Product reformulation and nutritional improvements after new competitive food standards in schools

The Impact of Non-Fiscal Mandatory and Voluntary Policies and Interventions on the Reformulation of Food and Beverage Products: A Systematic Review

Background/Objectives: Low quality diets are a risk factor for non-communicable diseases; therefore, improving diet quality is a public health and policy priority in the UK and elsewhere. Reformulating food/beverage products to make them healthier may be an effective approach. Evidence suggests that fiscal interventions, notably taxes/levies on soft drinks, can lead to reformulation but the evidence for voluntary or mandated non-fiscal interventions is less clear. We aimed to review and synthesise contemporary evidence to determine whether non-fiscal policies/interventions result in the reformulation of food/beverage products Methods: In April 2023, we systematically searched ten international academic and nine grey literature databases. We included real-world study designs, all nutrients, in- and out-of-home sectors, and studies published from 2013, to ensure policy relevancy. We excluded modelling studies. Using the Synthesis Without Meta-Analysis method we conducted vote counting of studies based on the direction of effect and narrative synthesis by intervention type. Risk of bias was assessed using a tool developed by the EPPI-Centre and quality was assessed using GRADE. Results: We included 77 real-world studies from 19 countries, reporting 100 non-fiscal policies/interventions. Most commonly, these were reduction targets (n = 44), front-of-pack labels (n = 23), and advertising standards (n = 9). Most interventions were voluntary (n = 67), compared to mandatory (n = 33), and focused on the in-home sector (n = 63). The vote counting results showed non-fiscal policies/interventions overall led to improvements in reformulation in 60/63 studies with a valid direction of effect (95%, 95% CI 0.869, 0.984, p < 0.001). Mandatory implementations were more successful than voluntary implementations with 15/15 showing an improvement (100%, 95% CI 0.796, 1], p < 0.001), compared 40/43 showing an improvement (93%, 95% CI 0.814, 0.976, p < 0.001). Most of the studies were of low quality, due to the observational nature of the studies. Sodium was the most commonly targeted nutrient (n = 56) and was found to be reformulated in most studies. Causation is difficult to establish from real-world studies, but evidence suggests that regulatory and multi-component strategies may be effective at driving reformulation. Conclusions: Non-fiscal policies/interventions can play an important role in driving reformulation, alongside fiscal measures.

What is the impact of food reformulation on individuals' behaviour, nutrient intakes and health status? A systematic review of empirical evidence

Food reformulation aimed at improving the nutritional properties of food products has long been viewed as a promising public health strategy to tackle poor nutrition and obesity. This paper presents a review of the empirical evidence (i.e., modelling studies were excluded) on the impact of food reformulation on food choices, nutrient intakes and health status, based on a systematic search of Medline, Embase, Global Health and sources of grey literature. Fifty-nine studies (in 35 papers) were included in the review. Most studies examined food choices (n = 27) and dietary intakes (n = 26). The nutrients most frequently studied were sodium (n = 32) and trans fatty acids (TFA, n = 13). Reformulated products were generally accepted and purchased by consumers, which led to improved nutrient intakes in 73% of studies. We also conducted two meta-analyses showing, respectively, a -0.57 g/day (95%CI, -0.89 to -0.25) reduction in salt intake and an effect size for TFA intake reduction of -1.2 (95% CI, -1.79 to -0.61). Only six studies examined effects on health outcomes, with studies on TFA reformulation showing overall improvement in cardiovascular risk factors. For other nutrients, it remains unclear whether observed improvements in food choices or nutrient intakes may have led to an improvement in health outcomes.

Alignment Of US School Lunches With The EAT-Lancet Healthy Reference Diet's Standards For Planetary Health

By feeding more than thirty million schoolchildren daily, the National School Lunch Program's food offerings substantially influence a contributing factor to climate change: US food production methods. Modifying school lunch nutrition standards could be a policy strategy to reduce climate change while promoting human health. To estimate how school lunches could be adjusted to encourage both outcomes, we compared the composition of school lunches with the EAT-Lancet Commission's healthy reference diet science-based benchmarks for reducing food system impacts on climate change. Analyzing more than 5,000 lunches served in the US during school year 2014-15, we found that they exceeded EAT-Lancet targets for dairy, fruit, refined grains, red meat, and starchy vegetables while containing insufficient whole grains, legumes, vegetables, and nuts. In addition, estimated food costs were higher for school lunches than for lunches meeting EAT-Lancet targets. Our findings suggest that redesigning school lunches could provide high-quality nutrition while benefiting the environment and reducing food costs.

Independent Early Childhood Education Centers' Experiences Implementing the Revised Child and Adult Care Food Program Meal Pattern Standards: A Qualitative Exploratory Study

BACKGROUND

Nationally, approximately one-third of early childhood education centers participating in the Child and Adult Care Food Program (CACFP) are independently owned and operated (ie, not owned by a corporation, not affiliated with Head Start, and with no food program sponsor). Independent providers are less likely to meet CACFP standards and best practices and would benefit from additional support and technical assistance.

