“…Their focus is on meeting daily consumable needs, including fresh perishables [ 28 ]. They share similarities to fruit and vegetable stores in New Zealand [ 29 ], in their equal or better availability of healthy products (e.g., lower cost) compared with supermarkets [ 30 ]. In addition, given a greater number of service departments in limited assortment food stores compared with convenience stores, they offer more ways in which to promote fruit and vegetable purchasing.…”

Background Modifying the environment to promote healthy foods is a population-based approach for improving diet. This study evaluated the outcome effectiveness of a food store intervention that used structural and social change strategies to promote fruits and vegetables. It was hypothesized that intervention versus control store customers would improve their consumption of fruits and vegetables at 6 months. Trial design Clustered randomized controlled trial Methods Sixteen pair-matched stores were randomized to an intervention or wait-list control condition. With the research team’s support, intervention stores modified the availability, accessibility, and promotion of fruits and vegetables, including augmenting produce displays within the store and building employees’ capacity to place and promote fruits and vegetables throughout the store (Phase 1), followed by the delivery of a customer-directed marketing campaign for 6 months (Phase 2). From months 7 to 12, stores were encouraged to maintain strategies on their own (Phase 3). Customer-reported daily fruit and vegetable consumption (cups/day) were collected by blinded research assistants at three time-points (baseline, 6 months and 12 months post-baseline) from 369 participating customers (an average of 23/store). Secondary outcomes included customer-reported fruit and vegetable purchasing and other behaviors. Results The study retained the 16 stores and most customers at 6 (91%) and 12 (89%) months. Although significant differences were not observed in the overall sample for vegetable consumption, male customers of intervention versus control stores consumed significantly more fruit daily at 6 months [mean (standard deviation) cups at baseline and six months; intervention: 1.6 (1.5) to 1.6 (1.5) vs. control: 1.4 (1.2) to 1.1 (0.8)]. However, this difference was not observed at 12 months, or among females. There was an overall increase in dollars spent at the targeted store in the intervention versus control condition among male versus female customers at 6 months; however, no change was observed in the percent of dollars spent on fruits and vegetables at the targeted store. Frequency of shopping at the targeted store did not modify intervention effects. Conclusions Structural and social change interventions can modify customers’ behavior in the short-term. Future research should consider methods for achieving longer-term changes, and potential generalizability to other products (e.g., energy-dense sweet and savory products).

“…The Nutritrack database records the products that display HSR (applied voluntarily by food manufacturers) and provides the estimated HSR for all products, only a limited percentage of products display HSR (24% of products 35 ). The process of estimating HSR used by Nutritrack is described elsewhere 36 and utilises the published algorithm and required nutrients (energy, saturated fat, sodium, total sugar, dietary fibre and protein) and food components (fruit, vegetable, nut and legume content) 37 . In this study, estimated HSR values were used, and a HSR of ≥3.5 was used as the benchmark to identify healthier products 38 .…”

