The risk of nutrition-related chronic diseases is significantly higher in low-income populations when compared with those with higher incomes. Over the course of the last century, the American diet has shifted toward higher consumption of sugar, saturated fat, added sodium, processed foods, and overall calories, while intake of fresh fruits and vegetables has starkly declined. These dietary shifts parallel the rapid rise in the national prevalence of obesity, cardiovascular disease and type 2 diabetes. With among 1 in 3 adults in the United States currently affected by obesity and over 30 million Americans (1 in 10) with type 2 diabetes, there is a growing need to invest resources in prevention and treatment. Diabetes is considered the seventh leading cause of death and is associated with $327 billion yearly in excess medical costs and lost productivity. Obesity, diabetes rates and diet quality are all associated with socioeconomic status and disparately impact low-income, Black and Hispanic persons compared to their higher-income or white counterparts.
Increasing the consumption of fruits and vegetables can improve health by promoting healthy weight and reducing blood sugar, the risk of heart disease, stroke, some types of cancer, and digestive problems. Studies have shown that even without reducing caloric consumption, increasing fruit and vegetable consumption can provide independent benefits by increasing fiber intake, reducing sodium and fat intake, and increasing the micronutrient content of the consumer's diet. There are grave disparities in access to healthy foods based on income, race, geographic location, and immigration status, which in turn drive disparities in obesity, diabetes, overall health, and quality of life.
Fruit and vegetable incentive programs are a prudent method of improving food security, while not investing in or allocating money for poor nutritional quality food. They guarantee that the money spent goes to fruits and vegetables known to improve nutritional status, and a growing body of evidence demonstrates that money allocated to the purchase of fruits and vegetables can improve diet quality, purchasing patterns and sometimes health in a statistically and clinically significant manner. Produce prescription programs have the potential to reduce health disparities resulting from differential access to healthy food. In addition to providing free or discounted access to produce, many PPRs also attempt to address other cultural and socio-contextual barriers to accessing healthy food by providing educational and skill-building programming such as cooking demonstrations, suggested family meal plans, and nutritional information at the point of purchase. The few studies that examine the effectiveness of PPRs suggest that they are associated with dietary improvements and reductions in food insecurity. Overall, fruit and vegetable incentive programs have demonstrated positive impact (with few studies reporting no impact or minimal impact) on fruit and vegetable intake and or diet quality, reduced hemoglobin A1C, and reduced body weight.
Fruit and vegetable incentive programs are designed to increase the budget share available to a household for the purchase of fruits and vegetables.14 Incentive programs have the ability to immediately increase fruit and vegetable purchases, although the benefits of increasing fruit and vegetable purchases and consumption might take longer to realize. Incentives make it possible to encourage healthier purchasing patterns that are necessary for longer term behavior change that leads to improved health status. According to a 2020 meta-analysis conducted by Engel and Ruder, overall, fruit and vegetable incentive programs have a demonstrated benefit on fruit and vegetable purchase patterns.14 In Connecticut's Lower Naugatuck Valley (LNV), poverty and low-income rates (8% and 21%, respectively, in 2017) have been increasing across the region since 2000, according to a 2019 report on community well-being in the LNV. The seven communities (Ansonia, Beacon Falls, Derby, Naugatuck, Oxford, Seymour, and Shelton) of the LNV have a combined population of approximately 140,000, with increasing racial and ethnic diversity. Food insecurity and nutrition-related chronic disease are significant issues among the area's residents, with 12% of adults reporting food insecurity. Nutrition related chronic diseases such as obesity (affecting 28% of the population) are high. Heart disease and diabetes are among the eight leading causes of premature death and account for an average of 14 and 15 years of potential life lost per disease, respectively.