OBJECTIVE

To explore independent early childhood education center key informants' (KIs) (ie, directors or relevant staff) perspectives on implementing the revised CACFP standards.

DESIGN

Following qualitative exploratory design, semistructured, in-depth, telephone interviews were conducted with KIs individually.

PARTICIPANTS/SETTING

In summer 2018, 30 randomly sampled KIs from independent CACFP-participating early childhood education centers serving children ages 2 to 5 years nationwide were interviewed. Participants were sampled from respondents to a previously completed nationwide survey of providers.

MAIN OUTCOMES

KIs' perspectives on the CACFP program and revised meal pattern standard implementation.

ANALYSIS PERFORMED

After audio recordings were professionally transcribed and reviewed, constant comparative analysis was conducted using Atlas.ti v8 qualitative software (Atlas.ti. version 8 for Windows, 2018, Scientific Software Development GmbH).

RESULTS

KIs indicated that program benefits (eg, health and nutrition benefits, reimbursement, guidelines, and training) outweighed challenges experienced. Challenges associated with revised CACFP standards implementation (eg, availability or acceptability of new, creditable foods) were impacted by enhanced CACFP standards status, reported revised standards, and availability or utilization of outside support. KIs desired more contact with their state representative. KIs found the training and technical assistance on the revised standards useful and suggestions to enhance future training and technical assistance (eg, increasing accessibility, training resources, and audience-specific training).

CONCLUSIONS

Overall, KIs desired additional resources, training, and increased communication from CACFP state representatives specific to CACFP-approved and reimbursable products, menu ideas, recipes, and cooking demonstrations. The present study suggests that a more tailored training and technical assistance approach is necessary as reported benefits, challenges, and program needs varied based on state-enhanced CACFP standards, reported familiarity with the revised meal pattern, and reported outside support.

Post-Healthy, Hunger-Free Kids Act Adherence to Select School Nutrition Standards by Region and Poverty Level: The Healthy Communities Study

OBJECTIVE

This study determined the extent to which schools adhered to select nutrition and wellness provisions of the 2010 Healthy, Hunger-Free Kids Act and examined differences by US region and school poverty level.

DESIGN

Comparison of cross-sectional observational data from the Healthy Communities Study (2013-2015) by region and school poverty level.

PARTICIPANTS

A total of 401 US elementary and middle schools.

MAIN OUTCOME MEASURES

Adherence with federal nutrition standards for meals and competitive foods; extent of implementation of select aspects of school wellness policies.

ANALYSIS

Descriptive statistics and multivariate regression were used. Differences were examined by school poverty level and region, adjusting for other school- and community-level covariates.

RESULTS

Most schools reported meeting reimbursable school meal nutrition standards (74%); more schools in the West met nutrition standards (82%) than in the Midwest (64%). Most grains offered at lunch were whole grain-rich (82%), and most competitive foods complied with standards (78%) before they were required. Most schools had a wellness coordinator (80%). Lowest levels of adherence were reported for guidelines for classroom or school event foods. No differences were observed by school poverty level.

CONCLUSIONS AND IMPLICATIONS

Findings suggest that Healthy Hunger-Free Kids Act provisions were feasible across a wide variety of schools, and schools successfully implemented reimbursable school meal nutrition standards regardless of school poverty level.

The Impact of 1 Year of Healthier School Food Policies on Students' Diets During and Outside of the School Day

BACKGROUND

In 2012, Massachusetts implemented both the updated national school meal standards and comprehensive competitive food/beverage standards that closely align with current national requirements for school snacks.

OBJECTIVES

This study examines the impact of these combined standards on school meal and snack food selections, as well as food choices outside of school. In addition, this study examines the impact of these standards on nutrients consumed.

DESIGN

The NOURISH (Nutrition Opportunities to Understand Reforms Involving Student Health) Study was an observational cohort study conducted among students from spring 2012 to spring 2013.

PARTICIPANTS/SETTING

One hundred sixty students in 12 middle schools and high schools in Massachusetts completed two 24-hour recalls before (spring 2012) and after implementation (spring 2013) of the updated standards.

MAIN OUTCOME MEASURES

Changes in school meals, competitive food, and after-school snack selection, as well as nutrients consumed outside of school were examined.

STATISTICAL ANALYSES PERFORMED

Logistic regression and mixed-model analysis of variance were used to examine food selection and consumption.

RESULTS

After implementation, 13.6% more students chose a school meal (70.1% vs 56.5%; P=0.02). There were no differences in competitive food purchases but a significant decrease in the number of after-school unhealthy snacks consumed (0.69 [standard error=0.08] vs 1.02 [standard error=0.10]; P=0.009). During the entire day, students consumed, on average, 22 fewer grams of sugar daily after implementation compared with before implementation (86 g vs 108 g; P=0.002).

CONCLUSIONS

With the reduction in the number of unhealthy school snacks, significantly more students selected school meals. Students did not compensate for lack of unhealthy snacks in school by increased consumption of unhealthy snacks outside of school. This provides important new evidence that both national school meal and snack policies may improve daily diet quality and should remain strong.
