    Objective: The first year of life is a critical period when nutrient intakes can affect long-term health outcomes. Although household food insecurity may result in inadequate nutrient intakes or a higher risk of obesity, no studies have comprehensively assessed nutrient intakes of infants from food insecure households. This study aimed to investigate how infant nutrient intakes and body mass index (BMI) differ by household food security. Design: Cross-sectional analysis of the First Foods New Zealand study of infants aged 7–10 months. Two 24-hour diet recalls assessed nutrient intakes. “Usual” intakes were calculated using the Multiple Source Method. BMI z-scores were calculated using World Health Organization Child Growth Standards. Setting: Dunedin and Auckland, New Zealand. Participants: Households with infants (n=604) classified as: severely food insecure, moderately food insecure, or food secure. Results: Nutrient intakes of food insecure and food secure infants were similar, aside from slightly higher free and added sugars intakes in food insecure infants. Energy intakes were adequate, and intakes of most nutrients investigated were likely to be adequate. Severely food insecure infants had a higher mean BMI z-score than food secure infants, although no significant differences in weight categories (underweight; healthy weight; overweight) were observed between groups. Conclusions: Household food insecurity, in the short term, does not appear to adversely impact the nutrient intakes and weight status of infants. However, mothers may be protecting their infants from potential nutritional impacts of food insecurity. Future research should investigate how food insecurity affects nutrient intakes of the entire household.

    Starting complementary feeding with vegetables only increases vegetable acceptance at 9 months: a randomized controlled trial
    (Oxford University Press on behalf of the American Society for Nutrition, 2022-07-09) Rapson JP; Von Hurst PR; Hetherington MM; Mazahery H; Conlon CA
    BACKGROUND: Starting complementary feeding (CF) with vegetables only may improve vegetable acceptance throughout childhood. OBJECTIVES: We aimed to test whether exposure to vegetables only during the first 4 wk of CF increases later vegetable acceptance compared with a control group receiving fruit and vegetables. METHODS: In this randomized, controlled, parallel-group study, 117 Auckland infants received either vegetables only (veg-only, n = 61) or a combination of fruit and vegetables (control, n = 56) for a duration of 4 wk, starting from the first day of CF at ∼4-6 mo of age. The primary outcome measure was intake of target vegetables (broccoli, spinach) provided by the study at 9 mo of age. Daily intake of vegetables (FFQs) at 9 mo was a supporting measure. Infants' iron status (serum ferritin, hemoglobin) was examined at all time points. RESULTS: The veg-only infants consumed more broccoli and spinach than controls [mean difference (95% CI): 11.83 (0.82, 22.84) g, P = 0.036 and 10.19 (0.50, 19.87) g, P = 0.039, respectively]. Intake of pear was comparable among intervention groups (P = 0.35). At 9 mo, veg-only infants consumed target vegetables at a faster rate [mean difference (95% CI): broccoli, 3.37 (1.26, 5.47), P = 0.002; spinach, 4.12 (0.80, 7.45), P = 0.016] and showed greater acceptance for target vegetables [mean difference (95% CI): broccoli, 0.38 (0.07, 0.70), P = 0.019; spinach, 032 (0.04, 0.60), P = 0.024] than controls. The rate of eating and acceptance of pear was comparable among intervention groups (P = 0.42 and P = 0.98, respectively). Also, veg-only infants consumed more vegetables than controls [86.3 (52.5, 146.3) compared with 67.5 (37.5, 101.3) g, respectively, P = 0.042]. Introducing vegetables as the first food was not associated with 9-mo iron status. CONCLUSIONS: Providing vegetables as first foods increased vegetable intake at 9 mo of age and may be an effective strategy for improving child vegetable consumption and developing preferences for vegetables in infancy.
