    Reliability of a Modified 24 h Dietary Recall and Veggie Meter to Assess Fruit and Vegetable Intake in New Zealand Children
    (MDPI (Basel, Switzerland), 2025-10-20) Patel VV; Perera TSH; Rush E; McArley S; Wham C; Rowlands DS; Witkowska AM
    Adequate intake of fruits and vegetables (F + V) supports healthy growth and development in children, yet many New Zealand children do not meet national dietary recommendations, and methods to evaluate intake require good reliability. Objectives: To establish the validity and reliability of a modified 24 h multiple pass recall (MPR) for evaluating F + V and carotenoid intakes in children aged 9–13 years. The reliability of the Veggie Meter® (VM®), a non-invasive reflection spectrometer to estimate skin carotenoid scores and derive blood carotenoid concentrations, was also examined. Methods: Thirty-two children (20 boys, 12 girls) completed three 24 h MPRs and parent-assisted weighed food diaries (WFDs) on randomised weekdays and weekends. Skin carotenoid scores were assessed using the VM®. The validity of the MPR was evaluated against WFDs using log-transformed Pearson correlations and mean x-axis bias. The reliability was assessed by the coefficient of variation (CV) and Pearson correlations. Results: Participants did not meet recommended F + V intakes (5–5.5 servings/day): MPR (mean fruit 1.3 servings/day; vegetables 2.0), WFD (fruit 1.3; vegetables 1.9). The MPR was a valid tool to estimate fruit and vegetable daily servings (combined-day Pearson coefficients > 0.71) with only trivial–small standardized mean bias-offset vs. WFD; however, the reliability was poor for the MPR-estimated carotenoid intake (CV 126%) and F + V intake. In contrast, the VM® was reliable (Pearson correlation 0.97–0.99) with low measurement error (CV 4.0–5.2%). Conclusions: The modified 24 h MPR was valid but unreliable for estimating F + V and carotenoid intake. The VM® demonstrated high reliability as a biomarker of skin carotenoid status in children.

    Edible insect powder for enrichment of bakery products– A review of nutritional, physical characteristics and acceptability of bakery products to consumers
    (Elsevier BV, 2023-12) Amoah I; Cobbinah JC; Yeboah JA; Essiam FA; Lim JJ; Tandoh MA; Rush E
    Bakery products including bread are traditionally good sources of carbohydrate but not nutrient-dense. Enrichment with edible insect powder could improve the quantity and quality of protein, fat and dietary fibers to bakery products. A systematic search carried out on the databases PubMed, Scopus and ScienceDirect identified 44 articles that would answer the question: what is known about the effect of enrichment of bakery products with various edible insect powders on the physical, nutritional composition and sensory properties of bakery products. The search strategy and terms applied were (Insect* OR Edible insect* OR Entomophagy*) AND (Bakery product* OR Bake* product*). Bread was the most common bakery product that was insect-enriched, yet muffins/biscuits/crackers/cookies were also reported. Commonly reported edible insects and their larvae were crickets, mealworms, palm weevil larvae, grasshoppers and African emperor moth caterpillars. Before milling into powders, insects and larvae were pre-treated by freeze-drying, oven/tray and microwave drying, blanching and roasting but was not reported for all studies. Generally, bread with up to 10% and muffins/biscuits/crackers/cookies with 5% of insect powder were acceptable to consumers. New areas of research should focus on comparing the water activity, shelf-life and cost of pre-treatment processing methods alongside the nutritional properties of edible insect powders.
