Participants in the intervention group of this study will receive weekly home deliveries of fruit & vegetables for 3 months. The primary objective of this study is to determine if increased access to fruits and vegetables leads to sustained dietary changes, measured through changes in the Healthy Eating Index (HEI). Secondary objectives are to determine whether increased fruit and vegetable access (increased HEI) ultimately leads to improved cardiovascular (CV) health indicators (e.g., body mass index, waist circumference, blood pressure, and levels of blood lipids and hemoglobin A1c).

| Intake of fruits and vegetables measured by changes in Healthy Eating Index (HEI) | The HEI uses a scoring system to evaluate a set of foods. The scores range from 0 to 100. An ideal overall HEI score of 100 reflects that the set of foods aligns with key dietary recommendations from the Dietary Guidelines for Americans. | 6 months |
