The researchers undertook a comprehensive study of household food acquisitions from 2008 through 2020, leveraging scanner data from approximately 180,000 nationally representative households. This dataset was meticulously merged with the USDA’s Purchase to Plate Crosswalk tool, enabling an estimation of the nutritional quality of foods purchased across different retail outlets. A central focus was placed on dollar stores, given their rapid expansion and increasing market share in food retail over the past decade. The analysis revealed that calories sourced from dollar store purchases have nearly doubled during the study period, climbing from 3.4% to 6.5% of overall household food calories.

Such an increase is especially pronounced in lower-income households and those headed by people of color, highlighting critical socioeconomic dimensions of the ongoing shifts in food retail. Dollar stores’ rising prominence is particularly evident in rural and underserved regions where traditional grocery stores are scarce. Despite their price appeal, these stores tend to stock calorie-dense, nutrient-poor products, such as packaged snacks and sugary beverages, while offering limited fresh produce or meats. Nevertheless, these outlets constitute just a fraction of most households’ total food acquisitions, with over 90% of calories still procured from other sources, including grocery and club stores.

First author Wenhui Feng, associate professor at Tufts School of Medicine, underscores the importance of distinguishing between the mere presence of less healthy products on dollar store shelves and the actual dietary choices households make. “What’s on the shelf does not equal what each household takes home,” Feng notes. Their analysis thus contextualizes dollar stores within a diversified shopping strategy, revealing how families may balance purchasing less nutritious items from dollar stores with more wholesome foods from other retailers.

This comprehensive research not only quantifies dollar stores’ growing footprint but also nuances prevailing assumptions about their public health impact. The dollar store phenomenon is not monolithic; rather, it reflects adaptive consumer behaviors shaped by price sensitivity, geographic access, and cultural preferences. While many consumers use dollar stores primarily to obtain affordable indulgent snacks and packaged goods, these purchases appear to substitute rather than add to similar items bought elsewhere. Senior author Sean Cash from the Friedman School elaborates, “People who buy more from dollar stores seem to buy less elsewhere, suggesting strategic, rather than indiscriminate, shopping.”

Despite the apparent substitution effect, the study raises ongoing concerns regarding the nutritional deficiencies inherent in dollar store offerings. Their typical inventory is characterized by a preponderance of calorie-rich, nutrient-poor items that may exacerbate diet-related chronic diseases, especially in populations already burdened by health disparities. The researchers emphasize the urgent need for more granular data examining the long-term health effects of reliance on dollar stores, cautioning against premature policy interventions aimed at restricting their expansion without robust evidence of harm.

Dollar stores represent the fastest growing food retail sector in the United States, with at least 37,000 shops nationwide, predominantly concentrated in the South and suburban or rural areas. Their rapid growth and market penetration have provoked widespread scrutiny from public health advocates, local governments, and economic stakeholders. Concerns extend beyond nutrition to encompass the impact of dollar stores on local economies and small business ecosystems, as well as reported challenges related to understaffing and security.

About 25 local jurisdictions have enacted policies to limit dollar store proliferation, motivated by fears of undermining neighborhood grocery stores and worsening food deserts. However, the effectiveness of these legislative measures remains uncertain. This study’s findings complicate the narrative by illustrating that, although dollar store purchases are generally less healthy, households still acquire the majority of their calories from grocery and club stores, where nutritional quality tends to be higher. This suggests that outright restrictions may not fully address underlying issues of food access and affordability.

The methodological rigor of the study derives from its use of large-scale scanner data combined with the USDA’s Purchase to Plate Crosswalk, enabling a precise estimation of dietary quality at the household level. Such data integration represents an advance in nutritional epidemiology, offering a window into real-world shopping behaviors rather than relying solely on self-reported dietary surveys. This empirical approach provides critical evidence to inform public health policies, retailer practices, and community-level interventions aimed at improving diet quality.

The evolving role of dollar stores within the food ecosystem underscores the complexity of contemporary food access challenges in the United States. They offer lower prices and convenience, critical for many households facing financial constraints and geographic barriers to full-service grocery stores. At the same time, reliance on dollar stores for staple foods may pose trade-offs in nutrient intake, necessitating a balanced perspective that considers both economic and health outcomes.

