“…Pooling all studies, each 10% decrease in price increased consumption of healthful foods by 12% (95%CI: 10% to 15%) ( Fig 2A ). Fruits and vegetables were the most common target, including studies among adults in the US,[ 36 , 40 , 44 ] New Zealand,[ 27 ] South Africa,[ 23 ] and The Netherlands[ 51 ]; and among children in the US [ 34 ]. Most individual studies found significant effects; and pooling all studies, each 10% price decrease increased consumption of fruits and vegetables by 14% (95%CI: 11% to 17%).…”

The prospective impact of food pricing on improving dietary consumption: A systematic review and meta-analysis

BackgroundWhile food pricing is a promising strategy to improve diet, the prospective impact of food pricing on diet has not been systematically quantified.ObjectiveTo quantify the prospective effect of changes in food prices on dietary consumption.DesignWe systematically searched online databases for interventional or prospective observational studies of price change and diet; we also searched for studies evaluating adiposity as a secondary outcome. Studies were excluded if price data were collected before 1990. Data were extracted independently and in duplicate. Findings were pooled using DerSimonian-Laird's random effects model. Pre-specified sources of heterogeneity were analyzed using meta-regression; and potential for publication bias, by funnel plots, Begg's and Egger's tests.ResultsFrom 3,163 identified abstracts, 23 interventional studies and 7 prospective cohorts with 37 intervention arms met inclusion criteria. In pooled analyses, a 10% decrease in price (i.e., subsidy) increased consumption of healthful foods by 12% (95%CI = 10–15%; N = 22 studies/intervention arms) whereas a 10% increase price (i.e. tax) decreased consumption of unhealthful foods by 6% (95%CI = 4–8%; N = 15). By food group, subsidies increased intake of fruits and vegetables by 14% (95%CI = 11–17%; N = 9); and other healthful foods, by 16% (95%CI = 10–23%; N = 10); without significant effects on more healthful beverages (-3%; 95%CI = -16-11%; N = 3). Each 10% price increase reduced sugar-sweetened beverage intake by 7% (95%CI = 3–10%; N = 5); fast foods, by 3% (95%CI = 1–5%; N = 3); and other unhealthful foods, by 9% (95%CI = 6–12%; N = 3). Changes in price of fruits and vegetables reduced body mass index (-0.04 kg/m2 per 10% price decrease, 95%CI = -0.08–0 kg/m2; N = 4); price changes for sugar-sweetened beverages or fast foods did not significantly alter body mass index, based on 4 studies. Meta-regression identified direction of price change (tax vs. subsidy), number of intervention components, intervention duration, and study quality score as significant sources of heterogeneity (P-heterogeneity<0.05 each). Evidence for publication bias was not observed.ConclusionsThese prospective results, largely from interventional studies, support efficacy of subsidies to increase consumption of healthful foods; and taxation to reduce intake of unhealthful beverages and foods. Use of subsidies and combined multicomponent interventions appear most effective.

“…The context for studies varied greatly, with 15 Organization for Economic Co‐operation and Development (OECD) countries represented. The majority of studies were conducted in the United States (n = 56) or Canada (n = 13) . Studies encompassed food service (n = 44), grocery (n = 56), and mixed (n = 7) retail settings including cafeterias (n = 24), full service restaurants (n = 18), corner stores and/or grocery stores (n = 19), supermarkets (n = 16), vending machines (n = 13), quick‐service restaurants (n = 13), and cafés (n = 5)…”

Investigating business outcomes of healthy food retail strategies: A systematic scoping review

et al. 2019

Large changes to food retail settings are required to improve population diet.However, limited research has comprehensively considered the business implications of healthy food retail strategies for food retailers. We performed a systematic scoping review to identify types of business outcomes that have been reported in healthy food retail strategy evaluations. Peer-reviewed and grey literature were searched.We identified qualitative or quantitative real-world food or beverage retail strategies designed to improve the healthiness of the consumer nutrition environment (eg, changes to the "marketing mix" of product, price, promotion, and/or placement).Eligible studies reported store-or chain-level outcomes for measures of commercial viability, retailer perspectives, customer perspectives, and/or community outcomes. 11 682 titles and abstracts were screened with 107 studies included for review from 15 countries. Overall item sales, revenue, store patronage, and customer level of satisfaction with strategy were the most frequently examined outcomes. There was a large heterogeneity in outcome measures reported and in favourability for retailers of outcomes across studies. We recommend more consistent reporting of business outcomes and increased development and use of validated and reliable measurement tools. This may help generate more robust research evidence to aid retailers and policymakers to select feasible and sustainable healthy food retail strategies to benefit population health within and across countries.

“…16-18 For example, Kottke and colleagues discovered that reducing salad bar prices in a worksite cafeteria by 50% resulted in three times more salad bar sales during the intervention period, with sales returning to normal after the intervention. Further, participants from this study indicated that the high price of salad is a barrier to selection.…”

Objective The purpose of this study was to assess the availability of worksite supports (WSS) for healthy eating and examine associations between existing supports and dietary behaviors. Methods A cross-sectional, telephone-based study was conducted with 2013 participants in four metropolitan areas in 2012. Logistic regression was used to examine associations between dietary behaviors and the availability or use of WSS. Results Those reporting the availability of a cafeteria/snack bar/food services at the worksite were more likely to consume fruits and vegetables more than twice/day, and less likely to consume fast food more than twice/week. Conclusions Study results highlight the utility of specific WSS to improve employee dietary behaviors while raising questions about why the presence of healthy foods at the worksite may not translate into employee consumption of such foods.
