Research shows that convenience store interventions combining multiple strategies, such as improving availability, positioning healthy foods prominently, adjusting prices, and adding informational signs, successfully increase purchases and consumption of healthy foods, especially fruits and vegetables. According to Gram Research analysis of 28 studies, multicomponent approaches were most effective, with most interventions reporting improvements in diet-related outcomes across high-income countries.
A comprehensive review of 28 studies shows that convenience stores can help customers make healthier food choices through simple changes like moving healthy foods to better locations, adjusting prices, and adding helpful signs. According to Gram Research analysis, the most effective approach combines multiple strategies, like placing fruits and vegetables at eye level while making junk food less visible and more expensive. While results are promising, researchers note that study quality varied, and more high-quality research is needed to confirm the best ways to redesign convenience stores for better nutrition.
Key Statistics
A 2026 systematic review of 28 studies published in Obesity Reviews found that most convenience store interventions successfully increased purchases and consumption of healthy foods, particularly fruits and vegetables, across high-income countries.
According to a 2026 systematic review analyzing 20 intervention studies, 4 observational studies, and 4 gray literature reports, multicomponent approaches combining availability, positioning, and signage strategies were most effective at improving healthy food purchasing in convenience stores.
A 2026 systematic review of convenience store interventions found that strategies using multiple approaches, such as moving healthy foods to eye level, adjusting prices, and adding signs, were significantly more effective than single-strategy interventions at improving diet-related outcomes.
The Quick Take
- What they studied: Whether changes to convenience stores, like moving healthy foods to better spots, changing prices, or adding signs, actually help people buy and eat more fruits, vegetables, and other nutritious foods.
- Who participated: Researchers looked at 28 different studies conducted between 2005 and 2024 in wealthy countries. These studies included 20 intervention projects where researchers made changes to stores, 4 observational studies that watched what people did, and 4 reports from gray literature sources.
- Key finding: Most studies showed that convenience store changes worked, people bought and ate more healthy foods, especially fruits and vegetables. The best results came from stores that used multiple strategies at once, like moving healthy foods to eye level, making them cheaper, and adding signs that encouraged people to buy them.
- What it means for you: If your local convenience store makes these changes, you’ll likely find it easier to make healthier choices. However, these changes work best when stores combine several strategies together, not just one. Results may vary depending on your community and which specific changes your store makes.
The Research Details
Researchers searched seven different databases and other sources to find all studies about convenience store changes and healthy eating between 2005 and 2024. They looked for studies that tested strategies like changing which foods were available, moving healthy foods to better locations in the store, adjusting prices, or adding signs and information. The researchers carefully checked each study to make sure it measured whether people actually bought or ate more healthy foods.
The review included 20 studies where researchers actually made changes to convenience stores and measured the results, 4 studies that simply observed what people bought without making changes, and 4 reports from other sources. This mix of study types helped researchers understand both what works and how real-world convenience stores operate.
The researchers followed strict guidelines (called PRISMA) to make sure their review was thorough and fair. They also registered their plan ahead of time with PROSPERO, which is a database that tracks systematic reviews to prevent bias.
This research approach is important because convenience stores are where many people actually shop for food, especially in neighborhoods without supermarkets. By looking at all the available evidence together, researchers can see patterns about what strategies work best. This helps policymakers decide which changes to support and helps store owners understand what changes might improve their customers’ health.
The researchers found that while most studies showed positive results, the quality of the studies varied quite a bit. Many studies had moderate to high risk of bias, meaning they weren’t perfectly designed. Some studies were small, and others didn’t follow the best scientific methods. This means the results are promising but not definitive, more high-quality research is still needed to be completely certain about the best approaches.
What the Results Show
The review found that most convenience store interventions successfully increased purchases and consumption of healthy foods, particularly fruits and vegetables. This is significant because convenience stores are often the primary food source in many communities, especially in areas without nearby supermarkets.
