Dietary Intervention in e-Shopping Trial - DIeT
Aims
To determine the effects of tailored dietary advice on the amount of fat purchased by consumers using a commercial Internet-shopping service.
Methods
DIeT is a randomised, double-blind, controlled trial in which participants were enrolled and followed over a three month period.
Status/Results
Recruitment and follow up has been successfully completed, with 497 individuals agreeing to participate. The mean age of participants was 40 years and 88% were female. The proportion of saturated fat in the commonly purchased foods selected by the intervention group was 0.66% lower (95% confidence interval 0.48-0.84, P<0.001) 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 purchased by each group.
