- 食品科学 食品科学 食品科学
- 公共卫生 公共卫生
背景情况:
- 过度加工食品 (UPF) 的高摄入量与慢性疾病风险有关.
- 了解UPF对早期饮食质量的影响至关重要.
研究的目的:
- 在美国婴幼儿中使用Nova系统对补充食品和饮料 (CFB) 进行分类.
- 估计Nova食品加工组对能源,营养素和食品组的贡献.
主要方法:
- 从2013-18年NHANES中分析了来自1140名美国婴幼儿 (6-23个月) 的24小时召回.
- 使用加权调查命令来估计Nova组和子组对CFB的贡献 (不包括母乳/公式).
主要成果:
- 美国婴儿和幼儿的CFB能量摄入量中,UPF占45%,而未加工/微加工食品 (U/MPF) 则占42%.
- U/MPF是大多数营养素的主要来源,但UPF是铁 (75%) 和 (48%) 的主要贡献者,其中早餐谷物是主要来源.
- UPF主导了谷物 (总量,整体,精制) 和添加糖 (>80%) 的摄入量,而U/MPF是水果,蔬菜和乳制品的主要来源.
结论:
- U/MPF支持健康的婴儿和幼儿饮食,而UPF提供铁和等必需营养素,但也有助于添加糖等不太理想的成分.
- 需要进一步的研究来完善使用Nova分类来为这个年龄组的饮食指导.

Regulation of Food Intake
289
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...

Parentral Nutrition: Centeral and Peripheral Parental Nutrition
229
Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

Dietary Connections
51.4K
In biological systems, most metabolic pathways are interconnected. The cellular respiration processes that convert glucose to ATP—such as glycolysis, pyruvate oxidation, and the citric acid cycle—tie into those that break down other organic compounds. As a result, various foods—from apples to cheese to guacamole—end up as ATP. In addition to carbohydrates, food also contains proteins and lipids—such as cholesterol and fats. All of these organic compounds are used...

Proteins: Dietary Sources and Requirements
520
Consuming animal-based products offers high-quality proteins that contain optimal levels and combinations of essential amino acids, crucial for tissue repair and growth. Foods like eggs, milk, fish, and most meats are a source of complete proteins. Legumes and cereals are abundant in proteins; however, they typically lack a full range of essential amino acids. As a result, they are considered incomplete protein sources. Some plant sources like soybeans, quinoa, and amaranth do contain complete...

Regulation of the Digestive System
711
Digestive activity regulation hinges on three primary components. Activation is prompted by a multitude of mechanical and chemical indicators, primarily detected by receptors within the stomach and intestines' walls. These receptors predominantly respond to factors such as mechanical stretching of the organ walls, changes in pH and osmolarity, and the presence of digesting materials and their by-products.
The effectors in this regulation system are glands and smooth muscles. Activation of...

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding
209
Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.
