まとめ
無料のフルーツと野菜 (FV) の提供は,介入なしにFVの廃棄物を増加させるが,摂取量を増加させない. 無料のFVとコーチングを組み合わせることは,FVの消費を改善し,食品の浪費を減らすために非常に重要です.

背景:
- 政策は,果物と野菜 (FV) の消費を促進し,食品の浪費を減らすことを目的としています.
- FVの消費を補助することで,食品廃棄物が意図せず増加するかどうかについての研究は限られている.
研究 の 目的:
- 無料フットボールの提供とスマートコーチングの介入がフットボールの摂取量,廃棄物,在庫に与える影響を評価する.
- 介入が食品の浪費を減らすことができ,栄養価が低い食品のFV代替を奨励するかどうかを評価する.
主な方法:
- ルイジアナ州バトンルージュの46世帯を対象としたランダム化比較試験.
- 参加者は,介入前のおよび後の3日以上,FVの摂取と廃棄物を測定しました.
- 2つのグループ:集中的な介入 (廃棄物の削減,FVの置換) とコントロール,どちらも無料のFVを受け取る.
主要な成果:
- コントロールグループ:フリーFVは,在庫と廃棄物の発生が増加したが,摂取は減少しなかった.
- 治療群:対照群と比較して,FVの摂取量が増加し,FVの在庫が凍結した.
- 食事の質 (HEI),総カロリー摂取量,総FV在庫,またはプレート廃棄物のグループ間の有意な違いはありませんでした.
結論:
- 無料のFVの提供だけでは,FVの摂取を増加させず,FVの廃棄を悪化させます.
- 無料のFVと組み合わせた介入は,FVの消費を改善するために不可欠です.
- FV廃棄物の大幅な削減は,より集中的な介入戦略を必要とします.

Fruit Development, Structure, and Function
25.5K
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.

Regulation of Water Intake
2.9K
Osmolality refers to the number of solute particles per kilogram of solvent in a solution. Plasma osmolality specifically indicates the total number of solute particles per kilogram of water in blood plasma. This value reflects the body's hydration status and is tightly regulated through mechanisms controlling water intake and output. While water consumption is a conscious decision, the body has intrinsic regulatory systems to maintain fluid balance. Dehydration, a state of water deficit...

Regulation of Food Intake
2.9K
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...

Nursing Interventions I: Taxonomy of Nursing Interventions
4.0K
Nursing interventions are chosen as part of the planning process to achieve patient outcomes. Once nursing diagnoses are determined, the goals and outcomes are specified, then the nursing interventions are selected and individualized according to the patient's situation.
A nursing intervention is a treatment or action based on scientific concepts and knowledge from the nursing, behavioral, and physical sciences. Identifying and prioritizing nursing interventions based on the desired outcome...

Household Wiring And Electrical Safety
1.7K
Companies that supply power to most modern households use three conductors, typically called a three-wire line. While one is neutral, the other two are both at 120 V but with opposite polarity, giving a voltage of 240 V between them. With a three-wire line, high-power appliances that require 240 V, such as electric stoves and clothes dryers, are linked between the two hot lines. 120 V appliances can be connected between the neutral and either of the hot lines. The neutral side, which is always...

Trial and Error and Algorithm
435
A problem-solving strategy is a plan of action used to find a solution. Different strategies have distinct action plans. Trial and error involves trying different solutions until one works. For instance, to fix a broken printer, you might check ink levels, ensure the paper tray isn't jammed, and verify the printer's connection to your laptop. This method can be time-consuming but is commonly used. Thomas Edison, for example, used trial and error to find a suitable filament for the light...