AimsPlant‐based eating patterns are recommended for human and planetary health. Plant‐based protein sources in supermarkets include traditional options and plant‐based meat analogues. This cross‐sectional survey examined the nutritional content, healthiness, cost and labelling of these products.MethodsNutrient content and claims on canned legumes (plain [N = 64] and flavoured [N = 25]), canned baked beans (N = 23), dried legumes (N = 21), tofu (plain [N = 8] and flavoured [N = 5]), falafels (N = 14), meat analogues (meat‐free burgers [N = 11], meat‐free sausages [N = 10] and ‘other’ meat‐free products [N = 20]) were obtained from a database of packaged foods in New Zealand. Mean (SD) energy, protein, total fat, saturated fat, sodium and dietary fibre content (per 100 g) was calculated for each category. Healthiness was assessed using an estimated Health Star Rating (Rating ≥3.5 considered ‘healthy’). Product data were linked with household purchasing data from the 2019 Nielsen IQ® consumer panel to calculate mean purchase price/100 g/category. The number and type of nutrition claims were compared across categories.ResultsThe highest mean protein content was ‘other’ meat‐free products (14.8 ± 6.9 g/100 g). Meat‐free sausages had the highest sodium and saturated fat content (643 ± 148 mg/100 g, 3.7 ± 4.5 g/100 g). Overall, few meat analogues (N = 5, 12%) scored an estimated Health Star Rating ≥3.5. Dried legumes were the cheapest plant protein (mean ± SD) purchase price = NZ $0.30 ± 0.16/100 g), compared with ‘other’ meat‐free products (purchase price = NZ $2.57 ± 0.88/100 g). The most common nutrition claims on meat analogues were about protein content. Dietary fibre claims were the most common on canned and dried legumes.ConclusionMeat analogues offer convenience, however, may be less healthy and more expensive than traditional plant‐based proteins. This study assists dietitians in providing accurate consumer messaging about healthy plant‐based proteins.

“…By 2018, only 21% of the NZ supermarket packaged products displayed the manufacturer-calculated HSR score on the pack [ 2 ]. Thus, for the purposes of this study, we estimated the HSR score for all products using the stepwise approach and the HSR Calculator 2018 provided by The New Zealand Ministry for Primary Industries; further details are available in Tawfiq et al (2021) [ 5 ]. Estimated HSR scores were categorized as <3.5 stars (unhealthy) and ≥3.5 stars (healthy) for analyses [ 16 ].…”

“…We used data for 1,800 NZ households who purchased food in stores, and this approach was consistent with that used for in-store data collection for Nutritrack 2019. Households are based in major and secondary urban sites (according to the definition of Statistics NZ [ 22 ]), which accounts for 92% of the country’s population [ 5 ]. Price information was estimated from all product purchases made by panel members between October 2018 and October 2019.…”

“…New Zealand (NZ) has a high prevalence of nutrition-related disease (NCD) [ 1 ], with poor diets characterized by energy-dense, nutrient-poor foods and beverages, accounting for nearly 20% of illness and early death in 2017 [ 1 ]. Furthermore, there is an inequitable food environment in NZ which promotes the consumption of unhealthy foods [ 2 , 3 , 4 , 5 , 6 , 7 ], including the steady growth of the packaged food industry, which consequently has an important role to play in improving population diets and preventing NCDs [ 2 ]. In NZ, supermarkets account for ~75% of all purchases of packaged foods [ 8 ], and the supermarket food environment consists of a duopoly of two supermarket retailers: Foodstuffs and Woolworths [ 9 ].…”

We aimed to compare New Zealand private label (PL) and branded label (BL) packaged food products in relation to their current (2019) healthiness (sodium and sugar contents, and estimated Health Start Rating (HSR) score), display of the voluntary HSR nutrition label on the package, and price. Healthiness and HSR display of products were also explored over time (2015 to 2019). Data were obtained from Nutritrack, a brand-specific food composition database. Means and proportions were compared using Student t-tests and Pearson chi-square tests, respectively. Changes over time were assessed using linear regression and chi-square tests for trends (Mantel–Haenzel tests). Altogether, 4266 PL and 19,318 BL products across 21 food categories were included. Overall, PL products in 2019 had a significantly lower mean sodium content and price, a higher proportion of products with estimated HSR ≥ 3.5/5 (48.9% vs. 38.5%) and were more likely to display the HSR on the pack compared with BL products (92.4% vs. 17.2%, respectively). However, for most food categories, no significant difference was found in mean sodium or sugar content between PL and BL products. In the period 2015–2019, there were no consistent changes in estimated HSR score, sodium or sugar contents of PL or BL products, but there was an increase in the proportion of both PL and BL products displaying HSR labels. In most food categories, there were PL options available which were similar in nutritional composition, more likely to be labelled with the HSR, and lower in cost than their branded counterparts.