Ultimately, the researchers call for further investigation to disentangle the intricate dynamics between food retail trends, consumer behavior, and health. This includes exploring how dollar stores interact with other food outlets, examining the potential for in-store interventions to improve the nutritional profile of available products, and assessing the broader socioeconomic context influencing food purchasing decisions. As dollar stores continue to expand and reshape American food retail, such multidimensional research will be vital to guiding evidence-based policies that support both food security and dietary health.

The survey, which gathered responses from 2,204 U.S. adults between March 10 and 12, 2025, indicates that 57% of participants have consumed hot dogs at a baseball stadium. However, when the same individuals were asked about their awareness of the health risks linked to hot dogs and other processed meat products, including bacon and deli meats, the responses were concerning. A striking 51% of respondents admitted they had only a vague understanding of these risks, stating, "Somewhat, I’ve heard there are health risks but I’m unsure of what they are specifically." Additionally, 30% reported a complete lack of knowledge regarding these risks, a statistic that raises alarms among health advocates.

Noah Praamsma, MS, RDN, who serves as the nutrition education coordinator for the Physicians Committee for Responsible Medicine, articulated the gravity of the situation. With an estimated 20 million hot dogs consumed by fans throughout the baseball season, the potential health risks associated with these processed meats cannot be overlooked. Research underpins the notion that hot dogs, classified by the World Health Organization as “carcinogenic to humans,” elevate the risk of colorectal cancer significantly. In fact, the consumption of just 50 grams of processed meat daily, approximately equivalent to a single hot dog, has been shown to increase colorectal cancer risk by 18%, highlighting the need for consumer education and awareness.

The World Cancer Research Fund and the American Institute for Cancer Research further support these claims, asserting that there is robust evidence linking processed meat consumption to colorectal cancer. Of particular concern is the alarming trend of increasing colorectal cancer rates among younger demographics. According to the National Cancer Institute, there exists mounting evidence suggesting that diets high in processed meats and fats, while lacking in fruits and vegetables, correlate with early-onset colorectal cancer.

A well-documented review of cancer statistics from the American Cancer Society illustrates the evolution of colorectal cancer as a leading cause of cancer deaths. In the 1990s, it ranked as the fourth leading cause of cancer death; today, it occupies the top position among men aged 40-49 and stands as the second leading cause for women in the same age bracket. Notably, it has also emerged as the leading cause of cancer death among men aged 20-39, while being the third leading cause for women in this demographic. Such statistics accentuate the importance of modifying dietary habits, especially in light of the health risks associated with processed meats like hot dogs.

In response to these findings, the survey also explored consumer attitudes toward plant-based alternatives. When posed with the question, “Would you try a plant-based hot dog if it was available?” a total of 40% of participants expressed either definitive interest or a likelihood of considering such options. This sentiment resonates with another finding from the survey, where 63% of individuals believed that baseball stadiums should provide fans with plant-based hot dogs as a dietary option. The data points toward a growing awareness among consumers, suggesting a shift in preference that could potentially benefit both individual health and public well-being.

The positive aspect of this trend is that several stadiums across the nation are now beginning to offer plant-based hot dogs, providing fans with delicious and health-conscious alternatives to their meat-based counterparts. Praamsma emphasizes that even a small dietary shift, such as replacing one serving of processed meat daily with a plant-based option, can have significant health benefits. Research has shown that men who consume a higher amount of plant-based foods experience a 22% reduction in colon cancer risk in comparison to those who incorporate minimal plant-based items into their diet.

The conversation surrounding healthy alternatives does not stop at hot dogs. Studies accentuate the advantages of incorporating whole grains, fruits, vegetables, and legumes into your diet, indicating their protective effects against various health conditions, including colorectal cancer. Furthermore, emerging research highlights the positive health impact of processed plant-based foods, broadening the spectrum of dietary adjustments available to individuals who are health-conscious.

For those who may not be able to locate veggie dogs at their local stadium, Praamsma recommends roasted peanuts as an excellent alternative. These peanuts not only serve as a satisfying snack but are also rich in disease-fighting plant proteins and can offer protective benefits against colorectal cancer. This advice aligns with a broader message regarding the importance of making informed dietary choices that prioritize health.

In conclusion, the findings from this recent survey reveal critical insights about consumer knowledge and attitudes towards hot dogs, raising awareness about the associated health risks of processed meats. As millions of fans prepare to enjoy baseball season, it is essential for both consumers and stadium operators to recognize the importance of healthier eating options. By fostering a more informed public and providing alternatives to traditional processed meat snacks, there lies an opportunity to enhance dietary habits, lower cancer risk, and ultimately promote better health outcomes across communities.