The most effective interventions used multiple strategies together rather than just one change. For example, stores that combined moving healthy foods to more visible locations, offering better prices on nutritious items, and adding informational signs saw the best results. These multicomponent approaches worked because they made healthy choices easier, cheaper, and more noticeable all at the same time.
Interventions that focused on availability (stocking more healthy options), positioning (placing them where customers would see them), and signage (adding helpful information) were particularly successful. Some studies also found that making unhealthy foods less convenient or more expensive helped encourage healthier choices.
The improvements in purchasing behavior were consistent across different types of convenience stores and communities, suggesting these strategies could work in many different settings.
Beyond just purchasing behavior, some studies measured actual dietary changes in customers’ overall eating patterns. These studies found that convenience store interventions contributed to improved diet quality over time. A few studies also looked at cost-effectiveness, though the review noted that more research on this topic is needed. Some interventions also appeared to reduce barriers to healthy eating by making nutritious foods more accessible and affordable in neighborhoods that previously had limited options.
This systematic review builds on earlier research showing that environmental changes in food stores influence purchasing decisions. Previous studies in supermarkets had shown similar results, but convenience stores are different, they’re smaller, have different customer bases, and often serve communities with fewer food options. This review confirms that the same principles work in convenience stores, which is important because it expands the evidence base beyond just large supermarkets. The findings align with behavioral economics research showing that people’s choices are heavily influenced by what’s visible, available, and affordable.
The researchers identified several important limitations. First, study quality varied significantly, with many studies showing moderate to high risk of bias. Second, most studies were conducted in high-income countries, so results may not apply everywhere. Third, many studies were relatively short-term, so it’s unclear if healthy eating changes last over months or years. Fourth, few studies measured cost-effectiveness, so it’s hard to know if these changes are affordable for store owners. Finally, some studies didn’t adequately measure whether changes actually improved people’s overall health, only whether they bought more healthy foods.
The Bottom Line
Based on this research, policymakers should consider supporting convenience store interventions that combine multiple strategies: improving availability of healthy foods, positioning them prominently, adjusting prices to make them more affordable, and adding clear signage. Store owners interested in supporting customer health should implement these multicomponent approaches rather than single changes. Confidence in these recommendations is moderate to good for purchasing behavior, but lower for long-term health outcomes.
Policymakers, public health officials, and store owners should care about this research because it shows practical ways to improve community nutrition. Customers in neighborhoods with limited food options should care because these changes could make healthy eating easier and more affordable. Community health organizations should care because they can advocate for these changes. However, this research is less directly applicable to people who already have access to full supermarkets with many healthy options.
Changes in purchasing behavior can happen relatively quickly, some studies showed results within weeks or months of store changes. However, changes in overall diet quality and health outcomes take longer, typically several months to a year or more. The longest-lasting benefits likely come from sustained changes, meaning stores need to keep these strategies in place over time rather than trying them temporarily.
Frequently Asked Questions
Do convenience store changes actually help people eat healthier?
Yes, research shows most convenience store interventions increase healthy food purchases, especially fruits and vegetables. The most effective stores combine multiple strategies like better positioning, pricing, and signage rather than making just one change.
What specific changes do convenience stores need to make to help customers eat better?
The most effective approach combines availability (stocking more healthy options), positioning (placing them at eye level and in prominent locations), pricing (making them more affordable), and signage (adding helpful information about nutrition benefits).
How long does it take to see results from convenience store healthy eating interventions?
Changes in purchasing behavior can happen within weeks or months of store changes. However, improvements in overall diet quality and health outcomes typically take several months to a year or longer to become apparent.
Are convenience store healthy eating interventions effective in all types of communities?
Research shows these interventions work across different convenience store settings in high-income countries. However, most studies were conducted in wealthy nations, so effectiveness in other regions remains unclear and needs more research.
What’s the difference between single and multicomponent convenience store interventions?
Single interventions make one change, like adding signs. Multicomponent interventions combine several strategies simultaneously, such as moving healthy foods to better locations, lowering prices, and adding signs, which research shows are significantly more effective.
