- Arm II (tailored websites): Participants are given unlimited access to an internet-based nutrition education program for up to 6 months. They are provided with 4 serial educational websites, at the same timepoints as in arm I, with emphasis on vegetable consumption in weeks 1 and 13 and fruit consumption in weeks 3 and 15. Materials in these websites, including new recipes with emphasis on fruits and vegetables, are tailored and then revised (or retailored) based on individual health-risk information obtained at baseline and at the 3-month online survey.
