This is a minimal risk study focusing on food purchasing and consumption in 100 subjects in the greater New Orleans area. There is evidence showing that individually-targeted vouchers effectively increase category-level food purchases in both less healthful and more healthful categories. This pilot study will investigate whether a voucher program using Instacart or a local, brick-and-mortar supermarket in New Orleans, LA lead to changes in food purchasing patterns, food consumption, food insecurity, and access to healthy food options for the participants, who are at risk of cardiovascular disease and/or cardiac complications. The study will also measure concordance between food purchasing and actual consumption.
