用 PortionSize 应用程序 (包含 FNDDS 代码的子集) 来估计餐点.
实际的食物摄入量是用隐蔽的反权衡方法来测量的.
组合食品通过总结单个营养素值或使用单个复合代码来分析.
评价者使用食品数字摄影 (DPF) 方法与来自 PortionSize 应用程序的食品图像,引用 PortionSize FNDDS 或完整的 FNDDS.

主要成果:

使用 PortionSize FNDDS 的参与者能量摄入量估计相当于评定者的估计.
无论使用 PortionSize FNDDS还是使用完整的 FNDDS,评分员的能量摄入量估计都相似.
使用完整的FNDDS进行的DPF能源估计与重量测量密切结合.
使用单一的FNDDS代码估计组合食品的能量摄入量与总结单个营养素值的估计值不匹配.

结论:

完整的FNDDS与DPF方法相结合,可提供可靠的能量摄入估计,与直接称重相提并论.
对组合食品使用单个复合代码可能导致营养估计不准确.
PortionSize应用程序及其集成的FNDDS子集为估计饮食摄入量提供了一个可行的工具.

Regulation of Food Intake

Regulation of Food Intake

Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
