The purpose of this study is to test the effect of group-based nutrition advice plus gardening (intervention) versus group-based nutrition advice alone on dietary intake of fruits and vegetables, physical activity, and lifetime risk for cardiovascular disease (CVD).
Study participants will be randomly assigned to attend group sessions related to gardening with nutrition advice or nutrition advice alone. The main goal of the intervention will be to encourage participants to increase their intake of fruits and vegetables.

Plasma Carotenoids
The primary outcome is between group differences in total plasma carotenoids from baseline to 16 weeks. Plasma carotenoids are a reliable bio-marker of dietary intake of F\&V.
Time frame: 4 months
Self-reported dietary intake
Investigators will also test the between group differences in self-reported servings of fruits and vegetables as assessed by 24-hour recalls.
Time frame: 4 months
Cardiovascular disease risk score
Differences in Cardiovascular Disease (CVD) risk score based on the American College of Cardiology/American Heart Association (ACC/AHA) lifetime CVD risk score calculation (risk score range 0-100%). Higher scores indicate greater risk of a lifetime CVD-related event.
Time frame: 4 months
Physical activity
Between group differences in minutes of physical activity as measured by the International Physical Activity Questionnaire (IPAQ), (range in minutes, 0-3000+). Higher scores indicate more physical activity.
Time frame: 4 months
