Summary

"This trial is looking at whether getting suggestions for healthier or more eco-friendly food swaps while shopping online can help people make better choices. Participants will shop in an online store and their selections will be recorded.

Who is the study for?

This trial is for individuals interested in making healthier and more environmentally sustainable food choices. Participants should be regular online grocery shoppers willing to receive recommendations for alternative products. Specific eligibility criteria are not provided, so generally healthy adults who shop online may apply.

What is being tested?

The study tests if suggesting healthier or eco-friendlier food swaps—or a combination of both—can improve the nutritional quality and sustainability of online grocery purchases compared to usual shopping without suggestions.

What are the potential side effects?

Since this trial involves food purchasing behavior rather than medical interventions, there are no direct side effects like those associated with drugs or medical treatments. However, changes in diet can affect individual health differently.
