Abstracto

Objective:

To examine the efficacy of a food-based intervention on preschool children's (3-5 years) FV consumption, as measured by skin carotenoid status (SCS) using the Veggie Meter®.

Design:

Quasi-experimental intervention with baseline (T1), pre-intervention (T2), and post-intervention (T3) assessments of children's SCS. Intervention classrooms (ICs) received the program, which featured food-based learning and gardening. Comparison classrooms (CC) received a standard curriculum. Child and Adult Care Food Program (CACFP) aligned menus were identical across all centers. Intervention teachers participated in semi-structured interviews to contextualize quantitative findings.

Setting:

Head Start centers (n=7) across three counties in North Carolina.

Participants:

183 Head Start children (n=88 IC; n=95 CC).

Results:

During the intervention period (T2-T3), significant SCS increases were observed in both groups: IC (T2=253.7, SD=77.7; T3=299.0, SD=77.4) and CC (T2=226.6, SD=77.5; T3=255.9, SD=79.9). The IC demonstrated a greater gain in SCS (17.8% gain) than the CC (12.9% gain). However, additional analyses revealed no significant difference in the SCS rate of change over time (p=0.33). Teachers reported that the intervention improved children's willingness to try fruits and vegetables and encouraged positive feeding practices beyond the mealtime setting.

Conclusions:

The findings suggest that increased access to FVs through CACFP-supported meals and snacks may influence children's overall improved FV consumption. However, improved food access paired with FBL may also support higher gains in FV consumption.

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.

Cancer Prevention

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

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 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.
In operant conditioning, behaviors that are...

Community Based Intervention

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

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...
