概括
一个以食物为基础的干预措施改善了学龄前儿童的水果和蔬菜 (FV) 消费,通过皮肤胡卜素状况 (SCS) 来衡量. 虽然这两组都显示出增长,但干预组的SCS的百分比增加更高.
科学领域:
- 营养科学 营养科学
- 儿科健康 儿科健康
- 行为科学 行为科学
背景情况:
- 幼儿园儿童的水果和蔬菜 (FV) 摄入量通常很低.
- 通过皮肤胡卜素状况 (SCS) 来测量FV消耗提供了一个客观的生物标志物.
- 基于食物的学习 (FBL) 是一种改善幼儿期饮食习惯的潜在策略.
研究的目的:
- 为了评估基于食物的干预对学龄前儿童的FV消费的有效性.
- 用皮肤胡卜素状况 (SCS) 作为生物标志物来评估FV摄入量的变化.
- 探索FBL与增强的FV接入相结合的影响.
主要方法:
- 一项涉及北卡罗来纳州7个中心183名Head Start儿童的准实验性研究.
- 干预课堂 (ICs) 接受了以食物为基础的学习计划;比较课堂 (CC) 接受了标准课程.
- 皮肤胡卜素状况 (SCS) 在基线,干预前和干预后使用Veggie Meter®进行测量.
主要成果:
- 无论是IC还是CC,从干预前到干预后,SCS都显著增加.
- 与CC (12.9%) 相比,IC在SCS (17.8%) 中显示出更大的百分比增长.
- 两组之间随着时间的推移,SCS变化率没有显著差异 (p=0.33). 教师的采访表明,他们更愿意尝试FV和积极的食实践.
结论:
- 增加对FV的获取,特别是通过像儿童和成人护理食品计划 (CACFP) 这样的计划,可以改善儿童的FV消费.
- 将增强的食物获取与以食物为基础的学习 (FBL) 结合起来,可能会导致FV消费的更大改善.
- 基于食物的干预措施有望提高幼儿园环境中的FV摄入量和饮食行为.

Fruit Development, Structure, and Function
Fruits form from a mature flower ovary. As seeds develop from the ovules contained within, the ovary wall undergoes a series of complex changes to form fruit. In some fruits, such as soybeans, the ovary wall dries; in other fruits, such as grapes, it remains fleshy. In some cases, organs other than the ovary contribute to fruit formation; such fruits are called accessory fruits.
Cancer Prevention
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

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...
Operant Conditioning Intervention
Operant conditioning serves as a foundational principle in therapeutic interventions aimed at modifying maladaptive behaviors. Central to this approach is the notion that behaviors, both adaptive and maladaptive, are learned through reinforcement. By analyzing the environmental factors that reinforce problematic behaviors, clinicians can design interventions to weaken these reinforcements and replace maladaptive behaviors with healthier alternatives.

Community Based Intervention
Community-based interventions in mental health represent a paradigm shift from institution-centered care to treatments embedded within the fabric of local communities. By prioritizing inclusion and leveraging existing societal structures, this approach fosters a supportive environment conducive to addressing mental health challenges while promoting individual dignity and agency.

Methods of Controlling Food Spoilage
Food spoilage is caused by microbial growth or by chemical and physical changes, all of which affect the taste, texture, and safety of food.Temperature-Based PreservationRefrigeration at 0–4 °C slows microbial growth and enzyme activity, making it ideal for short-term storage. However, certain spoilage organisms—such as psychrotrophs like Listeria monocytogenes—can still proliferate at these temperatures. Freezing below -18 °C further slows biological processes by forming ice crystals, which...
