Detailed Description
Objective The supermarket industry now services many customers through online food shopping over the Internet. The Internet shopping process offers a novel opportunity for the modification of dietary patterns. The aim of this study was to evaluate the effects on consumers' purchases of saturated fat of a fully automated computerised system that provided real-time, personally tailored advice recommending foods lower in saturated fat.
Design Blinded, randomized controlled trial.
Setting & Participants Consumers using a commercial on-line Internet shopping site between February and June 2004.
Intervention Individuals assigned to intervention received fully automated individually tailored advice that recommended specific switches from selected products higher in saturated fat to alternate similar products lower in saturated fat. Participants assigned to control received general non-specific advice about how to eat a diet lower in saturated fat.
Outcome measure The percent of food purchased that was saturated fat. Results There were 497 randomised participants, mean age 40 each shopping for an average of about 3 people. The amount of saturated fat in the foods purchased by the intervention group was 0.66% lower (95% confidence interval 0.48-0.84, p<0.0001) than in the control group. The effects of the intervention were sustained over time and there was no difference in the average cost of the food bought by each group.
