Food is widely understood as a cornerstone of health, however multiple barriers stand between well-intentioned, well-informed consumers and the adoption of healthier dietary practices. This mixed-methods randomized controlled trial (RCT) will measure the impact of offering a Community Sustained Agriculture (CSA) share as an employee benefit on household food environments (diets), eating behaviors, and lifestyles.
Aim: We will test a strategy to increase frequency of cooking meals at home and consumption of healthful, fresh foods by providing study participants with a CSA membership.
Study design: This is a mixed method randomized controlled trial, with survey, home-food audit, and interview components.
Hypothesis: The intervention group who received a CSA membership as an employee benefit will prepare more meals at home and consume more healthful, fresh foods compared to the control group (no CSA participation).
Using both qualitative and quantitative assessments, outcomes will be measured using 3 primary measures:
