The complementary feeding period (6-23 months of age) is when solid foods are introduced alongside breastmilk or infant formula and is the most significant dietary change a person will experience. The introduction of complementary foods is important to meet changing nutritional requirements(1). Despite the rising Asian population in New Zealand, and the importance of nutrition during the complementary feeding period, there is currently no research on Asian New Zealand (NZ) infants’ micronutrient intakes from complementary foods. Complementary foods are a more easily modifiable component of the diet than breastmilk or other infant milk intake. This study aimed to compare the dietary intake of micronutrients from complementary foods of Asian infants and non-Asian infants in NZ. This study reported a secondary analysis of the First Foods New Zealand cross-sectional study of infants (aged 7.0-9.9 months) in Dunedin and Auckland. 24-hour recall data were analysed using FoodFiles 10 software with the NZ food composition database FOODfiles 2018, and additional data for commercial complementary foods(2). The multiple source method was used to estimate usual dietary intake. Ethnicity was collected from the main questionnaire of the study, answered by the respondents (the infant’s parent/caregiver). Within the Asian NZ group, three Asian subgroups were identified – South East Asian, East Asian, and South Asian. The non-Asian group included all remaining participants of non-Asian ethnicities. Most nutrient reference values (NRV’s)(3) available for the 7-12 month age group are for total intake from complementary foods and infant milks, so the adequacy for the micronutrient intakes from complementary foods alone could not be determined. Vitamin A was the only micronutrient investigated in this analysis that had an NRV available from complementary foods only, allowing conclusions around adequacy to be made. The Asian NZ group (n = 99) had lower mean group intakes than the non-Asian group (n = 526) for vitamin A (274µg vs. 329µg), and vitamin B12 (0.49µg vs. 0.65µg), and similar intakes for vitamin C (27.8mg vs. 28.5mg), and zinc (1.7mg vs. 1.9mg). Mean group iron intakes were the same for both groups (3.0mg). The AI for vitamin A from complementary foods (244µg) was exceeded by the mean intakes for both groups, suggesting that Vitamin A intakes were adequate. The complementary feeding period is a critical time for obtaining nutrients essential for development and growth. The results from this study indicate that Asian NZ infants have lower intakes of two of the micronutrients of interest than the non-Asian infants in NZ. However, future research is needed with the inclusion of infant milk intake in these groups to understand the total intake of the micronutrients. Vitamin A intakes do appear to be adequate in NZ infants.

The aim of this study was to explore associations between habitual dietary fibre intake, adiposity, and biomarkers of metabolic health in Pacific and New Zealand European women who are known to have different metabolic disease risks. Pacific (n = 126) and New Zealand European (NZ European; n = 161) women (18-45years) were recruited to the PROMISE cross-sectional study(1) based on normal (18-24.9kg/m2) and obese BMI (≥30kg/m2). Body fat percentage (BF%), measured using whole body DXA, was used to stratify participants into low (<35%) or high (≥35%) BF% groups. Habitual dietary intake was calculated using the National Cancer Institute method, involving a 5-day-food-record and a semi-quantitative FFQ. Fasting blood was analysed for glucose, insulin, and lipid profile. NZ European women in the low- and high-BF% groups were older, less socioeconomically deprived, and consumed more dietary fibre (median 23.7g/day [25-75-percentile, 20.1, 29.9]; 20.9 [19.4, 24.9]) than Pacific women (18.8 [15.6, 22.1]; 17.8 [15.0, 20.8]; both p<0.001), respectively. Pacific women consumed a higher proportion of their total fibre intake from discretionary fast foods, in contrast NZ European women consumed more dietary fibre from wholegrains. Regression analysis controlling for ethnicity, age, socioeconomic deprivation, energy intake, protein, total carbohydrate, and fat intake showed significant inverse associations between higher dietary fibre intake and BF% and visceral fat% (β = −0.47, 95% CI = −0.62, −0.31, p<0.001; β = −0.61, [−0.82, −0.40], p<0.001, respectively) among both Pacific and NZ European women. LDL-C (β = −0.04, [−0.06, −0.01]) was inversely associated with fibre intake following further adjustment for BF%-groups in NZ European women. Despite differences in intake, dietary fibre was inversely associated with adiposity and metabolic disease risk in both Pacific and NZ European women. However younger woman living in areas of higher socio-economic deprivation who consumed a higher proportion of total dietary fibre intake from discretionary fast foods were more likely to have low dietary fibre intakes than older, wealthier women. These women were also more likely to be Pacific women. Increasing habitual dietary fibre intake could help to reduce adiposity and metabolic disease risk; so implementing policies that make health-promoting high fibre foods more affordable, ensuring households have sufficient income to purchase nutritious food and limiting the amount of unhealthy food marketing that low income communities are exposed to should be public health priorities.

The prevalence of food allergies in New Zealand infants is unknown; however, it is thought to be similar to Australia, where the prevalence is over 10% of 1-year-olds(1). Current New Zealand recommendations for reducing the risk of food allergies are to: offer all infants major food allergens (age appropriate texture) at the start of complementary feeding (around 6 months); ensure major allergens are given to all infants before 1 year; once a major allergen is tolerated, maintain tolerance by regularly (approximately twice a week) offering the allergen food; and continue breastfeeding while introducing complementary foods(2). To our knowledge, there is no research investigating whether parents follow these recommendations. Therefore, this study aimed to explore parental offering of major food allergens to infants during complementary feeding and parental-reported food allergies. The cross-sectional study included 625 parent-infant dyads from the multi-centred (Auckland and Dunedin) First Foods New Zealand study. Infants were 7-10 months of age and participants were recruited in 2020-2022. This secondary analysis included the use of a study questionnaire and 24-hour diet recall data. The questionnaire included determining whether the infant was currently breastfed, whether major food allergens were offered to the infant, whether parents intended to avoid any foods during the first year of life, whether the infant had any known food allergies, and if so, how they were diagnosed. For assessing consumers of major food allergens, 24-hour diet recall data was used (2 days per infant). The questionnaire was used to determine that all major food allergens were offered to 17% of infants aged 9-10 months. On the diet recall days, dairy (94.4%) and wheat (91.2%) were the most common major food allergens consumed. Breastfed infants (n = 414) were more likely to consume sesame than non-breastfed infants (n = 211) (48.8% vs 33.7%, p≤0.001). Overall, 12.6% of infants had a parental-reported food allergy, with egg allergy being the most common (45.6% of the parents who reported a food allergy). A symptomatic response after exposure was the most common diagnostic tool. In conclusion, only 17% of infants were offered all major food allergens by 9-10 months of age. More guidance may be required to ensure current recommendations are followed and that all major food allergens are introduced by 1 year of age. These results provide critical insight into parents’ current practices, which is essential in determining whether more targeted advice regarding allergy prevention and diagnosis is required.
