Background:

Policies seek to both increase fruit and vegetable (FV) consumption and reduce wasted food, though few have investigated if subsidizing FV consumption leads to more waste.

Objective:

We evaluate changes in FV intake, waste, and inventories after free provision of supplemental produce and delivery of a smart coaching intervention to reduce food waste and replace less nutritious foods with FV.

Methods:

Adults from households in Baton Rouge, Louisiana measured food intake and waste for ≥3 days before and after intervention. Households were randomized to an intensive intervention to reduce food waste and replace less nutritious foods with FV (n=23) or to a control intervention (n=23). Both received free FV and measured FV inventories before and after intervention.

Results:

Among control participants, free FV provision led to no significant changes in FV intake (-0.07, p=0.71) or diet quality measured by Healthy Eating Index (HEI, -1.93, p=0.33) but did increase FV inventories (4.89 kg, p=0.04) and the number (9.53 events/period, p<0.001) and magnitude (100.5 g/event, p=0.005) of FV waste events, while total caloric intake (-132.7 kcal/day, p=0.04) decreased. After receiving free FV, and compared to controls, treatment participants increased FV intake (0.85 servings/d, p=0.002) and frozen FV inventories (1.78 kg, p=0.04). After intervention, treatment did not significantly differ from control in HEI (-2.77, p=0.34), total caloric intake (147.8 kcal/day, p=0.13), total FV inventories (-1.83 kg, p=0.51), plate waste (-22.2 g/p/day, p=0.09), or the number (-3.57, p=0.24) or magnitude (-66.4, p=0.11) of FV waste events.

Conclusions:

Providing free FVs without focused interventions to improve diet quality and reduce waste fails to increase FV intake and increases FV waste. Pairing interventions with free FV provision appears critical to translating program resources into improved FV intake, while efforts to substantially decrease FV waste require more intensive effort. This trial was registered at ClinicalTrials.gov (NCT05061888).

Fruit Development, Structure, and Function

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.

Regulation of Water Intake

Regulation of Water Intake

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

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...

Nursing Interventions I: Taxonomy of Nursing Interventions

Nursing Interventions I: Taxonomy of Nursing Interventions

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

Household Wiring And Electrical Safety

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

Trial and Error and Algorithm

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...
